摘要

A control-key device is provided for use as a controller for a video game including a direction specifying key mounted on a housing which an operator manipulates to control the play of a video game, where the surface of said direction specifying key comprises a combination of concave portions to facilitate use of the direction specifying key. The unit preferably comprises a push button and a housing including a hole through which the push button protrudes. The housing extends along a plane wherein said plane intersects a plane perpendicular to an axis of said push button at a predetermined angle, and said plane of said housing also extending parallel to a plane defined by the surface of said push button. In a preferred embodiment, the push button is mounted in a manner such that the push button has a rotation axis and a plurality of operating surfaces, where each of said plurality of operating surfaces includes a projection that forms a surface perpendicular to the rotational direction defined by said rotation axis.
