Abstract

PURPOSE:To prevent picture information from sending to an erroneous facsimile terminal by collating a telephone number notified from the communication destination terminal with the called telephone number when the communication destination facsimile terminal has a telephone number notifying function, and stopping the communication when they do not correspond. CONSTITUTION:Whether the communication destination facsimile terminal has the telephone number notifying function or not is stored into a compacted dial memory 10. When the facsimile terminal, whose possession of the telephone number notifying function is stored, is called, the called telephone number is collated with the telephone number notified from the communication destination facsimile terminal by a CSI presence/absence discriminating means 3a, when they do not correspond, a communication stop processing means 3b stops the communication. Thus, sending the picture information to the erroneous party can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile device having a function of confirming a called destination facsimile terminal.

(Prior Art) Conventionally, facsimile apparatuses do not have means for confirming the connected facsimile terminal at the time of making a call, and image information is sent out unconditionally.

By the way, when a call is made, a facsimile terminal different from the facsimile terminal that originally made the call may be connected due to factors such as external noise being mixed into the dial signal. However, as mentioned above, conventional facsimile machines do not have a means to confirm the other party's facsimile terminal.
There was a problem in that image information was sent to the wrong facsimile terminal.

(Problems to be Solved by the Invention) As mentioned above, conventional facsimile machines do not have a means to confirm the connected facsimile terminal at the time of making a call, and if a facsimile terminal different from the facsimile terminal that made the call is connected. There was a problem in that when this was done, the image information was sent to the wrong person.

The present invention has been made in consideration of such circumstances, and its purpose is to confirm whether or not the facsimile terminal connected at the time of making a call is the facsimile terminal that made the call. An object of the present invention is to provide a facsimile device which can prevent image information from being sent to an incorrect facsimile terminal.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a determination means for determining whether or not a communication partner facsimile terminal has a telephone number notification function, and a telephone number determined by the determination means. and storage means for storing the presence or absence of a notification function in association with the telephone number of the corresponding facsimile terminal, and when a call is made to a facsimile terminal stored in the storage means as having a telephone number notification function, This system is characterized in that the calling telephone number is compared with the telephone number notified from the communication partner's facsimile terminal, and if they do not match, the communication is stopped.

(Function) By taking such measures, if the facsimile terminal of the communication destination has a telephone number notification function, the telephone number notified from the communication destination facsimile terminal can be compared with the telephone number of the originator. , if they do not match, communication is stopped, so if an incorrect facsimile terminal is connected, communication can be stopped.

(Embodiment) A facsimile apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the facsimile machine. In the figure, reference numeral 1 denotes a reading scanning section which reads image information of a set transmission original (not shown) and provides an image signal obtained by this reading to an encoding section 2. The encoding unit 2 encodes the input image signal and converts it into image data. The image data obtained here is introduced into the transmitting/receiving section 4 via the control section 3, modulated by the modulation/demodulation circuit 4a, and sent out from the network control circuit 4b to the line 5.

On the other hand, image data arriving via the line 5 is received and demodulated by the transmitting/receiving section 4 and input to the decoding section 6 via the main control section 3. The decoding unit 6 decodes the input image data and reproduces the image signal. The reproduced image signal is input to the recording scanning section 7, and outputted as an image onto recording paper by the recording scanning section 7.

In the figure, 8 is a telephone, and 9 is an operation panel consisting of an input section 9a and a display section 9b.

The facsimile device also includes a speed dial memory 10 that stores phone numbers registered in one-touch dialing and speed dialing, and information indicating whether the facsimile terminal of this phone number has a phone number notification function. are doing.

By the way, the control unit 3 has, for example, a microcomputer as a main control circuit, and in addition to control means for transmitting/receiving and reading and recording, it also has a CSI presence/absence determination means 3a.
and communication stop processing means 3b. Here, CS
The I presence/absence determining means 3a determines whether or not a C3I signal is sent from the connected facsimile terminal after the line is connected at the time of making a call, so that the connected facsimile terminal has a telephone number notification function. This function serves as a discriminating means for determining whether or not it has. Further, when a call is made to a telephone number registered in the speed dial memory 10, the communication stop processing means 3b is configured to receive a call from the facsimile terminal notified by a CSI signal from the connected facsimile terminal after the line is connected. It functions as a control means that compares the telephone number with the calling telephone number and stops communication if they do not match.

