Abstract:
A facsimile apparatus having a wireless call capability, able to reduce undesirable electromagnetic interference in aural signals during wireless telephone calls, thereby improving wireless telephone call quality and increasing wireless telephone call distance, comprising:a first control unit controlling a facsimile apparatus, outputting a first power control signal in response to image signals, outputting a second power control signal in response to aural signals, receiving a sensing signal, and receiving a command signal;a transceiver unit coupled to said first control unit, transmitting and receiving aural and image signals via airwaves;a line interface unit coupled to said first control unit and said transceiver unit, receiving and transmitting aural and image signals from and to a central office exchange via a cable, and receiving and transmitting aural and image signals from and to said transceiver unit;a power supply unit outputting a first power to said first control unit and outputting a second power;a sensor coupled to said first control unit, sensing an original document having a surface containing image data, receiving the first power from said power supply unit, and transmitting the sensing signal to said first control unit in response to the sensing of the original document;an operating panel coupled to said first control unit comprising a plurality of keys for entering numeric digits and commands, receiving the first power from said power supply unit, and transmitting the command signal to said first control unit;a switch unit receiving the second power from said power supply unit, receiving the first and second power control signals from said first control unit, outputting the second power in response to the first power control signal corresponding to image signals transmitted and received, and stopping output of the second power in response to the second power control signal corresponding to aural signals transmitted and received;a modulator/demodulator unit coupled to said line interface unit, modulating and demodulating image signals, selectively receiving the second power from said switch unit according to the first and second power control signals, and receiving and transmitting image signals;a scanner reading image data from the original document, transmitting image signals corresponding to read image data, and selectively receiving the second power from said switch unit according to the first and second power control signals;a memory storing image signals received from said scanner, and selectively receiving the second power from said switch unit according to the first and second power control signals;a printer receiving image signals, recording image data on a recordable medium corresponding to received image signals, and selectively receiving the second power from said switch unit according to the first and second power control signals; anda second control unit coupled to said first control unit, scanner, memory, and printer, selectively receiving the second power from said switch unit according to the first and second power control signals, and controlling said scanner, memory, and printer.
