Abstract

PURPOSE:To use a device in each scale factor by use of one in-mirror lens, by providing a guide rail in the proximity of 3 image forming parts of a variable reduction factor mechanism, so as to be parallel with a line for connecting each image forming part position, and supporting an arm which holds the in-mirror lens by its tip, by this guide rail so as to be freely rotatable. CONSTITUTION:On the base part of an arm 3, by which an in-mirror lens 4 is held, a bearing 2 is provided so as to be rotatable, also the bearing 2 is fitted into a guide rail 1 so as to be freely slidable but so as not to rotate, and on the lower side of the tip of the arm 3, three adjusting screws 5a-5c are provided in the lengthwise direction of the arm, and when an endless wire 7 connected to the base part of the arm 3 is moved intermittently by a prescribed distance, adjusting screws 5a-5c of the arm 3 contact with cams 6a-6c on a supporting plate 6, and as a result, the arm 3 moves to each size reduction factor position P1-P3, respectively, along the guide rod 1.
