ズシヤツタ装置。[Claims for Utility Model Registration] A shutter blade, a drive means for opening the shutter,
The shutter opening/closing lever includes a first engaging portion that moves between a first position and a second position in conjunction with the shutter opening driving means, and a shutter opening/closing lever. It is the pivot center of the opening/closing lever, and is linked to the electromagnetic device to move the third and fourth positions.
a movement axis that moves between the fifth position and the sixth position;
a second engaging portion that moves between positions to open and close the shutter blade, and when the electromagnetic device restrains the moving shaft in the third position, the shutter opening driving means When the first engaging part moves from the first position to the second position, the second engaging part moves from the first position to the second position.
When the engaging part moves from the fifth position to the sixth position to open the shutter blade, and then the electromagnetic device moves the moving shaft from the third position to the fourth position, the second engaging part In the lens shutter device, the electromagnetic device includes a fixed part fixed to a fixed object and a movable part that moves with respect to the fixed part. The lens shutter device is characterized in that the moving shaft is directly supported on the movable part, and the movable part moves the moving shaft between the third position and the fourth position by electromagnetic action.
