PURPOSE:To make it possible to set a correction speed corresponding to the correction range of the time mode of an electronic watch, by generating pulses whose number corresponds to a mode of the rotation speed of a rotary switch, time, date, etc. CONSTITUTION:Hour counter 15, date-month counter 16 and week counter 17 selected by terminal outputs M, D and W of time-mode selector circuit 26 are supplied with correction pulse (u) from divider 13 via gate circuits 45, 31, 35, and 39. As for the number of supplied pulses, output 18a of counter 18 stays at ''1'', when switches 60 and 61 turned ON-OFF through the rotation of the correction shaft are turned at a low speed, to supply one pulse on each switching of switches, but when switches are turned ON-OFF at a high speed, the output of counter 18 is held at ''0'' to supply counters 15 to 17 with pulses as many as counter 19 counts up pulses to fixed numbers of respective modes. |
