SOLUTION: In the case a FAX, at the time of receiving the data from the other line L1-LN while recording received image data, the received image data are tentatively stored in an image storage part 8, and at the point of time of ending printing output by a recording part 6, the stored image data are taken out and printed and outputted from the recording part 6. Also, when the first communication request specifying the area of the image storage part 8 is present from one of the lines L1-LN and the second communication request specifying the same area of the image storage part is present from the other line L1-LN while storing it in the specified area, it is not stored and communication is ended.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a communication terminal apparatus accommodating a plurality of lines which connects a plurality of lines and enables simultaneous communication on each line.

[0002]

2. Description of the Related Art Conventionally, a communication terminal device having a function of connecting a plurality of lines has been widely used. In addition to a telephone network, a facsimile communication network (F-net), an ISDN, or the like is connected to a communication terminal device. Simultaneous communication with the other party is enabled. For example, if a facsimile apparatus is connected to two lines, the facsimile transmission is performed from one of the lines while the facsimile transmission is being performed on one of the lines by utilizing the memory transmission or memory reception function. In a line, facsimile reception or facsimile transmission can be performed simultaneously in parallel. At the start of communication, one of the predetermined lines is in use (during communication)
In this case, communication can be performed through another unused (empty) line.

[0003]

However, in the conventional communication terminal device accommodating a plurality of lines, when confidential reception or the like in which the same memory box number is designated is performed simultaneously through different lines, writing to the memory or the like is not performed. There have been problems such as conflicts and separate data being mixed in the memory box.

[0004] That is, in the case of confidential communication, the transmitting side:
Transmission starts after specifying the memory box number,
If the specified number matches the number specified by another transmitting side, the same memory box is to be used. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a communication terminal apparatus accommodating a plurality of lines in which both data are not mixed even when the same memory area is designated simultaneously through a plurality of lines. And

[0005]

To achieve the above object, a communication terminal accommodating a plurality of lines according to a first aspect of the present invention includes a data storage unit having a plurality of areas, and stores data from any of the lines. There is a first communication request in which the area of the copy is specified, and while storing the first communication data in the specified area,
The second area where the same area of the data storage unit is specified from another line
When the communication request is issued, the second communication data is not stored in the designated area.

Here, the plurality of areas of the data storage section include memory boxes for confidential reception, and the data storage area is determined by the designation from the transmission side. When a communication request in which an area is specified is received, communication data is stored in the specified area. However, if the same area is already in use, communication data is not stored. According to a second aspect, in the first aspect, while the first communication data is being stored in the designated area,
When a second communication request in which another area of the data storage unit in which communication data is not being stored is specified from another line, the second communication data is stored in the other specified area. I do.

According to a third aspect, in the first aspect, when the first communication data is stored in the designated area and a second communication request in which the same area of the data storage section is designated from another line, The second communication data is temporarily stored in another area, and is stored in a designated area when the processing of the first communication data is completed. Here, the other area may be another area of the data storage unit or a unit for storing other data. Also, when the processing of the first communication data is completed, it means that the reception is confidential reception.
It means that the personal identification number is input, the stored data is read out, and the printout of this data is completed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a configuration of a communication terminal apparatus accommodating a plurality of lines according to the present invention. Here, the configuration of the facsimile machine F is shown as an example, but the present invention is not limited to this, as long as a plurality of lines can be connected, such as a personal computer having a data communication function. Is also good.

In FIG. 1, reference numeral 1 denotes a CPU and the like.
The main control unit that controls the following units includes a plurality of lines L1,
A line control unit accommodating connection functions of L2,..., LN, an operation unit 3 including various operation keys and switches, a display unit 4 including a liquid crystal screen and LEDs, and a document table (non- A reading unit for reading image data of a document set in the drawing), a recording unit 6 for printing out image data on a recording paper prepared in advance, a ROM and a RAM 7 as a system memory, and a data storage 8 according to the present invention. And an image storage unit that stores encoded image data for communication or the like.

