Abstract

PROBLEM TO BE SOLVED: To provide a mouse which can decrease the dust, etc., attached to the 1st and 2nd cams. SOLUTION: A cleaner 1 is provided on a printed circuit board 3 to clear away the dust, etc., attached to a 1st cam 4 and a 2nd cam from the outside via a ball 5 together with an attachment plate 2 which is supported so as to make the cleaner 1 revolvable freely and also touch always the 1st cam 4 and the 2nd cam. When a easing 1 is held and moved, the ball 5 which is placed in a free rotatable way revolves. Accordingly, the cam 4 and the 2nd cam touching the ball 5 also revolve in each prescribed direction in response to the movements of both cams. Thus, the cleaner 1, which is touching the cam 4 and the 2nd cam also revolves to clean both cams. As a result, the dust, etc., attached to the cam 4 and the 2nd cam are cleaned away.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a mouse, and more particularly, to a mouse having a cleaning mechanism in its housing.

2. Description of the Related Art Conventionally, a mouse connected to a personal computer or the like has, as shown in FIG. 5, a ball 5 which is rotatably arranged, and a first ball 5 which rotates in contact with the ball 5 by the rotational force of the ball 5. And a second cam 4 which is rotated by the rotational force of the ball 5 in contact with the ball 5 and whose axial direction is substantially orthogonal to the axial direction of the first cam 4.
(Not shown), a first rotation angle detector (not shown) for detecting the rotation angle of the first cam 4, and a second rotation angle detection for detecting the rotation angle of the second cam 4 (Not shown), a printed circuit board 3 having a conduction pattern, and connected to the first and second rotation angle detectors;
, A second cam, a first rotation angle detection unit, a second rotation angle detection unit, and a housing 6 for housing the printed circuit board 3 and the like.
It is composed of According to the mouse having such a configuration, when the user holds and moves the housing 1, the ball 5 that is rotatably disposed rotates. Then, the first cam 4 and the second cam which are in contact with the ball 5 also rotate in a predetermined direction according to the movement. This first cam 4 and the second cam
The first and second rotation angle detectors take out the rotation direction and rotation angle of the cam as coordinate data signals of the respective components in the X-axis direction and the Y-axis direction, and input the signals to a monitor (not shown). Freely move the cursor displayed in.

However, in the above-mentioned conventional mouse, the ball easily adheres to the dust and the like, so that the dust and the like also adhere to the first and second cams in contact with the ball. When dust or the like adheres to the first and second cams, the coefficient of friction with the ball is reduced, and the rotation of the first and second cams is hindered. There has been a problem that the first and second cams must be frequently cleaned because they become worse. Therefore, an object of the present invention is to provide a mouse that can reduce dust and the like adhering to the first and second cams.

SUMMARY OF THE INVENTION Accordingly, in order to achieve this object, the present invention provides a ball which is rotatably arranged, a first cam which is in contact with the ball and which is rotated by the rotational force of the ball, and A second cam arranged in such a manner that the second cam rotates in contact with the ball by the rotational force of the ball and has an axial direction substantially orthogonal to the axial direction of the first cam; and a first rotation for detecting a rotation angle of the first cam. An angle detector, a second rotation angle detector for detecting a rotation angle of the second cam, a printed circuit board having a conduction pattern and connected to the first and second rotation angle detectors, A first housing, a first cam, a second cam, a first rotation angle detector, a second rotation angle detector, and a housing for accommodating a printed circuit board. Cleaner that removes dust and the like adhering to Over Na is rotatable and the first
And a mounting plate supported so as to be always in contact with the second cam is provided inside the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a mouse according to the present invention will be described below with reference to the drawings. FIG.
FIG. 2 is a cross-sectional view showing one embodiment of the mouse according to the present invention, and FIG. 2 is a perspective view of a main part of the cleaner and the mounting plate of FIG.
The same parts as those of the conventional example shown in FIG. 5 are denoted by the same reference numerals, and detailed description thereof will be omitted. The feature of this embodiment is that a cleaner 1 for removing dust and the like adhering to the first cam 4 from outside via a ball 5 and the cleaner 1 is rotatable and always in contact with the first cam 4. The mounting plate 2 supported in this manner is provided. The cleaner 1 is formed of metal or resin, and has, for example, a cylindrical shape. The mounting plate 2 on which the cleaner 1 is rotatably supported is fixed on, for example, a printed circuit board 3.
Note that a cleaner having the same structure is provided on the second cam (not shown) so as to be in contact with the second cam and supported by the mounting plate. According to the embodiment, when the housing 1 is moved while being held, the ball 5 that is rotatably arranged rotates. Then, the first cam 4 and the second cam which are in contact with the ball 5 also rotate in a predetermined direction according to the movement. Along with this, the cleaner 1 in contact with the first cam 4 and the second cam respectively also rotates, and the first cam 4
Then, the second cam is cleaned, and if dust or the like adheres to the first cam 4 and the second cam, it is removed. As described above, in the mouse according to the present embodiment, the cleaner 1 is always in contact with the first cam 4 and the second cam, and the first and second cams can be cleaned by using the mouse. Dust and the like adhering to the first and second cams can be reduced. Further, the cleaner 1 and the mounting plate 2 are mounted on the printed circuit board 3, but may be located anywhere in the housing 6 as long as the first and second cams can be cleaned. In the above-described embodiment, a structure in which the columnar cleaner 1 is supported by the mounting plate 2 is used, but a structure having the structure shown in FIGS. 3 and 4 may be used. That is, the cleaner 11 has a plate shape.
The center part of the cleaner 11 is supported by the mounting plate 12 so that one end of the cleaner 11 contacts the first cam 4 and the second cam.
The other end and the printed circuit board 3 are first
Alternatively, the contact force between the second cam and the cleaner 11 may be adjusted and fixed. Even in such a configuration, dust and the like adhering to the first and second cams can be reduced.

As described above, according to the present invention,
Since the cleaner is always in contact with the first and second cams and the first and second cams can be cleaned by using a mouse, dust and the like attached to the first and second cams are reduced,
The number of steps for cleaning the inside of the mouse can be reduced or reduced.
