Description

  This invention receives subscriber number information from a partner terminal connected to the line based on the input of the calling number, and whether or not the subscriber number information is connected to the partner terminal corresponding to the calling number from this subscriber number information. It is related with the communication terminal device which detects.

  2. Description of the Related Art Conventionally, some facsimile apparatuses have a confidential function that allows transmitted image data to be extracted from a partner terminal only by a specific recipient, such as a communication terminal apparatus described in Patent Document 1. This is a password sent to the recipient terminal by sending a subaddress and password, storing the image data in the memory box of the recipient terminal specified by this subaddress, and the password entered by the recipient at the recipient side. The image data is extracted from the memory box when it matches.

Further, Patent Document 2 discloses a facsimile apparatus that makes it easy to input a subaddress and a password by allowing a subaddress and a password to be input together with an identification symbol following a calling number.

  By the way, the calling terminal is connected to the partner terminal through an external line by a telephone company exchange. In this exchange, there is a small possibility that the calling side terminal is erroneously connected to a destination terminal different from the calling number for some reason. In such a case, the image data is transmitted to a terminal different from the counterpart terminal corresponding to the calling number.

  In order to prevent erroneous connection due to such communication problems, communication terminal devices having a so-called “password transmission function” are well known. In this password transmission function, the calling terminal collates, for example, the last 4 digits of the calling number with the last 4 digits of the subscriber number information (SubID: Subscriber Identification) sent from the destination terminal connected to the line. Then, from this collation result, it is detected whether or not the counterpart terminal is a communication terminal corresponding to the calling number. Fax transmission is executed when the lower 4 digits of the SubID match the lower 4 digits of the calling number, and the fax transmission is stopped when they do not match. This password transmission function is possible because an external line number is registered as a normal SubID in each communication terminal.

  However, in a large organization such as a company, a system is adopted in which a plurality of communication terminal devices are connected via an extension switch, and fax communication is performed only within the company using the extension number set in each communication terminal device. Yes. Each communication terminal device is also connected to a telephone company exchange via an extension switch, and can perform fax communication with an external communication terminal device using an external line number.

  In such a communication terminal apparatus, an extension number may be set as the SubID. This is because the SubID of the calling side terminal is recorded on the recording paper as TTI (Transmitter Terminal Identification) information, for example, in the received document printed at the destination terminal, so that the destination side can easily identify the calling side. . In this case, when a password is transmitted from a communication terminal outside the company to a communication terminal within the company, an extension number is sent as a SubID to the calling terminal. As a result, in the outside calling party terminal, it is determined that the counterpart terminal is not a communication terminal corresponding to the calling number, and fax transmission is stopped. Therefore, it is impossible to transmit a password from a communication terminal outside the company to a communication terminal in which no external line number is set as the SubID. On the other hand, contrary to the above, password transmission could not be performed from an in-house communication terminal to a communication terminal having an external line number set as SubID.

  An object of the present invention is to provide a communication terminal apparatus that can more reliably determine a connection to a correct counterpart communication terminal corresponding to a calling number.

  In order to achieve the above object, according to the first aspect of the present invention, subscriber number information is received from a destination terminal connected to the line based on an input of a calling number, and the calling number is received from the subscriber number information. In the communication terminal device that detects whether or not the communication terminal device is connected to the other party terminal corresponding to the verification number, the verification result between the verification number and the subscriber number information input with a delimiter before or after the calling number And a collating means for detecting whether or not a connection to the counterpart terminal is made.

  According to a second aspect of the present invention, in the first aspect of the present invention, the verification unit is configured to verify the verification result between the verification-specific number and subscriber number information, and the verification between the calling number and subscriber number information. From the result, it is detected whether or not a connection to the counterpart terminal is made.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the verification means includes the verification-specific number input with a separator after the calling number, and the subscriber It is characterized in that it is detected from the collation result with the number information whether or not a connection to the counterpart terminal has been made.

  According to this invention, it is possible to more reliably determine the connection to the communication partner terminal corresponding to the calling number. That is, in the destination terminal, as the subscriber number information, an extension number (or external number), a branch number, a postal code, or the like is set instead of the external number (or extension number) that is the calling number. There may be. Here, in the present invention, an extension number (or an outside line number) that may be set as subscriber number information in the destination terminal as a dedicated number for matching with the subscriber number information of the destination terminal, A branch number or zip code can be set. Then, it is determined whether or not the partner terminal is a correct communication terminal corresponding to the calling number by comparing the reference number with the subscriber number information.

