Infrared heating device

Abstract

Infrared heating apparatus irradiates a member to be heated with infrared rays from infrared source to heat the member, and sets heated region of the member to be heated with use of shielding member that restricts transmission of infrared rays. The infrared heating apparatus includes: a pair of holding members each having a plate shape that allow the infrared rays to be transmitted therethrough being disposed to intersect with an irradiation direction of the infrared rays between the infrared source and the member to be heated, and the shielding member being interposed and held between the holding members, and being a metal sheet, metal foil or a metal film, which has a prescribed shape that restricts transmission of the infrared rays, and the holding members being placed on each other to be in close contact with each other while the shielding member is interposed between the holding members.

1 . An infrared heating apparatus that irradiates a member to be heated with infrared rays from an infrared source to heat the member to be heated, and sets a heated region of the member to be heated with use of a shielding member that restricts transmission of the infrared rays, the infrared heating apparatus comprising:
 a pair of holding members each having a plate shape that allow the infrared rays to be transmitted therethrough being disposed in such a posture as to intersect with an irradiation direction of the infrared rays between the infrared source and the member to be heated, and the shielding member being interposed and held between the pair of the holding members, and the being a metal sheet, metal foil or a metal film, which has a prescribed shape that restricts transmission of the infrared rays, and the pair of the holding members being placed on each other so as to be in close contact with each other while the shielding member is interposed between the pair of the holding members.   
     
     
         2 . The infrared heating apparatus according to  claim 1 , wherein
 the pair of the holding members are heat-resistant glass plates.   
     
     
         3 . The infrared heating apparatus according to  claim 2 , wherein the shielding member is the metal film that is vapor-deposited on a surface on the member to be heated side of the heat-resistant glass plate of a pair of the heat-resistant glass plates located on the side opposite from the member to be heated.
