Abstract

PURPOSE:To obtain an input device provided with few keys, by comparing an output of a device for counting the length of a contact time of a specific key, with each set value of a device for setting a time, and outputting a coincidence signal when both of them are made coincide. CONSTITUTION:When a pulse train 15 is outputted to an output line 6 corresponding to a key switch, the number of pulses which have been counted 9 is compared with contents of registers 7A-7C, and when it coincides with one of the registers, collation coinciding circuits 8A-8C output a coincidence pulse, and it is inputted to an encoder 5, and also is inputted to a latching circuit 10. As a result, plural different signals can be generated by one key switch, and its selection can be executed depending on length of a depressed time. In order to discriminate a timing for letting a finger loose, a character and a symbol coinciding with contents of the register are displayed in order in an indicator which is not shown in the figure. In this way, it is possible to form a small- sized device which is capable of operating a lot of inputs by a few keys.
