Abstract

PURPOSE:To furnish equal service to users by using one encoder by means of time division to sequentially use plural page memories and printers, and printing plural documents approximately simultaneously. CONSTITUTION:A system controlling part 8, first, controls a distributor 3 to control the page memory 4, and checks whether or not a page to be printed in the printer 6 is present in a data storing part 1 by referring to an internal table incorporated in itself. In case it is not present, the part 8 checks whether or not a document that is already received and not yet printed is present in the part 1, and in case it is present, registers it in the internal table as a document to be printed in the printer 6. A signal line 10 is supervised until the printing of the printer 6 ends, and after the said ending, a picture information is written in the page memory 4 via the distributor 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] Conventionally, this type of storage facsimile machine has had only one printer.

Therefore, if two or more received documents are stored, the second document cannot be printed out until after the first document has been printed. Especially if the first document has many pages,
Since the recipient of the second and subsequent documents is kept for a long time, the service to the recipient is impaired.

The object of the present invention is to eliminate these drawbacks.

[Means and operations for solving the problem] The storage type facsimile receiving apparatus of the present invention includes means for storing compressed data of received documents.

a decoder connected to the storage means; a plurality of memories connected to the decoder via the distributor and capable of storing one page of decompressed data; and a printer connected to each of the memories. It is characterized in that one decoder is used in a time-division manner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS [Embodiments] Next, nine embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which there are two printers. 1 is a data storage unit that stores compressed data of received documents.

For example, it can be realized with a disk. It is a decoder that expands the 2Vi compressed data, and 3 is a distributor that distributes the expanded data (image signal) to the page memory 4 or Fi5.

6 and 7 are printers connected to the 4-day memories 4 and 5, respectively, and 8 is a system control unit that controls the entire apparatus.

Signal lines 10 and 12 are signal lines that indicate the status of the printer 6 and the printer 7, respectively, with 2-bit codes indicating the printable status and printing status.

Indicates that the next page cannot be printed due to recording paper being ejected, etc. Signal lines 9 and 11 are signal lines for instructing the printer 6 and the printer to print, respectively.

The operation will be explained below according to the flowchart shown in FIG.

The system control unit 8 first controls the distributor 3 to select the page memory 4, and then refers to an internal table in the system control unit 8 and determines whether there is a page in the data storage unit 1 to be printed to the printer 6. Find out whether or not.

If the document does not exist, it is checked whether there is a received but unprinted document in the data storage unit 1.

If the document exists, it is registered in the internal table as a document to be printed by the printer 6. Next, the signal line 10 is continuously monitored until the printer 6 is no longer printing, and if the printer 6 is not printing, the decoder 2
is operated to decompress the compressed data and write the image information to the page memory 4 via the 9-distributor 3. After the writing is completed, the signal line 10 is monitored to see if the printer 6 can print, and if it is, the printer 6 is instructed to start printing via the signal a9. When the printer 6 receives an instruction to start printing, it sequentially extracts image information from the page memory 4 and records it.

Next, the system control section 8 checks whether a page to be printed to the printer 7 exists in the data storage section 1 or not.

And if it doesn't exist.

It is checked whether there is a received but unprinted document in the data storage section 1, and if there is, the document is registered in the internal table as a document to be printed by the printer 7.

Next, after controlling the 2-way divider 3 to select the page memory 5, the signal f is output until the f-lintuff is no longer being printed.
It continues to monitor lJ12, and if printing is not in progress, the decoder 2 is operated to decompress the compressed data and the image information is written to the page memory 5 via the 9-distributor 3. After writing is completed,
monitors the signal line 10 to see if the printer 7 can print;
If printing is possible, the printer 7 is instructed to start printing via the signal line 11. When the printer 7 receives an instruction to start printing, it sequentially extracts image information from the page memory 5 and records it.

Next, the distributor 3 is controlled again to select the page memory 4, and thereafter the above-described sequence is sequentially repeated.

〔Effect of the invention〕

As described above, the present invention prints multiple documents almost simultaneously by using one decoder in a time-sharing manner and sequentially using multiple printers. Therefore, there is an effect that equal service can be provided to multiple document recipients.
