Abstract
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 having a cavity is disposed, a carriage with respect to which the liquid container is attachable and 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 portion is suppressed, as a result of the light shielding portion blocking part of irradiated light.
