The present invention relates to a laser disc automatic continuous player which holds several laser discs and automatically plays them continuously when a user selects a desired disc from the outside.

Laser discs using a laser to read a record include a video disc player, a compact disc player, and a compact disc ROM.

Most of the above laser disc players are able to play one disc at a time. Therefore, when the user wants to play another disc, the laser disc player has to be stopped and replaced with a newly selected disc.

On the other hand, an automatic continuous system called a jukebox has been put to practical use in the past, and this jukebox accommodates a plurality of ordinary synthetic discs in the main body and assigns each disc with a unique code. When the user inputs the desired disc code, the ejector moves to the designated chord address, takes out the disc selected by mechanical operation, returns it to the turntable, and plays it back. In a way.

The jukebox described above has the practicality to allow the user to selectively play the contents contained in the multiple discs, but the disc has a display space of at least two layers because the disc is arranged up, down, left, and right. As a result, the mechanism for taking out the selected disk must also have a means for moving up, down, left, and right, which results in a complicated structure and a large size of the device.

In order to solve the above problems of the conventional jukebox, the present inventors arrange the disks in a vertical circle to form a round circle so that the entire structure can be easily accommodated in a narrow space to simplify the overall structure of the laser. Disc automatic continuous player has been proposed in Republic of Korea Patent Application No. 88-17706 and Utility Model Registration Application No. 90-1474 (hereinafter referred to as the earlier application of the present invention).

However, in the earlier application of the present invention, since the tension spring holding the disk is in direct contact with the disk, there is a high possibility that the surface may be damaged during the handling of the disk, and the outer circumference of the disk is almost in a groove accommodating the disk in a vertical position. There is a problem in that either side of the disk is worn out when the disk is taken out and inserted.

An object of the present invention is to provide a laser disc automatic continuous player that is improved so that the disc is handled quietly and smoothly without damaging the storage and withdrawal process of the disc to solve the above problems.

In accordance with the above object, the present invention includes a plurality of laser disks as a radial groove formed in the display rack of the rotating shelf, and the disk play part and the received laser disk to take out and play the laser disk around the rotating shelf to the outside. In the laser disk automatic continuous player consisting of a disk replacement unit to be drawn out to be solid, the receiving side support lever is installed in each of the plurality of radial grooves formed in the display rack of the rotating shelf is pressed by the tension spring, the receiving side The support lever has a groove into which the laser disk is fitted in an arc surface in contact with the laser disk, and a protrusion is formed inside the radial groove and the groove, respectively, and is arranged up and down in the disc play part. The guide channel of the pair is at least the lower guide channel. A groove is formed in the circular arc surface formed by the tension spring, and the projection side is formed in the inner side of the lower guide channel. It has a pair of guides installed so as to be rotatable up and down by means of elastic members, and the inner end is tensioned by an elastic member so that wear and tear of the laser disk can be prevented when the laser disk is taken out and replaced. do.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

It is suppressed upward by the tension spring 5 whose one end was fixed to the bottom surface of the display stand 2.

In addition, the receiving side support lever 4 has an arc surface 4a in contact with the laser disk D, and a groove 4b into which the laser disk D is fitted is formed in the arc surface 4a. It is.

Moreover, the groove 4b of the radiation groove 3 and the receiving side support lever 4 has the projection 30 and the projection 40 inside, respectively, as shown in FIG. The sharp outer periphery D 'prevents the radial groove 3 or the groove 4b from directly contacting the above.

Referring again to FIG. 3, the disc play portion B disposed on the outer circumference of the rotary shelf A has a loading arm 8 and an unloading arm 9 interlocked with the drive means 7, By selective driving of both arms 8 and 9, the laser disk D of the display rack 2 can be loaded into the playing position of the disk play section B or can be received back into the display rack 2 at the playing position. have.

