| Zusammenfassung: | To improve the uniform heating property.SOLUTION: A heating apparatus comprises a heating plate, a plurality of heaters, and a pair of rod-like members. The heating plate includes a heating surface and a plurality of concave parts positioned at a back surface opposite to the heating surface. The plurality of heaters are arranged at the plurality of concave parts, respectively. The pair of rod-like members hold a heater group arranged in a long direction of the rod-like member. The heater includes a heater main body and a cover member surrounding an outer peripheral surface of the heater main body. The pair of rod-like members face each other across the cover member of the heater included in the arranged heater group.SELECTED DRAWING: Figure 8
【課題】均熱性の向上を図ること。【解決手段】加熱装置は、加熱プレートと、複数のヒータと、一対の棒状部材とを備える。加熱プレートは、加熱面と、加熱面とは反対の裏面に位置する複数の凹部とを有する。複数のヒータは、複数の凹部にそれぞれに位置している。一対の棒状部材は、複数のヒータのうち、棒状部材の長手方向に配列されたヒータ群を保持する。ヒータは、ヒータ本体と、ヒータ本体の外周面を囲むカバー部材とを有する。一対の棒状部材は、配列されたヒータ群が有するヒータのカバー部材を挟んで向かい合う。【選択図】図８ |
