Abstract

PURPOSE:To change the moving quantity of a cursor despite the same moving quantity of a mouse by using a magnification changing means and a variable amplifying means which changes the amplification factor of the value delivered from a moving amount detecting means in response to the output of the magnification changing means. CONSTITUTION:A switch 2 is provided at the upper face side of a box-shaped mouse main body 1 which is put on a pad 5 where the cross stripes are printed. While a pair of light transmission/reception windows 4 and a pressure sensor 6 are set on the lower face side of the body 1. Furthermore the body 1 contains a moving degree detecting circuit 7, a multiplication circuit 8 and an output interface 9. The circuit 7 receives the light beams P1 delivered from one of both windows 4 and reflected back from the cross stripes of the pad 5 through the other window 4 and detects the moving direction and degree of the mouse 1 to supply them to the circuit 8. The circuit 8 multiplies the relative coordinate value supplied to the sensor 6 from the circuit 7 by 1-3 times in response to the value of the pressure detecting signal. Thus it is possible to change the moving quantity of a cursor despite the same moving quantity of the mouse 1.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a mouse used in a computer system or the like.

<Prior Art> Mechanical mice, optical mice, and the like are conventionally known as pointing devices for computer systems and the like.

A mechanical mouse consists of a box-shaped mouse body and a rotatable ball on the bottom of the mouse body.
If you move the mouse body while this ball is in contact with a desk, etc., the ball will rotate corresponding to the amount and direction of movement, and the computer system will calculate the relative coordinate values according to the amount and direction of rotation. etc. are input.

Optical mice also have a box-shaped mouse body, a light emitter installed on the bottom side of the mouse body, and a light receiver installed alongside the light emitter. A board surface (pad) with lines drawn in a matrix pattern
When this optical mouse is placed on the mouse and moved, the amount and direction of movement are detected by the light emitting device and receiver, and the coordinate values corresponding to the amount and direction of movement are input into a computer system, etc. Ru.

<Problems to be Solved by the Invention> By the way, in such conventional mice, the ratio when converting the amount of movement of the mouse to the amount of cursor movement of the computer system is constant, so it is difficult to convert the cursor to a CRT.
There is a problem in that the amount of mouse movement increases when moving from one end to the other.

Therefore, it is possible to increase the ratio at which the amount of mouse movement is converted to the amount of cursor movement on the computer system, so that a small movement of the mouse can cause the cursor to move a large distance. When you want to make a small movement, it becomes difficult to do so.

In view of the above circumstances, the present invention makes it possible to change the amount of cursor movement even if the amount of mouse movement is the same by making the ratio variable when converting the amount of mouse movement into the amount of cursor movement of the computer system. The aim is to provide a mouse that can.

Means for Solving the Problems> In order to solve the above problems, the mouse according to the present invention has the following features:
In a mouse comprising a mouse body and a movement amount detection means for detecting the movement amount of the mouse body, a magnification changing means and an amplification factor of a value outputted by the movement amount detection means in accordance with an output of the magnification changing means. The invention is characterized in that it is equipped with variable amplification means for changing the.

<Embodiment> wc 1 (A) is a side view showing a first embodiment of a mouse according to the present invention, and FIG. 1 (B) is a bottom view of the same embodiment.

The mouse shown in these figures includes a box-shaped mouse body 1 that is placed on a band 5 on which a plaid pattern is printed, a switch 2 that is sunken on the top of the mouse body 1, and a switch 2 that connects the output of the mouse body 1 to a computer system. Code 3 to be transmitted to
, a pair of light emitting/receiving windows 4 provided on the lower surface side of the mouse body 1, and a pressure sensor 6 provided on the lower surface side of the mouse body 1;
As shown in the figure, a movement amount detection circuit 7, a multiplication circuit 8, and an output interface 9 are provided.

The movement amount detection circuit 7 receives light P1 from one side of the light emitting/receiving window 4.
When the light is emitted and reflected by the checkered pattern of the pad 5 and returned, it is received by the other side of the light emitting/receiving window 4, and the box-shaped mouse body l placed on the pad 5 is The light P1 is intermittently reflected by the vertical lines (for example, lines that reflect blue light) and horizontal lines (for example, lines that reflect infrared light) that constitute the checkered stripes of the pad 5 by being moved. When the light P2 is intermittently incident on the other light emitting/receiving window 4, the number of intermittences is counted to detect the direction and amount of movement of the mouse body 1, and the detection result (relative coordinate value) is calculated. is supplied to the multiplication circuit 8.

The multiplication circuit 8 multiplies the relative coordinate value supplied from the movement amount detection circuit 7 by 1 to 3 according to the value of the pressure detection signal of the pressure sensor 6, and the multiplication circuit 8 is configured to multiply the relative coordinate value supplied from the movement amount detection circuit 7 by 1 to 3 according to the value of the pressure detection signal. When the mouse body 1 is not pressed strongly against the pad 5, K is the relative coordinate value supplied from the movement amount detection circuit 7, and when the mouse body 1 is strongly pressed against the pad 5, the relative coordinate value supplied from the movement amount detection circuit 7 is used as is. The relative coordinate value supplied from 7 is tripled and supplied to output ink 7 ace 9.

An output interface 9 connects this mouse and a computer system (path shown), and converts the relative coordinate values supplied from the multiplication circuit 8 and the signal supplied from the switch 2 into data in a predetermined format and outputs them to the computer. supply to the system.

In this way, in this embodiment, since the amplification factor of the relative coordinate value output by the movement amount detection circuit 7 is changed depending on the pressure with which the mouse body 1 is pressed against the pad 5, the movement amount of the mouse body 1 is the same. However, with the pressure of pressing the mouse body 1 against the pad 5, it is possible to move the cursor of the computer system by a large amount or by a small amount.

FIG. 3 is a side view showing a second embodiment of the mouse according to the present invention.

The mouse shown in this figure differs from the mouse shown in FIG. 1 by removing the pressure sensor 6 from the bottom surface of the mouse body 1.
A pressure sensor S-a is attached to the side of the mouse body 1.

In this way, even if the amount of movement of the mouse body 1 is the same,
In response to the pressure applied when digging the mouse body 1, the cursor of the computer system can be moved largely or slightly.

FIG. 4 is a side view showing a third embodiment of the mouse according to the present invention.

The mouse shown in this figure is different from the mouse shown in FIG.
As shown in FIG. 5, the amplification factor of the multiplication circuit 8-3 for amplifying the relative coordinate value output by the movement amount detection circuit 7 is changed.

Therefore, by simply operating this changeover switch 12, the cursor of the computer system can be moved largely or slightly, even if the amount of movement of the mouse body 1 is the same.

<Effects of the Invention> As explained above, according to the present invention, the ratio when converting the amount of mouse movement to the amount of cursor movement of the computer system is made variable, so even if the amount of mouse movement is the same, the cursor movement is You can change the amount.
