Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lens barrel enabling a high speed of a manufacturing process and capable of performing a reliable lock operation of a shake correction device.SOLUTION: A lens barrel includes: an image formation optical system; a shake correction device having a movable member 112 for holding a correction lens 111, a base member 121 for movably supporting the movable member 112, and a plurality of correction driving means 132, 113 for driving the movable member 112; a lock mechanism 151 held by the base member 121 and having an engaging pin 202 and an engaging pin driving means; a lock control circuit for controlling a lock operation; contact coordinates of the engaging pin 202 on the planer surface vertical to an optical axis, the engaging pin detected by inserting the engaging pin 202 into an engaging hole 201 so as to make the engaging pin 202 and the engaging hole 201 contacted by driving the movable member 112 in a predetermined direction; and memory means for recording engaging pin insertion coordinates obtained by a drive fluctuation of the engaging pin 202 and the maximum relative error amount calculated from a position detection accuracy of the movable member 112.SELECTED DRAWING: Figure 3
【課題】製造工程の高速化を可能とし、ブレ補正装置の確実なロック動作を行うことのできるレンズ鏡筒を提供する。【解決手段】結像光学系と、補正レンズ111を保持する可動部材112と、可動部材112を移動可能に支持するベース部材121と、可動部材112を駆動する複数の補正駆動手段132,113とを有するブレ補正装置と、ベース部材121に保持され、係止ピン202と、係止ピン駆動手段とを有するロック機構151と、ロック動作を制御するロック制御回路と、係止ピン202を係止孔201に緩挿し、可動部材112を所定方向に駆動させて係止ピン202と係止孔201とを接触させることで検出される、光軸と垂直な平面上の係止ピン202の接触座標と、係止ピン202の駆動バラツキと可動部材112の位置検出精度から算出される最大相対誤差量とから求められる係止ピン緩挿座標を記録するメモリ手段とを有する。【選択図】図3 |
