Abstract

PURPOSE: To achieve simple and easy manupulation and enhance the working efficiency, by providing a control device for setting the magnification and detection part of longer and shorter side lengths of both original and paper.
CONSTITUTION: In order to detect the length of the longer and shorte sides of an original 4 placed on a contact glass 2, a member is provided, for instance, on the original 4 to read by fitting cursors 23, 24 from the positions thereof. In order to detect the length of longer and shorter sides of a paper 14, a member is provided, for instance, on a cassette 12 to read by setting specified mark when installing. In addition is furnished a control device 27 which sets the magnification by means of zoom lens 7 by receiving outputs from the detecting members for said original 4 and paper 14. By thus constituting, without requesting the operator to calculate the magnification and set, simply by manipulating the button, the original used in longer side direction or shorter side direction may be copied easily under the specified magnification by aligning in one direction, so that the working efficiency may be enhanced.