The line control unit 2 includes each of the lines L1 to L
For N, there are provided an NCU (network control device) for transmitting dial numbers and the like, and modems 21 to 2N for modulating and demodulating signals for performing facsimile communication. Further, the main control unit 1 includes processing circuits for facsimile communication control, encoding / decoding of image data, and the like. The facsimile apparatus F encodes image data read by the reading unit 5 and transmits the encoded image data through any of the lines L1 to LN, and decodes the image data received through any of the lines L1 to LN. Is printed out from the recording unit 6 to enable simultaneous communication in each of the lines L1 to LN.

In the case where data is received from other lines L1 to LN while the received image data is being recorded, the image data received later is temporarily stored in the image storage unit 8 and then stored in the recording unit. At the time when the printing output by the printing unit 6 is completed, the stored image data is taken out and printed out from the recording unit 6. The facsimile apparatus F performs such a basic operation, but one of a plurality of memory boxes (areas) provided in the image storage unit 8 is specified through each of the lines L1 to LN, and the image is stored in the specified memory box. It has a confidential reception function that can store data. The confidentially received image data is read out and recorded by the recording unit 6 only when a predetermined personal identification number is input to each memory box by the operation unit 3.

In the present invention, from a plurality of lines L1 to LN,
It proposes a case where a confidential reception request is made by specifying the same memory box. There is a confidential reception request in which a certain memory box is designated from one of the lines L1 to LN, and while the received data according to the request is being stored in the designated memory box, the other lines L1 to LN
Therefore, when there is a confidential reception request in which the same memory box is designated, data received by a confidential reception request that is given later is not stored in this memory box.

That is, there is a first communication request in which the area of the image storage unit 8 is designated from any of the lines L1 to LN,
While the first communication data is being stored in the designated area, when a second communication request is received from another line L1 to LN in which the same area of the image storage unit 8 is designated, the second communication request is stored in the designated area. Do not store data. That is, if a communication request in which an area is specified is received, communication data is stored in the specified area. If the same area is already in use (data is being stored), the communication is terminated without storing the communication data. I do.

On the other hand, there is a confidential reception request in which a certain memory box is designated from any of the lines L1 to LN, and while the received data according to this request is stored in the designated memory box, another confidential reception request is issued. When there is a confidential reception request in which another memory box is designated from the lines L1 to LN of the above, if the other memory box is not storing data, the confidential reception request which has been stored in the other memory box later Stores the received data.

That is, there is a first communication request in which the area of the image storage unit 8 is designated from any of the lines L1 to LN,
While the first communication data is being stored in the designated area, if there is a second communication request from another line L1 to LN that designates another area of the image storage unit 8 where no communication data is being stored, The second communication data is stored in another specified area. In other words, when a communication request specifying a region is received, if the specified region is not in use, communication data is stored in the specified region even if another region is storing communication data.

FIG. 2 shows the above operation in a flowchart (steps 100 to 110). Here, a case is shown in which a memory management table is provided to manage the memory box of the image storage unit 8, and the memory management table stores the memory box number and the number of received pages (memory management table). Will be described later).
By providing this management table, the image storage unit 8
It is not necessary to divide each area in advance one-to-one according to the memory box number, and an empty area can be allocated to the memory box when a confidential reception request is made.

After receiving the call, if there is a confidential reception request during the handshake processing, the designated memory box number is detected, and this memory box number is searched from the memory management table (steps 100 to 103). As a result of the search, if the same memory box number is not stored,
Since the confidential reception specifying the same memory box number has not been performed through the other lines L1 to LN, the specified memory box number and the specified memory box number are stored in the memory management table.
Set the initial value (0) of the number of received pages. Then, the image data is received while incrementing (counting up) the number of received pages, and the received image data is sequentially stored in the designated memory box (step 1).
04-109).

On the other hand, as a result of searching the memory management table at the start of confidential reception, if the same memory box number has already been stored, confidential reception in which this memory box number is designated is performed through other lines L1 to LN. Because
Perform error processing (steps 104, 110, 10)
9). In this error processing, the same error as when an error occurs during data reception may be notified to the transmission side. If the transmitting side has a redial function, confidential reception can be performed normally when the designated memory box is empty at the time of the next incoming call by redial.

