Description

Description: TECHNICAL FIELD [0001] The present invention relates to a fax terminal device having a function of avoiding fax reception from a device other than a partner fax terminal agreed in advance.

(Prior Art) In recent years, as faxes have become widespread, nuisance calls called “mischievous faxes” and “wrong faxes” have occurred. The typical unsolicited calls in fax include (a) sending plain white or black text as postponement.

(B) Sending mysterious documents with meaningless or obscene content.

(C) Texts with contents unrelated to the recipient are repeatedly delivered due to an error in specifying the destination of an automatic transmission fax.

In all cases, the receiving terminal is invalidated and held, not only can not receive other fax calls, but also as a unique problem of fax, it will wastefully consume the receiving paper burdened by the recipient, It has become a social problem.

The following methods have been devised and put into practical use as measures for preventing such unwanted calls.

(A) A method of receiving a subsequent text only when a receiving terminal receives a predetermined password with a calling terminal at the time of receiving a call.

(B) A method in which a closed reception service is registered in advance on the communication network side between terminals transmitting and receiving texts, and calls from other terminals are rejected.

However, in the case of (a), the number of digits of the personal identification number is at most about four digits, and if the nuisance call originating side investigates the crush, it is easy to be deciphered, and the personal identification number string has no meaning by itself. Therefore, there is a disadvantage that the user of the personal identification number is easy to forget. Further, there is a disadvantage that even a general fax document which does not have a password but is not a nuisance call is rejected.

In the case of (b), it takes time and effort to register at least on the network side, and there is an inconvenience of having to pay an additional service usage fee.

On the other hand, for example, Japanese Unexamined Patent Publication No. 63-189045, it is possible to receive and record only originals with a predetermined special format at the beginning of the original, and reject incoming calls for other originals. Facsimile apparatus is disclosed, but this is always limited to the one in which the special format is described at the beginning of the manuscript, and since the format comparison is a simple consistency comparison, noise and the There is a weak defect in displacement, inclination, etc.

(Object of the Invention) An object of the present invention is to prevent the reception of a nuisance call in a fax by continuing to receive a document only when an information portion at an arbitrary position on a document agreed with the originating terminal in advance is detected at the time of reception. To stop.

(Structure of the Invention) (Differences between the features of the invention and the prior art) In order to achieve the above object, the present invention provides a method according to claim (1), wherein a specific agreement is set in advance with a document document transmitting terminal. The signature pattern, the relative position of the signature pattern on the document, and the range of possible signature positions are stored, and whether or not the signature pattern exists there is determined by the similarity between the two graphic patterns. The main feature is to perform or stop receiving the document.

Further, in claim (2), the received document document information is temporarily stored, and when the received document is determined to be annoying, a harassing signal is input and the unsolicited document is received until the next document reception. The image information temporarily stored and, on the other hand, the image information stored permanently at least until after the next document reception is sequentially compared with the image information being received, and the similarity between the two graphic patterns is determined, and the similarity is determined to be high. In this case, the main feature is to stop the operation of receiving the document.

According to claim (1), in addition to the special signature pattern, the relative position and range of the signature pattern on the document are to be stored, so that the signature pattern needs to be fixed to a leading portion on the document. Therefore, the degree of freedom of the original used on the transmitting side is increased. Further, since the presence or absence of the specific signature pattern is determined based on the similarity of the pattern, there is an advantage that it is resistant to noise, a slight displacement or inclination of the document, and also to a slight enlargement / reduction. In claim (2), it is not necessary to previously store the signature pattern and its position / range by using the received unwanted document as a kind of inverse specific signature pattern.

(Embodiment) FIG. 1 is a block diagram showing a configuration according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a line control circuit for controlling an incoming call response, data reception from a subscriber line, and termination of reception. Is a signature pattern storage circuit for storing a pattern, which is a signature information part (related to claim 1). The signature pattern storage circuit also serves as a permanent document storage circuit, and stores the contents of the nuisance call document in preparation for the next reception. Has an action (related to claim (2)).

