KR200164620Y1 - Developed device that make it possible to develope used parts of film and to recycle rest of the film - Google Patents

Abstract

(1) Technical Field

Film cartridge manufacturing and developing field for photography

(2) Purpose of devising

Currently developed camera film is developed when the entire film is not used up, and the unused part is lost during the development of the used part, and the unused part of the entire film cannot be used again. There is an absurdity to delay the development until the user runs out of film or give up the unused portion of the film. The advantage is improved so that after only part of the film is used, only the used part is developed and the unused part can be reused later.

(3) constitution

Depending on the direction and degree of rotation of the film cartridge reel, the control film that stores the film movement length, the attachment ring for fixing the control film to the rotating reel, the expansion ring for installing the attachment ring, and the removable mounting on the film cartridge The main board is the main component.

(4) effect of design

This device (design) is a film of the longest length of the film that has been pulled out of the film cartridge by a simple device operation after a few times the film is taken out of the film cartridge and then rewound into the reel and then reinserted into the cartridge. Only the cartridges can be pulled out of the cartridge, and more can not be pulled out of the cartridge, it can be used to distinguish between the part used in the actual film and the unused part of the film.

Description

Improved removable device that enables film part development and recycling {developed device that make it possible to develope used parts of film and to recycle rest of the film}

Conventional film cartridges have a simple structure consisting of an outer body acting as a dark room, a reel winding the film, and a film, and perform only a simple operation of moving the film into or out of the cartridge by the rotation of the reel. Accordingly, if the entire film is not exhausted during the photography process, the film is divided into the used part and the unused part, but the two parts cannot be distinguished, so only the used part is developed and the unused part is recycled. It's not easy to work.

Professional photographers and some laboratories use manual methods to separate only the parts of the film that are actually used, but they are less accurate and difficult to process in large quantities.

The film cartridge and the development method using the same which eliminate the problems of the existing fields are filed with a utility model (application number: 20-1999-0007762, 20-1999-0009976) and a patent (application number: 10-1999-0016529), respectively. The audit has been filed.

In the case of the previously applied advanced film cartridge (Application No. 20-1999-0009976), the attachment ring and the connecting ring, which are parts for fixing the control film to the rotating wheel of the film magazine, are not only complicated and manufactured. Due to the weak force that the ring tightens the rotating wheel of the film magazine, a malfunction such as the attachment ring slips in the process of rotating the wheel of the film magazine is expected, making it easier to manufacture than the attachment ring and the connecting ring. Improved to ensure proper attachment.

Since the present invention is an improvement of the previously applied improved film cartridge (Application No .: 20-199-0009976 or earlier application), only the improved part of the existing application will be described in comparison with the existing application.

1. Main Board: [Fig. 1], [Fig. 3] are main boards of the present application. Compared with the main board of the present application, the main board of the improved design of [FIG. 2], [FIG. 4] was two in this application to install the expansion ring according to the change of the shape of the expansion ring in the present invention. The grooves (1 and 1 in Fig. 1) were changed to four. The added two grooves are indicated by 1 and 2 of [Fig. 2].

2. Attachment ring: Since the attachment ring of the previous application is made of soft and elastic plastic material, there is a problem that it does not attach strongly to the rotating wheel of the film magazine. Use soft and elastic rubber to reinforce. The shape of the improved attachment ring is shown in [6] and [9], and the size of the circle of the attachment ring should be smaller than the radius of the rotating wheel of the film magazine. In order to be able to hook the extension ring, the force of the attachment ring shall increase in size by a rectangle with four legs of the extension ring as the vertex.

3. Expansion ring: Compared with the expansion ring of the existing application, the improved expansion ring is the same material, but four legs and the extension ring of the existing application (parts 1 and 2 of FIG. 9) to hold the attachment ring. In the improved system, however, this part is absent because the attachment ring is hung on the extension ring.

4. Connection of attachment ring and extension ring: The improved attachment ring is a rubber that stretches to a certain degree when a force is applied, and the improved extension ring is designed with four legs. Stretch the ring and hang it on the leg of the extension.

5. How to install the attached ring and extension ring on the motherboard

The improved motherboard has four grooves for installing an improved expansion hook. Therefore, this groove may be provided with an extension ring connecting the attachment ring as shown in [14] and [15]. At this time, since the square caused by the attachment ring on the four legs of the expansion ring includes a circle (1 in Fig. 4) in the center of the motherboard, the expansion ring or the attachment ring in the process of connecting the device to the film magazine later. This will not be in the way.

Parts other than what has been described above are the same in form, function and installation method with the existing application.

The connection and adhesiveness between the attachment ring and the rotating wheel of the film magazine become stronger, which is a problem that may occur in the previously applied advanced film cartridge (application number: 20-1999-0009976), so that the rotational force of the rotating wheel of the film magazine is directly applied to the attachment ring. The difference between the length of the film and the length of the transferred control film can be eliminated from the film magazine, which may occur during the transfer of the control film.

Claims (1)

It consists of control tape, improved extension ring, improved attachment ring, and improved main board, and when it is attached to the film cartridge for camera, the length of the film is taken out of the cartridge after rewinding and rewinding of the cartridge. Removable device that allows only as much film to exit the cartridge and prevents further film from exiting the cartridge
