DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system which is capable of arbitrarily selecting and setting a data storage mode for a specified memory box by assigning a sub-address to each of them, so that transmission / reception data and data read by reading means can be stored and saved. It relates to improvement of a terminal device.

[0002]

2. Description of the Related Art Conventionally, some facsimile apparatuses, which are one type of communication terminal apparatuses, have a memory box function. The memory box function is to store received image data in a memory box with a specified number, or to take out data from a memory box with a specified number and transmit it.

FIG. 5 is a diagram for explaining a communication procedure for realizing the memory box function. FIG. 5A shows the case where the data transmitted by the calling side is stored in the memory box of the called side, and FIG. 5B shows the case where the calling side receives the data stored in the memory box of the called side (polling). Receiving). In the case of transmitting data from the calling side in FIG. 5 (a), when the called side detects a CNG (calling tone) (1), it sends out a CED (called station identification signal) (2), followed by (2). , NSF (non-standard function signal), CSI
(Calling terminal identification signal), DIS (digital identification signal)
Is transmitted (3). Then, for these signals, P
WD (password (transmission) signal), SUB (sub address signal), TSI (transmission terminal identification signal), and DCS (digital command signal) are transmitted (4).

In the transmission and reception of the signals in (3) and (4), when the calling side detects the setting of the sub-address capability and the password capability from within the DIS, the calling side responds with a password (PWD) and a sub-address (SUB). ) To specify the called memory box. Here, the sub-address is data that is set in advance for each memory box on a one-to-one basis and is used to access (store, reference, and retrieve data) each memory box. This is data that is set in advance for each memory box and is used to restrict access to the memory box.

[0005] That is, although the memory box is designated by the sub-address, if the password transmitted at the same time does not match the preset password, access to the designated memory box is prohibited. Since a plurality of passwords can be set for one memory box, in such a setting, if any password is transmitted, access to the memory box is permitted. Further, since it is possible not to set a password, in such a setting, access to the memory box is permitted regardless of transmission without a password or transmission of any password.

Subsequently, upon receiving the TCF (training check signal) (5), the called side returns a CFR (reception preparation confirmation signal) (6) and receives the image data (PIX) (7). . The received data is stored in a memory box designated by the sub-address and accessed by the password. In this case, after receiving the image data, the MPS (multi-page signal) is received (8), the MCF (message confirmation signal) is returned (9), and the image data of the next page (second page) is received. (10).

When the EOP (procedure end signal) is received (11) and it is confirmed that all the image data has been received, the MCF is returned (12), and the DCN (disconnection command signal) is received (13). , End the communication. Thereafter, the called side can take out the image data from the memory box and print out this image on recording paper. On the other hand, in the case of the polling reception of the calling side in FIG.
When CNG is detected (21), CED is transmitted (2).
2) Then, NSF, CSI and DIS are transmitted (2)
3). Then, in response to these signals, PWD (password (polling) signal), SEP (selection polling signal), CIG (calling terminal identification signal), and DTC (digital transmission command signal) are transmitted (24).

In (23) and (24), when the calling side detects the setting with the sub-address capability and the password capability from within the DIS, it similarly sets both capabilities in the DTC, and performs polling reception. A password (PWD) and a selection polling signal (SEP) are transmitted to specify a memory box for access. continue,
The called party sends out DCS (25), TCF (26),
Upon receiving the CFR (27), the image data (PIX) is transmitted (28). This transmission data is specified by the selection polling signal and taken out from the memory box to which access is permitted by the password.

Here, after transmitting the image data, the MPS
Is transmitted (29), the MCF is returned (30), and the image data of the next page (second page) is transmitted (3).
1). When transmission of all image data is completed, EOP
Is transmitted (32), the MCF is received (33), the DCN is transmitted (34), and the communication is terminated.

[0010]

However, in the conventional communication terminal device having a memory box function, data received from another communication terminal device can be stored in the memory box, and data read from a document can be stored in the memory box. It has become. Therefore, the received data, not the read data, may be erroneously transmitted to another device.

In addition, since data is additionally registered in the memory box sequentially, there is a case where previously registered (stored) data unnecessary for the partner apparatus is transmitted. The present invention has been made in view of such circumstances, and has as its object to prevent erroneous data transmission by storing data in accordance with conditions set for each box.

