摘要:
A clamping arrangement (300) essentially comprising two lever arms (301,302) driven at one end by a solenoid (307) and having a resilient clamp pad mounted on a flexure member at the other end thereof. The clamp pad (314) is made of a resilient material such as, for example, urethane and has four non-parallel side walls defining an upper face which is complementary to the radial face (102) of the scanning apparatus gate. The sloping side walls of the clamp pad act as a light baffle to prevent reflected light from entering the imaging lens, and the pad is gimballed so that any variations between the upper surface of the clamp pad and the radial surface of the gate will be eliminated attain as perfect a match therebetween as is possible. In another embodiment of the clamping arrangement, a single arm (330) can be utilized in place of the dual arm arrangement described above. The single arm has a Y-shape in which the clamp pad (314) is supported on the branched end of the arm and the solenoid drives the single member. An additional clamp pad (320) can be provided for clamping laminated paper attached to the film for a reprocessing order after the film itself has been clamped by the first-mentioned clamp pad against the gate in the area of the aperture. This additional clamp (320) allows the scanning apparatus to run reorders with laminates, including the Kodak laminate system as well as of the "URS" system which is also well known in the photographic film lab industry. The additional clamp is arranged such that there is no relative motion between the film and the paper so as to avoid any mismatch between the tension in the film and the tension in the paper. If there is some difference between the two tensions, the additional clamp avoids the film being ripped off the paper.
