And a reflection plate.

[0002]

2. Description of the Related Art In general, a strobe illuminates a subject with light at an irradiation angle corresponding to the angle of view of a photographic lens. When the strobe is mounted on a single-lens reflex camera, if the shooting angle of view changes due to replacement of the shooting lens, it is necessary to change the irradiation angle of the strobe accordingly. For example, when a wide-angle lens is used, the illumination light of the strobe cannot reach the periphery of the subject, and the periphery of the subject image corresponding to the periphery also becomes dark.

A strobe device provided with a light-transmitting diffusion plate as an irradiation angle conversion adapter for changing the irradiation angle of the strobe light is disclosed in Japanese Utility Model Publication No. 52-5643. In order to use the light-transmitting diffuser, the light-transmitting diffuser must be pulled out from the inside of the strobe body through a slot located under the light-emitting window of the strobe body. Is inserted into the main body of the strobe through the above-mentioned groove.

Also, when performing bounce photography using a strobe, even if strong strobe light is reflected on a ceiling or a white wall, a part of the reflected light often does not directly hit the eyes of a human subject. In order to solve the shortcoming, the photograph of the human subject's eyes is not lively,
The one equipped with a reflector on the strobe body
No. 05424 discloses this. According to this publication, a part of the illumination light of the strobe is reflected by the above-mentioned reflecting plate and guided to the eyes of a human subject.

Furthermore, there is an advantage that the reflection plate 5 is not damaged.

In addition, regarding the above-mentioned insertion, the reflection plate 5,
The state in which the irradiation angle conversion adapters 3 are sequentially inserted has been described. However, the order can be changed to be as follows. The portion of the reflector 5 shown in FIG. 5 which is located outside the flash body 2 is bent clockwise in the figure to maintain that state, and during the holding, the elastic force of the wire spring 7 or the click projection Insertion of the irradiation angle conversion adapter 3 is performed in the same manner as described above against the click force of 6a.

During the insertion, a part of the reflecting plate 5 is pushed upward by the engaging convex portion 3a of the adapter 3 and is elastically deformed. After insertion, the bent portion of the reflector 5 is restored. After the restoration, the strobe main body 2 is turned on its back, and the state at that time is shown in FIG. According to FIG. 7, the bounce flash can be performed using only the reflector 5. Following the insertion of the irradiation angle conversion adapter 3 described above, the reflection plate 5 in FIG. 7 can also be inserted as follows when being inserted into the strobe main body 2. The reflecting plate 5 in FIG. 7 is inserted into the storage chamber 2b of the main body 2 through the insertion opening 2a of the strobe main body 2,
At this time, the portion of the reflecting plate 5 that comes into contact with the engaging projection 3b is pushed up by the engagement projection 3b toward the notch 2c in FIG. 5, and is elastically deformed. When the reflecting plate 5 is completely inserted, the engaging projection 3a of FIG. 4 is engaged with the engaging recess 5b, and the reflecting plate 5 is restored, as described above. At this time, in a state where the reflection plate 5 is mounted on the irradiation angle conversion adapter 3, the height of the inner space of the storage chamber 2 b is adjusted by the above-described irradiation angle conversion adapter in order to accommodate both the irradiation angles 3 and 5. It is not necessary to expand the thickness beyond the total thickness of the reflectors 3 and the reflector 5, and the height can be suppressed.

One of the irradiation angle conversion adapter 3 and the reflection plate 5 is inserted into the strobe main body 2, and strobe photography can be performed using only the other left outside the strobe main body 2. Therefore, it goes without saying that the range of types of flash photography can be expanded.

Further, the holding plate 6 in FIG. 3 is provided in order to rotatably hold the irradiation angle conversion adapter 3, but as another example, if it satisfies the following structural requirements, You can use it. The constituent requirements are “the illumination angle conversion adapter 3 is connected to the illumination angle conversion adapter 3, and the illumination angle conversion adapter 3 is rotatably held. The strobe body 2 is disposed so as to be able to freely follow the strobe body 2 ". In addition to the holding plate 6 shown in FIG. Of course, any suitable holding member can be used.

The wire spring 7 shown in FIG. 3 is formed so as to surround the periphery of the holding plate 6. However, as another elastic member, for example, a wire spring having a short overall length can be used. At this time, one end of the above-mentioned spring is connected to the insertion portion 3c of the irradiation angle conversion adapter 3 in FIG. 3 to maintain the connection, and the holding plate 6 on which the above-mentioned click projection 6a is located.
The other end of the above-described wire-working spring is connected to a portion near the adapter 3 on the side surface of the above-mentioned wire-working spring, and around the X-axis in FIG. The irradiation angle conversion adapter 3 may be rotated by the elastic force (tensile force) of FIG.

Further, the above-mentioned irradiation angle conversion adapter 3
Described that a large number of pyramid-shaped portions were formed on the surface of a transparent material in order to diffuse light, but as the present invention, a Fresnel lens provided with a saw-tooth-shaped portion was used. A thin plate-shaped convex lens may be used as the irradiation angle conversion adapter 3 described above. At this time, if the illumination angle of the strobe light is adjusted to a narrow angle by the optical characteristics of the above-described convex lens in accordance with the telephoto lens attached to the main body of the single-lens reflex camera, the narrow photographing angle of view of the above-described telephoto lens can be obtained. It is well known that the strobe light can be stopped down to increase the strobe guide number.

[0033]

As described above, according to the present invention, when the irradiation angle conversion adapter or the reflection plate is not used, it can be housed in the housing room through the slot of the strobe main body. There is no need to worry about being lost or forgotten.In addition, simply pulling out the above-mentioned drawer knob can pull out the illumination angle conversion adapter and reflector out of the strobe body, saving the trouble of drawing out. In that case, both the irradiation angle conversion adapter and the reflector can be used at the same time.

In addition, the reflection plate can be inserted into the insertion / removal opening of the strobe main body with the reflection plate mounted on the irradiation angle conversion adapter, and the storage chamber of the strobe main body can be irradiated through the insertion / removal opening. Since both can be accommodated with the reflection plate mounted on the angle conversion adapter, it is not necessary to further extend the vertical length of the insertion / removal opening or the height of the inner space of the accommodation room. Thus, the strobe body can be kept small.
