Abstract

(57) [Summary] [Purpose] To prevent the mouse cursor from moving when the user releases the mouse body while using the mouse. [Structure] When the mouse body is pressed, the ball becomes rotatable. When the mouse body is moved, the ball rotates and the mouse cursor on the display device moves.
When the mouse body is not pressed, the ball does not rotate and the mouse cursor does not move. Therefore, when the hand is released from the mouse body, the mouse cursor is prevented from moving due to displacement or the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mouse used as a coordinate input device for indicating a point on a display device such as a computer, and more particularly to a mouse in which a ball exposed on the lower surface does not rotate except when in use.

[0002]

[Prior Art]

 As a coordinate input device for moving the cursor on the display device connected to a computer etc., the operator uses the rotation of the ball to move in any direction on the mouse mat or desk and inputs the amount of movement. The mouse is used.

In a conventional mouse, when the operator releases his / her hand from the mouse while performing processing such as drawing, the ball rotates due to some shock or light force. , The mouse may move and the mouse cursor on the display may be displaced from the currently drawn target.

[0004]

[Problems to be solved by the device]

 As described above, when the mouse moves and the mouse cursor on the display device deviates from the currently drawn coordinates, the mouse cursor has to be moved to the currently drawn coordinates, especially when drawing in dots. In addition, in the worst case, there was a problem of forgetting the coordinates currently being drawn.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mouse in which the movement of the mouse cursor is prevented when the mouse is released from the main body during use.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a ball rotatable in an arbitrary direction, a main body for storing a part of the ball exposed on the bottom surface side, and a projection provided on the bottom surface side of the main body. An elastic member that allows the ball to rotate when the main body is pressed is provided.

[0007]

[Action]

 Since the present invention is configured as described above, when the mouse body is moved while being pressed, the ball rotates to move the mouse cursor on the display device, and the mouse body is moved without being pressed. Sometimes the ball doesn't rotate and the mouse cursor doesn't move.

[0008]

【Example】

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

1 and 2 are cross-sectional views of a mouse according to an embodiment of the present invention, FIG. 1 is a non-operating state, and FIG. 2 is an operating state.

In the above figure, reference numeral 1 denotes a mouse, which is a mouse body 3 having an operation button 2 on its upper surface, and a part of the mouse body 3 which is exposed from the bottom surface thereof and is rotatably housed and held. Ball 4 and the springs that are higher than the exposed part of the ball 4 exposed on the bottom of the mouse body 3 and that are fixed and held, for example, protruding from the four corners of the mouse body 3 and fixed. It is composed of elastic members 5 and 5 that can be expanded and contracted.

When the mouse 1 is not manually pressed by the operator, as shown in FIG. 1, the ball 4 does not come into contact with the mouse mat 7 placed on the desk 6 and becomes inoperative. Further, when the mouse 1 is manually pressed by the operator, as shown in FIG. 2, the elastic members 5, 5 contract and the ball 4 comes into contact with the mouse mat 7, and the ball 4 becomes rotatable. When the mouse 1 is moved while the ball 4 and the mouse mat 7 are in contact with each other, the ball 4 rotates, and the mouse cursor on the display device (not shown) moves as the ball 4 rotates.

Next, the operation of the embodiment of the present invention having the above structure will be described.

First, when the mouse 1 is in a non-operating state, the operator does not touch the mouse 1 or the operator does not press the mouse 1 downward, so that the elastic members 5 and 5 maintain the extended state. Therefore, the ball 4 does not come into contact with the mouse mat 7. Therefore, even if the operator releases the mouse 1 or moves the mouse 1 in this state, the ball 4 does not rotate, so that the movement of the mouse cursor or the like is prevented.

On the other hand, when the user wants to move the mouse cursor with the mouse 1, the operator pushes the mouse 1 downward to contract the elastic members 5 and 5 to bring the ball 4 into contact with the mouse mat 7 and rotate the ball 4. Enable state. When the mouse 1 is moved in this state, the ball 4 rotates while contacting with the mouse mat 7, and the mouse cursor on the screen moves as the ball 4 rotates. When the operator releases the mouse 1 from the operating state of the mouse 1, the mouse 1 becomes the non-operating state, the ball 4 becomes unrotatable, and the displacement of the mouse cursor is prevented.

The present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0016]

[Effect of the device]

 As described above in detail, according to the mouse of the present invention, the ball can be rotated only when the body of the mouse is pressed, and the ball does not rotate when the mouse is inactive. It is possible to prevent the mouse cursor from being displaced when the cursor is on.
