徴とするハードコピー機用コネクタ。[Scope of Claim for Utility Model Registration] A hard copy machine connector interposed between a plurality of display devices and one hard copy machine, through which data is sent to the same number of unit circuits as display connection terminals. A gate is connected to take out the copy start signal sent to the hard copy machine side, and each of the unit circuits detects the copy start signal sent from the display device connected to it, and inputs this signal to the flip-flop circuit. A setting circuit that outputs a set signal, but does not output a set signal if a screen operation prohibition signal based on the copy operation of another display device is input before inputting a copy start signal, and a setting circuit that outputs a set signal from the setting circuit. It inputs and outputs the copy enable/disable status from one output terminal as a copy enable signal, and outputs a reset signal to other unit circuits from the other output terminal, and when a reset signal from another unit circuit is input, copy It is equipped with a flip-flop circuit whose enable state is released, and a transmission circuit which receives a copy enable signal from the flip-flop circuit and transmits a screen operation prohibition signal and an image reading signal from a hard copy machine to a display device that performs a copy operation. A connector for hard copy machines featuring:
