[Industrial applications]

 The present invention relates to a strobe device, and more specifically, it includes an irradiation angle conversion adapter for changing the irradiation angle of a strobe, and a reflector for guiding a part of strobe irradiation light toward a subject. The present invention relates to a strobe device.

[0002]

[Prior art]

 Strobes generally illuminate a subject with an illumination angle that corresponds to the angle of view of the taking lens. When the strobe is attached to 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 strobe irradiation angle accordingly. For example, if a wide-angle lens is used, the light emitted from the strobe cannot reach the periphery of the subject, and the periphery of the subject image corresponding to the periphery will also be dark.

Therefore, a strobe device having a translucent diffuser plate as an irradiation angle conversion adapter for changing the irradiation angle of a strobe is disclosed in Japanese Utility Model Publication No. 52-5643. To use the translucent diffuser plate, pull out the translucent diffuser plate from the inside of the strobe body through the slot located at the bottom of the flash window of the strobe body. A strobe device is described in which the diffuser plate is inserted into the strobe body through the above-mentioned slot.

In addition, when bounce photography is performed using a strobe, even if strong strobe light is reflected by a ceiling or a white wall, part of the reflected light often does not hit the human subject's eyes directly. Japanese Utility Model Laid-Open No. 55-105424 discloses a strobe body which is provided with a reflector in order to solve the drawbacks in which a photograph of a human subject cannot be obtained with vivid eyes. According to this publication, a part of the light emitted from the strobe is reflected by the above-mentioned reflector so that it is also guided to the eyes of a human subject.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a strobe device according to an embodiment of the present invention, and FIG. 2 shows the irradiation angle conversion adapter 3 and the reflection plate 5 by pulling out the pull-out knob 3a in FIG. FIG. 3 is a perspective view showing a state when the strobe main body 2 is moved to the outside.

As shown in FIG. 2, the above-mentioned insertion / removal opening 2 a is provided above the light emitting window 1 of the strobe body 2, and the irradiation angle converting adapter 3 is connected to the discharge tube 4 via the light emitting window 1 in FIG. A large number of pyramid-shaped portions are formed on the surface of a transparent material in order to diffuse the light generated by the light. FIG. 3 is a perspective view showing the components of the present invention. In this FIG. 3, pull-out knobs 3a are integrally provided on the left and right sides of the irradiation angle conversion adapter 3, respectively. . Further, between the left and right pull-out knobs 3a, an engaging convex portion 3b as the second engaging portion is provided integrally with the irradiation angle converting adapter 3. The irradiation angle converting adapter 3 is connected to the connecting portion 6b of the holding plate 6, and in order to hold the irradiation angle converting adapter 3 rotatably around the X axis in the drawing, the holding plate 6b Is used.

A wire-working spring 7 is located around the holding plate 6, and both ends 7 a of the spring 7 are inserted into the insertion portion 3 c of the adapter 3. A projecting portion 6c is provided on a part of the end surface of the holding plate 6 located on the opposite side of the connecting portion 6b, and the projecting portion 6c and the holding plate 6 located on both left and right sides in the drawing. The spring 7 is held around the holding plate 6 by the click protrusion 6a. The insertion portions 3c of the adapter 3 which are inserted into both ends 7a of the spring 7 are located toward the knob 3b from the X axis in the drawing, and slightly apart from the X axis. The "M-shaped" bending portion of the wire-working spring 7 is connected to a part of the end face located below the projecting portion 6c of the holding plate 6, and the elastic force of this bending portion causes the holding plate 6 to pass through. Then, a force that pulls the irradiation angle conversion adapter 3 toward the holding plate 6 is generated, and the linear spring 7 moves the irradiation angle conversion adapter 3 around the X axis in the drawing in accordance with the force. The force to rotate is generated.

