Abstract

PURPOSE:To invert digital display and enable visual recognition of time information even when viewed through a mirror by display-controlling the time information having been displayed on a display device consisting of plural digits with a changeover means. CONSTITUTION:Reference signal from an oscillator 1 is sent to the time counting means of a frequency dividing circuit 2, etc. and the time information is displayed in the display bodies 10a thru 10f of 6 digits of a display part 10 through a changeoever control circuit 8 and driver 9. On the other hand, a digit selecting circuit 11 constituted by hexad counters is provided to send the signal to a driver 14 via changeover control circuit 13. By the count value of the selecting circuit 11, the signal is supplied to the common electrode (h) of one display body out of the display bodies 10a thru 10f. Changeover operation of the changeover control circuits 8 and 13 is accomplished by a changeover switch 15 and as the changeover switch 15 is turned on, the signals being inputted to the segments (b) and (c) and the signals being inputted to the segmetns (e) and (f) are mutually changed over and displaying of the display part 10 is inverted.
