JPS6220168A - Disc exchanger - Google Patents

Abstract

PURPOSE:To improve operability of the titled exchanger by providing a means to turn over a disc to a carrier that receives an optional disc. CONSTITUTION:Recording or reproducing is executed in or from an optical disc clamped by both guide rails 33 and 38 through a disc motor 5 and an optical head 6. Whether side A or side B of the disc is to be recorded in or reproduced from is determined by a command from a controller. In case the disc is clamped inversely, an inversion signal for the disc 1 is supplied to a drive motor 36 from the controller, and the motor 36 starts to turn a driven gear 35 via a main gear 37. As the gear 35 rotates, a supporting shaft 34 integral with the gear 35 rotates, and an upper guide rail 33 integral with the supporting shaft 34, the disc 1, and the guide rail 38 altogether rotate 180 deg.. Accordingly, for instance, the side A of the optical disc 1 is turned over and the side B is made up.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a disc exchanger that can automatically turn over a disc on which information can be recorded and reproduced on both sides A and B.

2. Description of the Related Art In recent years, with the rapid advancement and development of laser technology, disks capable of recording large amounts of information have appeared. In particular, there is a tendency to shift from single-sided recording to double-sided recording.

Problems to be Solved by the Invention In double-sided recording discs, there is a problem in that after one side of the disc is played back, the disc must be taken out of the device, turned over, and then set back into the device.

There are also devices that allow double-sided access, but they are configured to record and play back sides independently on side A and B, and the cost of having two recording and playback units increases.
An increase in shape is inevitable.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a disk exchanger that can automatically turn over a double-sided recording disk during playback.

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. That is, a carrier that receives any disc from a stocker storing a plurality of discs on which information can be recorded and reproduced on both sides is provided with means for automatically turning over the disc received from the stocker.

Operation: By turning over the disc provided on the carrier that receives any disc, the recording and reproducing section can access both sides in one unit.

Embodiment FIG. 1 is a schematic perspective view showing an embodiment of a disk exchanger according to the present invention, and FIG. 2 is an enlarged perspective view of the carrier shown in FIG. 1.

In FIGS. 1 and 2, 1 is, for example, an optical disk on which information can be recorded and reproduced on both sides A and B, 2 is a stocker that can store a plurality of optical disks 1, and 3 is movably provided on the front side of the stocker 2. This is a carrier that receives any optical disc stored in the stocker 2.

The carrier 3 has a structure as shown in FIGS. 1 and 2. That is, a case 32 having an inverted cross-section is fixed to the upper surface of the base 31, and an upper guide rail 33 that guides the upper end of the optical disc 1 is inserted into the upper edge 32b of the opening of the case 32 on the opposite side from the side wall surface 32a. Place. This upper guide rail 33 is rotatably provided via a support shaft 34. A driven gear 35 is provided on the support shaft 34, and this driven gear 35 supports the A side and B side of the optical disc 1.
It meshes with a main drive gear 37 provided on the shaft of a surface switching drive motor 36. An under guide rail 38 for inserting and guiding the lower end of the optical disc 1 is rotatably disposed on the base 31 at a position directly below the upper guide rail 33.

The carrier 3 constructed as described above is reciprocated on the front surface of the stocker 2 in the direction in which the optical disks are arranged by a transfer motor 4 such as a linear pulse motor.

In FIG. 1, 5 is a disk motor that rotates the optical disk 1 clamped by the upper guide rail 33 and the lower guide rail 38 provided on the carrier 3 at a specified rotation speed, and 6 is a disk motor that rotates the optical disk 1 at a specified rotation speed. It is an optical head that reads.

Next, the operation will be explained.

The optical disc in the stocker 2 located on the front side of the carrier 3 is inserted and pulled out between the upper guide rail 33 and the lower guide rail 38 of the carrier 3 by appropriate means. Therefore, first, both guide rails 33 and 38
The optical disc 1 which is clamped is recorded or reproduced via a disc motor 5 and an optical head 6. The A side or B side of the disc 1 to be recorded or reproduced is determined by an instruction from a controller (not shown), and if the direction of clamping is reversed, the controller (not shown) controls the optical disc 1.
The drive motor 36 starts and rotates the driven gear 36 via the main gear 37 by supplying the inversion signal to the drive motor 36 . As the driven gear 35 rotates, the support shaft 34 integrated with the gear 35 rotates, and the upper guide rail 33 integrated with the support shaft 34 rotates. The optical disc 1 and the under guide rail 38 rotate 180 degrees together. As a result, the A side of the optical disc 1, for example, is turned over to the B side.

In addition, the determination of A side and B side is that A side is on disc 1.

There is a method of attaching a mark that can be used to identify the B side and providing a function for detecting it with an optical sensor or the like.

Alternatively, there is also a method of determining in advance the direction in which the paper is to be stored in the stocker 2 and determining the A side and the B side based on the direction in the stocker 2 without using a sensor or the like.

When returning the disc 1 to the stocker 2, if the disc exchanger is equipped with a function to detect sides A and B of the optical disc, the optical disc that has been turned over can be returned to the predetermined position in the Skanote 2. However, if the above function is not provided, a certain side of the optical disc (for example, A
After storing the optical disc in the stocker 2 with the sides (side) aligned, turn the optical disc that has been turned over (side B) again by 180 degrees to turn it upside down (side A), and then return the optical disc to the predetermined position in the stocker 2. It's fine if you do.

Effects of the Invention As is clear from the detailed description above, according to the present invention, after a disc on which information is recorded on both sides is clamped and played back, the disc can be automatically turned over and played back. It is possible to eliminate such troubles.