[0012]

According to the present invention, which is proposed to achieve the above object, there are provided a storage means in which conditions for storing data in a memory box are set in advance, and a data reception specifying a memory box, or And control means for storing data in a memory box according to the conditions set in the storage means when data is read, wherein the memory box assigns and specifies a sub-address used in a facsimile communication procedure. The storage means stores, as conditions for storing data in the memory box, a combination of permission or prohibition of storage of received data and invalidity or validity of already stored data, and prohibits storage, Any storage mode can be selected from overwrite, file addition, and page addition. When receiving data or reading data, the stage refers to the storage mode selected and set by the storage means and performs necessary control processing on the memory box designated by the data. ing.

In such a communication terminal device with a memory box function of the present invention, for each memory box specified in advance by a subaddress used in a facsimile communication procedure (transmitted in the form of a signal in an actual communication procedure), Since it is possible to prohibit the storage of received data or to set invalid or valid data already stored, you can select and set any storage mode from storage prohibition, file overwrite, file addition, page addition, For example, a bulletin board function that uses a box as a bulletin board, a confidential function that allows only a person who has input a password to take out data in the box, and temporarily stores data in a box for relay transmission to another communication terminal device A relay function can be realized.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a communication terminal device with a memory box function according to the present invention. Here, the configuration of the facsimile apparatus F is shown as an example, but the present invention is not limited to this, and transmission and reception of data specifying a memory box from another communication terminal apparatus via the communication line L is performed. Any communication terminal device that enables the communication terminal device may be used. For example, a personal computer (personal computer) having a data communication function may be used.

In FIG. 1, reference numeral 1 denotes a main control unit which constitutes a control means of the present invention such as a CPU, 2 an NCU which performs network control such as transmission of a dial signal to a communication line L, and 3 which performs facsimile communication of image data. For modulating and demodulating signals, 4 has a plurality of memory boxes, and an image memory for storing image data of facsimile communication (hereinafter, referred to as “memory box 4”). RAM for storing management information of the LCD, 6 ROM for storing a processing program in advance, 7 LCD screen and LE
A display unit composed of D or the like; 8 an operation unit composed of various operation keys and switches; 9 a reading unit for reading image data of a set document; 10 a recording unit for printing out image data on recording paper Reference numeral 11 denotes an external recording medium reading unit for reading a processing program or the like from a recording medium fd such as a floppy disk.

The main control unit 1 includes processing circuits for facsimile communication control, image data encoding / decoding, and the like. Further, the main control unit 1 includes an external recording medium reading unit 1.
According to the instruction of the processing program read from step 1, the following operation is executed. This facsimile machine F
Performs the basic operation of encoding the image data read by the reading unit 9 and transmitting the encoded image data through the communication line L, decoding the image data received through the communication line L, and printing out the image data from the recording unit 10. When the memory box 4 is designated by another communication terminal device (such as a facsimile machine or a personal computer) through L, the received image data is stored in the designated box 4 or the data of the designated box 4 is stored. It has a transmission function (memory box function).

In this case, in order to specify the memory box 4, the calling side performs SUB in a pre-procedure of facsimile communication.
(Sub address signal) and PWD (Password signal) are transmitted, and the called side determines permission / prohibition of access to the memory box 4 based on these (see FIG. 5). Note that the memory box function includes all functions that enable transmission and reception of data using the memory box 4,
For example, a bulletin board function that uses the memory box 4 as a bulletin board, a confidential function that permits only a person who has input a personal identification number to retrieve data in the box 4, and data stored in the box 4 for relay transmission to another communication terminal device And a relay function for temporarily storing the information.

In the present invention, the conditions for storing data in the memory box 4 are previously set in the RAM 5 by operating the operation unit 8 or the like. When receiving (including polling reception) or reading data from the reading unit 9,
Data is stored in the memory box 4 according to the conditions set in the RAM 5.

The "read data" described below
Includes data read from the recording medium fd when the communication terminal device is a personal computer, data created on a screen, and the like. The conditions for storing data in the memory box 4 that are stored as management information in the RAM 5 include, specifically, permission or prohibition of storing received data and invalidity or validity of already stored data. .