  Further, the collating means determines whether or not the connection to the destination terminal has been made from the collation result of the collation dedicated number and the subscriber number information and the collation result of the calling number and the subscriber number information. It is preferable to detect. That is, in the other party terminal, as the subscriber number information, an outside line number (or extension number) that is the calling number or a number other than the calling number may be set. Here, in the present invention, at the time of calling, a number other than the calling number of the counterpart terminal is set as the reference number. Then, it is determined whether or not the destination terminal is a correct communication terminal corresponding to the calling number by comparing the reference number with the subscriber number information and the matching between the calling number and the subscriber number information. The Accordingly, it is possible to more reliably determine the connection to the communication partner terminal corresponding to the calling number.

  Hereinafter, an embodiment in which a communication terminal device according to the present invention is embodied in a multifunction device will be described with reference to FIGS. This multifunction machine has a copy function, a scanner function, and a facsimile function.

  A reading unit 14 constituted by a flatbed scanner or the like reads an image of a document placed on the platen glass of the flatbed scanner and outputs black and white binary image data. The recording unit 15 including an electrophotographic printer records an image received by fax or an image of a document read by the reading unit 14 in a copy mode on a sheet drawn from one of a plurality of sheet cassettes.

  The operation unit 16 operated by an operator includes a mode key (not shown) for switching between a copy mode, a scanner mode, and a fax mode, and a start button (not shown) for starting a copy operation, a scanner operation, or a fax transmission operation. ) And a numeric keypad (not shown) for inputting numbers such as telephone numbers. Further, the operation unit 16 is provided with alphabet keys a to z and keys such as a semicolon, a colon, a parenthesis, a space, “&”, “+”, “−”, and a slash. The operation unit 16 is provided with a touch panel display that displays function keys for performing various settings for each mode. The display unit 17 including the touch panel display performs various displays such as the operation state of the multifunction machine 10.

  The image memory 18 temporarily stores image data received by fax or image data read from a document by the reading unit 14 in the fax mode. The image memory 18 temporarily stores image data read from the document by the reading unit 14 in the copy mode or the scanner mode.

  The codec 19 performs compression encoding and decoding of image data for fax transmission / reception and the like. The modem 20 modulates transmission data and demodulates reception data based on a fax transmission control procedure. The network control device 21 has a function of controlling connection with a public telephone line, a function of transmitting a dial signal corresponding to the telephone number of the other party, and a function of detecting an incoming call. The LAN interface 24 controls communication with a plurality of user terminals (not shown) connected via a local area network based on a TCP / IP communication protocol or the like.

  Next, a fax transmission process executed by the MPU 11 based on a program stored in the ROM 12 will be described. This fax transmission process is executed during facsimile transmission.

  As shown in FIG. 1, in the fax transmission process, first, in step (hereinafter abbreviated as S) 100, whether or not the calling number has been input by the user's numeric keypad input or the user's abbreviated number input. Is determined.

  When the calling number is input by the user in S100, next, in S101, a slash “/” as a delimiter is input by the user's slash key operation following the calling number, and the user also operates the numeric keypad. It is determined whether or not a verification-specific number has been input. This verification-specific number is input when a password is transmitted to the counterpart terminal.

  In this password transmission, first, for example, the lower 4 digits of the subscriber number information (SubID; Subscriber Identification) received from the line-connected partner terminal and the lower 4 digits of the calling number are collated. Next, when the last 4 digits of this subscriber number information matches the last 4 digits of the calling number, it is determined that the destination terminal is a communication terminal corresponding to the calling number, and fax transmission processing is continued. To do. On the other hand, when the last 4 digits of the subscriber number information do not match the last 4 digits of the calling number, it is determined that the partner terminal is not a communication terminal corresponding to the calling number, and the fax transmission process is stopped.

  The collation dedicated number is a number that may be set as subscriber number information in the counterpart terminal. That is, when the destination terminal is a communication terminal in the company, for example, an extension number may be set as the subscriber number information, and when the destination terminal is a communication terminal in the bank For example, a bank branch number may be set as the subscriber number information. Further, when the destination terminal is a post office communication terminal, for example, a postal code may be set as the subscriber number information.

  For example, when a password is transmitted from a communication terminal outside the company to a certain communication terminal in the company, as shown in FIG. 5 (a), verification is performed by separating the outside line number that is the calling number for the communication terminal with a slash. The extension number of the destination terminal as a dedicated number is input by the user. When a password is transmitted to another communication terminal in the company from another in-house communication terminal via an extension, as shown in FIG. 5 (b), the extension number that is the calling number for that partner communication terminal After that, an external line number of the communication partner terminal as a reference-only number separated by a slash is input by the user. When a password is transmitted from a communication terminal in another branch to a communication terminal in a bank branch, as shown in FIG. 5 (c), after the outside line number that is the calling number for that partner communication terminal. The branch number of the counterpart bank is input by the user as a reference-only number separated by slashes. Alternatively, when sending a password from a communication terminal of another post office to a communication terminal of a certain post office, as shown in FIG. 5 (d), after the outside line number that is the calling number for the destination communication terminal, The postal code of the destination post office as a collation-only number separated by a slash is input by the user. Then, when the verification number is entered together with the slash after the calling number by the user, the mode of facsimile transmission processing is switched from the normal transmission mode to the password transmission mode. In this password transmission mode, the above-described fax transmission processing by password transmission is performed.

