ABSTRACT:
A cartridge loading device comprising a cartridge holder for receiving therein a cartridge; a base provided with guide grooves through which pins formed on side walls of the cartridge holder are received for guiding the cartridge holder; a loading plate supported movably to the base for causing the cartridge holder to reciprocatingly move along the guide grooves of the base between a first position where the cartridge is loaded/unloaded and a second position where a disc received in the cartridge is rotated; an eject plate supported movably to the base for unloading the cartridge received in the cartridge holder at the first position and for allowing, when the cartridge is loaded, the cartridge holder to the second position; a sub-eject plate supported movably to the base coming into contact with the loading plate; at least one first resilient member connected at one end to the loading plate and at the other end to the sub-eject plate for resiliently engaging the loading plate and the sub-eject plate with each other; at least one second elastic member for biasing the loading plate in one direction; at least one third resilient member for biasing the eject plate in a direction for discharging the cartridge; a first lock lever engaging with a lock claw formed in the loading plate to thereby lock the loading plate and restrict a movement of the loading plate; a second lock lever for locking the sub-eject lever and restricting a movement of the sub-eject lever; and a solenoid for driving the first lock lever.
