BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having an automatic reception function.

[0002]

2. Description of the Related Art Conventionally, in a device having a standby state such as a facsimile device, a switching power supply or the like has been used as its power supply. The power is always on during standby or during operation. In addition, the primary side of the main power source is also directly controlled by a calling signal from a telephone line, etc., and power saving is achieved. In addition to the main power supply, there is also a device that has a sub power supply for scumbai separately. In this type of device, only the sub power supply is activated during standby, and the main power supply is activated only during operation. As a result, low power consumption is achieved.

Furthermore, a completely new system has been proposed, which is also intended to reduce power consumption during standby (JP-A-6-311269). In this system, the main power supply control unit controls the start and stop of the main power supply (switching power supply), and the secondary battery supplies power to this main power supply control unit during standby and the main power supply during operation. so,
In the standby system, the main power supply is stopped, only the main power supply control unit operates (standby), and during operation, the main power supply rises while the control signal from the main power supply control unit is applied to the main power supply. As a result, the power consumption can be further reduced as compared with the conventional one.

In the former conventional facsimile apparatus, the power source (sub power source) is always on. Therefore, for example, when the system goes out of control, the reset switch is forcibly operated to reliably restore normal operation. You can

[0005]

However, the latter newly proposed system of the conventional example has the following problems. When an attempt is made to initialize the main power supply control unit, the initialization signal is being applied (normal level is the R of the microcomputer which is the center of the main power supply control unit).
Since the main power source control unit cannot control the main power source (while the voltage is applied to the ESET port), the main power source stops operating. Therefore, when trying to initialize the main power supply control unit with a forced reset switch or the like, the main power supply control unit supplies power only from the secondary battery while continuing to apply the initialization signal by turning on the reset switch. If the reset switch is turned on for a long time, the secondary battery may be completely discharged due to leakage current due to a current limiting resistor around the reset switch. Therefore, the main power supply control unit cannot be initialized. In this case, the main power supply cannot be turned on, and it becomes impossible to restore the device to the operating state.

An object of the present invention is to provide a facsimile apparatus having an automatic receiving function, which consumes no electric power all day due to the automatic receiving function and can greatly reduce the loss of power amount.

FIG. 5, FIG. 6, FIG. 7, and FIG. 8 are flowcharts showing the operation of this embodiment, and the operation will be described with reference to these drawings.

FIG. 5 is an operation flow in the FAX standby state. In FIG. 5, when the AC input is started (step S501), the main power supply 16 first rises (step S502) to initialize the microcomputer 17 and ( Step S503,) CPU2 is initialized (step S504), and at the same time, charging of the secondary battery 19 is started (step S505). When the initialization of the microcomputer 17 is completed, the FAX goes into a standby state. And at this time, OUT5 of the microcomputer 17
Is at the Low level, the output of the AND gate 62, that is, the PS signal is at the Low level, and the photocoupler 45 is turned on via the transistor 46, so that the main power supply 16 continues to operate and the secondary side Is supplying power to. The secondary battery 19 continues to be charged while the standby state continues.

If the charging is completed (step S5)
06), that is, when the output of the voltage detection circuit 28 becomes High level or when the timer built in the microcomputer 17 has passed one hour, the following operation is performed. In the former case, the IN13 of the microcomputer 17 becomes High level, and accordingly, the microcomputer 17 sets OUT5 to High.
Set to h level. Then, since the AND gate 62 outputs the high level, the PS signal becomes the high level and the main power supply 16 stops its operation (step S507).
Along with this, RE of the voltage detection circuit 60 becomes Low level, and the CPU 2 is reset (step S508).
Then, the power supply by only the secondary battery 19 and the solar battery 23 is started (step S509). In the latter case,

