DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention takes out a disk from a disk cartridge containing a small-sized disk-shaped recording medium (hereinafter, abbreviated as "disk") and supports a disk larger in size than the small-sized disk. The present invention relates to a disk cartridge adapter capable of mounting a small-sized disk in a drive device.

[0002]

2. Description of the Related Art With the rapid development of computer technology,
Discs are widely used for recording / reproducing various information. A disc includes a recording layer on which information is recorded and a substrate portion supporting the recording layer, and there are many types of standards that specify the recording density, size, recording / reproducing method, and the like of the disc. For example, there are 80 mm diameter disks and 120 mm diameter disks. A disc is used by being inserted into a recording / reproducing device (drive device) for recording / reproducing / erasing information, and therefore there are many types of drive devices according to various standards.

[0003] On the other hand, in order to keep the recording surface side of the disk from becoming dirty, various types of disk cartridges have been developed in which the disk is housed in a case and used.

[0004] Under such circumstances, it is convenient for a user if a single disc drive can be used by inserting one disc having a different size into a disc cartridge. To realize this, for example, a small-sized disk taken out of a small-sized disk cartridge is stored in a cartridge adapter having the same dimensions and outer shape as a large-sized disk cartridge, and recorded by a drive device for a large-sized disk cartridge.・ Reproduction and erasure are under consideration.

Hereinafter, with reference to FIGS. 11 to 13, a non-disclosed disk cartridge and disk cartridge adapter prototyped by the present inventors before the present invention is completed will be described.

First, reference is made to FIG. 11 and FIG. These figures show a disc 1 having a diameter of 80 mm, a disc holder 75 for supporting the disc 1, and a disc cartridge 70 into which the disc 1 and the disc holder 75 are inserted.
Is shown. FIG. 12 shows a shape in which the upper half of the cartridge case 71 is removed. The disc 1 is inserted into the disc cartridge 70 while being held by the disc holder 75, and is rotatably stored in the storage section 72. A predetermined gap is formed between the storage section 72 and the disk 1. This gap is
Of the disk cartridge 7
The disk 1 is designed to be securely mounted on a motor or the like when 0 is inserted into the drive device.

The cartridge case 71 has an opening 73
The opening 73 is opened and closed by a shutter 74 movably provided along the front end of the cartridge case 71.

The disk holder 75 has a main body 76 and a disk support 77 extending from the main body 76, and can be inserted into and removed from the cartridge case 71. At both ends of the main body 76, locking portions 78 are provided.
As a result, the disk holder 75 is locked to the cartridge case 71. The locking portion 78 is elastically deformed by applying a force. This elastic deformation causes the disk holder 75
Can be released from the state locked by the cartridge case 71.

The grip 81 is formed thicker at the center of the main body 76 than at other portions. The grip portion 81
It is designed so that the user can grip the disk holder 75 when attaching or detaching it from the cartridge case 71 or when attaching or detaching it from the case main body 91 of the disk cartridge adapter 90 described later.

The disk support 77 has the above-mentioned predetermined gap with the disk 1 and is formed so as to surround a part of the outer shape of the disk 1. The disk support 77 is provided with a disk holder 79 for holding the disk 1. The disk holding portion 79 projects inward and laterally from the upper and lower surfaces of the disk support portion 77, and the disk 1 does not separate from the disk holder 75 even if the disk holder 75 is removed from the cartridge case 71.

Next, the disk cartridge adapter 90 will be described with reference to FIG.

The disk cartridge adapter 90 is designed by the present inventor so that the disk 1 and the disk holder 75 removed from the disk cartridge 70 can be housed inside the case body 91.
The cartridge adapter 90 has the same dimensions and outer shape as a large-sized disk cartridge for a 120 mm disk, and can be mounted on the disk cartridge drive device.

At the rear end of the case body 91, a disc 1 is mounted.
In addition, an opening 92 through which the disk holder 75 can be inserted and removed is formed. The opening 93 is provided with a notch continuously to the front end in the radial direction of the disk, and a head and a disk motor (not shown) are inserted therein.

A disk holder 75 is provided in the case body 91.
A guide wall 97 that functions as a guide when inserting a. A shutter 94 for closing the opening 93 is provided movably along the front end of the case body 91, and is urged by an elastic member 95 in a direction for closing the opening 93.

The opening / closing lid 96 is rotatably mounted on the case body 91. After the disk holder 75 is inserted into the case main body 91, the opening / closing lid 96 can close the opening 92 and position the disk holder 75 at a predetermined position on the case main body 91.

Next, the operation will be described. The disk holder 75 can be taken out of the cartridge case 71 by grasping the locking portion 78 by hand and applying a force inside, whereby the locking portion 78 is elastically deformed. At this time, the disk 1 is naturally taken out at the same time. Next, when the removed disk holder 75 and the disk 1 are inserted into the opening 92 of the disk cartridge adapter 90, the disk holder 75 is guided by the guide wall 97 and enters the inside of the case body 91. When the opening / closing lid 96 is rotated and the opening 92 is closed, the disk holder 75 is positioned inside the case main body 91. The disk 1 is also positioned at the same time.

