Abstract

PURPOSE:To select automatically a disk stored in a box, by providing an up- down frame which encloses a turntable, an RAFOC (radial and focus) unit, a pressure ring, etc. and moving up and down with a proper up-down means. CONSTITUTION:An up-down frame 17 encloses a turntable 12, RAFOC unit 14 and a pressure ring 15 which form a player main body 1. A proper up-down means is provided to the frame 17. The ring 15 is mechanically connected to the frame 17 so that the ring 15 is pushed up with the rise of the frame 17. In addition, the frame 17 contains a compact disk loading means to load a compact disk CD from the side direction while the frame 17 moving up. The loaded disk CD is set on the table 12 with a down movement of the frame 17.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a player body in a compact disc auto player.

With the development of compact disc players, there is a strong demand for small auto players that can automatically select and set compact discs.

The purpose of the present invention is to satisfy such a demand,
In addition, in order to provide a player body that can be used well for the auto player, we have developed an elevating frame that surrounds the player body that includes a turntable, a rack unit, and a pressure ring. The above-mentioned pressure ring is mechanically linked to the lifting frame so that it can be pushed up by the rise of the lifting frame, and the lifting frame is provided with an appropriate means for raising and lowering the lifting frame. The present invention is characterized in that a compact disc obtaining means is provided for introducing the compact disc from the side, and the introduced compact disc is set on the turntable by lowering the elevating frame.

The illustrated embodiment will be described below.

FIG. 1 is an overall view showing the mechanical structure of the compact disc auto player. In the figure, 1 is the player body, 2 is the elevator adjacent to the right side of the player body, and 3 is the player body. A disc box 4 is installed in the elevator at a removable position and has a plurality of disc trays 31 inside so that all discs can be inserted and removed.
This is a carrier for supplying a selected one of the disc receiving trays 31 to the player main body 1, which is located at a predetermined height and in contact with the back of the player 2.

As shown in the exploded view of FIG. 3, the player main body 1 includes a turntable 12 disposed on the upper part of a chassis 11, a motor 13 for driving the turntable 1 provided below the turntable, and a motor 13 disposed beside the turntable. Equipped with Rahotsk unit 14 and pressure ring 15 on the turntable.
The pressure ring is rotatably supported by an arm-shaped holder 16 pivoted at the rear of the chassis 11, and a square lifting frame 17 is arranged around the turntable and the rack unit. Place the lifting frame on chassis 1
] or it can be detached from the outside by the lid 18.

The turn table 12 is made of a magnetic material, and the pressure ring 15 is made of a permanent magnet.
As is already known, the unit 14 includes a light ben 1 that optically reads the uneven surface of a compact disc.

The pressure ring holder 16 is bent in the middle into a 〈 shape, and a spring 162 is provided in the pivot portion 161 to bias it downward.

The elevator frame 17 has bosses 173 and 174 with base holes 171 and 172 on the inner surfaces of the front wall 17a and the rear wall 17b, and an oblong disk tray insertion opening 175 at the top of the right wall 1.7c on the elevator side. A front wall 1.7 is provided and connected to the insertion port.

Disc tray feeding detector 179 on the inner surface of the left side wall 1.7d
8k, a disk tray delivery detector 179b is provided on the outer surface of the right side wall 1.5c. Note that the delivery detector 179b may be provided on the elevator 2 side.

As shown in FIG. 4, the disk trays 31--... have a rectangular planar shape that fits the elevator frame 17, are thin, and have a circular recess 311 on the top surface into which a compact disk CD is fitted. A window hole 312 is provided at the center of the recess and on the side of the center, through which the turntable 12 and the hook unit 14 are movably inserted, and a compact disc CD is housed in the recess 311.

The lifter 18 has a pair of screw rods 181, 182'e that stand up at appropriate positions on the chassis 11, and bearings 183, 184t at the bottom, and screws the screw rods into the bosses 173, 174 of the lifting frame 17, respectively. At the bottom end of the screw and rod, respectively! J-185,186

A position detector 180 for taking out the cold air is installed in A'.The belt 189 may be a timing belt.

Next, the operation will be explained with reference to FIG. 1 and raise the elevator frame 17. When the upper limit is reached, the position detector 180 reaches 4@++ and the rise stops J1, and along with the rise, the arm 16 of the pressure ring 15 is pushed up and the pressure ring 15 floats up.
