[Problems to be solved by the device]

 However, it has been clarified that in the conventional mouse having a relatively large area push button as described above, the operability and appearance of the push button are improved, but the following problems are likely to occur.

That is, for example, when the push position of the push button 12 is near a corner portion deviated from the central portion of the push button 12 as shown by a white arrow in FIG. 5, the push button is largely inclined. However, the descending distance of the plunger portion 7 and the pressing amount of the switch 6 do not become so large, and the switch 6 may not operate even if the push button 12 is pressed (clicked). There was a possibility that it might occur to some extent.

That is, in the mouse 1 including the push button 12 having a relatively large area as described above, a dead point is likely to occur on the push button 12.

In view of the above point, the present invention has an object to provide a coordinate information input device that does not cause a dead point even when the operability of the push button is improved.

[0009]

[Means for Solving the Problems]

[0010]

[Action]

 In the coordinate information input device according to the present invention configured as described above, even when the push button is pressed in the vicinity of the corner portion deviated from the central portion thereof, the plurality of hooking protrusions are hooked. Since the push button is prevented from tilting or twisting beyond a certain level, there is a switch between the push button pressing position and the locking projection locking position. Therefore, the pressing amount of the switch is sufficiently secured.

Therefore, the switch can be operated reliably regardless of which part of the push button is pressed, and a dead point does not occur in the push button.

[0012]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 mainly show around a switch of a one-button type mouse which is a coordinate information input device according to the present invention. In these figures, parts corresponding to respective parts of the conventional mouse described above are shown. Are given the same reference numerals to omit or simplify their description, and in the following, the difference between the mouse of the present embodiment and the conventional one will be mainly described.

Like the conventional mouse 10, the mouse 10 of this embodiment basically accommodates a ball 3 for inputting coordinate information and the ball 3 with a part of its outer surface exposed. The case 14, the cover 15 that covers the case 14, and the inner cover portion 16 that is formed on one end of the cover 15 are arranged so as to cover the upper surface. A spring portion 18 is provided on one end side. A push button 12 provided and a switch 6 mounted on the wiring board 5 arranged in the case 14 and operated by the push button 12 are provided. The coordinate information signal is transmitted based on the above, and a signal indicating the operating state of the switch 6 is transmitted.

When the switch 6 and its surroundings are viewed in more detail, a plunger portion 25 having a T-shaped cross section for pressing the switch 6 is provided on the lower surface side of the push button 12 in the approximate center in the left-right direction. Is provided so as to project downward, and a pair of locking projections 23 is provided so as to project downward from the plunger portion 25 on the left and right sides so as to sandwich it. The latching projection 23 has a lateral U-shape with an opening 24, and a reinforcing rib 26 is provided in the vertical direction on the front surface thereof.

On the other hand, the inner cover portion 16 is formed with a through hole 35 through which the plunger portion 25 is inserted, so that the switch 6 attached to the wiring board 5 can be pressed, and a pair of left and right latches are provided. Openings 33, 33 for inserting the projecting piece 23 are formed, and when an external force is applied to the push button 12 to incline or twist the push button 12, the push button 12 is protected from the external force by a certain amount or more. Twist prevention hooks 34 are provided in the openings 33, 33 with which the pair of hooking projections 23 are locked so as to prevent tilting or twisting.

That is, around the twist prevention hook 34, there is formed a convex opening 33 through which the above-mentioned hooking projection 23 is inserted, and as shown in FIG. 3, the twist prevention hook 34 is locked. When the push button 12 is inserted into the opening 24 of the projecting piece 23 and the push button 12 is tilted or twisted to a certain degree or more, the lower side of the latching projecting piece 23 is locked.

The cover 15 is formed with an insertion opening 31 for inserting the spring portion 18 of the push button 12, and the spring portion 18 is fixed on the lower surface of the cover 15 as shown in FIG. The front side of the push button 12 is fixed to the convex piece 17 so that the push button 12 can be rocked vertically.

Further, at the front ends of the cover 15 and the case 14, a hook hook portion 42 and a hook gate portion 44 for assembling the cover 15 to the case are provided, and a cord outlet 45 is also provided.

In the mouse 10 of the present embodiment configured as described above, even when the push button 12 is pressed in the vicinity of the corner portion deviated from the central portion thereof, the pair of locking projections 23 are provided. Since the hook is locked to the twist prevention hook 34, more than a certain inclination or twist of the push button 12 is prevented, and at this time, the pressing position of the push button 12 and the locking position of the locking projection 23 are held. Since the switch 6 exists between and, the pressing amount of the switch 6 is sufficiently secured.

Therefore, the switch 6 can be reliably operated regardless of where the push button 12 is pressed, and a dead point does not occur in the push button 12.

In addition, in the above-mentioned example, a pair of the latching protrusion and the anti-twist hook are provided on the left and right, but the number and position of them are not limited to those described above, and they are not limited to the above. It can be appropriately set according to the area of the push button and the like.
