Abstract

PURPOSE:To prevent the processing capability of a facsimile equipment from being deteriorated and to avoid poor service by implementing the succeeding dialing during the standby of recalling. CONSTITUTION:The recall processing is a processing to send picture information of a memory 3 stored in case of dialing processing and it is similar to the call processing except the absence of reading by a reader 1 and an encoder 2 in the call processing. On the other hand, when a call request comes when not in the state of timeout, the call processing is applied even during the recall standby. Thus, the processing in the sequential multiple addressing is quickened and since no succeeding calling wait takes place in the recall standby, the utilizing efficiency of the equipment is improved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a facsimile transmission device.

[Prior Art] Conventional facsimile machines temporarily disconnect the call when the other party's terminal is communicating, use a timer to wait for a re-call for several minutes, and re-call the same terminal after the above-mentioned several minutes. If the other party's terminal is in communication again when this re-call is made, the call is disconnected and the call is made again a few minutes later. This operation is repeated a predetermined number of times to prevent a situation in which one communication is impossible from occurring.

[Problems to be Solved by the Invention] In the conventional device described above, it is not possible to perform the next calling operation while waiting for a re-call. Therefore, if the user performs many outgoing calls while waiting for a re-call, the facsimile device may There is a problem that processing capacity decreases and service deteriorates.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine in which the processing capacity of the facsimile machine does not decrease while waiting for a re-call.

[Means for Solving the Problems] According to the present invention, the next calling operation is performed while waiting for a re-call.

[Operation] In the present invention, the next calling operation is performed while waiting for a re-call, so that the processing power of the facsimile machine does not decrease while waiting for a re-call.

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

This embodiment includes a reader 1 that reads an image, an encoder 2 that compresses and encodes the image data read from the reader 1,
A memory 3 that stores the compressed encoded data, a communication control section 4 that transmits the image information stored in the memory 3 to a destination terminal using a communication line, and a central control device 5 that controls the entire facsimile transmission device. have Note that the communication control unit 4 is in charge of the G3 protocol in the case of the 03 aircraft.

In the case of 64 aircraft, this is the part that controls the G4 protocol.

The central control unit 5 is an example of means for performing the next calling operation while waiting for a re-call.

Next, the operation of the above embodiment will be explained.

FIG. 2 is a flowchart showing the operation of the above embodiment.

First, the reader 1, encoder 2, memory 3, communication control unit 4, and central control unit 5 are initialized (si).
Then, it is determined whether re-calling is necessary (32).
Immediately after the power is turned on, there is no request for re-calling, so the process proceeds to S6. If there is a call request here, the call processing is performed (S7).
).

The above call processing is performed as follows.

That is, the reader 1 reads the image, the encoder 2 compresses and encodes the image information, and the communication control unit 4 stored in the memory 3 sends a connection request signal to the line to start communication with the other terminal. For example, the so-called G4 protocol based on protocols such as CCITT Recommendation T and 62 is used. If there is an affirmative response to the connection request signal, the compressed image data stored in the memory 3 is sent, a disconnection procedure is performed, and the communication is terminated. This also ends the call processing.

On the other hand, if there is a negative response to the connection request signal, the communication control unit 4 performs a disconnection procedure and ends the communication. and,
The status is changed to indicate that a re-call is required, and the call processing is terminated.

If it is necessary to call again in S2, it is determined whether the timer has started (S3), and if the timer has not started, it is started (S4), and it is determined whether the timer has timed out. (S5).

If the timeout occurs, a re-call process is performed (Sa). This re-call process uses the memory 3 stored during the above call process.
This process is the same as the call process, except that there is no reading operation by the reader 1 and encoder 2 in the call process described above. If the other party terminal is busy (communicating), the process returns to S2.

On the other hand, if there is a call request before the timeout has elapsed in S5 (36), the call process is performed even if the call is on standby (37).

In this way, the processing speed for successive notifications is increased, and there is no need to wait for the next calling operation while waiting for a re-call, so the efficiency of use of the device is significantly improved.

As mentioned above, perform the next calling operation while waiting for a re-call (
S7), when the calling process is completed, the process returns to S2, and if it times out (S5), a re-call process is performed for the busy partner terminal (Sa), so if another call is made while waiting for a re-call, Even if call processing is performed, re-call processing continues.

[Effects of the Invention] According to the present invention, there is an effect that the processing power of the facsimile machine does not decrease while waiting for a re-call.
