[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic camera.
[0002]
[Prior art]
Conventionally, an electronic camera has various parts such as a photographing lens, an image pickup element, a display element, a backlight device, and a circuit board. However, assembling these parts separately in the camera body requires Since it is cumbersome and cumbersome, it is considered to assemble various parts into units for each function. For example, among various components, the photographing lens and the imaging device are used as a photographing unit, the display device and the backlight device are used as a display unit, and a circuit board on which various electronic components such as LSI are mounted is integrated as a substrate unit. These component units are assembled in the camera body.
[0003]
In this case, as a structure for assembling various component units in the camera body, for example, a structure in which each component unit is mounted in the camera body by screwing, or mounting protrusions such as mounting bosses and mounting pins are integrated in the camera body. There is a structure in which each component unit is attached to the camera body by these attachment projections.
[0004]
[Problems to be solved by the invention]
However, in the mounting structure in which the component unit is screwed as in the former, since it is necessary to screw in each component unit, the screwing operation is cumbersome and the workability is not good, and the screw hole into which the screw is screwed is formed. Since the camera body must be provided with the bosses and ribs that it has, the shape of the camera body is complicated, and the wall thickness of the camera body is required to secure the installation space for these bosses and ribs and to ensure the strength of the camera body. Therefore, there is a problem that the entire camera cannot be reduced in size and thickness.
[0005]
In addition, in the latter mounting structure in which the component unit is mounted with mounting protrusions such as mounting bosses and mounting pins, the mounting protrusions must be formed integrally with the camera body according to the shape suitable for each component unit. Therefore, the shape of these mounting projections becomes complicated, and the production of the camera body is complicated accordingly.In addition to these mounting projections, as in the former case, the installation space can be secured, In order to ensure the strength of the camera body, it is necessary to increase the wall thickness of the camera body. Therefore, there is a problem that the entire camera cannot be reduced in size and thickness. In particular, it is conceivable to form the camera body with a metal plate such as stainless steel in order to ensure the strength. However, it is technically difficult to integrally form the mounting protrusion on the metal plate.
[0006]
An object of the present invention is to make it possible to easily assemble a component unit in a camera body without using a screw or a mounting projection.
[0007]
