Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof camera case. More specifically, the present invention is
A new waterproof camera that allows divers to easily check the subject and focus the camera, which is useful for underwater photography by storing ordinary cameras such as single-lens reflex cameras in waterproof camera cases and bringing them underwater. It is about the case.

[0002]

2. Description of the Related Art In water, due to the flow and resistance of water, the positional relationship between the diver, camera, and subject is constantly changing and unstable, and in water where the amount of light is insufficient, the function of the eyes themselves deteriorates. It becomes difficult to capture the image in the viewfinder quickly. This is automatic in the waterproof camera case.
The same applies to the case where a high-performance single-lens reflex camera with a focus function is stored, and even if it is brought under the surface of the water, it will still be darker than on land, and due to insufficient light intensity and small fluctuations of the light image in the water, the camera focus adjustment It is difficult. In addition, there is an example in which a waterproof light is attached to the underwater strobe to make it easier to focus when the amount of light in the water is insufficient.However, the weight on the strobe side, which is far from the center of gravity of the camera, becomes large, which makes the overall handling easier. It gets worse, it can not be operated integrally with the shutter operation of the camera, and the strobe irradiation is basically from the side of the subject, but the target setting light is applied from the front, so the strobe arm is repeatedly used. There are many problems such as the troublesome work of bending.

Furthermore, even if a land-based camera equipped with a target light that also serves as a red-eye prevention is housed in a transparent waterproof case and used in water, only about one-third of the light in land is emitted in water. Since it does not pass through, it is useless due to lack of light. For this reason, conventionally, only experienced divers have incorporated a well-known high-performance camera into a specific waterproof camera case,
Underwater photography was so difficult that I could finally take one of the pictures I intended after getting used to the equipment through trial and error underwater photography.

In fact, most failed photographs are caused by mistakes in targeting and focusing, such as that the fish of the subject is in the composition only in the tail or out of focus and only the background rocks can be recognized. Is.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention
As mentioned above, in the past, divers stored ordinary cameras such as single-lens reflex cameras in a waterproof camera case and brought it under dark water where it was difficult for light to pass through, and when shooting underwater, mis-targeting and focusing Since many cases of failure due to mistakes are made, it is an object of the present invention to provide an improved waterproof camera case in which targeting and focusing are reliable and easy.

[0006]

In order to solve the above problems, the present invention illuminates the photographing direction of a built-in camera on the front part of the case body to assist in confirming the subject and focusing the camera. A waterproof camera case equipped with a target light. With this waterproof camera case, immediately before underwater photography, it is possible to illuminate a bright target light with strong directivity, to confirm the illuminated subject, and to confirm the photographing direction of the built-in camera.

Further, it is possible to ensure the focusing of the camera when the target light is emitted.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A specific technical configuration of means for solving the problems of the present invention will be described below with reference to the drawings. <A> First, regarding normal cameras other than the disposable type, as shown in FIG. 1, when the shutter button (11) is pushed in, the photometric system of the camera first operates. After the start of shooting, preparation for shooting such as focusing is performed (first step), and when the button is pushed further, the shutter is opened, strobe light is emitted, and shooting is performed (second step). ing.

Therefore, in the waterproof camera case of the present invention, as illustrated in FIG. 2, the outside of the case body (21) in which a camera such as a single-lens reflex camera is built in so as to completely prevent entry of water under water pressure. An operation key (22) for operating the built-in camera from the outside is provided in the part, and the external operation key and the operation portion shutter button (11) shown in FIG. 1 of the built-in camera are electromagnetically or mechanically provided. By providing a link system that is tightly connected, the key operation from outside the case body (21) of the waterproof camera case pushes the operation key (22) like the shutter button (11) operation of the built-in camera. First, the photometric system of the camera started to operate, preparation for shooting such as focusing was done (first step), and when it was pushed in further, the shutter was released and the flash was released. Lamp emission, photography is to ensure the two-stage configuration in which (second step) carried out.

Then, by pushing the external operation key (22) from the outside of the case body (21), the shutter button (11) operation of the built-in camera is synchronized and the photometric system of the built-in camera starts operating. Then, in the first stage when preparation for shooting such as focusing is performed, that is, immediately before underwater shooting, the switch of the target light (23) provided on the case body (21) is turned on, and directivity is strong. The light from the bright target light (23) is emitted.

The diver can confirm the shooting direction of the built-in camera by visually recognizing the illuminated subject. At the same time, focusing of the camera can be ensured. If the built-in camera has an auto-focus function, even in dark water where it is difficult for the light to reach, a sufficient amount of light is secured for automatic focusing when irradiating the target light (23), and even small fluctuations of the light image in water are possible. Since it is temporarily frozen, automatic focus adjustment is reliably performed.

