Abstract

PURPOSE:To expand an application range by using a signal circuit so as to extract only the signal of moving direction from each pulse signal outputted from a mouse main body in a mouse with output selective function so as to connect the signal to a personal computer through switching. CONSTITUTION:The mouse with output selection function consists of a mouse main body 5, a signal extraction circuit 6, a changeover switch 4 and output terminals 8 having 4 or over of connection terminals. A personal computer is connected to the mouse and four pulses in response to directions orthogonal to each other and in reverse directions of the position of a cursor on a CRT display screen of the computer are outputted from the terminals 8. In selecting one moving direction by the main body 5, a 1st pulse signal is sent in response to the direction by horizontal/vertical direction signal processing circuits 21, 22 of the extraction circuit 6 and a 2nd pulse signal to which phase is retarded in response to the selection in opposite to the moving direction are sent.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to MSXLI! The present invention relates to a mouse with an output selection function that can be connected to both a personal computer having a standard input interface and a personal computer having an ASCII serial input interface.

[Prior Art] For example, as shown in FIG. 6, a mouse 3 is one of coordinate position input devices that can easily specify a two-dimensional coordinate position on a CRT display screen 2 of a personal computer 1. When this mask 3 is moved in any direction on the table, a cursor position 4 indicating designated coordinates displayed on the CRT display screen 2 of the personal computer 1 moves in the direction in which the mask 3 is moved.

For example, such a mouse 3 is provided with a pair of detection wheels so that the rotating surfaces thereof are orthogonal to each other, and when the mask 3 is moved in any direction on the desk, each detection wheel rotates and each detection wheel rotates. A rotation detecting section attached to the shaft of the detection wheel detects the rotation angle (movement distance M of the mouse) and rotation direction (mouse movement direction) of the detection wheel. First, the attitude angle of the mouse 3 is set so that the rotation direction of each detection wheel matches the horizontal (H) direction and vertical (V) direction on the CRT display screen 2 of the personal computer 1. Then, when the mouse 3 is moved in the horizontal (H) direction, a pair of pulse signals Ha as shown in FIG. 7(a)<b) are output from a pair of output terminals corresponding to the horizontal direction.

Hb is output. Furthermore, when the mouse 3 is moved in the vertical <V) direction, a pair of pulse signals @V as shown in FIG.
a and Vb are output.

However, FIG. 7(a) shows the case where the mouse 3 is moved horizontally (H) in the direction a. In this case, the pulse signal @Ha corresponding to the moving direction a of the mouse 3 advances by a predetermined phase (vI interval To) than the pulse signal Hb corresponding to the opposite direction. Similarly, (b) in the same figure shows the case where the mouse 3 is moved horizontally (H) in the b direction, and the pulse signal Hb corresponding to the moving direction A has a predetermined phase (time) than the pulse signal Ha corresponding to the opposite direction a. Go forward by To ).

Similarly, FIG. 7(C) shows each pulse signal Va when the mask 3 is moved in the vertical (V) direction a.

(d) shows the mask 3 vertically (V) b
Each pulse signal Va when moving in the direction.

Indicates vb.

In this way, depending on the moving direction of the mouse 3, the phases of the pair of pulse signals whose moving directions are opposite to each other are reversed, so that these four pulse signals Ha, Hb, Va, V
The cursor position 4 on the CRT display screen 2 can be specified from b.

Therefore, the input interface to which the mouse 3 of the personal computer 1 is connected receives pulse signals Ha and Hb corresponding to each of the above movement directions.

Four input terminals are provided to which Va and Vb are input.

[Problems to be Solved by the Invention] However, an ASCII serial compliant input interface dedicated to a mouse that can input the pulse signals Ha, Hb, ■a, and Vb output from the mouse 3 as described above,
It is not provided in general general-purpose personal computers. That is, independent pulse signals Hap, )-1bp, Vap, and Vbp are input to four input terminals corresponding to each movement direction of an MSX-compliant input interface built into a normal personal computer 1. .

