装置。[Claims for Utility Model Registration] A pair of guide members arranged parallel to each other,
A mirror movement frame that is slidably attached to the pair of guide members and holds the mirror; a drive motor that slides the mirror movement frame back and forth to perform image reading scanning and return scanning; and a drive motor that drives the drive motor. A drive pulley that transmits force to the mirror moving frame is provided, and the drive pulley is provided with a cylindrical hollow part coaxially with the rotation axis of the drive pulley.Furthermore, in this hollow part, the moment of inertia of the drive pulley is absorbed during scanning by reading the image of the mirror moving frame. An exposure scanning device sealed with a non-Newtonian viscoelastic liquid capable of increasing the moment of inertia of a drive pulley during return scanning of a mirror moving frame.
