摘要： An electronic timepiece is provided with a correction signal generating system for producing correction pulses to modify current time or other data. The system includes a rotary switch, coupled to a timepiece crown to be rotated thereby and having a plurality of fixed and movable contacts, with the number of movable contacts being less than the number of fixed contacts, and circuit means for producing a train of correction pulses from either of two output terminals in accordance with the direction of rotation of the timepiece crown. Correction pulses from one of these output terminals serves to increment the quantity being corrected, while correction pulses from the other output terminal serve to decrement that quantity. Gearing may be provided between the crown and the switch rotor, to increase the maximum rate of generation of correction pulses.

摘要： A heavy-load driving device for a electronic watch is provided that assures reliable timekeeping operation and enables proper drive in accordance with the power supply voltage level. When drive command circuit generates an alarm-coincidence signal Sa, this signal Sa causes a preparatory judging circuit 10 to operate, so as to make a judgment, in accordance with the reduced power supply voltage level under a given load condition, as to whether or not to allow drive of a beeper device 31, a drive-enabling signal Svm being output if the judgment is to allow drive. By doing this, a heavy-load voltage detection circuit 21 starts to output a drive-time judgment signal Pvh which indicates the power supply voltage level judgment results. By means of the Svm signal, the a drive-signal control circuit 23 begins to operate, and at a drive condition selection circuit 25, in accordance with the signal Pvh, successive selection is made of a drive signal to be supplied to the beeper device 31 from the plurality of drive signals B75, B50, and B25 which are generated by the a drive-signal generating circuit 16, the selected drive signal driving the beeper device 31.
