In addition, when the charging / discharging battery for supplying the operation power of the control unit performing the control operation of each device is exhausted, the control unit controls the switching unit to supply power from the outside to be charged, and after fully charged By controlling the switching off, charging no longer occurs.

Therefore, since the power is not supplied when the facsimile device is not used, unnecessary power consumption can be prevented.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing an internal configuration of a facsimile apparatus having a power saving function according to an embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 2, reference numeral 11 denotes a power supply unit for power supply, 12 denotes a switching unit for turning on or off the power supply from the outside to the power supply unit 11 according to a predetermined control signal, and 13 denotes the network control device 8. It is a ring signal detector for detecting a ring signal received through.

In addition, the reference numeral 14 denotes a key input from the keypad 9, or when a ring signal is detected through the ring signal detection unit 13, the switching unit 12 applies a predetermined control signal to the switching unit 12. Control unit to turn on.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG. 3.

Normally, the switching unit 12 is in an off state, and in a state in which power supply from the outside is stopped, the control unit 14 receives a key input and a document insertion detection unit 1d of the keypad 9 by power supplied from a telephone line. The operation of detecting the insertion of a will be executed.

Then, when the user who wants to send the original inserts the original, the control unit 14 detects the insertion of the original through the original insertion detecting unit 1d (step ST1), and then the switching unit 12, for example, a high level. Control signal is sent (ST2 step).

Accordingly, the switching unit 12 is turned on by the high level signal received from the control unit 14 so that power from the outside is applied to the power supply unit 11.

Accordingly, the reading unit 1 is in a state in which it can operate by receiving power from the power source unit 11.

Then, when dialing is performed by the user so that the other side facsimile apparatus is connected to the call path and a start key (not shown) is input (step ST3), the control unit 14 controls the light source element 1a of the reading unit 1. (ON) and at the same time drive control of the CIS (1b) through the CIS controller (1c) to perform the image reading operation (step ST4).

Accordingly, the on-driven light source element 1a shines light on the original surface, and the CIS 1b signals the light reflected from the original surface by one scan line, which is decomposed by the scanning. The pixel information of the image is converted into binary data of 0 and 1 and stored in the data storage unit 5 in units of one scan line.

Subsequently, the controller 14 reads the pixel data stored in the data storage unit 5 in a predetermined unit, converts the pixel data stored in the data storage unit 5 into analog signals for trunk line transmission through the modulation / demodulation unit 7, and then executes the network control device ( 8) to the other fax machine (ST5 step).

On the other hand, when data transmission to the counterfeit facsimile apparatus is completed through the network control device 8 (step ST6), the control unit 14 switches the line and transmits a low level control signal to the switching unit 12, for example. Will be sent (ST7 step).

Therefore, the switching unit 12 is turned off by the low level control signal applied from the control unit 14, and the power supply from the outside is cut off.

That is, according to the first embodiment, since power consumption does not occur due to the operation of the reading unit 1 in accordance with the off state of the switching unit 12, power can be saved.

FIG. 4 is a block diagram showing the configuration of a facsimile device having a power saving function according to the second embodiment of the present invention. The same reference numerals are assigned to the same parts as those of FIGS. An embodiment will be described with reference to the described operation flowchart.

When the switching unit 12 is turned off, when a ring signal is received from the other side facsimile apparatus through the network control device 8 and the ring signal is detected through the ring signal detection unit 13 (step ST11), The control unit 14 transmits, for example, a high level control signal to the switching unit 12 (step ST12).

Accordingly, the switching unit 12 receiving the high level signal from the control unit 14 is turned on so that power from the outside is supplied through the power supply unit 11 through the facsimile apparatus, thereby printing the printing unit ( 2) becomes an operable state.

In addition, the display unit 10 is operated by being supplied with power to indicate that there is a current data reception.

Subsequently, when data is received from the other party's facsimile apparatus (step ST13), the received data is demodulated through the demodulation unit 7 and applied to the control unit 14.

The control unit 14 stores the received data in the data storage unit 5 and transmits the data to the printing unit 2 (step ST14).