The photocouplers 33 are turned on, and this ON signal is input to the microcomputer 17, and accordingly, the microcomputer 17 sets OUT5 to the Low level. Then AND gate 6
2 outputs the low level, and the PS signal becomes the low level, so that the photocoupler 45 is turned on. Photo coupler 4
When 5 is turned on, the IC 44 oscillates the primary side via the FET 43, power is supplied to the secondary side, and the main power supply 16 starts up (step S707). When the call signal CI is detected (step S703), the photocoupler 32
Is turned on, an ON signal is input to the microcomputer 17, and accordingly, the microcomputer 17 sets OUT5 to the Low level. Then, the AND gate 62 outputs Low level,

9). While the main power supply 16 is on, the secondary battery 19
Is always charged. Then, this information is sent to the CPU 2 through the serial interface, after which the CPU 2 mainly controls the operation of the facsimile apparatus 1.

If the hooking button is pressed (step S711) or the handset is off-hook (step S702), a call is made to the other FAX (step S710) and the line is captured (step S711).
Normal facsimile reception is performed. When the calling signal CI is detected (step S), the NCU 10 captures the line (step S711), and the facsimile reception is performed by the automatic reception (step S712). When reception ends (step S713) and the line is disconnected (step S71)

T5 is set to High level. Then AND gate 62
Outputs high level, the PS signal is high
The main power supply 16 stops operating at the level. And C
PU2 is reset and charging of the secondary battery 19 is terminated. Then, the FAX standby state is set, and the process returns to A in FIG.

In FIG. 7, * indicates the main system (CP
This is control by U2).

FIG. 8 is a flow chart showing the operation when the microcomputer 17 is forcibly reset. In the figure, when the reset switch 63 is turned on (step S
801), RESET of the microcomputer 17 becomes Low level, and one input of the AND gate 62 becomes Low level, so the AND gate 62 outputs Low level (step S804), which causes the PS signal to become Low.

Becomes an operating state (step S803). When the reset switch 63 is turned off (step S804), RESET of the microcomputer 17 becomes High level, and the process returns to B in FIG. As a result, while the reset switch 63 is turned on, the main power source 16 is always in the operating state and supplies electric power regardless of the control of the microcomputer 17, so that even if the reset switch 63 is kept on for a long time, the resistance 6
The secondary battery 19 will not be completely discharged due to the power consumption of the reset switch 63.
When is turned off, the microcomputer 17 is surely initialized. At this time, the CPU 2 is also surely initialized. Although the case where the reset switch is forcibly turned on has been described in the present embodiment, the voltage detection circuit 1 at the time of starting the AC input is described.
Similarly, when the microcomputer 17 is reset by the
Is activated, the microcomputer 17 is surely initialized. In the above, while the main power supply 16 is on, the secondary battery 19 is charged at the same time. As a result, the number of times the main power supply 16 is started up only for charging the secondary battery 19 is reduced, and extra power consumption can be prevented.

A main power supply 16 for supplying power to the main power supply control unit 15,
Since the secondary battery 19 and, if necessary, the solar battery 23 are provided to control each power supply, as described above, the power consumption during standby can be made approximately 0 W.

Therefore, the automatic reception function does not consume power all day long, the loss of power amount is small, and the generation of radiation noise is prevented. In addition, since the primary side of the main power supply 16 is not directly controlled by a plurality of means, there is no restriction on safety standards, and it can be easily implemented.

By providing the AND gate 62,
While the control by the microcomputer 17 is impossible, that is, the microcomputer 1
While RESET of 7 is at the low level, the main power supply 16 is always in the operating state to supply electric power, so that even if the reset switch 63 is kept ON for a long time, the secondary battery 19 is discharged due to power consumption by the resistor 64 and the like. It will not run out, then the reset switch 63 will be OFF
When it is done, the microcomputer 17 is surely initialized.

When the microcomputer 17 is initialized CPU2
Even if either or both of the microcomputer 17 and the CPU 2 run out of control, they can be easily returned to normal operation by turning the reset switch 63 on and off, for example.
