The tray 2 is pressed against the cartridge placement side by the biasing force of the biasing member 33 acting on the sliding pin 37.
  • the contact member 32 is rotatable with respect to the arm member 31, but may be fixed. Further, a force in which an urging force is applied to the arm member 31 by the urging member 33 by the urging member 33.
  • the arm member 31 itself has elasticity, and the urging force may be generated like the urging force to the tray 2.
  • the disk apparatus is the disk apparatus 1 that reproduces information recorded on the disk D1 housed in the cartridge 5 and records information on the disk D1.
  • Cartridge placement position force for placing cartridge 5 Tray 2 moves to the disc playback position where playback and recording of the disc D1 stored in this placed cartridge 5 is performed.
  • the disk device according to the present invention is useful for a disk housed in a cartridge and a disk device that can be used for misalignment of the disk, which is likely to be housed in the cartridge. It is suitable for improving the stability of tray operation.

Abstract

L'invention concerne une unité de disque comprenant un plateau (2) et un dispositif de pression (3). Le plateau se déplace entre une position de placement de cartouche dans laquelle une cartouche (5) est placée sur le plateau et une position de lecture de disque dans laquelle une lecture à partir d'un disque (D1) reçu dans la cartouche (5) sur le plateau et un enregistrement sur ce disque sont réalisés. Le dispositif de pression (3) comprend un bras (31) dont une extrémité est supportée de façon à pouvoir tourner vers le côté de placement de cartouche, un élément de contact (32) fixé à l'autre extrémité du bras (31) et mis en contact avec une nervure de pression (23) formée sur le plateau (2), et un élément de sollicitation (33) sollicitant le bras (31) vers le plateau (2). L'élément de contact (32) est en contact avec une partie (23b) de la nervure de pression (23) pendant le déplacement du plateau (2), lequel subit alors une pression à partir du côté de placement de cartouche. En outre, l'élément de contact (32) est en contact avec la cartouche (5) lorsque le plateau se trouve en position de lecture de disque, la cartouche (5) subissant alors une pression à partir du côté de placement de cartouche. Cela permet de supprimer les rayures sur la cartouche et d'améliorer la stabilité de fonctionnement du plateau.
