ABSTRACT:
A table start position selecting mechanism for an electrophotographic copying machine of the type with a movable table comprises a unistructural lamp unit with a lamp and a primary mirror for initially reflecting light from a document on the table. A table start position detection switch is attached to a supporting plate which is independent of the lamp unit and adjustable with respect thereto in the direction of motion of the table. A positioning device such as a pin is affixed to the lamp unit at the center of its optical axis such that the switch-supporting plate can be easily and accurately positioned with respect to the lamp unit in the direction of motion of the table.
