Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a disc recording / reproducing apparatus for performing recording / reproducing on a compact disc, a video disc, etc., and in particular, a disc recording in which a part of the disc is pushed up in accordance with an opening operation of the disc to facilitate the taking out of the disc. Reproduction device

[Prior art]

In the conventional disc recording / reproducing apparatus, the disc accommodated in the reproducible state can be taken out by opening the upper lid.

[Problems to be solved by the device]

However, in the above-described conventional disc recording / reproducing apparatus, the space for accommodating the disc is very small, and it is difficult to set the disc in the case or remove the disc from the case. Therefore, although a device has been devised to make it easier to set and remove the disc by cutting out the side part of the case or a part of the upper lid, not only there is room for improvement in these operations, but also the case There is a problem in that the design is restricted because the appearance does not look good by notching a side part or a part of the upper lid. The present invention has been made in consideration of such a situation, and is restricted in design by lifting a part of the disk in accordance with the opening operation of the upper lid which is openably and closably provided with respect to the case. It is an object of the present invention to provide a disc recording / reproducing device that can easily set and eject a disc.

[Means for solving problems]

In order to achieve the object, a disc recording / reproducing apparatus of the present invention has a case for accommodating a disc at a recordable / reproducible position, an upper lid openable / closable with respect to the case, and interlocking with an opening / closing operation of the upper lid. And a lift plate on which a part of the disk is mounted, the lift plate having a guide wall for restricting the mounting posture of the disk, and the lift plate when the upper lid is in the closed position. So that the plate is substantially horizontal and the lift plate rotates at a set angle when the upper lid is in the open position,
It is characterized in that it is provided between the case and the upper lid.

【Example】

Hereinafter, details of embodiments of the present invention will be described with reference to the drawings. 1 to 6 show an embodiment of a disc recording / reproducing apparatus of the present invention, in which a case 8 for accommodating a disc in a reproducible state is provided with a chassis 8. Pivot portions are provided at both ends on the rear side of the case 4, and an upper lid 2 is pivotally attached to the case 4 via a fulcrum shaft 1. A lock hole 2a is formed on one side of the front portion of the upper lid 2. Chassis 8
A lock claw 7 corresponding to the lock hole 2a is provided on the side. The lock claw 7 is an open button 5 provided on the case 4 side.
When is pressed against the spring 6, it is released from the lock hole 2a. Therefore, when the normal pressing force of the open button 5 is not received, the lock claw 7 fits into the lock hole 2a. On one side of the upper lid 2, a tip end portion of an arc-shaped braked object (also serving as a lift lever) 19 inserted into a hole of the chassis 8 is fixed by a screw 3. As shown in FIG. 7, the braked body 19 has a shape in which the thickness increases toward the lower side. At a position surrounding the hole 20 of the chassis 8, a fork-shaped elastic support body 10 which is bifurcated is attached by a screw 12. A braking body 11 made of rubber or the like is attached to the elastic support body 10. The braked body 19 is provided so as to pass through the inside of the fork-shaped elastic support body 10, and the braked body is caused by contact friction caused by the thick portion of the braked body 19 touching the brake body 11.
Braking force is applied to the movement of 19. In addition, a screw is provided between the free ends of the fork-shaped elastic support 10.
14 are erected. The front end side of the screw 14 is screwed into one fork portion, and the base end side of the screw 14 slidably penetrates the other fork portion. A braking spring 13 is interposed between the other fork portion and the head of the screw 14. This makes it possible to adjust the gap between the braking body 11 and the braked body 19, which is the gap of the fork portion, by adjusting the tightening of the screw 14, so that the braking force adjustment during frictional contact becomes easy. On the other hand, a lift plate 15 is rotatably attached to the rear portion of the chassis 8 with screws 18. The lift plate 15 is provided with a guide 15b having a shape that follows the guide line of the disc, and when the disc is set on the chassis 8, the guide 15b positions it. Guide pins 15a are provided on the lower surface side of the lift plate 15. The guide pin 15a is used for the braking target 1 described above.
It is adapted to come into contact with a pressing portion 19a provided at the lower end of 9. Further, the chassis 8 is provided with a spring support shaft 8a on which a coil spring 9 is wound. One of the arms of the coil spring 9 is supported by the chassis 8 and the other is supported by the pressing portion 19a, and applies an upward elastic force to the braked body 19. Further, the lift plate 15 is provided with a through hole 15c, through which a stopper screw 17 whose lower end is screwed to the chassis 8 is inserted. A spring that urges the lift plate 15 downward is provided between the head of the screw 17 and the lift plate 15.
16 are interposed. Next, the operation will be described based on the above configuration. First, when the open button 5 is pressed with the upper lid 2 closed, the lock claw 7 is removed from the lock hole 2a. The elastic body of the spring 9 pushes up the braked body 19 to open the upper lid 2. In this opening process, both side surfaces of the braked body 19 come into contact with the brake body 11, and the braking force is received by the contact friction. The braking effect at this time is adjusted by adjusting the tightening of the screw 14 as described above. When the braked body 19 moves up to a certain range, the pressing portion 19a presses the guide pin 15a,
Lift plate 15 is lifted against spring 16. In this way, when the upper lid 2 is completely opened,
On the chassis 8, the lift plate 15 rotates about the screw 18 as a fulcrum by a push-up angle to lift a part of the disc. Immediately before the top cover 2 is completely opened, the opening force of the top cover 2 is gradually reduced by the braking force of the brake body 11 on the braked body 19, and the lift plate 15 that rotates in response to this is also gently moved. Since the disc is pivoted, the impact force peculiar to the spring is not applied to the disc. Further, since the lift plate 15 rotates so as to lift a part of the disc, it is easy to take out and set the disc when the upper lid 2 is opened. When closing the upper lid 2, the upper lid is pushed down against the spring 9 to lower the pressing portion 19a, and the lift plate 15 is also lowered by the action of the spring 16.
Therefore, a part of the disk placed on the chassis 8 is gradually lowered, and when the upper lid 2 is completely closed, the disk is kept in the set horizontal state. At this time,
The guide 15b of the lift plate 15 positions the disc. At this time, the lock claw 7 is fitted into the lock hole 2a, so that the upper lid 2 is held in the closed state.

[Effect of device]

As described above, according to the disc recording / reproducing apparatus of the present invention, the lift plate that rotates in accordance with the opening / closing operation of the upper lid is provided inside the case, and when the upper lid performs the opening operation, the disc is moved by the lift plate. Since the part is pushed up, the disk can be taken out and set without cutting out the side surface part of the case or a part of the upper lid as in the conventional case. Therefore, without being restricted by design,
Moreover, it is possible to easily set and take out the disc.
