The present invention relates to a compact disc autochanger player equipped with a disc loaded with a plurality of discs in a disc player, and selectively loaded with a disc to be played on a turntable according to a driver's selection. An elevator apparatus for elevating a loading assay to select a disk.

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 above-described auto changer player 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, the disc loaded with a plurality of discs is mounted on the margin mounting portion of the auto changer player, and the loading assay 1 is lifted and operated to select the disc to be played, and then the selected disc 3 is selected as 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 in this way, 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 turntable 5 is rotated. At the same time as), 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 mounted on 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 lift and lower the loading assay 1 or to pull out the disk 3 by stopping at the correct position, the lifting means for raising and lowering the loading assay 1 should be configured to operate correctly.

Japanese Patent Laid-Open No. 63-217566 (published on Sep. 9, 2007) shows that the main chassis is equipped with a main body chassis in which a mechanism part is mounted and a margarine in which a plurality of disks are stacked. In the auto changer of a disc player having an insertion hole provided in the main body and a moving chassis installed in the main body chassis and moving in the stacking direction of the magazine, the entire chassis is mounted while protruding from the main chassis and the moving chassis to face each other in the stacking direction. The first and second protrusions which contact the front end of the disk to guide the front end of the disk are made to be freely displaced toward the stacking direction by the first protrusion arranged on the main chassis side, and by this means The disc player which is transmitted and presses the first projection in the opposite direction by the moving chassis to displace the projection during the movement of the moving chassis. Autochanger ", the main part of which is formed in which the pins protruding on both sides of the elevating chassis 11 are coupled to the elevating holes formed on both sides of the main body 12, as shown in FIG. The slide holes 13a and 13b coupled to the pins protruding from both sides of the elevating chassis 11 and the slide chassis 13a and 13b of the guide holes are connected to each other, and the spring 14 is connected to the intermediate point. A rotating lever 16 which is integrally squeezed with the hardened fan-shaped rack gear 15 and rotated left and right is constituted. As the pinion driven by the motor to the rack gear 15 rotates, the pivoting lever 16 rotates left and right, so that the two slide chassis 13a and 13b are moved in opposite directions to move the pins of the elevating chassis 11. By guiding, the elevating chassis 11 was raised and lowered so that the disc in the margin was selected, taken out, and played. However, in the above configuration, since there is no control means for raising and lowering the elevating chassis accurately and stopping at the correct position, many problems occur such that the user cannot accurately select and eject the disc to be played. Let's do it.

The contents of Japanese Patent Application Laid-Open No. 3-23036, which are devised to solve the above-mentioned problems, are formed by integrally forming a drive gear 21 capable of forward and reverse rotation and a slider gear 22 engaged therein as shown in FIG. On the stepped cam portions 24a and 25a, which are moved by the slider link 23 and the slider links 23, and the slide plates 24 and 25 are provided with stepped cam portions 24a and 25a.

And a slide 27 and a slide link 23 operated by a slide link 22 and a cam 23a provided with a plurality of position detection holes 22a and a cam 23a around the slide gear 22. And slide plate 24 having a stepped cam portion 24a or 25a. 25) is connected to the stepped cam portion 24a, 25a, and is configured by connecting a disk loading portion capable of vertical movement. However, since the operating state of the power transmission means is unstable, the position detection hole is provided in the slide gear. It was a reality that disc ejection was not performed properly because the up-and-down motion control of the disc loading part was very disadvantageous and the exact position was not set.

The present invention has been made in view of the above-described conventional defects, the slide operation is stabilized by allowing more guide holes to guide the operation of the slide chassis, the position sensing means is installed on the reduction gear so that the position of the loading part is determined. This facilitates the lifting positioning of the loading assay, which is a disk loading device, as well as the tolerance management of the drive gear or photointerrupter for driving the chassis, thereby improving the reliability of the product such as accurate operation and smooth operation. Its purpose is to.

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