Abstract

PURPOSE:To attain the transmission of number of originals in excess of file capacity with one operation by reading remaining transmission originals and storing picture data of the said remaining transmission originals to a transmission file after a control section transmits a picture data of the said transmission file when the transmission file is occupied by the picture data. CONSTITUTION:When one page's share of original read is finished, and a picture data converted for one page's share is stored to a transmission file, a CPU32a obtains a detection output of an original sensor 30g via a mechanism driver 32e, detects whether or not an original exists in a hopper 30a, and when no original exists, the reading of one communication's share is completed and when any original exists, whether or not file-over exists is detected. That is, the CPU32a checks the remaining capacity of the transmission file at each storage of the picture data for one page's share. In case of the file-over where the remaining capacity of the transmission file is less than the maximum capacity of the picture data for one page's share or in case of the completion of reading for one communication's share, the CPU32a detects whether or not there is a ring signal (call) from a line via an NCU33a, and when a call exists, the receiving is conducted.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention stores image data obtained by reading a document in a transmission file memory, and then transmits the image data stored in the transmission file memory to a destination facsimile machine. The present invention relates to a facsimile transmission control method that enables a facsimile machine to transmit image data of an original in excess of the capacity of the file memory.

, [Technical Background] With the recent development of facsimile technology, facsimile machines that are inexpensive and have a variety of functions have been provided on the market, and facsimile machines are used in various fields.

These functions include broadcast communication that sends the same document content from one facsimile to multiple facsimiles, specified time communication that sends at a specified time, and inter-file transfer communication that enables high-speed communication. In all of these, the facsimile is equipped with a file for storing image data, and the image data that has been read is stored in this file, and then the image data of the file is transmitted.

[Conventional technology and problems]

The prior art will be explained with reference to FIG. 1, taking broadcast communication as an example.

The facsimile 1 includes an image memory 13 in addition to a control circuit 10 that controls the entire apparatus, an operation panel 12, and a document reading section 11, and a document DS read by the reading section 11.
After storing the image signals in the image memory 13, facsimile communication is performed. For example, in order to send a broadcast message to the facsimile devices 20, 21, . It is converted into image data according to the capabilities of the other party (transmission destination), temporarily stored in the image memory 13, and then transmitted to the destinations 20, 21, . . . 2n are sequentially called, and the image data stored in the image memory 13 is sequentially transmitted. The same is true for time-designated communication, in which the image data stored in the image memory 1.1 is sent out one after another at a designated time and transmitted to the designated destination. Also, in the case of inter-file transfer communication, the image data stored in the image memory 13 is transmitted to the image memory of the destination facsimile machine, thereby performing high-speed communication unrelated to sending and receiving operations.

In an image signal storage type facsimile that uses this image memory as a file, the storage capacity of the image memory 13 is not infinite but limited due to restrictions on device cost.

On the other hand, the capacity of the transmitted manuscript for - communication is not constant and may extend to a large number of sheets, and in this case, the transmitted manuscript image data for one communication may exceed the capacity of the image memory. For example, as compressed data using CCITT's MR method, a general document has a data amount of about 20 to 30 Kbytes, which is about 1.
With a temporary IC file size of about 500KByte-IMByte, the amount of memo IJW that can be used as a sending file is 5 to 500 KB in order to leave an area for reception.
There are about 10 pieces.

Therefore, when a larger number of originals is to be transmitted, the file storage capacity of the image memory 13 is exceeded, so that the file memory overflows and the transmission becomes impossible. For this reason, it is necessary to perform facsimile communication by limiting the number of original documents that can be input, and when there is a large number of original documents, it is necessary to perform facsimile communication in several batches, which poses a problem in that it takes time and effort for the operator. .

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile transmission control system having a transmission file that allows transmission of a number of original copies exceeding the file capacity in one operation without being limited by the file capacity of both memories.

[Structure of the invention]

Next, the operation of the embodiment configuration shown in FIG. 2 will be explained with reference to the processing flowchart shown in FIG.

■ The operator sends the original DS that he wants to send to hopper 30α.
, and then input the destination's abbreviated number or telephone number using the numeric keys on the operation panel 34.

This is given to the CPU 32α via the mechanical driver 32e and stored in the destination area AT of the RAM 32C. When performing broadcast communication, each destination to be broadcast is input.

(2) Next, the CPU 32α starts the document reading operation.

