A movable pressing and light-shielding mechanism for digital stereo image printing comprises a base (1), portal frames (2), a photosensitive platform (3) and exposure system equipment (4). The base (1) is provided with a recess inside which the photosensitive platform (3) is disposed. There are two portal frames (2) provided in parallel. The two portal frames (2) are fixed on the base (1), and a sliding rail (22) is arranged between said two frames. A screw rod is arranged in the sliding rail (22). One end of the screw rod is connected with a motor (12). The motor (12) is connected with the exposure system equipment (4). The top surface of the exposure system equipment (4) is connected with the screw rod. A laser scan line opening is arranged on the bottom surface of the exposure system equipment (4). An optical-grating pressing mechanism (31) and an optical-grating pressing plate are provided on the photosensitive platform (3). The exposure system equipment (4) is operated synchronously with the optical-grating pressing mechanism (31) and the optical-grating pressing plate, and the stereo printing is completed by moving the photosensitive platform (3). The mechanism has the advantage of a sound structure, stable performance, and colorful stereoscopic image printing. |
