Abstract

PURPOSE:To achieve variable power copying automatically by determining the variable power ratio in a control device on the basis of paper and turning the image, by providing a device to detect the length of each side of the original on an original platen and the length of each side of paper, and a rotating member to convert the image 90 deg. around the optical axis. CONSTITUTION:The original 4 on a contact glass 2 is exposed with an exposure lamp 5, and the image is introduced onto a photosensitive belt 12 by way of first mirror 6, zoom lens 7, trapezoidal prism 8, second mirror 9, third mirror 10, and a latent image is fofmed. The trapezoidal prism 8 can rotate the exit image 90 deg. around an optical axis 25 with respect to the incident image by means of image direction indication dial 20. The length of each side of the original 4 on the glass 2 is measured by cursors 28, 29, and the length of each side of paper 16 is measured, for example, in a cassette 14. A control device 32 determines the magnification of zoom lens 7 according to the size of the original 4, on the basis of the size of the paper 16, and the trapezoidal prism 8 is rotated with respect to the indicated position of the image direction indication dial 20, so that variable power copying may be performed automatically.
