Disk apparatus

摘要

A disk apparatus is disclosed. A movable chassis assembly having a turntable and a pickup head is detachably supported on elastic members by a stationary chassis assembly with the lock mechanism of the stationary chassis assembly engaged with lock pins disposed on the movable chassis. A holder located on the movable chassis assembly for holding a disk cartridge to load or eject the disk cartridge is transported by a loader located on the stationary chassis assembly in a predetermined transport direction. Pin driving means located in the loader disengages lock pins when the lock mechanism is touched by the pin driving means at the end of the loading operation of the disk cartridge. A pair of pivoting cross links are connected at their crossings by a support pin that is engaged with a first guide slot in the stationary chassis assembly. One end of each of the pair of cross links is slidably engaged with a guide slot in the loader. The other end of each of the pair of cross links is slidably engaged with a guide slot in the stationary chassis. This arrangement eliminates variations in the load during loading and ejecting operations. A stable operation of the disk apparatus is thus assured. The disk apparatus prevents a double insertion of cartridges and an incorrect insertion, freeing the cartridge and disk apparatus from physical damage.
