In such a facsimile device with a built-in telephone, the calling party's telephone number input from the key input section is input into the dial section to perform a calling operation, and the calling party's telephone number is displayed on a display section provided in the device. It is also configured to be displayed.

However, some facsimile machines for home or personal use do not have a built-in telephone, and such facsimile machines often do not have a function to display the calling party's telephone number.

FIG. 6 is a block diagram showing the configuration of a facsimile machine 45 that does not have a built-in telephone. The facsimile device 45 is connected to a telephone line 46 , and connection and disconnection of the telephone line 46 is controlled by a line control section 39 .

[0005] The image signal received via the telephone line 46 is provided to the decoding section 42 via the line control section 39 and the transmission control section 38 . The decoding section 42 performs decoding processing such as data expansion, and provides the processed signal to the recording processing section 41. The recording processing unit 41 controls a recording unit 40 implemented by a thermal printer or the like, and records the received image signal on recording paper. At this time, the received image signal may be stored in the data storage section 37 implemented by a random access memory (RAM) or the like.

[0006] When transmitting an image signal, the telephone number of the other party's terminal device is inputted from the key section 31 . The input telephone number is detected by the Parne control section 32 and the main control section 36
The signal is applied to the dial section 44 via the . Dial section 44
controls the line control unit 39 based on the input telephone number and performs a calling operation. When the other party's terminal device responds and the line is connected, a predetermined communication protocol is performed, and then an image signal is transmitted.

That is, a document is read by a reading section 33 that includes a CCD (charge-coupled device), etc.
The reading processing section 34 performs binarization processing, and the encoding section 35 performs encoding processing such as data compression. The processed image signal is transmitted to the other party's facsimile machine via the transmission control section 38 and line control section 39. At this time, by storing the transmitted image data in the data storage section 37, timer transmission, broadcast communication, etc. can be performed.

Performs calling operation. When the other party's facsimile machine responds and the line is connected, a predetermined communication protocol is performed and an image signal is transmitted.

That is, a document to be transmitted is read by a reading unit 15 including a CCD (charge-coupled device), etc., the reading processing unit 14 performs binarization processing, and the encoding unit 13 converts the data into data. Encoding processing such as compression is performed. This encoded image signal is transmitted to the other party's facsimile machine via the transmission control section 5 and line control section 6. At this time, by storing the transmitted image data in the data storage section 4, it is possible to perform timer transmission, broadcast communication, etc., for example.

Further, the facsimile device 21 is connected to an LCD (liquid crystal display) 3, which displays the operating status of the facsimile device 21 and the calling party's telephone number from an external telephone 12, which will be described later.

Furthermore, an external telephone 12 is connected to the facsimile machine 21 . The external telephone 12 is connected to the dial pulse detection section 9 and the DTMF detection section 10,
Furthermore, it is connected to the hook detection section 8. When the handset of the external telephone 12 is picked up and placed in a so-called off-hook state, the off-hook state is detected by the hook detecting section 8, and the external telephone 12 is therefore connected to the facsimile machine 21.
and is connected to an exchange (not shown) via a telephone line 11.

Thereafter, when the calling party's telephone number is input by operating the dial or push button of the external telephone 12, the telephone number is detected by the dial pulse detector 9.
Alternatively, it is detected by the DTMF detection section 10 and provided to the main control section 7. The main control section 7 supplies the detected calling party telephone number to the panel control section 2 to display it on the LCD 3, and also to the dial section 19. The dialing section 19 dials the line control section 6 based on the given calling party telephone number.
and performs calling operations.

FIG. 2 is a flowchart illustrating the operation when making a call when the external telephone 12 is a push-button dial telephone (so-called push-button type), and FIG.
It is a timing chart showing the operation. When the hook detection unit 8 detects that the external telephone 12 is in an off-hook state in step a1 (see FIG. 3(1)), the LCD 3 is initialized in step a2 and preparations are made to display a telephone number.

In step a3, the DTMF detection unit 10 determines whether the DTMF shown in FIG. 3(2) has been detected. If detected, the process proceeds to step a4; if not detected, the process proceeds to step a9.

In steps a4 to a6, it is checked whether the detected DTMF transmission time W1, minimum pause W2, and period W3 are within the specified range shown in Table 1 below. If all the detected DTMFs are within the specified range, the process proceeds to step a7; otherwise, the process proceeds to step a9.

When the hook detection unit 8 detects that the external telephone 12 is in an off-hook state in step b1 (see FIG. 5(1)), the LCD 3 is initialized in step b2 and preparations are made to display a telephone number.

In step b3, it is determined whether the dial pulse detection section 9 has detected a dial pulse. If detected, the process proceeds to step b4; if not detected, the process proceeds to step b8.

In step b4 and step b5, the make rate of the detected dial pulse, the minimum pose W
4 is within the specified range shown in Table 2 below. If all the detected dial pulses are within the specified range, the process proceeds to step b6; otherwise, the process proceeds to step b8.

[0033]

[Table 2]

The number of dial pulses and the dial signal are the same. However, "0" is 10 pulses. Dial pulse speed refers to the number of pulses that last per second. The dial pulse make rate refers to the ratio of time between dial pulse contact (make) and disconnection (break), and is defined by Equation 1 below.

[0035]

[Equation 1] Engagement time ÷ (engagement time + interruption time) x 100% = dial pulse make rate Minimum pause refers to the minimum value of the pause time between adjacent pulse trains.

In step b6, the detected dial pulse is regarded as a dial number and displayed on the LCD 3. In step b7, the detected number is stored in the data storage section 4.

In step b8, it is determined whether or not the input of the telephone number has been completed, based on, for example, whether there has been silence for a predetermined period of time. Once the telephone number has been entered, a call is made, and if the other party answers, the call is made. If it is determined that the input has not been completed, the process returns to step b3 and the next dial pulse is detected.

In step b9, the hook detection section 8 detects whether or not the on-hook state has been reached. When the on-hook state is detected, the L
The display of CD3 is cleared and the telephone number display operation is completed.