That is, the memory box 4 is transmitted from another device.
When reception of the data is designated, when the storage permission of the reception data is set, the reception data is stored in the memory box 4. On the other hand, when the prohibition of the storage of the reception data is set, other data is stored. Without storing the data received from the device in the memory box 4, immediately disconnecting the line,
The received data is only printed out by the recording unit 10.

As a result, the data stored in the memory box 4 is only the data read from the reading unit 9, so that it is possible to prevent data received from another device from being transmitted to another device. That is, the memory box 4 in which the storage of the received data is set to be prohibited can be set as a dedicated box for transmission (including polling transmission), and the memory box 4 in which the storage of the received data is set to be stored is set to Can be set in the Allow box.

When data specifying the memory box 4 is received from another device, or when data is read by the reading unit 9 after specifying the memory box 4, the validity of the stored data becomes invalid. Is set to add to the data in Box 4,
While the data is stored in the memory box 4, if the already stored data is set to be invalid, the data in the box 4 is deleted or overwritten so that the data is stored in the memory box 4. .

FIG. 2 (a) shows the inhibition of storage of received data /
FIG. 2B is a flowchart showing an operation at the time of reception after setting such permission.
Here, a case where the memory box 4 is used as a bulletin board box is shown. The setting of the bulletin board box is sequentially performed by the operation of the operation unit 8, the box name, the box 4
After registering the sub address and password corresponding to,
Set reception prohibition or reception permission. In this case, when reception is permitted, it is further set whether to overwrite and store the received original data (100 to 103).

When such a setting is set as the management information of the bulletin board box, when the data is received thereafter, the management information is referred to, and if the reception permission is set, the data is received according to the overwrite / addition setting. While the data is stored in the specified memory box 4, if the reception inhibition is set, the line is immediately disconnected (110-1).
15).

Next, FIG. 3 shows an example of an operation when data read from the reading unit 9 is stored in the specified memory box 4. Here, a case (200) is shown in which the storage method is selected by operating the operation unit 8 before reading the document data, instead of setting in the RAM 5 in advance. Here, if the overwrite is selected, if there is already stored original data, this is deleted, and then
The data is stored (200 to 204).

On the other hand, if the addition is selected, the data is stored in the memory box 4 in accordance with the selection of the file addition or the page addition. When adding a file, the main control unit 1 automatically designates an empty file number and additionally accumulates data, and when adding a page, the operation unit 8 operates the operation unit 8 to specify a file to be added. , Data is additionally stored so as to start from the page next to the last page of the specified file (204 to 2).
07).

That is, when the validity of the already stored data is set as a condition for storing the data in the memory box 4, one of the already stored data is selected, and It is possible to store linked data. FIG. 4 schematically shows a state of storing data in the memory box 4.
(A) shows a state in which a file (No. 1, No. 2, No. 3) of data received or read is always overwritten on BOXa, and (b) is a file always added to BOXb (file addition). It shows how to do. (C) shows a state in which file No. 1 (pages 1 to 3) is selected and pages are added (4 pages are added) in a state where files No. 1 and No. 2 are stored in BOXc.

When storing the data to be polled and received as a page addition, a target file may be selected during the polling reception operation in the same manner as when the read data is stored. When storing the transmitted data as a page addition, the calling side may specify a file together with the memory box 4 in a signal of a pre-procedure before data communication.

As shown in (a), if the data stored in the memory box 4 can be overwritten, the memory can be used effectively and only the latest data (file) can be stored at all times. Therefore, it is possible to prevent old data from being transmitted to the partner device. (C)
As shown in (1), since pages of data stored in the memory box 4 can be added, two files (or three or more files when additional pages are added) can be transmitted or printed out as the same file. Therefore,
Manuscript data can be easily managed.

[0032]

As can be understood from the above description, according to the communication terminal device with a memory box function of the present invention, when data reception and data reading with the memory box specified are performed, the memory box is read in advance. The data is processed according to the storage mode set in. For example, when storage is set to be prohibited, storage of received data is prohibited in the memory box, and only read data is stored. Therefore, data received from another device is Can be prevented from being transmitted.

When file overwriting is set, data in the box can be overwritten so that only the latest data can be stored at all times. Can be prevented.

Further, when the setting is to add a file, the data received without erasing the old data is stored as new data, and when the setting is to add a page, the data is already stored. Since a page is added to the data and the data can be saved as one file, the saved data can be transmitted as a series of data or printed out.