If the diver further pushes the external operation key (22) of the waterproof camera case, the shutter button operation of the built-in camera is synchronized and the second stage is entered.
The shutter is released, the flash fires, and the picture is taken, so you can take a good underwater picture with no targeting or focus mistakes. <B> Next, a more specific link system that connects the external operation keys (22) on the outer side of the case body (21) and the shutter button (11) of the built-in camera electromagnetically or mechanically The configuration will be described.

First, the shutter button (1
1) The operation mechanism has a deep pushing stroke, and the first stage stroke with a light pushing force starts the operation of the photometric system, and the camera is ready for shooting. With a second pushing stroke with a slightly stronger pushing force, the shutter is released. Open,
In the case of a weak / strong two-stage stroke configuration in which stroboscopic light emission and shooting are performed, the link system may be simple, and the external operation keys (22) shown in FIG. 2 and the built-in camera shown in FIG. It is sufficient that the shutter button (11) and the shutter button (11) are always in physical contact with each other.

The external operation key (22) in contact with the shutter button (11) of the built-in camera is also linked to the lighting switch of the target light (23), so that the shutter button (11) of the first stage When the stroke is a light half-press, that is, when the camera's autofocus mechanism is operating, the target light (23) is illuminated and the subject is illuminated brightly. Can be definitely decided.

When the pushing stroke of the second stage is further performed with a strong pushing force, the target light (2
The switch in 3) is turned off, the shutter is released, the flash fires, and the picture is taken, allowing you to take a beautiful underwater picture. External operation key (22) and target light (2
The interlocking with the lighting of 3) is such that a metal piece is embedded in a part of the pushing member of the external operation key (22) and a solenoid-shaped electromagnetic sensitive section is provided on the tubular member around it to make it into a switch or a small size. It is realized by interposing a tact switch.

Further, the shutter button (1
1) When the operating mechanism does not have a deep pushing stroke, the link system is a mechanical stroke expanding mechanism applying a lever, that is, a case body of a waterproof camera case, as illustrated in FIG. (21) A link mechanism that has a fulcrum (31) in the housing and is integrated with a long arm portion (32) extending to the external operation key (22) and a short arm portion (33) in contact with the shutter button (11). It can be accommodated by interposing between the external operation key (22) and the shutter button (11) of the built-in camera (12).

If the shutter button (11) operating mechanism of the built-in camera (12) does not have a weak / strong two-stage stroke structure, or if the strength is weak and it is difficult to see the strength by a mechanical operation, then FIG. As illustrated in, the coil spring (41) that restores the pressing of the external operation key (22).
The pressing elastic force of the two is set to weak and strong in two steps, and the pressing operation mechanism of the entire link system between the external operation key (22) and the shutter button (11) of the built-in camera has a weak and strong two-step stroke configuration. May be.

The structure illustrated in FIG. 4 employs a magnetically sensitive two-stage reed switch mechanism, which has a magnetically sensitive reed switch (4) in the stroke direction.
This is a mechanism in which two magnets (2) are arranged side by side and a moving space for the magnet (43) fixed to the end of the stroke button that is connected to the operation key (22) is provided on the side of the magnet. The sensitive reed switch (42) is sensitive and adjusts the pressing of the shutter button (11) via the electronic circuit (44). Target light (23)
Is also turned on / off by this response.

In a three-layer leaf spring laminated switch (51) as shown in FIG. 5, only the upper leaf spring (51a) is pushed down in the first step (FIG. 5 (b)), and the upper leaf spring (51a). As the second step (Fig. 5 (c)) of contact with the lower leaf spring (51c) by pushing down the intermediate leaf spring (51b), each contact state is detected and the target light (23) is turned on by the electronic relay circuit. , The mechanism to turn off the external operation key (2
It is possible to realize a weak / strong two-stage stroke structure for the pressing operation mechanism of the entire link system between 2) and the shutter button (11) of the built-in camera.

With such a hardware configuration, the shutter button interlocking operation key (22) of the waterproof camera case
When the first half of the stroke is a light half-stroke, that is, when the photometry system such as the autofocus mechanism of the camera is operating, the target light (23) is simultaneously illuminated to brightly illuminate the subject, which causes insufficient water. Above all,
The focus is in focus and the composition can be determined with certainty. When the push stroke of the second stage with a strong push force is reached, the switch of the target light (23) is turned off, the shutter is opened, the flash is fired, and the shooting is performed.
You can take beautiful underwater photos. Since the underwater photography by these series of operations can be performed without being aware of a special operation, the diver can concentrate on the examination of the content of the photography.

