Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse controller having a mechanism for transmitting the rotation of a ball rollable on an operation surface to a shaft via a roller.

[0002]

2. Description of the Related Art Conventionally, in a mouse controller having a mechanism for transmitting the rotation of a ball that can roll on an operation surface to a shaft via a roller, dust adheres to the roller during use. As a result, the operability deteriorates.
It was necessary to remove trash regularly. As a technique for solving this, there is a technique described in Japanese Patent Application Laid-Open No. Hei 8-152965.

[0003]

In the above prior art,
A dust removing device for removing dust attached to the roller is provided inside. However, there was still a problem that the mouse controller had to be periodically disassembled in order to clean the dust removing device.

The present invention provides a mouse controller in which dust does not adhere to the rollers, thereby eliminating the trouble of periodically disassembling the mouse controller and improving the user's convenience.

[0005]

A mouse controller according to the present invention has a mechanism for transmitting the rotation of a ball rollable on an operation surface to a shaft through a roller inside a main body mainly made of a plastic material. Have. By providing a groove in the roller, dust is prevented from adhering to the roller, and the operability of the mouse controller is improved. Furthermore, since dust does not adhere to the roller, the user does not have to periodically remove dust from the mouse, thereby improving convenience for the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The mouse controller of the present invention
The rotation of the ball that can roll on the operation surface is transmitted to the shaft via a roller that detects the component as a component in the direction orthogonal to the shaft inside the main body mainly made of plastic material, and the amount of rotation is converted into a distance signal. It has a mechanical mechanism that transmits the moving direction and distance to a computer by a rotary encoder. The roller is provided with a groove so that dust adhered to the ball does not adhere to the roller by operating the mouse controller on the operation surface.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the overall structure of a mouse controller of the present invention, FIG. 2 is a front view of a conventional internal mechanism of the mouse controller, and FIG. 3 is a front view of the internal mechanism of the mouse controller of the present invention.

Referring to FIG. 1, the overall structure of the mouse controller of the present invention will be described. Inside the main body 1, a ball 2 that rotates according to the amount of movement of the main body 1, a roller 3 that comes into contact with the ball 2 and detects the amount of rotation of the ball 2 as a component in the orthogonal direction, and dust on the roller 3 And a rotary encoder 5 for converting the amount of rotation of the groove 4 into a distance signal.

Referring to FIG. 2, a conventional mouse controller having no groove will be described. With the conventional roller 6 having no groove, the dust 7 adhered to the roller 6 was formed by operating the mouse controller on the operation surface so that the dust 7 attached to the ball 2 was pressed against the roller 6. Was. Further, the dust 7 adhered to the roller 6 makes the dust 7 more easily adhered, and eventually adheres to the roller 6 like a strip-shaped dust 8. for that reason,
The operability of the mouse controller was poor. Therefore,
The roller 6 is provided with the groove 4 like the roller 3 in FIG. 1, and this configuration makes it possible to reduce adhesion of dust to the roller.

Referring to FIG. 3, the roller 3 of the mouse controller according to the present invention will be described. In this embodiment, a groove 4 is provided in the roller 3. Therefore, the roller 3 comes into contact with the ball 2 at two points.

The shape of the groove 4 will be described below with reference to FIG. The groove depth 11 must be such that the ball does not contact the shaft of the roller 3. If the contact has occurred, a belt-like dust 8 is applied to the contact portion in the same manner as the conventional roller 6.
Is attached. Therefore, the gap between the ball and the shaft of the roller 3 is preferably 0.75 mm or more. In addition, as the angle θ9 between the ball and the roller is closer to 45 degrees, dust is less likely to adhere to the edge of the groove.
It is preferable that the temperature be equal to or higher. Under these conditions, the optimum shape of the groove 4 was examined, and the groove depth 11 = D
× 0.03 + 0.75, groove width 10 = D × 0.034. Also, groove 4
Needs to be provided over the entire circumference of the roller 3 because the roller 3 rotates.

By providing such a groove 4 in the roller 3, with such a configuration, dust 7 is scraped into the groove 4 without adhering to the roller 3 at a portion where the ball 2 and the roller 3 are in contact. It is. Therefore, dust 7
Can be prevented from continuing to adhere, and the operability of the mouse controller can be prevented from being impaired.

In this embodiment, one groove 4 is formed in the roller 3.
However, it goes without saying that a plurality of grooves may be provided.

[0014]

According to the present invention, the adhesion of dust on the roller portion of the mouse controller can be reduced, and the operability of the mouse controller and the convenience of the user can be improved.
