Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a strobe having a built-in reflector that can be opened and closed when not in use and can be closed when not in use.

“Prior Art and Its Problems” In recent years, an increasing number of zoom lenses have a macro function that enables close-up photography.

However, when using macro photography with a conventional strobe, the amount of strobe light is too high and overexposure is likely to occur, and the optical axis of the strobe and the shooting lens are too far apart from the distance to the subject. There was also the problem that shadows appeared strongly.

In addition, since the strobe has a small light emitting source, shooting with a strobe will result in a photograph with strong light and shade and shadows due to the unevenness of the subject itself and the difference in the distance to the strobe. Therefore, in recent years, many stroboscopic devices have a light emitting unit housing formed so as to be rotatable in the elevation direction and have a bounce function capable of indirectly illuminating a subject. According to this bounce photography, the shadow is weaker and a soft impression is given as compared with the case where the subject is directly illuminated with a strobe.

However, this bounce shooting is possible when there is a reflector such as the ceiling above, but it is not possible outdoors where there is no reflector.

As means for weakening or reducing the brightness and shadow of a subject in flash photography, there is a means for irradiating a strobe toward a reflector and illuminating the subject with the light reflected by the reflector. However, conventionally, the strobe and the reflector are separate bodies, and it is inconvenient to carry and set the reflector separately from the strobe.

"Purpose of the invention" This invention was made based on the above awareness of the problem.
Even with a conventional strobe, you can easily limit the amount of light during macro shooting,
It is an object of the present invention to provide a strobe that can remove shadows and can achieve the same effect as indirect illumination.

[Outline of the Invention] The present invention that achieves the above-mentioned object is a strobe device having a light-emitting unit housing that can be elevated and lowered with respect to a strobe body, and can reflect strobe light emitted from the light-emitting unit housing in a deployed state. A reflective umbrella that can be opened and closed, and a storage case that supports the reflective umbrella in an unfolded and unfolded state at a reflective position protruding from the light emitting unit casing, the storage case including the reflective position and the It is characterized in that it is formed so as to be able to store a closed reflector and to be movable between a storage position that forms the appearance of the light emitting unit casing.

The reflective umbrella 30 is made of a rigid thin plate material and has a folding line.
It is formed so that it can be folded freely from 31a, 31b, 31c, 31d, and can be folded in a predetermined manner from each fold line so that it can be folded into a small stack of nine sheets. On the front surface of the reflective umbrella 30, a reflective surface 32 that has been subjected to reflective processing is formed. Also a reflective umbrella 30
A connecting sheet 33 is attached between the back surface of the portion surrounded by the folding lines 31a, 31b and 31d and the inner surface of the storage case 40, and is attached to the storage case 40 by the connecting sheet 33.

Next, the configuration of the storage case 40 will be described with reference to FIGS. The storage case 40 has a box-like shape with a planar outline substantially equal to the outline of the light-emitting unit housing 20 and an open lower surface, and two dovetail grooves 41, 41 are formed on the rear side wall.
Ribs 44 having grooves 45 are formed near both outer sides of each dovetail groove 41 in the storage case 40, and ribs 42, 42 having grooves 43 are formed at a front portion facing each rib 44. .

Guide rails 24, 24 parallel to each other are formed on the upper surface of the light emitting unit housing 20 adjacent to the surface having the condenser lens 21, and dovetail grooves 41 are fitted to the guide rails 24, respectively. By fitting the dovetail groove 41 and the guide rail 24, the storage case
40 is a guide rail that is connected to the light-emitting unit housing 20.
Guided slidably along 24. The rear portion of the guide rail 24 is formed up to the corner of the light emitting unit housing 20, but the front portion is cut off in the middle. And each guide rail 24
Pins 25 that fit into the grooves 43 or the grooves 45, respectively, are provided near the front end of the.

Next, a method of use, an operation and an operation of the present embodiment having the above configuration will be described. In normal use, the light is emitted in the state shown in FIG. In this state, in the storage case 40, the dovetail groove 41 is fitted to the guide rail 24, the groove 43 is fitted to the pin 25, and the holding case 40 is held on the upper surface of the light emitting unit housing 20, and is integrated with the light emitting unit housing 20. Thus, the appearance of the light emitting unit housing 20 is formed.

When using the reflector 30, first, the light emitting unit housing 20 is lifted up by about 90 °, and the surface of the condenser lens 21 is directed upward. A click stop member (not shown) is provided between the projecting piece 12 and the shaft 14 so that the click stop member can be stopped at the above-mentioned elevation position.
