The key 8 is also used to select a mode and a threshold used for encoding control.

FIG. 2 is an explanatory diagram showing an example of the format of an address data table for storing various data of one-touch dialing and speed dialing.

The data stored in this table is, for example, “adrs_d” generated by one-touch dial [01].
data_tbl [0] ". In addition, various data of the one-touch dial [01], for example, dial data of a destination (“0077-03-3758-2111” in this example), a communication mode, and the like are stored.

As shown in FIG. 2A, each data is stored in the RAM 3 shown in FIG. 1 in the form of an array of each data structure. One data structure has a structure as shown in FIG.

In FIG. 2B, "dial_mod"
In the area indicated by "e0", modes such as a communication start speed, a mode in an international line, ECM transmission / non-transmission, a group dial, and a facsimile communication network are set.

In the area indicated by "dial_mode1", communication modes such as confidential transmission, relay instruction transmission, polling reception, timer transmission, ITU-T extended transmission using a subaddress and a password, and G3 / G4 transmission are provided. Is set.

In the area indicated by "dial_data", data indicating the location where dial data is stored is stored. The dial data is all stored in an area called a dial loop, as shown in FIG. FIG. 3 is an explanatory diagram showing the structure of the dial loop. This dial pool is a data storage area provided in the RAM 3 shown in FIG.
As shown in FIG. 3A, the data structure is an array of data structures. The content of one structure has a structure as shown in FIG. In FIG. 3B, the first area shows the suffix of the array of the next dial pool. From the next area, data is stored one byte at a time.

A more specific storage example will be described with reference to FIGS. FIG. 4 is an explanatory diagram showing an example of the storage status of the address data table, and FIG. 5 is an explanatory diagram showing an example of the storage status of the dial data.

FIG. 4B is a diagram showing “adrs_” in FIG.
data_tbl [0]. " In this, “0” is written in “dial_data”. This is the "adrs_data_tbl"
This means that the dial data "[0]" is stored from the 0th position in the dial pool.

That is, in the first area of FIG. 5A, the subscript of the next dial pool array is stored, and from the next area, dial data is stored by 1 byte.
10 bytes are stored. Data is, for example, BC
Stored as D code. In the example of FIG.

It can be seen that [1] is the last data of the dial data of “adrs_data_tbl [0]”. "D
"ial_pool [0]" stores the end of data. This data is represented by "e".

Returning to FIG. 2, "hash" in the address data table is data indicating the sum of dial data stored in "dial_data".

In general, hash has been used as a method for converting a text having an arbitrary length into a small fixed length. This serves as a “fingerprint” of the text, and can be used as a guide for determining whether two pieces of text data are equal or not by comparing hash values.

That is, when the dial data and the dial data on the calling side are compared in the DM prevention function to be described later, the comparison process is conventionally performed for all the dial data. However, in the present invention, hash is used. Simplifies the comparison process. That is, the sum (hash) of the data as the comparison source is obtained, and the sum is compared with the sum of the dial data of the comparison destination (the dial data of the calling device), thereby comparing the sum with the dial data of the comparison source. It can be determined whether or not there is a possibility that the previous dial data is equal. The specific use of this hash will be described later in detail. In addition, this has
h is calculated and stored when registering dial data.

"Isdn_sub_adrs_data" stored in the address data table of FIG. 2 is a place where data used when the facsimile apparatus is connected to the ISDN line and data of the sub address for DCH is stored. Is stored. This data is also referred to as “dial_dat” described above.
Like "a", it is stored as a dial pool.

"Adrs_n" in the address data table
"ame" stores destination abbreviation data indicating the destination name in ASCII code. This data is stored in the form of an array.

In the address data table, "ccitt_
sub "includes ITU-TT. Data indicating the location where the data of the sub-address used in Recommendation 30 is stored. This data is also referred to as “dia
Like "l_data", it is stored as a dial pool.

In the address data table, "ccitt_
pwd "includes ITU-TT. Data indicating the location where the data of the password used in Recommendation 30 is stored is stored. This data is also referred to as “dia
Like "l_data", it is stored as a dial pool.

In the address data table, "start_
"time" stores data indicating the location where the calling time is stored. This data is also referred to as “d
Like "ial_data", it is stored as a dial pool.

Next, according to ITU-TT. The transmission terminal identification frame specified in 30 will be described.

FIG. 6 is an explanatory diagram showing a command signal sent from the transmitting terminal in a frame format. As shown in FIG. 6A, this command signal is transmitted to the non-standard function frame (N
SS), a transmitting terminal identification frame (TSI) and a digital identification frame (DCS). The transmitting terminal is configured to output the command signal when receiving the digital identification signal (DIS) from the receiving terminal.

