Abstract

PURPOSE:To reduce the data quantity and to improve the processing capability of a facsimile store and forward exchange, by replacing the linear coded code given from a facsimile equipment with a memory address signal. CONSTITUTION:When a message is supplied to a facsimile store and forward exchange S/F6 from a facsimile equipment FAX5, the linear coded data fed from the FAX5 is supplied to a linear coded data analyzing circuit 21 of a circuit control part 3 via a circuit corresponding part CL. The circuit 21 decides whether the data P is equal to a make-up code or a terminating code and then identifies a specific address of a terminating code memory 22 or a make-up code memory 23 for the corresponding code. Then the relevant code is replaced with a memory address of 8 bits. Then an 8-bit memory address signal is stored to a recorder 4 from the part 3 via a CPU1 in the form of the picture information data. This reduces the quantity of the data P and improves the processing capability of the S/F6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an image information processing system for a facsimile storage and exchange machine.

(Prior Art) As a conventional facsimile storage/exchange machine (hereinafter abbreviated as 87F) image information processing method for facsimile messages, Fig. 1 (a)
), a facsimile terminal (hereinafter abbreviated as FAX) 5
The one-dimensionally encoded data shown in Fig. 1(b) is connected to the line corresponding section LA3 and the line control section (hereinafter referred to as L).
(abbreviated as CU) 2, central processing unit (hereinafter abbreviated as CPU) 1
The method was to store the data in the storage device M4 through the process. Therefore, if there are many black run lengths, such as in the case of telegrams where most of the lines are continuous black pixels (26 pixels or more) and the number of white pixels between black and white pixels is 29 or more, the code length becomes 12 bits. , 13-bit configuration has become common, and the amount of data to be stored in the storage device inevitably increases, leading to disadvantages such as an increase in the number of file accesses and an increase in the storage device capacity.

(Object of the Invention) The object of the present invention is to have an encoded data analysis circuit, a terminating code memory, and a make-up code memory in the S/F LCU, and to convert one-dimensional encoded data from a FAX into a terminating code memory address. It is an object of the present invention to provide an image information processing method which solves the above-mentioned drawbacks by replacing the make-up code with a memory address signal, transmitting it to the CPU, and storing it in a storage device.

(Structure of the Invention) According to the present invention, in a facsimile storage/switching machine that performs communication with a facsimile terminal using a one-dimensional encoding method by temporarily storing facsimile messages in a storage device, It is equipped with an original encoded data analysis circuit, a make-up code memory, and a terminating code memory, and replaces the one-dimensional encoded data from the facsimile terminal with a make-up code memory address and a terminating code memory address signal in the facsimile storage and exchange. An image information processing system for a facsimile storage and exchange machine is obtained, characterized in that image information is stored in the storage device of the facsimile machine.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 2(a) is a block diagram of an embodiment of the present invention, and FIG. 2(b) is a block diagram of an embodiment of the present invention.
is an example of one-dimensional encoded data from a FAX, (c) is an example of data stored in the ld storage device, and FIG. 3(a) is a configuration diagram of a memory address signal input to the storage device. (b) and (c) show configuration diagrams of examples of the terminating code memory and make-up code memo in FIG.
In FIG. 2(a), 1 is a central processing unit CPU, 2 is a line control unit LCU13 is a line correspondence unit LA, 4 is a storage device M, 5 is a facsimile terminal FAX, and 6 is a facsimile storage/exchange S/F.

Now, considering the case where a facsimile message is input from FAX5 to S/F5, LCLT2 from FAX5 to S/F5
Figure 2 is one-dimensionally encoded in F A, X 5 (
Data P shown in b) is input. Here LCUZ
The one-dimensional encoded data analysis circuit 21 determines whether the input data P is a make-up code or a terminating code, and the corresponding code is stored in a terminating code memory 22 or a make-up code memory 23.
Figure 3(a)
Replace with the 8-bit (fixed length) memory address signal shown in .

In addition, the code at position 27 in FIG.

Then, the memory address signal 8 of the 8 billets is sent as image information data from the LCU 3 to the storage device M4 via the CPUI.
Store in.

On the other hand, when sending image information from S/F (i to FAX5),
The data transferred from the CPUI to the LCU2 is the address signal of the terminating code memory or the address signal of the make-up code memory stored in the storage device [M4, and the LCU2 transfers the terminating code memory 22 to the make-up code memory according to the received address signal. Up sign memory 2
3, the one-dimensional encoded data is read out and sent to the receiving facsimile line.

(Effects of the Invention) As explained above, the present invention replaces the one-dimensional encoded code from the FAX with the memory address signal to reduce the amount of data, improve the processing ability of the S/F, and reduce the storage capacity. It has the effect of producing
