距離の略二倍となる位置関係を、上記光学レンズ
系とベアリングに常にとらせるように構成されて
いることを特徴とする、ＬＥＤプリントヘツド。[Claims for Utility Model Registration] A large number of LED elements arranged in a row on a substrate,
An LE comprising an optical lens system that focuses light from the LED element onto a photoconductor, and a bearing that comes into contact with the photoconductor to position the photoconductor.
D print head, wherein a pair of position adjustment mechanisms are provided at both ends of the substrate to support the end portions of the optical lens system in a position-adjustable manner above the bearings; The adjustment mechanism adjusts the optical lens so that the distance between the upper surface of the positioning bearing and the light emitting surface of the LED element is approximately twice the distance between the center of the optical lens system and the light emitting surface. An LED print head characterized in that it is configured such that the system and bearings are always engaged.
