Abstract
Abstract An image recorder which requires a smaller amount of space for installation and which employs a simplified structure and eliminates moving parts in an image recording section. A recording head is provided having three linear arrays of light-emitting elements, such as light-emitting diodes, emitting light in the three primary colors RGB and arranged in a direction perpendicular to a direction in which a color photosensitive material is conveyed. The light-emitting elements of each array may be mounted on a respective flat plate base along side edge faces thereof. The side edge faces of the various bases are arranged opposite to one another.
