Description

[Detailed explanation of the invention] This invention consists of removing one side cover of the cartridge,
This invention relates to an improvement in a cartridge side cover removal device for taking out undeveloped photographic film from the cartridge.

One way to take out photographic film from a cartridge for development is to remove one side cover of the cartridge and take out the photographic film together with the spool. This method has a groove for guiding the film drawer so that the cartridge, which has a generally circular cross-sectional shape that protrudes only at the film drawer, can be inserted without rotating. , a cartridge receiver having a through hole with a groove for guiding the film drawer, which is provided with a fixing protrusion or a fixing claw that abuts one side edge of the film drawer to stop and fix the cartridge; Insert the cartridge into the grooved through-hole for guiding the film drawer, push the spool shaft of the cartridge from the starting end side with the pushing rod, and in the middle of this pushing, one edge of the film drawer of the cartridge will pull out the film. The front side cover of the cartridge is removed by the pushing force after it hits a fixing protrusion in the guide groove or a fixing claw. In some cases, this film drawer part may be crushed, and the cartridge cannot be stopped by the fixing protrusion or fixing claw, making it impossible to remove the side cover, and making it difficult to dispose of the cartridge. It was often hot.

In view of the above-mentioned circumstances, the present invention has developed a flat surface that includes the axis of the grooved through-hole for guiding the film drawer section, with the support shaft as the center, instead of the conventional fixed protrusion or fixed claw. The film drawer part is biased to be constantly exposed in the film drawer guide groove so that the claw part can rotate along the film drawer part, and the claw part abuts one side edge of the film drawer part near the end of the through hole. Not only that, but also the cartridge retaining claw plate stops rotating when the claw comes closest to the axis of the through hole, so that the claw of the cartridge retaining claw plate can hold the cartridge tightly. As long as the cartridge hits the one side edge of the film drawer, the claw part will move the one side edge of the film drawer depending on the degree of advance of the cartridge, which is pushed forward on the forward path of the pushing rod. Since the cartridge slides in the axial direction of the cartridge along the axial direction, the degree of abutment and biting is gradually increased on one edge of the cartridge without slipping off. This type of side cover removal machine and side cover removal device for cartridges of this type are designed to ensure that the side cover is securely stopped at a predetermined position within the through hole, firmly supported and held, and that the side cover can be removed reliably. This invention has made it possible to provide a cartridge side cover removal device which can eliminate the drawbacks and deficiencies of the prior art.The present invention will be explained in detail below with reference to the illustrated embodiments.
