PURPOSE:To prevent the occurrence of unevenness in heating, by constituting a rotary disc such that the disc turns through a transmission shaft of motor even at a heating time. CONSTITUTION:A device is provided with a rotary disc 9 consisting of a projection 10 at a center part, a slope surface 11 extending upward from the lower end of the projection 10, and a support part 14 for a rotary tray 5. An engaging support part 16 engaging a transmission shaft 4 of a motor 2 is mounted to the under-surface of the projection 10, while an opening 12 having a rise curve part 13 of which the periphery is bent downward, is formed in the slope surface 11. The rotary disc 9 is constituted such that it turns by means of a transmission shaft 4 of a motor 2 even at a heating time of a heater 7. This constitution causes a radiating heat to be agitated by the raised part 13 when the rotary disc 9 turns, an this enable to perform a uniform heating and permits the prevention of the occurrence of unevenness is heating. |
