The present invention relates to a coupler type receiving unit that can be used.

[Conventional technology]

Conventionally, in camera-integrated VTRs, the back and
There was a device that made it possible to record ground mini-sick (BGM) manually from an external audio input terminal at the same time as recording. In addition, in order to record the audio of the wireless microphone Karu at the same time, a separate receiving unit is required.
Audio signals were manually input from the receiving unit to the external audio input terminal on the camera body via a connection cord.

[Problem to be solved by the invention]

However, in the above case, it was necessary to separately prepare a receiving unit for the radio or wireless microphone and a connection cord for connecting these to the camera body. Further, there are problems in that it is troublesome to carry these devices around separately from the camera body, and it is also troublesome to connect them to the camera body.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coupler type receiving unit that is convenient to carry, can be easily connected to the camera body, and can also share the power source of the camera body. purpose.

[Means to solve problems]

In order to achieve the above object, the present invention provides a coupler type receiving unit that is detachably attached between a battery attachment part of a camera and a battery externally attached to the battery attachment part, the coupler type reception unit a connecting means for guiding the power source of the battery to the camera; a receiving antenna; a receiving section that demodulates the signal received by the receiving antenna using the power source of the battery; A connector section that outputs to an external audio input terminal,
It is characterized by having the following.

[Effect]

According to the present invention, since it is detachably attached between the battery attachment part of the camera and the battery, it can be carried along with the camera body, making it convenient to carry. Also, since the camera body's battery is shared, there is no need to prepare a separate power source. Furthermore, since it is attached to the camera body, it can be easily connected to an external audio input terminal on the camera body side.

〔Example〕

Preferred embodiments of the coupler type receiving unit according to the present invention will be described in detail below with reference to the accompanying drawings.

It is now possible to supply power to TR2G.

Further, the receiving circuit 17 in the receiving unit 10 is configured to receive power from the battery 30 via the line A1B and the line CSD.

As shown in FIG. 2, this receiving unit 10 receives, for example, a wireless microphone 18 or an FM
In the FM receiving unit that receives waves, a receiving circuit 17 receives the FM waves manually through an antenna 16. The receiving circuit 17 is