The reflection plate 5 in FIG. 3 is formed with an engagement recess 5 a as the first engagement part for engaging with the engagement protrusion 3 b of the adapter 3, and its engagement The retaining claws 5b are provided on the left and right portions in the figure through the portion of the reflection plate 5 located on the side opposite to the combination recess 5a so as not to come off from the strobe body 2. The reflector 5 is a thin plastic plate made of white or silver in order to diffuse light in a wide direction, and is formed so as not to be elastically deformed and damaged even when an external force is applied. ing.

FIG. 4 is a cross-sectional view showing a state in which the irradiation angle conversion adaptor 3 and the reflection plate 5 are arranged in the storage chamber 2 b inside the strobe main body 2. In the same drawing, in the accommodation chamber 2b, the surface directions of the irradiation angle conversion adapter 3 and the holding plate 6 are located in a straight line, and the reflection plate 5 is placed on the irradiation angle conversion adapter 3 and the holding plate 6. In this state, the engaging projection 3b of the adapter 3 is engaged with the engaging recess 5a of the reflection plate 5. Reference numeral 8 in the figure is a concave reflecting mirror.

In order to use both the irradiation angle conversion adapter 3 and the reflection plate 5 as described above, the pull-out knob 3b in FIG. 1 is pulled out in the above-mentioned engagement, The irradiation angle conversion adaptor 3 is moved to the outside of the strobe body 2 through the insertion / removal opening 2a, and the holding plate 6 in FIG. 4 is also driven by the adapter 3 described above. At the time of pulling out the above-mentioned pull-out knob 3a, the engaging convex portion 3b of the irradiation angle converting adapter 3 maintains the engagement with the engaging concave portion 5a of the reflection plate 5 and passes through the insertion / removal opening 2a, so that reflection is caused. The plate 5 is also moved to the outside of the strobe main body 2 via the insertion / removal opening 2a. Therefore, the irradiation angle conversion adapter 3 and the reflection plate 5 can be moved to the outside of the strobe body 2 simply by pulling out the pull-out knob 3a.

When the connecting portion 6b of the holding plate 6 passes through the one surface Y including the surface of the light emitting window 1 in FIG. 4 from the rear side of the strobe body 2 during the above-mentioned pulling out, click in FIG. The protrusion 6a is locked in a recess formed in the inner wall of the strobe body, and the holding plate 6 is fixed to the strobe body 2 by this locking. The state of the holding plate 6 and the like at that time is shown in FIG. 5, and at the same time when the holding plate 6 is fixed, the irradiation angle changing adapter 3 passes through the connecting portion 6b of the holding plate 6 by the elastic force of the wire working spring 7. When the adapter 3 is rotated around the X-ray in FIG. 3 and brought into pressure contact with the light emitting window 1 of the strobe body 2 in FIG. 5 and the adapter 3 is rotated, the engaging convex portion 3b of the reflecting plate 5 is formed. It is pulled out from the engaging recess 5a.

When the irradiation angle converting adapter 3 is pressed against the light emitting window 1 in FIG. 5 by the elastic force of the line work spring 7, the reflecting plate 5 in the figure is pulled out in the direction of arrow P in the figure. During the pulling out, if the retaining claws 5b of the reflecting plate 5 in FIG. 3 are caught on the retaining portion located inside the strobe body 2, the pulling out of the reflecting plate 5 is stopped, and The position of the reflection plate 5 is held, and then stroboscopic photography is performed using both the irradiation angle conversion adapter 3 and the reflection plate 5 in FIG.

As described above, after the irradiation angle converting adapter 3 is pressed against the light emitting window 1, the reflecting plate 5 is pulled out, but after the pulling knob 3a is pulled out, it is inserted through the insertion / removal port 2a of the strobe main body 2. It is possible to halve the amount of pulling out the reflection plate 5 without pulling out the reflection plate 5 from the accommodation chamber 2b of the main body 2. Therefore, it is possible to save the trouble of withdrawing.

