The present invention relates to a film with a film use discriminator attached to prevent reuse of the film used during photography by a small camera used in general.

In general, a simple portable camera is used to record important moments such as trips and events, and a film container in which a photosensitive material film is wound on a roll is opened on one side of the film chamber formed on both sides of the camera. Insert the film into the barrel, and the jaw of the film barrel and the handle shaft for winding the film is combined, then the film is inserted into the film winding lever shaft on the other side and the lid is used for taking a picture.

Here, the film is used by photography, and then the reel is rotated by rewinding the shaft of the knob which is retracted into the film roll case so that it is not exposed to light. Then, the film can is separated from the camera. After the film can not be separated from the unused film can not easily be used to mount the used film back to the camera to use the film already taken and the new film is taken over and the film can not be used.

In this way, by taking a picture of the film that has been recorded by mistake at the moment, the time of the shooting moment cannot be replayed once passed, and thus the same picture cannot be taken again, which causes a loss that cannot be evaluated with any value.

The present invention provides a film attached to the use of the film discriminator to determine whether the film is used or not by attaching the use of the film to prevent reuse in a conventional film canister to solve the above problems. I will.

Hereinafter, a configuration capable of achieving the above object will be described with reference to the accompanying drawings.

Typically, the lid [3] is fixed to one end of the tube [8], and the film [2] is wound on a roll [4] having shaft holes [6], [6 '] and support jaws [5], [5']. In the film container [1] formed by joining the roll [4] into the tube body [8] so that one end of the film [2] is exposed to the outlet opening [7] in a state of being in a closed state, and then fixing the lid [3 '] again. Rewinding the camera by attaching thin members [9] and [9 '] on top of the shaft holes [6] and [6'] having support jaws [5] at both ends of the roll [4] fitted to the rewind shaft [S] It is configured to be able to distinguish between the used film and the unused film to be broken when the shaft [S] is combined.

Referring to the effect of the present invention configured as described above in detail.

Since the rewind shaft [S] is moved up and down in the film chamber on the side where the film cylinder [1] is inserted into the film chambers of both ends formed in the film cylinder of the camera, the film cylinder [1] is combined, where the film cylinder [1] The members [9] and [9 '] are attached to the shaft holes [6] and [6'] on both ends of the roll [4]. have.

The film reel [S] of the camera is coupled to the shaft holes [6] and [6 '] of the roll [4] while the film barrel [1] is fitted, and the silver foil (aluminum foil) is placed on top of the shaft holes [6] and [6']. The rewind axis [S] of the camera is the shaft hole [6], [6 '] of the film barrel [1], depending on the type of camera, with the thin and easily damaged members [9] and [9'] attached. ] Is coupled to one end.

That is, the members [9] and [9 '] attached to the periphery of the shaft holes [6] and [6'] at both ends of the roll [4] are damaged by the rewind shaft [S] of the camera and the jaws [5] and [5 ']. And one side of film [2] to the other film chamber where the film taken by the camera is wound in the state of being fitted into the groove (not shown) of the rewinding axis [S], and the rear lid of the camera is closed and the film [2] is rolled. As it is released from [4], the film winding lever is turned to enable taking a picture.

Once shooting is complete, the film rewind axis [S] is rotated in reverse to open the rear lid of the camera and remove the film barrel [1] while the film [2] is wound into the film barrel [1] to prevent exposure. Since the members [9] and [9 '] are broken by the rewind shaft [S] of the camera, it is easy to confirm that the members [9] and [9'] are damaged.

In other words, it is possible to easily determine whether the film is used without preventing the use of the camera by attaching the simple members [9] and [9 '], thereby preventing overshooting.

Claims (2)

Typically, the lid [3] is fixed to one end of the tube [8], and the film [2] is wound on a roll [4] having shaft holes [6], [6 '] and support jaws [5], [5']. In the film container [1] formed by joining the roll [4] into the tube body [8] so that one end of the film [2] is exposed to the outlet opening [7] in a state of being in a closed state, and fixing the lid [3 '] again. Rewinding the camera by attaching thin members [9] and [9 '] on top of the shaft holes [6] and [6'] having support jaws [5] at both ends of the roll [4] fitted to the rewind shaft [S] The film with the use discrimination device, characterized in that broken when the shaft [S] is coupled. 2. The rewind shaft [S] of the camera according to claim 1, wherein a thin subfold [9] is attached to an upper portion of the shaft hole [6] having a supporting jaw [5] at one end to a roll [4] fitted to the rewind shaft [S] of the camera. ] Is attached to the film used to determine whether the device is characterized in that when broken.
