Background Art

[0002] A copy photographing dark box is a structural device for blocking light, mainly used to solve problems such as virtual light and reflection during photographing to ensure clear imaging. This device is very useful in photography and video shooting, especially in situations where light interference needs to be reduced, such as when photographing documents, goods or other occasions requiring high-quality imaging.

[0003] The existing copy photographing dark box technology generally includes the following characteristics:

[0004] Structural design: Copy photographing dark boxes usually adopt a foldable structural design for easy carrying and use. They are usually made of soft materials (such as cloth or plastic), and sometimes are equipped with an internal support structure to ensure stability. Internal reflective material: To reduce light reflection, non-reflective materials such as black flannelette and light-absorbing cloth are usually used inside the copy photographing dark box to ensure that light does not generate excessive reflection inside. Side openings: To easily place the object to be photographed inside the dark box for photographing, the copy photographing dark box usually has one or more side openings for convenient placement of items and photographing. Adjustability: Some copy photographing dark boxes have adjustable openings and support structures to adapt to different sizes and shapes of photographed objects to ensure flexibility and applicability. Light filling: Some copy photographing dark boxes are also equipped with a light source to provide uniform and soft light to ensure clarity of the photographed object. Summary of the Utility Model

[0005] In order to solve the problem that virtual light is easily generated during the copy photographing of old photos or physical photos, resulting in unclear copy images or photos, the present application provides an adjustable copy photographing dark box without virtual light. After the applicant designed and produced samples and actually inspected the effects, it was determined that it can provide a uniform light environment. During the process of photo copy photographing, no virtual light or reflection will be generated, and old photos or physical photos can be clearly converted into electronically stored photos for easy preservation, so that old photos can be further optimized, preserved, copied and reused. The utility model also provides a light-transmitting platform for facilitating the viewing of light-transmitting film images such as negatives and X-ray films.

[0006] In order to achieve the above object, the technical solution adopted by the present application is as follows:

[0007] An adjustable copy negative box without virtual light, comprising a hollow outer shell, wherein a light-emitting unit for providing uniform light is arranged inside the outer shell, the light-emitting unit is located at a position close to the bottom on the inner wall of the hollow of the outer shell, and a support plate for placing the copied photo is detachably arranged at the bottom of the outer shell; a focusing mechanism capable of sliding up, down, left and right is arranged at the top of the outer shell, and the focusing mechanism has a window through which light passes.

[0008] In order to enable shooting devices with different focal lengths to focus freely, so as to obtain a clearer copied image, preferably, the focusing mechanism includes a plurality of support columns slidably arranged in the outer shell in the up-and-down direction of the outer shell, a sleeve for supporting the panel is sleeved on any one of the support columns, and the sleeve is provided with an opening or no opening; any one of the support columns is detachably connected with a fastener, a panel for supporting the shooting device is installed between the upper end face of the support column and the fastener, and a first window for light to pass through is arranged on the panel. The function of the support column is to play a role in up-and-down adjustment, so as to change the linear distance between the panel and the photo located on the support plate, achieving the function of adjusting the focal length. In order to make the shooting device, such as an existing smart phone, more stable during shooting, the relative position of the panel and the outer shell can be fixed by clamping or sleeving the sleeve on the support column, which is more conducive to shooting. Among them, the length of the sleeve can be freely set, and usually multiple models with different lengths can be set according to the actual application scenario to facilitate replacement during actual use. Regarding the structure of the sleeve, an open sleeve structure or a non-open sleeve structure can be adopted. The advantage of the open sleeve is that it is not necessary to completely pull out the support column, and it can be directly clamped and installed; on the contrary, for the non-open sleeve structure, the fastener needs to be removed or the support column needs to be completely pulled out, and then inserted from any end of the support column, and the convenience of such operation is worse.

[0009] In order to be compatible with the camera positions of different shooting devices, preferably, strip-shaped holes are arranged at corresponding positions of the panel and the support columns in the left-right / front-back direction, and the panel can reciprocally slide along the length direction of the strip-shaped holes relative to the fastener. The panel can be adjusted left and right and / or front and back relative to the outer shell, so as to align the camera with the middle of the photo to be taken.

[0010] In order to further expand the convenience of plane position adjustment, preferably, a sliding piece for adjusting the position or size of the window is further slidably arranged on the upper end face / inside / lower end face of the panel, and a second window for light to pass through is arranged on the sliding piece.

[0011] In order to facilitate stable sliding and avoid tilting when sliding in a certain direction, preferably, a chute structure for restricting or constraining the sliding track of the sliding piece is arranged on the panel.

