1. A radiography apparatus comprising:
a radiation generation device having a radiation source configured to generate radiation, a collimator configured to adjust an irradiation range of the radiation, and a first operating device configured to operate the collimator;
a radiography device that images a subject using the radiation;
a support that supports at least the radiation generation device in a case where the subject is imaged; and
a processor configured to function as:
an operation controller that invalidates an operation of the collimator using the first operating device in a case where the radiation generation device is present vertically downward relatively to the radiography device, and validates the operation of the collimator using the first operating device in a case where the radiation generation device is present vertically upward relatively to the radiography device.
