Abstract

PURPOSE:To attain memory transmission succeedingly even when part of a read original is not stored in the memory. CONSTITUTION:When information of an original to be sent is stored in a storage memory 8, a storage discrimination section 9 discriminates whether or not a succeeding page of the transmission original is stored in the storage memory 8. When a transmission control section 4 discriminates that a succeeding page cannot be stored in the storage memory 8, the memory storage procedure so far is not interrupted but remaining originals are set to the memory standby state. When the information stored already is sent and the memory residual quantity is sufficient, the standby original is stored sequentially in the storage memory 8 and subject to memory transmission.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device and a communication method for accumulating and transmitting information of a document such as a facsimile device.

[0002]

2. Description of the Related Art When a facsimile machine temporarily stores image information in a memory and transmits it, if the memory capacity runs out during storage, the information accumulated up to that point will be cleared and the memory operation will be interrupted. There was a problem. In order to solve such a problem, the memory remaining coefficient is determined based on various reading conditions such as reading size, resolution, and binary / halftone before the transmitted original is stored in the memory, and the image information is stored in the memory. When it is possible to determine whether or not the image information cannot be stored in the memory, the document that cannot be stored in the memory is switched to a transmission mode that does not use the memory storage in advance (Japanese Patent Laid-Open No. 3-3565).

[0003]

However, if the original of the page after the memory overflow detection is directly transmitted without using the memory as described above, it is transmitted to a plurality of destinations by one operation. However, there is a problem that the operation which is an advantage of the memory transmission such as resending when a transmission error occurs cannot be performed.

The present invention has been made in order to solve such a problem, and it is an object of the present invention to obtain a communication device and a communication method capable of continuously transmitting data to a memory even when a part of a read document is not stored in the memory. It is intended.

[0005]

A communication device according to the present invention has a storage memory, a storage determination means, and a transmission control means, the storage memory stores information of a document to be transmitted, and the storage determination means is a transmission document. Is confirmed whether the next page of the next page can be stored in the storage memory, and when the next page of the transmission original cannot be stored in the storage memory, the transmission control means puts the originals of the next page and the following pages into the memory storage standby state. And

[0006] The transmission control means accumulates the stored transmission originals in the memory when the transmission of the information accumulated in the accumulation memory is started and the remaining memory amount becomes equal to or more than the remaining memory amount. When there is other document information already stored in the memory, it is preferable to store the transmission document that has been waiting after transmitting the other information in the memory.

Also, the communication method according to the present invention confirms whether the next page of the transmission original can be stored in the storage memory, and when the next page of the transmission original cannot be stored in the storage memory, the next page and subsequent pages are transmitted. The document is put in the memory storage standby state, and when the transmission of the information stored in the storage memory is started and the remaining memory amount exceeds the storable amount, the transmission document that has been on standby is stored in the memory. To do.

[0008]

According to the present invention, when the storage determination means determines that the next page of the transmission original cannot be stored in the storage memory while the information of the original to be transmitted is stored in the storage memory, the transmission control means determines the previous page. Put the remaining originals in the memory standby state without interrupting the memory procedure.

When the remaining information is already transmitted and the remaining amount of the memory becomes sufficient, the originals that have been waiting are sequentially accumulated in the accumulation memory and transmitted to the memory.

If there is transmission data in the storage memory other than the current file number, that data is transmitted and the standby transmission original is stored in the empty storage memory.

1 is a block diagram showing an embodiment of the present invention. As shown in the figure, the facsimile apparatus includes a system control unit 1 that manages the entire apparatus, a ROM 2 that stores a control program, a RAM 3 that stores information necessary for system control, and a communication control unit 4 that performs various control related to communication. Connected to the plotter 5 for recording the received image, the scanner 6 for reading the image, the operation display unit 7, the storage memory 8, the storage determination unit 9, the modem 10 for modulating / demodulating the transmission / reception data, and the line. It has a network control unit 11.

The storage memory 8 stores the read document information and the sent information. The accumulation determination unit 9 confirms whether the information of the document to be transmitted can be accumulated in the accumulation memory 8. If the communication control unit 4 determines in the accumulation determination unit 9 that the next page of the transmitted document cannot be accumulated in the accumulation memory 8, the remaining document is kept in the memory standby state and is accumulated in the accumulation memory 8 without interrupting the memory transmission procedure up to that point. The transmitted information is transmitted, and when the transmission is started and the remaining memory capacity of the storage memory 8 becomes equal to or larger than the storable amount, the transmission original document on standby is accumulated.

The operation of the facsimile apparatus configured as described above will be described with reference to the flowchart of FIG.

