发明名称 LIGHTPROOFED DENTAL RADIOGRAPHIC FILM DEVELOPER
摘要 A small X-ray film developer has a lightproof housing having a door through which a plurality of exposed films in their lightproof wrappers may be introduced by sliding the wrapper flaps over the thin edge of a plate adapted to slide toward and away from an identification card holder which is adapted to be rotated and to be raised and lowered. After the card and films have been introduced the door is closed and a rod under the flaps is rotated about 135 DEG around the plate to open the wrapper flaps exposing a small portion of each film so that each may be contacted by gummy portions on the card when it is turned. The plate is then slid away from the card thus withdrawing the films and the card is turned and lowered dipping the films into a developing tank. Valves controlling sources of developer, fixer and water are then operated to supply the tank successively therewith. The card is then raised and a fan is turned on to dry the developed films. The door is then opened and the card with attached developed films is removed. A film cover with appropriate windows for the films is then attached to the card leaving its identifying inscriptions and the films readable.
