The image signal sent via U1 is demodulated by the modem 2, decoded by the control unit 3 into image data, and the image is recorded by the recording unit 4 according to this data.

The configuration of the parts described above is the same as the conventional one. In the present embodiment, a DTMF detection circuit 7 is provided between the NCU 1 and the control unit 3 in addition to the above configuration. The DTMF detection circuit 7 is a confidential destination sent by a DTMF signal from a DTMF (dual-tone multi-frequency code) push-button telephone attached to the other party's transmitter when receiving confidential communication to be described later. The code of the personal identification number that indicates a specific user is detected.

In addition to the well-known ROM (read-on memory) 8 storing a control program, the RAM (random access memory) 9 used for temporary storage of various data, etc. A large capacity non-volatile memory 10 for storing the received image data is provided.

Further, in the present embodiment, when a confidential communication is received, a known portable wireless device is used to call a specific user who is the confidential destination designated by the code of the personal identification number received in the DTMF signal to the device. The calling transmitter 11 is connected.

Further, in the present embodiment, each of the plurality of portable wireless receivers 12A to 12Z shown in FIG. 2 which receives the radio wave transmitted from the portable wireless device calling transmitter 11 and generates an alarm sound for calling is facsimile. It shall be given to each of multiple users of the device.

Then, in the present embodiment, based on the above-mentioned configuration, the secret number of the confidential communication by the above-mentioned DTMF signal is detected prior to the normal pre-procedure at the time of reception, and when the secret number is detected, the image received after that The data is stored in the non-volatile memory 10 without being output. At the same time, the portable radio receiver calling transmitter 11 transmits a radio wave having a frequency for ringing the portable radio receiver attached to the specific user, which is designated by the personal identification number, to call the specific user. Then, the called user inputs the personal identification number with the keyboard of the operation unit 6, and if the personal identification number matches the previously received and detected personal identification number, the received image data in the non-volatile memory 10 is recorded and output.

Next, details of the operation during such confidential communication will be described with reference to FIGS. 3 and 4. Note that FIG. 3 is an explanatory diagram of a confidential communication procedure with the apparatus of this embodiment as the receiving side, and FIG. 4 is a flow chart of the control procedure at the time of reception by the control unit 3 in FIG. Set to mode.

Also, both the transmitting side device and the receiving side device are group G3 devices according to CCITT (International Telegraph and Telephone Consultative Committee) recommendation T30,
The telephone attached to the transmitting device is a DTMF push-button telephone.

As shown in FIG. 3, the transmitting side first sets the transmission original and then sends a calling signal to the receiving side by dialing the telephone.

When the ringing signal arrives at the receiving side, the line L is connected to the telephone T.
Is switched to the facsimile machine side, and the control unit 3 starts the control shown in FIG.

First, in step S1 of FIG. 4, the operator on the calling side sends a code of a personal identification number for instructing a specific user who is a destination of confidential communication to the receiving side by a push button of an attached DTMF telephone within a fixed time. Send out a prompting sound. For this signal sound, select a frequency that is not mistaken for a CED (Called Station Identification) signal that notifies the operator of the sender of the response of the receiver that is sent first in the following procedure. Further, instead of the signal sound, a voice message explained to the transmitting side operator may be transmitted.

In response to this, when the operator on the transmitting side intends to perform confidential communication, he / she operates the push button of the telephone to transmit the personal identification number as shown in FIG.

On the other hand, on the receiving side, the control unit 3 detects the personal identification number by the DTMF detection circuit 7 for the above-mentioned fixed time in step S2 following step S1 in FIG. 4, and then in step S3, whether or not the personal identification number is detected. If it is not detected, the following normal reception operation is performed, and if it is detected, the PIN code is
Store in RAM9 or the like and proceed to step S4.

In step S4, a known pre-communication procedure is performed. That is, as shown in FIG. 3, first, the above-mentioned CED signal is sent to the transmitting side, and then the NSF (non-standard device) signal, the CSI (callee identification) signal,
Send the DIS (digital identification) signal etc. to inform the transmitting side of the function of the receiving side device.

