ABSTRACT:
Facsimile equipment includes an image scanner for reading image information from an transmit original, a coder for coding the image signal to produce image data, a modulator/demodulator coupled to the coder and to a line via a network control unit, a decoder for decoding image data transmitted over the line to reproduce an image signal, a printer for printing an image on a recording paper in response to the reproduced image signal, and a dialer coupled to the network control unit for producing dial pulses corresponding to a dialing number. The facsimile equipment further includes a keyboard, a memory, and a card reader. The keyboard includes ten keys for entering dial numbers for usual dialing operation and memory keys for reading dial numbers stored in the memory for dialing by a single key operation. The memory stores dial numbers in the form of a table accessed by the types of the card and the memory key. The card reader reads from a card loaded into the facsimile equipment information representing the type of the card. Dialing number is read out from the table in accordance with the memory key operated and the type of the card. The dialer produced dial pulses in response to the read dialing information.
