固定ベースと、固定ベースに対して水平方向に移動自在に支持された水平可動ベースと、水平可動ベースに対して垂直方向に移動自在に支持された垂直可動ベースと、水平可動ベース及び垂直可動ベースの移動面に対して光軸が略直交すると共に、水平可動ベースまたは垂直可動ベースに取り付けられた投写レンズと、水平可動ベースまたは垂直可動ベースを夫々所定量移動させる操作手段と、固定ベースと水平可動ベースまたは垂直可動ベースとの間で形成され、投写レンズを中央位置から所定範囲内で垂直方向に移動させた場合には、投写レンズの水平方向の移動量を前記所定量まで移動可能にすると共に、投写レンズを中央位置から所定範囲外まで垂直方向に移動させた場合には、投写レンズの水平方向の移動量を前記所定量より少なくなるように規制する移動規制手段とを備えていることを特徴とするレンズシフト機構。 A fixed base, a horizontal movable base supported so as to be movable in a horizontal direction with respect to the fixed base , a vertical movable base supported so as to be movable in a vertical direction with respect to the horizontal movable base, and a horizontal movable base and a vertical movable base The projection surface mounted on the horizontal movable base or the vertical movable base, the operating means for moving the horizontal movable base or the vertical movable base by a predetermined amount, the fixed base and the horizontal Formed between the movable base and the vertical movable base, and when the projection lens is moved vertically within a predetermined range from the center position, the horizontal movement amount of the projection lens can be moved to the predetermined amount. At the same time, when the projection lens is moved vertically from the center position to outside the predetermined range, the horizontal movement amount of the projection lens is less than the predetermined amount. Lens shift mechanism, characterized in that it comprises a movement restricting means for restricting so. 光源から出射された光を表示デバイスにより光変調し投写レンズにて映像投写する投写型映像表示装置において、前記請求項１記載のレンズシフト機構を備えていることを特徴とする投写型映像表示装置。 2. A projection-type image display device that modulates light emitted from a light source by a display device and projects an image with a projection lens, comprising the lens shift mechanism according to claim 1. .
