Description

  The present invention relates to a communication terminal device such as a facsimile machine, a multifunction machine having multiple functions such as a facsimile function and a copying function.

  In general, in a communication terminal device such as a facsimile machine or a multi-function peripheral, a caller can be called by dialing the phone number of the other party directly by operating the numeric keypad, or by operating a one-touch key or an abbreviated key. There is a case where the telephone number of the destination is read and dialed.

In addition, when a telephone number is input from the telephone number input means so that only an appropriate destination can be dialed, it is determined whether or not this telephone number is registered in the telephone number registration means, and this telephone number registration is performed. In the means, a plurality of telephone numbers are registered for each operator's identification code, and only when the input identification code is registered, the telephone number corresponding to this identification code is searched and input. A facsimile apparatus is disclosed in which a dialed call is made to the other party of the telephone number when the telephone number is registered (see, for example, Patent Document 1).
JP-A-4-286269

  A user of a communication terminal device such as a facsimile device may want to prevent private use of the facsimile depending on circumstances. The simplest way to prevent private use is to prohibit any transmission. However, this makes normal use impossible and very inconvenient. In addition, as in the technique described in Patent Document 1, there is a method in which a dialable telephone number is registered in advance for each operator, and dialing is permitted when the registered telephone number is input. However, it is necessary to register a usable telephone number for each operator, and registration is troublesome. In addition, there is a problem that the telephone number of the other party may be registered without permission by the operator.

  This invention was made paying attention to the said problem, Comprising: It aims at providing the communication terminal device which can prevent private use except the other party which the user's manager aimed at more efficiently. It is said.

  This communication terminal apparatus is configured to directly dial In when a direct dial input is made by setting the one-touch key and / or abbreviated key, direct dial input means, direct dial prohibition mode setting means, and direct dial prohibition mode. And means for prohibiting.

  Further, in the communication terminal device of the present invention, means for applying operation protection to the one-touch / abbreviated dial, setting of the one-touch / abbreviated dial, and canceling the direct dial prohibition mode in the setting of the direct dial prohibition mode Passcode input means for inputting a protect passcode may be provided.

  According to the first aspect of the present invention, since the direct dial prohibition mode is set, only one-touch / abbreviated dialing is permitted, and direct dialing is prohibited. Use can be prevented with higher probability than in the past.

  According to the invention of claim 2, if the one-touch / abbreviated dial is protected in the setting of the direct dial prohibition mode and the protect passcode is not entered, the one-touch / abbreviation cannot be changed, and this direct dial prohibition is not allowed. Since the mode cannot be turned off, it is also possible to prevent an unnecessary destination from being registered in the one-touch / abbreviated dial table.

  Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a block diagram showing a configuration of a facsimile machine (multifunction machine) which is an embodiment of a communication terminal apparatus according to the present invention.

  In FIG. 1, a CPU (central processing unit) 1 as a main control unit has a function of comprehensively controlling each unit constituting the device.

  The CPU 1 includes an NCU (Network Control Unit) 2, MODEM 3, ROM 4, RAM 5, image memory 6, display unit 7, operation unit 8, image reading unit 9, image recording unit 10, CODEC (encoding / coding). Decoder: Coder and Decoder) 11 and LAN I / F 12 are connected via a bus 13.

  The NCU 2 is controlled by the CPU 1 to control connection with a telephone line network (PSTN) 14 that is a communication line. Further, the NCU 2 has a function of sending a dial pulse corresponding to a telephone number (including a FAX number) of a communication partner and a function of detecting an incoming call. MODEM3 is an ITU (International Telecommunication Union) -T recommendation T.264. 30, T.M. 4 according to the facsimile transmission control procedure (facsimile communication procedure) according to FIG. 17, V. 27ter, V.I. The transmission data is modulated and the received data is demodulated in accordance with 29. MODEM3 is a V. 8, V. V. using 34. It is also applicable to 34 FAX. Specifically, the MODEM 3 has a function of modulating transmission data, which is a digital signal, into an analog voice signal so as to be sent to the telephone line network 14 via the NCU 2. The MODEM 3 has a function of demodulating an analog voice signal received from the telephone line network 14 via the NCU 2 into a digital signal.

  The ROM 4 stores a program for controlling the operation of the entire apparatus. The RAM 5 stores data necessary for control by the CPU 1 and data that needs to be temporarily stored during the control operation. The RAM 5 has a one-touch table 5a and a shortening table 5b. The one-touch table 5a stores destination information such as a destination name, a destination telephone number, and a destination mail number corresponding to each key of the one-touch key. Similarly, destination information such as the destination number is registered in the shortening table 5b corresponding to the shortened number. The image memory 6 stores the image data read by the image reading unit 9 in a compressed state. Further, the image memory 6 stores image data received from an external device such as a personal computer via a network (LAN) 15 or image data read from a recording medium in a compressed state (JPEG or the like).

