Description

Technical Field

[0001] This utility model relates to the field of film camera technology, and in particular to an instant camera back structure suitable for medium format film cameras. Background Technology

[0002] Compared to instant cameras, traditional film cameras have a significant disadvantage: the image quality and effect can only be confirmed after the film is developed; developing photos is time-consuming and cumbersome, requiring special equipment and facilities. By using instant developing paper (hereinafter referred to as "Instant Photo Paper"), instant cameras can achieve instant development and no-processing required for the image. Currently, most instant cameras on the market do not have excellent image quality, and high-quality film cameras cannot directly take instant photos. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Polaroid back structure suitable for medium format film cameras.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes an instant film processing module and a front panel. The front panel is provided with an upper and lower latch structure for connecting with a format film camera in the Hasselblad V system. A manual switch is provided on the left side of the upper latch, which can be manually controlled to slide the upper latch left and right to complete the installation and removal of the instant camera back. The instant photo paper processing module has a rear cover at its rear end. After opening the rear cover, instant photo paper can be inserted. The inner left end of the instant photo paper processing module has a drive motor. The output end of the drive motor is fixedly connected to a worm gear. The outer side of the worm gear is meshed with a worm wheel. The outer side of the worm wheel is meshed with a reduction gear set. The outer side of the reduction gear set is meshed with a transmission gear set. The upper end of the transmission gear set is meshed with a photo paper drive gear set. The photo paper drive gear set is equipped with a photo paper drive roller. The lower end of the transmission gear set is meshed with a rotating disk. The rotating shaft on the rotating disk is rotatably connected to a connecting rod. The other end of the connecting rod is connected to a push frame. A photo hook is installed on the push frame by screws.

[0005] Preferably, the front panel is provided with an upper and lower latch structure for connecting to the format film camera in the Hasselblad V system. The upper latch has a manual switch on its left side, a sliding groove, and a spring connected to it.

[0006] As a further step of the above technical solution: the upper buckle is provided with a sliding groove, which limits its movement to a fixed range in the left and right directions, and the connected spring can make it automatically reset and lock onto the camera.

[0007] Preferably, a drive motor is provided on the inner left end of the instant photo paper processing module, the output end of the drive motor is fixedly connected to a worm gear, the outer side of the worm gear is meshed with a worm wheel, and the outer side of the worm wheel is meshed with a reduction gear set.

[0008] As a further step of the above technical solution: the drive motor is periodically energized by circuit control, and the torque is amplified through the structure of worm gear and reduction gear, thereby extruding the photographic paper.

[0009] Preferably, a rotating disk is engaged at the lower inner side of the instant photo paper processing module, a connecting rod is rotatably connected to the rotating shaft on the rotating disk, and a push frame is connected to the other end of the connecting rod. A photo hook is installed on the push frame by screws.

[0010] As a further step in the above technical solution: the rotation of the rotating disk drives the linkage structure to transmit power to the push frame. The push frame is installed in the slide groove and is limited to sliding up and down. Each time the rotating disk rotates once, the push frame slides from the lowest point to the highest point and then rotates back to the lowest point to reset. The photo hook installed on the push frame hooks the instant photographic paper at the lowest point and then pushes it to slide upward, feeding it into the photo conveyor shaft driven by the photo paper drive gear set for extrusion.

[0011] This utility model has the following beneficial effects:

[0012] Compared to existing technologies, this instant camera back structure, suitable for medium format film cameras, allows for quick and easy connection to a Hasselblad V-system medium format film camera via upper and lower snap-fit ​​structures on the front panel. A drive motor, worm gear, worm wheel, and gear set electrically extrudes the instant film and forms an image, providing a physical photograph immediately after shooting. This instant camera back simplifies the integration of professional cameras and instant cameras, reduces production costs, and provides users with a cost-effective professional imaging solution. The widespread application of this technology is expected to further integrate the professional photography market and the instant imaging market, offering users more diverse choices.
