X-ray apparatus with improved film cassette clamping and size sensing means

摘要: A pair of clamps interconnected by a pulley and cable system including substantially inextensible cables clamp opposite side regions an X-ray film cassette. locking mechanism serves to prevent retractive movement the urge them firmly into engagement with cassette hold it in alignment beam axis. The have spaced parallel reaches defining unobstructed central region therebetween for phototiming control exposure. One interconnecting is reeved around connected electrical signal means providing representative size being clamped.
