ABSTRACT:
A setting mechanism incorporated in a digital display device which includes a movable first digit carrier; a motor driving the first digit carrier in a normal digit-advancing operation; and a movable second digit carrier. The setting mechanism has a drive member continuously driven by the motor, a clutch connected between the drive member and the second digit carrier. The clutch, when in its engaged state, couples the drive member to the second digit carrier for imparting a setting motion to the latter; and a manually operable actuator connected to the clutch for operating the same.
