Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording disc storage container for storing recording discs such as video discs, magnetic discs, etc. on which high-density recording is performed.

Structure of the conventional example and its problems The conventional recording disk storage container is disclosed in, for example, Japanese Patent Application Laid-open No. 56-11.
Most cartridges use a cylindrical cartridge, such as the one shown in No. 1158, and due to their construction, the recording disc storage container containing the recording disc is attached to the playback device, and then the empty recording disc storage container is played back. There were problems such as the need to manually take out the device from the device and the complicated configuration of the loading mechanism.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a recording disc storage that allows the recording disc to be automatically played back by simply attaching it to the playback device with the recording disc stored therein, without having to take it out from the playback device. The purpose is to provide a container.

Structure of the Invention In order to achieve the above object, the recording disk storage container of the present invention has one side facing the signal recording surface of a recording disk having a signal recording surface on one side, and has an open part on the other side and the side. a storage container body, an engagement body that removably engages with one side of the storage container body, and an engagement protrusion located on the other side of the storage container body that can engage with the recording disk. The structure is equipped with the following features.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a recording disc storage container according to an embodiment of the present invention, in which 1 is a recording disc, one surface 1a is a signal surface, and the other surface 1b has no signals recorded thereon. Furthermore, an engagement hole 2 is bored in the center. 3 is the main body of the storage container, which has a pin engagement hole 4, a claw 5 capable of holding the recording disc 1, a wedge engagement hole 6, a guide groove 7, a hole 8 large enough to allow the boss of the spindle motor of the playback device to pass through, and a notch. 9, and has a storage space 10 for storing the recording disk 1 as shown in the figure. Reference numeral 11 denotes an engaging body that can be engaged with the storage container main body 3, and includes a guide portion 12 that fits into the notch 9 and slides, a claw 13 that holds the recording disc 1, and a wedge that engages with the wedge engagement hole 6. 14, a plate spring 15, and a pin engagement hole 16. FIG. 2A shows a state in which this engaging body 11 is engaged with the storage container body 3 so as to hold the recording disc 1.

As shown in Fig. 2A, the storage container body 3 and the engaging body 1
1 are engaged, the recording disk 1 is held by the claws 5 and 13, and at the same time, the signal surface 1a is protected by the storage container body 3.

FIG. 2B is a perspective view of a reproducing apparatus using the recording disc storage container, in which 20 is a spindle motor for rotating the recording disc 1, and 21 is a shaft of the spindle motor 20, which engages with the engagement hole 2. Reference numerals 22 and 23 indicate engagement pins, which are fixed to the plate 24 and the release member 25, respectively. 26 is a solenoid configured to drive the pin 27, and the plate 2
It is fixed to a guide part 28 fixed to 4. A notch 29 is provided in the plate 24, and the spindle motor 2
It is configured so as not to interfere with 0. The release member 25 is configured to be slidable by fitting into the notch 29. The plate 24 and the release member 25 are provided with connecting portions 24a and 25a, respectively, and are connected by a connecting rod 32 via pins 30 and 31. The connecting rod 32 is rotated by a shaft 34 of a motor 33. The motor 33 is fixed to a stand 35. Guide parts 36 are provided on both sides of the stand 35,
The plate 24 is configured to be slidable on a stand 35 by guiding the plate 24. A gear 37 is formed at one end of the base 35, and is rotatably supported by a support portion 39 by a shaft 38 passing through the center of the gear 37. The support portion 39 is fixed to the chassis 40. A motor 41 drives a gear 42 that meshes with the gear 37, and moves the platform 35 around a shaft 38 as indicated by an arrow d in the figure. Reference numeral 43 denotes a reproducing pickup, which is moved by a driving means (not shown) as indicated by an arrow e in the figure, and is moved to the signal surface 1a of the recording disk 1.
Extract the signal from.

3A and 3B are explanatory diagrams of the operations of the plate 24 and the release member 25. In the state shown in FIG. 3A, when the shaft 34 of the motor 33 rotates in the direction of the arrow f, the connecting rod 32 rotates, and the plate 24 and the release member 25 connected by the connecting parts 24a and 25a are moved in the direction of the arrow g+h, respectively. direction, and the state shown in FIG. 3B is reached. Conversely, when the shaft 34 of the motor 33 rotates in the direction of arrow j, arrow k.

The plate 24 and the release member 25 slide in two directions,
Return to the state shown in FIG. 3A.

4A and 4B are explanatory diagrams of the operation of the solenoid 26.

In this figure, only the operation of the solenoid with respect to the storage container body 3 is shown for simplicity. When the recording disc storage container is attached to the playback device as shown by arrows a''-c in Figure 2, the fourth
As shown in FIG. A, the pin 27 of the solenoid 26 is in a state where it can push the wedge 14 through the engagement hole 6 of the container body 3. When the wedge 14 is pushed in the direction of the arrow m by the pin 27, the engagement between the wedge 14 and the engagement hole 6 is released, and the wedge 14 is pushed in the direction of the arrow n.

The storage container main body 3 and the engaging body 11 are slid relative to each other in the 0 direction to release the holding of the recording disc 1 by the claws 5 and 13.

All of the above operations are performed with the recording disc storage container attached to the playback device as shown by arrows a-Q in FIG. The engagement between the engagement hole 4, the engagement pin 23, and the pin engagement hole 16 never comes off.

FIG. 5 is an explanatory diagram of the operation of the main parts of the reproducing apparatus, and A shows a state in which the recording disc storage container is attached to the reproducing apparatus.

As shown in the figure, the recording disk 1 is connected to the shaft 21 of the spindle motor 20.
The storage container main body 3 and the engaging body 11 are fitted with the fourth
It is in the state shown in Figure B. Next, driven by the motor 41,
When the table 35 rotates in the direction of arrow q, it will be in the state shown in FIG. 5B. In this state, as can be seen from the figure, there is sufficient space for the reproduction pickup 43 to scan the recording surface 1a in the direction of the arrow p, and by rotating the recording disk 1 with the spindle motor 20, the signal is transmitted from the signal recording surface 1a. can be played. After the playback is finished, by simply performing the above-mentioned operation in reverse, the recording disk 1 is placed in the recording disk storage container and the signal recording surface 1a is protected, as shown in FIG. The disc storage container can be removed.

Further, the playback device can have a simple structure in which the mechanism shown in FIG. 2B is covered with an exterior case and has an opening for inserting and removing the recording disc storage container.

As described in detail, according to the present invention, a recording disk having a signal surface on one side can be easily stored, and the signal surface can be protected from dust, scratches, etc. Furthermore, by attaching the recording disc to the playback device while it is stored, it is possible to automatically play back the disc without having to take it out of the playback device.
