Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a pressure arm interlocking mechanism for a compact disc player that automatically drives a pressure arm for pressing a compact disc against a player body of a compact disc player.

[Prior art]

PCM compact disc players, which belong to the digital audio category, have small discs and can store a large amount of information, so they can play continuously for long periods of time.

However, traditional compact disc players
The disk must be manually loaded onto the player body, but if automatic loading is possible, automatic performance for an even longer period of time would be possible. For this reason, automatic performance is possible by applying the gripping arm used in conventional automatic performance devices for LP records, but the radius of movement of the gripping arm is large and the entire device becomes large, making it difficult to play compact discs. This results in the player's strengths being halved.

Further, even if the compact disc can be automatically mounted on the player body, the pressure arm that presses the disc against the player body must be manually rotated by the operator.

[Purpose of invention]

In consideration of the above facts, the present invention aims to provide a loading device for a compact disc player that can automatically operate a pressure arm to press a compact disc mounted on the player main body.

[Summary of the idea]

In the loading device according to the present invention, a compact disk is housed in a tray, and while the moving table carrying the tray moves to the tray loading position on the player body, the moving table is engaged with the pressure arm to rotate the pressure arm, The compact disc is pressed against the player body.

[Example of idea]

As shown in Figures 1 and 2, the side wall 1 is placed on the base 10.
2 and 14 are erected, and a player body 16 is provided between these side walls 12 and 14. side wall 1
Guide elongated holes 18 and 20 are bored in the holes 2 and 14, respectively. These elongated holes 18 and 20 have a horizontal portion and a vertical portion, and a pin 24 protruding from the movable table 22
is inserted and guided through this elongated hole, making it movable.

This pin 24 is moved from the position shown in FIG. 1 to the position shown in FIG.
2 is in the position shown in Fig. 1, from the supply device not shown to arrow A.
The loading position of the tray 26, which is fed onto the moving table 22 in the direction shown in FIG. This is the position where it is mounted on the No. 16 turntable 30.

For this purpose, a circular hole 32 is bored in the center of the tray 26, and a positioning pin 34 protrudes from the turntable 30.

The pressure arm 36 is pivoted to the side walls 12 and 14 by a pin 38, and is configured to rotate from the positions shown in FIGS. 1, 2, and 4 to the position shown in FIG. . For this reason, a magnet is provided at the tip of the pressure arm 36 to attract it to the turntable 30, but an elastic body may be used to bias it.

A U-shaped groove 40 corresponding to the elongated holes 18 and 20 is formed in the pressure arm 36. This U-shaped groove 40 can accommodate the pin 24 in a state where the pin 24 has moved the maximum amount in the horizontal direction as shown in FIG. Rotate until.

Next, the action will be explained.

In the state shown in FIGS. 1 and 2, the tray 26 is fed in the direction of arrow A and mounted on the moving table 22. The moving table 22 is moved from the state shown in FIG. 4 to the state shown in FIG. 5 by a driving means such as a motor (not shown).

This causes the pin 24 to move to the pressure arm 36.
The pressure arm 36 is engaged with the U-shaped groove 40 of the pressure arm 36 to apply rotational force to the pressure arm 36. The pressure arm 36 is the fifth
As shown in the figure, the compact disc 28 is pressed onto the turntable 30 and becomes ready for playing.

The motor within the player body 16 rotates, and a signal on the back side of the compact disc 28 is read by the operation of a not-shown rack unit to start playing. After the performance is over, the operation returns to the state shown in FIG. 1 in the reverse order.

[Effect of idea]

In this way, the pressure arm 36 is attached to the moving base 22.
Since it automatically rotates when the compact disk 28 is moved, there is no need to manually operate it, and if the feeding of the compact disk 28 is automated, all operations will be automated.
