ABSTRACT:
The apparatus comprises a light source, generally a laser diode, providing beam that is modulated by an input signal and is controlled for scanning, at a rate fixed by a clock, along a generatrix line of a photosensitive drum which is rotated by a motor; it further includes a memory for storing input data representing successive pixels of all lines in a page which were scanned for transmission, and a computer for determining the length to be reproduced of the transmitted document, and for determining the width, necessary to avoid truncating the infor mation contained in any of the scan lines, in the width direction. The computer calculates the minimum vertical reduction ratio Rv and the minimum horizontal reduction ratio Rh that should be adopted in order to enable the useful information to be reproduced in length and width and selects the smaller ratios. The frequency of the clock and the motor of the drum are controlled to achieve the smaller reduction ratio both in the horizontal direction and in the vertical direction.