Then, a pulse signal Hap as shown in FIG. 8(a) is generated.

When Hbp is input, the cursor position 4 is moved horizontally (H) in the direction a, and the pulse signal Ha as shown in FIG.
When p and HbD are input, move the cursor position 4 horizontally (
H) in the b direction. Furthermore, when the pulse signals V ap and V bp as shown in FIG. 8(C) are input, the cursor position 4 is moved vertically (V) in the direction a, and
d) such as pulse signal V ap.

When Vbp is input, the cursor position 4 is moved vertically (V) in the b direction. In this way, each input terminal receives an independent pulse signal corresponding to each movement direction.
, Hbt), vap, and Vbp are input. Note that each pulse signal corresponding to each movement direction can generally be obtained using a joystick.

Therefore, the MSX11 receives independent pulse signals Hap, Hbp, vap, and vbp for each movement direction as described above. It was not possible to directly connect the mouse 3 to the personal computer 1 which had a standard input interface.

The present invention provides a circuit in the mouse that extracts only the signal corresponding to the direction of movement from each signal output from the mask body, so that it can be connected to a personal computer with any input interface by operating a changeover switch. The purpose is to provide a mouse with an output selection function.

[Means for Solving the Problems] The mouse with an output selection function of the present invention has four directions corresponding to four directions of movement of the cursor position on the CRT display screen of the connected personal computer, which are orthogonal to each other or opposite to each other. When one movement direction is selected, a first pulse signal is sent from the output terminal corresponding to the movement direction, and a predetermined pulse signal is output from the output terminal corresponding to the movement direction opposite to this movement direction. A mask body that sends out a second pulse signal with a phase delay, and a signal that extracts only the pulse signal with an earlier rising timing among a pair of pulse signals corresponding to mutually opposite movement directions output from this mask body. An extraction circuit is provided, and the output terminal is selectively connected to the mouse body or the signal extraction circuit using a changeover switch.

[Function] In the mouse with output selection function configured as above, when the mouse with output selection function is moved in any direction, the output terminal of the mouse body corresponding to the moving direction of the mask with output selection function and this A pair of pulse signals having a predetermined phase shift from each other are output from output terminals of the mouse body corresponding to a direction of movement 180' opposite to the direction of movement. A signal extraction circuit extracts only the pulse signal of the pair of pulse signals having an earlier rising timing, that is, only the pulse signal corresponding to the moving direction.

When this mouse with output selection function is connected to a personal computer with a general-purpose MSX-compliant input interface, when the selector switch is connected to the signal extraction circuit side, only the pulse signal corresponding to the direction of movement is extracted, and the input Output to the interface. Conversely, when connecting to a personal computer having an ASCII serial compliant input interface, if the changeover switch is connected to the mouse body side, a pair of pulse signals output from the mask body are output as they are to the input interface.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a mouse with an output selection function according to an embodiment. This mouse with an output selection function (hereinafter abbreviated as mask) is roughly divided into a mask body 5 and a signal extraction circuit 6.
, a changeover switch 7, and an output terminal 8 having four or more connection terminals. The mask body 5 receives each pulse signal Ha shown in FIG. 7 corresponding to the direction of movement of the mask.

Outputs Hb, Va, and Vb. Further, the changeover switch 7 selectively connects the output terminal 8 to the mouse body 5 or the signal extraction circuit 6.

FIG. 2 is a schematic diagram showing the appearance of the mask. A detection wheel 10 is disposed at a lower position within the housing 9, and at an upper position detects the rotation of the signal extraction circuit 6 and the detection wheel 10 and outputs each of the pulse signals Ha.

A PC board 11 is provided on which a rotation detection circuit and the like that output Hb, Va, and Vb are mounted. Further, the changeover switch 7 is attached to the side surface of the housing 9. Additionally, a switch 14a is provided on the front of the housing.

14b is attached.

The signal extraction circuit 6 has the circuit configuration shown in FIG.

