Abstract

PURPOSE: To prevent a body cover and a holding means from being damaged with external force by attaching a reinforcing member to a camera main body. CONSTITUTION: The body cover 30 for constituting the appearance of a camera and preventing dust, etc., from entering into the internal part is provided outside the camera main body. An accessory shoe 6 is arranged in the upper part of the cover 30 and fixed on a reinforcing plate 1 inside the body cover 30 by a machine screw. The rear surface 1a of the reinforcing plate 1 is bent downward by 90 deg. and the side surface 1b is bent along the body cover 30. Further, the end face 1c of the reinforcing plate side surface 1b is bent in a horizontal direction. The reinforcing plate 1 is made of metal having conductivity and high rigidity and the rear surface 1a and a first frame 2 are fixed by the machine screw. Thus, even if great external force is exerted on an external stroboscope, the damage of the body cover and the stroboscope holding means can be prevented by the reinforcing member.

[0002]

2. Description of the Related Art FIG. 3 is a sectional view showing a strobe mounting mechanism (hereinafter referred to as an accessory shoe) of a conventional camera in the vicinity of a finder of the camera. On the outside of the camera body die casting 9, a camera top cover is shown. Reference numeral 5 is a finder unit, and 8 is a photometric block. However, these are not directly related to the present invention, and a description thereof will be omitted.

An accessory shoe 6 to which an external strobe can be attached is arranged outside the camera upper cover 30. The user attaches an external strobe to this accessory shoe and uses it under the condition that flash light emission is required. Some of the external strobes have a large amount of light emission, and when such a large strobe is attached and used, the accessory shoe 6 and the camera top cover 3 are affected by the external force applied to the strobe.
0 may be damaged. In order to prevent this damage even a little, in the conventional camera, the upper cover reinforcing plate 1 is provided inside the upper cover. The accessory shoe 6 is
It was attached to the reinforcing plate 1 with the upper cover 30 interposed therebetween.
In this way, the reinforcing plate 1 is reinforced so that the accessory shoe 6 and the upper cover 30 are less likely to be damaged. In addition, 34 indicates an eyepiece lens group. The eyepiece lens group 34 is integrally formed as the above-mentioned finder unit.

Here, in order to make it easier to compare the electronic still camera of the embodiment described later with the above-mentioned conventional technique, an electronic still camera in which the conventional technique is introduced (assumption) will be described with reference to FIGS. 2a and 2b. This electronic still camera was conceived in the process of reaching the present invention, and is not known as the prior art. In the following description, members having the same functions as those of the above-mentioned conventional technique are designated by the same reference numerals.

The first frame 2, the second frame 4, the third frame 7, and the body die cast 9 form a skeleton of the camera body, that is, a camera body body (hereinafter, also referred to as body body or body). An image pickup device (not shown) such as a CCD is arranged inside the body. Similarly, inside the body, a substrate 23 on which a circuit for performing processing such as compression / expansion of a captured image is formed is arranged. In addition, a recording medium required for an electronic still camera, a buffer memory, or
A circuit necessary for reproducing the recorded image, a CPU for controlling the circuits, and the like are arranged inside the body. However, since all of these can use known techniques, description thereof will be omitted here. In addition, the substrate 2 that performs various processes outside the body
Although 1 and 22 are arranged, their description is omitted.

A body cover 30 is provided on the outside of the body of the camera body to form the appearance of the camera and to prevent water, dust and the like from entering the inside. An accessory shoe 6 to which an accessory such as a strobe can be attached is arranged on the upper portion of the body cover 30, and the accessory shoe 6 is screwed to the reinforcing plate 1 inside the body cover 30.

The above-mentioned first frame 2 is fixed to the body die cast 9 with screws, and the lower part of the eyepiece cover 33 is fixed to the first frame 2 with two screws.
In addition, although the finder optical system 5, the photometric unit 8, and the liquid crystal display panel 31 are shown in FIGS. 2a and 2b, the description thereof is omitted because they are not directly related to the present invention.

[0008]

However, just by attaching the accessory shoe to the reinforcing plate 1 with the body cover 30 interposed therebetween as in the conventional case, a sufficient effect is obtained to cope with a large external force acting on the accessory shoe 6. I couldn't say. When a large external force is applied, the body cover 30 may be damaged.

Further, since the accessory shoe 6 is made of metal, when a high voltage such as static electricity is applied to this metal portion, there is a possibility that electronic parts inside the camera may be adversely affected. In recent cameras with many electronic components, the above-mentioned adverse effects of static electricity have become more serious. Further, in an electronic still camera that is expected to be manufactured in large numbers in the future, an image is picked up by an image pickup means such as a CCD, data is electrically processed, and recorded in a recording medium,
The adverse effects of static electricity as described above are likely to become more serious.
