Title:
LINEAR BEAM CONDENSING DEVICE, FIXATION DEVICE, AND IMAGE FORMATION DEVICE
Document Type and Number:
Japanese Patent JP2017227835
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear beam condensing device, a fixation device, and an image formation device which can reduce the manufacturing cost in a case where power-up is achieved with the number of lasers.SOLUTION: A linear beam condensing device includes a plane emission laser unit, a first optical element group, and second optical element group 63. The first optical element group is divided into the first blocks in the main direction and sub direction SD to constitute the first optical elements, the element has the deflection characteristics for making the incident light flux into the emission light flux deflected in the main direction, and the adjacent elements in the sub direction have the different deflection characteristics in the main direction. The second optical element group 63 is divided into the second blocks in the main direction to constitute the second optical elements. The plurality of first optical elements continuous to the main direction are grouped, and the emission light flux group in each group unit is deflected toward the second optical element opening as the deflection characteristics in the main direction of the first optical element. The optical axis of the second optical element is made to be eccentric in the sub direction SD approaching the optical axis of a transparent rod 51 with respect to the center position in the sub direction SD of the first optical element having the correspondence.SELECTED DRAWING: Figure 15
