Abstract
A heating apparatus which forms an image by heating a sheet-form material carrying image data. The heating apparatus comprises a heater, which is disposed at an axial center portion of the sheet-form material, for directly heating the sheet-form material to a temperature suitable for heat developing processing, and rings or a cylinder for rotating and allowing the sheet-form material to be exposed to the heater. The sheet-form material can be rotated on either an inner or outer surface of the rings or an inner surface of the cylinder. In addition, a plurality of rings can be used which correspond to differing widths of sheet-form material.
Claims27
A heating apparatus which forms an image by heating a sheet-form material, the sheet-form material carrying image data thereon, said heating apparatus comprising:
- a heater, disposed at an axial center portion of the sheet-form material, for directly heating the sheet-form material to a temperature at which heat developing processing occurs;
- and
- a plurality of winding rings disposed at positions corresponding to both transverse direction ends of the sheet-form material, the winding rings contacting the sheet-form material such that the sheet-form material is wound around along the winding rings, thereby curving the sheet-form material in a circular arc shape in a state in which an entire inner circumferential surface of the sheet-form material, in which the image data is carried thereon, is directly exposed to the heater.
A heating apparatus which forms an image by heating a sheet-form material, the sheet-form material carrying image data thereon, said heating apparatus comprising:
- a heater, disposed at an axial center portion of the sheet-form material, for directly heating the sheet-form material to a temperature at which heat developing processing occurs;
- and
- a cylindrical member, contacting the sheet-form material such that the sheet-form material is curved along an inner circumferential surface of said cylindrical member, thereby curving the sheet-form material in a circular arc shape in a state in which an entire inner circumferential surface of the sheet-form material, in which the image data is carried thereon, is directly exposed to the heater.
A heating apparatus which forms an image by heating a sheet-form material, the sheet-form material carrying image data thereon, said heating apparatus comprising:
- a heater, disposed at an axial center portion of the sheet-form material, for directly heating the sheet-form material to a temperature at which heat developing processing occurs;
- and
- a plurality of winding rings, wherein at least one of said winding rings is positioned at a first transverse direction end of the sheet-form material, and wherein each remaining winding ring of said winding rings is movable to be positioned to correspond to a predetermined spaced widths according to predetermined width dimensions of a plurality of sheet-form material, wherein the winding rings contact the sheet-form material, thereby curving the sheet-form material in a circular arc shape in a state in which image data carried thereon is exposed to the heater.
