Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk device, and particularly to a disk device that can record and reproduce data whether the disk is alone or stored in a case.

[Conventional technology]

When recording and playing discs with conventional disc devices,
There are cases in which the disk is used alone, and cases in which it is housed in a case as shown in FIG. 2 in order to protect the disk and improve its handling.

Here, case 1 will be explained using FIG. 9. 9th
The figures are configuration diagrams showing the configuration on the case, where (a) is an external view and (b) is a sectional view taken along the line A-A. 2 is the main body;
A disk (not shown) is stored. Reference numeral 3 denotes an opening into which a turntable (not shown) for rotating a disk during recording and reproduction is inserted, and recording and reproduction are performed through this opening 03 by an optical head (not shown). 4a, 4t
) is a positioning hole, which is used when positioning the case within the disk device. Reference numeral 5 denotes an insertion slot, which is used to hold the case inside the disk device.

The shutter 6 is biased by an internal spring (not shown) to close the opening. Reference numeral 7 denotes an opening slot, which is provided so that a shutter opening/closing mechanism (not shown) and the shutter 6 can be engaged with each other. Reference numeral 8 denotes a cover, which is opened and closed when replacing a disk (not shown) stored in the main body 2. Reference numeral 9 denotes a clamper, which is used to press a disk (not shown) against a turntable (not shown) during recording/reproduction. 610 is a magnetic material, which is attached to the clamper 9 and is used to press a disk (not shown) against a turntable (not shown). ) is used to generate a disk pressing force by being attracted by a magnet (not shown) attached to the disk. The clamper 9 is rotatably held by the cover 8.

By the way, during recording and reproduction, it is necessary to mount the disc on a turntable and use a clamper.

In a disk device that uses a single disk, the operator places the disk on a turntable either directly or using a disk holder, etc., and then moves a clamper to press the disk against the turntable to record. - It was now possible to play. An example of this type of device is disclosed in Japanese Patent Application Laid-Open No. 58-68267.

In a disk device that is used with a disk housed in a case, the case is inserted into a case holder. At this time, the shutter is fully opened by the shutter opening/closing mechanism, and then the case is moved to a predetermined position. As a result, the disk is placed on the turntable, and the clamper 9 presses the disk by the attraction force acting between the magnetic material 10 and the magnet fixed to the turntable.
It was now ready for recording and playback. An example of this type of device is JP-A-60-45970.

[Problem to be solved by the invention]

In the case of the former disk device, no consideration was given to using a disk stored in a case, and it was necessary to take out the disk to use it. Furthermore, in the latter case, no consideration was given to the use of a single disc, and the disc had to be stored in a case before use.

In this way, moving the disk in and out of the case while moving the disk device is not easy to operate, and there is a risk of damaging the disk.

SUMMARY OF THE INVENTION An object of the present invention is to provide a disc device that can be loaded, recorded, and played back whether the disc is alone or stored in a case.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a case holder with a notch to prevent interference with the disc when mounting the disc on the turntable, and a shutter The amount of protrusion of the holding bottle of the opening/closing mechanism into the case holder is made smaller than the distance between the disc attached to the turntable and the case holder.

In order to accommodate a disk device using a case in which the first clamper is built into the case, a second clamper and a clamper holding mechanism for rotatably and movably holding the clamper are provided. When the case is not inserted, the second clamper is positioned above and facing the turntable.

In addition, a clamper holding mechanism was provided on the case holder.

Furthermore, it serves both as a shutter opening/closing mechanism and a clamper holding mechanism.

[Effect]

When using the disc alone, place the disc on the turntable and perform the mounting operation. As a result, even if the case holder moves, since the case holder is provided with a notch, the disc and the case holder will not interfere. Since the amount by which the shutter engaging portion of the shutter opening/closing mechanism projects into the case holder is smaller than the distance between the disc mounted on the turntable and the case holder, the engaging portion and the disc do not come into contact with each other. If there is a second clamper, the second clamper is located above and opposite the turntable and presses the disk against the turntable. Therefore, the disc becomes ready for recording and reproduction.

When removing the disc, perform an ejection operation. As a result, the disc is placed on the turntable.

You can remove the disc here.

If a second clamper is present, the ejecting action causes the second clamper to move away from the disc, allowing the disc to be removed.

When using a disc stored in a case, the shutter is fully opened by the shutter opening/closing mechanism when the case is inserted into the case holder. The second clamper is movable, so
Since it moves in conjunction with the insertion of the case, it does not interfere with the insertion of the case. When the shutter is fully opened and the mounting operation is performed, the case is positioned at a predetermined position. At this time, the disc inside the case is attached to the turntable. If the case has a built-in first clamper, the first clamper presses the disc against the turntable. Therefore,
The disc becomes ready for recording and playback.

When removing the case, a discharge operation is performed. This will result in the state when the case is inserted. At this point, the case can be removed or it can be automatically ejected. When taking out the case, the first clamper moves in conjunction with the case and returns to a position above and facing the turntable.

As described above, the disc can be used whether it is alone or stored in a case.