[0012] The utility model also provides another structural setting for application scenarios, so as to facilitate viewing of films, X-ray films or similar light-transmitting imaging bodies. Preferably, the bottom of the outer shell is also detachably provided with a light-transmitting cover plate, the hollow inner wall of the outer shell is provided with a step, and a diffuse reflection bottom plate is placed on the step. The hollow inner wall of the outer shell, the diffuse reflection bottom plate and the light-transmitting cover plate surround and form a light mixing cavity A. The light-emitting unit is installed on the hollow inner wall of the outer shell and is located between the diffuse reflection bottom plate and the light-transmitting cover plate. Since the light-transmitting cover plate can provide uniform light, images of light-transmitting materials such as films can be effectively and clearly viewed.

[0013] In order to simultaneously meet the requirements of removability and good light transmittance of the light-transmitting cover, preferably, the light-transmitting cover includes a cover frame, a snap-fitting ridge fixed or integrally connected to the cover frame for engaging with the hollow interior of the outer shell, and a light-transmitting plate installed in the cover frame for uniformly transmitting light.

[0014] In order to provide more uniform light and better avoid the problems of virtual light and concentrated reflection, preferably, at least one surface of the light-transmitting plate is frosted or the light-transmitting plate has a plurality of unevenly or evenly arranged reflective particles inside.

[0015] Still further preferably, the light emitting unit is an LED light box / light strip with uniform light.

[0016] According to the requirements of the shooting application scene, preferably, the light emitting unit is arranged on two opposite sides or four sides of the hollow inner wall of the outer shell.

[0017] Beneficial effects:

[0018] 1. The utility model can construct a space with uniform light and closed, so that the light on the surface of the photo to be taken is uniform, and no local virtual light and light concentration will be generated during the copying, which will lead to the problem of reflective imaging distortion, and a clear copy electronic image can be obtained.

[0019] 2. The utility model can also provide a light-transmitting platform with uniform light. Placing a light-transmitting film on the light-transmitting plate can clearly identify the details of the film, X-ray film, and MRI film image, which is more conducive to viewing.

[0038] Embodiment 1:

[0039] This embodiment provides a virtual-light-free adjustable photographing negative box for illustrating the structural principle and usage mode when photographing photos. Refer to the attached Figures 6 - 10As shown, it includes a hollow outer shell 1, and a light-emitting unit 3 for providing uniform light is arranged inside the outer shell 1. The light-emitting unit 3 is located at a position close to the bottom on the inner wall of the hollow of the outer shell 1. A support plate 8 for placing the retaken photo is detachably arranged at the bottom of the outer shell 1. A focusing mechanism capable of sliding up, down, left and right is arranged at the top of the outer shell 1, and the focusing mechanism has a window for light to pass through. When retaking a photo, it is very simple. Just place the photo to be retaken on the inner side of the support plate 8, then install the support plate 8 at the bottom of the outer shell 1, turn on the light-emitting unit 3 so that there is uniform light on the photo to be retaken for easy shooting, and then place the shooting device on the focusing mechanism above the outer shell 1. As Figure 10 shown, by adjusting the position of the focusing mechanism, the camera can be vertically aligned with the middle position of the photo for shooting. In this embodiment, the directions of up, down, left, right, front and back are as Figure 6 shown, where Figure 7 in the X-axis direction is from front to back, the Y-axis direction is from right to left, and the Z-axis direction is from bottom to top.

[0040] In this embodiment, in order to satisfy the requirement that shooting devices with different focal lengths can focus freely, so as to obtain a clearer copy image, the focus adjustment mechanism includes a plurality of support columns 12 slidably arranged in the outer shell 1 in the up-down direction, any of the support columns 12 is provided with a sleeve 13 for supporting the panel 6, and the sleeve 13 is provided with an opening or a non-opening setting; any of the support columns 12 is detachably connected with a fastener 9, and a panel 6 for supporting the copy device is installed between the upper end surface of the support column 12 and the fastener 9, and the panel 6 is provided with a first window 61 for light to pass through. The function of the support column 12 is to adjust up and down, thereby changing the straight-line distance between the panel 6 and the photo located on the support plate 8, so as to achieve the function of adjusting the focal length. In order to make the shooting device, such as the existing smart phone, more stable when shooting, the relative position of the panel 6 and the outer shell 1 can be fixed by clamping or sleeved on the support column 12 by the sleeve 13, so as to be more conducive to shooting. Among them, the length of the sleeve 13 can be freely set, and usually multiple models of different lengths can be set according to the actual application scenario to facilitate replacement during actual use. The structure of the sleeve 13 can adopt an open sleeve structure or a non-open sleeve structure. The advantage of the open sleeve is that it does not need to completely pull out the support column 12, and it can be directly snap-fitted and installed; on the contrary, the non-open sleeve structure requires the fastener 9 to be removed or the support column 12 to be completely pulled out, and then inserted from any end of the support column 12, so the convenience of operation will be worse. It is worth noting that the cross-sectional shape of the support column 12 is preferably a regular polygon, but other cross-sectional shapes are also acceptable, but it is preferably that the support column 12 is not rotatably connected to the outer shell 1, otherwise, when installing the fastener 9, it is not convenient for one-handed operation.

