Abstract
A dental X-ray film developing machine is described. The machine has a cylindrical housing, a motor fixed on the housing, an arm for being driven by the motor, and a film holder for being brought into detachable engagement with the arm whereby development processing of a film mounted on the film holder is conducted while the film holder makes a full turn within the housing. Plural tanks, including a tank containing a developer and another tank containing a final processing solution such as water, are removably arranged along a peripheral wall of the housing. A film-holder-inserting portion is located before the developer-containing tank relative to the turning direction of the arm so that the film holder with the film mounted thereon can be positioned at a point where the film holder can be brought into engagement with the arm which is being driven. A device for detaching the film holder from the arm is provided after the final-processing-solution-containing tank relative to the turning direction of the arm.
