Claims (1)

[Claims for Utility Model Registration] (1) A deck equipped with a motor that rotates a disk as a removable recording medium, a carrier supported on the deck so as to be movable in the front and back direction, and a carrier in a rear position. an eject knob that moves the carrier in the ejection direction by being operated when the carrier is pushed in; and an eject knob that operates when the eject knob is pressed to move the eject pin loosely fitted in the elongated hole at the front end of the carrier in the ejection direction It is characterized by comprising an eject lever to be pressed, and a solenoid that normally holds the eject pin in an ejection prohibited position and operates based on a control signal from a control unit to move the eject pin to an ejection permitted position. A disk protection mechanism in a disk device. (2) The control unit detects whether or not the motor is rotating, and if the motor is not rotating, outputs an ejection permission command signal to the solenoid to move the eject pin to an ejection permission position. A head arm having a head that scans over the disk is rotatably supported on the deck, and a head arm that has a head that scans over the disk is rotatably supported, and a head arm that moves the carrier when the eject lever presses the eject pin in the ejection direction. A claim characterized in that a head arm retraction mechanism is provided that interlocks with the head arm to move the head arm to a retracted position from above the disk.
(1) Disk protection mechanism in the disk device. (3) The deck is provided with an encoder that detects the position of the head arm, and the control section controls the solenoid when it is determined that the head arm is in the retracted position based on the detection result from the encoder. 3. The disk protection mechanism in a disk device according to claim 2, wherein the disk protection mechanism outputs an ejection permission command signal.
