Claims

[Scope of Claim for Utility Model Registration] A document placed on a contact glass surface for document placement is irradiated with illumination light from a lamp, and an image of the irradiated light of the document is exposed onto a photoreceptor through a plurality of mirrors. The exposure optical system of a copying machine is a moving optical system in which the lamp and each mirror are reciprocated along the contact glass surface in synchronization with the rotation or movement of the photoreceptor using wires and pulleys, the moving optical system comprising: A shock absorbing device for a moving optical system, characterized in that a wire that functions when the system returns is connected to a moving body of the optical system, or a suitable position of the wire is connected by a buffer member.
