Abstract

PURPOSE:To obtain a simplified device, by identifying an outgoing call identification signal issuing from an opposite device at the time of arriving an incoming call, and switching a circuit to a facsimile equipment side, or a personal computer communication equipment side. CONSTITUTION:By supplying a retrieval command to a personal computer 2 by an operator, the computer 2 issues an outgoing call operation instruction to a personal computer communication control equipment 3, and a network control circuit 6, by changing over a fine changeover switch 7. The circuit 6 starts an outgoing call operation, and at the time of closing the circuit, the equipment 3 starts an outgoing call communication. And the communication of a bit of retrieval information is performed between the said terminal equipment, and the opposite equipment. Afterwards, in case of performing the reception of a bit of picture information regarding an object to be retrieved, the opposite equipment performs a facsimile outgoing call communication. A call identifier 5 in the terminal equipment detects the outgoing identification signal, and informs it to the computer 2. The computer 2 switches a switch 7 to a facsimile equipment 4 side, and also, supplies an incoming call operation instruction to the equipment 4. Meanwhile, the same operation as in retrieval is applied correspondingly in a registration operation.
