【０００３】
【発明が解決しようとする課題】
しかしながら、上記のような従来の構成では、例えば、加熱制御手段としてモータを用いた場合に駆動電圧として駆動開始直後に必要な電圧は駆動途中に必要な電圧より高い電圧であり、駆動開始から終了まで一定の電圧のため、駆動途中には必要のない電力を消費してしまい、電池を電源としたときは、電池寿命を短くするという課題を有していた。
【０００４】
また、電池を電源として駆動する場合、電圧の高いときと低いときでは加熱制御手段の駆動速度に差がでるという課題や、電池の内部抵抗が増加してくると加熱制御手段駆動直後に電圧降下を起こし、制御手段であるマイクロコンピュータのリセット電圧以下になり、マイクロコンピュータがリセットするという課題を有していた。
【０００５】
【課題を解決するための手段】

【０００６】
また本発明によれば加熱制御手段の駆動前に負荷抵抗を駆動させ電圧を測定し、その電圧に応じて加熱制御手段の駆動速度を一定に保つように駆動信号決定する構成としたものである。上記発明によれば加熱制御手段の駆動時の駆動速度を一定に保つことができる。
【０００７】
また本発明によれば加熱制御手段の駆動前に負荷抵抗を駆動させ電圧を測定し、その電圧が所定値以下の場合には加熱制御手段の駆動信号を出力しない構成としたものである。上記発明によれば電池電圧の内部抵抗増加時に加熱制御手段を駆動した際の電圧降下による制御手段のリセットを防ぐことができる。
