Abstract

PURPOSE:To reduce the power consumed by the equipment in the standby state. CONSTITUTION:When a call comes from a communication network 1 to a facsimile equipment, an incoming call detection section 2 operated from power by the communication network 1 detects the incoming call and outputs an incoming call detection signal 6 to a power supply section 5. A power supply device 5 receiving the incoming call detection signal 6 starts supplying power 9 to a picture data reception section 3 and a picture data output section 4. When the supply of the power 9 is started, the picture data section 3 outputs a picture data 7 to the picture data output section 4. The picture data output section 4 prints out all picture data 7 received by the picture data reception section 3 from the communication network 1 onto recording paper and when print-out is finished, a picture data output end signal 8 to the power supply section 5. The power supply section 5 receiving the picture data output end signal 8 stops the power supply to the picture data reception section 3 and the picture data output section 4.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine whose power supply is controlled.

0002

2. Description of the Related Art In a conventional facsimile machine, power is kept supplied to the main parts of the machine both in a state in which information is received from a network and in a state in which a request to send an outgoing request to the network is waited for.

0003

[Problems to be Solved by the Invention] In the above-mentioned conventional facsimile communication device, power is always supplied to the main parts of the device, and when the device is in the state of waiting for information to arrive from the network or the state of waiting for an outgoing request to the network, The disadvantage is that it wastes power.

0004

[Means for Solving the Problems] A facsimile device according to a first aspect of the present invention operates on line power supplied from the network side when power is not supplied to the device, detects an incoming call from a communication network, and detects an incoming call. The apparatus includes means for outputting as a detection signal, and means for supplying the power to the main part of the apparatus based on the incoming call detection signal, detecting completion of reception of image data, and stopping supply of the power.

The facsimile device according to the second aspect of the present invention operates on the line power supplied from the network side when power is not supplied to the device, detects a transmission request to the communication network, and outputs it as a transmission request detection signal. and means for supplying the power to the main part of the apparatus according to the transmission request detection signal, detecting the end of transmission of image data, and stopping the supply of the power.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a first embodiment of the present invention.

When the facsimile machine receives an incoming call from the communication network 1, the incoming call detection unit 2, which operates using power from the communication network 1, detects the incoming call and outputs an incoming call detection signal 6 to the power supply unit 5. The power supply mechanism 5 to which the incoming call detection signal 6 is input starts supplying power 9 to the image data receiving section 3 and the image data outputting section 4. When the supply of power 9 is started, the image data receiving section 3 outputs the image data 7 to the image data output section 4. The image data output unit 4 prints all the image data 7 received by the image data reception unit 3 from the communication network 1 on recording paper, and when the print output is finished, outputs an image data output end signal 8 to the power supply unit 5. do. The power supply section 5 to which the image data output end signal 8 has been input stops supplying power to the image data reception section 3 and the image data output section 4.

FIG. 2 is a block diagram of a second embodiment of the invention. When there is a call request to the facsimile machine, the call request detection unit 13 detects the call request and sends a call request detection signal 1.
6 is output to the power supply section 15. Outgoing request detection signal 16
The power supply section 15 to which the
Then, the supply of power 19 to the image data output section 14 is started. When the power supply 19 starts, the image data input unit 14
outputs the image data 17 to the image data transmitter 13. The image data transmitting section 13 transmits all the image data 17 inputted by the image data input section 14 to the communication network 11, and outputs an image data transmission end signal 18 to the power supply section 15 when the transmission is completed. The power supply section 15 to which the image data transmission end signal 8 has been input stops supplying the power supply 19 to the image data transmission section 13 and the image data input section 14 .

[0009]

[Effects of the Invention] As explained above, the present invention operates using power from a telephone line, detects an incoming call or an outgoing call, and
By providing a means for supplying power to the main parts of the device, power can be supplied to the device when an incoming call or outgoing request is received, reducing the power consumed by the device in standby mode. There are effects that can be reduced.