To insert the both 3 and 5 into the strobe main body 2 after completing the stroboscopic photography by using both the irradiation angle conversion adapter 3 and the reflector 5 described above, for example, the reflector shown in FIG. 5 is inserted into the accommodation chamber 2b of the strobe main body 2 through the insertion / extraction opening 2a, and when the insertion is completed, the reflection plate 5 is in a state in which a part thereof is placed on the holding plate 6 in FIG. Then, it is stored in the storage chamber 2b. Next, the irradiation angle converting adapter 3 is rotated about 90 degrees clockwise in the figure against the elastic force of the wire-working spring 7 in FIG. 5, and when rotated 90 degrees, the holding plate 6 is inserted. The irradiation angle conversion adapter 3 is inserted into the accommodation chamber 2b of the strobe main body 2 through the insertion / removal opening 2a while resisting the click force of the click protrusion 6a.

By the insertion, the click protrusion 6a is disengaged from the concave portion inside the strobe body 2 through the holding plate 6, and the holding plate 6 is also driven along the right direction in FIG. 5 to change the irradiation angle. Even when the engaging projection 3b approaches the insertion / removal opening 2a from the outside of the strobe main body 2 during the insertion of the adapter 3, the adapter 3 is continuously inserted. As a result of the insertion, when the above-mentioned engaging projection 3b passes through the insertion / removal opening 2a, the reflection plate 5 is formed of a thin practic plate as described above, so that it is positioned in the storage chamber 2b of the strobe main body 2. The front part of the reflecting plate 5 is pushed by the engaging projection 3a toward the notch 2c in FIG. 5 and elastically deformed, and when the irradiation angle converting adapter 3 is completely inserted, As shown in FIG. 4, the engaging protrusion 3b engages with the engaging recess 5a, and the front portion of the reflection plate 5 is restored. At this time, the height of the interior space of the accommodation chamber 2b is adjusted to accommodate the irradiation angle conversion adapter 3 and the accommodation space 2b in order to accommodate both of them 3 and 5 with the reflection plate 5 placed on the irradiation angle conversion adapter 3. It is not necessary to expand the reflective plate 5 beyond the total thickness thereof, and the height can be suppressed.

The state where the reflection plate 5 is inserted into the accommodation chamber 2b of the strobe main body 2 and then the irradiation angle converting adapter 3 is located outside the strobe main body 2 is shown in FIG. Show. At this time, flash photography can be performed using only the irradiation angle conversion adapter 3. After that, the irradiation angle conversion adapter 3 can be inserted into the accommodation chamber 2b of the strobe main body 2 in the same manner as described above, and at this time, the reflection plate 5 is elastically deformed by the engagement convex portion 3b. . Further, when the irradiation angle converting adapter 3 is completely inserted, the engaging projection 3b of FIG. 4 engages with the engaging recess 5a of the reflection plate 5 to restore the reflection plate 5 as described above. In addition, there is an advantage that the reflection plate 5 is not damaged.

Further, regarding the above-mentioned insertion, the state in which the reflection plate 5 and the irradiation angle conversion adapter 3 are sequentially inserted has been described, but the order can be changed to the following order. . The portion of the reflector 5 in FIG. 5 located outside the strobe body 2 is bent in the clockwise direction in the figure to hold that state, and the elastic force of the wire-working spring 7 and the click protrusions are held during the holding. The irradiation angle converting adapter 3 is inserted against the click force of 6a in the same manner as described above.

