Abstract

PURPOSE:To realize as document scanner being excellent in its vibration proofing effect, by attaching a damper of a mass (m) to a reciprocating moving member of an exposure optical system by a spring of a spring constant (k), so that it can move relatively against the moving member, and also, (m) and (k) satisfy a specific condition. CONSTITUTION:A plane mirror 2 is attached to a supporting body 2A, and brought to reciprocating motion along a guide rod 10 together with the supporting body 2A by a wire 20 fixed to the end part of the supporting body 2A. To this moving member, a damper 25 of a mass (m) is attached by a spring 24 of a spring constant(k), so that the damper 25 can move relatively against the plane mirror 2 in the moving direction of the plane mirror 2. Also, when a mass of the moving member and a spring constant of elastic force working on the moving member are denoted as M and K, respectively, (m) and (k) are determined so as to satisfy a condition of (k/m) (K/M). In such a way, a resonance frequency of the moving member is shifted from its original frequency, the phase allowance increases, and the control system is stabilized.
