Description

[Detailed description of the device]

[Field of Industrial Application] The present invention relates to an improvement of a disposable camera, which is pre-loaded with a film in the manufacturing process of the camera and is sold, and after the purchase, it is possible to take a picture immediately, The present invention relates to a reusable single-use camera that allows a photographer to take out and exchange a film, which can only be taken out in places, etc.

[Prior Art] Conventional simple commercially available cameras have a very simple housing structure made of plastic resin or the like for the purpose of low price. 4A, 4B, and 4C, there is no need for a function to take a picture with certainty. Therefore, as shown in FIGS. 4A, 4B, and 4C, the imaging lens 1, the window 2, the shutter button 3, the film winding Knob 4, film counter window 5, strobe light emitter 6, flash lamp 7, finder eyepiece window 8 and all of the basic functions of the camera, and are made of synthetic resin such as plastic. It is compactly mounted in the camera housing 10, and the open / close function of the back cover used in a normal camera is abolished, and the simplification is achieved. The outer surface of this disposable camera was covered with a paper cover 9 shown in FIG. 4 (C), and the surface of which the colors and patterns were printed was commercially available.

Due to such a simple structure, the camera housing is not a structure in which the photographer can open the back cover to exchange the film, but disassembles the camera housing at a specific place such as a dark room in the developing room to remove the film. I had to take it out and develop it. Therefore, when the photographer has finished shooting one film loaded in the camera, he must send it to the photo lab, including the camera itself, and request it for development. There was no means outside of buying a single-use camera.

[Problems to be Solved by the Invention] Recently, as seen in the enactment of the PL Law, the public has a harsh eye on producers, and in addition, there is a strong criticism of disposables due to the waste disposal problem in each municipality. As it is becoming a world in which reuse must be considered, it is becoming increasingly difficult to produce and sell disposable cameras forever. Therefore, it was desired to develop a camera that allows the photographer to exchange and load the finished film without sacrificing the simple camera function used in the disposable camera.

[Means for Solving the Problems] According to the present invention, an opening for replacing and loading a film is provided on the back surface of a camera housing, and the camera housing and the back cover of the opening can be opened and closed by a hinge. A camera step is provided on the side of the camera housing over the entire circumference of the opening, and a peripheral rising portion is also provided on the side of the back cover over the entire circumference to optically seal the camera housing and protect it from outside light. Prevent light leakage. For fixing the back cover, a semi-cylindrical fixing tool protrusion is attached to the housing side, and a fixing tool provided with a recess that engages with this semi-cylindrical fixing tool protrusion is attached to the back cover side. Fix your body.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a reusable single-use camera according to an embodiment of the present invention when a back cover of a camera is opened. FIG. 2 is a partial view of a portion for fixing the back cover of the reusable disposable camera according to the embodiment of the present invention. FIG. 3 is a sectional view of the reusable single-use camera according to the embodiment of the present invention taken along the line AA '.

The reusable single-use camera according to the present invention is based on the conventional single-use camera shown in FIG. 1, and has an opening at the back of the camera to provide a back for film replacement and loading. The lid 28 is attached to the camera housing 30 so as to be openable and closable by a hinge 29, and can be optically sealed and fixed by a fixture 26 and a fixture protrusion 27.

Since the camera shown in FIG. 1 has a basic structure of a conventional disposable camera, the lens 1, the fiber 2, and the strobe light emitter 6 are not shown in the drawing, but are provided on the front surface of the camera housing 30. ing. Other basic functions required for the camera include a shutter button 3 for opening and closing the shutter, a film winding knob 4 for winding the film after shooting one frame at a time, and counting the number of film shots. A window 5 for displaying the number of remaining films, a strobe flash lamp 7, a window for viewing the eyepiece 8 for displaying a shooting range, a film winding roller 22 for winding a film already photographed, a film feeding section 23 for feeding out an unphotographed film, a film. The sprocket 24, etc. that meshes with the above-mentioned perforation and sends out one frame at a time is incorporated in the plastic resin camera housing 30. The sent back film is attached to the back cover 28 that is openably and closably attached to the opening. The back cover retainer 25 is attached to the flat surface so as not to hinder the taking of photographs.

Since the conventional disposable camera does not have a film exchange function, the camera housing can be configured relatively simply, or the camera of the present invention is provided with a back cover in order to provide a film exchange function. However, it must be opened and closed so that the film can be taken out and exchanged and loaded, so that the structure is complicated.

Since an opening is provided on the back surface of the camera housing 30 and the film is exchanged and loaded from this portion, a housing step portion 31 is provided around the opening around the opening as shown in FIGS. 2 and 3. The peripheral rising part 32 of the back cover 28 is fitted over the housing step 31 to prevent outside light from leaking into the camera housing 30. The inner surface of the camera housing 30 and the inner surface of the back cover 28 are matte black to prevent diffuse reflection of leaked light.

In order to fix the camera housing 30 and the back cover 28, a semi-cylindrical fixture protrusion 27 is provided on the camera housing 30 side, and this semi-cylindrical shape is provided on the back cover 28 side. There is a fixture 26 that has elasticity and a semi-cylindrical recess for overcoming the fixture protrusions 27 and fitting the fixture protrusions 27 to fix the back cover 28, both of which are made of resin such as plastic. Then, the back lid 28 is fixed over the semi-cylindrical fixing protrusion 27 by using elasticity.

In the conventional disposable camera, the outer circumference of the camera is covered with a paper cover 9 to improve the appearance and enhance the commercial value. However, in the camera according to the present invention, the back cover 28 is opened and closed to exchange the film. Since the paper cover 9 cannot be used to decorate the outer periphery of the housing, the resin itself forming the housing 30 must be colored and decorated to improve the appearance and retain the commercial value.

As discussed above, the reusable single-use camera according to the present invention is based on the single-use camera that has hitherto been commercially available, and only the rear part of the reusable camera is changed to suit the application. Therefore, it is not a major change, the change cost is small, and there are few factors for price increase.

[Effect of the Invention] As described in detail above as the embodiments, the reusable single-use camera according to the present invention has various advantages. Since the back cover of the camera can be freely opened and closed, the photographer can exchange and load the film after shooting, so if you have finished shooting the loaded film as before, return it to the laboratory including the camera. This saves you the trouble of doing it and saves unnecessary expenses such as having to purchase and shoot a new disposable camera. Also, since the used camera itself can be reused, it is possible to prevent the generation of dust and to save resources, and because it follows the design concept of conventional disposable cameras, it is generally inexpensive and saves money.
