PROBLEM TO BE SOLVED: To provide an LED(light emitting diode) array head which can reduce the crosstalk of a luminous flux with a simple constitution. SOLUTION: To prevent lens slots from being blocked, a cylindrical light shielding member 3 is constituted by thin plates 31, 32 such as thin sheets or resin sheets. Since such thin plates 31, 32 has flexibility, if the member 3 that the size of a lens array in the longitudinal direction is slightly larger than the distance of the adjacent lens slots is formed, the dimensional difference is absorbed by slightly deflecting, and the plate 31 of the member 3 can be effectively engaged with the slot. |
