Claims

[Scope of Utility Model Registration Claim] A disk tray configured to be movable between a pull-out device pulled out of the player body and a retracted position pulled into the player body, and a rack provided on the disk tray. is configured to be rotationally driven by a motor to move the disk tray between a pulled-out position and a retracted position when engaged with the rack, and to be disengaged from the rack at the retracted position. a spring biasing mechanism that forcibly rotates the partially toothed gear in a disengagement direction when the partially toothed gear is disengaged; a lock portion provided on the partially toothed gear; and a spring biasing mechanism provided on the partially toothed gear; and a locked part that is locked by the lock part, and when the rack and the partially toothed gear are disengaged at the retracted position of the disk tray, the spring biasing mechanism By forcibly rotating the partially toothed gear in the disengagement direction, the lock portion of the partially toothed gear locks the locked portion of the disk tray, thereby locking the disk tray at the retracted position so that it cannot move. A disk player configured to.
