Abstract

PURPOSE: To improve the utilization efficiency of a printer unit with a simple constitution by providing a multiplexer which selects input signals from data processors and transmits a fixed signal to the printer.
CONSTITUTION: Printer unit 3, connected to word processor bodies 1 and 2 as data processors via printer share mechanism 4, is shared between processors 1 and 2. This share mechanism 4 is provided with data multiplexer 41 provided with input terminals A and B, and data multiplexer 42 provided with output terminal A and B. Further, FF circuits 43 and 44 are provided which transfer signals berween signal lines 63W65, and 73W75 connected to processors 1 and 2, and AND gates 45 and 46 which are connected to set terminals of circuits 43 and 44 and receive outputs Q of signal lines 64 and 74, and circuits 43 and 44 are also provided. Then, circuits 43 and 44 select an input signal to transmit a signal from multiplexer 41 to printer unit 3, and an answer signal from unit 3 is transferred to processors 1 and 2 via multiplexer 42.
