[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power saving standby state for waiting for a call signal from a telephone line in a state where power supply to at least the control means is cut off, and to supply power to at least the control means. When one of the normal standby states for waiting for the arrival of a call signal from the telephone line in the operable state is set as a standby state, and a call signal from the telephone line is detected during the standby state for one of the two, the telephone The present invention relates to a facsimile apparatus having an automatic reception mode for performing an automatic reception operation by connecting to a line.

2. Description of the Related Art In recent years, devices such as information processing devices and communication devices have been reduced in power consumption, and devices that have achieved this power saving have appeared. One such device is a facsimile machine. As this facsimile machine, at least a power saving standby state for waiting for a call signal from a telephone line in a state where power supply to the control unit is shut off and at least a control unit. One of normal standby states for supplying power and waiting for a call signal from a telephone line in an operable state is set as a standby state, and from the telephone line during one of the standby states. Some have an automatic reception mode in which an automatic reception operation is performed by connecting to a telephone line when a call signal is detected.

In this automatic reception mode, when a call signal from the telephone line is detected in a power saving standby state, power is supplied to the control means by using the call signal as a trigger, and the control means is shifted to an operable state, and the control is performed. The means starts counting the number of times the call signal has been detected after transitioning to the operable state, and controls the connection to the telephone line when the counted number of times the detected call signal reaches the required number of times of detection. On the other hand, when a call signal from the telephone line is detected during the normal standby state, the control means starts counting the number of times of detection of the call signal from the time of detection of the call signal from the telephone line, and detects the counted call signal. When the count reaches the request detection count,
Control to connect to telephone line. The number of request detections is set to the same number of times when the power saving standby state is set as the standby state and when the normal standby state is set.

[0004]

However, when the power saving standby state is set as the standby state, power is supplied to the control means by using a call signal as a trigger to shift the control means to an operable state. Since the counting of the number of times of detection of the call signal is started later, the actual number of arrivals of the call signal becomes one more than the number of times of detection of the request. On the other hand, in the case of the normal standby state setting, since the power is supplied to the control means at least in the normal standby state, counting of the number of times of detection of the call signal from the time of detection of the call signal from the telephone line is performed. Is started, the actual number of incoming call signals becomes the same as the number of request detections. As described above, the actual number of call signals from the telephone line up to the connection to the telephone line in the power saving standby state setting is one more than the actual number of call signal arrivals in the normal standby state setting. That is, the number of times of ringing in response to the call signal is different between the case of the power saving standby state setting and the case of the normal standby state setting.
Therefore, it is not possible to shift to the automatic reception operation with the same number of ringing times as the set number of detected requests, and the reliability in the automatic reception mode may be impaired.

An object of the present invention is to provide a facsimile apparatus which does not impair the reliability of the automatic reception mode.

After the H relay 36 is turned off or on, the process proceeds to step S7, in which the signal generated by the key operation on the operation unit 32 is fetched via the signal line 32a, and registration in the ringing signal number registration circuit 30 is selected. Determine whether or not. When registration in the ringing signal number registration circuit 30 is selected, the process proceeds to step S8, and the number of request detections indicating the number of ringing signal detections required before the CML relay 42 is turned on is registered in the ringing signal number registration circuit 30. .

In the following step S10, a signal from the energy saving standby selection switch 22 is fetched via the signal line 22a, and it is determined whether or not the energy saving standby mode is selected based on the signal, and the energy saving standby mode is selected. If not, step S4 described later

The power supply control circuit is instructed to cut off the power supply of the power supply.

Next, proceeding to step S14, a signal from the activation factor detection circuit 26 is fetched via the signal line 26a, and it is determined based on this signal whether an activation factor has been detected. If the activation factor is not detected, the process returns to step S4, and the process from step S4 is repeated. On the other hand, when the activation factor is detected, step S

If the activation factor is not the detection of a call signal, the process proceeds to step S20, performs other processing, and returns to step S2 again.

If the activation factor is the detection of a call signal, FIG.
As shown in (5), the process proceeds to step S22, where the parameter n registered in the ringing signal number registration circuit 30 is read,
The count value k equal to the parameter n is stored in the counter k, and in the subsequent step S24, the count value k of the counter k

Next, the process proceeds to step S26, in which the count value k of the counter k is decremented by one, and
At 28, it is determined whether or not the count value k of the counter k is 0 or less. If the count value k is not 0 or less, the process proceeds to step S30, and it is determined whether or not the next call signal is detected within a predetermined time (for example, 4 seconds). If the next call signal is not detected within the predetermined time, the process returns to step S2 (shown in FIG. 3) again. If the next call signal is detected within the predetermined time, the process from step S26 is performed, and the count value k becomes It repeats until it becomes 0 or less or the next ringing signal is not detected within a predetermined time.

