発明の名称 画像投映装置  Title of the invention Image projection device
技術分野  Technical field
本発明は、 単一の受像管を使用した画像投映装置に関するもの ίある c  The present invention relates to an image projection apparatus using a single picture tube.
背景技術  Background art
従来、 カ ラ ーの画像投映装置は受像管が 2管または 3管配置さ れていたので、 投映距離等に応じて受像管を制御する制御機構が 必要となり、 大形であった。 また、 画像投映装置に信号を出力す る、 例えば V T Rは別体構成のものを使用していた。 したがって 画像投映装置を使用する時は V T R等が必要となるため、 双方を 搬送しなければならず、 搬送性、 操作性が いという問題があつ た。  Conventionally, color image projection devices have been arranged with two or three picture tubes, so a control mechanism for controlling the picture tubes according to the projection distance and the like was required, and was large. In addition, a signal is output to an image projection device, for example, a VTR having a separate configuration is used. Therefore, when an image projection device is used, a VTR or the like is required, so that both have to be transported, and there is a problem that transportability and operability are poor.
そこで、 本出願人は先に画像投映装置の受像管を、 例えばビー ムイ ンデッ クス型カ ラ一テレビ受像管、 すなわち、 単一の受像管 で構成し、 画像投映装置の操作性向上、 小形化を計った装置を提 案した (特開昭 55- 80983号等) 。  Therefore, the present applicant firstly configured the picture tube of the image projection device with, for example, a beam index type color television picture tube, that is, a single picture tube, to improve the operability and downsizing of the image projection device. A device was proposed (Japanese Patent Laid-Open No. 55-98398, etc.).
すなわち例えば赤、 緣、 青の色螢光体ス ト ライ プが水平走査方 向に所定ピッチで繰り返し配列され、 これらの各色螢光体ス ト ラ ィ プの間に光吸収体ス ト ラィ プが設けられると共に、 この光吸収 体ス ト ライ プの例えば 1本おきに螢光体等によるィ ンデッ クスス ト ライ プが設けられる。 そしてこれらを単一ビームで走査すると 共に、 ィ ンデシ ク スス ト ライ プの螢光をフォ トダイォー ド等で検 出し、 この検出信号を 2遁倍した信号により赤、 緣、 青の映像信 号を順次切換えられた映像信号にて走査ビームを変調してカラー 再現を行うようにした、 いわゆるビームィ ンデックス型カラー受 像管が提案されている。  That is, for example, red, blue, and blue color phosphor stripes are repeatedly arranged at a predetermined pitch in the horizontal scanning direction, and a light absorber stripe is interposed between these color phosphor stripes. In addition, an index strip made of a phosphor or the like is provided at every other light absorber strip, for example. These are scanned with a single beam, and at the same time, the fluorescence of the index stripe is detected by a photo diode or the like, and the red, green, and blue video signals are obtained by multiplying the detection signal by two times. A so-called beam index type color picture tube has been proposed in which a scanning beam is modulated by a video signal that is sequentially switched to reproduce color.
このようなビームィ ンデックス型カラー受像管によれば、 シャ  According to such a beam index type color picture tube,
WIFO Α ドーマスク等を用いないので同一ビーム量で輝度が向上し、 極め. て高い輝度が得られる。 WIFO Α Since a mask is not used, the brightness is improved with the same beam amount, and extremely high brightness can be obtained.
そこでこのようなビームィ ンデフクス型カ ラ一受像誉を用いて 画像投映装置を形成することが提案された。 これによれば、 単一 5 の受像管にて極めて明るい投映画像を得ることができる。  Therefore, it has been proposed to form an image projection device using such a beam-in-deflux type color image receiving system. According to this, an extremely bright projected image can be obtained with a single 5 picture tube.
そしてこの場合に、 受像管が単一であるので、 従来の 2管、 3 管のものと比べて極めて小型、 軽量にでき、 可鎩型の装置を搆成 することができる。 また受像管が単一であるので、 従来のような レンズの光軸を一致させるなどの必要がなく 、 任意の距離からス 10 ク リ ーンへの投映を行う ことができるようになる。  In this case, since there is a single picture tube, the size and weight of the device can be made extremely small and light as compared with the conventional two or three tubes, and a portable device can be formed. In addition, since there is a single picture tube, there is no need to make the optical axes of the lenses coincide with each other as in the past, and it is possible to perform projection onto the screen from an arbitrary distance.
しかしながらこの場合においても、 画像投映装置と V T R等は ' 別体であるので、 鎩送性、 操作性が悪いという問題は解消されな い。  However, even in this case, since the image projection device and the VTR are separate units, the problem of poor transportability and operability is not solved.
