Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hood for a slave unit to which an external strobe is attached.
[0002]
[Prior art]
In general, when the camera's flash is insufficient, an external strobe is used. The external strobe has a function to slave in response to the flash of the camera, but does not detect the strobe light and the sun because the light is similar.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a hood for a slave unit in which a light receiving element can be reliably detected and strobed by covering the light receiving element with a hood.
[0004]
[Means for Solving the Problems]
Means for solving the problems according to the present invention comprises a light receiving element provided on a housing having a strobe function, and a funnel-shaped hood body attached to the light receiving element and having a light receiving surface disposed on a base. The means according to claim 2 is that the hood is attached to the light receiving element in a plug-in structure, and the means according to claim 3 is that the hood is screwed to the light receiving element. The means according to claim 4, wherein the hood is preferably each colored in black, and provides a hood for a slave unit that can reliably realize a slave when sunlight or the like hits a light receiving element. Is what you do.

BEST MODE FOR CARRYING OUT THE INVENTION
1, 2 and 3 relate to one embodiment of the present invention. FIG. 1 is a perspective view, FIG. 2 is a schematic sectional view, and FIG. 3 is a view of a hood main body. Reference numeral 1 denotes a strobe housing in which a light emitting circuit is incorporated so that the light can be issued from the issuing unit 2. A hood main body 4 that hoods the light receiving element 3 is disposed on a side portion of the housing 1. The hood main body 4 is configured to be detachable from the light receiving element 3 by an insertion structure or a screw-in structure. The hood body 4 has a funnel-shaped structure in which external light, for example, sunlight, does not directly hit the light receiving element 3. As a result, there is no case where the slave does not stop. 5 is a slit.
[0006]
In the case of attachment, when the small opening side of the hood main body 4 is inserted into the light receiving element 3 side, the slit 5 is formed so that it can be easily inserted, external light coming from an unexpected direction can be blocked, and the slave can reliably operate. Is
