Mechanism for adjusting the starting position of sliding table of an electrophotographic copying machine

摘要

This invention relates to an electrophotographic copying machine of a type having a table which moves along a given direction and a source unit of a unitized structure which includes a lamp and a mirror for initially reflecting the reflected light from a document to be copied such that the position of the source unit can be adjusted at the time of its assembly. The copying machine according to the present invention includes a detector for detecting the starting position of the slidably movable table and this detector is attached to a plate of which the position is adjustable along the direction of motion of the table independently of the source unit whereby the problems associated with fluctuations in the start-up distance traveled by the table before acquiring a steady speed can be eliminated.
