PURPOSE:To prevent erroneous operation and to output a plurality of different operation signals by arranging close to one another a plurality of touch switch elements and outputting a plurality of different operation signals in accordance with operation direction of a touch switch element in a specified time. CONSTITUTION:Time setting mode selection touch switches 28a-28c, and 32a- 32c are formed on the cover glass 26 provided on a liquid crystal panel 24. A time setting mode detection circuit 34 performs changing-over to either of the yir time setting mode or the ordinary time display mode according to the direction of touching of one of touch switch elements 28a-28c in a specified time. Further-more, detection circuits 72 and 74 perform setting of gain and delay according to the direction of operation in a specified hour setting touch switches 30a-30c and minute setting touch switches 32a-32c. |
