Claims (3)

  1. 一種投射型影像顯示裝置，是將由顯示元件形成的影像由投射透鏡擴大投射，具備將前述投射透鏡朝與投射光的光軸垂直的2軸方向移動的透鏡移行機構，該透鏡移行機構，是具有：將前述投射透鏡朝垂直方向移動的第1可動基座、及朝水平方向移動的第2可動基座、及將該第1可動基座驅動的第1致動器、及將該第2可動基座驅動的第2致動器，該第1可動基座是將朝垂直方向配置於固定構件側的2條的軸作為導引構件進行滑動，該第2可動基座是將朝水平方向配置於該第1可動基座的2條軸作為導引構件進行滑動，對於前述第1可動基座的導引構件也就是2條軸，使從前述固定構件的背面側與該軸抵接的方式插入修正螺栓，藉由調整該修正螺栓的插入量來修正前述投射透鏡的光軸的傾斜及該投射透鏡的位置偏離。
  2. 如申請專利範圍第1項的投射型影像顯示裝置，其中，在前述第1、第2可動基座中，各別設置前述軸貫通的2個軸孔，該2個的軸孔之中接近前述第1、第2致動器的軸孔是與前述軸大致同徑，另一方的軸孔是比前述軸的徑更大。
  3. 如申請專利範圍第1項的投射型影像顯示裝置，其中， 前述第1、第2致動器是為了將前述第1、第2可動基座驅動，藉由各導螺桿的旋轉將驅動螺帽推進，使與該驅動螺帽連結的前述第1、第2可動基座移動，且在該驅動螺帽的連結面形成突起部。
