[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a strobe device that is used as an artificial light source that illuminates a subject when taking a picture, and more particularly to a strobe device that uses an auxiliary optical member that controls an irradiation angle of light emitted from a light emitting unit.
[0002]
[Prior art]
Conventionally, a strobe device is well known as an artificial light source for illuminating a subject at the time of taking a photograph, and various means for changing the irradiation angle of the illumination light have been put into practical use.
For example, means for variably controlling the relative positional relationship between a light emitting unit composed of a reflector and a light source and an optical member disposed in the apparatus main body in front of the unit by moving at least one of the light emitting unit and the optical member Various irradiations such as means for variably controlling the relative positional relationship between the light source and the optical member by moving at least one of them, or means for mounting and using another auxiliary optical member in front of the optical member An angle variable means has been proposed or put into practical use.
[0003]
By the way, as a specific configuration for configuring the irradiation angle variable means using the auxiliary optical member different from the optical member arranged in the apparatus main body, the auxiliary optical member can be moved into the apparatus main body so as to be movable. An integrated structure (such as Japanese Utility Model Publication No. 55-162227, Japanese Utility Model Application Publication No. 6-2345, etc.) that is provided so as to be substantially integrated with the apparatus main body and is moved so as to be positioned in front of the light emission window when necessary Alternatively, an independent configuration in which the auxiliary optical member is a completely separate part independent of the apparatus main body and the independent auxiliary optical member is mounted on the apparatus main body and used when necessary is well known.
[0004]
[Problems to be solved by the invention]
Among the specific configurations of the irradiation angle variable means using the auxiliary optical member different from the optical member in the apparatus main body described above, the integrated configuration can be used immediately when it is desired to use the auxiliary optical member as compared with the independent configuration. In addition, the auxiliary optical member has an advantage of not being lost, but requires a space for forming a moving configuration for substantially integrating the auxiliary optical member so that the auxiliary optical member can be moved. If the size is increased, the cost may increase.
[0005]
On the other hand, although the independent configuration has disadvantages such as the possibility of loss compared to the integrated configuration, there is no need for a moving configuration for moving the auxiliary optical member, and the advantage that the main body shape of the apparatus can be reduced in size. Have.
However, the independent configuration has the following disadvantages when, for example, shooting using the auxiliary optical member is mixed with shooting not using the auxiliary optical member.
[0006]
That is, when the auxiliary optical member is not used, the independent configuration is to remove the auxiliary optical member from the apparatus main body and store the auxiliary optical member in an appropriate storage place such as a predetermined place or a photographer's clothes pocket. In such a state of use, every time it is used, a mounting operation from the storage location to the light emitting unit is required, and there is a disadvantage that it is still not good in terms of shooting operability.
[0007]
The present invention has been made in consideration of the disadvantages of the irradiation angle variable means according to the independent configuration described above. The first mounting means for forming the first mounting state in which the auxiliary optical member is mounted in front of the light emitting window portion; A strobe device provided with a second mounting means for forming a second mounting state in which the auxiliary optical member detached from the front of the light emitting window is mounted at an appropriate position of the apparatus main body including the light emitting unit excluding the front of the light emitting window. The purpose is to provide.
[0008]
[Means for Solving the Problems]
The strobe device according to the present invention is attached to and detached from the light emitting unit, and is attached to the front of the light emitting window of the light emitting unit to control the irradiation angle of light emitted through the light emitting window. A strobe device using a member, wherein the auxiliary optical member is mounted in front of the light emitting window portion to form a first mounting means for forming a first mounting state, and the auxiliary optical device detached from the front of the light emitting window portion. And a second mounting means for forming a second mounting state in which the member is mounted at an appropriate position of the apparatus main body including the light emitting unit excluding the front of the light emitting window.
[0009]
Accordingly, when the auxiliary optical member is not used, the auxiliary optical member can be attached to the apparatus main body via the second attachment means. That is, when the auxiliary optical member is not used, a predetermined place or a pocket of the photographer's clothes is used. As a result, even when shooting using the auxiliary optical member and shooting without using the auxiliary optical member are mixed, the auxiliary optical member is simply attached to and detached from the apparatus main body. It is possible to obtain a stroboscope with good operability that can set the use state or non-use state of members.

Have.
[0013]
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
(Embodiment 1)
FIG. 1 is a schematic external perspective view showing an embodiment of a strobe device according to the present invention, FIG. 2 is a schematic cross-sectional view of an auxiliary optical member denoted by reference numeral 8 in FIG. 1, and FIGS. FIG. 2 shows a schematic perspective view for explaining the operation of the embodiment.
[0014]
The apparatus main body 1 of the strobe device according to the present embodiment includes a main body 2 having an electric circuit configuration including a power source (not shown) and a shoe 3 attached to a camera mounting shoe (not shown). The light source 4 includes a light source (not shown), a reflector, and the like, and a light emitting unit 4 that emits light emitted from the light source to the outside from the light emission window 5.
