ABSTRACT:
A compressor for cards stored in a drawer of magnetic material comprising a base positionable in the drawer and a compressor member mounted on the base for pivotal movement relative to the base between an extended position in which the compressor member can support the cards in a vertical position and a retracted position in which the compressor member is retracted from the cards. A spring biases the compressor member toward the extended position. A first magnet section on the base cooperates with the magnetic material of the drawer for magnetically retaining the compressor on the drawer. A second magnet section on the base retains the compressor member in the retracted position against the biasing force of the spring.
