Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a busy processing method in a facsimile machine.

Conventionally, facsimile transmission has generally been carried out by placing a document on the paper feed section of a facsimile machine, calling the recipient by telephone, and connecting the line. However, if the other party is busy, it is necessary to keep dialing until the call is connected, which creates a problem for other users. Therefore, an efficient busy processing method is desired.

[Conventional technology]

Storage-type facsimile devices, which have become popular in recent years, have the storage device memorize the original and the called party's phone number, and use an automatic dialing function to repeat dialing at predetermined time intervals as a countermeasure against busy calls. .

In other words, you can either store document information in the storage device from the beginning and automatically send it (hereinafter referred to as file transmission), or perform normal transmission operation (hereinafter referred to as normal transmission), and if a call is busy, file transmission is performed. Busy processing can be performed by switching operations.

The functions and operations of a conventional storage type facsimile device will be described below with reference to FIG.

Reference numeral 1 denotes a control section composed of a microcomputer or the like, and controls each functional section through a bus line 100 according to a program stored in a storage section 9.

2 is read by the reading section 3, and the band compression section 4
This is an image signal storage unit (file) that stores the image signal of the transmitted original document that has been band-compressed in the image signal storage section.

The transmission operation will be explained below.

File transmission is performed by pressing the file transmission key on the operation unit 8. The read document information is stored in the image signal storage section 2, and the phone number of the destination of the document entered using the OMR sheet or numeric keypad is stored as the phone number. The information is stored in the automatic dialing section 15, and the automatic dialing section 14 calls and transmits a call to the other party.

That is, the control section 1 causes the automatic dial section 14 to issue a dial pulse through the network control section 13, and after establishing a line, transmits the image signal in the image signal storage section 2 through the transmission control section 10 and the modulation/demodulation section 11.

Normally, transmission is performed directly without going through the image signal storage section 2, and by pressing the document transmission key on the operation section 8,
When the telephone number of the other party is entered using the numeric keypad, the automatic dialing section 14 is operated, and after the line is established, reading of the document is started and transmission is performed.

In the above operation, busy detection is performed after making a call.
If there is no response after a predetermined period of time (for example, 30 seconds), it is determined that the call is busy, and in the case of normal transmission, a lamp or the like will notify the operator. At this time, the operator calls again or switches to the file sending operation using the operation unit 8. When sending a file, calls are automatically repeated at regular intervals until the line is established.

In the figure, 6 is a band expansion unit that restores the received signal, 5 is a recording unit that records and reproduces the received image signal, and 7 is a band expansion unit that restores the received signal.
1 is a drive unit that drives the reading unit 3 and the recording unit 5;
2 is a telephone.

[Problem that the invention seeks to solve]

Of the busy processing methods explained above, if all transmission is done by file transmission without normal transmission, the capacity of the storage device must be made extremely large; The method of artificially switching to file transmission had problems such as cumbersome operation.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, an automatic dialing device, a storage device, a means for detecting the busy state of the called party, and a means for reading the original when the busy state is detected, and reading the original and transmitting the original information and the called party. A means for storing a telephone number in the storage device, and a means for counting a certain period of time after a busy call is detected are provided. This can be achieved by the facsimile device according to the invention.

[Operation] When the other party is busy, the original information is read and stored in the storage device together with the other party's telephone number, and after a certain period of time, the original information is redialed based on the other party's telephone number and the stored original information is transmitted. According to the present invention, the process always starts with a normal transmission operation, and only when a busy state is detected, document information is automatically stored in the storage device and file transmission begins. Therefore, the sender can operate without being aware of the other party's line status, and
This has the advantage of not bothering other users.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1a is a block diagram showing a storage type facsimile apparatus according to an embodiment of the present invention, and FIG. 1b is a flowchart showing the operation and operation. Note that the same symbols in the figures represent the same objects.

In FIG. 1A, reference numeral 16 denotes a busy sound detection unit which detects a 400 Hz busy sound transmitted by the exchange and intermittent for 0.5 seconds when the other party is busy, and notifies the control unit 1 of an interruption.

The operation and operation will be explained according to FIG. 1b.

(1) The operator places the original to be sent on the original table, presses the original send key, and inputs predetermined information such as a telephone number using the numeric keys.

(2) The automatic dialing section 14 starts up and dials the other party.

(3) When the line is connected, the reading section 3 operates and the document is transmitted.

(4) When the busy sound detection unit 16 detects a busy sound, it switches to file transmission, reads the original and stores it in the image signal storage unit 2, and stores the telephone number etc. in the telephone number storage unit 15. , and after establishing a line by making a call at regular intervals, transmits the document information in the image signal storage section 2.

As described above, when a busy tone is detected during normal transmission operation, it is possible to automatically switch to file transmission.

In addition, if the line cannot be established because the line is not busy,
It is also possible to switch to file transmission after a certain period of time has elapsed.

Further, the telephone number storage section 15 can be included in the storage section 9, and the stored telephone number is linked to the document information in the image signal storage section 2.

〔Effect of the invention〕

As explained above, according to the present invention, only when a busy situation occurs during a normal transmission operation, the system switches to file transmission, so the capacity of the storage device can be relatively small, and it is less troublesome when a busy state occurs. It has the advantage of automatically switching to file transmission without any operations.
