Claims

[Scope of Claim for Utility Model Registration] (1) In a holding mechanism that stably attaches a film cassette used for medical X-ray photography to a film cassette holding means from the side, the film is held in the correct orientation. The cassette is constructed so that the projected side surface shape in the insertion direction is asymmetrical and asymmetrical, and the film cassette holding means can be inserted through the projected side surface shape of the film cassette, and the asymmetrical portion of the projected side surface shape A film cassette holding mechanism for a medical X-ray apparatus, characterized in that the film cassette holding mechanism for a medical X-ray apparatus is configured to have an insertion space having a side surface shape projected in the insertion direction and having a restriction portion that follows the contour of the film cassette. (2) Claims for registration of a utility model in which the film cassette has a recess or a protrusion that removably engages with the elastic engaging body of the holding means, which is positioned at a predetermined position in the insertion direction with respect to the holding means. The holding mechanism according to item 1.
