Patent ID: 7362666

Claim:
A recording and/or playback apparatus comprising: a device body; a disk tray which is moved into, or to outside, the device body; a disk rotation driving mechanism provided on the disk tray to rotate a disk-shaped recording medium; an optical pickup to write and/or read information signals to and/or from the disk-shaped recording medium; a pickup moving mechanism to move the optical pickup between the inner and outer circumferences of the disk-shaped recording medium; and a disk tray holding mechanism to hold the disk tray inside the device body, the disk tray holding mechanism including: a forcing member to force the disk tray to outside the device body; an engagement projection provided at the device body and which engages with the disk tray to keep the disk tray engaged inside the device body; an engagement piece provided on the disk tray and which is pivoted in a direction in which the engagement projection is inserted inside the device body; a pivoting piece which gets into touch with the engagement piece to limit the pivoting range of the engagement piece, to thereby engage the engagement piece onto the engagement projection or disengage the engagement piece from the engagement projection; a plunger which is engaged with the pivoting piece and inserted into a magnetic coil to pivot the pivoting piece; and a pressing piece which is put into contact with the pivoting piece when pressed by the engagement projection and thus presses the pivoting piece in a direction in which the engagement piece is engaged onto the engagement projection, when the disk tray is inserted into the device body against the force of the forcing member, the engagement piece pressing the pressing piece, the pivoting piece thus put into contact with the pressing piece being pivoted in a direction in which the engagement piece is engaged onto the engagement projection and the engagement piece being thus engaged on the engagement projection, whereby the disk tray is held inside the device body; and when the plunger pivots the pivoting piece, the engagement piece being forced in a direction in which it is disengaged from the engagement projection, whereby the disk tray is ejected to outside the device body under the force of the forcing member.
