Abstract
A counter assembly which can be used in a toner cartridge has a generally circular rotatable actuator member fixedly mounted on one end of a shaft having a screw thread on its surface, a magnet made of a molded compliant magnetic material mounted on the screw thread surface of the shaft adjacent to the actuator member. The magnet is secured against rotational movement but is permitted longitudinal movement along the screw thread surface of the shaft. The actuator member is rotated in a direction to transport the magnet along the screw thread surface of the shaft away from the actuator.