The laser disk D is guided to the pair of guide channels 10 and 11 arranged up and down in the disk play section B, and among the lower guide channels 11, the receiving side support lever 4 is described. A performance side support lever 4 'similar to the < RTI ID = 0.0 > 1) < / RTI >

As shown in Fig. 6, the playing side support lever 4 'is formed with an arc surface 4a' in contact with the laser disk D. The groove 4b 'is similarly formed on the arc surface 4a'. ) Is given.

The lower guide channel 11 has a projection 20 therein that does not directly contact the outer periphery D 'of the laser disk D.

The performance side support lever 4 'and the projection 20 may also be attached to the upper guide channel 10 if necessary.

On the other hand, the ejection arm 13 which is operated by the drive means 12 is also provided in the disk replacement part C. As shown in FIG. And as shown in FIG. 7, the pair of guides 14 and 15 can be rotated up and down by the pins 16 and 17 to the inside of the door 1 facing the disk replacement part C. As shown in FIG. In addition to being installed on the plate (F), the inner end thereof is tensioned by the elastic members (18) and (19), respectively, so that when the door (1) is opened, the door (1) is opened to the outside.

The present invention configured as described above allows the user to select one of a plurality of laser disks D accommodated in each of the radiation grooves 3 of the display rack 2 and transfer the same to the disk play part B so that the user can play the present invention. As in the prior application of the present invention, the operation is performed by inputting and starting the position of the radiation groove 3 in which the desired laser disk D is accommodated outside the main body H.

The rotary lathe A rotates and conveys the laser disk D instructed by the user so as to coincide with the disk play portion B, and the driving means 7 of the disk play portion B is loaded with the loading arm 8 at this position. The selected laser disk D is guided between the upper and lower guide channels 10 and 11 via the receiving side support lever 4 and the playing side support lever 4 '.

In this process, the laser disk D includes the projections 30 formed in the radiating groove 3 of the display rack 2 and the projections 4b and 4b 'formed on both support levers 4 and 4' and the lower guide channel. Since it is guided on the protrusion 20 formed in the inside of the (11), the sharp outer periphery (D ') of the laser disk (D) does not make any contact with the surroundings to be transferred quietly and smoothly without causing any damages. Can be.

In addition, the laser disk D is guided to the disc play section B by the receiving side support lever 4 pressed against the tension spring 5 in the state of being accommodated in the radiation groove 3 of the display stand 2. In the state can be stably retained in the correct position and posture by the playing side support lever (4 ') suppressed by the tension spring (5').

Also, in the case of replacing any of the laser disks (C) housed in the radiation groove (3) of the display rack (2) with another one, the user opens the door (1) and then replaces the laser disk (D) to be replaced from the outside. The operation is instructed.

When the door 1 is opened, the guides 14 and 15 are respectively tensioned by the elastic members 18 and 19 so as to swing the pins 16 and 17 in the axial direction to be developed outward.

Next, the rotary lathe A rotates and conveys the laser disk D to be replaced to the position corresponding to the disk replacement portion C, and the drive means 12 of the disk replacement portion C operates at this position. As the take-out arm 13 is interlocked, the laser disk D to be replaced is led out to the guides 14 and 15.

The user collects the laser disk D taken out along the guides 14 and 15 and replaces it with a new one.

In this replacement process, both guides 14 and 15 limit the extraction position of the laser disk D so that the laser disk D does not fall out of the main body H and break.

In addition, when exiting between the laser disk (D) guides 14 and 15, the guides 14 and 15 are opened up and down against the elastic members 18 and 19.

The newly replaced laser disk D is received into the corresponding radiation groove 3 of the display rack 2 as soon as the user closes the door 1, and both guides 14 and 15 are folded up and down to the original state. Go back.

As described above, the present invention prevents the sharp outer periphery of the laser disk from being rubbed with the leading portion thereof in the ejection process of the laser disk, thus preventing the wear and tear of the laser disk and the problem of the transfer of the laser disk caused by the friction. This allows the laser disk to be removed and accommodated quietly and smoothly.