At the time of illuminating the subject with a lightly half-pressed stroke in the first stage, if you are not satisfied with the composition and want to stop shooting, you can change the shooting freely by removing your fingertips and returning the stroke. You can Also, after the first stage switch is turned on, if the fingertip is released and the stroke is returned, the target light (2
It is preferable to incorporate a delay circuit so that (3) continues to be lit so that the nerve can be more focused on the composition determination and focus adjustment of the subject.

In the case of a camera in which a signal for informing the state of pressing the shutter button corresponding to the stroke of the first stage and the stroke of the second stage is transmitted from the electric contact of the hot shoe of the strobe mounting portion toward the intelligent strobe, It is also possible to receive this and turn on and off the target light. The lighting switch of the target light (23) is basically operated by the shutter button interlocking external operation key (22) on the outer portion of the case body (21) as described above, but only the lighting of the target light is separately performed. It is desirable to provide a key for operating. If this target light dedicated key is used, it can be used for communication with other divers and transmission of emergency signals.

The target light (23) is, for example, as shown in FIG. 4, a hemispherical reflecting mirror (231) incorporated in the front recess of the waterproof camera case and a transparent plate (232) in front of it. A light bulb (233) is provided in the space surrounded by. As the light bulb (233), a halogen lamp with high power consumption but high illuminance,
For high illuminance, low power consumption krypton lamps, xenon lamps, etc. are suitable.

<C> Further, the finder system of the waterproof camera case of the present invention will be described. In the waterproof camera case of this invention, since the case body (21) is equipped with the target light (23), the diver is
The target light (23) just before I tried to shoot
You can check the shooting direction of the built-in camera by illuminating.

In this case, as illustrated in FIG. 6, the pickup finder section (24) in the latter half of the case body (21) of the waterproof camera case has an optical axis which is the same as that of the finder (13) of the built-in camera (12). The pickup finder (2
By looking through the finder (13) of the camera through 4), it is possible to confirm the subject and visually recognize the photographic information displayed in the finder from the camera.

Even if it is difficult to look through the viewfinder (13) of the camera due to the situation of the shooting site, if the target light (23) in front of the camera held at an oblique position is illuminated, the subject can be seen. You can check. The optical axis of the pickup finder section (24) of the camera case and the finder (13) of the built-in camera should match the built-in camera (12) with its tripod fixing hole (1).
It is realized by fixing it to the case body while accurately positioning it using 4) or the like.

Further, the pickup finder section (24) of the camera case has a finder magnification of the built-in camera (12) in consideration of the situation of a diver who wears underwater glasses and cannot keep his eyes sufficiently close to the finder of the camera. It is desirable to incorporate a lens system that extends the eyepoint while suppressing the drop. Further, in this waterproof camera case, the pickup finder section (24) can be provided with a diopter correction function. The pickup finder section (24) with the diopter correction function is composed of an eyepiece convex lens (242) and a fixed objective concave lens (243) which can be moved forward and backward by the rotation of a screw (241), as illustrated in FIG. 7, for example. It can be configured and realizes a diopter correction function that allows accurate diopter correction at underwater shooting sites by adjusting the distance between both lenses. More specifically, as shown in FIG. 7, in the viewfinder section (13) of the camera (12) body, the fixed objective concave lens (243) is opposed to the viewfinder lens (131) by the lens retainer (244).
The camera case body (21) has a cylindrical hole (2) for operation.
The eyepiece lens (24
O-ring (247) that supports 2) and is made of silicone rubber, etc.
Mounting via. The tubular body (246) is prevented from coming off by the retaining ring (248), and can be moved back and forth by the screw (241) as described above.

In this example, a fixed objective concave lens (243) is attached to the finder section (13) of the camera body. This one has the function of extending the eyepoint while suppressing the reduction of the viewfinder magnification of the built-in camera (12), and the eyepiece convex lens (242) assembled in the latter half of the waterproof camera case maintains the waterproof performance. It can be moved back and forth by rotating the screw, and has a diopter correction function in cooperation with the fixed objective concave lens (243).

