A preferred embodiment of the present invention will be described in detail with reference to FIG. 2, which shows a flowchart of a method for storing call request information according to a preferred embodiment of the present invention applicable to such a facsimile apparatus. First, the fax machine automatically receives a message when a message is received from a calling party, and automatically connects a telephone line for a telephone call when the user hooks up for a telephone call (FAX / TEL MODE). Is set to). In the fax / tel mode as described above, the central processing unit 10 proceeds to step 100 to search for a predetermined number of times the ring sent by the exchange is requested by the calling party. At this time, the central processing unit 10 proceeds to step 104 if the ring has been a predetermined number of times, otherwise proceeds to step 102 to perform the operation. In step 104, the central processing unit 10 controls the network controller 18 to connect the telephone line. When the telephone line is connected, the central processing unit 10 reads the data according to the guidance message stored in the memory unit 12, synthesizes the voice signal through the voice synthesizing unit 14, and then synthesizes the network control unit 18. Send to the calling party through Here, the above information message "Hello? Press the START button to send a message, press" * "and then the telephone number to make a call. Press the" # "when the telephone number is completed." Can be After the sending of the guide message, the central processing unit 10 proceeds to step 108 to generate a pseudo so that the user of the facsimile device knows that a call has arrived. During the generation of the pseudo ring, the central processing unit 10 proceeds to step 110 where a CNG tone generated when a caller inputs a start button to transmit a message is received from a telephone line. Search for if possible. At this time, if the CNG tone is received, the central processing unit 10 proceeds to step 112 and performs automatic message reception, otherwise proceeds to step 114. In step 114, the CPU 10 searches whether the user is hooked off to make a telephone call. At this time, if the user hooks off, the CPU 10 proceeds to step 116 to perform a call service, otherwise proceeds to step 118. In step 118, the CPU 10 searches whether the time since connecting the line has reached a predetermined time which is a time-out time in the fax / tel mode. At this time, the CPU terminates when a predetermined time has elapsed, otherwise proceeds to step 120. In step 120, the central processing unit 10 searches whether a dual tone multi-frequency (hereinafter referred to as DTMF) signal is received from a telephone line as a user of a calling party inputs a dial key. In this case, when the DTMF signal is received, the CPU 10 proceeds to step 122, otherwise proceeds to step 108. In step 122, the CPU 10 searches whether the received DTMF signal is a DTMF signal for "*". At this time, the central processing unit 10 performs step (124) if the DTMF signal is a DTMF signal for "*", otherwise proceeds to step (108). In step 124, the CPU 10 searches whether the DTMF signal is received again. At this time, if the DTMF signal is received again, the CPU 10 proceeds to step 126, otherwise, the CPU 10 waits until the DTMF signal is received again. In step 126, the CPU 10 searches whether the received DTMF signal is a DTMF signal for "#". At this time, the central processing unit 10 proceeds to step 130 if the DTMF signal is not a DTMF signal for "# ", and temporarily stores digits according to the DTMF signal. If the DTMF signal is a DTMF signal for "# ", the CPU proceeds to step 128 and the digits stored temporarily are stored in a database provided in the memory unit 12 together with the current time. Save it.

Referring to the operation of the facsimile apparatus according to the flow chart of FIG. 2, first, when a predetermined number of rings are provided to the facsimile apparatus, the facsimile apparatus connects a telephone line and sends a guide message to the calling party. The user of the calling party who listened to the above guide message inputs a start button to send a message, and enters "*", "phone number" and "#" to request a call. At this time, the facsimile device automatically receives a message when a CNG tone is received according to the start button input of the calling party. When the DTMF signal is received by the caller inputting "*", the digit according to the input DTMF signal is stored together with the current time until the DTMF signal according to "#" is received.

The telephone number and time according to the call request are then output according to the request of the user of the facsimile apparatus. Referring to FIG. 3, which shows a flowchart of a method for providing call request information for providing information according to the call request, in step 200, the central processing unit 10 calls a user through the operation panel 26. Check whether to input the request list output command. At this time, if the user commands to output the call request list proceeds to step (204), otherwise proceeds to step (202) to perform the operation. In step 204, the central processing unit 10 outputs the call request information stored in the memory unit 12 as a call request list.

Here, the memory unit 12 stores the calling party's telephone number and the time of the call request. Accordingly, in the call request list, as shown in FIG. 4, the telephone numbers of the calling party making the call request are recorded in order.

As described above, the present invention can provide call request information of the calling party to the called party by providing only a device capable of synthesizing data according to the guidance message as a voice signal.