In response to this, the transmitting device receives NSS (non-standard device setting) signal, TSI (transmitting station identification) signal and DCS (digital command).
Send a signal to the receiving side, instruct the receiving side which mode you want to communicate with, then send a training signal and TCF (training check) signal to make the receiving side prepare to receive the image data of the message, and prepare Wait for completion.

When the reception side is ready for reception, the reception side notifies the transmission side by a CFR (reception preparation confirmation) signal.

In response to this, the transmission side transmits the image data of the message after the training signal.

The receiving side transmits the image data, but as shown in step S5 of FIG. 4, the control unit 3 receives the image and does not record and output the received image data unlike the normal reception. Stored in the non-volatile memory 10.

Then, as shown in FIG. 3, when the end of the image data is known by transmitting the EOM (end of message) signal on the transmission side, the control unit on the reception side performs a known post-procedure in step S6 in FIG. That is, as shown in FIG. 3, when the image data of the message is normally received, the MCF (message confirmation) signal is sent to notify the calling side, and the DCN (disconnect command sent from the calling side in response to this is sent. ) Receiving the signal, the line L is switched to the telephone set T side to end the communication.

Then, in step S7 of FIG. 4, the control unit 3 on the receiving side drives the portable wireless device calling transmitter 11 by referring to the personal identification number data previously stored in the RAM 9, and the user who instructs the personal identification number. A radio wave for ringing any one of the portable radio receivers 12A to 12Z attached to is transmitted, and the corresponding portable radio receiver is ringed to notify the user that a confidential image has been received, call.

Next, in step S8, the user called by the ringing waits for input of the personal identification number using the ten-key pad of the keyboard of the operation unit 6 or the like.

When the input of the personal identification number is completed, the process proceeds to step S9, it is checked whether or not the personal identification number input in step S8 matches the personal identification number previously received and stored in the RAM 9, and if not, the process returns to step S8, If they match, the process proceeds to step S10, the image data previously stored in the nonvolatile memory 10 is recorded and output, and the control ends.

As described above, according to the present embodiment, the user who is the destination of the confidential communication is called by the ringing of the portable wireless receiver, so that it is surely notified that the confidential communication addressed to himself / herself has been received. By inputting his / her own personal identification number, the user can see the received image addressed to him / herself without seeing it by a third party. If the user keeps his / her secret code secret, the third party cannot output the received image data in the non-volatile memory 10.

Further, the operator on the transmission side does not need to contact the user who is the recipient of the confidential information on the reception side, and even if the user is not near the reception side device at the time of communication, the transmission image is sent to the third party on the reception side. Can be sent without being seen by.

Further, it goes without saying that the above-mentioned configuration related to confidential communication can be applied to communication devices other than the facsimile device.

[Effect] As is apparent from the above description, according to the communication device of the present invention, when the call signal is received, a voice signal prompting the operator on the calling side to send a push button signal indicating a specific destination is transmitted. Sending means for sending, a detecting means for detecting a push button signal from the calling side, and a storing means for storing an image received from the calling side when the push button signal is detected within a predetermined time by the detecting means. A calling means for calling the portable wireless device when the received image is stored in the storage means and an output means for outputting the received image stored in the storage means in response to a user inputting a predetermined personal identification number are provided. Since the configuration is adopted, the user can know that the image is received even if he / she is not near the receiving side device at the time of receiving the image, and further, at a proper time, the user can output the received image from the storage means. You can Therefore, the received image can be obtained without bothering the people around.

When the call signal is received, a voice signal prompting the operator on the calling side to send a push button signal designating a specific destination is sent. It is possible to know that the device on the receiving side has the function to call, there is no need to confirm beforehand whether or not the device has the function, and the destination can be immediately instructed as necessary. The excellent effect that instructions can be given by a simple push button operation is obtained.
