PURPOSE:To enable Sunday to be arbitrarily selected and displayed through operation of an external operation button by providing the displays of Sunday on both left and right sides of day symbol marks. CONSTITUTION:Respective day displays are displayed by symbol marks 12 and display bodies 11 provided thereunder. The symbol marks of Sunday are provided 12a and 12h on both left and right sides. When a switch 21 is turned ON in the curreent state where the symbol mark 12a has been selected and the display body 11a lights to indicate that it is Sunday, then the signal of 1 is inputted to a flip-flop 22 and the output Q thereof changes from 1 to 0. And the outputs of gates 26i, 26a become pulses of 32 Hz and of the inphase as that of a common electrode 30 and therefore the symbol mark 12a and display body 11a go off. The outputs of gates 26j, 26h become of antiphase from that of the common electrode 30 and the symbol mark 12h and day display body 11h go on. |
