CONSTITUTION:When a reset switch S2 isopened, the counting action of clock pulses CP1 through a dividing counter 4a is keptdiscontinued. Thus the 1-second pulse is not produced, and at the same time a 1-secondcounter 4b is reset. The terminal output C3 of a 10-second counter 4c is set at binarydigit 0 and binary digit 1 when the reset operating time is 00-39 seconds and 40-59seconds respectively. Then the switch S2 is closed again and the second display is set at00 second. Thus the minute display is kept as it is or advanced by a minute in accordancewith the second display in the reset mode.