That is, each pulse signal Ha,)-1b corresponding to each movement direction is output from the mouse body 5.

Input terminals 12a and 12b to which Va and Vb are input.

In addition to 13a and 13b, there are input terminals 15a and 15b to which switch signals SW1°8W2 of switches 14a and 14b provided on the surface of the housing 9 are input, and an output terminal 16a.
16b, +5 supplied from the personal computer side
V drive voltage input/output terminals 17a, 17b1 ground terminal 1
8a and 18b are provided. Furthermore, each pulse signal after extraction Ha (Hap), Hb (Hbp),
Va (Vap).

Vk) (VMI) is output 41[! It's output terminal 19a.

19b, 20a, and 20b are provided.

Further, the horizontal pulse signals Ha and Hb input to the signal extraction circuit 6 are processed by a horizontal signal processing circuit 21, and the vertical pulse signals a and Vb are processed by a vertical processing circuit 22. . Horizontal signal processing circuit 21
and the vertical signal processing circuit 22 have the same configuration, so
Only the horizontal signal processing circuit 21 will be explained. A pulse signal Ha corresponding to the horizontal (H) direction a inputted from the input terminal 12a is inputted to one input terminal of an AND gate 23a, and is also inputted to the AND gate 23a via an inverter 24a and an integrating circuit 25a consisting of a resistor and a capacitor. The signal is input to the other input terminal of the gate 23a. therefore,
AND gate 23a, inverter 24a, integration circuit 25
A constitutes a waveform detection circuit that detects the rise timing of the pulse waveform with respect to the pulse signal Ha. The rising timing signal C output from the AND gate 23a of this waveform detection circuit is input to the set terminal S of the flip-flop 27 via the Nant gate 26a. This flip-flop 27 is turned on when a 1-level signal is input to the set terminal S, and inputs an H-level output signal from the output terminal Q to one input terminal of an AND gate 28a serving as a gate circuit. Also, L to reset terminal R.
When a level signal is input, it is reset, and an H level output signal is input from output terminal 0 to one input terminal of an AND gate 28b serving as a gate circuit.

The other input terminal of each AND gate 28a, 28b receives a pulse signal Ha directly from the input terminal 12a, 12b.
Hb is input.

On the other hand, the pulse signal Hb inputted from the input terminal 12b is input to the AND gate 23a, similarly to the pulse signal Ha described above.
The signal is input to a waveform detection circuit consisting of a bark 24b and an integrating circuit 25b. The rising timing signal d output from the AND gate 23b is input to the reset terminal R of the flip-flop 27 via one input terminal of the Nant gate 26b.

Pulse signals Hb and Ha whose levels have been inverted by inverters 24b and 24a are input to the other input terminals of the Nant gates 26a and 26b, respectively. Therefore, the Nant gates 26a and 26b are connected to each AND gate 23a and 2
This is a timing signal selection circuit that selects the earlier rising timing signal from among the rising timing signals outputted from 3b.

Next, the operation of the signal extraction circuit 6 configured as shown in FIG. 3 will be explained. First, when the mouse is moved horizontally (H) on the desk in the direction a, the input terminal 12
A phase shift of a predetermined phase (time To) occurs in the pulse signals @Ha and Hb input from a and 12b. Since it was moved in the a direction, the pulse signal Ha becomes the pulse signal Hb.
This time T++ is set to about 1/4 of the entire pulse width.

Each pulse signal Ha, Hb is ant game-1-23, respectively.
a, 23b, inverters 24a, 24b.

The rising timing of the pulse waveform is detected by each waveform detection circuit consisting of the integrating circuits 25a and 25b, and the pulsed rising timing signals c and d are outputted to the Antogame 1-23.
It is output from a and 23b. Therefore, the rising timing signal C is earlier than the rising timing signal d by the time To. A rising timing signal C and a signal obtained by inverting the level of the pulse signal Hb are input to each input terminal of the Nant gate 26a. Are rising timing signal C and pulse signal Hb ffi? Therefore, the output signal e of the Nandt gate 26a becomes a signal obtained by inverting the rising timing signal C. On the other hand, the rising timing signal @d and the inverted signal of the pulse signal 1-1a are input to the input terminal of the Nant gate 26b. However, since the rising timing signal d completely overlaps with the pulse signal Ha, the Nant gate 26
The output signal f of output signal b always maintains the I'' level.

