PURPOSE:To attain smooth data communication, by performing recording from picture information having higher priority, storing information having lower priority in a storage device, and reading out it afterward and recording it to prevent collision in stations. CONSTITUTION:When a print request comes during the execution of a local copy, whether or not the copy under execution is finished is discriminated from a copy counter memory of an RAM. When finished, a switching signal K1 is brought into H level so as to transmit only picture information of a transceiver 2-3 to a printer PC and the recording is started. When not finished, the switching signal K1 is brought into H level so as to transmit the picture information of the transceiver 2-3 to the printer PC, an AND circuit 10 is opened, a switching signal K3 is brought into L level so as not to transmit the information of a reader RC to the printer, an AND circuit 12 is closed, a switching signal K5 is brought into H level to store the information to a recorder 6 and an AND circuit 13 is opened. Thus, the remaining picture information of the local copy is stored in the recorder 6 and priority is given to the recording of picture information supplied from other stations. |
