<P>PROBLEM TO BE SOLVED: To suppress noise light generated at a bottom surface of a prism or a cavity, and to more accurately detect a residual state of a liquid. <P>SOLUTION: A liquid consumption apparatus includes a detection portion in which a light emitting portion and a light receiving portion are arranged, a liquid container that houses a liquid and in which a prism is disposed, a carriage with respect to which the liquid container is detachable, and in which an opening is provided in a position that opposes the prism, and a light shielding portion disposed in the opening in the carriage. When a driving portion moves the carriage in a direction in which the light emitting portion and the light receiving portion are arranged, noise light produced by the prism bottom surface or cavity is suppressed, as a result of the light shielding portion blocking part of irradiated light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
