Description

  The present invention relates to a disk device, and in particular, an autochanger is mounted which extracts a desired disk from a disk such as a CD, MD, or DVD stored in the apparatus and reproduces or records the disk. The present invention relates to a disk device.

  Conventionally, a disk device that reproduces data recorded on a disk using a laser beam or records data on a disk (hereinafter referred to as reproduction / recording) is known. CDs, MDs, DVDs, and the like are known as disks to be reproduced / recorded by such a disk device.

  On the other hand, in recent years, in order to reduce complicated disk replacement work in a disk device, an autochanger is mounted on the disk device, and a plurality of disks are stored in advance in a disk holding portion of the autochanger, and a desired disk is automatically loaded. A disk device for reproducing / recording has been put into practical use. An initial disc device equipped with such an autochanger is composed of a playback unit for playing a CD and a magazine for storing a plurality of CDs, like the disc playback device shown in Patent Document 1. The magazine was detachably attached to the side of the playback unit. For this reason, in the early stage of a disk device equipped with an autochanger, the disk in the magazine and the disk reproduced by the reproducing device do not overlap when viewed in plan, and the size of the disk device, particularly the projection area, is large. It was.

  As a disk apparatus that solves this problem, a disk apparatus having a reduced projection area, such as a disk reproducing apparatus disclosed in Patent Document 2, has been proposed. The proposed disc device includes a disc holding unit for storing a plurality of discs provided in the reproducing device so as to be movable up and down, and a disc reproducing / recording unit for reproducing / recording a desired disc pulled out from the disc holding unit. And a recording unit. In this proposed disc apparatus, the discs are overlapped when the disc stored in the disc holding unit and the disc being reproduced by the disc reproducing / recording unit are viewed in plan (the discs overlap on the projection surface). Thus, the disk device is made compact by reducing the projected area of the disk device.

  In general, in a disc device having a structure in which the disc in the disc holding unit and the disc being played overlap on the projection surface, the disc stored in the disc holding unit is pulled out to the playback position, or the disc after playback is loaded. A disk delivery mechanism for storing in the disk holding part is provided. During the disk pull-out or disk storage operation by the disk delivery mechanism, the disk playback / recording unit is evacuated to an empty space in the disk device so as not to interfere with the operation of the disk delivery mechanism.

  An example of a conventional configuration of a disc playback / recording unit in a disc playback apparatus equipped with such a disc autochanger will be described in detail with reference to FIGS. 1 (a), 1 (b), and 2. FIG.

The disk reproducing / recording unit 3 is provided on the frame 30F and includes a turntable 32, a clamp arm 33, a clamper 34, and an optical head 36.

  The turntable 32 is rotated by a built-in motor. Further, a clamper 34 for fixing the disk on the turntable 32 is provided at a position facing the turntable 32. The clamper 34 is rotatably attached to the distal end portion of the clamp arm 33 by a rotation shaft 33A. The clamp arm 33 has a base 33B attached to the base of the swing arm 30 so as to be rotatable. The disc 2 is placed on the turntable 32 with the clamp arm 33 open. When the clamp arm 33 is closed, the disc 2 is fixed on the turntable 33 by the clamper 34 and rotates by the rotation of the turntable 32.

  Further, a moving path 35 of the optical head 36 is formed in a portion of the frame 30F between the turntable 32 and the swing shaft 31 of the swing arm 30. The moving path 35 is provided in the radial direction of the disk mounted on the turntable 32. Therefore, when the optical head 36 moves along the moving path 35, the data recorded on the rotating disk 2 attached to the turntable 32 is read by the optical head 36, or the optical head 36 reads the disk. Data is written to 2.

That is, the locking groove 27 is formed with tapered portions 27T at both ends thereof. The tapered portion 27T is for smoothly guiding the flange portion 22 of the engaging protrusion 20 to the locking groove 27.

  FIG. 6C shows a configuration of a delivery mechanism 26B of another modification of the delivery mechanism 26 of the second embodiment described in FIGS. 5A to 5C. It is drawing of the same direction as (c). The only difference between the delivery mechanism 26B of this other modification and the delivery mechanism 26 of the second embodiment is the shape of the support member 28. That is, in the delivery mechanism 26 of the second embodiment, the side surface 28F adjacent to the locking groove 27 of the support member 28 is a flat surface, but in another modification, the side surface 28F is connected to the bottom surface 27B of the locking groove 27. The only difference is that the curved surface is curved in the opposite direction. When the side surface 28 </ b> F is a curved surface, the flange portion 22 of the engagement protrusion 20 is smoothly guided to the locking groove 27. Further, another modified example in which the locking groove 27 of another modified example shown in FIG. 6 (c) is provided with a tapered portion 27T in the same manner as the locking groove 27 of FIGS. 6 (a) and (b). Is also possible. Further, as shown by a two-dot chain line in FIGS. 6A and 6B, a similar tapered portion 24T can be provided also on the top surface 24 facing the tapered portion 27T.