The conventional pickup lens system for a waterproof camera case is either fixed to the finder of the built-in camera body or installed inside the waterproof transparent peep window of the waterproof camera case. None of them made it possible to perform accurate diopter correction. For this reason, in water, due to insufficient light intensity, low water temperature, etc., the diver's eyes themselves physiologically deteriorate, making it difficult to capture the image in the viewfinder. On the other hand, the diopter correction in water by adjusting the distance between both lenses as described above in the present invention is extremely important and effective for realizing accurate underwater photography.

<D> Next, the structure of the waterproof camera case of the present invention will be described. The waterproof camera case is basically
It is composed of an internal space for housing the camera and a wall surface around which mechanical members and functional parts are incorporated. The outer shell-shaped case body can be opened or divided for inserting and removing the camera. The form of division may be appropriately divided into two parts, a storage main body and a lid, or a hemispherical two-part body. In either case, it is essential that the joint portion of the divided body has a waterproof seal structure.

Here, a detailed structure of the waterproof camera case will be described with reference to FIG. 8 while exemplifying a case where the waterproof camera case is typically composed of a substantially hemispherical two-divided body.

For example, as shown in FIG. 9, the extending objective concave lens (243) portion has a concave lens front half portion and a lens pressing portion (24) which are exposed and protrude so as to be fitted into a finder frame (249).
Objective concave lens (243) consisting of a concave lens latter half part which is covered and fixed to the frame of 4), an objective concave lens having a frame covering the concave lens latter half part and a finder frame (249) mounting spring locking part. Hold down (2
44) and a spring (250) for attaching the camera body (12) to the finder frame, and the like. The concave lens (243) of the objective concave lens section is
The outer shape of the finder frame (249) is the same as that of the finder frame (249) so that the finder frame (2) is sufficiently close to the camera body finder lens (131).
By being fixed within 49), it is possible to suppress the reduction of the viewfinder magnification and to extend the eyepoint greatly.

On the other hand, it is attached to the rear half of the waterproof camera case body (21) and can be moved back and forth by rotating the screw while maintaining the waterproof performance. By adjusting the distance from the objective concave lens (243), it is possible to see underwater. Convex lens (2
As already mentioned above, the portion 42) has a circular dial (245) which has a large diameter and can be easily rotated in water, and an eyepiece convex lens (24) which is waterproofed and fixed to the inside of the circular dial.
2), an eyepiece convex lens barrel that extends from the eyepiece convex lens fixing part in a cylindrical shape with an inner diameter approximately the same as the lens diameter, and has an outer surface with a thread groove that meshes with the inner thread groove of the eyepiece convex lens assembly cylindrical hole in the latter half of the camera case. (246), a waterproof O-ring (247) for waterproof sealing between the outer surface of the eyepiece convex lens barrel (246) and the inner surface of the camera case tubular hole, that is, an O-ring sealing rubber and an eyepiece convex lens barrel (246). It can be configured by a captive retaining ring (248) attached to the front end of the eyepiece convex lens barrel (246) in order to prevent it from falling off from the camera case tubular hole.

As described above, the waterproof camera case of the present invention is equipped with various electronic equipments and optical systems for performing underwater photography easily and surely, and even general divers need not be a skilled diver. Enjoy beautiful underwater photography. Moreover, the operation system such as the link system between the external operation key and the built-in camera and the interlocking part of the target light lighting switch,
As described above, the human interface is designed so as not to feel uncomfortable with the operation of a normal camera on land, so that the user can concentrate his or her attention on the content of the image and can easily take a good image.

Further, in the present invention, an underwater strobe may be attached. In this case, as shown in FIG. 10, the electric signal control unit part (16) for the illumination lamp such as the strobe installed inside the case body is connected to the underwater strobe (1) to be externally connected.

Moreover, since the reduction of the viewfinder magnification is suppressed and the eye point is extended, the image in the viewfinder is captured in a sufficient size to check the subject, and the shooting information displayed in the corners of the viewfinder is also reliable. Visible. Further, the diopter correction of the pickup lens system and the camera focusing can be performed with high accuracy while observing the image inside the bright and large finder.

[0039]

As described above, the present invention allows divers to bring a normal camera such as a single-lens reflex camera into a waterproof camera case and bring it under the surface of the water to cause a targeting error or a focusing error when shooting underwater. Since there are so many cases where the camera fails to meet the requirements, we will realize a waterproof camera case that can achieve targeting and focusing safely and reliably and does not easily fail.

That is, the waterproof camera case is equipped with a target light for illuminating the shooting direction of the built-in camera to confirm the subject and to assist the focus of the camera at the front part of the waterproof camera case. , The directivity is strong and a bright target light is emitted to visually recognize the illuminated subject, and the shooting direction of the built-in camera can be confirmed.
