An incubator according to the present invention will be able to 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 chamber. An optical detector in a control mechanism detects application of external force to the canopy of the newborn chamber, and a signal output section in the control mechanism outputs a signal that renders a driving mechanism for lowering and raising the canopy non-operational when the application of external force is detected. Accordingly, even if external force is applied to the canopy by bump, contact, putting some object or others, the driving mechanism will not continue or start to lower or raise the canopy while the external force is applied to the canopy because the driving mechanism will be rendered non-operational.
