PURPOSE:To monitor various timepeice data for imprinting through only one display by selectively displaying desired data among various time data for imprinting counted by a counting circuit. CONSTITUTION:When a selection switch 70 is operated once, an FF71 is set to apply a high level clock from a clock generator 74 to AND gates 81, 82, 85, and 86, and the high level Q output of an FF75 is applied to the AND gates 81-84 to pass digit signals for year digits of tens and units from a data decoding circuit 80 through OR circuits 91 and 95 and a driver 92 by AND gates 81 and 82, controlling year digits of tens and units on a monitor display 90. Consequently, segment driving signals for year digits of tens and units from the circuit 80 are applied through a driver 85 to the display 90, where year data in time data for imprinting is displayed. Similarly, month data, day data, etc., are monitored on the same monitor display selectively without using several displays. |
