Image data filing apparatus

An image data filing apparatus, comprising:

• a main device having a plurality of recording/reproducing units, each of said recording/reproducing units recording at least one of a plurality of image data of at least one of a plurality of documents to one of a plurality of recording media set therein and reproducing said image data from said one recording medium, said main device having media-changing means provided with a stack unit for stacking said recording media, and a carrier unit responsive to control means for performing a carrying operation of carrying one of the recording media between said stack unit and said recording/reproducing units;
• a terminal device connected to said main device and communicating control data and said image data therebetween to cause said main device to perform at least one of recording said image data to a recording medium and reproducing said image data from a recording medium;
• a plurality of buffer memories within said main device for temporarily storing said image data to be recorded in a recording medium or said image data reproduced from a recording medium;
• said control means responsive to a first request from said main device and a second request from said terminal device within said main device for controlling the recording and reproducing of image data and simultaneously performing both of said first and second requests, said first and said second requests each causing said control means to perform one of transferring image data from said buffer memories to one of said recording/reproducing units and transferring image data from another of said recording/reproducing units to said buffer memories;
• and
• means for inhibiting a carry operation with respect to one of the recording media associated with one of said first and second requests while the recording media is already in use in connection with the other of said first and second requests, whereby one of said first and second requests does not interrupt the other of said first and second requests, said means for inhibiting controlled by said control means.
