とを特徴とするレンズ駆動装置付きシヤツター。 The driving ring is rotated forward and backward by a stepping motor energized by a command from the sequential operation control circuit of the camera. a lens setting ring that is interlocked with the photographic lens so as to set the shutter blade, a lens stop lever that releasably locks the lens setting ring in the normal rotation position, and an opening/closing lever that controls the opening degree of the shutter blade. an opening/closing lever that releasably locks the opening/closing lever in the shutter blade closed position during normal rotation of the drive ring; and an opening/closing lever that releases the locking of the opening/closing lever when the driving ring rotates in the reverse direction. An opening locking pawl provided on the opening locking lever and a cam protrusion provided on the drive ring cooperate to enable the shutter blades to be moved to the open position, and a cam protrusion provided on the drive ring is formed on the opening/closing lever to prevent the drive ring from reversing. an inclined cam formed on the opening/closing lever that engages with the opening/closing lever operating protrusion of the drive ring to position the shutter blades in the small aperture position; and when the drive ring is set in the small aperture position. The opening/closing lever is rotated in the forward direction again by a command from the sequential operation control circuit so that the opening/closing lever can be rotated to the fully open position of the shutter blade, and the automatic exposure control circuit of the camera is activated by a trigger signal from the sequential operation control circuit. After the exposure time based on the signal, the drive lever is reversed again to actuate the opening/closing lever to the shutter blade closed position, and the opening/closing lever locks the shutter blade in the closed position, and finally, the drive ring is further closed. 1. A shutter with a lens drive device, characterized in that the shutter is configured to be able to operate sequentially so that the lens setting ring is returned to its initial position by reverse rotation.
