Abstract: In a system where fax messages are directed to a store and forward system when a fax machine is busy: When fax messages are stored and an attempt is made to re-deliver the message, an ID related to the serial number of the storage system is placed in the fax header. When a message is received by the store and forward system, the header is interrogated and if an ID related to the serial number of the receiving machine is detected, the fax is not again stored and the system notes that the transmission to the fax machine was not successful.

Abstract: A document processing apparatus that is adapted to the state of document data to be processed and performs document processing at low cost and efficiently. When document data comes over a communication line, a communication section receives the same to pass the received document data to a storage location selector. If the total size and the number of documents received are less than the predetermined values, the storage location selector transfers the document data to a part of the main memory. If the storage location selector cannot transfer the document data to that part, the storage location selector transfers the document data to one of auxiliary memories. The document data stored in one auxiliary memory is read by the CPU to be processed by the same and an image processor. The results of the document processing are stored in the main memory to be transferred to an output unit over an input/output interface 10 to be recorded.

Abstract: An image forming apparatus which stores image data of an image of each page of an original document into a memory and then outputs the image data stored in the memory in order of pages of the original document to record the corresponding image on a recording medium for producing a requested number of sets of copies of the original document. A controller determines, each time after image data for one page of the original document is stored in the memory, whether or not the memory will overflow if image data of a next page of the original document is stored in the memory. The controller prohibits reading of an image of the next page of the original document when it determines that the memory will overflow.

Abstract: A facsimile machine stores log information pertaining to facsimile transmission and reception in a facsimile RAM. To output a facsimile management report, log information items are read one by one from the RAM. It is then determined whether the read out log information meets a specific condition. Only log information which does not meet the specific condition is stored in a printer RAM and then printed by a printer. Thus, by taking a condition of log information not needed by the operator and inputting it as the specific condition, for example, log information not desired to be printed can be left out of the printing process.

Abstract: Image data generated by a reading section to perform copying is outputted to a recording section and, when a facsimile communication is received during such copying, received image data is temporarily stored in an image memory. Meanwhile, an amount of the received image data stored in the image memory is monitored so that, when free capacity of the image memory becomes less than a permitted level, copying is interrupted and operation for copying is switched to operation for outputting the received image data in the image memory through the recording section. Thus, a certain amount of capacity is always available in the image memory and vicarious reception errors due to a memory overflow during copying is eliminated. When the received image data in the image memory has been printed out by the recording section to such an extent that the free capacity in the image memory becomes sufficient again, the interrupted copying is restarted. Thus, copying can be performed without unnecessary delay.

Namely, when the reception of the page recorded in the memory hold mode is not yet completed and the remaining capacity of the image memory reaches below a predetermined capacity, the recorded memory blocks are released and the release mode is switched to the memory release mode.

Abstract: A facsimile apparatus and a facsimile communication method prevent the termination of communication in error due to memory capacity shortage when confidential communication or relay designation communication is effected by using a sub-address additionally recommended by the CCITT/T.30. When a remaining capacity of an image memory is smaller than a preset threshold, sub-address control information representing the invalidity of the sub-address is stored in sub-address control memory means. As a result, when an initial identification signal or a send command signal is sent to a destination station, a bit indicating that the sub-address is valid is sent without being set. Namely, the invalidity of the sub-address function is informed to the destination station. Thus, the confidential reception or the relay designation reception using the sub-address is not accepted and the termination of the communication in error due to the memory capacity shortage is avoided.
