ABSTRACT:
A multidirection input apparatus including a housing, a driving member movably positioned within the housing, and an operation member fixedly attached to the driving member and extending from the housing for manual manipulation. The driving body is supported by an elastic member over an input switch. The elastic member includes six protrusions (two rotation protrusions and four tilt protrusions), each protrusion having a movable contact formed on a lower surface of the elastic member, and each movable contact is positioned over an associated fixed contact located on a lower substrate of the housing. Manual rotation of the operation member causes rotation of the driving member which, in turn, presses against one of the two rotation protrusions, thereby causing the movable contact associated with the rotation protrusion to contact its associated fixed contact on the lower substrate. Manual tilting of the operation member causes tilting of the driving member which, in turn, presses against one or more of the tilt protrusions, thereby causing the movable contacts associated with the tilt protrusions to contact their associated fixed contact on the lower substrate. Downward pressure on the operation member causes the driving member to actuate the input switch.
