Abstract

PURPOSE:To stop a cursor at an accurate stop position by switching the ratio between the shift distance of a mouth and that of a cursor in order to quickly shaft the cursor or to attain fine adjustment of the cursor. CONSTITUTION:A keyboard 26 is operated to set previously a shift ratio between the ON and OFF modes of a resolution setting switch 5 of a mouth 1. When said shift ratio is set at 1:1, for example, a cursor moves on a screen by a distance equal to the shift distance of the mouth 1. While the cursor moves by a 1/5 distance of the mouth 1 when said ratio is set at 1:5. When the mouth 1 is used, the switch 5 is first turned off to shift the cursor up to a place near the prescribed position. Then the switch 5 is turned on to shift the cursor accurately to the prescribed position. Then the desired commands are supplied by means of input switches 2 and 3 or the keyboard 26.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a cursor movement data manual device (hereinafter referred to as a mouse) for moving a cursor displayed on a screen of a data processing device or the like.

(b) Summary of the Invention The mouse according to the present invention is provided with a resolution setting switch that changes the ratio of the moving distance of the cursor on the screen to the moving distance on the flat plate.

(0) Conventional technology and its disadvantages When a mouse is moved on a flat plate such as a desk, a rotor in contact with the desk rotates, and the rotation is decomposed into an X coordinate and an X coordinate, converted into pulses, and output. be. The ratio between the distance the mouse moves and the distance the cursor moves on the screen (hereinafter referred to as the "movement ratio") can be set using a command.
When moving the cursor over a large distance, for example, by setting it to tri, the cursor moves a distance equal to the moving distance of the mouse, so the cursor can be moved quickly. Furthermore, if the ratio is set to 5:1, the cursor can be moved delicately with the mouse, and the cursor position can be determined accurately. In order to use the mouse efficiently, it is desirable to be able to convert the above ratios with simple operations, but conventionally, in order to convert this ratio, it was necessary to operate the keyboard and input commands each time. Ta.

fd+ OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a mouse that can change the ratio between the moving distance of the mouse and the moving distance of a cursor using a changeover switch attached to the mouse.

(θ) Structure and Effect of the Invention The present invention includes a resolution setting switch that sets the ratio between the moving distance on the flat plate and the moving distance of the cursor, and outputs movement ratio data by the resolution setting switch in addition to the cursor movement data. or an output device that outputs cursor movement data including a cursor movement distance according to a ratio of movement distances set by the resolution setting switch.

With the above configuration, the following effects can be achieved according to the present invention.

By setting multiple movement ratios appropriately (for example, 1:5 and 1:1) and assigning each to the on/off time of the resolution setting switch, you can quickly turn off the resolution setting switch and move the cursor to the target position. , turn on the resolution setting switch, and fine-tune the cursor position to make it stop at an accurate stop position. This makes it possible to efficiently operate the data processing device that processes data etc. by operating the cursor on the display screen (f)
Embodiment FIG. 2 is an external view of a mouse that is an embodiment of the present invention. This mouse 1 has a rotor on the back (not shown), and is operated by rotating it on a flat plate such as a desk. A command person Kasuinochi 2.3 is attached to the top surface of the mouse 1, and a resolution setting switch 5 is installed on the side at a position opposite to the thumb when the mouse 1 is operated with the right hand.

4 is a cord connected to the data processing device.

FIG. 1 is a block diagram of the control section of the above embodiment. The X-direction encoder 6 and the Y-direction encoder 8, which decompose the rotation of the rotor into the X-axis and Y-axis directions and convert them into pulses, are each connected to a pulse counter 7.9, and these pulse counters 7.9 are connected to 110 ports 12. 13 to the bus. This bus includes the command manual switch 2,
31 resolution setting switch 5 is connected via I10 boat 14, CPUI O5RAM15, RO
M11 and a parallel/serial converter 16 are connected. The CPU 10 reads manually input data from the I10 board 12, 13, and 14, and appropriately outputs cursor movement data via the parallel/serial converter 16 to the microcomputer to which the mouse 1 is connected. R.O.
The MII stores a program for performing this processing, and the RAM 15 temporarily stores data and provides a work area necessary for executing the program.

FIG. 3 is a block diagram of a data processing device using the above embodiment. The processing CPU 17 is connected to a CRT via a bus.
Controller 18, memory management unit 22
, a disk memory 23, and an interface 24 are connected. The memory management unit 22 has an RA
An internal memory 21 consisting of M and ROM is connected. A CRT controller 18 controls a display memory 19 consisting of a video RAM.
The contents of 9 are displayed on a CRT 20 connected to this display memory 19. A 1,000-knob microcomputer 25 for human output control is connected to the interface 24, and this 1-chip microcomputer 25 controls data input from the keyboard 26 and the mouse 1 which is an embodiment of the present invention.

When using the data processing device with the above configuration, first operate the keyboard 26 to select the resolution setting switch 5 of the mouse 1.
The respective movement ratios for on/off times are set in advance.

For example, if the moving ratio is set to 1:1 when the resolution setting switch 5 is off, the cursor will move on the screen a distance equal to the moving distance of the mouse 1. If the CRT is of normal thickness, a sufficiently fast moving speed can be obtained with this moving ratio. Furthermore, if the on state of the resolution setting switch 5 is set to 1:5, the cursor moves a distance of 115 times the moving distance of the mouse 1.

When using the mouse 1, first turn off the resolution setting switch 5 to move the cursor to a predetermined position.Turn on the zero-order resolution setting switch 5 to move the cursor to a predetermined position accurately. Thereafter, data processing is performed by inputting necessary commands by operating the command input switch 2.3 or the keyboard 26.

The moving distance of the mouse l is determined by the number of pulses output by the pulse encoder 6.8 in the X and Y directions.
9 to count and measure, but the calculation to calculate the moving distance of the cursor by multiplying the moving distance and the moving ratio is in Mouse 1.
The calculation result may be output to the data processing device as cursor movement data, or the count value of the pulse counter 7.9 and the movement ratio may be directly used as cursor movement data to the data processing device. The cursor movement distance may be calculated by the single-chip microcomputer 25 by outputting the data to the 1-chip microcomputer 25.

As described above, if the movement ratio of the cursor and the mouse 1 is set in advance to a plurality of appropriate ratios, and the cursor is moved using the mouse 1 while switching between these ratios by operating the resolution setting switch 5, efficient Can perform data processing.
