Abstract

PURPOSE:To change the moving amount of a cursor on a display screen with the pressing pressure of a mouse device against a table by forming a transmitting shaft to the form of a rotating body other than cylinders around a rotating axis and making the position of the point at which the shaft is brought into contact with a ball variable in accordance with the pressing pressure. CONSTITUTION:A transmitting shaft 2 is formed to the shape of a rotating body other then cylinders around a rotating axis and the position of the point at which the shaft 2 is brought into contact with a ball 1 is made variable in the direction other than the rolling direction of the shaft 2 in accordance with the pressing pressure of a mouse device against a table. Accordingly, when the pressing pressure of the mouse device against the table changes, the rolling diameter of the shaft 2 around the rotating axis at the point at which the shaft 2 is in contact with the ball 1 changes. Therefore, the moving amount of a cursor on a display screen can be made variable against the unit moving amount of the mouse device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mouse device for a personal computer or the like.

[Conventional technology]

As a method of varying the amount of cursor movement on a display screen with respect to a unit movement amount of a conventional mouse device, as described in Japanese Patent Application Laid-open No. 172326/1982, the amount of cursor movement is varied according to the movement speed of the mouse device. There is a way to operate.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, it is necessary to measure the moving speed of the mouse device, and the program for the mouse device must be additionally changed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mouse device that allows the amount of cursor movement on a display screen to be varied with respect to the unit movement amount of the mouse device without additionally changing the mouse device program.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a ball that can roll on a tabletop, a transmission shaft that contacts the ball and rotates around the rotation axis as the ball rotates, and a transmission shaft that rotates around the rotation axis as the ball rotates. an encoder that generates a movement signal according to an amount of rotation, and a mouse device that moves a cursor on a display screen according to the movement signal generated by the encoder, wherein the transmission axis is centered around the rotation axis. a rotating body other than a cylindrical shape, and the position of the contact point with the ball moves in a direction other than the direction around the axis of rotation in response to the pressing pressure of the mouse position on the table. Made it possible to change.

[Effect]

The shape of the transmission shaft is a rotating body shape other than a cylindrical shape centered on the rotating shaft. The position of the contact point of the transmission shaft with the ball changes in a direction other than the direction around the rotating shaft in response to the pressing force of the mouse device on the console. Therefore, when the pressing force of the mouse device on the desk changes, the diameter around the axis of the rotating shaft at the contact portion of the transmission shaft with the city ball changes.

On the other hand, what is the movement signal generation mechanism of the mouse device?

It looks like this: That is, the amount of movement of the ball, which is the amount of movement of the mouse device, is converted into the amount of rotation of the transmission shaft, and the amount of rotation of the transmission shaft is further converted into a movement signal by an encoder.

Therefore, when the diameter around the shaft of the rotating shaft at the contact portion of the transmission shaft with the ball changes, the amount of rotation of the transmission shaft relative to the unit movement of the ball changes, and therefore the movement signal changes as well. do.

Therefore, according to the present invention, by changing the pressing force of the mouse device on the console, it is possible to change the amount of movement of the cursor on the display screen relative to the unit movement amount of the mouse device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1(a) is a plan view showing a mouse device as an embodiment of the present invention when the pressing force on the desk is small, and FIG. 1(b) is a plan view showing the 11 directions of FIG. 2(a) is a sectional view showing the cross section, and FIG. 2(a) is a plan view showing the mouse device of FIG.
b) is a sectional view showing the cross section in the II direction of FIG. 2(a),
It is.

In the figure, 1 is a ball that rotates on the rear table 7 as the mouse device moves, 2 is a conical transmission shaft that contacts the ball 1 and transmits the rotation of the ball 1 to an encoder 4, which will be described later, and 3 is a transmission shaft. 2 and an encoder 4 to be described later, 4 is an encoder that generates a movement signal, 5 is a presser roller that presses the ball 4 against the transmission shaft, 6 is a bottom plate, and 7 is a mouse device. It is a table.

Next, the operation will be explained.

When the pressing force of the mouse device on the console 7 is small, as shown in Fig. 1 (
As shown in a) and (b), universal joint 3
Although the distance between the encoder 4 and the transmission shaft 1 becomes shorter due to the tensile force, the positional relationship between the encoder 4 and the ball 1 is always constant, so the diameter of the portion where the transmission shaft 2 contacts the ball 1 becomes larger.

On the other hand, when the pressing force on the mouse device r; However, since the positional relationship between the encoder 4 and the ball 1 is always constant, the diameter of the portion where the transmission shaft 2 contacts the ball becomes small.

In addition, in FIG. 1(a) and FIG. 2(a), the transmission shaft 2
Since the internal angle α of the tangent between the ball 1 and the ball 1 is 90 degrees, the internal angle β of the center line of the conical transmission shaft 2 is not 90 degrees.

As mentioned above, the mouse device J? By applying pressure to the ball 17, the diameter of the contact portion of the transmission shaft 2 with the ball 1 can be changed. That is, from ball 1 to encoder 4
The mechanical transmission coefficient up to can be changed depending on the pressure applied to the table 7.

Therefore, according to the present embodiment, when the pressure on the desk 7 is large, the amount of movement of the cursor on the display screen relative to the unit movement amount of the mouse device can be made larger than when it is small.

In this embodiment, the shape of the transmission shaft 2 is conical, but the present invention is not limited to this.

Any rotating body shape other than a cylindrical shape, such as an elliptical spherical shape, is sufficient.

〔Effect of the invention〕

According to the present invention, the amount of movement of the cursor on the display screen relative to the unit amount of movement of the mouse device can be varied by the pressure of the mouse device on the desk, without additionally changing the program for the mouse device.
