    摘要: Disclosed is a liquid detection device wherein a condition in which there is no liquid remaining in either a storage member or a tank and a condition in which there is liquid remaining in at least either the storage member or the tank are easily discriminated using a single mechanism. When there is oil (liquid) remaining in at least either the oil tank or the impregnated member (storage member), light emitted from a light emitting part is passed into the oil through a prism face located partway along the light path, and does not reach a light receiving part. On the other hand, when there is no oil remaining in either the oil tank or the impregnated member, the emitted light reaches the light receiving part. When the oil tank itself is not mounted, the light emitted from the light emitting part also reaches the light receiving part. When the light emitted from the light emitting part is not detected by the light receiving part, a controller determines that there is oil.
