ABSTRACT:
There is provided an image exposure device in an image recording apparatus which has a simple and compact structure without requiring relatively high assembling accuracy. The light source portion 204 is formed with the plurality of LED chips 208 being arranged in groups. These LED chips 208 which emit light of colors of blue (B), green (G), and R (red) (when described below for each of the colors, the LED chip which emits light of blue is referred to as B-LED chip 208B, the LED chip which emits light of green is referred to as G-LED chip 208G, and the LED chip which emits light of red is referred to as R-LED chip 208R) are mounted onto a substrate 210 along the transverse direction of the photosensitive material 106 (i.e., the main scanning direction) in accordance with the same arrangement rule. Namely, the totaled six rows of LED chips 208 are arranged in a zigzag manner in the plan view of the substrate 210.
