摘要： A dynamically driven printer is provided for printing the output of a device having a memory register, the printer including print means operable directly from said memory register without an intervening temporary memory register in a manner corresponding to the operation of a segmented digital electronic display. The operating periods of the print means and memory register need not be synchronized. The print means may include a plurality of segment printing devices at each digit position, corresponding segment printing devices at each digit position being coupled together for simultaneous receipt of driving signals generated in response to the output of the main memory register. Each of the digit positions is sequentially actuated to effect printing.

摘要： A driving device for an electronic timepiece including a multipole stepping motor driven by an alternative pulse generator operating under the control of a time standard oscillator. The timepiece includes a time indicating gear train including an indexing mechanism having a pawl and a ratchet wheel attached to the second wheel of said train to insure the incremental step action of said stepping motor.