  If it is determined in S101 that the user has entered a verification-specific number, it is next determined in S102 whether or not the user has pressed the start button. When the start button is pressed in S102, the calling number is sent to the line in S103.

  Next, in S104, it is determined whether or not a connection has been made to the counterpart terminal, for example, based on whether or not a called station identification number (CED) has been received from the counterpart terminal. If it is determined in S104 that the terminal is connected to the partner terminal, then in S105, a calling tone (CNG) is transmitted to the line.

  Next, in S106, it is determined whether or not a non-standard function signal (NSF) is sent from the counterpart terminal. If it is determined in S106 that the non-standard function signal has been sent, then in S107, the number of digits of the subscriber number information included in the non-standard function signal and the number of digits of the calling number are selected. The number of the lower digits of the subscriber number information corresponding to the small number of digits is compared with the number of the lower digits of the calling number. For example, when a 4-digit extension number is set as subscriber number information, it is determined whether or not the last 4 digits of the subscriber number information match the last 4 digits of the calling number.

  When the last 4 digits of the subscriber number information match the last 4 digits of the calling number in S107, it is determined that the destination terminal connected to the line is a communication terminal corresponding to the calling number. Next, in S108, data transmission is executed by a normal facsimile communication procedure. When the data transmission is completed in S108, the facsimile transmission process is terminated by a normal facsimile communication procedure.

  On the other hand, if the last 4 digits of the subscriber number information and the last 4 digits of the calling number do not match in S107, then in S109, the last 4 digits of the subscriber number information and the above-mentioned collation only It is determined whether or not the last four digits of the number match. When the last 4 digits of the subscriber number information match the last 4 digits of the dedicated verification number in S109, it is determined that the partner terminal connected to the line is a communication terminal corresponding to the calling number, S108 is executed.

  On the other hand, if the last four digits of the subscriber number information and the last four digits of the dedicated verification number do not match in S109, the partner terminal connected to the line is not the correct communication terminal corresponding to the calling number. To be judged. In step S110, the facsimile transmission process is stopped by a predetermined facsimile communication procedure, and the line with the partner terminal is disconnected.

  If it is determined in S101 that the collation dedicated number has not been input, the normal transmission mode is set, and then in S111, it is determined whether or not the start button has been pressed. If it is determined in S111 that the start button has been pressed, then the calling number is sent to the line in S112. Next, it is determined whether or not it is connected to the partner terminal in S113, and if it is determined that it is connected to the partner terminal, then in S114, normal data transmission is executed, and then this fax transmission process is performed. Is terminated.

  As described above, in the MFP 10 of this embodiment, for example, the last four digits of the subscriber number information received from the destination terminal connected to the line based on the input of the calling number by the user, and the calling number The lower 4 digits and the lower 4 digits of the verification dedicated number are sequentially verified. When the last four digits of the subscriber number information match the last four digits of the calling number or the verification-dedicated number, it is determined that the destination terminal is a correct communication terminal corresponding to the calling number, and fax transmission is performed. Executed. For this reason, for example, when trying to send a fax by sending a password from a communication terminal outside the company to a communication terminal in the partner company, either the external number or the extension number is used as the subscriber number information in the partner terminal. Even if the number is set, it can be determined whether or not the connection to the correct counterpart terminal corresponding to the calling number has been made. Therefore, when the password is transmitted, even though the partner terminal connected to the line based on the input of the calling number is the correct communication terminal corresponding to the calling number, the partner communication terminal is set to the calling number. It is prevented that it is determined that it is not a corresponding communication terminal. As a result, it is possible to more reliably determine the connection to the correct counterpart communication terminal corresponding to the calling number, and to more reliably perform fax transmission to the correct counterpart terminal.

In this embodiment, a slash “/” is used as a delimiter. However, the present invention is not limited to this. For example, “&” or “+” may be used as a delimiter.
In addition, when sending a fax at the calling terminal, it is also possible to use a configuration in which the verification-specific number that is input by being separated by a separator before the calling number and the subscriber number information are verified.

  Moreover, it is good also as a structure which performs only collation with subscriber number information and a collation exclusive number.

The flowchart which shows the communication process which the communication terminal device of one Embodiment performs. The flowchart which similarly shows a communication process. The flowchart which similarly shows a communication process. The block diagram which shows the structure of a communication terminal device. (A)-(d) are the calling number and collation-only number as examples.
