In an exposure device that projects light reflected from a document surface onto an arbitrary surface via a plurality of reflecting mirrors and lenses positioned between the reflecting mirrors, the plurality of reflecting mirrors are a reflector support member that is displaceable between a position where the reflector is held and a take-out position that allows the reflector to be taken out; and each vertex of a virtual triangle on the reflector mounting surface of the reflector support member. an elastic body that is placed at a position and has the habit of coming into contact with the back surface of the reflecting mirror and lifting the reflecting mirror from the above-mentioned mounting surface; and a member that is provided on a member facing the elastic body with the reflecting mirror in between. 1. An exposure apparatus comprising: a reflective surface regulating member that can come into contact with the reflective surface of the reflective mirror and sets the inclination angle of the reflective mirror due to lifting. 2. The exposure apparatus according to claim 1, wherein a convex portion extending toward the edge of the reflecting mirror is formed at a position corresponding to the edge of the reflecting mirror on the reflecting mirror support member. 3. The exposure apparatus according to claim 2, wherein the convex portion is made of a material that is harder than the main body of the reflecting mirror support member.
