However, even when the other party does not transmit a CNG signal when the line is closed by picking up the handset and the other party is talking, the same as the CNG signal. Noise having various signal components may be erroneously detected as a CNG signal. In that case, a facsimile original may be automatically received, which may surprise a user during a call.

The present invention has been made in view of the above problems, and an object thereof is to erroneously detect a signal component similar to the facsimile activation signal as a facsimile activation signal during a call with the other party. An object of the present invention is to provide an excellent communication device capable of preventing a malfunction such as automatically shifting to a reception state of a facsimile document.

[0006]

In order to achieve the above object, in the communication device according to the first aspect, a telephone function and a facsimile function are switched and connected to an external communication line and transmitted from the other party. In a communication device that enables facsimile reception by detecting a facsimile activation signal, a facsimile activation signal detection unit that detects a facsimile activation signal during a call with the other party,
When a facsimile activation signal is detected, a storage unit that stores the facsimile activation data, a determination unit that determines whether to read the facsimile activation data from the storage unit, and a determination unit that determines to read the facsimile activation data, And a control means for performing facsimile reception based on the facsimile activation data stored by the storage means.

In the communication device having the above structure, when the facsimile activation signal detection means detects the facsimile activation signal during a call with the other party, the storage means detects that the facsimile activation signal is detected. Unless the data is stored and the judgment means judges that the facsimile starting data is read out, the facsimile reception is not automatically started. Therefore, even if a noise having a signal component similar to that of the facsimile activation signal is erroneously detected as the facsimile activation signal, it is possible to prevent an erroneous operation such as automatically shifting to the facsimile reception state.
For example, if the determination means determines that the facsimile activation data should be read because the handset is lowered or a dedicated button such as a predetermined operation key or cut button is pressed, the facsimile activation data is stored in the storage means. If so, the process shifts to facsimile reception. Even if the facsimile activation signal detection means erroneously detects noise having a signal component similar to that of the facsimile activation signal as the facsimile activation signal, it shifts to the facsimile reception state after the end of the call. Does not happen.

Further, in the communication device according to claim 2, in the communication device according to claim 1, when the end of the call with the other party is detected, the determination means determines the facsimile activation data stored in the storage means. The feature is that it is determined to read. According to the communication device of the second aspect, when the end of the call with the other party is detected, the determination means determines to read the facsimile activation data, and the control means stores the facsimile activation data in the storage means. For example, since the state automatically shifts to the facsimile reception state, the user wishes to receive the facsimile.

Further, according to the communication apparatus of claim 3, in the communication apparatus of claim 1 or 2, when the facsimile activation signal detecting means detects a facsimile activation signal during a call with the other party. In addition, the notification means for urging the end of the call state with the other party via the external communication line is provided, and when the end of the call with the other party is detected, the determination means determines to read the facsimile activation data. To do. In this way, when a fax activation signal is detected during a call, for example, a display device such as "Facsimile reception. Please put the handset on." Is displayed to inform the user of the status of the call with the other party. Notify to prompt termination processing. Therefore, when the facsimile activation signal detecting means detects the facsimile activation signal, the user does not know how to operate to shift to the facsimile reception and prevents the user from continuing the call as it is. be able to.

According to a fourth aspect of the communication apparatus, in the communication apparatus according to the second or third aspect, the activation is performed by measuring a predetermined time based on the facsimile activation data stored in the storage means. It is characterized in that an erasing means for erasing the facsimile start data stored in the storage means is provided when the communication partner disconnects the call before the timer is operated and the time is not up.
As a result, if the communication partner disconnects the call before the time measurement by the start timer is started and before the time is up, the facsimile start data stored in the storage means is deleted, so that the same signal component as the facsimile start signal is generated. It is possible to prevent the shift to the facsimile reception when a voice or noise having the above is erroneously detected as the facsimile start signal.

