シヤツタ装置において、 透過又は遮光が行われて信号が発生せしめられ
るようになつている検出部材と、 上記レンズ駆動機構のレンズ駆動リングと、 該レンズ駆動リングの回動が所定位置にある時
その回動に連動して上記検出部材の透過又は遮光
を行う揺動部材と、 上記シヤツタ制御機構のシヤツタ羽根と、 を有していて、 上記揺動部材により透過又は遮光によつて上記
検出部材がレンズ位置情報信号を発生し、且つそ
の後、上記シヤツタ羽根の一部により上記検出部
材の透過又は遮光が行われてシヤツタ羽根開放位
置信号を発生する、 ことを特徴とするシヤツタ装置。[Scope of Claim for Utility Model Registration] A shutter device equipped with a lens drive mechanism and a shutter control mechanism, comprising: a detection member configured to transmit or block light to generate a signal; and a lens of the lens drive mechanism. a drive ring; a swinging member that transmits or blocks light from the detection member in conjunction with the rotation of the lens drive ring when it is at a predetermined position; and a shutter blade of the shutter control mechanism. The detection member generates a lens position information signal when the light is transmitted or blocked by the swinging member, and then the light is transmitted or blocked by the detection member by a part of the shutter blade, and the shutter blade is opened. A shutter device that generates a position signal.
