Further, in the power supply control device for a facsimile apparatus disclosed in Japanese Patent Laid-Open No. 1-119813, when the call signal input from the line is detected by the call signal detection circuit, the main power is turned on to save power consumption. I am trying. In addition,
In the electronic device disclosed in Japanese Patent Laid-Open No. 3-105408, power supply is reduced by stopping clock supply during a period in which a predetermined control process is not required.

[0003]

However, in the prior art disclosed in Japanese Patent Laid-Open No. 57-168573, there is shown a concrete means for turning on the main power supply when the time for performing time-specified transmission is reached. However, since the prior art disclosed in Japanese Patent Laid-Open No. 1-119813 only shows turning on the main power when an incoming call arrives, a power saving control can be performed in a facsimile device that performs time-specified transmission. There was a problem I couldn't do. Further, the conventional technique disclosed in Japanese Patent Laid-Open No. 3-105408 has insufficient power saving effect. The present invention is for solving the above-mentioned problems of the conventional technology, and can perform power saving control in an information device that starts a predetermined operation at a specified time, particularly in a facsimile apparatus that performs time-specified transmission.

According to the invention of claim 3, in the above, the next predetermined operation is not started even after the lapse of the first predetermined time from the end of the predetermined operation, and the time until the next designated time is the second predetermined time. When the time is longer than the time, the main power supply is stopped again. According to a fourth aspect of the invention, in the means according to the second aspect, a sub-power source is provided to supply power to a data memory that stores image information and the like while the main power source is stopped.

[0005]

With the above-described means, the power supply control device according to the first aspect stops the main power supply until the designated time at which the main body executes the predetermined operation, and the designated time is reached. The main power supply can be started at this time. According to the second aspect of the present invention, the main power supply can be stopped until the designated time for executing the time designated transmission is reached, and the main power supply can be started when the designated time is reached. In the power supply control device or the facsimile device according to claim 3, the next predetermined operation is not started even after the lapse of the first predetermined time from the end of the predetermined operation, and the time until the next designated time is the second time.

10. A control memory 11 for storing various control information such as the time at which the time designated transmission is performed is provided.

The control means 4 is provided with a CPU and a ROM containing a program, and realizes a designated time setting means for setting the designated time in the clock means 2.
Further, the clock means 2 and the control memory 11 are
Since power is supplied from a battery (not shown), the clock does not stop even when the commercial power is cut off, and various control information in the control memory 11 is not lost. A main power source and a sub power source are generated from the commercial power source (a generator is not shown), and if the main power switch 6 connected to the main power source is in the ON state (connection state), the main power source is denoted by 1 to 1. 5, 7
Is supplied to all the constituent blocks indicated by 11 to 11 (only the power supply line to the control means 4 is shown in the figure). Further, the sub power source is supplied only to the power source control means 1, the data memory 3, the low power key 21 in the operation unit 5, and the NCU 7. The data memory 3 is a DRAM having a self-refresh function.
It is composed of

FIG. 2 is a block diagram showing the details of the operation unit 5. As shown in the figure, the operation unit 5 includes a low power key 21 for giving an instruction to the power source control means 1, a ten-key 22 for inputting the terminal number of the other party, a one-touch key 23 for designating a registered terminal number, and a start key. 24, stop key 25, function key 26, cursor key 27, display 28 and the like. FIG. 3 is a state transition diagram showing the state transition of the above embodiment, and FIG. 4 is a timing chart of the power supply control state. The operation of the present invention will be described below with reference to FIGS.

At first, assuming that the commercial power source of the facsimile apparatus shown in FIG. 1 is in an off state (power off state), the main power source and the sub power source at this time are not supplied (shown at Low level in FIG. 4). Is. When the commercial power source is turned on in such a state (when the power is turned on in FIG. 4), the sub power source is automatically in the supply state (indicated by a high level in FIG. 4), and the power source control means 1 By this, the main power switch 6 is turned on, and the main power is also turned on (FIG. 4).

In this way, the power-on process is executed by the control means 4 (S1). That is, the control means 4 performs various initial settings, clears the data memory 3, and the like, and enters a standby state when the processing is completed (S2). Then, the control means 4 acquires the current time at that time from the clock means 2 and stores it in a predetermined area of the control memory 11. After that, the control unit 4 periodically acquires the current time, and the elapsed time from the time stored in the predetermined area is previously stored in the control memory.
It is monitored whether or not the predetermined time A set to 11 has been reached (S2). When the elapsed time reaches the predetermined time A, the control means 4 outputs a sleep signal to the power supply control means 1 to instruct the power supply control means 1 to shift to the low power mode, and then the power supply control means 1
Turns off the main power switch 6 to stop the supply of main power. That is, the low power state (S3) is set. On the other hand, when the key input from the operation unit 5 is recognized or the incoming call is detected by the NCU 7 before the elapsed time reaches the predetermined time A, the operation / operation state (S5) is entered.