According to a fifth aspect of the communication apparatus, in the communication apparatus according to any one of the second to fourth aspects, only a predetermined time is set based on the facsimile activation data stored in the storage means. A activating means for activating a time measuring timer is provided, and when the call with the other party is not completed within a predetermined time, erasing means for erasing the facsimile activation data stored in the storage means is provided. Thus, the time measurement by the activation timer is started, and if the call with the other party is not completed within the predetermined time, the facsimile activation data stored in the storage means is erased. Therefore, when a voice or noise having the same signal component as the facsimile activation signal is erroneously detected as the facsimile activation signal, it is possible to prevent the transition to the facsimile reception.

Further, according to the invention of claim 6, in the communication device according to any one of claims 2 to 5, when the call with the other party is finished, the facsimile activation data is stored in the storage means. If it is not stored, the measurement timer that measures the time for the predetermined time is operated, and it is determined whether or not the facsimile start signal detecting means detects the facsimile start signal within the predetermined time. If the facsimile start signal is detected, the facsimile start signal is detected. A second control means for performing a receiving operation is provided. As a result, when the call with the other party ends, and the facsimile activation data is not stored in the storage means, the second control means determines whether or not the facsimile activation signal detection means detects the facsimile activation signal, When the facsimile start signal is detected, the facsimile reception operation is performed. Therefore, if the storage device does not store the facsimile activation data at the end of the call with the other party, even if the user disconnects the line, the line is not immediately disconnected, and the facsimile is sent within a predetermined time thereafter. When the activation signal is detected, it is possible to shift to facsimile reception.

Next, with reference to FIG. 5, a description will be given of a process for detecting a facsimile start signal during a call in the facsimile apparatus according to this embodiment. Figure 5
In step (hereinafter abbreviated as S) 1, as shown in FIG.
The facsimile activation signal detector 28a determines whether to detect the facsimile activation signal (CNG) (S).
2). The facsimile activation signal detector 28a of the main body 1 is
When the facsimile start signal (CNG) is detected (S2: YES), the CPU 25 starts the start timer (CNG detected timer) 17a for measuring a predetermined time.
To operate. That is, when the facsimile activation signal detector 28a detects the facsimile activation signal (S2: YES), the CPU 25 turns on the detected flag of the RAM 17 serving as a storage unit (stores the facsimile activation data in the RAM 17) (S3). ). Next, the CPU 25 sets the timer of the activation timer 17a (S4).

Then, a display prompting the end of the talking state with the other party (for example, an operation of placing the handset or the handset 31 of the main body 1 and a pressing operation of the call end button) is displayed on the display 2 of the main body 1 or the handset 31. The liquid crystal display 31 is displayed and the handset or the handset 31 is vibrated for a predetermined time (3 seconds) (S5). It should be noted that an "alarm sound" such as a "voice message" or a buzzer may be generated. Next, the CPU 25 determines whether or not the activation timer 17a has timed out (expired) (S6).

The process in S5, that is, the process for displaying the liquid crystal display 31 or the like of the handset 31 to prompt the user to end the call and vibrating the handset 31 or the like for a predetermined time is as follows:
This is a process to prevent the user from continuing the call because he / she does not know what to do in order to shift to the facsimile reception when the facsimile start signal is detected. If it detects "," for example, "Facsimile reception. Please place the handset." On the liquid crystal display 31 of the cordless handset 31, etc., and prompt the user to end the call state with the other party. To inform. The display on the liquid crystal display 31 or the like of the child device 31 constitutes an informing means for prompting the end of the talking state with the other party.

When the start-up timer 17a has timed out (S6: YES), the CPU 25 turns off the detected flag of the RAM 17 (deletes the facsimile start-up data) (S7), and the liquid crystal display 31 of the handset 31 or the like. The display prompting the end of the call is erased (S9). That is, based on the facsimile start signal, the start timer 1
7a operates and when a predetermined time has passed, that is, if the call is not completed within the predetermined time, the detected flag of the RAM 17 is turned off. The CPU 25 constitutes an erasing means for erasing the facsimile starting data stored in the RAM 17.

