Abstract

PURPOSE: To obviate the unnecessary non-uniform distribution of the heating temperature, eliminate the influence due to the thermal convection, and make it possible to carry out a uniform and stable heat treatment by providing a reflecting member of radiation heat with a piercing hole which communicates with outside the device.
CONSTITUTION: Part of radiaing ray radiated from radiating beam source 2 directly radiates the heat sensitive member transported by direct guide 6 and feed roller 7, and part of the radiating ray is reflected and condensed by reflecting shade 1 in order to contribute to heating. This radiating ray heats also the air between the reflecting shade 1 and the heat sensitive member to produce the thermal convection. Hole 4 through which this heat convection is sent out of the device is pierced on the reflecting shade, and the size of the hole 4 is in the range of the reflecting efficiency which is not extremely reduced, and the most effective size is an oblong one whose width is a little longer than the diameter of the source 2. Hence the radiating heater device in which the influence due to the heat convection can be removed and the uniform and stable heat treatment can be done can be obtained.
