PROBLEM TO BE SOLVED: To enable a player to obtain a strong click feel and to prevent the exertion of undue force on an internally located mechanism switch section by setting a shaft and a cruciform member so as to push a mechanical switch when the shaft is tilted around the root part of a shaft as a fulcrum. SOLUTION: When the game player activates a key top part 42a1 in an arrow direction, a transmission section 42a2 oscillates around a contact portion of a fulcrum section 42a23 and one of the front ends of the cruciform section 42a22 pushes the movable point of a mechanical switching section 42a3 accompanying this oscillation. The collision of the front end of the cruciform section 42a22 of this time and the movable point of the mechanical switching section 42a3 gives rise to the strong click feel. Additionally, while the movable point of the mechanical switching section 42a3 among the fulcrum portions 42a23 of the transmission section 42a2 is pushed, the rear surface comes into contact with the inner base surface 42a5 of a cover section 42a4. As a result, the movement of a rod-like section 42a21 is regulated and, therefore, the exertion of more than needed large force at the movable point of the mechanical switching section 42a3 does not occur. |
