PURPOSE:To miniaturize a receiver and to improve the operability in confirming display data at a dark place by using a reset switch in common with a switch for a liquid crystal display of a display device to eliminate the need for the switch of the LCD and allowing a decoder to turn on/off the LCD together with the control of the display of the display device. CONSTITUTION:A conventional lighting lamp switch is abolished and a transistor (TR) 14 controlled by the decoder 4' is provided instead to drive a lighting lamp 9. When the time for the depression of a reset switch 12' is within 2sec, the display device 8 is started and the display is performed and when the time is >=2sec, the display device 8 is started, the TR14 is brought into the nonconductive state from the conductive state, the display is performed and the lighting lamp 9 is turned on. Further, the decoder 4' is provided with a 8-sec timer, and if the state that no reset switch 12' is depressed continues for 8sec the TR14 of nonconductive state is brought into the conductive state, the start of the display device 8' is stopped, the lighting lamp 9 is extinguished and the display of the display device 8' is stopped. |