When performing memory storage / transmission, first, a plurality of originals to be transmitted are set on the scanner 6, and memory storage / transmission is selected (steps S1 and S2). When the memory accumulation transmission is selected, the accumulation determination unit 9 confirms the remaining capacity of the accumulation memory 8 at that time (step S3). If the storage memory 8 has a capacity for storing one or more pages of the original to be transmitted, the fact is sent to the communication control unit 4. When the communication control unit 4 receives a signal that the storage memory 8 has a storage capacity, it sets the transmission file number of the document (step S4),
The information of the document to be transmitted is stored page by page in a predetermined file in the storage memory 8 (step S5). Every time one page of the original document to be transmitted is stored in the storage memory 8, the communication control unit 4 confirms whether the original document to be transmitted has a next page (step S
7) If there is a next page, the fact is sent to the accumulation determination unit 9, and the accumulation determination unit 9 confirms the remaining capacity of the accumulation memory 8 at that time (step S8). As a result of this confirmation, if the storage memory 8 has a remaining capacity, the communication controller 4 repeats the above-described processing to store all the originals to be transmitted, and then input a plurality of destinations to be transmitted (step S9). Memory transmission is performed to each destination, and the transmission process ends (step S1).
0).

If the remaining capacity of the files stored in the storage memory 8 is insufficient while the originals to be transmitted are stored page by page (step S8), the communication control unit 4 interrupts the memory storage, The reading of the information of the remaining document is put in a standby state, and the fact is displayed on the operation display unit 7 to notify the operator (step S11).

After that, the accumulation judgment unit 9 confirms whether or not there is a file in which information of other originals is accumulated in the accumulation memory 8, and sends the confirmed result to the communication control unit 4 (step S1).
2). When there are no other files in the storage memory 8, the communication control unit 4 displays a display on the operation display unit 7 indicating that transmission to a plurality of destinations is impossible (step S13). When a single destination transmitted by the operator is input by this display (step S14), the information stored in the storage memory 8 is transmitted to the memory (step S15). Then, each time the storage memory 8 has a free space for one page, the information of the remaining originals on standby is sequentially stored in the storage memory 8 and transmitted to the memory (steps S16 to S19, S15). The information of all the originals to be transmitted is stored in the storage memory 8, and when the transmission is completed, the process ends (step S16).

Further, after the accumulation judging unit 9 puts the reading of the information of the remaining original document on standby and then confirms that there is a file in which the information of the other original document is accumulated in the accumulation memory 8 (step S12), another The usage amount of the file in which the information of the document is stored is confirmed, and the usage amount is displayed on the operation display unit 7 (step S20). After this message was displayed, the operation
Enter the number of originals in standby mode (step S2
1) The communication control unit 4 confirms whether or not the information of the original document in the standby state can be accumulated in the file in which the information of the other original document is accumulated (step S22). When it is determined that all the information of the original document in the standby state can be stored, the file in which the information of the other original document is stored is transmitted (step S23). All are stored in the storage memory 8 (steps S24, S2
5), memory transmission to a plurality of destinations to be transmitted (steps S9 and S10).

Further, when the communication control unit 4 cannot store all the information of the original document in the standby state in the file in which the information of the other original document is stored, the operation display unit 7 displays a message that it cannot be transmitted to a plurality of destinations. It is displayed (step S26). Then, all the files in which the information of other originals is stored are transmitted (steps S27, S28), and when a single destination to be transmitted by the operator is input (step S14), the destination memory is transmitted to the storage memory 8. Whenever an empty space is available, the information of the original document in the standby state is sequentially accumulated and transmitted, and when all the original documents have been transmitted, the process ends (steps S15 to S1).
9).

Further, when the originals to be transmitted are set and the memory transmission is selected and the remaining capacity of the storage memory 8 is not equal to or more than one page (steps S1 to S3), all the originals are set by the communication control unit 4. The memory accumulation of (step S2
9) Then, after transmitting the file of another original document stored in the storage memory 8 (steps S30 and S31), the file number of the original document on standby is set in the same manner as described above to perform the memory storage (step S4). , S5).

[0020]

As described above, according to the present invention, when it is determined that the next page of the transmission original cannot be stored in the storage memory while the information of the transmission original is stored in the storage memory,
Put the remaining originals in the memory standby state without interrupting the memory procedure up to that point, transmit the information that has already been stored, and sequentially store the originals that were waiting when the remaining memory became sufficient. Since it is configured to send to the memory in advance, even if it is not possible to store all of the documents to be sent at one time,
Memory transmission can be performed without switching to direct transmission.

If transmission data exists in the storage memory other than the information of the original to be transmitted, the transmission original can be stored in the empty storage memory by transmitting the data, It is possible to make effective use of the memory and reliably transmit to the memory.
