Abstract
In an electrophotographic copying machine of a type in which an original table is fixed, a wire is stretched over pulleys provided on two movable members so that a slit for scanning an orignal and a set of reflecting mirrors for reflecting light from the slit towards a lens may be moved at a ratio of 2:1. According to this invention, an endless wire having the opposite ends of the wire connected is used, and an adjusting screw capable of adjusting a spacing between both the movable members by turning the screw is provided at the connected portion, and focussing can be made by turning the adjusting screw. If this adjusting screw is made to expose to the outside of the copying machine body, focussing can be made from outside.
