Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a camera using a roll film, which can cut and take out the film up to the photographed portion even during use and can photograph the remaining film. is there.

[0002]

[Prior art]

 Conventionally, in a camera using a roll film, it has been usual to use a film capable of taking a large number of images such as a film for taking 24 images and a film for taking 36 images. Especially in a small size camera, the roll film was used in a half size and even used as a film for taking 48 or 72 sheets.

For photographers, when they want to develop and print before the end of filming all the films, they have to rewind the whole film and develop and print the unused part. .

However, it is not economical to develop and print without using the unused film, and a method has been sought to develop and print only the filmed part and to film again with the remaining film. Was there.

[0005]

[Problems to be solved by the present invention]

 Therefore, the present invention provides the following points as problems to be solved. Use a camera that has a mechanism that allows the roll film to be cut during use. Use a camera that has a mechanism to take out the film only from the shooting part. A camera that can shoot with the rest of the film.

[0006]

[Means for solving the problem]

 Therefore, in order to solve the above problems, the present invention forms a cutter sliding groove in a structure in which light does not leak perpendicular to the film passing position of the lid immediately before the shooting position in the film advancing direction, and the sliding groove is formed inside the lid. A film cutter that slides along and is operated by a lever provided on the outside of the lid is used, and the film winding section inside the camera body is a detachable closed cassette with a film insertion port The camera body on the bottom is a lid for opening / closing the cassette, and the cutter is operated while the film is in use to wind and take out the taken film in the closed cassette. Is.

【Example】

 An embodiment of the present invention will be described below. FIG. 1 is a rear view of a camera according to the present invention. Reference numeral 1 in the figure denotes a camera body, and although not shown, the front surface of the camera body 1 is no different from a normal camera. Reference numeral 4 in the drawing denotes a lid, and the lid 4 is provided with a cutter sliding groove 6 in addition to the ordinary constituent elements. In the figure, 5 is an opening / closing lever of the lid 4, and 9 is a film winding dial.

FIG. 2 is a view showing the inside of the camera body 1 with the lid 4 opened, and the cutter sliding groove 6 is slightly wider than the film width at the film passing position of the lid 4 immediately before the shooting position in the film traveling direction. It is long and formed vertically. In addition, it is preferable that a cutter passage groove 17 is formed inside the camera body 1 at a position corresponding to the cutter slide groove 6 with the lid 4 closed.

A cutter blade 7 is positioned on the side of the camera body 1 in the sliding groove 6, a cutter lever 8 is attached to the outside of the lid body 4, and the cutter lever 8 operates. . A brush portion 11 is formed so that the sliding groove 6 does not transmit light. The cutter blade 7 and the brush portion 11 are shown in detail in FIG.

In FIG. 2, reference numerals 13, 14, 15, 16 denote film feed gears which rotate in association with the rotation of the winding dial 9 and which are arranged so as to mesh with the film halflation 18. There is. The film feed gears 13 and 14 are provided above and below the unused film side by the cutter passage groove 17, and the film feed gears 15 and 16 are provided above and below immediately before the film winding section 2.

In the film winding section 2 inside the camera body 1, a hermetically sealed detachable film winding cassette 10 is arranged. The closed cassette 10 has a film insertion opening 12 formed with a brush portion or the like for preventing the entry of light.

Although not shown, a rotary shaft that is rotated by the rotation of the winding dial 9 is provided inside the closed cassette 10, and claws for halflation are formed above and below the rotary shaft. Has been done. Therefore, by rotating the take-up dial 9, it is possible to hang the claws on the half and wind the film into the closed cassette 10. The closed cassette 10 itself does not rotate.

An openable / closable cassette take-out lid 3 is formed below the film take-up section 2 on the bottom of the camera body 1.

[0014]

【effect】

 Hereinafter, the effects of the present invention will be described together with the usage state. To mount the film on the camera, mount the closed cassette 10 on the film winding unit 2, insert the leading end of the film into the film insertion port 12 of the closed cassette 10, feed the half gear 18 of the film, feed gears 13, 14, 15 and 16 are meshed with each other, and the winding dial 9 is rotated to mount the film.

When taking a picture, there is no difference from a normal camera, and if it is desired to finish at a desired position in the middle of the film after the picture is taken, the cutter lever 8 of the camera back cover 4 is pushed downward. This causes the cutter blade 7 to cut the film.

After that, when the winding dial 9 is turned, the unused film is fed to the photographing location by the gears 13 and 14, and the photographed film is completely wound into the closed cassette 10.

At the time of taking out the closed cassette 10, the cassette take-out lid 3 on the bottom surface of the camera body can be opened to take out the closed cassette 10 containing only the photographed film. At this time, a new closed cassette 10 is attached for the next shooting.

As described above, when developing and printing before the end of the film, do not rewind in the middle of the film and do not develop and print the unused part, but cut only the shooting part. It became an economical camera that can be taken out, developed, and printed, and even after cutting, you can continue shooting with unused film.