In addition, the pulse generating unit 3 generates a pulse corresponding to the image data and applies it to the TPH 2c, and drives and controls the motor driving unit 2b to move the motor 2a to roll the recording paper. The printing operation is performed by transferring the.

On the other hand, when the reception of the data is finished (step ST16), the control unit 14 switches the line through the network control device 8 and transmits a low level control signal to the switching unit 12, for example. (ST17 step).

Therefore, the switching unit 12 is turned off by the low level signal applied from the control unit 14, thereby stopping the supply of power applied from the outside.

That is, according to the second embodiment, power consumption is not generated due to the operation of the printing unit 2 according to the off state of the switching unit 12, thereby saving power.

6 is a block diagram showing the configuration of a facsimile device having a power saving function according to a third embodiment of the present invention, and the same reference numerals are assigned to the same parts as those of FIGS. 1, 2, and 4; The detailed description is omitted.

The facsimile apparatus according to the third embodiment of the present invention is configured to communicate with the facsimile apparatus using a telephone line separate from the electric line, but the general function of the facsimile apparatus is possible by receiving operating power from an independent power source. If possible, it is combined with external power and wire.

On the other hand, when the power supply is cut off from the outside, the control operation of the control unit 14 is stopped.

Therefore, the power supply from the outside is compensated for the defect that the control operation of the control unit 14 is stopped to provide a battery BAT for charging and discharging therein. Thus, when the external power source is cut off, the operation power is supplied from the battery BAT to control the operation of the facsimile apparatus for a predetermined time.

However, since the charging / discharging battery BAT has a limited charging capacity, it is impossible for the internal battery BAT to continuously supply the operating power of the facsimile apparatus when power supply from the outside is stopped.

Therefore, the controller 14 can detect the consumption state of the voltage charged or discharged in the battery BAT for charging and discharging.

That is, in the device according to the third embodiment of the present invention, a battery BAT for charging and discharging is installed between the power supply 11 and the ground, and a diode for preventing reverse current flow on the power supply path to the battery BAT. D1 is installed and connected to the controller 14 such that power of the battery BAT is supplied to the controller 14.

In addition, the A / D converter 15 is installed on the power supply path from the battery BAT to the controller 14 to detect the state of the charge potential of the battery BAT, so that the voltage signal is converted into a digital signal. It is applied to the control part 14.

Therefore, when the voltage of the battery for exclusive use of the charging / discharging BAT is consumed more than a certain level, for example, a data signal corresponding to 2.2 V, which is the lowest potential level, is applied from the A / D converter 15, the controller 14 switches the switching. By controlling the unit 12 on, power is supplied from the outside.

Therefore, power is supplied from the outside, and the power is charged to the charging / discharging battery BAT through the power supply unit 11.

In addition, when the battery BAT is sufficiently charged so that a data signal corresponding to a predetermined voltage, for example, 5V, is applied from the A / D converter 15, the controller 14 controls the switching unit 12. By controlling the control off, the power supply from the outside is cut off so that no further charging occurs.

That is, when the facsimile apparatus according to the third embodiment of the present invention is operated through the battery for charging and discharging, when the power is exhausted and the voltage of the battery BAT is detected to be lower than or equal to the predetermined level, the controller 14 Since the power is supplied from the outside by controlling the switching unit 12 on, the power is charged to the charging / discharging battery BAT through the power supply unit 11.

In addition, when it is detected that the battery BAT is sufficiently charged to become a constant voltage, the controller 14 controls the switching unit 12 to be turned off to cut off the power supply from the outside to the battery BAT for charging and discharging. Charging stops.

That is, according to the above embodiments, the control unit 14 controls the switching unit 14 only when the insertion of the original is detected through the original insertion detecting unit 1d or when the ring signal is detected through the ring signal detecting unit 13. Since power is supplied from the outside by turning on 12), power consumption due to operations of the reading unit 1 or the printing unit 2 which consumes a lot of power can be reduced.

In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the technical scope of the present invention.

As described above, according to the present invention, since the power is supplied only when the facsimile apparatus is used, a facsimile apparatus having a power saving function capable of reducing unnecessary power consumption can be realized.
