2. Description of the Related Art Conventionally, a directional key or the like used in a video game device or a portable electronic game device has a key top integrally formed, and a tip at the center of the bottom surface is spherical. A key top is operated in a seesaw manner with a fulcrum as a fulcrum.

[0003]

A directional key used in a conventional video game device or a portable electronic game device as described above has a key top integrally formed,
The key top is operated in a seesaw manner with the spherical part at the tip of the bottom center as a fulcrum.
It has a structure in which it is pressed in any direction of 60 °, and there is a drawback that the reliability of the operation is lacking.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems. A key top member is divided into a vertical key top member and a horizontal key top member. A concave portion is formed at a lower central position of the vertical key top member, a concave portion is formed at a central upper position of the horizontal key top member, and both concave portions are fitted with a clearance therebetween, and The directional keytop member and the lateral keytop member are arranged so as to be orthogonal to each other, and can be pressed in any one of two symmetrical directions from above the keytop exposed from the housing. A ring portion is integrally formed via a connecting portion extending in two directions of the vertical key top member, and the ring portion is located at a position orthogonal to the vertical key top member. It is characterized in that two protruding portions having a curved surface at the tip thereof are formed below the ring portion, and one protruding portion having a curved surface at a lower central portion opposed to the concave portion of the lateral key top member. It is a direction key characterized by being formed.

[0005]

The directional key of the present invention has two key tops exposed from the housing: a vertical key top and a horizontal key top.
Since it is divided, it is not a key that can be pressed in any direction of 360 ° as in the related art, and is a direction key that can be reliably operated in the direction desired by the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings. The drawings show an embodiment of the present invention, FIG. 1 is a perspective view of a key top member assembly, FIG. 2 is a perspective view of a vertical key top member,
3 is a perspective view of the horizontal key top member, FIG. 4 is a plan view of the vertical key top member, FIG. 5 is a front view of FIG. 4, FIG. 6 is a side view of FIG. 8 is a front view of FIG.

As shown in FIG. 1, the key top member is divided into a vertical key top member 1 and a horizontal key top member 2, and each of the key tops 11 and 21 is formed by a housing (not shown). It is arranged to be exposed. The vertical key top member 1 and the horizontal key top member 2 are combined so as to be orthogonal to each other, and the structure is clear from the perspective views of both key top members shown in FIGS. A concave portion 12 is formed at a position below the center of the vertical key top member 1 and the horizontal key top member 2 is formed.
A concave portion 22 is formed at a central upper position, and the concave portions are combined with each other with a clearance therebetween as shown in FIG. 1, and the vertical key top member and the horizontal key top member are arranged so as to be orthogonal to each other. ing.

The key tops 11 to 21 exposed from a housing (not shown) can be pressed from above the key tops 11 to 21 by using the projections 13 to 23 projecting downward in either of two symmetrical directions. It is configured.
That is, the ring portion 15 is formed integrally with the vertical key-top member 1 via the connecting portions 14 and 14 extending in two directions of the vertical key-top member 1, and is perpendicular to the vertical key-top member. Is formed, two projections 13, 13 each having a curved surface at the tip thereof are formed below the ring portion 15, so that the rubber contact support plate on which the projections 13, 13 are located is located.
(Not shown) and serves as a fulcrum when the key top 11 is pressed.

Further, since one projection 23 having a curved end is formed at the lower central portion of the lateral key top member 2 opposite to the recess 22, the rubber contact is located below the projection. The key top 21 is configured to be brought into contact with a part of a support plate (not shown) to serve as a fulcrum when the key top 21 is pressed.

Therefore, when one of the two symmetrical directions is pressed from above the key top 11 exposed from the housing, one of the contact pressing portions 16, 16 is arranged corresponding to the contact pressing portion, respectively. Rubber contacts (not shown)
, And this operation causes the circuit to be electrically short-circuited. Further, if any one of the two symmetrical directions is pressed from above the key top 21 exposed from the housing, one of the contact pressing portions 26, 26 is a rubber contact ( (Not shown), and this operation causes the circuit to be electrically short-circuited.

[0011]

Since the present invention has the structure described above, the operation of the directional key for designating the moving direction of the display character or the like in the video game device or the portable electronic game device is particularly difficult. There is an effect that the user can surely operate in the direction desired by the user.
