Abstract
A device for actuating a shutter of a disc cartridge along with insertion of the disk cartridge into a holder of a recording and/or reproducing apparatus is disclosed. The device includes an engaging pin mounted on a lever member and adapted to be in engagement with one end of the shutter during the travel of the cartridge from a half-loaded position to a full-loaded position. The engaging pin extends downwardly through an oblique-inwardly engaging slot and protrudes into a cartridge accommodating space within the holder. A very small force is needed to smoothly actuate the shutter because a guide pin secured to the cassette or disc cartridge holder will act as an axis of rotation for the lever member 14 by vitrue of a slot provided in the other end of the lever member from the engaging pin. The guide pin is rotatably and linearly displaced with regard to the slot in the lever member. In a second embodiment of the invention, a second pin is placed in the lever member in place of the slot and a platform having a slot in the cartridge inserting direction engages said second pin.
