Abstract

PURPOSE:To eliminate the need to provide one more magnet for operation inhibition during the consumption of electric power, by providing a permanent magnet which attracts a lock lever locking a prime power member controlling automatic focusing operation and the opening of a shutter. CONSTITUTION:A magnet 28 is energized momentarily with a release and the rotation of a lever 23 disengages a hook part 23a from the bent part 15f of a prime power member 15. Consequently, the prime power member slides to rotate a ring 10 which regulates the rotation of an extension ring 2 and when a magnet 8 is operated by a focus detection signal, lens extension is stopped. The prime power member further moves and the lever 23 is reset by a cam edge 15d and held by the magnet 28 to stop the movement of an auxiliary member 29 by the engagement between the hook part 23a and bent part 29c. A pin 17a is disengageded at a position right before a stop position to open a shutter and auxiliary member runs by feeding a current to the magnet 28 to close the shutter
