TECHNICAL FIELD OF THE INVENTION
The present invention relates to a disk device that pulls out a disk from a disk holder to perform recording and reproduction, and a disk holder used in the disk device, and more particularly, to a disk holder and a disk device with an improved insertion portion for the disk.
[0002]
[Prior art]
2. Description of the Related Art In recent years, various types of disk devices for recording and reproducing a recording medium such as a disk have become widespread. Are known. In the tray type, a disc is placed on a disc tray protruding from the front of the disc device, and the disc tray is returned into the device, whereby the disc is transported to the recording / reproducing unit. In the holder type, a disk holder holding a disk from its surroundings is loaded in a disk device in advance, the disk is pulled out from the disk holder by a mechanism inside the disk device, and the disk is transported to a recording / reproducing unit. is there.
[0003]
The disk holder used for the holder type has an advantage that it can be made thinner than the disk tray used for the tray type, so that the size of the disk device can be reduced and an auto changer type in which a plurality of disks are loaded. Suitable for a disk drive. This autochanger type disk device is convenient because it is not necessary for the user to insert and remove disks one by one in order to exchange disks for recording and reproduction.
[0004]
A commonly used disk device is a disk device provided with a disk magazine capable of storing a plurality of disk holders in a multilayer structure. This disk device includes a disk magazine, a mounting unit to which the disk magazine can be attached and detached, a transport unit for transporting a disk holder, a recording / reproducing unit including a pickup, a turntable, a clamper, and the like. The disk magazine mounted on the mounting portion is box-shaped, and a plurality of grooves are formed in the left and right inner side surfaces in the horizontal direction. Since both ends of the disk holders for individually storing the disks are inserted into these grooves, a large number of disk holders are stacked in the disk magazine. The individual disk holders stacked and housed in this manner have an insertion portion on one end side of the disk holder in which a disk can be inserted and ejected in a direction (horizontal direction) parallel to the main surface thereof, and can be inserted into a disk magazine. The disc is provided so as to be able to be taken in and out in the same direction as the direction of insertion and ejection of the disc.
[0005]
In the above-described disk device, when recording / reproducing a disk, first, a disk magazine is mounted on a mounting portion. Then, the disk holder holding the disk for which recording or reproduction has been instructed is pulled out to the recording / reproducing unit side by the transport unit, and the disk is clamped by the turntable and the clamper. Thereafter, only the disc holder is returned into the disc magazine by the transport unit while ejecting the disc, and recording and reproduction of the disc are performed by the pickup.
[0006]
When recording / reproducing another disc or removing the disc magazine from the loading section, move the empty disc holder horizontally to the recording / playback section again, and insert the disc held by the turntable into the insertion section. To be stored. Then, after the disk is released, the disk holder containing the disk is returned to the disk magazine, and recording and reproduction of another disk is performed in the same procedure as described above, or the disk magazine is removed. .
[0007]
[Problems to be solved by the invention]
However, the above disk device has the following points to be improved. That is, as described above, when returning the disk held on the turntable to the disk magazine, the disk holder moves in the horizontal direction, and the disk is stored in the disk holder from the insertion portion. This disk holder is inserted into the grooves on the left and right inner side surfaces of the disk magazine.However, in consideration of making the disk magazine thinner and preventing the disk from vibrating in the disk holder, the grooves need to be formed narrowly. The positional accuracy required for inserting the disc into the holder is high. However, when the disc is not accurately held on the turntable or when the disc itself is deformed, the height difference between the side surface of the disc and the insertion portion of the disc holder occurs. When such a deviation occurs, there is a possibility that the end of the disk hits the end on the insertion portion side of the disk holder, or the disk cannot be stored in the disk holder.
[0008]
To cope with this, if the frontage of the insertion portion of the disc holder is widened, the error due to the above-mentioned misalignment can be absorbed, and the possibility of causing a problem can be reduced. However, when the frontage of the insertion portion is widened in this way, the thickness of each disk holder in the height direction is increased. Then, it is necessary to increase the height of the disk holder for accommodating a large number of disk holders in a stack in the height direction, resulting in an increase in the size of the entire disk device.
[0009]
The present invention has been proposed in order to solve the above-described problems of the prior art, and its object is to securely insert a disk at a reproduction or recording position into a disk holder without increasing the size of the apparatus. The object is to provide a disk device that can be returned.
[0010]
Another object of the present invention is to provide a disc holder that can reliably insert a disc and does not increase the size of a disc device.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the invention according to claim 1 is directed to an insertion portion capable of inserting and removing a disk in a direction parallel to a main surface thereof.A disc holder housed so as to be able to be taken in and out of the disc magazine. A guide member urged in an opening direction by an elastic member when pulled out of the gin is provided, and the guide member is, when housed in the disk magazine, another disk holder or another disk holder in the disk magazine. A contact portion that contacts the inside of the disc magazine and narrows the insertion portion..
[0012]
The invention according to claim 2 is2. The disk holder according to claim 1, wherein the elastic member constitutes all or a part of the guide member..
[0013]
According to the first and second aspects of the present invention,When returning the disc held by the reproducing means or the recording means into the magazine, when the disc holder is pulled out of the disc magazine, the guide member opens, and the frontage of the insertion portion widens. Therefore, even when the height difference between the end portion of the disc and the insertion portion occurs, the error due to the displacement can be absorbed by the spread of the insertion portion, and the disc can be inserted reliably. Further, when the disk holder is stored in the disk magazine, the guide member closes, and the frontage of the insertion portion is narrowed. Accordingly, the individual disk holders do not become thicker, and it is not necessary to increase the size of the disk holders accommodating these disk holders. As a result, it is possible to prevent the entire disk device from being enlarged..
[0014]
Further, when the disc holder is accommodated in the disc magazine, the insertion portion is narrowed by the contact portion, so that the contact portion prevents the disc from jumping out of the disc holder. Further, since the guide member is biased by the elastic member, the opening and closing of the guide member is automatically performed by the elastic force..
[0015]
The invention according to claim 3 is3. A disk device comprising: the disk holder according to claim 1; and a reproducing unit or a recording unit that reproduces or records information in the disk pulled out from the disk holder. The disc holder is provided so as to be positioned at a position where an end of the disc being reproduced or recorded by means and an end of the disc holder on the insertion portion side overlap with each other..
[0016]
According to the third aspect of the present invention,Since the end of the disc being reproduced or recorded overlaps with the end of the disc holder, the disc is not completely separated from the insertion portion. Therefore, even when the height difference between the disk end and the insertion portion occurs, the end of the disk contacts the end on the insertion portion side and is regulated, and the disk is prevented from coming off from the insertion portion. When returning to the disc holder, it can be inserted securely.
[0017]
The invention according to claim 4.The disk device according to claim 3, wherein an end portion of said disk holder overlapping with an end portion of said disk is provided with a thin guide piece..
[0018]
In the invention according to claim 4 described above,Since the end of the disc holder overlapping the end of the disc is a thin guide piece, the frontage of the insertion portion is widened, and the end of the disc being reproduced or recorded is less likely to come into contact with the end of the disc holder..
[0019]
