【考案の詳細な説明】
本考案はビデオテープレコーダ（ＶＴＲ）用ブースター
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a booster device for a video tape recorder (VTR).
従来のＶＴＲの入力信号を増幅する為のブースター装置
に於てはＶＴＲ本体から電源の供給を受けて動作しアン
テナからの入力信号を増幅しＶＴＲ及びテレビに供給す
るようにしたものが゛多い
然しなからこのような装置ではＶＴＲを断としたときは
ブースターが動作しなくなるため、テレビへのアンテナ
入力信号の供給が断たれる欠点があった。Many conventional booster devices for amplifying VTR input signals operate by receiving power from the VTR, amplify the input signal from the antenna, and supply it to the VTR and TV. Therefore, in such a device, when the VTR is turned off, the booster stops operating, so the supply of antenna input signals to the television is cut off.
本考案はこのような欠点を除去しＶＴＲを使用しないと

が附勢されたとき開くリレー接点とより戊ることを特徴
とする。The present invention eliminates these drawbacks and makes it possible to watch television on a television even when the VTR is not in use. The present invention is characterized by comprising a relay coil operated by voltage from the power supply, and a relay contact connected between the antenna and the output terminal of the booster and opened when the relay coil is energized.
以下図面によって本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to the drawings.

し、このリレー接点５はリレーコイル２の作動中は開か
れるようにする。In the present invention, a relay coil 2 is connected between both ends of a DC power supply terminal 1 of a VTR, and the voltage of this power supply terminal 1 is supplied to a booster 3 as its operating voltage, and an antenna terminal 4 is connected to an input terminal of the booster 3. A relay contact 5 is inserted between the antenna terminal 4 and the output terminal of the booster 3, and the relay contact 5 is opened while the relay coil 2 is in operation.
本考案ＶＴＲ用ブースター装置は上記のような構成であ

圧がリレーコイル２に印加されている状態ではアンテナ
端子４からの入力信号はブースター３によって増幅され

に供給されるが、ＶＴＲが使用されず、従って電源端子
１の電圧がリレーコイル２に印加されない状態ではリレ
ー接点５が閉じ、アンテナ端子４からの入力信号は直接
端子６に印加されるようになる。Since the VTR booster device of the present invention has the above-described configuration, when the VTR is used and the DC power voltage is applied to the relay coil 2 as shown in the drawing, the input signal from the antenna terminal 4 is transmitted by the booster 3. It is amplified and supplied to the input terminal of the VTR via the output terminal 6 of the booster device, but when the VTR is not used and therefore the voltage at the power supply terminal 1 is not applied to the relay coil 2, the relay contact 5 closes and the antenna terminal The input signal from 4 is applied directly to terminal 6.
即ちＶＴＲの使用、不使用にかかわらず何れの場合でも
、テレビにアンテナよりの入力信号を加えることができ
る大きな利点がある。That is, regardless of whether a VTR is used or not, there is a great advantage in that the input signal from the antenna can be added to the television.
