Abstract:
1. A wrist-portable apparatus comprising: a case; a display member rotatably mounted in the case for displaying information; an operational shaft mounted to undergo rotational and sliding movements relative to the case so that the operational shaft may be axially displaced between a pushed-in position, in which the operational shaft is pushed into the case, and a drawn-out position, in which the operational shaft is drawn out from the case; a clutch assembly for transmitting rotational movement of the operational shaft to the display member to rotate the display member when the operational shaft is displaced to the drawn-out position and for releasing the transmission of the rotational movement of the operational shaft to the display member when the operational shaft is displaced to the pushed-in position, the clutch assembly comprising a gear integral with the operational shaft and a rack integral with the display member for meshing engagement with the gear to transmit rotational movement of the operational shaft to the display member when the operational shaft is displaced to the drawn-out position but not when the operational shaft is displaced to the pushed-in position; and a manual control stem integrally connected to an end of the operational shaft and disposed on a side surface portion of the case for controlling rotation of the operational shaft and displacement of the operational shaft to the pushed-in and drawn-out positions.