That is, the CPU 32α turns on the lamp 30e via the mechanical driver 32e, and turns on the drive roller 30C.
The document DS set in the hopper 30α is driven and sent out one by one by the feed roller 305, and sent to the stacker 30f at a predetermined sub-scanning interval. On the other hand, CPU32α
The photoelectric conversion element 31b or 3 is sent to the sensor amplifier 31C via the CPU 32h depending on the capacity of the other party (A4 size or 84 size).
Selectively operate the IC. The light reflected from the document corresponding to the irradiation position of lamp 3 (M) is reflected by optical lens 31α or 31d.
The image of each line of the document is input to the photoelectric conversion element 315 or 316 through the sensor amplifier 3 as an image signal and is read.
1C, amplified by sensor amplifier 31C and output to CP
Input to U32A. The CPU 32h compresses this image signal using the data compression method of the destination specified by the CPU 32α, that is, the MH (Modified Hoffman) or MR (Modified Read) method for the G model, and converts it into a facsimile image signal (image data). Convert to

The CPU 32b performs compression processing using the RAM 32C, and the compressed facsimile image signal is given to the CPU 32α. The CPU 32α sequentially sends this FAX image data to the expansion interface circuit 39α via the bus 32d, and stores it in the transmission file on the floppy disk i [39h].

In this way, the original is sequentially read and scanned, and when the image data of the first page of the original is accumulated, the second page of the original is sent out by the feed roller 30b, and the image of the original is read in the same way. The image data of the second page of the original is accumulated, and in the same manner as above, the originals set in the hopper 30α are sent out one after another, read, converted into image data, and accumulated in a transmission file.

■4 On the other hand, the CPIU 32α obtains the detection output of the document sensor 30g via the mechanical driver 32e every time one page of the document is captured and one page of converted image data is stored in the superstition file. , detects whether or not there is a document on the hopper 30α, and if not, it is determined that reading for one communication is completed, and if there is, it is detected whether there is a file over. That is, CPU32α
Each time one page of image data is stored, it checks the remaining capacity of the transmitted file based on the file management program built into its own read-only memory (ROM), and calculates the estimated remaining capacity of one page of image data. Detects whether the maximum capacity is exceeded. If the remaining capacity is equal to or greater than this maximum capacity, the process returns to step (2) to send out the next document from the hopper 30α and perform the reading operation in the same manner.

On the other hand, when the reading for one communication is completed or the remaining capacity of the transmitted file becomes less than the maximum capacity mentioned above, the CPU 32α detects whether there is a ringer (call) from the line via the NCU 33α, and If there is a call, a reception operation is performed.

In other words, if there is a facsimile call after the transmission file has been created but before the transmission starts, if you ignore this and start the transmission, the calling station will be forced to wait until the transmission is finished. Performs a receiving operation in response to a call. In this receiving operation, the received signal from the line is sent to NCU3.
3α and demodulated by the modem 33b, the CPU 32
α, stored in the RAM 32C, and further stored in the CPU 3
After the compressed image signal is converted into an image signal through condensation processing in step 2-'7, the signal is sent to the recording section 36, and the mechanical driver 32g drives the receiving mechanism section 35 according to a command from the CPU 32α to obtain a predetermined sub-scanning speed. The recording unit 35b records the received image signal while feeding the recording paper.

(2) If a ringer is not detected in step (2), or after a ringer is detected and the automatic reception operation is completed, the CPU 32α performs an automatic dialing operation and calls the partner station. That is, CPU3
2α retrieves the abbreviated number or telephone number of the destination stored in the destination area AT of the RAM 32C, indexes the corresponding telephone number if it is an abbreviated number, activates the automatic transmitter 33C with the telephone number, and automatically transmits the number of the destination. Make a dial call,
A calling operation is executed and sent to the line via the NCU 33α.

Next, the NCU33 ct detects whether the other party is basic or not, and if it is not basic, it proceeds to step ■, and
If it is LLsy, the CPU 32 (l is I) increases the number of calls made by the AM 32c to the corresponding partner station by "1", and detects whether the number of calls made reaches a limit number (for example, 20). If the number of calls is less than the limit, a timer is activated and the call to the station is automatically dialed again after three minutes have elapsed.

When this number of calls reaches or exceeds the limit number of calls,
asy (for example, the other station is out of order or the power is cut off),
As a result of the transmission failure, the transmission file on the floppy disk is canceled, the image data is cleared, and the process ends.

