Abstract:
In order to adjust a level of a detection signal output from an optical sensor in accordance with a state of a target object in a liquid ejecting apparatus, the optical sensor includes a light emitting element operable to irradiate the detected object and a light receiving element operable to detect a light amount which varies in accordance with the state of the target object. The detection signal is output from the optical sensor, based on the detected light amount. Luminance of the light emitting element is adjusted based on the detection signal, so that the level of the detection signal falls within a prescribed range.
