Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a cover that can selectively cover both a flash device mounting portion (hereinafter referred to as a hot flash) and an eyepiece frame.

"Prior art and its problems" Conventionally, in a camera with a hot show,
No active measures have been taken to prevent the flash electric contacts (hereinafter referred to as "X contacts") of hot shots from being contaminated with dirt, oil, etc., or from being scratched.
This has caused problems such as the flash device malfunctioning or not emitting light.

On the other hand, automatic exposure control cameras are configured to use a light-receiving element to detect the light that has passed through the photographic lens to control exposure. If you take a picture without it, the light beam entering from the eyepiece frame will be reflected on the glass or resin material of the eyepiece optical system and will enter the light receiving element for automatic exposure control, and as a result, the automatic exposure control circuit will not be able to detect the original subject. It reads not only the side light rays, but also the light rays incident from the eyepiece frame, and judges these as if they were from the subject side. Then, exposure control is performed under conditions for photographing a subject that is brighter than the actual subject, and the photograph actually obtained will be underexposed.

To solve the above two problems, the camera user must carry a cover to protect the X contact and to shield the eyepiece frame from light.

"Purpose of the Invention" The present invention has been made to solve these conventional problems, and aims to provide a cover that can selectively cover the X-contact and the eyepiece frame.

"Summary of the invention" The common cover of the invention includes a fixing member that has an arm part that can fit into a flash device mounting groove formed in the hot shoe and a flange part that can fit into a frame groove formed in the eyepiece frame. A pair of fixing members are provided, and these fixing members are connected by a foldable cover member. When the cover member is extended, the pair of flanges fit into the frame grooves and the cover member covers the eyepiece frame, and when the cover member is folded, the pair of arms fit into the flash device mounting grooves to close the cover. The member covers the X contact of the hot shoe.

"Example of idea" The present invention will be explained below with reference to illustrated embodiments.

1 and 2 show an embodiment of the present invention. In these figures, the shared cover is bilaterally symmetrical and consists of a pair of fixing members 10, 20 and a cover member 30 connecting these fixing members. The fixing members 10 and 20 have arm portions 11 and 2, respectively.
1 and collar portions 12 and 22. Each arm 11, 21
are mutually directed outward, and the respective flanges 12, 22 are mutually directed inward. The cover member 30 includes a middle plate 31 located at the center, thin plates 32 and 33 located on both sides of the middle plate 31, and an outer plate located outside these thin plates and connected to the arms 11 and 21. 34 and 35. The middle plate 31 and the thin plates 32, 33 are connected by thin parts 36, 37 that curve upward in FIG. 1, and the thin plates 32, 33 and the outer plates 34, 35 are connected by thin parts 38, 39.
Each of the thin parts 36, 37, 38, 39 can be bent so that the protruding side faces outward (see FIG. 2). Therefore, the cover member 30
In this case, the thin plates 32 and 33 are the middle plate 31 and the outer plates 34 and 35.
It can be folded so that it is sandwiched between the two. In the folded state, the thin parts 38 and 39 are alternately close to each other, and the thin parts 36 and 37 are close to the flanges 12 and 22 and the outer plate 3.
4 and 35, respectively. Note that a hook portion 43 is formed on the middle plate 31 and extends in a direction perpendicular thereto. Also, one end of the grooves 41, 42 is provided with a closing portion 41a, 42a for closing the groove.

The common cover of the present invention having the above configuration has the following features when the cover member 30 is extended (FIG. 1):
It can be attached to the eyepiece frame 50 of the camera shown in FIG. That is, the flanges 12 and 22 can fit into frame grooves 51 and 52 formed on both outer sides of the eyepiece frame 50, respectively, and the grooves 41 and 42 fit into the protrusions 53 formed on the sides of the frame grooves 51 and 52. , 54, respectively. Therefore, the thickness A of the flanges 12, 22 substantially matches the width a of the frame grooves 51, 52, and the flanges 12, 22 when the cover member 30 is stretched out,
The distance B between the two frame grooves 51 and 52 substantially corresponds to the distance b between the bottoms of the two frame grooves 51 and 52.

FIG. 4 shows the state before the cover is attached to the eyepiece frame 50. In this state, the cover is placed directly above the eyepiece frame 50 with the hook portion 43 facing upward. The flange portions 12 and 22 are connected to the frame groove 51 of the eyepiece frame 50,
52 and hook part 43 or closing part 4
The cover is lowered until 1a and 42a are engaged with the upper surface 53 of the frame groove 50. As a result, the cover member 3
0 completely covers the eyepiece frame 50 as shown in FIG.

On the other hand, the common cover of the present invention can be attached to the hot shoe 60 of the cover shown in FIG. 6 when the cover member 30 is folded (FIG. 2).
The hot shoot 60 has flash device mounting grooves 61 and 62.
It has support plates 63 and 64 inside, and springs 65 and 66 that always bias these support plates upward, and also has an X contact 67 in the center. The arms 11 and 21 of the common cover of the present invention are inserted between the upper surfaces of the mounting grooves 61 and 62 and the support plates 63 and 64 by compressing the springs 65 and 66. The thickness C of the arm portions 11 and 21 is
Springs 65, 66 are configured to press support plates 63, 64 against arms 11, 21 with an appropriate amount of force. Further, the distance D between the outer ends of the arm portions 11 and 22 in the folded state of the cover member 30 substantially corresponds to the distance d between the bottoms of the two mounting grooves 61 and 62.

FIG. 7 shows the cover attached to the hot shoe 60. As can be seen from this figure, the x contact 67 is covered and protected by the cover member 30.
At this time, the arms 11 and 21 are pressed by springs 65 and 66 to prevent the cover from coming off from the hot shoe 60.

"Effects of the Invention" As described above, the common cover of the present invention can be attached to the eyepiece frame of the cover with the cover member stretched out. Therefore, in an automatic exposure control camera, this common cover can be attached to the eyepiece frame during self-timer photography to block incident light from the eyepiece and prevent underexposure. Further, the common cover of the present invention can be attached to a camera hot shoe with the cover member folded. Therefore, the X contact is protected, and dirt and scratches on the X contact, which would cause malfunction of the flash device, are prevented. As described above, according to the present invention, it is possible to shield the eyepiece frame from light and protect the X contact with a single cover, thereby eliminating the conventional complication of having to carry two types of covers.
