DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film unit with a lens, a sheet-like mirror, and a strobe device for a film unit with a lens.

[0002]

2. Description of the Related Art In a film unit with a lens, a convex mirror is provided on a front surface of a camera body in order to project an image of an object to be photographed so that the image can be viewed from the object side. The convex mirror is formed by plating the surface of a resin base material, and is separate from the camera body of the film unit with the lens. Therefore,
In use, a subject image is projected by attaching a convex mirror to the camera body.

On the other hand, in a flash unit of a film unit with a lens, a back surface of a light source is surrounded by a reflecting mirror. As this reflector, high-brightness aluminum is conventionally used in order to increase the irradiation light from the light source.

[0004]

In the case where the convex mirror is provided separately from the camera body, it is necessary to attach the convex mirror to the camera body each time it is used, which is troublesome and impractical. On the other hand, when the convex mirror is integrated with the camera body by plating the surface of the camera body, it is expensive and is not preferable. For this reason, it is conceivable to attach a sheet-like mirror to the front of the camera body. In this case, the lens-fitted film unit is generally small, and the radius of curvature of the convex surface needs to be about 100 mm in order to project the photographer himself. However, when a sheet-like mirror is stuck on a convex surface having such dimensions, wrinkles are generated on the sheet-like mirror, which not only impairs the function of the mirror but also deteriorates the outer surface. I have.

[0005] On the other hand, high-brightness aluminum used as a reflector of a strobe device is easily damaged, so it is necessary to cover and protect it with a protective sheet. After this attachment, the protection sheet is peeled off. For this reason, handling is difficult and installation is troublesome. In addition, high-brightness aluminum is expensive, and is incompatible with inexpensive film units with lenses.

The present invention has been made in consideration of such a conventional problem. Even if a sheet-like mirror is attached to a camera body to project a subject image, wrinkles do not occur. It is an object of the present invention to provide a film unit with a lens which can function well as a mirror and whose outer surface does not deteriorate and a sheet-like mirror suitable for the film unit.

A diffusion panel 30 is provided on the front surface of the reflection plate 27. The diffusion panel 30 includes a lens body 31 that covers the front surface of the reflection plate 27, and a support plate 32 that supports the periphery of the lens body 31. The diffusion panel 30 is mounted so as to cover the front surface of the reflection plate 27 by inserting pins 32 a formed on the support plate 31 into pin holes of the bracket 28 in the cover lid 7. In addition, by pulling out the pin 32 a from the pin hole of the bracket 28, the pin 32 a can be removed from the front surface of the reflection plate 27. Therefore, the entire diffusion panel 30 is detachable from the strobe device 6, and replacement is easy.

The reflecting plate 27 is formed in an arc-shaped cross section, and
5 is formed, and a sheet-like mirror 34 attached to the inner surface of the hood 33 is formed. FIG. 11A shows a reflection plate 27 corresponding to FIGS. 9 and 10, in which a hood 33 is formed of phosphor bronze, a plated iron material, or ordinary aluminum or an alloy thereof. By attaching the sheet-like mirror 34 to the inner surface of the hood 33, the sheet-like mirror 34 reflects the strobe light from the light source 25 to enable strobe photography.
Therefore, the entire reflection plate 27 can be formed of an inexpensive material without using high-brightness aluminum, and troublesome handling and complicated mounting like high-brightness aluminum are not required.

FIGS. 11B and 11C show another embodiment of the reflection plate 27. FIG. In FIG. 11B, the hood 33 is formed of a resin molded product. The hood 33 made of a resin molded product has a thick block shape, and has a reflective hole 35 having an arc-shaped cross section formed therein. A sheet-like mirror 34 is attached along the reflective hole 35. By using the hood 33 as a resin molded product, the reflection plate 27 can be made lightweight and inexpensive.

In FIG. 11C, a concave portion 36 having an arc-shaped cross section is directly formed on the front surface of the camera body 1. Further, a base material 37 made of a paper material is formed into an arc shape, and a sheet-like mirror 34 is attached to an inner surface of the base material 37. Then, by fitting the base material 37 with the sheet-shaped mirror 34 attached thereto into the concave portion 36 and bonding the same, the reflection plate 27 integrated with the camera body 1 can be formed. This FIG.
The structure (c) is composed of a paper material and a thin sheet-shaped mirror, so that there is an advantage that when the film is taken out from the camera body 1 and the camera body 1 is recycled, the sheet-shaped mirror can be removed and incinerated.

In each of the reflectors 27 shown in FIGS. 11B and 11C, similarly to FIG. 11A, there is no need to use expensive, high-brightness aluminum which is cumbersome to handle and mount.

Next, the operation of the diffusion panel 30 will be described. As shown in FIGS. 9 and 10, the entirety of the diffusion panel 30 is detachable from the strobe device 6 by the pins 32a. Therefore, instead of a panel having a normal convex lens, a diffusion panel 30 having a different lens body 31 such as a concave lens can be attached to the strobe device 6. Therefore, it is possible to arbitrarily perform strobe lighting according to the focal length of the photographing lens 8. In this case, panoramic photography can be performed without changing other members of the strobe device such as the light source 8 and the reflection plate 27, so that other members of the strobe device can be used for general purposes.

FIG. 12 to FIG. 14 show the operation when the diffusion panel 30 having a different lens body is replaced.
(A) is a side view and (b) is a plan view. In this embodiment, by replacing the diffusion panel 30,
The lens body 31 can be a concave lens 38 as shown in FIG. 12, or a Fresnel lens 39 having a concave lens action as shown in FIG.

FIG. 14 shows a case where the diffusion panel 30 is a convex lens 40 used in a normal strobe device. In the convex lens 40, as shown in FIG. 14, the strobe lighting is performed for the angle of view of the photographing lens 8 having a narrow diffusion width of the strobe light and a focal length of about 30 mm. In contrast, concave lens 3
8 and the Fresnel lens 39 having a concave lens action, as shown in FIGS. 12 and 13, the diffusion width of the strobe light is widened, and the angle of view of the super-wide-angle photographing lens 8 having a focal length of 15 to 25 mm is reduced. Can be covered. Therefore, even with a lens-equipped film unit having an ultra-wide-angle photographing lens 8, the other members of the strobe device 6 can be obtained simply by mounting the diffusion panel 30 having the concave lens 38 or the Fresnel lens 39 having the concave lens function. Can be used for flash photography.

In the present invention, various modifications are possible without being limited to the above-described embodiment.
The structure for making the diffusion panel 30 detachable can be achieved by hooks, clips, hook-and-loop fasteners, or other means other than pins. Further, the reflecting plate 2 on which the sheet-like mirror 34 is adhered together with the concave lens 38 and the Fresnel lens 39 having the concave lens function shown in FIGS.
7 can be used, so that stroboscopic illumination corresponding to an ultra-wide angle of view can be performed even though it is inexpensive and easy to assemble.
