When receiving procedure is completed, the main controlling section 91 starts preparation to transmit picture information. The main controlling section 91 controls network controlling section 6 to connect circuits, and gives instruction for operation to the storing section 3, and then, sends out picture information of the storing section 3 to a specified procedure circuit 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sending/receiving type facsimile device that performs half-duplex communication method I communication, and more particularly to a facsimile device having an image information storage device in its terminal.

[Technical background of the invention]

Generally speaking, a facsimile machine that is used for both sending and receiving uses only one line.
Since it is connected only by line, it is not possible to send while receiving. Therefore, in many conventional facsimile machines, no transmission operation can be performed during reception. In addition, with facsimile machines that can perform sending operations even while receiving, prepare a special form (for example, OMR form) on which necessary information is written, and during reception, send the original document along with this form. The document was configured so that it could be set at the reading position - ζ, and it was configured so that the transmission operation was permitted during reception and the transmission original could be set at the reading position without using any special paper.

In addition, when a facsimile machine equipped with a conventional image information storage device attempts to send a message to multiple recipients at once, or performs a so-called circular transmission, the recipients are automatically called one after another, so all communications are interrupted. Until this is completed, there will be very few lines available. Therefore, in many cases, other sending operations were not possible at all. In addition, facsimile machines that can perform transmission operations even during broadcast transmission are configured to use special paper as described above, or are configured to temporarily stop broadcast transmission and send the final draft to be sent during that time. Met.

[Problems with background technology]

However, as mentioned above, in devices where no transmission operation can be performed during reception, once the reception operation begins, it is usually not known how many originals will be sent from the other party. Furthermore, even if you know the number of sheets to be sent, you do not know how long it will take. Furthermore, in the case of a terminal that is used in a very large amount, it is not uncommon for the next reception to start immediately after one reception ends. Therefore, when trying to transmit using such a device, the free time of the device is very limited.
You must always monitor your free time.

In addition, as mentioned above, Is.
In such devices, the original to be sent remains set at the reading position, so the original cannot be taken home immediately. Therefore,
If you wish to use this original for another purpose, you cannot set this original at the reading position while this device is receiving data.

Next, during broadcast transmission (for devices that cannot perform broadcast operations, it is not easy to know the time required for the entire communication, so it is necessary to constantly monitor that the device is free. Even with devices that allow sending operations during transmission, the original cannot be taken home immediately, as described above.Furthermore,
Even in devices that can temporarily stop broadcasting,
If the next transmission document is also a manuscript for circular transmission, there is a problem in that operational efficiency is reduced due to the temporary suspension of circular transmission.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine that is used frequently but can reduce waiting time for an operator as much as possible when there is a document to be sent, and has high operational efficiency.

:) [Summary of the invention] 15. In order to achieve the above object, the present invention
) During the operation or even during the transmission operation, the transmission document is read, the read transmission image information is stored in the storage means, and when the reception operation or transmission operation is completed,
The transmitting image information transmission operation is automatically started.

Embodiment of the Invention FIG. 1 is a block diagram showing the configuration of a portion of a facsimile machine according to an embodiment of the invention.

This device includes a reading section 1 that reads a document (not shown), an encoding section 2 that encodes original image information, a storage section 3 that stores encoded image information, and a storage section 3 that stores decoded original image information. A recording unit 4 that prints on recording paper, a decoding unit 5 that decodes the encoded image information and returns the original image information, and a network control unit 6 connected to the line 7 that performs operations such as transmission. It is comprised of an operating section 8 and a control section 9 that controls each of the above-mentioned sections.

The control section 9 includes a main control section 91 consisting of a microcomputer, and reading control sections 9 for controlling the reading section 1, encoding section 2, storage section 3, control section 4, and decoding section 5, respectively.
2. Encoding control section 94, storage control section 96, recording control section 9
3, and a decoding control section 95.

The main control section 91 controls the reading control section 92, the encoding control section 94, and the storage control section 96 according to a preset control procedure.
, the recording control section 93, the decoding control section 95, and the network control section 6.

Next, the main control unit 91 controls the operation of the device configured as described above.
This will be explained according to the control procedure.

During standby, the main control section 91 detects by means of the network control section 6 that a reception operation should be started, and starts a facsimile control procedure through the network control section 6. At this time, when the main control unit 91 enters the procedure for receiving the encoded image information, first the decoding control unit 91
5, an operation instruction is given to the decoding unit 5. Subsequently, an operation instruction is given to the recording section 4 through the recording control section 93.