FIG. 6B is an explanatory diagram showing the structure of the HDLC frame of the transmission terminal identification frame (TSI), and FIG. 6C shows the contents of facsimile information included in the transmission terminal identification frame. FIG. FIG.
As shown in (c), the facsimile information is composed of 20 digits consisting of 0 to 9 and a space.

FIG. 7 is a block diagram of the ITU-TT. 1 is a conceptual diagram of a facsimile transmission / reception protocol recommended in F.30.

In the figure, the receiving-side facsimile apparatus (receiving station) sends out a DIS signal when there is an incoming call. Upon receiving the DIS signal transmitted from the receiving station, the transmitting facsimile apparatus (transmitting station) transmits a TSI / DCS signal, and then transmits training. The receiving station
When the TSI / DCS signal is received normally, a response is made with the CFR signal and the mode shifts to the image receiving mode. The transmitting station is CFR
Is received, an image signal is transmitted.

In the DM prevention function, the receiving station performs TSI / DCS
After receiving the signal and the training, the reception operation is continued only when either the one-touch dial data or the abbreviated dial data registered in the device matches the TSI data. At this time, if it is checked whether the one-touch dial or the abbreviated dial matches the TSI data with respect to each one-touch dial or the abbreviated dial, the comparison process takes an extremely long time, and the transmitting station responds with CFR In the worst case, the communication operation cannot be terminated normally. Therefore, using the above-mentioned hash, it is checked whether or not all of the one-touch dial and the abbreviated dial match the data of the TSI. If they match, after receiving the training signal normally,
Send out FR signal. When the transmitting station receives the CFR signal, it sends out an image signal. When one page of image data ends and communication ends, the transmitting station sends out an EOP signal. The receiving station sends out an MCF signal when the image signal can be received normally. When the transmitting station receives this signal,
Send N signal.

FIG. 8 is a conceptual diagram of a protocol when the DM prevention function operates. In this case, if the transmitting station has a number other than the number registered with the receiving station, the receiving station sends a DCN to the transmitting station to interrupt the communication.
A signal is sent.

FIG. 9 is a flowchart showing a facsimile receiving procedure in a facsimile apparatus having a direct mail preventing function.

The facsimile apparatus transmits the TSI
When the signal is received, the data of 20 digits (FIG. 6) of the TSI signal is temporarily stored in a predetermined area in the DRAM 11 shown in FIG. Therefore, first, the hash of the TSI data is calculated (step S1). Then, it is determined whether or not the comparison with all the one-touch dial and speed dial data registered in the apparatus has been completed (step S2). If the comparison has not been completed, the one-touch dial or speed dial is stored. One piece of hash data is extracted from the “adrs_data_tbl” that has been set, and compared with the hash calculated in step S1 (step S3), and it is determined whether or not both match (step S4). In this determination, if they match, the T
The dial data included in the SI signal and the h
"adrs_data_tb" in which ash is stored
The dial data is extracted from the dial pool indicated by "dial_data" of "1", and it is determined whether or not they match (step S5). In the determination of step S5,
If the dial data matches each other, facsimile reception is permitted.

If the hash does not match in step S4 or if the dial data does not match in step S5, the process returns to step S2.
It is determined whether the comparison between the dial data of another registered one-touch dial or the abbreviated dial and the dial number of the transmitting station included in the TSI signal has been completed, and if not completed, steps S2 to S5 Is repeated. If it is determined in step S2 that the comparison between the dial data of all the registered one-touch dials and the abbreviated dials and the dial data included in the TSI signal is completed, the T
The dial number of the transmitting station included in the SI signal is not registered in the facsimile apparatus. Therefore, in order to prevent the reception of the direct mail, the facsimile reception is not permitted, and the procedure is terminated as it is.

The hash of the address data table shown in FIG. 2 and the hash of the TSI data calculated in step S1 of FIG. 9 are set in the apparatus for comparing a fixed number of digits in the DM prevention function. Calculated from the last digit of the data, depending on the value. This set value is data stored in the RAM 3 in FIG. 1 and can be arbitrarily changed by the operator. Each time this data is rewritten, the has data in the address data table of FIG.
h is recalculated.

As described above, according to the present embodiment, instead of directly comparing dial data, first, hash, which is the sum of dial data, is compared.
Since the dial data is compared only when the value of sh matches, all the dial data registered as one-touch dial or abbreviated dial need not be compared, and the DM prevention function operates. In this case, the comparison process can be simplified. The present invention may be applied to a communication system including a plurality of devices, or may be applied to a facsimile device including a single device.

Further, a storage medium storing a program code of software for realizing the functions of the above-described embodiments is supplied to a system or an apparatus, and a computer (or CPU, MPU) of the system or the apparatus is stored in the storage medium. Needless to say, the object of the present invention can be achieved by reading and executing the program code.

In this case, the program code itself read from the storage medium realizes the novel function of the present invention, and the storage medium storing the program code constitutes the present invention.