Reference numeral 3 denotes a signature position storage circuit for storing the relative coordinate information of the signature information portion in the document (referred to in claim (1)). 4
Corresponds to a signature detecting means, and outputs the pattern of the signature pattern storage circuit (permanent document storage circuit) 2 and the image data from the line control circuit 1 as a similarity of the signature portion by image signal processing such as a dynamic pattern matching method. 5 is a printing circuit that prints the received data, 6 is an alert circuit that notifies the called party that the received data was a malicious call, 7 is the received document, and 8 is the received document. A document display device 9 for displaying the received document document, and a temporary storage circuit 9 (related to claim 2) for holding the received document document until the reception of the document document is completed.
It corresponds to a temporary document storage circuit. Reference numeral 10 denotes a pointing device having two functions (related to the claim (2)). One of the functions is to specify a portion to be used as a signature from a text received in advance from a partner and its location in a document document 7. Another function is to designate the document while viewing the document display device 8, and to instruct the user to save the text received up to that point when the unwanted call is received. Numeral 11 denotes an image analysis processing circuit which, by the instruction of the indicating device 10, retrieves a part to be signed and its location from the temporary storage circuit 9 and registers it in the sign storage means 2 and 3, and a function for receiving a nuisance call. And a function of controlling the received text information to be stored from the temporary storage circuit 9 into a few signature storage means. Also, FIG.
3 illustrates the contents of information stored in the signature pattern storage circuit 2 and the signature position storage circuit 3 and the relationship between the two information.

That is, a pattern 1 for characterizing a document as information stored in the signature pattern storage circuit 2 shows an imprint, a pattern 2 shows a logotype, a pattern 3 shows a document name, and a pattern 4
Must have at least one
Alternatively, a plurality of sets are stored.

Further, the sign position storage circuit 3 stores dotted lines 1, 2, 3 in the logical position and range of each sign pattern in a document.
Are stored as shown in FIG.

Next, the operation will be described. When a document starts to be received via the line control circuit 1, the contents are sequentially sent to the temporary storage circuit 9 and the pattern matching circuit 4. The pattern matching circuit 4 uses the information stored in the signature pattern storage circuit (permanent document storage circuit) 2 and the signature position storage circuit 3,
It is monitored whether or not a signature pattern (FIG. 2) exists in the designated portion of the received content.

And if there is a signature pattern in the specified part,
The contents temporarily stored in the temporary storage circuit 9 are printed by the printing circuit 5 and delivered as a document 7 to the recipient. If the signature pattern does not exist in the designated portion, the alert circuit 6 reports that the call is a nuisance call, and also designates the line control circuit 1 to immediately stop the reception. The line control circuit 1 requests the network side to end communication based on this instruction, and terminates the call.

When the document starts to be received in the above, the received content is displayed on the document display device 8. The receiver monitors the text and, if the call is a nuisance call, presses the storage key 10a of the pointing device 10, and the contents stored in the temporary storage device 9 up to that point are a signature pattern storage circuit (permanent document storage circuit). 2 is stored. Then, when the document starts to be received from the second time onward, the contents are transferred to the pattern matching circuit 4.
First, the signature pattern storage circuit (permanent document storage circuit)
2 are successively compared with each other, and if they match, an alert circuit 6 reports that the call is a nuisance call, and instructs the line control circuit 1 to immediately stop the reception. The line control circuit requests the network side to end communication according to this instruction, and terminates the call.

In this way, according to the present invention, the malicious call is determined by collating the signature pattern or displaying the document, so that the recipient can immediately take measures to end the communication.

The signature pattern shown in FIG. 2 is desirably one that characterizes a document, such as an imprint, logotype, or signature. Further, since these existence positions are not always at exactly the same relative position every time a document is received, the sign position storage circuit 3 sets a range where the sign pattern can exist.

Also, a plurality of types of signature patterns to be stored in the signature pattern storage circuit (permanent document storage circuit) 2 are allowed for one position / range portion stored in the signature position storage circuit 3. Also, a plurality of stored position / range information may be allowed to overlap each other.

By these measures, the degree of freedom in creating a document on the side that sends a non-nuisance call can be increased, and the document can be transmitted as in the conventional document transmission.

(Effects of the Invention) As described above, the present invention is applicable only when an information portion on a document agreed with the calling terminal is detected at the time of reception.
By continuing to receive documents and automatically avoiding calls that have the same text as the document that was previously determined to be a malicious call, it is possible to minimize the reception of unwanted calls in faxes and to suspend the terminal from invalidation. In addition to being able to suppress unnecessary consumption of paper and receiving paper, the following advantages are provided.

(A) There is no need to use a password that is easy to decipher or forget.

(B) There is no need to register on the network or use additional services.

(C) By receiving some nuisance calls, the received document part can be left as evidence, which is advantageous in elucidating the originator or disputing.

(D) The range in which the signature information part is allowed to be allowed and the complexity of the signature information part itself can be easily changed, and as a result, the hardness of the guard against unwanted calls can be freely set. Therefore, the possibility of rejecting a general fax document that is not a nuisance call can be almost eliminated.

(E) The pattern matching allows some tolerance by judging the similarity, and is strong against noise, document displacement, inclination, enlargement / reduction.
