BACKGROUND OF THE INVENTION
The present invention relates to a camera, and more particularly, to a method for connecting an outer cover that covers a main body base having a photographing mechanism.
[0002]
[Prior art]
Generally, a camera body is configured by covering a main body base in which various functional parts necessary for photographing are incorporated with an outer cover serving as an exterior. Functional parts incorporated in the main body base include a photographing lens, operation buttons, a liquid crystal panel, and the like, and these are exposed to the outside through a hole formed in the outer cover. Further, in the case of an instant camera, a claw member that scrapes out a self-development processing type film unit, a developing roller that unfolds the scraped film unit, and the like are incorporated in the main body base.
[0003]
On the other hand, in an inexpensive compact camera, instant camera, or the like, most of the configuration is generally occupied by resin molded parts molded by an injection molding method. The injection molding method is a method in which a resin liquid is injected at a high pressure into a mold having a space that follows the outer shape of the object to be molded, and this is cooled and solidified. Can be reduced. Furthermore, in order to reduce the manufacturing cost, the parts are assembled by claw locking or the like without using screwing as a method of joining the parts.
