Abstract

PURPOSE: To easily remove dust sticking on a ball without deteriorating the slidability of the ball by fitting a brush so that it can come into contact with the entire peripheral edge of the ball. CONSTITUTION: On the bottom surface of a mouse main body, a ball stop member 3 which receives the ball is provided. This ball stop member 3 can be detached from the main body by being slid toward a triangular mark given to a display part where OPEN is displayed. The brush 4 for dust sticking prevention is fitted by implantation or adhesion over the entire circumferential surface of a cylindrical member 32 formed into a ring shape along the hole 31 of this ball stop member 3. Thus, the tip of the brush 4 is brought into contact with the entire peripheral edge of the ball and then dust sticking on the ball is removed by the brush 4. The brush part of this brush is 2-4mm long and preferably uses a material which is soft and elastic like horse hair and causes no friction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse, and more particularly to a mouse which is a pointing device used in an information processing apparatus such as a workstation and a personal computer.

[0002]

2. Description of the Related Art In this type of mouse, an operator moves one ball on a plane to rotate a ball at the bottom, detects the amount and direction of rotation of the ball, and displays the detected information on a display screen. It is used as position information of the cursor.

As described above, the mouse is required to be dust-proof because it is used by moving it on a plane. Therefore, Japanese Utility Model Laid-Open No. 4-20135 discloses a technique for preventing dust from entering the gap between the mouse body and the ball by attaching a dust removing member to the lower peripheral edge portion of the side surface of the mouse.

Further, in Japanese Utility Model Laid-Open No. 5-30945,
The bottom of the mouse body is equipped with a dust-collecting plate with a large dust-collecting cloth attached to it so that it can be absorbed by the dust-collecting plate before it reaches the mouse ball. Prevents dust from directly adhering to the ball,
A technique for preventing the ball from entering the inside of the mouse is disclosed.

[0005]

[Problems to be Solved by the Invention]
In the configuration disclosed in the publication, since the dust removing member is attached to the lower peripheral portion of the side surface of the mouse, there is a problem that the ball slips poorly. Also, the actual Kaihei 5-30
In the structure of Japanese Patent No. 945, since the dust collecting plate is attached to the bottom surface of the main body, the frictional force becomes extremely large due to the contact surface between the dust collecting plate and the desk surface, and the slip of the ball is extremely bad. .

If the frictional force between the dust-collecting member and the desk surface is large, the ball will rise and fall so much that the operator cannot smoothly move the cursor to the desired position. There is also a problem that the movement of the cursor becomes irregular, the operability is poor, and the operator mistakenly recognizes that the mouse is broken.

An object of the present invention is to provide a mouse capable of easily removing dust attached to a ball without deteriorating the sliding condition of the ball.

[0008]

The mouse according to the present invention comprises:
It is characterized by including a ball and a brush for preventing the attachment of dust particles provided in contact with the ball.

[0009]

The brush is brought into contact with the entire periphery of the ball, and the dust is always removed by the brush as the ball rotates, effectively preventing the dust from entering the inside of the main body.

[0010]

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

First, referring to FIG. 1, there is shown a back view (bottom view) of a general mouse, and a ball stopper member 3 for receiving a ball 2 is provided on the bottom surface of a mouse body 1. The ball stopping member 3 is configured to be disengaged from the main body 1 by sliding it in the direction of the triangle marked on the display unit 31 labeled "OPEN". Is.

FIG. 2 is a perspective view showing a state in which the ball stopping member 3 in the embodiment of the present invention is detached from the main body,
The back surface of the ball stopping member 3 is shown as desired. As shown in the figure, the dust adhesion preventing brush 4 is attached or attached by gluing over the entire inner peripheral surface of the cylindrical member 32 formed in a ring shape along the hole 31 of the ball stopping member 3.

In this way, by making the tip of the brush 4 contact along the entire peripheral edge of the ball 2, the ball 3
The attached dust will be removed by brushing.

The length of the brush portion of the brush 4 is 2 to 4 mm, and it is preferable that the material of the brush 4 is soft and elastic like horse hair, and does not generate frictional force.

By doing so, the dust attached to the ball is constantly wiped off by the brush, so that the dust enters the main body to the rollers etc. as compared with the case where the brush is not attached to the back side of the ball stopper. No more wrapping around. By providing a brush on the back side of the ball stopper and selecting a soft, elastic, and small frictional force, the slip of the ball will be the same as before.

[0016]

As described above, according to the present invention, since the brush is attached so as to be able to contact along the entire periphery of the ball, it is possible to prevent the attachment of dust without impairing the slip of the ball. .
