PURPOSE:To display the area number and the time of the area, by providing plural switches which have displayed area numbers corresponding to time difference divided areas of the world, and switch which has displayed a summer time mark, and depressing the switch of an optional area number. CONSTITUTION:When one part of plural switches 8 is turned on, an I/O port which has been controlled by a CPU 16 reads the state of the switch 8, and sends read data to the CPU 16. The CPU 16 discriminates the switch 8 in which a DST mark 7 has been described, or the switch 8 in which an area number 4 has been described, from the data which has been read, reads out data corresponding to each switch 8, from a ROM 19, and sends it to a display driver 18. The display driver 18 brings display data which has been sent, to power conversion, and applies it to a display part 6. The display part 6 displays the display data which has been sent. |