  The display unit 7 displays icons, key buttons, message contents necessary for data transmission / reception, a telephone number and a FAX number input by the operation of the operation unit 8, and the like. As the display unit 7, an LCD (Liquid Crystal Display) is used. As shown in FIG. 2, the operation unit 8 includes a numeric keypad 8a, a mode switching key 8b, a one-touch key 8c, an abbreviated key 8d, a registration key 8e, a start key 8f, a stop key 8g, and the like. The numeric keypad 8a is used for inputting a telephone number, a FAX number, and other numerical values. The mode key 8b is used to switch and set various operation modes. For example, the direct dial prohibition mode can be set by operating the mode switching key 8b and the registration key 8e. The one-touch key 8c is used to call a destination telephone number or FAX number with one touch. The abbreviated key 8d can be input with abbreviated dial by operating this key and a two-digit numeric key. The registration key 8e is used for other registration in order to perform one-touch abbreviated registration of the destination telephone number or FAX number. The start key 8f is used to instruct the start of facsimile communication or copy operation. The stop key 8g is operated to stop various processing operations.

  The image reading unit 9 optically scans and reads image data of a document when performing facsimile transmission or copying. The image reading unit 9 can also read a color image. In the case of color reading, the image reading unit 9 optically scans a document image and obtains RGB three-color separation signals. The image recording unit 10 includes an electrophotographic printer, and records received image data and image data of a document read by the image reading unit 9 in a copying operation on a recording sheet.

  The CODEC 11 encodes (encodes) the read image data according to the MH, MR, MMR method or the like to transmit or store the image data. Further, the CODEC 11 decodes (decodes) the image data received in the compression-coded state for recording by the image recording unit 10. The LAN I / F 12 is for exchanging data with an external device via a LAN (local area network) 15, and is connected to an external device such as a PC (personal computer) via the LAN I / F 12. . For example, image data to be copied can be received from an external device via the LAN I / F 12.

  Next, the processing operation at the time of dial input of the facsimile apparatus of this embodiment will be described with reference to the flowchart shown in FIG. When the job starts, it is determined in step ST1 whether or not there is a key input. If any key of the operation unit 8 is pressed, the determination is YES and the process proceeds to step ST2. In step ST2, it is determined whether or not the keypad. If the operated key of the operation unit 8 is the numeric keypad 8a, the process proceeds to step ST3. On the other hand, if the operation is a key other than the numeric keypad 8a, the process proceeds to step ST7. In step ST3, it is determined whether or not the direct dial prohibition mode is set. This determination is made based on whether or not the direct dialing prohibition mode is turned on (set) by operating the mode switching key 8b or the like of the operation unit 8. If the direct dialing prohibition mode is ON, the process proceeds to step ST4. On the other hand, if the direct dialing prohibition mode key remains OFF (is not set), the process proceeds to step ST5.

  In step ST4, a message “Direct dialing prohibited” is displayed on the display unit 7, and the process is terminated. In this case, even if the telephone number is directly input with the numeric keypad 8a, it is not taken in as valid. That is, dial In is not permitted.

  In step ST5, since the direct dialing prohibition mode is not set, the input numerical value is taken in as a dial number. Then, the process proceeds to step ST6. In step ST6, a call is made to the destination of the entered numeric telephone number. In step ST7, it is determined whether or not the operated key of the operation unit 8 is the one-touch key 8c. When the one touch key 8c is operated, the process proceeds to step ST8. On the other hand, if the one-touch key 8c is not operated, the process proceeds to step ST9. In step ST8, with reference to the one-touch table 5a, the telephone number corresponding to the operated one-touch key 8c is read and a call is made to the destination.

  In step ST9, it is determined whether or not the operated key of the operation unit 8 is the shortened key 8d. When the shortcut key 8d is operated, the process proceeds to step ST10. On the other hand, if the shortcut key 8d is not operated, the process proceeds to step ST11. In step ST10, with reference to the shortening table 5b, the telephone number corresponding to the operated shortening key 8d is read, and the destination is called. In step ST11, another process is executed according to the operated key.

  Next, in the direct dialing prohibition mode, a processing operation when canceling this mode or changing and registering one-touch / abbreviated registration contents will be described with reference to the flowchart shown in FIG. If this processing routine is entered, it is determined in step ST21 whether or not the direct dialing prohibition mode is cancelled. When the operator performs an operation to cancel the direct dialing prohibition mode by operating the key of the operation unit 8, that is, when the mode switching key 8b is operated, the direct dialing prohibition mode is displayed on the display unit 7 and the registration key 8e is operated. The process proceeds to step ST23. On the other hand, if the key operation for canceling the direct dial prohibition mode is not performed, the process proceeds to step ST22.

  In step ST22, it is determined whether or not the registration change is one touch / shortening. If the operator changes the registered contents of the one-touch table 5a or the shortened table 5b by operating the registration key 8e by operating the key of the operation unit 8 and by operating the one-touch key 8c or the shortened key 8b, the process proceeds to step ST23. . In step ST23, “Please enter your passcode” is displayed on the display unit 7. Next, the process proceeds to step ST24.

  In step ST24, it is determined whether or not a passcode has been input. When the operator inputs the pass code, the process proceeds to step ST25. In step ST25, it is determined whether or not the pass code input by the operator matches the pre-stored protect pass code. If they do not match, nothing is done, that is, the direct dialing prohibition mode is turned off or the one-touch / abbreviated registration change is not permitted, and the process is terminated. If a passcode match is obtained, the process proceeds to step ST26. In step ST26, the direct dial prohibition mode is turned off (cancelled) or the one-touch / abbreviated registration change is permitted.

  In the above embodiment, the direct dialing prohibition mode, the direct dialing prohibition mode cancellation, and the one-touch / abbreviated change are set using the mode switching key 8b and the registration key 8e. A single hard key with or a soft key may be used.
