PROBLEM TO BE SOLVED: To provide an incubator can prevent accidents to the incubator itself or other devices, a doctor, a nurse or others causing external force even if the external force is applied to a canopy of a newborn housing chamber.SOLUTION: An optical detector 38 in a control mechanism detects application of the external force to the canopy 26 of the newborn housing chamber, and a signal output section in the control mechanism outputs a signal that renders a driving mechanism for lowering and raising the canopy 26 non-operational when the application of the external force is detected. Accordingly, even if the external force is applied to the canopy 26 by bump, contact, putting some object or others, the driving mechanism does not continue or start to lower or raise the canopy 26 while the external force is applied to the canopy 26 because the driving mechanism is rendered non-operational.COPYRIGHT: (C)2010,JPO&INPIT【課題】新生児収容室の天蓋に外力が印加されても、保育器自体や外力の原因になった他の機器や医師及び看護士等に対する事故を未然に防止することができる、保育器を提供する。【解決手段】新生児収容室の天蓋26に対する外力の印加を制御機構の光検出器38が検知し、天蓋26を下降及び上昇させる駆動機構を非作動状態にする信号を制御機構の信号出力部が外力の印加の検知時に出力する。このため、天蓋26に衝突や接触や何らかの物体の載置等の外力の印加があっても、駆動機構が非作動状態にされるので、天蓋26に外力が印加されている状態で駆動機構が天蓋26の下降及び上昇をそのまま継続または開始することはない。【選択図】図1
