本案は通称ビデオプロジェクタと呼ばれる投写型テレビ
ジョン受像機の調整装置に関するものである。[Detailed Description of the Invention] The present invention relates to an adjustment device for a projection television receiver commonly called a video projector.
投写型テレビジョン受像機には各種の方式があるが、そ
の中に投写型陰極線管に結ばれる映像を陰極線管の前面
にせり出した鏡面板に反射させて陰極線管の背後に立て
られているスクリーンに拡大投写するようにしたものが
ある。There are various types of projection television receivers, one of which is a screen that is placed behind the cathode ray tube and reflects the image transmitted to the projection cathode ray tube onto a mirrored plate protruding from the front of the cathode ray tube. There is a model that enlarges and projects the image.
これらのタイプのキャビネットでは、画像、音声９選局
、電源等に関連する調整器、切換スイッチ類はすべて陰
極線管を内蔵する箱体側に設けられている。In these types of cabinets, regulators and changeover switches related to the image, nine audio channel selections, power supply, etc. are all provided on the side of the box housing the cathode ray tube.
したがって、操作する際には離れた視聴位置からその都
度足を運ばなければならないし、特に画像に係る調整は
スクリーンに近接しすぎて調整しにくく不都合であった
。Therefore, each time an operation is performed, it is necessary to move from a distant viewing position, and in particular, it is difficult to adjust the image because it is too close to the screen, which is inconvenient.
本案はこのような問題を解決するために提案されたもの
で、各種調整器や切換スイッチ等の取付位置を操作しや
すい部分に設けるようにしたものである。The present invention was proposed in order to solve such problems, and the mounting positions of various regulators, changeover switches, etc. are provided in parts where they can be easily operated.
本案を以下実施例について図面に従って説明する。The present invention will be described below with reference to the drawings.
第１図は本案を適用した投写型テレビジョン受像機のキ
