Abstract

PURPOSE:To move a cursor along a line having a certain inclination to the X axis or the Y axis by providing two converters and respective ratio switches. CONSTITUTION:When terminals 14 and 17 of an X axis signal selecting switch part 20 and terminals 15 and 18 of a Y axis signal selecting switch part 21 are connected, the cursor is operated as the normal mouse. When terminals 14 and 17 of the X axis signal selecting switch part 20 are connected and the Y axis signal selecting switch part 21 is opened, the cursor is moved along the same X-axis coordinates. When terminals 14 and 16 of the X axis signal selecting switch part 20 are connected and the Y axis signal selecting switch part 21 is opened, an X axis signal reception converter 10 generates Y axis pulses whose ratio corresponds to the value set by a ratio switch 12 to the number of pulses in the X-axis direction, and they are used as pulses in the Y-axis direction. Consequently, the cursor is moved on a line having the inclination set by the ratio switch to the X-axis direction. The same operation performed with respect to the Y-axis direction.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse device, and more particularly to its mechanical structure.

[0002]

2. Description of the Related Art A conventional mouse device is used as a simple input device for a computer.

FIG. 2 shows an example of the internal structure of a conventional mouse device. In this mouse device, a ball 2 is rotatably supported on a bottom plate 1, and an X-axis roller 4 that contacts the ball 2 and distributes the rotation direction and the number of rotations of the ball 2 in the X-axis direction and the Y-axis direction. The Y-axis roller 3 is attached.

Further, pulse generators 5 and 6 are attached to the rollers 3 and 4, respectively. Further, wirings 9 and 8 are arranged to input the signals of the pulse generators 5 and 6 to the computer.

When the mouse body is moved, the ball 2 rolls, and the rollers 4 and 3 distribute the balls 2 in the X-axis direction and the Y-axis direction according to the rotation direction and the number of rotations. Each pulse generator 6 and 5 produces | generates the pulse number according to the rotation speed.

The generated signal is input to the computer main body through the wirings 9 and 8, and the cursor performs an operation matching the signal from the mouse device on the display and matching the mouse device main body.

Further, by providing the signal selection switch 7, it is possible to select one of the X-axis signal and the Y-axis signal.

[0008]

This conventional mouse device has only the function of collectively distributing signals in the X-axis direction and the Y-axis direction or using one of the signals by a selection switch. Therefore, it is difficult to move the cursor on a straight line having a certain inclination.

Also, this makes it difficult to draw the lines without blurring them when creating a table.

An object of the present invention is to provide a mouse device in which a cursor can be easily moved on a straight line with a certain inclination.

[0011]

In order to achieve the above object, in a mouse device according to the present invention, a ball rotatably supported on a bottom plate of a main body and a ball circumscribing the ball and rotating direction and rotation of the ball. A roller that distributes the number in the X-axis direction and the Y-axis direction, a pulse generator that is connected to the roller and that generates a signal according to the rotation speed of the ball, and a selection switch that selects the signal that is generated by the pulse generator. A converter that receives a signal for the axial direction, outputs the value as it is in the X-axis direction, and outputs a signal in an amount proportional to the signal in the Y-axis direction, and a signal for the Y-axis direction. It has a converter for receiving and outputting the value as it is in the Y-axis direction while outputting the value as it is, and a switch for setting the ratio of each converter in the X-axis direction. thing A.

[0012]

By changing the ratio of the signals output in the two directions of the X axis and the Y axis, the cursor can be easily moved to a straight line having a constant inclination.
