Automatic filmer capable of centering the cassette with respect to an x-ray window and measuring the width and length thereof. Oppositely disposed channels are used to center the cassette about a first center line and measure the width thereof. A gripper assembly is used to draw the cassette into the housing and determine the length of the cassette. A carriage assembly moves the cassette within the housing so as to expose the cassette to x-rays within the x-ray window.
