A film changing apparatus automatically replaces an exposed X-ray film accommodated in a cassette with a new or unexposed X-ray film. Unloading and loading of a film is effected in the vertical direction. Thus, the apparatus saves space in the horizontal direction. Furthermore, unloading of a film from the cassette is effected by gravity, thereby simplifying the structure of the mechanism for changing films, and thus allowing the size of the apparatus to be reduced as a whole.

A cooling device includes a heat dissipating unit that is in contact with an object to be cooled and dissipates heat, and an air blowing unit that takes therein air and blows the air to the heat dissipating unit. The heat dissipating unit includes a first stage portion and a second stage portion that have a difference in level therebetween. The air blowing unit includes a first inlet port that takes therein air from outside, and an outlet port that exhausts the taken-in air. The first inlet port faces the first stage portion, and the outlet port faces the second stage portion.
