Abstract

PURPOSE:To eliminate the waste of a power consumption by detecting the start and end for transmitting received data from a line to a G3 facsimile equipment by a detecting part, turning the power source of the G3 equipment ON corresponding to the start of the transmission to the G3 facsimile equipment, and turning the power source of the G3 equipment OFF corresponding to the end of the transmission. CONSTITUTION:When the G3 equipment 14 is not used for a long time, a facsimile interface equipment 12 is set in a waiting state to turn an inside switch 10 OFF, and when the interface equipment receives picture data from a line in the state, the data are successively stored in a picture data storing memory. When the transmission of the stored picture data to the G3 facsimile equipment is started after the completion of reception, a received data detecting part 9 detects the start of the data transmission, and turns the inside switch 10 ON by the detection signal, and a power source part 13 of the G3 equipment is supplied with a power from a power source 11 of the interface equipment, and turned into an operating state. When the interface equipment completes the transmission of the picture data, the detecting part 9 detects the completion, and turns the inside switch 10 OFF. Thus, the power consumption when the receiving operation is not executed, can be reduced.

Facsimile interface device f-G Receives image data from three machines and converts it into image data corresponding to black and white pixels,
The images are dimensionally encoded and sequentially stored in the image storage memory 2. When the transmission from the 03 machine is completed, the memorized data is
It is sent to the 15DN via the 5DN interface 7. In addition, when receiving from a G4 partner device, if you turn on the power of the G3 device and the interface device in advance, the interface device will sequentially store the image data of the other device in the image storage memory 2, and after the reception is completed. The stored data is output to the 03 machine.

Problems to be Solved by the Invention With such conventional facsimile interface devices, both the 03 machine and the interface device must be powered on in advance for both sending and receiving operations, which makes the operation complicated. ,Also,
Leaving it on all the time results in unnecessary power consumption.

The present invention solves the above problems and improves operability.
