Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing device, and more specifically, to an information processing device that rotates and moves a disk-shaped recording medium, records information on the recording medium, or records information recorded on the recording medium. The present invention relates to an information processing device that reproduces .

2. Description of the Related Art In recent years, optical information recording and reproducing devices such as optical discs have been attracting attention as recording and reproducing devices for image information, audio information, and the like. Recording or reproduction in such a device is performed as follows. That is, a disk-shaped recording medium (disk) is rotated, a light beam modulated according to the information is irradiated onto the disk, and the shape or magnetization direction of the medium is changed to record information. A light beam is irradiated onto a recorded medium, and changes in the amount of reflected light are detected by a light receiving element and reproduced as information.

The reasons why the above device is attracting attention are: 1. High-density information can be recorded on a small disk.

2. Access time is short.

etc.

However, in order to perform high-speed and high-density recording or reproduction, the rotation of the disk must be increased from 500 to 1800 r, p, m.
.

At this rotation speed, a considerable centrifugal force acts on the disk. Glass, plastic, etc. are generally used as the base material of the disk, but when the disk is rotated at high speed as described above, there is a possibility that the disk will be damaged during rotation due to centrifugal force.

Therefore, in conventional information processing apparatuses, particularly optical information processing apparatuses, the mounting position of the disk is lower than the side plate of the main body, and the user is protected from the fragments of the disk when the disk is damaged by the robust front side plate of the main body.

However, in the conventional device as described above, the disk is located below the side plate of the main body, that is, deep inside the device.
When attaching or detaching the disc, you had to insert your hand from above, making it difficult to operate. In order to eliminate this drawback, if the disk is placed above the side plate of the main body, it is necessary to provide a sturdy cover for protecting the device in case the disk is damaged as described above. As a result, the length of the upper cover 1 increases, and force is required to open and close it. Further, there arise problems such as an increase in the cost of the hinge portion and the like.

An object of the present invention is to provide an information processing device d which overcomes the above-mentioned drawbacks, has good operability, and is not safe.

The present invention achieves the above object by rotating a disc-shaped recording medium and recording information on the recording medium, or by using the recording medium.

Embodiments of the present invention will be specifically described below with reference to the drawings.

Figures 1) and (B) are cross-sectional views showing the first embodiment of the present invention, in which (A) shows the state when the top cover is open and the disc is attached or removed, and (B) shows the state when the disc is in operation, that is, during recording or playback. The situation is shown below. In order to simplify the explanation, the recording or reproducing head is not shown here.

In FIG. 1(A), a turntable 2. K is provided with an IJ 7 g-shaped member 6 at the end 5, and a side plate 4 of the main body is installed while keeping the ice rim 5 horizontal.
It is held in the high attachment/detachment position. The diameter of the spindle 7 on the rotating shaft near the top surface of the turntable 2 is determined to fit into the hole in the center of the disk, and its tip is tapered. With the above-mentioned members, when the lid 8 of the device is opened, the disk 5 is roughly positioned by the hole in the center of the disk 5 and the tip of the spindle 7, which is thinner than the diameter of this hole, and be pushed to a higher position. Therefore, with the lid 8 open, the disk can be easily attached and detached.

) in FIG. 1 shows the operating position ta of the disk in this embodiment.
shows. ) in Fig. 1, when the lid 8 is closed, the disc presser 9 attached to the lid presses down the disc 5 against the coil spring 4, and the hole in the disc 5 is tapered and fitted into the lower end of the spindle 7. disc 5
is positioned.

The disc holder 9 has a rubber 10 attached to its tip, and is adapted to firmly sandwich the disc 5 between it and the turntable 2. Here, the rubber 10 is also effective in that it does not damage the disk surface. This disk presser 9 has a groove in its upper part, and a member 1 attached to the lid.
It is supported by 1. The upper end wall of the disc holder 9 is spherical, and when the lid 8 is closed, this also contacts the tapered surface of the thrust bearing 12 attached to the lid 8, and when the disc rotates, the disc holder 9 also rotates together with the disc 5. do.

As mentioned above, the disc operating position in this embodiment is at the main body side plate 6.
Even if the disc breaks during high-speed rotation, the sturdy side panels protect the user.

FIG. 2 is a perspective view of a second embodiment according to the invention.

For the sake of explanation, the disk is not shown here. In FIG. 2, pulleys 13, 14, and 15 with crank-shaped shafts are attached to the side plate 26 of the main body, and Boo! Change the direction of the wire 18 using J16, 17, and connect the pulleys 13, 1 to each
The wire 18 is wound around 1.15. One end of the wire 18 is fixed to the main body via a spring 19, and the other end is fixed to the lid 28 via a pulley 20, which is also attached to a side plate 26 of the main body. When the lid 28 is opened, the wire 18 is pushed against the spring 19.
By pulling and turning pulleys 12, 13° 14,
The end of the crankshaft rotates and moves upward. Further, the recording/reproducing head 31 is movable in the radial direction of the disk along a guide 62 by a motor (not shown).

FIG. 3(A), (13) shows a sectional view of the second embodiment.

As shown in Figure 6), when the lid 28 is opened, the pulley 1
The disk 25 is pushed up by the crank-shaped shaft attached to 3 and 14, and is held at the attachment/detachment position by the side plate of the main body. Here, reference numeral 30 (not shown in Fig. 2) is a stopper, and if it is installed so that the crank-shaped shaft is stopped at a position slightly rotated from the highest point, the crank-shaped shaft can be kept at the attachment/detachment position even when a disk is mounted. It can be stabilized. At this time, the hinge (not shown) of the lid 28 resists the tension 1 of the spring 19 and moves the lid to the open position 11.
1%-f't, 29, Nepa 1m, □, say.

FIG. 6 (13) shows the case when the lid is closed. As the lid 28 is lowered, the wire 18 is pulled by the spring 19 in FIG. moves downward.

This causes the disk 25 to move along the spindle 27.
It is lowered to the operating position on the upper surface of the turntable 22 and is held between the turntable 22 and the disc holder 29. Further, it is rotated at a position lower than the main body side plate 26, and recording or reproduction is performed by a head (not shown).

In this manner, the present implementation provides an information processing device that is easy to operate and has high safety.

In the above embodiments, it was possible to open and close the lid of the device, but
Regardless of the condition of the lid or cover, there is no difference in electric power.

As described above, the present invention facilitates attachment and detachment of the conventional information processing apparatus by raising the attachment and detachment position.

2. By setting the operating position to the lower position 1a of the device,
Increases safety in the event of disk damage.

3. By lowering the operating position, an inexpensive and lightweight lid or cover can be used.

It has the following effects.
