Abstract

(57) [Abstract] [Purpose] The present invention relates to a mouse used as a coordinate input device for a computer. Even if a horizontal mouse operation surface cannot be secured in the work space, the vertical surface can be used for operation. To do. [Structure] A ball 2 protruding from a bottom surface portion 11 of a mouse body 1 and rotating in response to movement is composed of a magnetic ball 21, and is brought into close contact with an operation surface by magnetic force.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mouse used as a coordinate input device for instructing coordinates on a display in a computer.

As a coordinate input device of a computer, a mouse that moves on a horizontal operation surface of a desk or the like and converts the movement amount into coordinates is used. In recent years, a portable small computer has become popular. As a result, the places where computers are used may be diversified, and it may not be possible to secure the horizontal surface necessary for mouse operation. In such a situation, there is a demand for a mouse that can reliably move the ball of the mouse even when it is not on a horizontal plane to input data.

[0003]

[Prior art]

 2. Description of the Related Art Conventionally, a mouse used as a coordinate input device has, as shown in FIG. 2, a part of a ball 20 formed by coating a surface of a core material such as a steel ball with synthetic rubber or the like on a bottom surface portion 11 of a mouse body 1. When the mouse body 1 is moved, the friction of the surface of the ball 20 is brought into close contact with the surface of the operation surface 3 due to the weight of the ball 20 while being placed on the horizontal operation surface 3. The ball 20 is rotated by force, and the rotation amount and direction are detected by the roller 12 in the mouse body 1 to input coordinates.

[0004]

[Problems to be solved by the device]

 However, in the conventional configuration, the surface of the ball 20 needs to be brought into close contact with the operation surface 3 due to the weight of the ball 20, so that when the operation surface 3 is a vertical surface or a steep inclined surface as shown in FIG. Since the own weight does not work on the operation surface 3 side and the close contact effect is not sufficient, and the ball 20 slides with respect to the movement of the mouse body 1 and an accurate movement amount cannot be detected, a horizontal operation surface 3 can be formed. There was a problem that the use was limited to places with space.

Therefore, an object of the present invention is to provide a mouse capable of inputting coordinates even if the operation surface is a steep inclined surface or a vertical surface.

[0006]

[Means for Solving the Problems]

 The above-mentioned object is characterized in that the ball 2 is used as a magnetic ball 21 in a mouse for inputting coordinates of a computer according to the rotational movement amount of the ball 2 protruding on the bottom surface portion 11 of the mouse body 1. To be achieved by the mouse.

[0007]

[Action]

 That is, in the present invention, the ball 2 that rotates according to the amount of movement of the mouse body 1 is the magnetic ball 21, and the ball 2 is magnetically attracted to the operation surface 3 made of a steel plate or the like. A vertical surface (for example, the side wall of steel furniture) can be used as a space, and the work space can be effectively used.

[0008]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1A and 1B are sectional views showing an embodiment of the present invention. FIG. 1A shows a state of use on a horizontal operation surface 3 and FIG. 1B shows a state of use on a vertical operation surface 4.

In FIG. 1, reference numeral 1 denotes a mouse body, inside which a roller 12 for rotatably supporting a ball 2 and a substrate (not shown) for detecting a rotation amount through the roller 12 and converting it into a signal. Is built in, and an operation button 13 is provided on the upper part. A circular opening 14 is formed in the bottom surface portion 11 so that a part of the ball 2 projects downward.

The ball 2 is formed of a magnetic ball 21 having a diameter larger than that of the opening 14 of the mouse body 1. The magnetic material balls 21 can be formed by kneading powder of magnetic material into synthetic rubber or by coating the surface of the core material of magnetic material with synthetic rubber or the like. The magnetic balls 21 are partially projected from the bottom surface portion 11 and are rotatably abutted on the plurality of rollers 12 inside the mouse body 1.

The magnetic force of the magnetic balls 21 is set to such a degree that the adhesion is improved and the rotation of the magnetic balls 21 is not hindered on the operation surface 3 made of a steel plate or the like for adsorbing the magnetic balls 21. As shown in FIG. 1 (B), even on the vertical operation surface 4, magnetic force acts in the direction in which the magnetic material balls 21 come into close contact with the operation surface 4, so that the surfaces of the magnetic material balls 21 and the operation surface 4 are The magnetic balls 21 can rotate in response to the movement of the mouse body 1 without being separated from each other, and the coordinate input can be reliably performed.

[0012]

[Effect of device]

 As described above, in the mouse of the present invention, since the ball is brought into close contact with the operation surface by the magnetic force, the mouse can be operated by using the side surface of the steel desk, etc., and the horizontal operation surface can be used as the work space. Even if it is not possible to provide it, input can be done by operating the mouse and the work space can be used effectively.
