    摘要： The invention provides an optical write linehead comprising a plurality of light emitter devices in rows located in association with each of a plurality positive lenses lined up in array form and designed such that even when the surface of the linehead with light emitter devices lined up on it and the write surface thereof fluctuate in the optical axis direction, there is no variation from misalignments of light-emission dots. The linehead comprises a light emitter array 1 including a plurality of light emitter blocks 4 located at least in the main scan direction at intervals. Each light emitter block 4 includes at least one row of a plurality of light emitter devices lined up in array form in the main scan direction. One each positive lens system 5 is located on the exit side of the light emitter array 1 and in line with each light emitting block 4. A write surface 41 is located on the imaging side of the lens array. Each positive lens system 5 forming a part of the lens array comprises a telephoto optical system having confocally located two lens groups L1 and L2 with an aperture stop 30 located at the confocal plane of the telephoto optical system.

    摘要： A line head (101) includes: a positive lens system having two lenses (L1,L2) with positive refractive power; a lens array (61,62) in which a plurality of the positive lens systems are arrayed in a first direction; a light emitter array (1) in which a plurality of light-emitting elements (2) are arrayed on an object side of the lens array so as to correspond to the one positive lens system; and an aperture plate (30) that forms an aperture diaphragm at the position of an object-side focal point of the positive lens system. An object-side surface of an object-side lens of the positive lens system is positioned close to the object-side focal point.
