Abstract

(57) [Abstract] [Purpose] It is possible to notify the caller of the other party's telephone number in a communication management report even when a manual FAX transmission is performed by an external telephone in a FAX machine capable of connecting to an external telephone. [Construction] An external telephone off-hook and a telephone number detection circuit 8 are provided in the FAX machine, and the destination telephone number is detected by the telephone number detection circuit 8 during manual FAX transmission from an external telephone, and the result is sent to the CPU 7 for storage. By setting, the destination telephone number is added to the FAX transmission result in the communication management report after all data is transmitted, and the result is output.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fax machine with a telephone number detecting function for managing transmission in manual fax transmission of a fax machine having a terminal for connecting an external telephone.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram of a conventional FAX machine. In FIG. 2, 1 is a terminal for connecting a telephone line, 2 is a terminal for connecting an external telephone, 3 is a switching circuit for switching between an NCU circuit inside the FAX apparatus and an external telephone by a control signal from a CPU, and 4 is a call from the FAX apparatus. Network control unit (NCU) circuit for connecting a telephone line, 5 is a telephone number key and FAX for making a call
Key scan circuit for start / stop key detection, 6
Is a key input board for telephone numbers, FAX start / stop, off-hook, etc., 7 is a main CPU, and 9 is an off-hook detection circuit for an external telephone. An operation of manual FAX transmission in the FAX apparatus configured as above will be described. 1) Manual FAX transmission using the internal telephone The caller off-hooks the internal telephone by the handset or the off-hook switch of the key input board 6. When the CPU 7 detects the off-hook of the internal telephone, the CPU 7 sets the switching circuit 3 to the A side and waits for the telephone number input from the key input board 6. Next, when a telephone number is input from the key input board 6, the CPU 7 controls the NCU circuit 4 to send a dial signal to the telephone line. The exchange analyzes the telephone number from this dial signal and calls the fax machine on the other side. When the called side receives the call signal, the called side responds to the calling side with a response signal. When the sender FAX receives the response signal, the NCU
Ring the internal telephone handset through circuit 4. The caller recognizes from this sound that he / she is connected to the other party's FAX machine, and turns on the FAX transmission start switch of the key input board 6. The CPU 7 detects the FAX start by the key scan circuit 5 and starts transmitting the FAX data, and after transmitting all the data, automatically turns on the hook and disconnects the line. Thus, C
Since PU manages all calling functions of the telephone, FAX
The recipient's telephone number can be added to the transmission result and output.

2) Manual FAX transmission using an external telephone When the caller goes off-hook on the external telephone, the external telephone off-hook detection circuit 9 on the FAX machine side works to notify the CPU 7 of the off-hook. The CPU 7 sets the switching circuit 3 to the B side and FA
X Waits for the start of transmission and does not participate in the calling function. Dialing signal is sent by external telephone and FA on the other side
After confirming the connection with X, the caller turns on the FAX transmission start on the FAX machine side. When the CPU 7 detects the FAX transmission start by the key scan circuit 5, the switching circuit 3 is set to the A side to start the FAX data transmission, and after the transmission of all the data, the CPU 7 automatically turns on the hook to disconnect the line. In this way, CP
Since U7 is not involved in the calling function of the telephone, when the external telephone is used, it is impossible to add the destination telephone number to the transmission result and output it. For this reason, it is impossible to output the destination telephone number of the FAX transmission NG which must be notified to the caller.

[0004]

However, in the above-mentioned conventional fax machine, the fax transmission result (OK / NG)
Has a function of notifying the caller as a FAX transmission management report, but when the internal telephone is used as described in the above-mentioned conventional technique, the CPU is directly involved in the calling function, so the telephone number is included in the FAX transmission result. However, if an external telephone is used, the telephone number cannot be added. Therefore, especially when using an external telephone, FAX transmission N
In the case of G (for example, a piece of paper on the called side), there is no information about which destination was sent and NG, so another sender may send to the same NG destination without knowing it. There was a problem. The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a FAX machine with a telephone number detection function that can give a destination telephone number even when an external telephone is used.

[0005]

In order to achieve the above object, the present invention provides a fax number with a telephone number detecting circuit for detecting a telephone number transmitted on a telephone line in manual fax transmission using an external telephone. , The other party's telephone number can be detected.

[0006]

Therefore, according to the present invention, the destination telephone number from the external telephone can be detected by the FAX device, and the destination telephone number can be added to the FAX transmission result to notify the caller.

1 is a block diagram of a fax machine according to an embodiment of the present invention. In FIG. 1, 1 is a telephone line connection terminal, 2 is an external telephone connection terminal, and 3 is a CP
A switching circuit for switching between an NCU circuit inside the FAX machine and an external telephone by a control signal from U, 4 an NCU circuit for making a call from the FAX machine and connecting a telephone line, 5 a telephone number key for making a call and FAX start / Key scan circuit for detecting stop key, 6 is telephone number, FAX
Key input boards for start / stop, off-hook, etc., 7 is a CPU, and 8 is an external telephone off-hook and telephone number detection circuit.

The operation of manual FAX transmission in the FAX apparatus configured as described above will be described. 1) Manual FAX transmission using an internal telephone Since the operation is the same as that of a conventional FAX apparatus, its explanation is omitted. 2) Manual FAX transmission using an external telephone When the caller off-hooks the external telephone, the off-hook detection circuit 8 on the FAX machine side works to notify the CPU 7 of the off-hook, and the CPU 7 sets the switching circuit 3 to the B side. When the caller sends a dial signal to the telephone line by an external telephone, F
The telephone number detection circuit 8 of the AX device operates and the CPU 7 recognizes the telephone number and stores it in the memory. After confirming the connection with the other party's FAX, the caller turns ON the FAX transmission start of the key input board 6. When the CPU 7 detects the FAX transmission start by the key scan circuit 5, the switching circuit is set to the A side to start the transmission of the FAX data, and after the transmission of all the data, the CPU 7 automatically turns on the hook to disconnect the line. Thus, since the CPU manages all the calling functions of the telephone, it is possible to add the destination telephone number to the FAX transmission result and output it.

[0009]

As is apparent from the above-described embodiments of the present invention, since the FAX device can detect the dial signal from the external telephone, even in the case of manual FAX transmission using the external telephone, the destination telephone number is indicated in the communication management report. The effect is that the sender can be notified and unnecessary transmission errors can be prevented.
