Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a disc record reproducing apparatus suitable for an optical DAD (7-'notal audio disc) system.

[Technical background of the invention and its problems]

Recently, in the field of audio equipment, high fidelity U
(A) A digital recording and playback method using PCM (Pulse Coat Mosolation) technology has emerged and is becoming popular. This is because it has been established in principle that it is far superior to conventional analog systems, regardless of the characteristics of the medium.In this case, as a recording medium, ,disk(
The DAD system is called a DAD system, and even if the playback method and raw method are adopted, the playback device that embodies this system can be used in various ways that are not found in conventional ones. It is required that the device satisfies the advanced functions and performance of the device.

For example, among the optical playback methods, optical disc playback using the CD (contact printing) method) is used in raw lacquer (J: PCM) for one transparent body and one fat disc. Kingyosukuri k-1k 21+ that forms pits (irregularities with different reflectances) corresponding to the data

The purpose is to satisfy the requirements of the valley scale.

By the way, one possible example of the additional functions required in this way is the appearance of optical discs of different diameters (for example, small diameters) with different m-report recording capacities compared to the 12 cm diameter discs mentioned above. It will be done.

(and) In this way, a device that targets multiple discs of different diameters simply sets the discs of different diameters at 5.
It is not just a matter of escaping the 't'; it must be able to meet the various demands of an all-powerful optical disc record playback device in relation to the disc drive unit and loading mechanism. Must be 4'L.

[Purpose of the invention]

[Practice of the invention]

Hereinafter, one embodiment of this support 1↓1j will be described in detail with reference to the drawings. In other words, the first quotient is the DAD (hereinafter referred to as disk and "jj") of the optical V disk record playback device.
L: This shows the external appearance of the loading section, and 12 is a disk sporage provided at the front of the cavity 11.

This disk porgoo 12 is rotatably loaded δ in the direction of the arrow A in conjunction with the operation of the inoect operator 13, which is a so-called kangaru-pocket type. By inserting the Q discs (the size of each of which is not shown in the first E' ladle) approximately vertically, the disk size (r
It is cut so as to be selectively regulated to the JJ position.

2 shows the details of the disk holder 12, which accommodates a disk (not shown in FIG. 2) in a substantially vertical manner. That is, the disc holder 12 is provided with a hollow disc storage section 17 inside the holder cover 16 thereof.

The surface forming the bottom surface of the disk storage portion 17 (opposed to the disk surface) has an upper and a lower g at one end thereof.
First and second elongated holes 113 and 19 each curved toward the center are formed in fs, and third and fortieth elongated holes 2θ each curved toward the center at the upper and lower portions of the other end;
2 is formed.

Further, inside the disc storage portion 17, a rotary shaft and a 20th rotation shaft 22, 23 are provided in the first and second elongated holes 18.

: is not shown) and corresponds to the large-diameter disk 15, and is disposed so as to be movable between the first and second positions.

3- shows the detection section 26 of the first regulation member 24, and the support section 28 of the first regulation member 24 and the detection section 27 and support section 29 of the second regulation member 25 are substantially the same. , so its explanation will be omitted here. That is, the first regulating member 24 has a bottomed cylindrical guide part 30 formed on the lower surface of the detection part 26, and a sedge ring member 3 is interposed in the guide part 30, so that the first regulating member 24 has a bottomed cylindrical guide part 30. A ball member 32 is provided.

On the other hand, the first elongated hole 1 is provided in the guide storage portion lz.
8, the first and 20th locking loops are spaced apart at a predetermined interval 3.9
, 34 are formed corresponding to the first and second positions. These first and second locking grooves 33 and 34 are continuous with each other, and the ball member 3 of the guide portion 30
2 is movably guided and locked in the locking grooves 33 and 34.

That is, as shown in FIG. 4, the disc boulder 1
In order to store the large and small diameter disks 15.35 in the disk storage section 2, the storage is completed by inserting the disks in the open state into the disk storage section 17 in the direction of arrow C. After this, if a large-diameter block 15 is inserted, the lth

Then, the 7" disk holder 12 loads the disk 35 with a diameter of /" in place of the large diameter disk 75 in the disk storage portion 17, and the large diameter disk 16 is moved in the direction of the arrow. When the disc 15 is taken out, the peripheral edge on the base side of the large-diameter disk 15 presses the detection parts 26 and 27 of the first and second regulating members 24 and 25, respectively, in the counterclockwise and Rotate clockwise. As a result, the large-diameter guide shaft 15 allows each of the detection sections 26 and 27 of the first and second regulating members 24 and 25 to rotate most counterclockwise and clockwise in the figure, respectively, due to its maximum diameter.

Here, the ball members 32 of the first and second regulating members 24 and 25, respectively, of the supporting parts 28 and 29 and the detecting parts 26 and 27 are locked in the first locking groove 33 as described above. It is made to be stable at the first position (position i1 indicated by the dashed line in the figure). In this way, by removing the large-diameter r disk 15trtt from the disk storage portion 17 of the disk holder 12 (t4), the above-mentioned first and second rules of 4.2 can be achieved.

In conjunction with the attachment and detachment of the large diameter disk 15, the first and second positions are taken according to the disk size. In order to solve this problem, the above-mentioned optical disc record playback device can improve its operability by eliminating the complicated operations depending on the disc size, and it is possible to prevent erroneous operation. This can be prevented.

The present invention is not limited to rotational loading as described in the above embodiments, but is equally effective when applied to horizontal loading in which a disc holder is provided in and out of a cavity. Therefore, it goes without saying that this invention can be modified without departing from the gist of the invention.

〔Effect of the invention〕

As described above, it is an object of the present invention to provide an extremely good optical disc record playback device which has a simple configuration and which is capable of reliably guiding optical discs of different diameters to respective drive positions. I can do it.
