ABSTRACT:
A supporting apparatus for optical unit having an optical unit to expose an original set on a contact glass, a reciprocatingly movable supporting frame body equipped with the optical unit, a sliding member provided on both ends of the supporting frame body, and an eccentric cam mechanism provided on one end of the supporting frame body to vertically adjust one of the sliding member. By operating the eccentric cam mechanism, one end of the supporting frame body can be adjusted to a desired height so as to enable to adjust horizontality of the optical unit mounted on the supporting frame body. Furthermore, because a large gap is provided between a pair of sliding members provided on one end of each supporting frame body and the ends of the two supporting frame bodies where the sliding members are mounted are mutually disposed at reverse side, both supporting frame bodies can be caused to come as close at their home positions as possible.
