ABSTRACT:
An apparatus comprises first and second levers supported to be rotatable on a holder which holds a disc cartridge. The first lever has one end provided with a abutting pin which abuts the shutter to open the window of the cartridge, and other end connected to a shutter-closing spring to rotate the first lever to close the window and eject the cartridge from the holder. The second lever has one end coupled to the shutter-closing spring and other end provided with a push pin and connected to a break spring to make the push pin apply a force to the side of the cartridge. When the cartridge is inserted into the holder, the shutter-closing spring decreases the bias of the brake spring whereby decreasing the force with which the push pin pushes the side of the cartridge.
