Abstract

PURPOSE:To improve the operability of a mouse by using a circuit which varies the number of output pulses to the shift value of the mouse to vary the shift value of a cursor and therefore changing the sensitivity of the mouse via a changeover switch during the application of the mouse. CONSTITUTION:A sensor part 1 always the fixed number of pulses in accordance with the shift value of a mouse. A switch 3 is usually kept at the side (a) and the pulses of the part 1 are sent to a signal line 4 as they are. When a user wants a fine shift of a cursor, the user changes the switch 3 to the side (b). Thus a dividing circuit 2 receives the number of pulses sent from the part 1 and outputs one pulse to the line 4. As a result, the shift value of the cursor is smaller on a screen than that obtained when the switch 3 is kept at the side (a) despite the shift value equal to that of the mouse. Thus the fine operations of the cursor are facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mouse as a pointing device, which is a device for inputting coordinates into a computer.

[Conventional technology]

A mouse is a device that is moved by a person on a desk, detects the amount of movement, and inputs coordinates into a computer. Depending on the method of detecting the amount of movement, it is classified into mechanical, optical, etc., but all methods transmit the amount of movement to the computer by outputting a number of pulses corresponding to the amount of movement. FIG. 3 is a schematic diagram of the optical mouse, and FIG. 4 is an enlarged view of its sensor section. 10 is mouse, 11.15
is a grid pad, 12 is a signal line to the interface section, 1
3 is a light emitting section, and 14 is a light receiving section. A mouse normally detects and outputs two-dimensional movements in the X and X directions individually, but since the detection and output methods are exactly the same in both directions, the following explanation will be given only in one direction. The grating pad 15 has light reflecting parts (bright parts) and light absorbing parts (dark parts) arranged in a grid pattern, and the light from the light emitting part 13 is reflected or absorbed on the grating pad 15 and reaches the light receiving part 14. reach. Now, when the mouse lO is moved by a certain distance on the grid pad 11, the sensor section of the mouse will pass through the bright and dark areas of the grid pad 15 by the number of times corresponding to the amount of movement.
As a result, a number of pulses proportional to the amount of mouse movement is output to the signal line 12 to the interface section. Therefore, the number of output pulses relative to the amount of movement is determined by the resolution of the sensor unit and the grid spacing of the grid pads, and cannot be varied on the mouse.

[Problem that the invention seeks to solve]

In the conventional mouse described above, the number of output pulses relative to the amount of movement of the mouse is determined in advance by hardware.

When moving a cursor on a computer screen, the cursor moves according to the movement of the mouse, but with conventional mice, the amount of cursor movement relative to the amount of mouse movement is always constant, so if you want to move the cursor subtly, - It becomes very difficult to operate when you want to make large movements at once. To solve this problem, some software allows you to change the amount of cursor movement relative to the amount of mouse movement, but not all software has this function, and even if it does have this function, it is difficult to switch modes. These operations are complicated and complicated.

[Differences between the invention and the prior art]

The mouse of the present invention differs from the conventional mouse described above in that it has a circuit for varying the number of output pulses relative to the amount of mouse movement, and the sensitivity of the mouse can be changed by a switch during use. have

[Means for solving problems]

The mouse of the present invention includes a circuit for varying the number of output pulses relative to the amount of movement, and a switch for changing the sensitivity of the mouse during use using the circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

1 is a sensor section, 2 is a frequency dividing circuit, 3 is a sensitivity changeover switch, and 4 is a signal line to an interface section. The sensor unit 1 always outputs a fixed number of pulses depending on the amount of movement of the mouse. The frequency dividing circuit 2 outputs one pulse when several pulses are input.

The switch 3 is a switch for switching between outputting the pulses output from the sensor section to the signal line 4 as is or outputting them through the frequency dividing circuit 2. Normally, the switch 3 is on the a side, and the pulses from the sensor section 1 are output as they are to the signal line 4. Now, suppose that the user switches the switch 3 to the b side if he wants to move the cursor delicately. The frequency dividing circuit 2 receives several pulses output from the sensor section 1 and outputs one pulse to the signal line 4, so even if the mouse is moved by the same amount, the movement of the cursor on the screen is controlled by switch 3. It is smaller than when it is on the side, making delicate operations easier.

FIG. 2 is a block diagram of another embodiment of the invention.

5 is a sensor section, 6 is a pulse generator, 7 is a pulse output control section, 8 is a sensitivity changeover switch, and 9 is a signal line to the interface section. The pulse generator 6 normally generates pulses with a shorter period than the pulses generated when the user moves the mouse at high speed. The pulse output control section 7 outputs the pulse from the pulse generator 6 to the signal line 9 for a certain period of time in response to the rising edge of the pulse from the sensor section 5. If the user wants to move the cursor largely at once, he switches the switch 8 to the b side. Since the pulse output control section 7 outputs several pulses to the signal line 9 in response to one pulse from the sensor section 5, as a result, the signal line 9 receives a larger number of pulses than the sensor section 5 outputs. Pulses are output and the cursor on the screen can be moved significantly.

〔Effect of the invention〕

As explained above, the present invention has the effect of improving operability by having a circuit for varying the number of output pulses with respect to the amount of movement of the mouse, so that the sensitivity of the mouse can be changed by a switch during use. be.
