1. A mammography apparatus comprising:
an arm that accommodates a radiation source emitting radiation toward a breast and is supported by a stand;
a first cooling fan that is disposed on a stand side with respect to the radiation source in the arm, sucks air from an outside of the arm, and discharges air that has cooled the radiation source from a first exhaust port provided on the stand side with respect to the radiation source;
a projector that is disposed in the arm and projects information;
a second cooling fan that is disposed between the projector and the first exhaust port in the arm, sucks a part of air directed from the first cooling fan to the first exhaust port, blows the sucked air toward the projector to cool the projector, and has a flow rate smaller than that of the first cooling fan; and
a second exhaust port that is provided separately from the first exhaust port and through which air that has cooled the projector is discharged.
