Abstract

PURPOSE:To efficiently operate a key by a simple structure, by switching the surface and the reverse side, and the upper and lower stages of one key mat card, executing the combination of at least 4 ways, and inputting a lot of functions by a key. CONSTITUTION:A key mat card 1 can be inverted by detaching it entirely from the body, and on the card 1, for instance, a push-button part 2 having 8 lines and 8 rows, and a key display part 3 are provided. Said push-button part 2 is fitted into a switch of a key matrix provided on the lower surface, the circuit is closed by depressing the push-button, and the switch is closed by depressing the push-button irrespective of the surface or the reverse side of the card 1. Also, the display part 3 is displayed in 2 upper and lower stages, and even if the same push-button part 2 is depressed from both the surface and the reverse side, a signal of only one of an upper stage part 6 or a lower stage part 7 is outputted by switching a switch 5. Also, on the upper corner part of the card 1, a surface and reverse side discriminating window 8 is formed, and when the window 8 is made to face surface and reverse side discriminators 9, 10 consisting of a switch, etc., a discriminating signal is generated.
