Abstract

PURPOSE:To allow one decoding section to receive data simultaneously from plural lines without the need for the cost by not decoding the facsimile code data but storing the data in a picture memory under the control of a main control section when an incoming call reaches other line during the reception through one line. CONSTITUTION:Upon the receipt of an incoming call from a subscriber telephone line, a line control section 15 automatically closes the line and a G3 communications control section 13 controls the communication to receive facsimile code data. A decoding section 16 decodes the data by a command of a main control section 11 and a recording section 17 prints out the data. Upon the receipt of an incoming call from an ISDN line during the reception from the subscriber telephone line, an ISDN line control section 14 and a G4 communications control section 12 receive the call. The main control section 11 does not decode the received facsimile code data but stores the data in a picture memory 18 and allows the decoding section 16 to decode the data stored in the memory 18 after the end of reception by the control section 13 and allows the recording section 17 to print out the data. Thus, one set of the decoding section 16 is enabled to receive data simultaneously from plural lines without the need for the cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine having means for connecting to a plurality of communication lines.

[0002]

2. Description of the Related Art Two examples of conventional facsimile machines are shown in FIGS. 2 (A) and 2 (B). In the figure, 21 is a main control unit,
22 is a G4 communication control unit, 23 is a G3 communication control unit, 24 is an ISDN line control unit, 25 is a telephone line control unit, 26 is a decoding unit, 27 is a recording unit, and 28 is a buffer memory.

As shown in FIG. 2 (A), a conventional facsimile apparatus has a decoding section 26 for each connectable communication line. Alternatively, as shown in FIG. 2B, only one decoding unit 26 was provided.

[0004]

In the case of FIG. 2A, the above-mentioned conventional facsimile apparatus is provided with the communication lines to which the decoding section 26 can be connected, and therefore, the simultaneous reception from a plurality of lines is possible. However, there is a drawback in that the decoding unit 26 is expensive.

In the case of FIG. 2B, although there is a means for connecting to a plurality of lines such as an INS64 line and a subscriber telephone line, since only one decoding unit 26 is provided, the decoding unit 26 can be used with one line. When using, there is a problem that it is not possible to receive signals from other lines at the same time.

An object of the present invention is to solve such a problem, and in a facsimile apparatus having means for connecting to a plurality of communication lines, when a decoding unit is being used while receiving on one line, It is an object of the present invention to provide a facsimile apparatus that enables simultaneous reception from a plurality of lines when an incoming call is received on the line.

[0007]

SUMMARY OF THE INVENTION According to the present invention, in a facsimile apparatus having an automatic call receiving means and a means for connecting to a plurality of communication lines, a means for communicating with each communication line and decoding received facsimile coded data. Means and an image memory for accumulating the received facsimile code data, without decoding the facsimile code data when receiving on one communication line while receiving on another communication line,
The image data is stored in the image memory.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention. In the figure, 11
Is a main control unit, 12 is a G4 communication control unit, 13 is a G3 communication control unit, 14 is an ISDN line control unit, 15 is a line control unit,
Reference numeral 16 is a decoding unit, 17 is a recording unit, and 18 is an image memory.

In the facsimile apparatus having the above structure,
First, when an incoming call is received from the subscriber telephone line, the line control unit 15 automatically closes the line. Then, the G3 communication control unit 13 controls the communication, and the facsimile code data received thereby controls the decoding unit 1 according to the instruction of the main control unit 11.
The data is decrypted at 6 and printed out by the recording unit 17.

ISDN during receiving operation from the subscriber telephone line
When receiving an incoming call from the line, the ISDN line control unit 14 and the G4 communication control unit 12 receive the call. Since the reception has already been performed through another line, the facsimile code data from the ISDN line is stored in the image memory 18 without being decoded by the instruction of the main control unit 11.

When the receiving operation from the subscriber telephone line is completed, the facsimile code data received from the ISDN line stored in the image memory 18 is decoded by the decoding unit 16 according to an instruction from the main control unit 11, and is recorded by the recording unit 17. Printed out.

The same control is also applied when receiving from the subscriber telephone line while the ISDN line is receiving.

[0014]

As described above, according to the present invention, 1
When an incoming call is received on another line during a receiving operation on one line, the facsimile coded data can be received by storing it in the image memory without decoding. As a result, it is possible to receive from multiple lines at the same time without incurring the cost of having a plurality of decoding units, and it is possible to avoid the time when reception is not possible. In addition, it is possible to solve the problem that it is inconvenient because the reception in the G4 mode cannot be performed.
