PURPOSE:To enable to avoid the delay in the initial discharge, by compulsively illuminating a part or all of the display for a given time at the application of the power supply. CONSTITUTION:The delay circuit 17 delivers signal with a suitable time delay after compulsive application of power supply, and the fixed memory 12 instructs the illumination of a part or all of the display units 1 in the delay time. Further, the AND group 16 is provided to lock the input data from the key 7 in this time to illuminate the display units 1 with the signal from the memory 12. Further, when all the illuminating parts of the dispaly units 1 are illuminated on the display data fixed memory 18, the signal of high potential is delivered to the AND circuit group 19. Thus, the delay in initial discharge of the display units can be avoided. |