A pair of locking recesses 6 and a pair of locking recesses 7 that function to attach an auxiliary optical member 8 (described later) to the light emitting unit 4 are formed on the side end surface of the light emitting unit 4.
[0015]
The auxiliary optical member 8 has a shape that covers the light emission window portion 5 of the light emission portion 4 and is positioned in front of the light emission window portion 5 to control the emission direction of the light emitted from the light emission window portion 5 and emit it to the outside. The optical part 8A and a pair of holding parts 8B formed integrally extending from the opposite ends of the optical part 8A in the direction of the light emission window part 5 have a substantially U-shaped cross section. Is formed.
[0016]
As shown in the schematic cross-sectional view of FIG. 2, a pair of locking projections 9 having the first holding structure is provided on the opposing surfaces of the pair of holding portions 8 </ b> B of the auxiliary optical member 8.
The pair of locking projections 9 as the first holding configuration can be fitted to the pair of locking recesses 6 and 7 formed on the side end surfaces of the light emitting unit 4 constituting the apparatus main body 1. It is configured. That is, the locking recesses 6 and 7 are provided as a second holding structure in the present invention with respect to the pair of locking protrusions 9 which are the first holding structure.
[0017]
Next, the operation of the strobe device of the present embodiment having the above-described configuration will be described with reference to the schematic external perspective views shown in FIGS.
FIG. 3 shows that a pair of locking projections 9 provided on the holding portion 8 </ b> B of the auxiliary optical member 8 is engaged with a locking recess 6 formed on the side end surface of the light emitting unit 4 constituting the apparatus main body 1. 1 shows a first mounting state in which the auxiliary optical member 8 is mounted on the apparatus main body 1 so that the optical section 8A is positioned in front of the light emitting window section 5 of the light emitting section 4. That is, the pair of locking projections 9 provided on the first holding portion 8B and the locking recess 6 formed on the side end surface of the light emitting portion 4 constitute the first mounting means in the present invention.
[0018]
Therefore, the light emitted from the light emission window portion 5 by the light emission operation of the light emitting portion 4 enters the optical portion 8A of the auxiliary optical member 8, and is emitted to the outside after being optically controlled by the optical portion 8A. For example, by setting the optical characteristic of the optical unit 8A as an optical characteristic for diffusing light incident through the light emitting window part 5, the irradiation angle is wider than the irradiation angle of light emitted only through the light emitting window part 5. Thus, it is possible to cope with photographing using a photographing lens having a shorter focal length.
[0019]
4 shows a state in which the auxiliary optical member 8 is once detached from the light emitting unit 4 from the state shown in FIG. The auxiliary optical member 8 is attached to the apparatus main body 1 in a state where the optical portion 8A is not positioned in front of the light emitting window portion 5 of the light emitting portion 4 by engaging with the locking recess 7 formed on the side end surface of the light emitting portion 4. The second wearing state is shown. That is, the pair of locking projections 9 provided on the holding portion 8B and the locking recess 7 formed on the side end surface of the light emitting portion 4 constitute the second mounting means in the present invention.
[0020]
Therefore, the light emitted from the light emission window portion 5 by the light emission operation of the light emission portion 4 is emitted outside without being controlled by the optical portion 8A of the auxiliary optical member 8.
As described above, the strobe device according to the present invention is in an optical control state using the auxiliary optical member 8 only by attaching / detaching the auxiliary optical member 8 to / from the apparatus main body 1 based on the first and second mounting means, or An optical non-control state that is not used can be set.
[0021]
Needless to say, the state in which the optical auxiliary member 8 shown in FIG. 4 is not used can be regarded as a non-use state of the strobe device itself.
In the illustrated embodiment, a pair of locking projections 9 and a pair of locking recesses 6 and 7 are employed as the first holding structure and the second holding structure forming the first and second mounting means, respectively. However, for example, depending on the setting of the elastic force of the holding portion 8B with respect to the light emitting portion 4, a combination of one locking projection and one locking recess can be used.
[0022]
Furthermore, although two sets of the locking recesses 6 and 7 are adopted as the second holding structure, for example, by setting the locking protrusion 9 to a predetermined shape such as a hemispherical shape, a set of predetermined shape such as a hemispherical shape is associated. The locking recesses 6 and 7 can be combined with the stopping recess.
[0023]
【The invention's effect】
As described above, according to the present invention, when the auxiliary optical member is not used, the auxiliary optical member can be attached to the apparatus main body via the second attachment means, that is, when the auxiliary optical member is not used, It is not necessary to store in a special storage location such as a place or a photographer's clothes pocket, and as a result, even when shooting using the auxiliary optical member and shooting not using it are mixed, This has the effect of providing a stroboscope with good operability that can set the use state or non-use state of the auxiliary optical member only by the loading / unloading operation.