If it is determined in step S28 that the count value k is equal to or less than 0, it is determined that the number of times the call signal has been detected until the CML relay 42 is turned on has reached the required number of times, and the flow advances to step S32. , Signal line 20a

If it is determined in step S10 that the energy saving standby mode has not been selected, the process proceeds to step S40, as shown in FIG. 5, in which the power supply control circuit is instructed to supply power to all the blocks, and then continues. In step S42, the parameter n registered in the call signal number registration circuit 30 is read, and a count value k equal to the parameter n is stored in the counter k.

Next, proceeding to step S44, the signal from the call signal detection circuit 28 is fetched via the signal line 28a, and it is determined whether or not a call signal has been detected. Then, the other processes are executed, and the process returns to step S2 (shown in FIG. 3).

Return to

As described above, in the automatic reception mode, when the transition from the energy saving standby state to the operable state is performed with the detection of the call signal as a trigger, the transmission from the telephone line 2a is performed after the transition to the operable state. The counting of the number of detected call signals is started, and when the counted number of detected call signals reaches the first required number of times of detection (n-1; n is an integer of 2 or more), connection with the telephone line 2a is performed. So that
When a call signal from the telephone line 2a is detected in the normal standby state, counting of the number of times of detection of the call signal is started from the time of detection of the call signal, and the counted number of times of detection of the call signal is equal to the second time. When the request detection count (n) is reached, control is performed so that connection with the telephone line 2a is established. Therefore, detection is performed regardless of whether the standby state of the energy saving standby state or the normal standby state is set in the ringing incoming call mode. The operation can be shifted to the automatic reception operation with the same number of ringing times as the number of ringing signals, and there is no possibility that the reliability in the automatic reception mode is impaired.

Since the first and second request detection counts are represented by the parameter n, each request detection count can be easily set without distinguishing the first and second request detection counts. Since the parameter n for indicating the number of times of request detection is registered in the call signal number registration circuit 30 by a key operation of the operation unit 32, the number of times of request detection desired by the user can be set.

Further, since the default value of the parameter n is 2, it is possible to prevent the parameter n from being forgotten to be registered.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing a control operation by the control circuit in the facsimile apparatus according to the second embodiment of the present invention. Note that the configuration of the present embodiment is the same as the configuration of the above-described first embodiment, and a description thereof will be omitted.

This embodiment is different from the first embodiment in that
When the ringing mode is set and the transition from the energy saving standby state to the operable state is performed by using a call signal as a trigger, the first request detection count (n-1) is set to the ringing mode and the normal standby state is set. When the ringing signal from the telephone line 2a is detected when the setting is set, the second request detection count (n) is changed from the energy saving standby state to the operable state by using the ringing signal as a trigger when the non-ringing incoming call mode is set. When the mode is shifted to and when a ringing signal from the telephone line 2a is detected while the silent reception mode is set and the normal standby state is set, the third request detection number (n) is set. Is different. This parameter n is a positive integer of 2 or more, and 2 is set as a default value of the parameter n.

Next, the control operation of the control circuit 20 according to the present embodiment will be described with respect to portions different from the first embodiment described above.

After the execution of step S22 shown in FIG.
As shown in (2), the process proceeds to step S52, in which a signal from the non-ringing / ringing switch 24 is fetched via the signal line 24a, and it is determined whether or not the ringing mode is selected based on this signal. When the ringing mode is selected, it is determined that the transition from the energy saving standby state to the operable state has been performed by using the calling signal as a trigger when the ringing mode is set, and step S24 shown in FIG. 3 is performed.
To rewrite the count value k of the counter k to (k-1), that is, set the number of times of request detection one less.
When the ringing mode is not selected, that is, when the non-ringing mode is selected, it is determined that the transition from the energy saving standby state to the operable state has been performed by using the calling signal as a trigger when the non-ringing mode is set. 3
Skips the step S24 shown in (1) and proceeds to the step S26, and without rewriting the count value k of the counter k to (k-1), the telephone line 2a when the ringing mode is set and the normal standby state is set. The same number of request detections (n) as in the case where a call signal is detected is set.

As described above, by adding step S52, the first request detection count (n- 1), if a ringing signal is detected from the telephone line 2a when the ringing mode is set and the normal standby state is set, the second request detection count (n) is set to the non-ringing mode. When a ringing signal is used as a trigger at the time of setting to shift from the energy saving standby state to the operable state, and when a ringing signal from the telephone line 2a is detected when the silent reception mode is set and the normal standby state is set. Is set to a third request detection count (n).
Therefore, even when the standby state of the energy saving standby state or the normal standby state is set in the ringing reception mode, it is possible to shift to the automatic reception operation with the same number of rings as the number of incoming call signals. Also, in the non-ringing incoming call mode, the number of requests detected for each of the standby states of the energy saving standby state and the normal standby state is the same, so the number of call signals detected before connection with the telephone line 2a is different. Since the ringing is prohibited in the non-ringing incoming call mode, the user is not distrusted with the reliability of the automatic receiving mode due to the difference in the number of detected call signals.
