摘要:
A disk reproducing apparatus with a plurality of disks arrayed and held therein selects a desired disk for reproduction from the arrayed disks. The disk reproducing apparatus includes an insertion slot which defines an insertion executable position, a disk holding device including a plurality of disks inserted through the insertion slot by arraying the disks in a direction perpendicular to main surfaces of the disks, the disk holding device being movable in a direction of arrangement of the disks, a disk reproducing device having upper and lower surfaces opposing in the direction of arrangement of the disks, the disk reproducing device being movable in the direction of arrangement of the disks, and reproducing a disk to be reproduced at a reproduction executable position at which the upper surface faces the disk to be reproduced. When a disk is to be inserted, the disc reproducing device is placed at a position where the lower surface is positioned near to the insertion executable position in the direction of arrangement of the disks. When a disk is to be reproduced, the disk reproducing device is placed at a position where the distance of the upper surface from the insertion executable position in the direction of arrangement of the disks is smaller than its distance at the time of insertion of a disk. Thereby the reduction in size of the apparatus as a whole and a smooth execution of the reproduction operation are attained.
摘要:
In a disk reproducing apparatus a plurality of disks each carrying information recorded therein are inserted through an insertion opening and arrayed and held in a predetermined direction and a desired disk is selected for reproduction from the plurality of disks arrayed and held therein. The disk reproducing apparatus comprises a disk holding device including a plurality of trays arranged for holding thereon the plurality of disk respectively, a disk carrying device which carries the disk between the insertion opening and the tray, and a disk reproducing device which is carried to be positioned outside an area where a disk held by the disk reproducing device exists when the disk is not being reproduced and positioned that at least a portion is inside the area where the disk exists, when the disk is being reproduced. The disk carrying device and the disk reproducing device are juxtaposed in a direction in which disks are arrayed when the disk is not being reproduced. With this feature, minimization of the entire size of the apparatus and simplification of the construction are realized.

A disk reproducing apparatus with a plurality of disks arrayed and held therein for selecting a desired disk from the arrayed disks and reproducing the disk. The disk reproducing apparatus comprises a disk holding device including therein a plurality of trays holding thereon a plurality of disks arrayed in a direction perpendicular to a main surface of the disk, a disk reproducing device positioned at a non-reproduction position outside the disk holding position where disks held by the disk holding means are located when the disk is not reproduced and positioned at a reproducing position where at least a portion thereof overlaps the disk holding position when the disk is reproduced, a reproducing device carrying mechanism for transferring the disk reproducing device between the non-reproducing position and the reproducing position, a disk selecting device for positioning a disk to be reproduced at a specified position to allow the disk reproducing device to move into the reproducing position when reproducing the disk and for moving aside other disks in the direction of the array of disks, and a disk retrieving and transferring device for taking out and transferring the disk to the reproducing position. When reproducing a disk, an operation for transferring the disk reproducing device from the non-reproducing position to the reproducing position and an operation for transferring the disk from the disk holding position to the reproducing position are executed simultaneously.
