If the transmitting side desires confidential transmission, a pre-transmission procedure is performed. In, a signal SUB for designating confidential transmission is transmitted, and the F-code registered in the confidential box of the confidential destination is designated as the FIF of the signal SUB. Here, the format of the F code, the method of use, and the like are determined by the Telecommunications Industry Association, and therefore, detailed description is omitted.

[0004] Thereby, the center device stores the received image information in the confidential box in which the F code specified by the signal SUB is registered. Then, the user of the confidential destination designates the confidential document retrieval to the center device, designates the confidential box to be retrieved by inputting the F code, and inputs the password to record and output the confidential document.

[0005] In addition, polling reception specifying a confidential box is also possible. In this case, the facsimile apparatus requesting polling reception transmits a signal SEP for designating selective polling reception during the pre-transmission procedure, and also specifies a confidential box requesting polling reception in the FIF of the signal SEP. Set the F code to perform. Also, a signal PWD carrying a password for authentication.
Is also transmitted to the center device.

[0006] Thereby, the center apparatus transmits the received signal PWD to the confidential box of the designated F code.
When the authentication is successful, the image information stored in the confidential box is transmitted to the polling reception request source.

[0007] The storage of image information in the confidential box can also be performed using a scanner of the center device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
An embodiment of the present invention will be described in detail.

FIG. 1 shows a configuration example of a group 3 facsimile apparatus according to an embodiment of the present invention.

In FIG. 1, a system control unit 1 performs various control processes such as a control process of each unit of the group 3 facsimile apparatus and a facsimile transmission control procedure process. A system memory 2 includes a system control unit. 1 stores a control processing program to be executed, various data necessary for executing the processing program, and the like, and constitutes a work area of the system control unit 1. A parameter memory 3 is provided in the group 3 facsimile apparatus. The clock circuit 4 is for storing various kinds of unique information (for example, registration information of the one-touch dial function), and outputs the current time information.

The scanner 5 is for reading a document image at a predetermined resolution, the plotter 6 is for recording and outputting an image at a predetermined resolution, and the operation display unit 7 is a group 3 facsimile. It is used for operating the device, and includes various operation keys and various display devices.

The encoding / decoding unit 8 encodes and compresses the image signal and decodes the encoded and compressed image information into the original image signal.
This is for storing a large number of image information in a coded and compressed state to realize the above-mentioned confidential box function.

The group 3 facsimile modem 10 is for realizing a group 3 facsimile modem function, and is a low-speed modem function (V.21 modem) for exchanging transmission procedure signals and mainly exchanging image information. High-speed modem function (V.17 modem,
V. 34 modem, V.34. 29 modem, V.29. 27ter modem etc.).

The network controller 11 is for connecting the group 3 facsimile apparatus to a public network (PSTN) and has an automatic transmission / reception function.

The system control unit 1, system memory 2, parameter memory 3, clock circuit 4, scanner 5, plotter 6, operation display unit 7, encoding / decoding unit 8, image storage device 9, group 3 facsimile modem The network controller 10 and the network controller 11 are connected to an internal bus 12, and data exchange between these elements is mainly performed through the internal bus 12.

Data exchange between the network controller 11 and the group 3 facsimile modem 10 is directly performed.

The group 3 facsimile apparatus is provided with a plurality of boxes by using the image storage device 9, and each box is shown in FIG. 2 in order to manage each box. The box information as shown is created and stored in the system memory 2.
The actual image information is stored in the image storage device 9 and storage management information (not shown) for managing the stored image information.
In addition, information specifying which box the image information belongs to is added, and the storage of the image information in each box is managed.

The box information includes box type information indicating the registered F code, password, box name, and the type of the box (“confidential box”, “bulletin board”, “relay box”, etc.) Of distribution destination information.

A predetermined number of the box information is prepared in advance, and whether or not the box is used by a user operation is registered. Such an operation for using a box is referred to as "opening a box".

Each element of the box information is
Contents are registered as needed. So, for example,
There may be a confidential box where the password is not registered.

Now, according to ITU-T Recommendation T. According to 30,
When the F code is designated using the signal SUB, information for authentication can be transmitted using the signal SID.

Usually, only one signal SID is used because it is used only for authentication. However, in this embodiment, a plurality of signal SIDs can be transmitted as shown in FIG. Then, the information frame of the first signal SID (FI
Information for authentication is set in F), and arbitrary function code information is set in the second and subsequent signals SID.

Here, the function code information is formed by connecting the "function identifier" and the "function code". For example, the value of “function identifier” is “# *”, and the function code is “004”.
If "5", the content of the function code information is "# * 004".
5 ".

The data length of the FIF of the signal SID is
Since the data type is 20 octets, and the data type is a number from 0 to 9, *, #, and space, the function code information can take values within the limits of the data length and data type.

Further, a plurality of function code information can be included in the FIF of the signal SID. For example, in the case of the format described above, one function code has six digits, so that up to three pieces of function code information can be included.
Further, when more function code information is included, it can be dealt with, for example, by reducing the number of digits of the function code to three digits or reducing the length of the function identifier to one digit. In order to suppress the recognition error of the function code information, it is conceivable to lengthen the length of the function identifier.

The FIFs of the second and subsequent signals SID can include, in addition to the function code information, arbitrary data information applied by the function code information. In this case, a format in which “function code information” and “data information” are linked can be applied, for example, “# * 02”.
3 # ** 0462277777 ". here,"#
“* 023” is the function code information, which is “# **”
And a function code of “023”. “# ** 0462277777” is data information, and a data identifier of “# **” and “046”
2237777 ".

In the above example, the case where the signal SUB is used has been described. However, in the case of polling reception, the signal PWD applied for authentication can be handled in the same manner as the signal SID described above. .

FIG. 4 shows an example of the transmission procedure in that case.

In this case as well, the signal PWD sets information for authentication in the information frame (FIF) of the first signal PWD, and sets arbitrary function code information in the second and subsequent signals PWD. I do.

In this case, the same content as the signal SID described above can be applied to the content of the signal PWD.
