[0031]
The camera shoe adapter of this embodiment configured as described above has many patterns
at the set position of the shoe arm 3 as shown in FIG. 7, that is, the external microphone can be
placed at any position.
[0032]
Next, the holder belt 25 provided on the shoe arm 3 will be described.
The holder belt 25 has a length of about one and a half turns around the shoe arm 3, and the
base end of the holder belt 25 is fixed to the inner side surface of the shoe arm 3 by a fixing
member 26.
As a material of the holder belt 25, a durable cloth material is suitably used.
[0033]
A pair of surface fasteners (so-called velcro tapes) 27a and 27b are attached to the overlapping
portion of the base end portion and the tip end portion of the holder belt 25. The holder belt 25
is mounted on the shoe arm 3 by the surface fasteners 27a and 27b. It is to be fastened in a
wound state.
[0034]
Then, as shown in FIG. 8, by bundling the cords 105 of the external microphone by the holder
belt 25 and fixing them together with the surface fasteners 27a and 27b, the cords 105 do not
go into a state of dangling, and the shoes are surely shoe As it is fastened to the arm 3, it does
not interfere with shooting.
[0035]
In addition, as shown in FIG. 9, a battery box 108 attached to an external microphone can be
fixed to the holder belt 25.

That is, the battery box 108 incorporates a battery for supplying power to the external
microphone, and has a hook portion 109 for hooking the holder belt 25 on the back side.
Reference numeral 110 denotes a power on / off switch.
[0036]
In the case of this battery box, the cord of the external microphone and the cord of the battery
box are bundled together and fastened together by the holder belt 25, and the hook portion 109
of the battery box 108 is hooked and fixed to the holder belt 25 thereon.
By fixing the battery box 108 to the holder belt 25 in this manner, the battery box 108 does not
get in the way of shooting, and the switch 110 of the battery box 108 can be easily turned on /
off and easily viewed. .
[0037]
The holder belt 25 also functions as a protection member for protecting the video camera body
100 from the shoe arm 3.
That is, even if the camera shoe adapter 1 has a backlash and the shoe arm 3 hits the video
camera main body 100, the shoe arm 3 does not directly hit the video camera main body 100,
but hits via the holder belt 25. Therefore, the video camera body 100 is protected by the holder
belt 25 and the video camera body 100 is not scratched.
[0038]
FIG. 10 shows an example in which a hook is used in place of the surface fastener of the above
embodiment as the fastening means of the holder belt 25. As shown in FIG.
01-05-2019
9
That is, in this embodiment, a concave hook member 28a is provided on the base end side of the
holder belt 25 and a convex hook member 28b is provided on the tip end side of the holder belt
25. The convex hook member 28b is concaved. The cord of the external microphone is fastened
by being fitted to the side hook member 28a.
As described above, this embodiment using the hook as the fastening means of the holder belt 25
has a feature that a more secure feeling of fastening can be obtained.
[0039]
Further, as shown in FIG. 11, by using a longer holder belt 25, a thick cord can be bound.
Further, by using the holder belt 25 having a width smaller than that shown in the drawing, the
cords can be easily bound.
[0040]
In addition, it is preferable to set the holder belt 25 at a lower position (a position away from the
shoe 6) than an upper portion of the shoe arm 3 (a position near the shoe 6). 12 shows the case
where the holder belt 25 is provided on the upper part of the shoe arm 3, and FIG. 13 shows the
case where the holder belt 25 is provided on the lower part of the shoe arm 3. , B is in a state
where the external microphone 104 is removed from the shoe 6 of the shoe arm 3.
[0041]
As apparent from the comparison of the two figures, when the external microphone 104 is
removed from the shoe 6 with the cord 105 held by the holder belt 25, the cord 105 is short
when the holder belt 25 is at the top (FIG. 12). Although there is no margin, when the holder belt
25 is at the bottom (FIG. 13), the cord 105 has a long margin, that is, the degree of freedom of
the external microphone 104 is large. Therefore, it is advantageous when it is desired to remove
only the external microphone 104 from the shoe arm 3 with the cord 105 fixed to the holder belt
25 and check the position of the switch of the external microphone.

[0042]
As mentioned above, although the Example of this invention was described, of course, this
invention is not limited to the structure of these Examples. Further, it goes without saying that
the present invention is not limited to the case of attaching an external microphone to a video
camera, and can be widely used in various other applications.
[0043]
As is apparent from the above description, the camera shoe adapter of the present invention is
provided with a holder for holding a cord such as an external microphone, so that the surplus
cord does not disturb the photographing, and the cord There is no risk of accidental reflections
or the occurrence of noise when the code strikes the camera body. In addition, the cord can be
held by the holder to give a beautiful impression as it looks.
