Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a disc insertion device for a disc player such as a video disc player or a compact disc player, and particularly to a disc insertion device for a disc player that uses a slot-in method. Regarding.

[Background of the idea]

Conventionally, in this type of disk player,
When a turntable is installed in a case with a built-in mechanism such as a playback device so that it can be moved in and out, and a disc with recorded information is attached to the player, the turntable is first sent out of the case, and then the disc is placed on the turntable. A commonly used method is to put the disc in place, insert the turntable into the case again, and then load the disc into a playback device. However, this method requires a large operating space on the front of the device, and as mentioned above, when installing the turntable, two operations must be performed, one for sending out the turntable and the other for inserting it, so the operation for installing the disk is difficult. The disadvantage is that it is complicated.

In recent years, in order to solve the above problems in use,
A horizontally long disc insertion slot is provided on the front of the case that houses the disc player's mechanism body.
The so-called slot-in method, in which a disc is directly inserted into the case through the disc insertion slot and then taken out directly from the disc insertion slot after play is finished, has been attracting attention. When using a disc player that adopts this slot-in method, there is no need to move the turntable in and out one by one as in the conventional case, so it is easier to install and remove the disc, improving operability, and the turntable can be easily inserted and removed. Since there is no need for a mechanism to take the player in and out, it is expected that the player will be able to be made smaller.

However, compact discs and video discs are difficult to handle because there is no space on the disc surface to hold them, and the disc surface is easily damaged by mechanical friction, so the slot-in method is used. However, there is a technical difficulty in that the disk insertion mechanism tends to be complicated and large. Due to these circumstances, a fully practical slot-in type disk player has not yet been provided.

[Purpose of invention]

An object of the present invention is to solve the problems of the conventional slot-in type disc insertion device described above and to provide a disc player with a simple and compact structure.

[Summary of the idea]

In order to achieve such an object, the present invention provides a pair of guide rails at a position facing the disk insertion opening in the case, with an interval that allows the disk to be inserted, and between the guide rails and the disk insertion opening. A loading roller that moves parallel to the front surface of the case to insert the disk into the case is provided, and an ejector roller that feeds out the disk is arranged behind the guide rail, and these loading rollers The invention is characterized in that the ejector roller is driven by one motor.

17 is a motor that drives the movable bodies 9 and 13;
8 is a worm fixed to the drive shaft of this motor 17, 19 is a worm wheel that meshes with this worm 18, and 20 and 21 are this worm wheel 1.
9 is a worm formed coaxially with the worm, 22 is a worm wheel that meshes with one of the worms 20, 23 is a worm wheel formed coaxially with this worm wheel 22, and 24 is one of the worms formed coaxially. A worm wheel 25 meshes with the other worm 21 and is formed coaxially with the worm wheel 24. The worm wheel 23 is engaged with a rack 6 carved in the left and right moving body 9,
Further, the worm wheel 25 is engaged with a rack 14 carved in the longitudinal moving body 13.

Next, the operation of the disc player of the above embodiment will be explained.

First, with the loading roller 5 at the right end in FIG.
into the case 1 through the disk insertion slot 2 of the case 1. When the disk A is inserted to a predetermined position, a motor operating switch (not shown) is turned on and the motor 17 rotates in the forward direction, causing the worm 18, worm wheel 19, worm 20, and worm wheel 2 to rotate.
2, 23 and the left and right moving body 9, the loading roller 5 starts moving in the direction of arrow 7 in FIG. At the same time, worm 18, worm wheel 19, worm 21, worm wheel 2
4, 25, the ejector roller 10 is moved to the arrow 15 in FIG.
Start moving in the direction of. Loading roller 5
When the disk A collides with the outer peripheral surface of the disk A and further moves in the direction of the arrow 7, the disk A is fed into the case 1 by the pressing force of the loading roller 5. At this time, the ejector roller 10 does not collide with the disk A, but sequentially moves toward the rear end of the case 1 as the motor 17 rotates.
When disk A is fed to a predetermined position, a motor stop switch (not shown) is activated to stop the motor 17, and then a vertical movement device (not shown) is activated to place disk A on a turntable (not shown). Then, a reproducing device (not shown) is activated to reproduce the recording recorded on disk A.

Conversely, when taking out the disk A stored in the case 1, when the operator operates the eject button (not shown), the up/down movement device (not shown) is activated and the disk placed on the turntable is inserted. Then, the motor reverse switch (not shown) is turned on and the motor 17
is reversed. When the motor 17 reverses, the eject roller 10 advances toward the disk insertion slot 2 side (arrow 16 side) via the worm 18, worm wheel 19, worm 21, worm wheels 24, 25, moving body 13, and revolving body 12. Start.
At the same time, the worm 18, worm wheel 19, worm 20, worm wheel 22, 2
3 and the loading roller 5 via the moving body 9
moves in the direction of arrow 8 in FIG. The ejector roller 10 abuts against the outer peripheral surface of the disk A, moves it forward, and stops at the original position where a part of the disk A is sent out from the disk insertion opening 2. This allows the operator to directly take out disk A from the player.

The gist of the present invention is a loading device that inserts a disk into case 1, and an ejection device that sends out a disk inside case 1 to the outside of the case, so that the disk inserted into case 1 can be transferred to the turntable. A detailed description of the device will be omitted.

Incidentally, in the above embodiment, the loading roller 5 of the loading roller and the ejecting roller is
In this embodiment, the ejector roller 10 is moved in the front and back direction of the case 1 (in the direction of arrows 15 and 16). The gist of the present invention is not limited to this, and similarly to the loading roller 5, the ejection roller 10 can also be configured to move in a direction parallel to the front surface of the case 1. In this case, the depth of the disc player can be made even smaller.

[Effect of idea]

As mentioned above, the disc player of the present invention is
The disk guide restricts the movement of the disk in the left-right direction, and the loading roller moves parallel to the front of the case to move the disk in the front-back direction of the case. It is possible to shorten the depth dimension of the case where the Further, since the disk insertion and delivery are automatically performed using the driving force of the motor, the disk insertion and delivery operations can be performed easily. Furthermore, since the disk can be inserted and ejected with one motor, the structure is simple and can be provided at low cost. Furthermore, the loading roller and eject roller are configured to be rotatable,
Since it comes into contact with the outer peripheral surface of the disk while rotating, there is no risk of damaging the disk surface.
