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.
Claims19
A setting mechanism incorporated in a digital display device which includes a movable first digit carrying means;
- a motor driving the first digit carrying means in a normal digit-advancing operation;
- and a movable second digit carrying means;
- wherein the improvement comprises:
- a. a drive member continuously driven by said motor;
- b. clutch means connected between said drive member and said second digit carrying means, said clutch means having an engaged and a disengaged state;
- said clutch means, when in its said engaged state, coupling said drive member to said second digit carrying means for imparting a setting motion to the latter;
- and
- c. manually operable actuating means connected to said clutch means for placing said clutch means from one of its states into the other.
A setting mechanism incorporated in a digital display device which includes a movable digit roller;
- stepping elements affixed to the digit roller;
- a stepping gear;
- a motor connected to the stepping gear for continuously rotating the latter;
- a stepping member secured to and carried in an orbital motion by said stepping gear;
- the stepping member, upon rotation of the stepping gear, periodically engaging the stepping elements for effecting a step-by-step advance of the digit roller;
- wherein the improvement comprises in combination
- a. a clutch pinion in continuous engagement with said stepping gear;
- said clutch pinion having a first position in which it is disengaged from said digit roller;
- said clutch pinion having a second position in which it is in engagement with said digit roller for coupling said digit roller to said stepping gear through said clutch pinion for effecting a setting motion of said digit roller by said motor;
- b. a manually operable actuating means being coupled to said clutch pinion for moving said clutch pinion from one of its positions into the other;
- and
- c. means rendering said stepping member ineffective during the setting motion of said digit roller.
