Abstract

PURPOSE:To prevent the flaw of a disk as well as noises generated by the open/ close of a cover by fitting the disk to a rotary shaft of a turntable to secure a play mode after putting the disk on an upwardly sloping disk stage and then closing the cover. CONSTITUTION:When a knob 7 is moved up to load/unload a disk 1, a cover 5 is turned upward as shown by an arrow head. At the same time, a disk stage 8 is turned in the opposite direction to the cover 5 to secure a disk loading/unloading position sloping upward and obliquely. In this case, the contact of a switch 15 is opened to stop th revolution of a turntable 2 as well as actions of other devices. Under such conditions, the disk 1 can be loaded to and unloaded from the stage 8. When a play mode is desired again, the cover 5 is closed to set automatically the disk 1 at a prescribed position on the table 2. This prevents the flaw generated when the disk 1 is loaded and unloaded. Furthermore no effect is produced at all from vibration caused by opening/closing of the cover 5 since a play mode is possible only when the cover 5 is completely closed.

Conventional configuration and its problems Conventionally used disc players are designed to place the disc directly on the disc mounting surface of the turntable, and in this case, the rotation center hole of the disc is aligned with the rotation axis of the turntable. I try to fit it in. However, since the area around the rotational center hole of the disk is almost opaque, when placing the disk on a turntable, it is very difficult to align the rotational axis of the turntable with the rotational center hole of the disk. The top surface of the disc often scratched the disc. In particular, when the turntable is larger than the disk, it is easy to locate the rotation axis on the outer periphery of the turntable, but on the other hand, when the disk is smaller than the turntable, this task is extremely difficult. Also, the signals recorded on disks are extremely small and delicate.
Dogs are greatly affected by scratches, fingerprints during handling, dust, and dirt in the air, which can cause noise during play, so be sure to prevent dust and dirt from adhering to your disc player. In addition, a cover is provided to prevent careless scratches, etc., and the cover is opened and closed as necessary, but the impact of vibrations etc. on recording and playback due to opening and closing of this cover cannot be ignored. There is something.

In the above configuration, in the play state, as shown in FIG. 6, the cover (5) is closed, the disc mounting table (8) serves as a horizontal play bag, and the disc holding surface α → is placed on the turntable (2). ), and the disc (1) rotates and plays as the turntable (2) rotates. Next, in order to attach and detach the disc (1), lift the handle (7) of the cover (5) completely.
As shown in Fig. 4, the cover (5) rotates upward as shown by the arrow and opens, and at the same time, the disk mounting table (8) also moves in the opposite direction from the cover (5) via lever α0 and link aυ. It rotates and assumes a disk attachment/detachment position that is tilted diagonally upward. At that time, the disc (1) is moved in the direction of the arrow, separated from the mat (2a) on the turntable (2), and is connected to the disc center hole (la) and the turntable rotation axis (
4) is released, the contact of the switch 00 is also opened, and the rotation of the turntable (2) and the operation of other devices are stopped. In this state, if you want to insert or remove the disc (1) from the disc mounting table (8), close the cover (5) and close the disc (5).
1) is at a specified position 1f on the turntable (2) at your own risk.
;, the value is set to i, and the play state is entered. Therefore, there is no risk of scratches occurring when the disk (1) is removed, and there is no noise caused by dust, dirt, etc. due to forgetting to close the cover (5). As for the neck, since the play operation does not occur unless the cover (5) is completely closed, there is no effect of vibration caused by opening and closing the cover. Furthermore, the disc mounting stand (8)
Since the disk (1) is inclined diagonally upward, it is easy to attach and detach the disk (1).In particular, since the cover (5) and the disk mounting table (8) each rotate in opposite directions around one end on the opposite side, the cover (5) is out of the way, and the disk (1)
It is very easy to attach and detach.

Effects of the Invention According to the disc player of the present invention, as is clear from the above description, the disc can be inserted into the turntable rotating shaft simply by placing the disc on the disc mounting table tilted upward and closing the cover. This allows you to play the disc without getting used to scratching it, and since the cover that prevents dust, dirt, etc. is always closed during playback, there is no noise caused by opening and closing the cover, and the cover does not get used to scratching the disc. Since there is no need to forget to close the disc, it has a great effect on the maintenance of the disc. In addition, discs can be easily inserted and removed, speeding up operations, and can be handled reliably without any prior knowledge, especially for children. C14 that can realize a player, Brief description of drawings Figures 1 and 2 show a conventional example, Figure 1 is a partially sectional side view in a playing state, Figure 2 is a partially sectional side view when a disc is attached and removed, 6 and 4 show an embodiment of the present invention,