(2) On the other hand, if the line is not busy, the line is connected to the other station, the connection between the NCU 33α and the automatic transmitter 33C is switched to the connection between the NCU 33α and the modem 33A, and data transmission becomes possible. First, the CPU 32a exchanges control signals with the partner station via the modem 33b and NCU 33α according to predetermined pre-procedure control, and transmits image data after the pre-procedure sequence is completed. That is, C.P.
U32α controls the expansion interface circuit 39α,
Drive the floppy disk device 39b, read out the stored FAX image data from the transmission file on the floppy disk, send it to the modem 33A, modulate it, and send it to the NCU 33.
(The CPU 32α repeats this for the number of pages of the general manuscript DS, and when all the members have transmitted several minutes, the transmission operation for the transmission file is completed.

■ Next, CPU32α is R, AM32? destination area A
Check T and detect whether there is a next destination. If there is a next destination, it is a repeat communication request, so C
The PU 32α performs post-procedure control via the modem 33b and automatic transmitter 33C, disconnects the line with the current destination, and returns to step (3) for transmission to the next destination.

On the other hand, when there is no next destination, that is, one-to-one communication or broadcast communication has completed a round, the CPU 32d sends the output of the document sensor 30g via the mechanical driver 32e, and if it is determined that there is no document on the hopper 30α, sends the output to the transmission file. When all the image data of the original to be sent is stored in the file and sent (that is, the image data of the original within the capacity of the sending file is lost), the CPU 32α transmits the modem 33b and the automatic transmitter 33C to the current destination. The facsimile communication is completed by performing post-procedure control via the fax machine, disconnecting the line with the current destination, and completing the facsimile communication.

■ On the other hand, when it is detected that there is a document on the hopper 30α from the output of the document sensor 30g, the cpTj-32α determines that the number of documents exceeds the capacity of the transmission file, and picks up the remaining documents. Return to step ① to store and send the file. As a result, the remaining manuscript is read, stored in a transmission file, and transmitted to the destination in the destination area of the RAM 32C.

In this way, when sending a document that exceeds the capacity of the sending file,
In one-to-one communication, after the image data of the send file is sent, the line connection is maintained, the remaining original image data is stored in the send file, and after the send file is created, the image data of the send file is sent again. communication is completed. In addition, in broadcast communication, after the image data of the sending file is sent to each destination, the line is disconnected, the image data of the remaining original is stored in the sending file, and after the sending file is created, it is sent to each destination again in sequence. Connect the line and send the image data of the file to be sent.

In the above explanation, a floppy disk was used as an example of image memory for sending files, but well-known memory such as a semiconductor memory or a magnetic disk could also be used. The number of original pages is detected by the operator from the operation panel 34 in advance, and the CPU 32α manages the number of original pages stored in the transmission file, and the number of original pages is detected at the time of file over of the transmission file. The presence or absence of a remaining document may be detected from the above.

Although the present invention has been described above using one embodiment, the present invention can be modified in various ways according to the gist of the present invention, and these are not excluded from the present invention.

〔Effect of the invention〕

As explained above, according to the present invention, there is a reading unit that reads a document to be transmitted and outputs an image signal, an image memory that has a transmission file that stores image data, and a device that converts the image signal into image data. and a control unit that stores the image data in the transmission file and transmits the image data of the transmission file to a specified destination, and when transmitting image data that exceeds the capacity of the transmission file, the control unit stores the image data in the transmission file. is filled with the image data, and after transmitting the image data of the transmission file, the remaining transmission document is read, the image data of the remaining transmission document is stored in the transmission file, and the image data of the transmission file is read. This feature has the advantage that it is possible to send a number of original pages in a single operation that exceeds the size of the file to be sent, so the operator does not have to worry about the size of the file to be sent. Now you can send a facsimile just by setting the original on the machine, which makes the operation easier and allows you to send a facsimile in one time instead of sending it in two parts.
The operator does not have to wait until the first transmission is completed, since the trouble of having to perform the operation again after the first transmission is completed is eliminated. Therefore, even when performing time-specific communication, especially at night,
This can be done without requiring operator intervention. Moreover, since it can be realized without major modification of the device, it can be realized easily and at low cost, and facsimile machines that wait for the transmission file can be provided to the market at low cost.
Excellent in practice.
