Description

Technical Field

[0001] The utility model relates to the technical field of film reproducing apparatuses, in particular to a film digital reproducing apparatus. Background Art

[0002] Reshooting refers to the film digitization solution that uses a digital camera with a macro lens to shoot negatives. Compared with electronic separation and scanning, it is more suitable for non-commercial digital film users who have high demands for image quality and have certain post-production capabilities and color theory foundation. As one of the classic photography methods, film still has a strong charm. Although digital technology is constantly improving, film has not withdrawn from the stage of history, and reshooting has become the most convenient way to digitize film.

[0003] In the process of copying film, the stage of the copying instrument is relatively empty. Generally, the film is directly aligned with the light source placed on the stage, and then photographed by a digital camera suspended above. The film itself is stored curled, so there will be a certain curvature or unevenness when it is flattened, which causes the copied image to be curled, affecting the picture quality. In addition, in order to improve the uniformity of light, the volume of the light source is generally larger. When the digital camera is focusing, there are more light sources at the bottom that exceed the coverage range of the film, which will affect the ambient light of the film, and thus affect the layering of the picture after copying.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The film digital copying instrument comprises: a base 1, a copying frame 2 is installed on the base 1, a camera 3 is arranged on the copying frame 2, a copying platform body 4 is arranged on the surface of the base 1 directly below the camera 3, and a switch 8 is connected to the end of the copying platform body 4 through a wire, and the switch 8 supplies power to the copying platform body 4 through the wire;

[0027] Both ends of the copy table body 4 are provided with lens guide rails 5, and films 7 are shuttled inside the two lens guide rails 5. The film 7 passes through the top of the copy table body 4 and is pressed on the copy table body 4 by the film pressing plate 6 adsorbed thereon;

[0028] A window groove 9 is opened inside the copying platform body 4, and an LED light source 10 is embedded in the bottom of the inner wall of the window groove 9. Anti-Newton ring glass 16 is pasted on the copying platform body 4, and the position of the anti-Newton ring glass 16 corresponds to the position of the LED light source 10. Electromagnets 11 are embedded in the surface of the copying platform body 4 on both sides of the anti-Newton ring glass 16, and the electromagnets 11 are electrically connected to the switch 8.

[0029] Among them, the two ends of the copying platform body 4 are sunken to form a stepped card slot 13 on its surface, and the inner wall of the card slot 13 is integrally provided with a card cap 14, and the lens guide rail 5 is engaged in the card slot 13. The card slot 13 is used to limit the lens guide rail 5 at the two ends of the copying platform body 4, thereby improving the stability of the film 7 located on the copying platform body 4, so that the film 7 between the two lens guide rails 5 will not shake, thereby ensuring the clarity of the copy.

[0030] Among them, a sunken groove 15 is provided on the surface of the copying table body 4, and an anti-Newton ring glass 16 is pasted inside the sunken groove 15, and a narrow gap for the film 7 to pass through is formed between the surface of the anti-Newton ring glass 16 and the adsorbed pressing plate 6. By providing the sunken groove 15, sufficient space is reserved for the pasting of the anti-Newton ring glass 16, so that the copied film 7 will not be affected by the reflected light, thereby improving the quality of the copied picture.

[0031] Among them, the lens guide rail 5 includes a holder 51, on which a rail cover 52 is integrally formed, and a rail groove 53 for the film 7 to pass through is formed between the rail cover 52 and the holder 51, and slide grooves 54 are provided on both sides of the inner wall of the rail groove 53, and the inner wall of the slide groove 54 is slidably connected with the side edge of the film 7. The side edge of the film 7 is contacted with the inside of the lens guide rail 5 through the opened slide groove 54, so that the middle part of the film 7 passing through the lens guide rail 5 is suspended in the air, thereby avoiding scratches on the film 7 when it shuttles.

[0032] Among them, the inner edge of the end of the track groove 53 of the lens guide rail 5 away from the copy table body 4 is recessed to form a bevel, and the track cover 52 of the lens guide rail 5 close to the copy table body 4 is extended and buckled on the pressing plate 6. The bevel formed by the recessed groove on the lens guide rail 5 is used to guide the film 7 to be inserted therein, so that the inserted film 7 is directly introduced to the extent of contact with the slide groove 54 without slowly searching. In addition, when the film 7 shuttles, the film 7 to be entered into the lens guide rail 5 is guided to avoid the situation where the edges and corners contact the film 7.

[0033] Among them, the pressing plate 6 includes a cover plate 61, which is made of a magnetic element metal material as a whole. A copy window 62 is opened on the surface of the cover plate 61, and the width of the inner wall of the copy window 62 corresponds to the width of the film 7. By forming a copy window 62 corresponding to the width of the film 7 on the pressing plate 6, the part of the LED light source 10 that exceeds the film 7 is completely covered by the pressing plate 6, and only the light source that passes through the film 7 can be released from the copy window 62, thereby isolating the ambient light generated by the LED light source 10, thereby improving the layering of the picture after copying.

[0034] Among them, the surfaces of the cover plate 61 near the four corners are all provided with positioning holes 63, and the inner walls of the positioning holes 63 are plugged with positioning anchor blocks 12, and the positioning anchor blocks 12 are embedded in the main body 4 of the copying table. When the pressing plate 6 is adsorbed by the main body 4 of the copying table, the positioning anchor blocks 12 are inserted into the positioning holes 63 to achieve the effect of automatically calibrating the adsorption position of the pressing plate 6, without the need to slowly debug and calibrate the copying.

[0035] Working principle: when performing the copying work, first let the film 7 pass through the lens guide 5 to limit the copying section on the copying table body 4, then cover the pressure plate 6 on the copying table body 4, and then let the developing section reach the anti-Newton ring glass 16. After adjustment, turn on the switch 8, so that the pressure plate 6 is adsorbed and pressed on the copying table body 4 by the electromagnet 11, completing the film pressing work, and then use the control of the light intensity of the LED light source 10 to cooperate with the camera 3 to perform the copying work.
