Abstract:
An information processing system, comprising:a plurality of information processing modules each for performing information processing, the information processing modules includes a copy module, a facsimile module and a printer module; storage means being installed in each of said information processing modules for storing display data; transmission request acceptance means being installed in each of said information processing modules for accepting a display data transmission request; recognition means being installed in each of said information processing modules for determining whether display data corresponding to the transmission request is stored on said storage means, wherein said information processing module also includes said transmission request acceptance means accepting the transmission request; transfer means being installed in each of said information processing modules for transferring the transmission request to a different module, if said recognition means determines that the display data corresponding to the transmission request is not stored on the storage means; display data getting means being installed in each of said information processing modules for getting the display data from said storage means, if said recognition means determines that the display data is stored on the storage means; and display data transmission means being installed in each of said information processing modules for returning the display data gotten by said display data getting means to an upstream information processing module making a prior transmission request to a downstream information processing module returning the display data; identification information notification means being installed in each of said information processing modules and sending identification information of display data that can be gotten in each of the information processing modules to all the other said information processing modules; identification information reception means being installed in each of the information processing modules for receiving the identification information of display data that can be gotten in the one of the information processing modules, sent by said identification information notification means; and identification information storage means being installed in each one of the information processing modules for storing the identification information of display data that can be gotten in the one of the information Processing modules, received at said identification information reception means.