Next, the operation of the facsimile machine configured as described above will be explained according to the processing procedure of the control section 3. First, as shown in FIG. 2, the control section 3 monitors the occurrence of outgoing and incoming calls in steps a and b. here,
When the occurrence of an incoming call is detected in step a, the control section 3 performs a well-known general incoming call process in step C.

On the other hand, when the occurrence of a call is detected in step b,
Next, in step d, the control section 3 causes the network control circuit 4b to send out a dial signal corresponding to the input speed dial number, the telephone number corresponding to the pressed one-touch button, or the directly input telephone number, etc. Performs the well-known call processing.

Then, in step e, the control unit 3 determines whether the telephone number called in step d is stored in the speed dial memory 10.

Here, if the called telephone number is registered in the speed dial memory 10, the control unit 3, in step f, sends information indicating the presence or absence of the telephone number notification function registered in the speed dial memory 10 together with the telephone number. Check to determine whether the called destination facsimile terminal has a telephone number notification function.

Here, if the called destination facsimile device has a telephone number notification function, the control unit 3 in step g
The presence/absence determining means 3a is used to determine whether or not the C12 signal is received, and if the C8I signal is received, then in step h, a call is made to the telephone number of the facsimile terminal of the communication partner notified by the C3I signal. Match with phone number. As a result of this verification, if the telephone number notified by the CSI signal and the calling telephone number match, then the calling facsimile terminal has been correctly connected.
In step 1, the control section 3 performs well-known communication processing such as sending image data or polling processing.

Note that if the C8I signal is not received in step g, or if the telephone number notified by the C8I signal and the calling telephone number do not match in step h, the connected facsimile terminal will change to the facsimile terminal from which the call was originally made. Therefore, in step j, the control section 3 uses the communication stop processing means 3b to stop communication and perform communication error processing such as issuing a warning to the operator. Therefore, if the wrong facsimile terminal is connected, no image data will be sent.

On the other hand, if the called destination facsimile device is registered as having no telephone number notification function in step f, the called destination facsimile terminal did not have a telephone number notification function in the previous communication, or the called destination facsimile device Since this is the first time a call has been made to the terminal, the control unit 3 determines whether the called destination facsimile terminal has a telephone number notification function based on whether or not the C8I signal is received in step k. Here, when the C8I signal is received, since the called destination facsimile terminal has a telephone number notification function, the control unit 3 in step 1 combines the telephone number notified by the C8I signal and the calling telephone number. If they match, the calling facsimile terminal is correctly connected, and the called terminal has a telephone number notification function, so the control unit 3 makes the call in step m. After registering in the speed dial memory 10 that the destination facsimile terminal has a telephone number notification function, the process moves to step i and performs well-known general communication processing.

Further, if the C12 signal is not received in step k, or if the telephone number notified by the C8I signal and the calling telephone number do not match in step l, the process directly proceeds to step i.

Incidentally, in step e, if the calling telephone number is not registered in the speed dial memory 10, the control section 3 directly proceeds to step i and performs a well-known general communication process.

According to this embodiment, if the called facsimile device has a phone number notification function, from the second communication onwards, the phone number notified from the connected facsimile terminal and the calling phone number Since the image data will not be sent unless the notified phone number matches the calling phone number, noise etc. may be mixed into the dialing signal when making a call, resulting in a different facsimile than the one that was called. Even if a terminal is connected, image data will not be sent to the wrong facsimile terminal.

Note that the present invention is not limited to the above embodiments.

For example, information indicating the presence or absence of a telephone number notification means is not limited to telephone numbers registered with one-touch dialing or speed dialing. In addition, various modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] According to the present invention, whether or not the communication partner facsimile terminal has a telephone number notification function is stored and a call is made to the facsimile terminal stored as having the telephone number notification function. When a call is made, the calling phone number is compared with the phone number notified by the other party's facsimile terminal, and if they do not match, the communication is stopped. If this occurs, communication will be stopped. This prevents image information from being sent to the wrong party.
