Holder for positive and negative film

technical field

The invention provides a clamping device, especially a clamping device capable of placing a positive film and a negative film.

Background technique

With the vigorous development of digital technology, the storage of image data has gradually evolved into a digital format storage method. For example, traditional image media, such as planar photos, slides, film negatives, etc., can store the image data of planar photos, slides, and film negatives in digital form through scanning by an image processing device, and become available in Data in digitized format modified by actual operation on a computer. In addition, when scanning transparent documents, such as transparencies, slides, negatives, etc., a transmissive scanner in the optical image processing device can be used to assist the image processing device in scanning. Transmissive image processing refers to projecting a light through the transparent document to be scanned, so that the image on the transparent document can be converted into electronic data in digital form by the image processing device.

In the prior art, when the image processing device scans a transparent document, it needs to use a film fixing clip to fix the position of the positive film (positive) or negative film (negative). There are two ways to scan transparent documents: one is to place the film holder on the light-transmitting platform of the image processing device to fix the position, and the other is to assemble the film holder on the backlight plate of the image processing device.

The commonly used film holders have different designs according to different transparent files. Please refer to FIG. 1 , which is a schematic diagram of a negative film holder 100 in the prior art. The film holder 100 has a holder base 110 and a clamp cover 120. The holder base 110 has a negative guide groove 112 for carrying a long negative film. After the negative film is placed on the holder 110 , the negative film is fixed by pressing the cover 120 . Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a negative film holder 200 in the prior art. The negative film holder 200 has a carrying seat 210, and there are a plurality of positive film guide grooves 212 on the carrying seat 210, so the carrying seat 210 can place multiple positive films at the same time. After the positive film is placed on the carrier 210, the negative film holder 200 can be placed on the light-transmitting platform of the image processing device or assembled on the backlight plate of the image processing device for scanning.

Next, please refer to FIG. 3 . FIG. 3 is a schematic diagram of a negative film holder 300 for placing positive and negative films in the prior art. The negative film holder 300 combines the functions of the negative film holder 100 shown in FIG. 1 and the negative film holder 200 shown in FIG. 2 , and the structure of the negative film holder 300 is divided into two parts. The other part is the same as the negative film holder 200 and can be used to fix the positive film; this is because the shape and size of the positive and negative films are different, so the positions for placing the positive film and the negative film are still designed separately. The structure of the film holder 300 is the same as that of the film holders 100 and 200 , so it will not be described again.

Because the shape and size of the positive film and the negative film are different, the negative film holders for fixing the positive film and the negative film are designed separately in the prior art. When a negative film is to be scanned, the negative film holder 100 must be used; when a positive film is to be scanned, the negative film holder 200 of the positive film must be used. In this way, the hardware cost is increased, and the complexity of storing various auxiliary scanning components is increased. Even if the manufacturer provides the film holder 300 to the user, the cost is almost the same as that of providing two film holders 100 and 200 , and the user may still lose the film holder 300 .

In addition, some manufacturers combine the negative film holder on the backlight board of the image processing device, but they are still limited by the different shapes and sizes of the positive and negative films, so the negative film holder combined on the backlight board of the image processing device is still a negative film There are two kinds of folders 100 and 200. In use, the desired film folder should still be selected according to the scanned transparent document.

No matter how the transparent document is scanned, differently designed negative holders 100 , 200 or 300 are still used in the prior art, which is expensive and inconvenient for users to use and store. Therefore, there is a need for a design of a film holder that can reduce costs and is convenient to use.

Please refer to FIG. 4 . FIG. 4 is a schematic diagram of a clamping device 600 capable of placing positive and negative films according to the present invention. The clamping device 600 includes a clamping seat 610 and a clamping cover 620 , and the clamping cover 620 is buckled on the clamping seat 610 in a manner that can rotate relative to the clamping seat 610 . The holder 610 has a first guide slot 612 for placing film negatives (negative films), and two second guide slots 614 for placing slides (positive films). The crimping cover 620 includes a flat plate 622 to fix the positive film placed on the second guide groove 614 when the crimping cover 620 is fastened to the clamping seat 610; Compared with film negatives, slides are thicker, so a flange 624 is additionally provided on the crimping cover 620 so that when the crimping cover 620 is fastened to the clamping seat 610, it is fixed on the first guide groove 612. Film negatives. As shown in FIG. 4 , the flange 624 is used to fix the negative film, which will be described in detail later.

