Abstract

PURPOSE:To improve the compressing efficiency of transmission/reception data and to attain facsimile communication effectively, by compressing the transmission data read in a reading section, storing it in a storage section directly, reading out the data and giving it to a data compressing and reproduction section of a main body. CONSTITUTION:The transmission data read at an original reading section 1 of a facsimile main body A is compressed at a data compressing and reproducing section 7 of a data storage device, B, and the data is stored in the data storage section directly. In transmitting the stored data to a device of remote location, a switch S1 is changed over to the b-contact, the data in the storage section 6 is reproduced at the reproducing section 7, and aplied to a data reproducing and compressing section of the main body A, where data compression suitable to the device of the remote station is performed. The data is transmitted to the device of remote location via a modulation and demodulation section 4 and a network controlling section 5. In storing the transmission data from the remote device in a picture recording section 2, switches S1, S2, the main body A and the storage device B are used, to improve the compressing rate of transmission and reception data.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides data storage 4! l! Concerning a highly capable facsimile system.

In general, data is stored in a uniform storage device in order to enable long-term report, automatic night transmission, page 8 transmission, etc. at the time of transmission, and to enable proxy reception in the event of a failure of the image recording unit at the time of previous reception. For facsimile systems that have a data storage function that allows data to be stored, sent, and received, a major challenge is how efficiently sending and receiving data can be stored in the storage device. There are 9.

Conventionally, as shown in Fig. 1, in a facsimile system with a high data storage capacity, the data extracted by the 1jciFI 4 mode retrieval unit is transferred to the data pressure m reproducing section of the facsimile main body. 3, and then stored in the storage device 16, and at the time of reception, the network control s5 demodulates the data in the n1 modulation/demodulation unit 4, and stores the data before playback in the storage device 6, and transmits it. In this conventional facsimile system, the data is stored in a compressed state both at the time of reception and in a compressed state. If the data has been compressed by the data compression/reproduction section 3 of the facsimile main body, and the data is extracted from the storage device 6p for transmission, if the pressure mode is not compatible with the recipient machine. Transmission becomes impossible, and if the transmission rate is different, it is necessary to perform operations such as verifying and removing dummy bits from the correction partner, or adding them to dummy bits as appropriate. However, the drawback is that only compressed data can be handled, and operations such as editing the transmitted data are difficult to perform.

The present invention has been made with these points in mind, and is
A facsimile system having a data storage function that can optimally store data during sending and receiving without interfering with facsimile communication, taking into consideration the usage of data storage during reception f6. It provides:

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the facsimile system according to the present invention, 1!2
As shown in the figure, original S reading section 19 image recording section 2. The data compression/reproduction section 3 stores the transmission data read by the facsimile main body side system and the document reading section 1, which consists of the modulation/demodulation section 4 and the network control section 5. It is composed of a data storage section 6 provided to store demodulated received data and a storage device IIB consisting of a dedicated data compression/reproduction section 7.
It is now possible to manually switch between keys to output the received data from the storage device B.

The operation of the facsimile apparatus according to the present invention constructed as described above will be explained below.

If two lines of 181g data are to be accumulated, the data read by the gland@reader l is sent to the data compression/reproduction unit 7 on the storage device side B, where it is processed, and then ti+Iir is sent to the data storage unit 6. Ru. In addition, if the stored data Y is to be sent to the other party, the switch 5IYb is closed, the data is read out from the data storage section 6, and the data compressed and reproduced by the data compression and playback section 7. The data compression/reproduction section 3 is inserted into the slot, and the data is compressed in friend mode in the companion mode. The tuning box is then fed through the mesh control part 5. At that time, the storage device side B
The compression in the data compression/reproducing unit 7 is performed only for data storage and has nothing to do with facsimile communication, so the data compression is performed without any consideration of the circumstances of the other party's machine.
It is practical to use a data compression method to increase the storage efficiency 4 in the data storage unit 6 to the above ratio. Note that when sending the f'L data read by the original reading section l to the storage device side B, the same data is also given to the data compression/reproduction section 3 of the facsimile main body @A. In this case, a system control device (not shown) will perform selection control such that only the storage device @B is put into the active state and the data compression/reproduction section 3 is put into the small operation state. In addition, at this time, the storage device m1QB and the data compression/reproduction section 3
Needless to say, control is taken as necessary to put both in the operating state and to store the data in the storage device side IB instead of transmitting the same data.

Next, when accumulating received data, if you simply try to accumulate injury data in the opposite direction to the data accumulation and transmission route at the time of transmission as described above, the line will be overtaken and the other party's machine My friend, the data sent from the sender is sent continuously regardless of the status of the receiver,
As the data compression/reproduction unit 7 in the storage device @B, it is necessary to use a unit that can compress the manual data for each line in the main scanning direction at the speed promised in the control procedure. As a result, the power of facsimile communication was subject to restrictions.

That is, the data compression/reproduction section 3 of the facsimile main body MA
The line information being reproduced by the storage device 9411B and the line information being compressed by the data compression/reproduction section 7 of the storage device 9411B do not match, and one or several lines are lost due to the buffer between them, making compression and reproduction time-consuming and complicated. When simple line information follows next to rain information, if the data compression IIA reproducing unit 7 takes time to compress the data, the next simple line information will be omitted. Even the data compression/reproduction unit 7 of B is required to be capable of compressing data at the speed specified in the facsimile communication control procedure.

Therefore, when the present invention stores the received data, the damaged data Y which is damaged by the network control s5 and demodulated by the modulator W4 section 4 is directly stored in the data storage section 6 of the storage device IL-B. I am trying to send it to them and accumulate it.

In this case as well, selection control is performed by the system control device (not shown) so that only the storage device @B is in the operating state wA.

Therefore, when storing received data, the data compression/reproduction s7 in the storage device IIB is no longer involved, and as mentioned above, the compression speed Y% promised in the communication control procedure is maintained. There is no need to use any other equipment. Friend, when creating an image layout based on the injury data stored in the data storage unit 6,
When the switch blade contact 111 is closed, the data read from the data storage section 6 is sent to the data compression/reproduction section 3 on the side of the facsimile main body, where it is reproduced, and then the data is read out from the data storage section 6.
given to.

As described above, in the facsimile system according to the present invention,
In a 7t model that has a data storage function that temporarily stores the sending and receiving data in the data storage section, the sending 16 data that has been removed by the document reading section is compressed and stored in the data storage section, and the data storage section A storage-only data compression/reproduction unit is provided which reproduces the transmission data χ read out from the facsimile unit and supplies it to the data compression/reproduction unit S on the facsimile main body side, and also directly stores the demodulated and next received data in the data storage unit. Read from section t″
Send the injury data to your friend by faxing it to the data compression and reproducing section on the main unit.

It is possible to store received data efficiently in i/kiji without interfering with the facsimile transaction value, and it is also possible to independently handle transmitted data that has been reproduced in storage@. Dandan no Yu 7'L7
