Abstract

PURPOSE:To facilitate the input operations with a radio mouse by adding a switch into the mouse main body to detect the mouse pressing force and varying the shift rate of a cursor after detecting both the pressing force and the shift value of the mouse. CONSTITUTION:A base part 1 of a radio mouse includes an encoder part 2 for X and Y axes and the magnifying power switches 3a and 3b together with the A and B switches 4a and 4b set on the part 2. A mouse upper surface 5 touches both switches 3a and 3b via the projecting parts 5a and 5b formed on the rear surface of the mouse. Then the switches 4a and 4b are applied to a microcomputer 12 with the switches 3a and 3b applied to the X and Y axis encoders 10 and 11 respectively. The microcomputer 12 converts the pulses of the encoders into the serial signals added with the header signals, etc., and supplies those converted pulses to a radio transmission part 15 with the radio output sent to an antenna 16. In this case, the switches 3a and 3b work with the increase of the pressing force and the appropriate magnifying power is set for the number of pulses.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coordinate input device (hereinafter referred to as "coordinate input device") which indicates a menu or command output on a CRT screen of a computer using a cursor or an arrow, and gives commands to a computer. Regarding the mouse.

[Summary of the invention]

It has a multiplier that digitally or analogously varies the magnification of the frequency output by the X-axis and Y-axis encoders that measure the amount of mouse movement, and even if the amount of movement is the same, the magnification of the amount of movement can be changed by pressing the mouse. If the pressing force is strong, large movements can be made on the CRT screen with a small amount of movement, so the mouse can be used effectively even on a narrow disk space, for example.

[Conventional technology]

Generally, the amount of movement or magnification of the mouse is fixed, and the mouse is often moved several times on the desk. Even if it had a means to arbitrarily change the magnification, it was necessary to interrupt the work to set it on the console, and it was generally done at a constant magnification.

[Problem that the invention seeks to solve]

However, due to problems with the computer software, moving the mouse would often end up at the edge of the desk, requiring the user to lift the mouse and move it to a new position.

Particularly when operating in a narrow space, the frequency of this movement tends to increase.

On the other hand, it is desirable to be able to quickly set or change any magnification. However, providing a variety of buttons on a mouse can also cause the mouse to lose its simplicity.
Boat fishing remained as it was, as there were problems such as complicating operations, resulting in incorrect operations, and correlation with other mouse operations.

[Means for solving problems]

In order to arbitrarily change the mouse movement magnification, the present invention has the following steps:
A switch inside the mouse that detects vertical movement, which can be performed simply by pressing the mouse downward, or
A built-in potentiometer can be used to capture the movement of the mouse epithelium, and a microcomputer can memorize the pulses or frequency output from the X-axis or Y-axis encoder, and output that value as is. The magnification changes depending on whether the output is divided or multiplied.

(Function) The wireless mouse of the present invention has a switch or potentiometer in the mouse body that detects the force with which the mouse is pressed, and can detect the relationship between the pressing force and the amount of movement, thereby establishing the relationship between the pressing force and the amount of movement. This allows you to vary the movement ratio of the cursor or arrow displayed on the CRT screen.
Even in a small space on a desk, you can work more than on a wide desk.

On the other hand, as another example of the relationship between the pressing force and the amount of movement, the amount of movement ÷
It is also possible to use a pressing force.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of a wireless mouse according to an embodiment of the present invention. FIG. 2 is a block diagram showing the equipment configuration of a wireless mouse according to an embodiment of the present invention. FIG. 3 is a block diagram of a wireless mouse potentiometer according to an embodiment of the present invention.

A base section 1 in FIG. 1 is provided with an X-axis and Y-axis encoder section 2 and magnification switches 3a and 3b. At the top of the encoder section 2, A and B switches 4a and 4b are provided. Further, although the circuit board is not shown, it is housed in an empty space. Furthermore, mouse epithelium 5 is
Magnification switch 3a via convex portions 5a and 5b provided on the back surface.

3b, respectively.

Here, when the mouse epithelium 5 is pushed down, the magnification switches 3a and 3b are turned on and off.

In another embodiment, a potentiometer may be arranged in place of the magnification switches 3a and 3b to linearly detect the pressing force.

The structures in FIG. 2 that are the same as the numbers in FIG. 1 are the same. Switches A and B in FIG. 2 4a and 4b are respectively a 0 magnification switch 3a and a
3b is connected in parallel to the microcomputer 12
has been entered.

The X-axis encoder 10 and Y-axis encoder 11t+ are each input to the microcomputer.

One end of each switch or encoder is connected to the power supply of the microcomputer 12 and the emitter of the transistor 14, and the positive pole of the battery 13.

When the pressing force on the mouse epithelium 5 is a certain yield force and the magnification switches 3a and 3b are not activated, the X-axis and Y-axis
A microcomputer converts the number of pulses of the axial encoder into a serial signal with an appropriate header signal added thereto, inputs it to a wireless transmitter 15, and outputs a wireless output to an antenna 16.

At this time, it will be a mouse with a normal movement ratio,
When increasing the pressing force, use the magnification switch 3a.

3b operates and sends its output to the microcomputer 12.
When detected, the number of pulses of the X-axis and Y-axis encoders 10 and 11 are multiplied appropriately, a header signal and the like are similarly added, and the signal is converted into a serial signal and output wirelessly.

Note that the wireless output unit power source is turned ON when the output of a switch or encoder changes, and is turned OFF when wireless output ends.

〔Effect of the invention〕

In this way, if you want to change the magnification when working with a regular mouse, you can change the magnification by just applying a slight pressing force, so even a small amount of movement can cause a large amount of movement on a CRT screen. It is something that can be obtained in quantity.

As explained above, the magnification can be changed quite naturally without the need for a special switch on the surface of the mouse, which not only allows for faster manual computer work, but also reduces operator fatigue as the amount of movement of the mouse is small. I'll have to wait a while.

Furthermore, it requires only a fraction of the space that was conventionally required, so there is an advantage of space saving.

Also, you can separately reduce the magnification by adjusting the pressing force, so
Such applications can be considered in input work for computer graphics, etc.
