1. A colorimetric apparatus comprising:
an apparatus body;
an opening forming member in which an opening through which light received from an object under measurement is taken into an interior of the apparatus body is formed, the opening forming member being disposed at a bottom of the apparatus body;
an incident light processor that processes light incident through the opening; and
a shutter configured to shift between a closed position, at which the shutter covers the opening, and an open position, at which the shutter opens the opening, colorimetry being performed with the shutter at the open position, wherein
the apparatus body has
a shifting member that is shaped along an inner surface of the apparatus body so as to enclose the opening forming member, wherein the shifting member is configured to shift between a projection position, at which the shifting member projects the most in a first direction in which the shifting member projects from the bottom, and a retraction position, at which the shifting member retracts the most in a second direction opposite to the first direction,
a first spring that presses the shifting member in the first direction, and
an operation conversion unit that has a second guide groove formed in the shifting member, wherein the operation conversion unit converts a shift operation of the shifting member with respect to the apparatus body to a shift operation of the shutter,
in a state in which the shifting member is at the projection position, the shutter is at the closed position, and
when the shifting member shifts from the projection position to the retraction position, the shutter is shifted from the closed position to the open position by the operation conversion unit.
