The present invention relates to a compact disc auto changer player configured to mount a margin loaded with a plurality of discs on a display, and to automatically load a disc to be played on a turntable according to a driver's selection. A loading apparatus for loading a compact disk loaded in a turntable.

In recent car audio systems, when installing a compact disc player for using a compact disc (CD) capable of playing a higher quality sound, a margin with a large number of compact discs is mounted, and according to the driver's preference. The auto changer player has been put to practical use.

The general structure of the autochanger player described above will be described with reference to FIG.

A large number of compact discs are stored and loaded with a compact disc auto changer player, which is then loaded with a number of compact discs to suit the driver's taste.

In this way, a plurality of discs loaded with margin are mounted on the margin mounting portion of the auto changer play, and the loading assay 1 is moved up and down to search and select the disc to be played, and then the selected disc 3 is pulled out by a pair of take-out rollers. (4a) (4b) rotates and loads to the turntable 5.

When the disc 3 is loaded on the turntable 5 as described above, the loading assay 1 descends so that the clamper 6 mounted on the loading assay 1 clamps the disc 3 so as to be rotated and the turn 5 As the c) rotates, the pickup 9 moves to read the record recorded on the disc 3.

In this configuration, in order to search and select the disk 3 loaded in the margin 2 and to load it on the turntable 5, the loading assay 1 is lifted and stopped at the position of the disk to be correctly selected. You have to.

As described above, in order to load the disk 3 loaded in the margin 2 and stop the loading assay 1 by lifting and lowering the disk position loaded on the turntable 5, the loading assay 1 is installed in the loading assay 1. When the plate is advanced to push the margin lever installed in the margin 2, the margin lever is rotated to push the disk 3 out of the margin 2, and the disk 3 pushed out of the margin 2 is taken out of the roller 4a. It is taken out by (4b).

As such, there is a loading device for extracting a disc loaded in a margin and loading it on a turntable, but there is a patent application No. 89-9537, which is a prior application of others, which is a plurality of discs as shown in FIGS. A margin mounting portion 11 into which a male butterfly 12 is inserted, and a disk taking-out mechanism 20 which opposes the disc outlet port and withdraws the disc 3 in the margin 12; A loading plate 21 for extruding the disk 3 in the margin 12 to the take-out roller 24 of the take-out mechanism 20 is installed to reciprocate in the disc extrusion direction, and then the disk 3 in the margin 12 In the disc changer-integrated disc player equipped with a disc taking-out mechanism 20 which is lifted up and down on the disc outlet side of the hemp 12, the margin mounting portion 11 has a margin 12 on its upper surface. Mounted A margin table 13 is installed, a lock plate 14 for fixing the margin 12 and an eject lever 15 for discharging are installed on the lower side of the margin table 13, and the loading plate 21 is empty. The moving piece 21a for operating the lock plate 14 when the lower side of the lower part 12 is moved to a process position is constructed and installed, and the margin table 13 is provided in the lock groove on the bottom surface of the margin 12. An eject lever 15 supported by a spring 16 is installed to install a lock plate 14 formed so that the defective lock pin 14a protrudes upward, and is pressed against the outside of the margin mounting portion 11 when the margin 12 is inserted. Was installed.

Here, the eject lever 15 is formed with a guide portion 15a for guiding the operation of the lock plate 14.

Here, the lock plate 14 is supported by the spring 17 toward the disc take-out roller 24, and when the margin 12 is released, the loading plate 21 moves forward and is integrally provided with the loading plate 21. While the operating piece 21a pushes the locking piece 14b of the lock plate 14 to release the closed lock state, the eject lever 15 is retracted by the elastic force of the spring 16 and the margin 12 is taken out.

In addition, when looking at the loading means for loading the disk 3 in the margin 12 mounted on the margin mounting portion on the turntable, the cam configured to interlock with each other by the power of the motor 22 for driving the disk take-out roller 24 The cam pin 23a is installed on the gear 23, and the guide hole 21a of the rear body is coupled to the cap pin 23a so that the front end of the tip trough 21b is closed while moving forward and backward as the cam gear 23 rotates. The disc housed in the margin 12 is selectively taken out by pushing the margin lever 26 installed in (12).

That is, when the motor 22 rotates, the guide gear 21a is coupled to the cam pin 23a of the cam gear 23 while the cam gear 23 interlocked with the motor gear 25 is engaged. As the loading plate 21 is advanced, the tip 21b of the tip pushes the lever 26 to rotate.

The Margin lever 26, which is pushed by the loading plate 21 and rotates, pushes the disc 3 contained in the margin 12 and pushes it out of the margin. At the same time, the feed roller 24 moves the disc 3 to the turntable side for loading. Done.

