Colorimetric device and printing apparatus

A colorimetric device comprising:

• a colorimetric unit that measures a color of a subject positioned at a predetermined colorimetric position;
• a conveyance unit that conveys a predetermined sheet to the colorimetric position;
• a backing member that is pressed by the predetermined sheet conveyed to the colorimetric position by the conveyance unit in a perpendicular direction relative to a surface of the predetermined sheet, and is disposed behind the predetermined sheet at the colorimetric position when viewed from the colorimetric unit;
• a supporter that supports the backing member in a manner that the backing member can move in the perpendicular direction;
• and
• a holder that holds the color tile member disposed on the backing member in a state that the amount of movement of the backing member in the perpendicular direction by a color tile member being thicker than the predetermined sheet and disposed on the backing member is larger than the amount of movement of the backing member in the perpendicular direction by the predetermined sheet.
