In FIG. 3, the difference from the above embodiment is that the temperature sensor 9 is attached via the temperature sensor spring 15, which is the use of the 0 spring 16, which allows the temperature sensor 9 to be placed in closer contact with the temperature sensor 9. If the mounting position is near the planar heaters 2a, 2b near the center of the heating chamber upper wall 6, the heating chamber upper wall 6 may curve toward the planar heaters 2a, 2b due to thermal expansion as heating progresses. The springs 15 can be kept in close contact with each other at all times, and the spring 15 absorbs unnecessary force in the event of shocks such as drops or vibrations.
This results in a highly reliable installation.
