Abstract

PURPOSE:To recover part of a picture data or a control data even if the data is destroyed due to any cause by providing the 2nd means storing the picture data and the control data in parallel with a means storing the picture data and the control data so as to back up the data in a disk. CONSTITUTION:A data read by a scanner 11 is coded by a CODEC 13 and the data is stored on disks 15, 16 via a storage controller 14. Then a line control section 17 reads out the data from the disk 16 via the storage controller 14 and sends it to an opposite facsimile equipment. In the case of the reception, the line control section 17 receives a picture data from the opposite facsimile equipment and stores the received data onto the disks 15, 16 via the storage controller 14 respectively. In this case, if any error takes lace in the content of the sent data or the decoded data, the CODEC 13 reads out the data stored on the disk 16 via the storage controller 14 and sends or decodes it.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile machine, and in particular, to a facsimile machine having a storage function.
) regarding backup of data.

BACKGROUND OF THE INVENTION Conventionally, facsimile machines of this type have not stored data in parallel.

``Problems to be Solved by the Invention'' Conventional dual facsimile machines do not store image data and control data in parallel, so if part of the image data or control data is destroyed for some reason, The drawback is that it cannot be restored.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new facsimile apparatus which eliminates the above-mentioned disadvantages inherent in the conventional technology and which makes it possible to improve the reliability of the apparatus.

Means for Solving the Problems In order to achieve the above object, a facsimile apparatus according to the present invention includes a first storage means in which image data and control data are stored, and a second storage means having the same storage contents. and means.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 does not show one embodiment of the present invention and is a diagram of a flock 114.

Referring to FIG. 1, reference number 11 is a scanner (5CA
N) and reads the original. Reference numeral 12 denotes a printer (PRNT), which prints image data 1 to 1.

13 is a codet for encoding and decoding data. Reference numeral 14 denotes a storage controller (CONT), which controls writing data to the disk and reading data from the disk. 15 and 16 are disks (DISK) for data storage. 17 is the line control unit (CCII)
and transmits and receives image data.

Next, the operation of transmission and reception according to the present invention will be explained as an example.

In the case of transmission, first, the scanner 11 reads the document. Next, read it with the scanner month] l'! i! The captured data is encoded by a coach 13. The encoded data is stored together with its control information via disk 15 and storage controller 14. At the same time, the same data is also transferred to the disk 16 via the storage controller 14.
is stored in Thereafter, when connected to the destination facsimile by the line control section 17, the line control section 17 reads data from the disk 15 via the storage controller 1'T7-ra 14 and transmits it to the destination facsimile. At this time, the line control unit 17 determines whether the data cannot be sent from the disk 15 or there is an error in the transmitted data during communication with the other party's facsimile, and the error is caused by the error or the data read from the disk 15. If it is determined, the line control section 17 reads out the same data stored on the disk 16 via the storage controller 14 and transmits the data to the other party's facsimile.

In the case of reception, first, the line control section 17 receives image data from the other party's facsimile machine, and stores the received data on the disks 15 and 16 via the storage controller 14, respectively. When the storage on the disks 15 and 16 is completed, the contents of the disk 15 are read out via the coach 13 or the storage controller 14, and the read data is decoded.

At this time, if an error occurs in the contents of the disk 15 such as a decoding error in the coach 13, the coach 13 reads the same data stored on the disk via the storage controller 14 and restores the data normally. The decoded data is printed once it has been decoded.

As described in detail, according to the present invention, when data is written to a disk during facsimile transmission or reception, by always having another disk for backup, it is possible to prevent failure of one disk. However, by using other disks, the reliability of the device can be improved.

[Brief explanation of the drawing]

FIG. 1 is a block diagram showing one embodiment of the present invention.

Claims (1)

[Claims] an accumulation control means for reading or receiving a document and accumulating image data and control data; a means for accumulating the image data and control data; and a printing or transmitting operation for reading out the accumulated image data and control data. What is claimed is: 1. A facsimile apparatus having means for performing the above-mentioned facsimile apparatus, characterized in that the facsimile apparatus has second means for accumulating the same data in parallel with the accumulating means.
