Abstract
The present invention relates to a multi-directional input unit. A thin plate-type operating member having an elastic force is fixed to any one of first and second keytops, and the first and second keytops are elastically urged to a predetermined height whereby a reliable click is generated. A portion of an outer peripheral portion of an operating member is mounted on a fixing plate, a first operating portion or a second operating portion is fixed to either the first or second keytops, the first and second keytops are elastically urged to a predetermined height from the fixing plate, and when either of the first and second keytop are pressed down, either of the dome-shaped first and second keytops are inverted, whereby a switch portion is operated.
