  • Patent number: 5235372
    Abstract: An automated dental x-ray system comprising a housing having a pair of reservoirs capable of storing relatively large quantities of developer and fixative agents therein. The developer and fixative reservoirs communicate via respective valves to a reaction chamber which includes one or more water fillers connected to an incoming water source. The reaction chamber includes a cover plate selectively movable between raised and lowered positions. A dryer cabinet is provided above the reaction chamber with an electric heat fan mounted thereto. Additionally, an x-ray cassette is provided which is mountable to the under surface of the cover plate and adapted to receive conventional x-ray film in the order and orientation of exposure. A large film rack for holding panographic and medical x-ray film during processing and a wall attachment to hold the large film rack and cassette while x-rays are being exposed is disclosed.
