Abstract

An optical system of a reproducing apparatus having an exposure light source wherein the reflector of said exposure light source has a form of a curve of secondary degree and is adapted to be split into an upper half part and a lower half part at the non-reflecting surface of said reflector, said upper half part and lower half part being connected with a connecting member. The exposure device has a holding frame for holding an exposure optical system and guide members for movably guiding said holding frame. The guide members include an upper guide member disposed at the upper side of said holding frame and a lower guide member disposed at the lower side of said holding frame, said holding frame making a sliding contact with said lower guide member and contacting said upper frame member through an elastic member. On a lower position of said upper guide member is disposed an electrical collecting member.
