DISK APPARATUS

摘要

A disk apparatus comprising a tray (102) for mounting a disk thereon, a lock arm (117) for locking the tray (102) to a main body chassis (100) and releasing this locking, a coil (111) for operating the lock arm (117) by an electromagnetic force, a coil holder (112) for holding the coil (111) and transmitting the electromagnetic force to the lock arm (117), a magnet (116) for applying a magnetic flux necessary for the operation, a rail (103) for holding the tray (102) to the main body chassis (100) and guiding an accommodation/ejection operation, a push block (104) for pushing out the tray (102), a push spring (105) for operating the push block (104), an eject button (106) pushed down when the user wants to eject the tray (102), a detection switch (107) for detecting the push-down of the eject button (106), and a controller (108) for applying a voltage to the coil (111) upon receiving the detection information.
