FLOW CAMERA FOR LARGE DOCUMENT REPRODUCTIONS HAVING LENS ADJUSTMENT AND DOCUMENT FEED CONTROL MECHANISM
摘要
A flow camera apparatus (10) operable for photographing large original documents in continuous, moving fashion includes a camera (74) located within the housing (12). An aperture adjustment mechanism (86) allows adjustment of the camera aperture from the outside of the housing (12) without opening the housing (12). The iris adjustment mechanism also allows the aperture to be changed during photographing of a document. The apparatus includes lamps (214, 216 and 218) for illuminating the document during photographing and a "T" mask assembly (22) provided with baffles (204 and 208) for allowing only light reflected from the document to enter the image path (88) to the camera (74). The apparatus (10) also includes precisely balanced detectors (126) for detecting entry of a document into the apparatus (10).