In the example shown in FIG. 4, the operation for time designated transmission is performed before the elapsed time reaches the predetermined time A, and the time designated transmission is performed from the ten-key pad 22 in the operation unit 5. The designated time and the terminal number of the other party (destination) are input, and these are controlled by the designated time setting means.
The transmission image information is set in a predetermined area 11 and is read by the reading unit 9 and stored in the data memory 3. In addition,
As shown in FIG. 4, during this time, the main power supply continues to supply power, and the sub power supply continues to be supplied as long as the commercial power supply is turned on. The designated time setting means manages whether or not the designated time has already been set in the clock means 2, and if not, sets the designated time set in a predetermined area of the control memory 11 from the operating section 5. Set to 2. If a plurality of designated times are set in the predetermined area,
A time later than the current time at that time and closer to the current time is set. Further, the designated time set in the clock means 2 is cleared by the clock means 2 itself when the present time reaches that time.

When the operation and the operation are completed, the standby state is resumed (S2), and when the predetermined time A has passed in the standby state, the main power supply is stopped as described above, and the low power mode (low power state) is set. Enter (S3). The operation unit 5
It is also possible to forcibly enter the low power mode by pressing (turning on) the low power key 21 therein. Further, instead of unconditionally switching to the low power mode when the standby state has elapsed for a predetermined time, it is possible to switch to the low power mode only when the time from that time to the next time designated transmission is the predetermined time B or more. is there. This is because when the standby state has passed the predetermined time A, the control means 4 obtains the next time designated transmission time and the preset predetermined time B from the control memory 11, and sets the predetermined time B at the current time at that time. It is realized by comparing the added time and the next time designated transmission time.

Since the clock means 2 is supplied with power from the battery when the main power is not supplied, it continues to operate even in the low power state (low power mode) (S3), and when the set designated time is reached, the power is supplied. An alarm signal is sent to the control means 1. Then, the power supply control means 1 turns on the main power supply switch 6 which was in the off state until then, restarts the supply of the main power supply, and thereby the control means 4 executes the restoration process (S4). The power supply control means 1 can operate even in the low power mode because the sub power supply is supplied. Then, the control means 4 performs time designation transmission (S5). That is, the control means 4 acquires from the control memory 11 the destination terminal number of the time-specified transmission, which is the current time when the designated time is almost the same time, makes a call to the destination, and is associated with the destination. The file number (corresponding when the image information is stored in the data memory 3)
The image information of the file number acquired from 11 is read from the data memory 3 and transmitted to the other party. As described above, since the sub power is supplied to the data memory 3 even in the low power mode, the image information is not lost.

The power supply control means 1 also exits the low power mode by the ON signal from the low power key 21. That is, when the power control means 1 recognizes the ON signal from the low power key 21 when not in the low power mode, it shifts to the low power mode, and when it recognizes the ON signal in the low power mode, it exits the low power mode. Is. Therefore, if the user wants to perform transmission or the like in the low power mode, the user may press the low power key 21 to forcibly return to the normal power mode (main power supply state). Further, the power supply control means 1 is N
Even when the CU 7 detects an incoming call from the line, it exits the low power mode by the signal from the NCU 7. In this case, the control means 4 performs the reception process after the restoration process. After the operation such as the time designated transmission is completed, the standby state (S2) is resumed, and the low power state (S3) is resumed. When the next designated time is set in the control memory 11 when the designated transmission is completed, the designated time is set in the clock means 2.

Although the specified time has been described above in the case of the time specified transmission, the specified time may be a specified time other than the time specified transmission such as the reception mode switching time or the heater preheating mode switching time. What is the reception mode switching above?
It is switching between facsimile mode and telephone mode,
When the set time is reached, if it is in the low power mode at that time, it is returned to the normal power mode to enable the control means 4 and the control means 4 switches the reception mode. Further, in the preheating mode switching, when the set time is reached, the control unit 4 similarly switches on / off the fixing heater of the recording unit 10.
Further, the designated time is not limited to the facsimile machine. For example, a personal computer can return from the low power mode to the normal power mode at a designated time and send an e-mail or the like.

[0016]

As described above, according to the present invention,
According to another aspect of the power supply control device of the present invention, the main power supply is stopped until the designated time when the main body executes the predetermined operation, and the main power supply is started when the designated time is reached. Therefore, power saving control can be performed in the information device that starts a predetermined operation at the specified time. In the facsimile apparatus according to the second aspect of the present invention, the main power supply can be stopped until the designated time to execute the time designated transmission is reached, and the main power supply can be started when the designated time is reached. Power saving control can be performed even when time-specified transmission is performed. In the power supply control device or the facsimile device according to claim 3, the next predetermined operation is not started even after the predetermined time A has passed from the end of the predetermined operation, and the time until the next designated time is the predetermined time B or more. In this case, since the supply of the main power is stopped again, the number of times the main power switch is turned on / off can be reduced and the reliability of the switch can be improved in addition to the above effect. In the facsimile apparatus according to the fourth aspect, the main power supply to the data memory can be stopped, so that the power saving effect can be further enhanced.
