Abstract

PURPOSE:To eliminate the need for a specific operation at a facsimile device, by counting the number of subscanning lines of a picture signal and processing an original exceeding a prescribed line number as a series of a plurality of originals. CONSTITUTION:A storage control section 10 detects a facsimile communication call from a facsimile device to perform a call set procedure and starts one of facsimile control sections 901-90n. The facsimile control sections 901-90n manage the length of screen of an original by counting the number of subscanning lines of the picture signal at the reception of the picture signal, and when the length exceeds a prescribed length, a screen section code is inserted and the result is stored as a separated picture signal. When the end of the picture signal is dtected, a message post-processing is executed and the end of operation is informed to the section 10. The storage control section 10 executes the call restoration procedure through an exchange interface section 8.

が増大する等の欠点がある。FIG. 1 shows a signal system when communicating multiple documents between facsimile machines that can only communicate one document in one facsimile procedure. In FIG. 1, reference numeral 1.2 indicates an analog facsimile machine for a telephone exchange network, 1 is a calling side, and 2 is a called side. 3 is an exchange. From the off-hook dial signal a to the on-hook f of the facsimile machine 1 is one facsimile call, and from the phase signal C to the image signal e is one facsimile procedure. Communication of a plurality of documents between the facsimile machines 1 and 2 is realized through a meeting between operators over the phone. For this reason, facsimile communication calls between facsimile machines and store-and-forward devices require an alternative to telephone calls, and even in this case, long documents must be made into multiple documents with limited document lengths, and complicated operations are required.1 , there are disadvantages such as increased line holding time.

変換蓄積方式。In a facsimile signal storage and forwarding method in which image signals from a facsimile device are temporarily stored in the system and sent to a specified destination, the storage and forwarding method is used when communicating between a facsimile device and a storage and forwarding device, where there is no limit to the length of the communication document for a facsimile communication call. When receiving and accumulating image signals, the device counts the number of sub-scanning lines of the image signal, and if it exceeds a certain value, it inserts a screen delimiter code and divides the image signal into one image signal consisting of a series of separated documents corresponding to multiple documents. When transmitting a stored image signal to be stored as a facsimile communication call and transmitted to the facsimile machine, the screen delimiter code is detected and a series of separated multi-image signals of 1 facsimile + J communication call is combined into one long document. A facsimile signal conversion and storage method that is characterized by transmitting it as a compatible image signal.
