真記録装置の露光機構。[Claims for Utility Model Registration] (1) A housing rotatably housing a photoreceptor having flanges at both ends is installed between a pair of side frames, has an LED array as a light source, and this L
An optical print head having a fixed optical lens for focusing the light beam from the ED array on the surface of the photoreceptor is attached between the side frames via a support member, and the photoreceptor is attached to the side of the side frame together with the housing. In an exposure mechanism of an electrophotographic recording device that is more removable, the diameter of the flange is larger than the diameter of the photoreceptor, and the optical print head is supported by the support member so as to be movable in the radial direction of the photoreceptor. At the same time, a biasing means for biasing the optical print head toward the photoconductor is provided, and the biasing force of the biasing device abuts the flange to hold the LED array parallel to the surface of the photoconductor at a constant height. An exposure mechanism for an electrophotographic recording device, characterized in that a follower roller is rotatably attached to an optical print head. (2) Claim (1) characterized in that at least one end face corner of the flange and the follower roller is tapered or rounded with a predetermined curvature.
Exposure mechanism of the electrophotographic recording device described. (3) The diameter of the follower roller on the front side in the direction in which the housing is pulled out is made smaller than the diameter of the follower roller on the rear side, and the housing is made so that the LED array of the optical print head can be kept parallel to the axial center line of the photoreceptor. 2. The exposure mechanism for an electrophotographic recording apparatus according to claim 1, wherein the diameter of the flange corresponding to the follower roller on the front side in the drawing direction of the image forming apparatus is larger than the diameter of the flange corresponding to the follower roller on the rear side.
