Disk apparatus

A disk apparatus comprising a tray for mounting a cartridge that houses a disk having an information layer and has an aperture for exposing the information layer and a shutter for opening/closing the aperture, a conveyor for conveying the tray, an opener that engages with the shutter so as to open/close the shutter in a substantially cross direction with respect to the conveyance direction of the conveyor, a plurality of guiding members arranged independently, and an engaging member formed in the opener and engaging with the guiding members;

• wherein
• the plural guiding members are arranged so that, as the tray is conveyed, at least one of the engaging members moves following the guiding members while the opener moves in a substantially cross direction with respect to the conveyance direction;
• and
• as the conveyance proceeds, at least one of the engaging members engaging with the guiding members is disengaged and engages with a separate guiding member so as to continue its movement following the separate guiding member, so that the opener continues to move in a substantially cross direction with respect to the conveyance direction.

A disk apparatus comprising a tray for mounting a hole-formed cartridge that houses a disk having an information layer, a motor for rotating the disk, and a base having a first projection and the motor mounted thereon;

• the tray has a second projection for engaging in the hole of the cartridge and a hole for engaging with the first projection of the base;
• at a loading position for loading the disk on the motor, the first projection of the base engages in the hole of the tray so that the tray is positioned on the base;
• and
• when the cartridge is mounted on the tray, the second projection of the tray engages in the hole of the cartridge so that the cartridge is positioned on the tray.

A disk apparatus comprising a tray for mounting a disk having an information layer;

• a conveyor for conveying the tray;
• a base on which a motor for rotating the disk is mounted;
• a part-to-be-engaged which the tray in conveyance engages with and slides on;
• a box for containing the tray, the conveyor and the base;
• and a pressing member for pressing the tray onto the base;
• the base being attached to the box via a damper, and at a position for loading the disk on the motor, the tray is pressed to the base by the pressing member and separated from the part-to-be-engaged.

A disk apparatus comprising a tray for mounting plural kinds of disks having information layers and different from each other in outer diameter, and a position controller for controlling the positions of the disks;

• the position controller comprises a first wall face for controlling the position of a first disk in a main face direction, a rotation axis arranged at a position indented from the main face of the tray and extends in the substantial radial direction of the first disk mounted on the tray, a plurality of elements connected via the rotation axis, and a biasing member for applying a force to the plural elements in a direction for floating the first disk from the tray main face;
• the tray comprises a second wall face for controlling the position of a second disk in the main face direction, where the second disk is smaller than the first disk in the outer diameter;
• and
• the position controller extends toward the center of the second disk mounted on the tray main face with respect to the second wall face, and a part of the position controller and a part of the main face of the second disk overlap each other in a state in which the second disk is in contact with the second wall face.
