動焦点調節カメラの誤動作防止装置。In an automatic focusing camera that adjusts the focus by adjusting the amount of rotation of the lens barrel in stages by attracting or releasing two locking members to a magnet, the locking members are attached to the focus adjustment mechanism. A spring member that urges the magnet in the direction of adsorption and an activation delay member that locks the spring member are provided, so that the operating state of the magnet is stabilized even after the spring member is released from the release member. A malfunction prevention device for an automatic focusing camera, characterized in that the spring member is locked by an actuation delay member until the release member is pressed down a predetermined amount, and the lock by the actuation delay member is released.
