ABSTRACT:
A light shield for an x-ray film sheet cassette is provided with increased flexibility in its end portions to prevent bowing of the shield when it is subjected to abnormal forces in its center portion. This is accomplished by notching the front lip of the light shield in the end portions of the shield.
