ABSTRACT:
There is disclosed a system of a facsimile apparatus and a card-shaped calculator as a portable device to be helped by each user. The telephone number information and other information, which have conventionally registered in the facsimile unit, are stored in the card, which transmits such information to the facsimile unit when the card is set on the facsimile. The transfer of the information between the card and the facsimile unit is conveniently done by photocouplers. The system disperses the information required in the facsimile unit to the individual cards, thereby simplifying the structure and the operation of the facsimile unit. Also the card may be coupled with another facsimile unit so that the card owner can immediately use the registered telephone number information on any facsimile unit.