Therefore, the flip 70 knob 27 is the Nantes gate 26
Output signal et1' output from a) is set when the first L level pulse is input to the set terminal Sl\. Note that since an H level signal is always applied to the reset terminal R, this flip-flop 27 is not reset midway.

Therefore, the output signal q at the output terminal Q of the flip-flop 27 becomes H level, and the output signal at the output terminal Q becomes a level. As a result, the pulse signal Ha at the input terminal 12a
is output to the output terminal 19a via the AND gate 28a. On the other hand, the pulse signal t- inputted to the input terminal 12b
1b is cut off by the AND gate 28b, and the output terminal 19
It is not output to b.

Next, consider the case where the mouse is moved horizontally ()-1) in the b direction. In this case, as shown in FIG.
The pulse signal Hb at the input terminal 12a advances by the time To from the pulse signal HA at the input terminal 12a.

Therefore, the rising timing signal d and the pulse signal Ha
The rising timing signal C and the pulse signal Hb completely overlap without overlapping.

Therefore, an output signal @f obtained by inverting the rising timing signal j3d is output from the Nant gate 26b, and an output signal e that is always at H level is output from the Nant gate 26a.

As a result, the flip-flop 27 is connected to the Nant gate 26b.
is reset by the first pulse of the output signal f. When the flip-flop 27 is reset, the output terminal Q becomes L level and the output terminal d becomes H level. Therefore, the pulse signal Hb at the input terminal 12b is
b, is output to the output terminal 19b. On the other hand, input terminal 12
The pulse signal (a) -1a is disconnected by the AND gate 28a and is not output to the output terminal 19a.

The vertical pulse signals Va and Vb are also subjected to similar processing in the vertical signal processing circuit 22 and then output from the output terminals 20a and 20b.

In this way, when the mask is moved in any direction on the desk, only the pulse signal corresponding to the moving direction is extracted and output from the signal extraction circuit 6. That is, each pulse signal Ha shown in FIGS. 7(a) to (d) output from the mouse body 5
, Hb, Va, and Vb are converted into the respective pulse signals Hat), Hbll, Vap, and VbM shown in FIGS. 8(a) to (d).

Therefore, when connecting this mouse to a personal computer that has an ASCII serial compliant input interface dedicated to the mouse, if the selector switch 7 shown in FIG. 2 is set to the ASCII side (mouse body 5 side),
Each pulse signal Ha, Hb, output from the mask body 5
Since Va and Vb are input to the input interface of the personal computer, the personal computer operates normally and it is possible to move the cursor position on the CRT display screen by moving the mask.

On the other hand, when this mouse is connected to a personal computer having a normal MSX-compliant input interface, when the changeover switch 7 is set to the MSX side (signal extraction circuit 6 side), each of the signals output from the signal extraction circuit 6 is Pulse signals Hap, Hbp.

Since Vap and Vbp are input to the input interface of the personal computer, the personal computer operates normally and it is possible to move the cursor position on the CRT display screen by moving the mask.

In this way, depending on the type of input interface of the personal computer connected to the mouse, it is possible to connect to a personal computer having either an ASCII serial compliant or MS Therefore, the mouse can be made easy to use.

[Effects of the Invention] As explained above, according to the mouse with the output selection function of the present invention, a signal circuit that extracts only pulse signals from each pulse signal output from the mask body, without corresponding to the movement direction, is installed in the mouse. It is set up. Therefore, it is possible to connect to a personal computer having any input interface by operating a changeover switch, and the range of application can be greatly expanded.
