Abstract

PURPOSE:To simplify the constitution of the titled device and to reduce the production cost by setting up a position in the optical axis direction of a lens in accordance with its copying magnification. CONSTITUTION:When a motor 29 is rotated in the counterclockwise direction and a lens mount 24 is moved in the right to execute contracted copying, a winding pulley 30 is moved in the right together with the lens mount 24 and a cam follower arm 31 is contacted with a cam 36 and oscillated. The 1st mirror 9 is moved in the left on the basis of the sum of the drawn length of a wire 34 due to the movement of the winding pulley 30 and the winding length M of the wire 34 due to the rotation of the winding pulley united with an arm 31 and the lens 11 and the 1st mirror 9 are driven to a position corresponding to the copying magnification. Namely, when the lens mount 24 is moved by (1-m)f through the rotation of the motor 29 so as to correspond to the copying magnification, the 1st mirror 9 is moved to the position corresponding to the copying magnification (m) by following the movement of the lens mount 24, so that copying can be attained at a required copying magnification (m).

In addition, when the magnification is mσ, the distance from the document 7 to the lens 11 is a rrt, and the distance v from the lens 11 to the photoreceptor 12 is b.
rrt means α7π=□f1...(8) brn=(m+l)f''(9) Photoreceptor 1
While keeping the lens 2 fixed, move the lens 11 and the first mirror 9, and change the distances am and am.

In this case, the distance ix required to move the first mirror 9 is shown. The attachment is due to the rotation of the pulley I, and the rotation is the sum of the amount M, which is equal to the right-hand side of equation (2), and the lens mount is set to 2/1 (2/1) to match the copying magnification mFc by the rotation of the motor. 1-m) When moved fw, the second lens 9 adapts to the copying magnification m, and the lens mount 24 is placed at the r:f;L position (one movement following the IJ movement).
Copying can be performed at a variable copying magnification nL'.On the other hand, if you want to enlarge the image 1c, move the lens mount 24 to the left as shown in FIG.
For the same reason as mentioned above, the required σ) enlarged copying becomes possible.

In the embodiment shown in FIGS. 1 to 6, by moving the platen glass 3, the platen cover 6, and the original 7 to each other, the image of the original 7c/ can be scanned. Since the first mirror 9 and lens 11 are moved correspondingly, when the fold copying magnification is changed, the copying start position of the original 7 is shifted to the left corner, as shown in FIG. As shown in FIG.
A cam 36 is formed on the cam 5 so that the movement of the original 7 can be adjusted by half of the movement of the original 7. It is possible to fix the copy start position.

In a variable reproduction magnification type reversing machine that performs the optical path length from the original surface to the exposure surface of the photoreceptor without changing the focal length and the reproduction magnification VC, the reproduction magnification variable type reversing machine is capable of changing the optical path length from the document surface to the exposed surface of the photoreceptor without changing the focal length. A lens position adjusting means that can change its axial position; a cam lower rotatably supported on the lens supporting means; and a pulley connected to the cam lower. A flexible connecting member having one end bound and the other end bound to a mirror near the document surface;
) The optical path length necessary to form an image on the image sensor 9-body exposure surface VC is formed in a shape that allows the original surface to be changed depending on the optical path length required to form an image. Copying machine C/ with a fixed cam that swings and guides and has yxQt8 features.
J Copying magnification variable device.
