Abstract
In a carriage of a liquid drop discharging device, an encoder sensor is arranged to read slits on a linear scale at a slit reading position. The carriage includes a stain detection part that detects a stain on the linear scale based on position information output from the encoder sensor. An encoder sensor moving part moves the encoder sensor from the slit reading position in a width direction of the linear scale. An encoder sensor movement control part controls movement of the encoder sensor from the slit read position by the encoder sensor moving part based on stain information output from the stain detection part.