Therefore, the received image information flows through the line 7, the network control section 6, the decoding section 5, and the recording section 4 in this order, and is printed on recording paper.

Now, as described above, when a document is set on the reading section 1 and a transmission operation is performed using the operation section 8 while image information is being received from the line 7, the main control section 91 controls the reading control section 92. Through this process, operation instructions are given to the reading section 1. Subsequently, an operation instruction is given to the encoding unit 2 through the encoding control unit 94. Furthermore, the storage control unit 96 issues operational instructions to the reading unit 1, encoding unit 2, and storage unit 3. Therefore, the transmitted image information flows in the order of the reading section 1, the encoding section 2, and the storage section 3, and is stored in the storage section 3ζ.

In this way, the received image information and the transmitted image information flow simultaneously inside the device. In this state, the reading section 1 to the encoding section 2, the decoding section 5 and the recording section 4, the encoding section 2 to the recording section 3, and the network control section 6 to the decoding section 5 are connected by the same wire. Because it is connected, the main control unit 9
1 is controlled so that the transmitted image information and the received image information do not collide by dividing each connection in time.

Now, the main control section 91 continues the facsimile control procedure.
When the receiving procedure is completed, the line 7 is released. Subsequently, preparations are made to transmit the transmission image information stored in the storage section 3. First, the network control unit 6 is caused to generate a dial signal to the destination. If the destination is busy, wait a while and dial again. When the destination is dialed and the line is connected, the main control unit 9
1 instructs the storage unit 3J to operate through the storage control unit 96. The missing number ζ is passed through the decoding control unit 95 to the decoding unit 5
, and encoding control unit 94, respectively, give operation instructions to encoding unit 2#, re-encode in an encoding mode suitable for the destination device, and send the image to line 7 through network control unit 6. Send information. At this time, if there are still documents remaining in the reading unit 1ζζ, the flow of image information to the storage unit 3 is as described above. Further, at this time, the connections through which the image information flows are controlled by the main control as described above to prevent image information collisions.

Next, the transmission operation during broadcast transmission will be explained.

First, the main control section 91 causes the network control section 6 to dial the transmission destination. When the dial is established and the line is connected, the main control section 91 starts the facsimile control procedure. When image information transmission starts during the facsimile control procedure, the main control unit 9
1 puts the storage section 3 through the storage control section 96, the decoding section 5 through the decoding control section 95, and the encoding section 2 through the encoding control section 94 into an operating state. At this time, when a document is set on the reading section 1 and a transmission operation is performed on the operation section 8, the main control section 91 sends the original to the reading section 1 through the reading control section 92, and sends the document through the encoding control section 94 to encode the document. storage control unit 9 for unit 2.
Each operation instruction is given to the storage unit 3 through 6. In this way, the image information currently being broadcasted flows through the storage section 3, the decoding section 5, the encoding section 2, the network control section 6, and the line 7, and the newly transmitted image information flows through the reading section 1, the code The data flows to the converting unit 2 and then to the storage unit 3 in this order.

In this case, as described above, the operation is exactly the same as when the transmitted document still remains in the reading section 1 when reception is completed.

As explained above, the facsimile device of this embodiment has a configuration that can multiplex image information and send it within the device, so that it is possible to temporarily store the transmitted original even while receiving or sending a circular message. Can be done.

Note that the present invention is not limited to the above embodiments. For example, it is also possible to have a configuration that includes an encoding section and a decoding section for transmission, and an encoding section and a decoding section for storage.

〔Effect of the invention〕

As explained above, the present invention provides a facsimile device for both sending and receiving, which is equipped with an image information storage device, and is configured to be able to process image information in multiple ways within the device. However, by temporarily storing the transmitted document in the image information storage device, when it is desired to send the document, the operator does not have to wait as long as possible, which ultimately improves the operating efficiency of the facsimile machine. Can be done.

Further, the present invention can be applied to cases in which a facsimile machine performs a receiving operation while copying a document and temporarily stores received image information in an image information storage device, In addition, if the present invention is applied to a facsimile machine that has a function of locally connecting to other devices (for example, a word processor or a personal computer), it is possible to transmit or receive data locally at the same time as transmitting or receiving data using a line. becomes possible.