FIG. 3 is a diagram showing an example of the configuration of the memory management table. In the table shown in the figure, "type" is added in addition to "memory number (memory box number)" and "number of pages" as items, and in addition to confidential reception, it is also possible to perform management on behalf of memory reception and memory transmission. ing. The memory number is provided for each type, and the area storing the data can be identified by the type and the memory number.

Since the present invention is directed to a communication request specifying an area of the data storage unit, only "confidential reception" is a target among the types shown in FIG. The memory box number is searched from the memory numbers whose type is "confidential reception", and if there is a match, the received data is not stored in the memory box.
Perform error handling.

In the case of proxy reception or transmission, the main controller 1 searches for an empty memory and stores data in this empty memory every time the processing is started, so that both the type and the memory number are the same. If not, it is impossible. Next, another operation of the present invention will be described with reference to the flowcharts of FIGS.
12, 300 to 303).

In FIG. 4, the memory management table is searched at the start of confidential reception, and if the same memory box number has already been stored, confidential reception with the specified memory box number is performed through other lines L1 to LN. Therefore, another unused (empty) memory box is searched from the memory management table, and the received image data is stored in this memory box. If there is no unused memory box,
Perform error handling.

Then, as shown in FIG. 5, when the designated memory box becomes empty, the contents of the memory management table for this memory box are changed, and the data stored in another memory box is replaced with the designated memory box. Transfer to the box and at the same time rewrite the memory management table. That is, while the first communication data is being stored in the designated area, the second area in which the same area is designated from the other lines L1 to LN.
, The second communication data is temporarily stored in another area, and when the processing of the first communication data is completed, the second communication data stored in the other area is stored. Store in the specified area.

According to this, since the data of the communication request after the designation of the same area is temporarily stored in another area, no communication error occurs on the transmission side, and there is no need to retransmit the data. Is not wasted. Also, when the processing of the previous communication request is completed, the data stored in another area is automatically transferred to the specified area. An operation such as when receiving a confidential street may be performed.

Although another memory box is used as another area here, the present invention is not limited to this.
A RAM 7 or the like provided as a system memory may be used. Also, when the processing of the first communication data is completed, when the confidential reception is performed, the password is input, the stored data is read out, the printout is completed, and the memory box can be overwritten. This means that the corresponding location in the memory management table has become unused (empty).

The notification of the reception of the second communication data such as the fact that the confidential message has been received may be stored once in the above-mentioned other memory box, or may be transferred to a designated memory box after that. . Furthermore,
The communication request specifying the area of the data storage unit has been described by taking a confidential reception request as an example. However, the present invention is not limited to this. For example, a reception request for an image specifying a bulletin board box number or another communication terminal A communication request for receiving data from another communication terminal device and storing the data in a designated area in advance in order to perform search polling reception from the device is also included.

Further, a plurality of lines L1 to L1 are connected to one communication terminal device (facsimile device F) by the line control unit 2.
Although the configuration in which N is connected has been described, the configuration is not limited thereto.
One or a plurality of option boards having a communication function may be added to the communication terminal device body, and each may be connected in a daisy chain. According to this, data can be transferred between the communication terminal device main body and the option board via the dual port RAM provided in each option board, and communication of a plurality of lines can be realized.

[0028]

As can be understood from the above description, the communication terminal apparatus accommodating a plurality of lines according to the first to third aspects of the present invention has the first structure in which the area of the data storage unit is designated from one of the lines. While the first communication data is being stored in the designated area, and a second communication request in which the same area of the data storage unit is designated from another line, the second communication request is designated in the designated area. Since the communication data is not stored, even when the same memory area is specified at the same time through a plurality of lines, both data are not mixed.

That is, even when two or more confidential reception requests specifying the same memory box number are simultaneously made,
There is no contention for writing to the memory or a plurality of confidential reception data mixed in one memory box. In particular, according to the third aspect, the data of the communication request after the same area is designated is stored in another area, so that a communication error does not occur on the transmitting side and there is no need to retransmit. When the processing of the previous communication request is completed, the data stored in the other area is automatically transferred to the specified area. Therefore, the receiving side determines that the data is stored in the specified area. The data may be taken out by a conventional operation.
