ABSTRACT:
A facsimile apparatus in which the transmitted picture image is partially or totally enlarged at the receiving unit thereof. If the recorded image is to be smaller than the original image, a first switch is closed at the transmitter unit and information bits are periodically removed from both the main scanning and subscanning portions of the transmitted picture signal. If the recorded image is to be larger than the original image, a second switch is closed at the transmitter unit and expansion bits are periodically inserted in the subscanning portion of the transmitted picture signal. In the latter case, a third switch is closed in the receiver unit and expansion bits are inserted into the main scanning portion of the signal. Alternatively, the transmitter can send an instruction signal, in which case the receiver inserts expansion bits in both the main and subscanning directions.
