Further, when the keystroke of the movable parts 2, 2, 2, 2 is released, the movable parts 2, 2, 2, 2 are moved upward by the elastic restoring force of the elastic legs 3, 3, 3, 3. However, the ON state of the contacts is released.

[0004]

[Problems to be solved by the device]

 In the conventional rubber contact 1, since the horizontal portion 4 is horizontally extended from the lower end portions of the elastic legs 3, 3, 3, 3 and the horizontal portion 4 is placed on the substrate. When the movable parts 2, 2, 2, 2 are depressed, the elastic leg parts 3, 3, 3, 3 are required to be more than necessary and sufficient strokes as the movable parts 2, 2, 2, 2 are lowered. It spreads in the horizontal direction, and eventually the elastic restoring force of the elastic legs 3, 3, 3, 3 was attenuated, and the long life of the rubber contact 1 could not be maintained.

[0007] Therefore, in striking the movable portions 2, 2, 2, 2 at the time of striking a key, a stroke is made constant, and a solution to prevent the lower end portions of the elastic legs 3, 3, 3, 3 from spreading is solved. However, the present invention aims to solve the above technical problems.

[0006]

[Means for Solving the Problems]

 This invention was proposed in order to achieve the above-mentioned object, and is a rubber contact provided in a controller or the like of a computer game machine or the like, and the rubber contact is a conductive rubber or the like at the lower end of the movable part. A movable contact is formed, and further elastic legs are installed obliquely downward from the outer periphery of the movable portion, and the movable contact is turned on to a fixed contact of a wiring pattern provided on the substrate by the vertical movement of the movable portion.・ In a rubber contact device configured to be turned off, ribs are provided so as to project from the lower end of the elastic leg portion at substantially equal intervals, and the lower end surface of the key top around which the movable portion is covered is provided on the rib. It is intended to provide a rubber contact characterized by being configured to be able to abut.

[0007]

[Action]

 When the movable portion is keyed, the lower end surface of the peripheral portion of the key top fitted to the movable portion contacts the upper surface of the rib. Therefore, since the stroke of the vertical movement of the movable portion is limited by the rib, it is possible to adjust the height of the rib so that a keystroke operation with an unnecessary keystroke cannot be performed.

[0008] Furthermore, when the movable part descends, the periphery of the lower end portion of the elastic leg portion tries to expand outward, but the expansion action is absorbed by the ribs, and the expansion is prevented. In combination with the above-mentioned function of the key top as a stopper, stable keystroke operation is always performed.

[0009]

The present invention will be described below in detail with reference to the attached drawings. For the convenience of explanation, the conventional publicly known technology will be described at the same time. FIG. 1 shows a controller 10, which is connected to a computer game machine (not shown) via a cable 11. The + character key 12 on the left side of the upper surface of the controller 10 is for moving the character on the screen vertically and horizontally. The central portion 13 is a select key, and 14 is a start / pause key. Each time it is pressed, the start and pause are switched. 15, 16, 17 and 18 on the right side and 19 and 20 on the left and right sides of the rear surface are trigger keys.

The seven select switches 21, 22, 23, 24, 25, 26, 27 disposed behind the select key 13 and the start / pause key 14 are start / pause key 14, trigger keys 15, 16, respectively. It corresponds to 17, 18, 19, 20. The select switch 21 only switches the operation mode of the start / pause key 14, and can select a normal start / pause key and a slow mode in which the start and pause are automatically repeated after the start to obtain a so-called slow motion effect. The select switch 22 corresponds to the trigger key 19, 23 corresponds to 20, 24 corresponds to 15, 25 corresponds to 16, 26 corresponds to 17, and 27 corresponds to 18, respectively.

FIG. 2 is a plan view of the rubber contacts 29 of the trigger keys 15, 16, 17, 18 provided in the controller 10. In addition, in this embodiment, the rubber key contact of the trigger key is described, but the present invention should not be limited to this. FIG. 3 is a sectional view taken along the line AA of FIG. 2, wherein the rubber contact 29 is made of an elastic rubber material as described in the conventional example, and the central portions of the trigger keys 15, 16, 17, 18 are respectively formed. Movable parts 30, 30, 30, 30 are provided in each of the movable parts 30, 30, 30, 30, and elastic leg parts 31, 31, 31, 31 are obliquely provided obliquely downward from the respective outer peripheral intermediate parts. The lower end surfaces 31a, 31a, 31a, 31a of the elastic legs 31, 31, 31, 31 are placed on the upper surface of the substrate (not shown). In addition, movable contacts 32, 32, 32, 32 are provided at the lower ends of the movable parts 30, 30, 30, 30 respectively with conductive rubber, and the movable contacts 32, 32, 32, 32, The lower end surface of 32 is located above the lower end surfaces 31a, 31a, 31a, 31a of the elastic leg portions 31, 31, 31, 31 in a state where the movable portions 30, 30, 30, 30 are not pressed (keystroke operation). The movable portion 30, 30, 30, 30 is positioned by a keystroke operation and moves down against the elastic biasing force of the elastic legs 31, 31, 31, 31 to electrically connect the fixed contacts of the wiring pattern provided on the substrate. It is designed to be physically connected. Then, by releasing the pressing operation, the movable portions 30, 30, 30, 30 are moved upward by the elastic restoring force of the elastic leg portions 31, 31, 31, 31, and the electric coupling is released. It

The rubber contact 29 is disposed at the trigger keys 15, 16, 17, 18 shown in FIG. 1, is covered with the cover 33, and each movable portion of the rubber contact 29 is covered. 30, 30, 30, 30 are made to project from the openings 33a, 33a, 33a, 33a provided in the cover 33 to the upper surface, respectively, and further, the movable portions 30, 30, 30, 30 are respectively provided with key tops 34, 34, 34, 34 are fitted.

Further, the rubber contact 29 is horizontally extended from the lower end portions 31b, 31b, 31b, 31b of the elastic leg portions 31, 31, 31, 31 to form a horizontal portion 31c. Then, ribs 35, 35, 35, 35 are projectingly provided on the horizontal portion 31c at equal intervals from the lower end portions 31b, 31b, 31b, 31b of the elastic leg portions 31, 31, 31, 31. .. The ribs 35, 35, 35, 35 may be intermittently formed by providing cut portions 35a, 35a, 35a, 35a in places.

Further, as shown in FIG. 4, the lower end surface 34 a of the peripheral portion of the key top 34 fitted to the movable portion 30 is located on the upper surface of the rib 35, and when the key top 34 is pressed, The lower end surface 34a of the peripheral portion of the key top 34 comes into contact with the rib 35, and the keystroke stroke is restricted. Therefore, the height of the rib 35 should be necessary and sufficient for the keystroke stroke, and at the same time, it should be possible to limit the unnecessary stroke. Further, the ribs 35 are configured so that the lower end portion 31b of the elastic leg portion 31 at the time of keystroke can absorb the action of expanding to the periphery.

It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

[0016]

[Effect of the device]

 In this invention, as described in detail in the above-mentioned embodiment, ribs are projected from the lower end of the elastic leg of the rubber contact at equal intervals, so that the lower end of the periphery of the key top is It abuts against the rib, and thus the lowering operation of the movable part is stopped by the rib. Therefore, by adjusting the height of the ribs to be constant, the keystroke stroke becomes constant, and a stable keystroke operation is always performed.

Further, at the time of tapping, the lower end portion of the elastic leg portion tends to spread to the periphery as the movable portion descends, and this spreading action is also absorbed by the ribs, In combination with stable keystrokes, the elastic restoring force of the rubber contact is prevented as much as possible, and the long life of the rubber contact can be maintained. It is a device.
