Abstract

PURPOSE:To reduce the power consumption as well as to eliminate the factor of malfunction, by providing a switch that excludes the undesired circuit when a removable keyboard part is loaded to the device main body. CONSTITUTION:The keyboard part 2 of the device main body 1 of a typewriter or the like can be removed freely. In case the part 2 is put apart from the main body 1, the input signal supplied from the input key 2a is put into the input key circuit within the main body 1 via the transmitting antenna 4 and the receiving antenna 5 each. When the part 2 is oaded into the main body 1, the power source of the main body 1 can be used for the part 2. Furthermore the power can be supplied to the key input circuit with no intervention of the transmitter/receiver circuit. Thus the switch contacts A and B or E and F are provided for connection or elimination of these power source, circuits and others. Then each switch is opened and closed by the projections 7 and 8 provided at the main body 1.
