Title: Zoom variable power copying machine
Inventor: SHINADA MASAYUKI
IPC: G03B27/34
Filed: 1985-01-28
Abstract: PURPOSE:To correct out of focus at any magnification at the time of variable power by constituting a guide member of a single member and setting the shape of a cam contour line for engaging with the roller of a lens positioning cam so that the change of a distance from the center of a cam rotation can be larger as a machine becomes farther from the engaging point at the time of equimultiple. CONSTITUTION:The guide member 10 is constituted of a single member whose guide surface forms one straight line. If the cam shape of the lens positioning cam 8 is of a straight line, the correction quantity of a lens moving amount is substantially shifted from the proper quantity. In order to approximate the shifting to the proper quantity, the shape of the cam 8 is dot-symmetric so that the change of the distance from the cam rotation center 16 can be larger as the machine becomes farther from the engaging point of the roller 7 at the time of equimultiple. The focal length of the lens used by each copying machine is measured, and the guide member 10 is fixed by tilting it at the predetermined angle with respect to the variance of the focal length of the lens, whereby the same amount of correction can be attained at the sides of reduction and enlargement.
