Abstract

PURPOSE:To record and reproduce signals while containing a disc in a containing case with a simple device, by providing an aligning member and a plate spring pressing the aligning member for the disc center. CONSTITUTION:At storage, the aligning member 3 is pressed downward via a pressing pin 5 with the plate spring 7, a ring shaped stand 14 and the member 3 are sticked closely to be air-tight from the outside. In such construction, at recording and reproduction and loading, first a turntable 30 passes through a hole 16 into the containing case to press the member 3 upward. Then, the member 3 is pressed downward with the spring 7 and upward with the table 30, the member 3 contacts with the table 30 closely, allowing to attain accurate alignment by means of tapers provided for them. Further, the tables 30 goes upward, the member 3 and the stand 14 are separated, the disc 1 is positioned on the center of a space 13, allowing to attain recording and reproduction. Since the table 30 and the member 3 are contacted closely in this case, the accurate transmission of rotation is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a case for accommodating an optical disk device rt for recording and reproducing high-density information.

In general, high-density recording media have a problem in that TjIi dust, fingerprints, etc. deposited on the surface of the media cause disturbances in the information. In order to prevent this, the conventional method of storing the product in a storage case has been taken. However, when recording and reproducing the disc while it is in the storage case, the disadvantage is that the Ia barrel that aligns the disc and cranks the disc must be attached to the shaft, making the device complicated.

In the present invention, the alignment member is attached to the center of the disk, and a leaf spring that presses the alignment member is attached inside the storage case, thereby solving the above drawbacks and allowing the disk to be kept in the storage case with a simple device. To provide a disc storage case that allows recording and playback.

According to the invention, the above object is achieved by
In a storage case that has an airtight disk and is made up of an upper plate, a lower plate, etc., there is an alignment member in the center of the disk and an alignment member inside the storage case. This is achieved by having a similar spring that suppresses r.

Next, a practical example of the present invention will be described with reference to drawings ti.

As shown in Figures 1, 2, and 3, the disk 1 has a flat shape with a diameter of about 300 mm and a thickness of 1.5 mm.
So, the diameter is 290 amzh, the diameter is 190 jklKf
Therefore, the information signal 2 is formed in a spiral shape or preferably in a plurality of circumferential shapes. In the center of disk 1 is disk 1.
Aligning member 31-'N is connected to the turntable for rotating and aligned.〇On the other hand, the storage case 10μ
It consists of an upper plate 11, a lower plate 12, etc., and these upper plates 11. The lower plate 12 is made of injection-produced cedar using a 7° lath nut material in front of the sterol material.In addition, the same effect can be obtained by using other gelastic materials such as acrylic resin, scissor material, etc. 60 This top plate 1
Between 1 and bottom @ 12 is the space 13 for storage.
In addition, the center hole 4 of the alignment member 3 is formed with a
The bearing 6, the push pin 5, and the retaining ring 8 are connected to the south, and the push pin 5rlc is press-fitted into the bearing 6. Disk 1 is placed on the lower plate 12 when stored! A ring-shaped stand 14 is provided to prevent the information from being destroyed.

Furthermore, a playback hole 18 is formed at the top and bottom &11.12 through which a pickup for playing back the information signal 2 of the disc 1 is passed, and a lid 19 is attached to the playback hole 18 by means of a hinge. installed.

Note that the upper and lower plates 11 and 12 are held together by screws 20.

4 and 5 are enlarged sectional views of the vicinity of the center hole 16 of this embodiment. During storage, the leaf spring 7 is
As a result, the centering member 3 is pressed downward via the push pin 5, and the ring-shaped stand 14 and the centering member 3 are closely layered to form a Confucian structure that is airtight from the outside. When installed during recording and reproduction, the turntable 30 first passes through the hole 16 and enters the storage case and pushes the centering member 3 upward.Then, the centering member 3 is pushed downward by the leaf spring 7 and upward by the turntable 30. The alignment member 3 and the turntable 30 are closely layered, and the tapers provided on each allow accurate alignment. Further, the turntable is raised upward, and the alignment section 3 and stand 14 are removed, and the disc 1 is located at the center of the space between the walls 13, making it possible to record and reproduce as shown in FIG. At this time, since the turntable 30 and the centering portion 3 are in close contact with each other, accurate rotation transmission is performed. When removing 7iIiF, the above fabrication is performed in reverse.

As explained above, in the present invention, the disc is stored in the storage case, and by providing a temporary spring or the like to press the alignment capital V and the alignment member in the middle heat section of the t1 disc, the disc can be kept stored inside the storage case. This has the effect of being able to record and reproduce discs using a simple device.
