BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory-to-memory communication method having an inter-storage device using a protocol (RPOTOCOL) in a facsimile (FAX), particularly among its own models having a memory.

Conventionally, in a facsimile memory-to-memory communication method, one-line coated data (ONE is used on the transmitting side according to the minimum required for one-line scanning on the receiving side (MINIMUM SCAN LINE TIME: hereinafter referred to as MSLT). If the number of -LINE CODING DATA is less than the minimum time (MSLT), the fill data (øBIT) is the same as the minimum time (MSLT) and transmitted to the receiver. .

Accordingly, the present invention has been made in order to solve the above-mentioned problems and to facilitate the user's convenience. For this purpose, a protocol (PROTOCOL) is used to transmit to a receive memory using a protocol between its own devices. In transmission, it reduces the communication time by transmitting only the fill data without filling fill data (MSLT = øm Sec) and reduces the overall communication time by using the data in the receiving memory after communication with the recorder. To provide a way to save.

A memory-to-memory communication method having a facsimile mutual storage device of the present invention having such a purpose will be described with reference to the accompanying drawings.

1 is a flowchart of a transmission side of the present invention. First, a document to be scanned is scanned by using a memory and coded in page units, and then the coding data is stored in the memory (1). To be implemented.

In this case, after performing the step (2) of receiving the protocol (Protocol) sent from the receiving side, the memory / memory (M / M) receivable information therein and the memory / memory (M / M) receivable note of the receiving side are determined. If it is possible to determine this in step (3), if it is possible to receive the data, check the remaining memory on the receiving side to determine whether the reception is possible in step (4). If transmission is possible in the protocol, the memory / memory transmittable information and MLSTøm Sec If the transmission is not possible in the step (3) or the transmission in the step (4) is impossible, the memory / memory transmission impossible information and the MLST in the protocol are transmitted to the receiving axis. Is sent to step (6).

The memory / memory transmission is divided into two types.

Firstly, when the multi-page transmission is performed, phase-D (PHASE-D) is performed for each transmission page, and secondly, the last phase-D is performed when the multi-page transmission is performed. This can be reduced by the time for performing D.

In addition, when comparing the remaining memory on the receiving side with the total page coding data on the sending side, memory / memory transmission is performed only to a reasonable page, and the remaining pages are normally transmitted. Secondly, in the case of multipage transmission, only the last page of the memory / memory transmission may perform phase-D. Here, the time for performing phase-D for each transmission page can be reduced.

Therefore, if memory / memory (M / M) transmission is possible, the memory / memory transmission information and MLST øm Sec are transmitted to the receiving side in the protocol. If memory / memory transmission is impossible, the memory / memory transmission information and MLST is not available in the protocol. Send the specified data to the receiver.

Therefore, in step (5), in order to reduce the data transfer time at the time of memory / memory transmission, transmission is performed to the receiving side with the memory / memory transmittable information and the minimum time MLST = øm Sec in the protocol PROTOCOL.

The information must be organized in a protocol.

2 is a flowchart of a receiving side according to the present invention, in which memory reception is possible in the step (7) of transmitting / receiving memory / memory reception in a protocol and remaining memory information to the receiving side in a state of retaining memory. In step (9) of determining whether to transmit the memory / memory (M / M) of the transmitting side via the step (8) of transmitting the available information and the remaining memory amount to the transmitting side and receiving the protocol (PROTOCOL) from the transmitting side. Determining whether the memory / memory of the transmitting side is transmitted to perform normal reception (11 ') if transmission is impossible, and if the memory / memory transmission is possible, determining the memory / memory reception (10). If memory / memory (M / M) reception is possible, the memory is received in the reception step 11, and if it is determined that the memory / memory reception is impossible, the general reception step 11 '. Standing performs normal reception.

The information must be organized in a protocol.

As described above, the present invention communicates a memory-to-memory having a facsimile mutual storage device. If the memory / memory (M / M) can be transmitted and received, the data will not be filled during data transmission. Because the data is transmitted without the data transmission time, the data transmission time is shorter than that of the general transmission, and the phase-D (PHASE-D) part that is performed on each page can be skipped, thereby reducing the overall communication time and reducing the communication cost. Has an effect.
