Abstract
A size sensing X-ray cassette tray adapted for nesting within an X-ray table or a vertical holder, has a pair of longitudinally spaced opposed front and rear cassette engaging clamps linked together for movement in unison and slidably mounted upon the tray for centering and holding a cassette. A side sensing finger is slidably mounted upon the tray for movement at right angles to the clamp movements. A pair of right angularly related linear potentiometers are mounted upon the tray adjacent one of the clamps and finger, parallel to their direction of movements respectively. Wiper arms are connected to one clamp and finger have contacts slidably engageable with the respective potentiometer for establishing resistances in a circuit with the X-ray equipment proportional to the length and width of the cassette.
