PURPOSE:To correct within a short period without increasing the number of digits to be selected, by providing a quick feed pulse generating circuit which output a plurality of pulse signals by one operation of the operating member. CONSTITUTION:An operating member 14 is designed to select the digit to be corrected. When the minute digit is selected, the one input of AND gate 20 becomes H. similarly, when the hour digit is selected and the date digit is selected, the one input of AND gate 22 and 24 respectively becomes H. At the same time, a pulse signal for quick feeding is applied to the other input of AND gate 20, 22, 24. Thie quick feeding pulse operates an operating member 32, which causes quick feed pulse generator circuits 36, 38 to output quick feeding pulses by the predetermined number of pieces at every one operation, thereby performing quick feeding correction. A scale-of-N counter 40, and flipflops 42, 44 detect the time intervals of operation of the operating member 32, and the number of quick feeding pulses is determined on the basis of such detected signal. |
