Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a shutter device that can increase a speed of consecutive shots.SOLUTION: A shutter device (202) of an electronic front curtain system comprises: a first blade group (61) that moves in a first direction to block incident light toward an opening (1z); a second blade group (62) that moves in a second direction opposite to the first direction to block the incident light toward the opening; a first blade lever (7) that moves the first blade group; a second blade lever (8) that moves the second blade group; a first driving lever (3) that drives the first blade lever to cause the first blade group to close the opening; a second driving lever (4) that drives the second blade lever to cause the second blade group to close the opening; a first cam member (43) that charges the first driving lever; and a second cam member (44) that charges the second driving lever. After the first driving lever is charged by the first cam member, the second driving lever charged by the second cam member is separated from the second cam member.SELECTED DRAWING: Figure 2(b)
【課題】連写速度を向上させることが可能なシャッタ装置を提供する。【解決手段】電子先幕方式のシャッタ装置(202)であって、開口(1z)への入射光を遮光するように第一方向に移動する第一羽根群(61)と、開口への入射光を遮光するように第一方向とは逆の第二方向に移動する第二羽根群(62)と、第一羽根群を移動させる第一羽根レバー(7)と、第二羽根群を移動させる第二羽根レバー(8)と、第一羽根群が開口を閉じるように第一羽根レバーを駆動する第一駆動レバー(3)と、第二羽根群が開口を閉じるように第二羽根レバーを駆動する第二駆動レバー(4)と、第一駆動レバーをチャージする第一カム部材(43)と、第二駆動レバーをチャージする第二カム部材(44)とを有し、第一駆動レバーが第一カム部材によりチャージされた後、第二カム部材によりチャージされた第二駆動レバーは第二カム部材から離れる。【選択図】図2(b) |
