Filter driving mechanism for image recording device

摘要

An image recording device applies light including image information from an original through a focusing optical system to a photosensitive member to record the image information on the photosensitive member. A filter driving mechanism in the image recording device includes at least two filter groups each including a plurality of equally spaced filters extending in a main scanning direction, the filter groups being disposed in a plurality of stages between the focusing optical system and the photosensitive member, and moving mechanisms for moving the filter groups back and forth in a direction substantially normal to the main scanning direction.
