Abstract:
A light emitting substrate has a plurality of first light emitting portions arranged in a main scanning direction and a second light emitting portion disposed in a direction intersecting the main scanning direction with respect to the array of the plurality of first light emitting portions. A lens array has a plurality of first lenses, each of which is disposed to face each of the plurality of first light emitting portions, and a second lens for the second light emitting portion. A direction of the emitted light from the second light emitting portion has a slope with respect to a straight line which extends perpendicularly from a light emitting face of the corresponding second light emitting portion.
