Claims
- 1. A thermal printer for recording an image to thermosensitive recording material, comprising:a conveyor for conveying said recording material along a conveying path; a thermal head for thermally recording said image to said recording material being conveyed; a fixer lamp, having a long shape, for applying electromagnetic rays of a predetermined range of wavelength to said recording material being conveyed, for optically fixing said recording material; a driver circuit for driving said fixer lamp; and a printed circuit board on which said driver circuit is mounted, and to which said fixer lamp is secured.
- 2. A thermal printer as defined in claim 1, further comprising a pair of support plates, disposed on said printed circuit board erectly therefrom, for supporting said fixer lamp therebetween.
- 3. A thermal printer as defined in claim 1, wherein said recording material includes a support, and at least first, second and third thermosensitive coloring layers, overlaid on said support, for developing respective colors being different from one another, wherein said first coloring layer is disposed at a recording surface, said third coloring layer is disposed most deeply from said recording surface, and said first and second coloring layers have fixability to electromagnetic rays of respectively first and second ranges of wavelength;wherein said fixer lamp comprises: a first fixer lamp, disposed to extend crosswise to conveyance of said recording material, for emitting electromagnetic rays of said first range of wavelength; and a second fixer lamp, disposed near to said first fixer lamp to extend substantially in parallel therewith, for emitting electromagnetic rays of said second range of wavelength.
- 4. A thermal printer as defined in claim 3, wherein said printed circuit board and said fixer lamps have an equal length in a direction crosswise to conveyance of said recording material.
- 5. A thermal printer as defined in claim 4, further comprising two lateral plates, disposed substantially in parallel with each other, said fixer lamps being so extended that distal ends thereof are disposed beyond outer sides of said lateral plates, wherein said lateral plates exclude said distal ends from confrontation with said recording material, wherein said thermal head, a platen roller, and said conveyor are disposed between said lateral plates, and constitute a printing unit, said printing unit being secured to said printed circuit board.
- 6. A thermal printer as defined in claim 5, further comprising cutouts, respectively formed in said lateral plates, for receiving partial insertion of said fixer lamps.
- 7. A thermal printer as defined in claim 5, wherein each of said fixer lamps includes-one end bent in an L-shape substantially in parallel with conveyance of said recording material.
- 8. A thermal printer as defined in claim 5, wherein each of said fixer lamps includes two ends respectively bent in an L-shape substantially in parallel with conveyance of said recording material.
- 9. A thermal printer as defined in claim 5, wherein each of said fixer lamps has a U-shape including first and second portions, disposed substantially in parallel with each other, and so extended that said recording material is conveyed crosswise thereto.
