Abstract

PURPOSE:To thin an information recording/reproducing machine by expanding a distance between a pair of half cases when external force is applied to the engaging part of at least one of the pair of half cases in the loaded state of the engaging part to a reproducing position. CONSTITUTION:The storing case body 6 has a pair of half cases 7, 8 opposed to both sides of a disk type recording medium 16 and the half cases 7, 8 are connected to each other so as to be mutually attracting in the thickness direction by an exciting means 22. At least one of the half cases 7, 8 has the engaging part 15 for receiving external force for extending the distance between the half cases 7, 8 against the energizing force of the energizing means 22 at the time of engaged with a prescribed member 4 in a recording/reproducing apparatus in the loading state of the body 6 to the recording or reproducing position. Since the outer diameter size of the insertion port of the storage case of a reproducing machine M, the size of a holder 5 in the height direction and a moving space obtained when the holder 5 carries the storing case up to a prescribed position can be reduced, the reproducing machine M can be thinned.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a recording medium storage container for storing a recording medium such as a disk.

(Prior Art) In recent years, for example, following the Compact Disc (CD), which is a digital playback type record, the CD-I is used for data playback. OM (Read 0nly Mem
ory) is popular.

CD-ROMs have a huge amount of information, about 540 MB, and are usually used as databases, so the occurrence of data errors has a large negative impact, and great care must be taken to avoid scratches, damage, or deformation of the disc.

For this reason, storage containers are increasingly being used that protect the disc and allow it to be played in a playback device in its original state.

FIGS. 6 and 7 show the state immediately before and at the time of completion of attachment to a reproduction device when a conventional storage container is used.

As shown in these figures, a spindle motor (not shown) is attached to a chassis 1 of a reproduction device M, and a turntable 3 is attached to this spindle motor via a spindle shaft 2. Further, a positioning pin 4°4 is attached to the chassis l.

Furthermore, the reproducing device M is equipped with a holder 5 that lowers and transports the storage container to a predetermined position after the storage container is drawn in.

The main body of the storage container 6 having a thickness of A set in the holder 5 is composed of a case upper surface part 7 on the upper side in the figure and a case lower surface part 8 on the lower side.

The case upper surface part 7 and the case lower surface part 8 are fixed to each other at their terminal edges, and the space formed by the case upper surface part 7 and the case lower surface part 8 is filled with a disk 1.
6 is stored.

A circular hole 9 is formed in the center of the case upper surface 7, a flange 10 is provided around one opening end, and the other opening is closed by a detachment prevention plate 11.

A clamping pulley 13 having a flange 12 at the end edge is fitted into the circular hole 9, and the clamping pulley 13 is connected to the flange 10 and the detachment prevention plate 1.
1 prevents withdrawal.

On the other hand, there is a center hole 1 in the lower part 8 of the case, which is large enough for the turntable 3 to pass through.
4 is formed, and a positioning portion 15 into which the tip of the positioning pin 4 is fitted into a position across the center hole 14.
, 1.5 are provided.

First, when the storage container 6 is inserted through a storage container insertion port (not shown) of the reproduction device M, the storage container 6 is transported to a predetermined position by the holder 5. Next, the storage container 6
When the state shown in the figure changes to the state shown in FIG. 7, the tips of the positioning pins 4 are fitted into the respective positioning recesses 15 of the case lower surface 8 and positioned, and at the same time, the disc 16 is moved between the clamping pulley 13 and the turntable. It is rotatably clamped by 3.

After that, when the disk 16 in the storage container 6 is rotated by the driving force of the spindle motor via the turntable 3,
Information is read by a pickup head (not shown).

Incidentally, in recent years, there has been a trend for the reproduction device M having such a configuration to be made thinner. However, in the case of the storage container 6 having the thickness A described above, it is necessary to secure a movement space corresponding to the thickness A before it is installed in a predetermined position in the reproduction equipment M. Also, the thickness A of the storage container 6 is an obstacle to making the reproduction device M thinner.

