い操作性の面で難があった。The control key device described above has a structure in which the key portion always slides on the outer surface of the dome portion and the contact pressing portion always slides on the inner surface of the dome portion. Therefore, during operation, the pad always slides on the upper and lower surfaces of the dome portion. In order to push the pad to incline the contact pressing portion to press the contact, the pad has to slide and incline the dome portion, and some stroke is required until the contact presses. For this reason, the operation takes a long time, which is difficult in terms of operability.

装置を提供することにある。Further, since the pad is constructed so as to always slide on the dome, a clearance is required around the pad so that it can move freely. This gap is related to the size of the spherical surface of the dome. The radius of curvature of the spherical surface of the dome requires a stroke of the conductive portion of the conductive elastic member of 1 mm or more, and the distance between the conductive portions is set to some extent in order to press the conductive portion without malfunction due to the contact pressing portion being inclined. It is decided based on what is necessary. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a control key device which is less responsive during operation and has less space around the key portion.

d is lowered downward against the elasticity of the conductive elastic portion 5, and the sliding contact portion 2g of the key top comes into contact with the surface of the dome portion 3b of the front case. In this state, the foot portion 4a of the contact pressing portion 4
4d uniformly pushes down the conductive portions 5a to 5d of the conductive elastic portion 5, but none of the conductive portions 5a to 5d come into contact with the electrical contacts 6a to 6d of the wiring board 6. This is because the key top is lowered by the gap s between the sliding contact portion 2g of the key top and the dome portion 3b of the front case. Even if the conductive portions 5a to 5d are lowered by the gap s, the gap g between the conductive portions is larger.
5d does not contact the electrical contact portions 6a to 6d of the wiring board 6.

Due to this pressing force, the sliding contact portion 2g of the key top 2 slides on the surface of the dome portion 3b and tilts, the contact pressing portion 4 fixed to the key top 2 tilts, and the foot portion 4c of the contact pressing portion 4 conducts. The conductive portion 5c of the elastic portion 5 is pressed. Here, since the center of curvature P of the dome 3b is at the center of the height position of the conductive portion, the foot portion 4c of the contact pressing portion 4 pushes the conductive portion 5c substantially horizontally. As a result, the conductive elastic portion 5 is elastically deformed,
The electrical contact portion 6c is conducted by the conductive portion 5c.

The distance of c is gs. In this state, the protrusion 2c of the key top is pushed down, and the sliding contact portion 2g slides and tilts the key top on the outer surface of the dome portion 3b. The portion 6c becomes conductive. At this time, the foot portion 4d on the opposite side tilts upward between the wall surfaces 3c on both sides thereof.

As a result, the contact pressing portion 4 is lifted upward, and the key top 2 is lifted until the convex spherical surface portion 4e of the contact pressing portion comes into contact with the inner surface of the dome portion 3b of the front case.

るのである。The wiring board 6 has two pairs of electric contact portions 6a, 6b and 6c, 6d symmetrically arranged on the circumference E of FIG. Each foot portion of the contact point pressing portion 4 is formed by annularly notching the wall surface 3 below the outer periphery of the dome portion 3b of the front case 3.
It is designed to be exposed outside from between c and to be placed on each conductive portion of the conductive elastic portion 5, and when the protrusion of the key top 2 is pushed down, the key top 2 slides at the sliding contact portion 2g and the outer surface of the dome 3b. Since the contact pressing portion 4 is slidably held on the wall surface 3c, the contact pressing portion 4 tilts and presses the conductive portion by the foot portion, and the electric contact portion of the wiring board 6 is conducted. At this time, the foot portion on the opposite side tilts upward between the wall surfaces 3c on both sides.

The elastic deformation of the conductive part returns, but the wall surface 3c of the front case
While maintaining its center position, the upper surface of the contact pressing portion 4 contacts the lower end of the cylinder 2e of the front case 3. The key top 2 sandwiches the foot portion of the contact pressing portion 4 between the respective wall surfaces 3c. Since the contact pressing portion 4 is tiltable at that position, it is always neutral at the center position and returns to the initial state. The sliding contact portion 2g of the top 2 is opened and held by a distance s from the dome portion 3b.

When the key top comes into contact with the surface of the key, it enters the standby state, and if you apply force in the direction you want to press from it, you can tilt the key top with the minimum movement of the key top, improving the responsiveness of the key and further The gap with the surrounding front case can be made small so that dust does not enter this gap and your hands are not caught.

き、非常に勝れたコントロールキー装置となっている。Further, since the contact pressing portion is tilted to bring the conductive portion of the conductive elastic portion into contact with the wiring board, each electric contact portion intended by the operator can be secured without making a pivotal fulcrum of the contact pressing portion. Can be conducted to. In addition, even if a large impact is applied to the operation surface of the keytop from above, it is possible to prevent the impact from being transmitted to the wiring board and prevent damage to the wiring on the wiring board or the wiring joint. , The control key device has been extremely won.
