PROBLEM TO BE SOLVED: To provide a heat treatment apparatus for improving treatment efficiency of material to be treated without requiring a large mounting space, for uniformly heating the material, and reducing generation of dust. SOLUTION: The heat treatment apparatus is provided with: a furnace body 2 with a gateway 15 that is opened in a crosswise direction; a drive device for turning a support member 4 around an axis in upper and lower directions so that a material 3 to be treated being supported by the support member 4 can be orbited around the axis in the upper and lower directions; and a heating device of the material 3 to be treated by circulation of hot air. The position of the support member 4 for the furnace body 2 is determined so that the material 3 to be treated can enter or exit from the furnace body 2 through the gateway 15 due to the orbiting. The material 3 to be treated can be supported or released by the support member 4 outside the furnace body 2. Shutoff members 61 are arranged between the support positions in a circumferential direction of the materials 3 by a support members 4, and are rotated together with the support member 4 so as to enter or exit from the furnace body 2 through the gateway 15 by the rotation. The shutoff member 61 can prevent flow of the hot air to the outside of the furnace body 2 when passing through the gateway 15. COPYRIGHT: (C)2005,JPO&NCIPI
