Fixing device

Abstract

Abstract PURPOSE:To raise thermal efficiency by setting small a gap between a heat source and recording paper, by providing a shutter part flush with a paper guide part and integrally. CONSTITUTION:A fixing device 1 is provided with a heat source 3 such as an infrared lamp, etc., at a prescribed interval on the upper part of a carrying path 2 for carrying a recording paper P, a shutter member 4 on which a paper guide part 4a and a shutter part 4b have been provided integrally is provided so as to be movable between this heat source 3 and the carrying path 2, and at an abnormal time, the shutter part 4b is interposed between the carrying path 2 and the heat source 3, and at a normal time, the paper guide part 4a is interposed. As for a shutter part 15, a heat resisting material such as stainless steel, an aluminum alloy, etc., is formed in a shape of a plate, and also as for a paper guide part 16, plural pieces of bar bodies 16a consisting of a heat resisting material which is excellent in formability and workability, such as metallic ceramics, etc., are embedded and screwed into one side edge of the shutter part 15, and fixed as one body by using a suitable method of press fitting, spot welding, etc.
