<p>PURPOSE: To reduce space for arranging a plurality of collimator change carriages by providing a recess capable of housing the carriage base of a separate adjacent carriage. CONSTITUTION: A carriage base 17 is provided with a recess capable of housing the carriage base 17 of a separate adjacent collimator change carriage. In other words, branch type members 17b and 17c are formed to be extended forward from a branch type member 17a, and fitted with casters 18. Also, branch type members 17d and 17e are formed to be extended backward from the member 17a, and fitted with casters 18. In this case, the distance of the members 17d and 17e from the pillars 16 thereof are set to be longer than the distance of the members 17b and 17c from the pillars 16 thereof. According to this construction, when collimator change carriages of the same type are arranged in such a state as adjacent to each other between the members 17d and 17e, the members 17b and 17c of the adjacent carriage can be housed. As a result, the adjacent carriages can be positioned closer to each other.</p> |