[0041] In order to be compatible with the camera positions of different shooting devices, in this embodiment, the panel 6 is provided with a strip hole 62 arranged along the left-right / front-back direction at a position corresponding to the support column 12, and the panel 6 can slide back and forth along the length direction of the strip hole 62 relative to the fastener 9. The panel 6 can be adjusted left-right and / or front-back relative to the outer shell 1, so that the camera can be aimed at the middle of the photo to be taken.

[0042] In order to further enhance the convenience of plane position adjustment, in this embodiment, a slide plate 7 for adjusting the window position or size is slidably provided on the upper end surface / interior / lower end surface of the panel 6, and a second window 71 for light to pass through is provided on the slide plate 7. Figures 6 - 7The structure shows a slide plate that is set inside the panel 6 and slides in the front-to-back direction; of course, this is only one embodiment, and the installation direction of the slide plate 7 can also slide in the left-right direction. Similarly, the slide plate 7 can be slidably set on the upper end surface or the lower end surface, that is, set on the top surface or the bottom surface of the slide plate 7, and the sliding of the slide plate 7 can be limited by the protruding slide groove structure 63. In order to facilitate stable sliding and avoid tilting when sliding in a certain direction, the panel 6 is provided with a slide groove structure 63 for limiting or constraining the sliding trajectory of the slide plate 7. In order to facilitate the twitching adjustment of the slide plate 7, one or both ends of the slide plate 7 are provided with an anti-slip structure 72 for easy gripping or holding, such as Figure 6 When the camera is placed on the panel 6 for shooting, the hollow structure of the outer shell 1 forms a closed light mixing cavity B14, and then the camera is aimed at the photo at the bottom of the light mixing cavity B14 to complete the copying.

[0043] Embodiment 2:

[0044] The utility model also provides another structural setting for application scenarios, so as to facilitate viewing of films, X-ray films or similar light-transmitting imaging bodies. In this embodiment, see Figures 1 - 5 As shown, the bottom of the outer shell 1 is detachably provided with a light-transmitting cover plate 2, the hollow inner wall of the outer shell 1 is provided with a step 11, and the diffuse reflection bottom plate 4 is placed on the step 11. The hollow inner wall of the outer shell 1, the diffuse reflection bottom plate 4 and the light-transmitting cover plate 2 surround and form a light mixing cavity A5, and the light-emitting unit 3 is installed on the hollow inner wall of the outer shell 1 and is located between the diffuse reflection bottom plate 4 and the light-transmitting cover plate 2. Since the light-transmitting cover plate 2 can provide uniform light, images of light-transmitting materials such as film can be effectively and clearly viewed.

[0045] In order to satisfy both the detachability and good light transmittance of the light-transmitting cover plate 2, in this embodiment, see Figure 5 As shown, the light-transmitting cover plate 2 includes a cover plate frame 21, a snap-fitting ridge 22 fixed or integrally connected to the cover plate frame 21 for engaging with the hollow interior of the outer shell 1, and a light-transmitting plate 23 installed in the cover plate frame 21 for uniform light transmission.

[0046] In order to provide more uniform light and better avoid the problems of vignetting and concentrated reflection, in this embodiment, see Figures 1 - 3As shown, at least one surface of the light-transmitting plate 23 is frosted or there are multiple reflective particles unevenly or evenly arranged inside the light-transmitting plate 23. The purpose of adopting this structural setting is to generate more diffuse reflection, so that the light at any position in the light mixing cavity A5 comes from different directions, thereby making the light transmitted from the light-transmitting plate 23 more uniform. Further, the light-emitting unit 3 is an LED light box / light strip with uniform light. According to the requirements of the shooting application scenario, the light-emitting unit 3 is arranged on the opposite sides or around the hollow inner wall of the outer housing 1.

[0047] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
