Abstract

PURPOSE:To input a signal that can show a large shift distance with a small shift amount by providing an adjusting means which can give the variable control to the proportion constant of an output signal that is proportional to a shift distance. CONSTITUTION:When a ball 11 moves toward an axis (x), a ball contact shaft 20 connected close to the ball 11 rotates. Thus a rotary plate 21 also rotates and a contact 22 has a contact with each B terminal 25. The input voltage supplied from a C terminal 26 emerges at a terminal 29 via the contact 22; while the voltage produced between each A terminal 24 and 25 where the con tact 22 has contacts as well as the reference voltage E emerge among a refer ence voltage terminal 30, a P output terminal 27 and a Q output terminal 28 respectively. When a double-speed switch 13 is kept ON, the output voltage emerges between output terminals 27 and 28 every time the contact 22 has contact with A and B terminals respectively. When the switch 13 is turned off, the output voltage emerges at both terminals 27 and 28 only when the contact 22 has contacts with terminals A1, A3, B1 and B3 respectively.

Description

[Detailed description of the invention] 1-Industrial application field] The present invention relates to a mouse device.

1. Prior Art] Conventionally, a mouse device, which is a computer input device, rotates when the ball of the mouse device is rotated by moving it on a desk.
A movement signal proportional to the number of rotations of the ball by a constant proportionality constant was converted into an electrical signal and output.

[Problem that the invention seeks to solve]

With the above-mentioned mouse device, which is a conventional computer input device, when trying to input a large movement signal to the computer, the proportionality constant of the electric signal input to the computer, which is proportional to the movement distance of the mouse device, is constant. The drawback is that the mouse device has to be moved a lot.

[Means for solving problems]

The mouse device of the present invention can variably adjust the proportionality constant of the output signal that is proportional to the moving distance! I can do it! We have provided means to do so.

Embodiment] Next, an example of the fruit market of the present invention will be described with reference to the drawings.

Figure 1 (a>, (b) is a bottom view showing one embodiment of the present invention, respectively. Figure 2 (:'L) is a bottom view showing an example of the connection with the ball of Figure 1 (, 1). The lower surface of the terminal plate of the movement signal generating part of the movement signal generation part of the
) is a cross-sectional view of line l) -1) ' in Figure 2(a),
The figure shows the circuit of the movement signal generating section in Figure 1 (a>), and Figure 4 (Xl>, (b) shows the circuit in Figure 3 (when the r'i speed switch is off and on, respectively). FIG. 3 is an output waveform diagram at each output terminal of FIG.

As shown in FIGS. 1A and 1B, the mouse device 1 of this embodiment has a ball 11 at the bottom, an auxiliary ball 12, a double speed switch 13 on the side, and left and right buttons 14 and 15. A movement signal generating section (X-axis) 2 and a movement signal generating section (y-axis) 3 are coupled to the ball 11.

Next, as shown in FIGS. 2(a) and 2(b), the movement signal generating unit 2 for movement in the X-axis direction includes a rotary plate 21 on which the ball 11 and the ball contact shaft 20 are closely coupled. , a contactor 22 connected to the rotary plate 21, and A terminals (A1°A2, A3, A4) 24 arranged on the terminal plate 23. B terminal (B+, B2.

B3, B4)25. Each A terminal 24 and each B terminal 25 are connected to the double speed switch 13, respectively, as shown in FIG.

Although not shown, the movement signal generation section 3 for movement in the y-axis direction also has the same configuration as the movement signal generation section 2 described above.

Next, FIGS. 2 and 3 show the operation of this embodiment.

This will be explained with reference to FIG.

When the ball 11 moves in the X-axis direction, the ball contact shaft 20, which is closely connected to the ball 11, rotates, which causes the rotary plate 21 to rotate, and accordingly, the contactor 22, each A terminal 24, and each The input voltage ■cc from the C terminal 26 is connected to the B terminal 25 through the contact 22, and as shown in FIG. and the voltage between each B terminal 25 is the reference voltage (E)
Appears between terminal 30 and P output terminal 27 and Q output terminal 28.

P when the double speed switch 13 is in the off state (the state shown by the broken line in Fig. 3) and in the on state (the state not shown by the solid line in Fig. 3).
The output waveforms of the output terminal 27 and the Q output terminal 28 are shown in FIGS. 4(a) and 4(b), respectively.

When the double speed switch 13 is on, the contact 22 is
Each time the terminal 24 and each B terminal 25 are contacted, an output voltage appears at the P output terminal 27 and the Q output terminal 28, resulting in the output waveform shown in FIG. 4(b), but when the double speed switch 13 is off, In the state, the contacts 22 are connected to the A terminals 24 and Bl of A3.

Only when the B terminal 25 of B3 is contacted, output voltages appear at the P output terminal 27 and the Q output terminal 28, resulting in output waveforms shown in FIG. 4(a), respectively.

That is, when the double speed switch 13 is on, it generates twice as many pulses as when it is off, and it is possible to send the same signal as when it is off with half the movement distance of the mouse device.

The above explained the operation of movement in the X-axis direction, but
The operation of the movement signal generator 3 for movement in the axial direction is also similar to that for movement in the X-axis direction.

In addition, in FIG. 4, when the ball 11 moves forward, the output waveform of the P output terminal 27 precedes the output waveform of the Q output terminal 28, and when the ball 11 moves backward, the reverse occurs, so that forward movement and backward movement are distinguished. .

〔Effect of the invention〕

As explained above, the present invention provides an adjustment means that can variably adjust the proportionality constant of an output signal proportional to the distance traveled, so that even if the amount of travel is small, the computer can receive a signal as if it had traveled a large distance. There is an effect that can be input.