When the activation timer 17a has not timed out (S6: NO), it is determined whether the communication partner has disconnected the line (S8). When the communication partner disconnects the line (S8: YES), the CPU 25 causes the RAM 17
The detected flag of is turned off (S7), and the handset 3
The display prompting the end of the call on the liquid crystal display 31 of No. 1 is erased (S9). Specifically, as a method of detecting the line disconnection of the communication partner, it is performed by detecting a busy tone from an exchange (not shown) via the NCU 23.

Therefore, the facsimile start signal detection unit 2
When the communication partner disconnects the line within a predetermined time, for example, when 8a erroneously detects a voice or noise having a signal component similar to the facsimile start signal as a facsimile start signal, or the call ends within the predetermined time. Even if it does not, it is possible to prevent the automatic shift to facsimile reception.

When the communication partner does not disconnect the call (S8: NO), it is determined whether or not there is a line disconnection request due to the user placing the receiver or the like (S10). The judgment means for judging whether or not there is a line disconnection request constitutes a judgment means for judging whether or not the ON / OFF state of the detected flag of the RAM 17 is checked (whether or not the facsimile start data is read from the RAM 17). , If the user hangs up the handset, it is judged that a line disconnection request has been made. If there is no line disconnection request (S10: NO), it is determined that it is not necessary to check the ON / OFF state of the detected flag of the RAM 17, and the process returns to S2.

When the user puts the handset on and there is a line disconnection request (S10: YES), the facsimile activation signal detector 28a detects the facsimile activation signal, and the RAM 17
It is determined whether or not the detected flag of is in the ON state (S11). If the detected flag is ON (S
11: YES), facsimile reception is immediately performed (S1)
2).

When the detected flag is OFF (S11: NO), the measuring timer 17b starts measuring a predetermined time (S13), and the facsimile activation signal detecting section 2 is started.
It is determined whether or not 8a detects the facsimile start signal (S14). When the facsimile start signal is not detected (S14: NO), it is determined whether the measurement timer 17b has timed up (S15). Measurement timer 17b
If the facsimile start signal is detected before the time is up (S15: NO) (S14: YES), the facsimile is immediately received (S12).

This is because when the detected flag is OFF (when the facsimile activation data is not stored in the RAM 17), even when the user disconnects the line, when the facsimile activation signal is detected within the predetermined time. Is for enabling the shift to facsimile reception. When the facsimile activation signal detection unit 28a does not detect the facsimile activation signal (S14: NO) and when the measurement timer 17b times out (S15: YES), the line is disconnected (opened) (S16).

As described above, according to the present invention, in the facsimile machine, the telephone function and the facsimile function are switched and connected, and the facsimile activation signal detecting means 28a is transmitted from the other party through the public telephone line 30. A facsimile activation signal can be detected. When the facsimile activation signal detection unit 28a detects the facsimile activation signal during a call with the other party that enables facsimile reception, the CPU 25 stores the facsimile activation data in the RAM 17 (RAM17 when the facsimile activation signal is detected). Whether or not the facsimile start data is read from the RAM 17 (ON / OFF of the detected flag of the RAM 17).
Whether to check the condition). And NCU23
When the end of the call with the other party is detected, it is determined that the facsimile start data is read from the RAM 17,
Facsimile reception is performed based on the facsimile activation data stored in 17.

As a result, even if the facsimile activation signal detecting means 28a detects the facsimile activation signal during a call with the other party, if the CPU 25 determines that the facsimile activation data is not read, the facsimile reception is automatically started. Therefore, even if a voice or noise having a signal component similar to that of the facsimile activation signal is erroneously detected as the facsimile activation signal, it is possible to prevent an erroneous operation such as automatically shifting to the facsimile reception state.

The present invention is not limited to the above embodiment, and it goes without saying that various improvements and modifications can be made without departing from the spirit of the present invention. For example, as a method of detecting the end of a call, polarity reversal may be detected.
Further, as a determination method for determining whether to read the facsimile activation data from the RAM, for example, the determination may be made based on whether a specific key or a dedicated button is operated. As shown in FIG. 6, the manual operation key 45 is arranged in the facsimile apparatus, and when the manual operation key 45 is turned on, it is determined that the facsimile start data is read,
You may shift to a facsimile reception state. A specific key operation other than the dedicated button may be performed.
