Abstract: A printer includes a spectroscope and a carriage moving unit. The spectroscope includes a wavelength-selective interference filter on which light from a measurement target is incident, and the carriage moving unit moves the spectroscope in an X direction with respect to the measurement target. If the measurement target is a color patch, the spectroscope performs spectrometry by changing a wavelength of light passing through the wavelength-selective interference filter in a first period during which the spectroscope is moved in the X direction, and passes light of an initial wavelength through the wavelength-selective interference filter at a start of measurement and at an end of measurement in the first period. A first output value that is a measured value from the spectrometry at the start of measurement is compared with a second output value that is a measured value from the spectrometry at the end of measurement.