Firstly, how to place the positive film and the negative film on the clamping device 600 of the present invention will be described. Please refer to FIGS. 5 to 7 . FIG. 5 is a schematic diagram of the holder 610 , and FIGS. 6 and 7 are schematic diagrams of placing a positive film and a negative film on the holder 610 . It can be clearly seen from the auxiliary dotted line in FIG. 5 that since the size of the negative film is narrower than that of the positive film, two parts of the first guide groove 612 are extended outward on the clamping seat 610 to form two second guide grooves 614 . When the positive film is to be scanned, the positive film 692 can be placed in the second guide slot 614 to facilitate scanning, as shown in FIG. 6 . When the negative film is to be scanned, a long negative film 694 can be placed in the first guide groove 612 and fixed to facilitate scanning; and the clip holder 610 is further provided with two clips 634 for engaging one end of the negative film 694 , as shown in Figure 7.

The present invention uses the method of extending part of the first guide groove 612 outward to form the second guide groove 614, so that the first guide groove 612 and the second guide groove 614 can share part of the area to save the overall cost of the clamping device 600. area. Compared with the negative film holder 300 in the prior art, the holding device 600 of the present invention can place not only the positive film but also the negative film, and the size of the holding device 600 is only half of the negative film holder 300 . Compared with the film holders 100 and 200 of the prior art, the size of the holding device 600 is similar to that of the film holders 100 and 200, but the holding device 600 can hold positive and negative films at the same time, while the film holders 100 and 200 can only hold positive films Or negative film, so the clamping device 600 has a wide range of applications.

Regarding how to fix the positive film and the negative film on the clamping device 600 of the present invention, the present invention also has a simple and effective design. See Figures 8 through 10. FIG. 8 is a schematic diagram of the crimping cover 620 , and FIGS. 9 and 12 are side views of the crimping cover 620 . Since the thickness of the positive film (including the cardboard sandwiched around it) is greater than that of the negative film, the clamping cover 620 needs to be able to fix the positive film and the negative film respectively. The areas of the plate 622 and the flange 624 of the crimping cover 620 are shown in FIG. 8 . Please refer to Fig. 9, Fig. 9 is a side view in the direction of 9-9' in Fig. 8 . The plate 622 is used to hold the positive film, and the flange 624 can be used to hold the negative film. If the part A in FIG. 9 is enlarged and shown in FIG. 10 , it can be clearly seen from FIG. 10 that the thickness difference between the flat plate 622 and the flange 624 is different.

According to the above design of the clamping cover 620 and the clamping seat 610 , when the clamping seat 610 and the clamping cover 620 are combined, two spaces with different thicknesses can be generated, as shown in FIG. 11 . One space is for placing slides, and the other is for placing film negatives. Therefore, the clamping device 600 of the present invention can fix positive and negative films of different thicknesses therein.

In addition, since the thickness of the cardboard of the positive film is not exactly the same in production, there will be an allowable tolerance in the thickness of the production. Since the flat plate 622 of the clamping cover 620 of the clamping device 600 is fixed, sometimes due to manufacturing tolerances, the positive film may move when clamping the positive film. In order to avoid this problem, the flat plate 622 of the clamping cover 620 In addition, an elastic pressing arm 626 is added. Please refer to FIG. 12 . FIG. 12 is a schematic diagram of adding elastic pressing arms 626 to the pressing cover 620 . Next, please refer to FIG. 13 , which is a side view of the clamping device 600 with the elastic pressing arm 626 when the slide 692 is not placed. When the slide 692 is not placed, the elastic pressing arm 626 is in a relaxed state. Please refer to FIG. 14, when the slide 692 is placed in the second guide groove 614 and the clamping cover 620 is snapped onto the clamping seat 610, the elastic pressing arm 626 will be as shown in FIG. The thickness of the slide 692 is fixed, so the present invention can automatically adapt to the problem that the thickness of the cardboard of the positive film is different.

The clamping device 600 of the present invention also has an engaging member or a latch for engaging the clamping device 600 on the backlight board of the image processing device. Please refer to FIG. 4 again, the clamping device 600 has a latch 630 and two engaging parts 632 . Please refer to FIG. 15 , 700 is an image processing device.
