Abstract:
A heat sensitive type printer comprising:a paper transporting device for transporting a heat sensitive recording paper along a paper transport path, said heat sensitive recording paper having at least a coloring layer; at least a thermal head having a heating element array extending in a transverse direction to the paper transport path, said thermal head heating said heat sensitive recording paper through said heating element array as said heat sensitive recording paper is transported along the paper transport path, to record an image line by line on said coloring layer; at least a surface luminous device having a plane light emission surface that faces the paper transport path, for radiating electromagnetic rays toward said heat sensitive recording paper, to fix said coloring layer after having said image recorded thereon; and at least a cooling device for cooling said thermal head and said surface luminous device, said cooling device comprising a cooling air generating device that sends air toward said thermal head and said surface luminous device, and an air guide that guides the cooling air to flow along said light emission surface of said surface luminous device in a lengthwise direction of said paper transport path.
