Abstract

A film holder is described for use in a dental X-ray film developing machine. The film holder has a stem portion, an engagement portion formed at one end of the stem portion and a film-mounting portion com-posed of two support portions formed at the other end of the stem portion and extending out in an opposing relationship from the stem portion. Plural film-mounting projections are provided at different levels in the direction of the thickness of the film holder in the proximity of each of free end portions and base portions of the respective support portions, whereby a film can be placed between the support portions while being held between the projections. Also described is a film mounting stage for mounting a film on the film holder. The stage has a wall for placing the film thereon and film pressers extending from individual peripheral edges of the wall in correspondence to the respective sides of the film, and defines a film-holder-receiving recess having substantially the same shape in plan as the film holder and a bottom wall lo-cated lower than the wall. The film holder and mount-ing stage permit easy mounting of the film on the holder.
