FIG. 4 is a sub-flowchart of the dial input process in the automatic redial setting process of the facsimile apparatus 1 with the answering machine recording function according to the present embodiment. First, as shown in FIG.
In step 12, when the redial / pause key 50 is pressed after the function button 42 of the operation panel 25A is pressed, the automatic redial setting process is started. In step (hereinafter abbreviated as S) 1, the dial key 38 is pressed. It waits until one of them is pressed (S1: NO). And C
When any one of the dial keys 38 is pressed (S1: YES), the PU 12 performs a sub-process of the dial input process in S2.

Here, the sub-process of the dial input process will be described with reference to FIG. As shown in FIG. 4, first, in S15, when any of the dial keys 38 is pressed, the CPU 12 reads the dialed flag from the EEPROM 14, and determines whether or not the flag has been set, that is, "0" or "1". Is determined. If the read dialed flag is not set, that is, if it is "0", it is determined that the input is the first dial key input (S15: YES). 1 ”and again
It is stored in the EEPROM 14.

Subsequently, in S17, the CPU 12
The measurement time of the timer 19 is reset, and the time measurement is started. Then, in S18, the CPU 12 sends the data of the dial number corresponding to the input dial key to the exchange via the dial transmission means 16, the communication circuit 7, the line relay 4, the telephone line 20, and the like, and the main flow chart is displayed. Return.

In step S15, if the read dialed flag is set, that is, if it is "1", the CPU 12 determines that the input is not the first dial key input (S15: NO). In S19, the measured time is read from the timer 19, and the measured time is a second predetermined time T2 (in this embodiment,
The time T2, which is the second predetermined value, is about 30 seconds. ) It is determined whether or not: If the measured time is shorter than the time T2, that is, if the time T2 has not elapsed since the last input of the dial key (S19: NO), S1 is performed.
Step 7 and subsequent steps are executed. Also, this measurement time is the time T
In the case of two or more, that is, when the time T2 has elapsed since the previous dial key input (S19: YES), S
The processing after 18 is executed.

Next, as shown in FIG.
After executing the sub-process of the dial input process (S2), in S3, the measured time is read again from the timer 19, and the measured time is the first predetermined value T1 (in the present embodiment, the first predetermined value is used). The certain time T1 is about 30 seconds.) If the measured time is shorter than the time T1, that is, if the time T1 has not elapsed since the previous dial key input (S3: N
O), in S4, the CPU 12 determines whether or not a busy tone detection signal is input from the modem 22;
When the busy tone detection signal is input (S
4: YES), in S5, the dial number inputted via the dial key 38 is stored in the RAM 15, and then the line is opened via the line relay 4. Subsequently, in S6, after a predetermined period of time (about three minutes in this embodiment), the CPU 12 shifts to an automatic redialing process of reading out the dial number from the RAM 15 and redialing again, and ends the process.

In S3, if the measured time read from the timer 19 has passed the time T1 in S3 (S3: YES), or the busy tone detection signal has not been input from the modem 22 in S4. In the case (S4: NO), in S7, the communication circuit 7
The state shifts to a call state via the like.

Subsequently, in S8, the CPU 12 determines whether any of the dial keys 38 has been pressed. Then, when any one of the dial keys 38 is pressed (S8: YES), the processing after S2 is executed again. If none of the dial keys 38 has been pressed (S8: NO), a measurement time is read from the timer 19 in S9, and the measurement time is set to the first time.
It is determined whether or not the time is equal to or shorter than a predetermined time T1.

If the measured time is shorter than the time T1, that is, the time T has elapsed since the previous dial key input.
If 1 has not elapsed (S9: NO), S
4 and subsequent processes are executed. If the measured time read from the timer 19 has passed the time T1 in S9 (S9: YES), it is determined in S10 whether or not the hook is on-hook. If the hook is not on-hook (S10: NO), the processes from S8 are executed again. If it is on-hook (S10: YES), in S11, the line is opened via the line relay 4 and the process is terminated.

As described above in detail, in the facsimile apparatus 1 of the present embodiment, in the automatic redialing process, when the dial key 38 is inputted, if the first dial key 38 is inputted (S15: YES), After setting the dialed flag, the timer 19 is reset to start timing (S16, S17). If the input is not the first dial key 38 input and the time counted by the timer 19 has not elapsed the time T2 which is the second predetermined value, the timer 19 is reset and the time is restarted (S1).
5: NO, S19: NO, S17). Then, the dial data is sent to the exchange to end the dial input processing,
Until the time T1 of the timer 19 reaches the first predetermined value, the detection of the busy tone and the dial input processing are performed (S3, S4: NO, S7 to S9), and when the busy tone is detected (S4: YES), the line is released, and the process proceeds to the redial processing (S5, S6). Also,
In the case of on-hook, the line is released and the process is terminated (S10: YES, S11).

Therefore, every time one of the dial keys 38 is pressed, the time counted by the timer 19 is reset, and the time T counted by the timer 19 is the first predetermined value.
Since the busy tone detection processing is performed until the number reaches 1, after the dial input processing is completed, it is possible to always secure a fixed time for performing the busy tone detection processing, and it is possible to reliably detect the busy tone and to perform the automatic redial processing. Can be performed reliably. Further, even if there is no polarity reversal detection circuit for detecting the polarity reversal from the telephone exchange, it is possible to reliably detect the busy tone after the dial input processing is completed. When any one of the dial keys 38 is pressed, the timer 19
If the counted time of the timer 19 exceeds the second predetermined time T2, the counted time of the timer 19 is not reset.
If a predetermined time T2 or more has elapsed after the button 8 has been pressed, it is determined that an input error has occurred, and the automatic redial process can be stopped.

It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.

[0034]

As described above, according to the present invention, every time one of the dial keys is pressed, the measurement value of the measuring means (timer or the like) for measuring the time until the end of the busy tone detection processing is reset. It is possible to provide a communication terminal device which can always secure a fixed time after completion of the dial key input process and before completion of the busy tone detection process.