(Problems to be Solved by the Invention) As described above, the conventional storage container described above is an obstacle to making recycled equipment thinner.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a recording medium storage container that allows information recording/reproducing equipment to be made thinner.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the recording medium storage container of the present invention can be used in an information recording and reproducing device with a disk-shaped recording medium stored inside the storage container main body. In a recording medium storage container that is installed at a recording or playback position, the storage container main body has a pair of half cases facing each other on both sides of a disk-shaped recording medium, and the pair of half cases are biased in the thickness direction by a biasing means. The biasing means is connected to each other so as to attract each other, and is engaged with a predetermined member in the recording/reproducing device with the storage container main body attached to at least one of the pair of half cases at the recording or reproducing position. It has an engaging portion that receives an external force for increasing the distance between the pair of half cases against the urging force of the half case.

(Function) In the recording medium storage container of the present invention, when the engaging portion of at least one of the pair of half cases is subjected to an external force while attached to the recording or one playback position, the distance between the pair of half cases is increased. Therefore, a predetermined clearance can be secured to allow the recording medium to rotate when recording or reproducing information.

Therefore, until the storage container body is attached to the predetermined position of the information recording/reproducing device body, it is only necessary to secure a movement space for the thickness of the storage container body within a predetermined thickness. It is possible to reduce the thickness of each component, shape, etc. associated with transportation of the main body.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIGS. 1 and 2 show an embodiment in which the recording medium storage container of the present invention is applied to a disk storage container. Note that parts common to FIGS. 6 and 7 are denoted by the same reference numerals, and redundant explanations will be omitted.

As shown in these figures, the disc storage container main body 6 is
It is composed of an upper half case 7 and a lower half case 8.

The upper half case 7 has a protrusion 18 having a small protrusion 17.
,18. ...is provided. Lower half case 8
includes a rib 19 that secures a storage area for the disk 16, etc.;
A protrusion support part 21.21. has a protrusion insertion hole 20 with a diameter large enough to allow the protrusion 18 to slide when inserted, and a positioning recess 15. ...and center hole 14
Or is provided.

The positioning recess 15 of the protrusion support part 21 is large enough for the spring 22 to fit into it, and when the spring 22 is fitted, the protrusion 18 is inserted into the small protrusion insertion opening 24 of the stopper 23.
The small protrusion 17 is fitted.

Next, the operation of the disk storage container main body 6 having such a structure will be explained using FIGS. 3 to 5.

First, when the storage container is inserted into the storage container In1 of the reproduction device M, it is pulled in by the holder 5 and then lowered and transported to a predetermined position.

At this time, first, the protrusion 1 of the upper half case 7 of the storage container
The small protrusion 17 of 8 contacts the tip of the positioning pin 4.

When the storage container further descends, the small protrusion 17 is pushed upward against the biasing force of the spring 22. Then, the tip of the pin 4 fits into the positioning recess 15, and positioning is completed.

As a result, the initial thickness B of the storage container becomes A, which is the same as the thickness of the conventional storage container.

At the same time, the disc 16 is rotatably clamped by the clamping pulley 13 and the turntable 3.

After this, the disc 16 in the storage container is placed on the turntable 3.
When the pickup head P receives the driving force of the spindle motor S and rotates, the information is read by the pickup head P.

As described above, in this embodiment, the upper half case 7 and the lower half case 8 are telescopically overlapped via the spring 22, and the thickness B is set such that the disc 16 can normally be accommodated. Since the outer diameter of the storage container insertion opening a, the height dimension of the holder 5, and the movement space for the holder 5 to transport the storage container to a predetermined position can be reduced, the recycling device M can be made thinner. can be achieved.

In addition, in this embodiment, since the storage container normally maintains a state of thickness B, the clearance for the disk 16 inside the storage container is set to the minimum necessary, so that damage to the disk 16 due to vibration during transportation is avoided. It can also be prevented.

Furthermore, in this embodiment, since the thickness of the storage container can be reduced, the storage space of the storage container can also be reduced.

[Effects of the Invention] As explained above, according to the recording medium storage container of the present invention, it is possible to reduce the thickness of each component and the shape that accompany the transportation of the storage container main body. This allows the information recording/reproducing device to be made thinner.
