Abstract

Abstract Translated from Japanese (57)【要約】 【課題】加熱ローラの加熱源として少なくとも加熱ロー ラ外部から加熱する外部加熱手段を備えた加熱装置にお いて、加熱ローラの異常昇温を早期に検知することで安 全性を確保することを課題とする。 【解決手段】本発明では、加熱源により加熱される加熱 ローラ1と、該加熱源として少なくとも加熱ローラ外部 から加熱する外部加熱手段3と、該外部加熱手段への電 力供給を遮断する安全対策用温度検知部材S2を備えた 加熱装置において、前記外部加熱手段3が加熱ローラ1 を加熱する加熱領域H上に、前記安全対策用温度検知部 材S2を配置する構成とする。これにより、加熱装置の 異常昇温を安全対策用温度検知部材S2で早期に検知す ることができ、安全性を確保することができる。 (57) [Summary] In a heating device provided with at least an external heating means for heating from outside the heating roller as a heating source of the heating roller, safety is secured by detecting an abnormal temperature rise of the heating roller at an early stage. That is the task. According to the present invention, a heating roller 1 heated by a heating source, an external heating means 3 for heating at least from the outside of the heating roller as the heating source, and a safety measure for shutting off power supply to the external heating means are provided. In a heating device provided with a temperature detecting member S2, the external heating means 3 is a heating roller 1 The temperature detecting member S2 for safety measures is arranged on the heating area H for heating. Thereby, the abnormal temperature rise of the heating device can be detected at an early stage by the safety measure temperature detection member S2, and safety can be ensured.