However, in the above-described conventional configuration, the power transmission means for moving the loading plate forward and backward is composed of a cam pin and a guide hole so that the contact parts are worn and the loading plate does not operate properly for a long time. There is a limit to the stroke selection because it is limited to the cam pin rotation radius of the gear, there are many problems, such as the disc is not re-stored in the same receiving groove in the margin before returning again when the margin lever of the margin is advanced when the disk is taken out.

In view of the above-described conventional defects, the present invention freely restricts the stroke of the forward and backward movements of the loading plate by setting the power transmission device for converting the rotational force of the motor into the rolling motion of the loading plate as the rack and the pinion. With the sliding tip of the loading plate being the sliding surface with tension, the disc is taken out from the margin and the sliding surface of the loading plate slides away from the margin lever so that the margin lever of the margin is always in the original position and ready for storing the disc. The purpose is to make the disk loading means and operation more smooth and smooth.

In order to achieve the above object, the present invention provides a compact disc autochanger player equipped with a plurality of disc-loaded margins, and configured to selectively take out a disc loaded in the margin and load it on a turntable to play.

And a loading device which is installed on the upper side of the turntable of the playing section and lifts the disk loaded in the margin, and selectively loads the loaded disk onto the turntable, wherein the loading device is configured to take out the disk loaded in the margin. The takeout means and the marginal disks convey the ejected disk to the turntable side. It is configured by the ding means so that their operation is made by the driving of a single motor, the extraction means, the loading plate is operated by the rack gear is engaged with the pinion rotated by the driving force of the motor, and is placed on the tip of the loading plate Margarine lever for pushing the disc inside the margarine, the loading plate, the tension engaging portion bent at the front end integrally formed so as to be separated from each other after some interference with the margarine lever.

When the present invention is described in detail according to the embodiment as follows. As shown in FIG. 6, a margin mounting part 11 on which one side of the main chassis 30 is equipped with a margin 12 containing a plurality of disks 3 is formed, and one side of the margin mounting part 11. A loading apparatus for elevating the compact disc auto changer player having the turntable 5 installed thereon, the disk 3 in the margin 12 mounted on the margin mounting portion 11, and lifting and lowering operation. It is configured as shown in FIG.

Here, the loading assay 50 constituting the loading device is a loading means for taking out the disc 3 loaded in the margin 12 and a loading means for moving the taken out disc 3 to the turntable 5 for loading. Here, the take-out means is a rack 61 is engaged with the pinion 52 that is rotated by the power of the motor 51 is formed, the end of the accompanying drawing forming the tension engaging portion 62 is bent It is composed of a loading plate 60, such as 8 degrees, the loading means is a pair of feed roller 54 is rotated by receiving the driving force of the motor 51, the disk 3 is conveyed by the feed roller 54 It consists of the guide 53 which guides.

The present invention as described above is to take out the disc 3 of the margin (12) mounted on the margin mounting portion 11 to load on the turntable (5) according to the driver's choice, first loading loading assay 50 equipped with a loading device While the elevating operation is performed, the disc 3 loaded in the margin 12 is selected and then stopped at the selected disc position.

In the stopped state, the loading device installed in the loading assay 50 is operated to take out the disc 3 in the margin 12 and load it on the turntable 5, which is shown in FIG. According to the following.

First, as shown in FIG. 9 (a), when the disc loading mode is set in a state in which the loading plate 60 is retracted as much as possible, the pinion is engaged to be interlocked with the motor 51 while the motor 51 is driven. As the 52 is rotated, the loading plate 60 in which the rack 61 is engaged with the pinion 52 is advanced.

As shown in FIG. 9 (b), the advanced loading plate 60 is a rear end of the margarine lever 70 installed so that the tension engaging portion 62 bent at the front end is pivoted on the margarine 12. Will push 71.

As shown in FIG. 9 (c), the margarine lever 70 in which the jaw 71 is pushed against the tension engaging portion 62 of the loading plate 60 is used to load the disc 3 loaded in the margarine 12. The disk 3 is pushed out and discharged to the outside, and is loaded onto the turntable 5 by a feed roller 54 which is engaged and rotated by the motor 51 and the electric gear 56 and the motor 51 at the same time. The loading plate 60 in which the rack 61 is engaged by the drive of the pinion 52 which is interlocked with the) continues to move forward, so that the bent ten-tapped portion 62 of the tip is close to the rear end of the lever 70. Departing from), the ground lever 70 is returned to its original state by the elastic force of the spring 72 and is ready to receive the disc, as shown in FIG. 9 (d).