While the insertion is being performed, a part of the reflection plate 5 is pushed upward by the engaging convex portion 3a of the adapter 3 and elastically deformed, so that the irradiation angle conversion adapter 3 described above is completely removed. After the insertion, the bent portion of the reflection plate 5 is restored. After the restoration, the strobe main body 2 is laid on its back, and the state at that time is shown in FIG. According to this 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 it is inserted into the strobe body 2. The reflection plate 5 in FIG. 7 is inserted into the accommodation chamber 2b of the main body 2 through the insertion / removal opening 2a of the flash main body 2, and at this time, the portion of the reflection plate 5 that is in contact with the engaging convex portion 3b. Is pushed up toward the notch 2c in FIG. 5 by the engaging convex portion 3b and is elastically deformed. When the reflection plate 5 is completely inserted, the engagement projection 3a of FIG. 4 engages with the engagement recess 5b, and the reflection plate 5 is restored, as described above. At this time, the height of the inner space of the accommodation chamber 2b is set to the above-mentioned adapter for irradiation angle conversion in order to accommodate both the reflectors 3 and 5 with the reflection plate 5 placed on the irradiation angle conversion adapter 3. It is not necessary to expand the total thickness of the reflective plate 3 and the reflection plate 5 more than the total thickness, and the height can be suppressed.

The irradiation angle conversion adapter 3 and the reflection plate 5 can be sequentially inserted as described above, but as another insertion example, both the irradiation angle conversion adapter 3 and the reflection plate 5 are simultaneously inserted. The details are as follows. First, the irradiation angle conversion adapter 3 is rotated about 90 degrees clockwise in the figure against the elastic force of the wire-working spring 7 in FIG. 5, and when the adapter 3 is rotated 90 degrees, the engaging convex portion 3b is formed. To be engaged with the engaging recess 5a. At this time, the adapter 3 and the reflection plate 5 are overlapped and kept in that state, and inserted into the accommodation chamber 2b through the insertion / removal opening 2a of the strobe main body 2. By the insertion, the click protrusion 6a is disengaged from the recess of the inner wall of the strobe main body 2 via the holding plate 6, and the holding plate 6 is also driven along the right direction in FIG. After the above-mentioned insertion is completed, as shown in FIG. 4, the irradiation angle changing adapter 3 is placed in the accommodation chamber 2b with the reflection plate 5 placed thereon, and the accommodation chamber 2b is set in the inner space as described above. The height can be suppressed.

According to the above-described embodiment, not only the irradiation angle conversion adapter 3 and the reflection plate 5 are used, but also the pull-out knob 3a is pulled out and moved to the outside of the strobe body 2 as described above. It is possible to insert one of the irradiation angle conversion adapter 3 and the reflection plate 5 inside the strobe main body 2, and use the other left outside the strobe main body 2 for stroboscopic photography. 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 converting adapter 3, but as another example, as long as the following constitutional requirements are met, , You can also use it. Constituting requirements are: "Connect to the irradiation angle conversion adapter 3, hold the irradiation angle conversion adapter 3 rotatably, and pull out the irradiation angle conversion adapter 3 or insert the irradiation angle conversion adapter 3 to the irradiation angle conversion adapter 3. It is arranged to be mounted on the strobe body 2 in a driven manner. ”In addition to the holding plate 6 shown in FIG. Of course, such a holding member can also be used.

The wire-working spring 7 in FIG. 3 was formed so as to surround the periphery of the holding plate 6, but as another elastic member, for example, a wire-working spring having a short total length can also 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 hold the connection, and the side surface of the holding plate 6 on which the above-mentioned click protrusion 6a is located. The other end of the above-described wire-working spring is connected to a portion of the wire-working spring near the adapter 3, and the above-mentioned wire-working spring of the above-mentioned wire-working spring is provided around the X-axis in FIG. The irradiation angle converting adapter 3 may be rotated by elastic force (tensile force) so as to be pressed against the light emitting window 1 in FIG.

Further, it has been described that the irradiation angle conversion adapter 3 described above uses a plurality of pyramid-shaped portions formed on the surface of a transparent material in order to diffuse light. For this, a thin plate-shaped convex lens called a Fresnel lens provided with a saw-toothed portion may be used as the irradiation angle conversion adapter 3. In this case, if the flash firing angle is adjusted to a narrow angle according to the optical characteristics of the convex lens described above according to the telephoto lens attached to the body of the single-lens reflex camera, the above-mentioned narrow shooting of the telephoto lens is possible. It is well known that the strobe light can be narrowed down to the angle of view to increase the strobe guide number.
