Abstract
Abstract An arrangement for removing a disk-shaped recorded medium from compartments of a magazine, in which a member is movable up and down along a side of the magazine from which the disk-shaped recorded medium is to be removed. The movable member is driven only on a first side thereof. A spring supports the movable member only on a second side which lies opposite to the first side of the movable member. The spring is in the form of a torsion spring with a long arm, and has a resiliency that is independent of the distance traveled by the spring within its range of travel. The long arm on the torsion spring is used to support the movable member. A pin on the movable member rests against the end of the long spring arm.
