Document Type and Number:
Japanese Patent JP7420043
Kind Code:
B2
Abstract:
A light receiver 212u provided on the upper side and a light receiver 212d provided on the lower side with respect to the optical axis of a light emitter 211 generate light reception signals corresponding to the light reception intensity of emitted light from the light emitter 211. A liquid level state determiner 30 determines a liquid level state on the basis of a signal level difference between the light reception signal generated by the light receiver 212u and the light reception signal generated by the light receiver 212d. It is not required to perform processing of captured image data, and even in a case where a liquid temperature is substantially equal to the outside air temperature, the state of a liquid level can be easily grasped.
