Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a disposable film-integrated camera that has various functions necessary for photographing integrated into a main body preloaded with film. .

[Conventional technology]

Generally, this type of film-integrated camera is designed to break the camera itself and take out the film when all the frames of the preloaded film have been photographed and developed. Each film is disposable after each use.

[Problem that the invention is trying to solve]

The conventional cameras mentioned above are destined to be as simple and inexpensive as possible while maintaining the photographic function. However, with the spread of disposable cameras, there has been a desire for more sophisticated and diversified photographic functions, such as telephoto and wide-angle functions. Therefore, the development of disposable cameras that are versatile, highly functional, easy to use, and low cost has become a major challenge.

However, if the photographing functions are diversified, the component parts of the camera will also be diversified accordingly, which may complicate the production process and lead to higher costs.

Particularly, in the winding mechanism section, the relationships between each part are complicated. Therefore, in the assembly process, various parts must be sequentially assembled to the body, which is the largest part, as a reference member, which is a major factor in increasing costs in both development and production.

In view of the above-mentioned points, it is an object of the present invention to provide a film-integrated camera that can simplify the assembly process of the winding mechanism and reduce costs through automatic assembly.

[Means to solve the problem]

To achieve the above object, the present invention provides a film integrated camera in which the film winding, shutter charge, and counter mechanisms are housed in a unit housing, and the film winding unit and body unit are assembled in separate processes. By integrating the two, it is possible to assemble the camera body, simplifying the entire process.