When such a disk cartridge adapter 90 is inserted into a drive device corresponding to a large-sized disk cartridge, the shutter 94 moves in conjunction with the insertion operation, the opening 93 is opened, and the head is opened. And various information can be recorded / reproduced / erased.

[0018]

In the above arrangement, the disk support 77 is configured to be elastically deformable. Therefore, by elastically deforming the disk support 77,
The disk 1 can be easily removed. However, if the rigidity of the disk support 77 is low, the disk 1 may accidentally fall out of the disk holder 75.

On the other hand, in order to increase the rigidity of the disk support 77 so that the disk 1 cannot be easily removed, the thickness of the disk indicator 77 in a direction parallel to the main surface of the disk 1 must be increased. Conceivable. However, if the thickness is increased, the disc cartridge 70
Becomes large, and a practical disk cartridge cannot be realized.

When the rigidity of the disk support 77 is increased, the disk 1 may pass through the disk holder 79 and be housed in the disk support 77 when the disk 1 is assembled to the disk support 77. It becomes difficult.

Therefore, since the disk support portion 77 needs to be provided with elasticity optimal for removing the disk 1, after the disk holder 75 is removed from the disk cartridge 70, the user can use the disk holder 75. There is a possibility that the disk 1 is removed from the disk. Further, there is a possibility that the disc 1 is directly inserted into the disc cartridge adapter 90 alone (without the disc holder 75) and the opening / closing lid 96 is closed by the user. In this case, the movement of the disk 1 is
And the opening / closing lid 96, but since the disk holder 75 does not exist in the case main body 91, a correspondingly large gap is formed.

As described above, the disk cartridge adapter 90 has a problem that the disk 1 cannot be properly positioned.

Further, after the user inserts only the disk 1 into the disk cartridge adapter 90, the user may insert the disk holder 75 into the disk cartridge adapter 90 subsequently. In such a case,
It is necessary to realize smooth insertion of the disc holder 75 so that the disc holder 75 appropriately holds the disc 1.

Further, in the above-described disk cartridge adapter 90, there is a possibility that the disk holder 75 and the disk 1 drop from the disk cartridge adapter 90 with the opening / closing lid 96 opened.

The present invention has been made in view of the above circumstances, and has as its object the object of the present invention when a user removes a disc from a disc holder and inserts only the disc into a disc cartridge adapter.
Another object is to provide a disk cartridge adapter that can be used even when a disk holder is inserted after only a disk is inserted into the disk cartridge adapter.

It is another object of the present invention to provide a disk cartridge adapter in which the disk holder and the disk do not drop from the disk cartridge adapter when the disk holder is inserted into or removed from the disk cartridge adapter.

[Opening / Closing Member] Next, the opening / closing member (lid) 6 for opening and closing the opening 16 will be described in detail. First, reference is made to FIGS. The opening / closing member 6 is rotatably held by a rotating shaft 31 fitted into the rotating hole 18 of the case main body 3. On the opposite side of the rotation shaft 31, a contact portion 32 that contacts the lock portion 19 of the case body 3 is formed. A pressing portion 33 is provided on the tip side of the contact portion 32.

The contact portion 32 can be elastically deformed. By pressing the pressing portion 33, the lock between the contact portion 32 of the opening / closing member 6 and the lock portion 19 of the case body 3 can be released. .

As shown most clearly in FIG. 3, a recess for receiving the positioning pin 41 is formed in the center of the opening / closing member 6, and the positioning pin 41 is movably disposed in this recess. The positioning pin 41 is formed of, for example, a material such as plastic, and the size of the positioning pin 41 is, for example, 9 mm in length and 3 mm in diameter. An elastic member 42 is provided at a root portion of the positioning pin 41 and urges the positioning pin 41 in a protruding direction. In the present embodiment, a compression coil spring is used as the elastic member 42.

After the positioning pins 41 and the elastic members 42 are placed in the recesses of the opening / closing member 6, the auxiliary plate 43 is assembled to the opening / closing member 6. The auxiliary plate 43 has a plurality of locking claws 4.
4 are formed, and each locking claw 44 passes through the corresponding locking opening 34 of the opening / closing member 6 while being elastically deformed. The auxiliary plate 43 is fixed to the opening / closing member 6 at the position where the elastic deformation is released. The positioning pin 41 is restrained by the auxiliary plate 43 so as not to come off from the opening / closing member 6, but can move back and forth along the extension direction (projection direction) of the positioning pin 41. Normally, the tip of the positioning pin 41 is in a state of being advanced in a direction protruding from the opening / closing member 6 by the force of the elastic member 42, but some force is applied to the positioning pin 41.

The extending disk 1 is guided by moving members 7 arranged on the left and right sides of the disk cartridge adapter 2, passes between the two moving members 7, and enters the inside of the case body 3. In the process, the tip of the disk holder 75 comes into contact with the grip 63 formed on the rotating plate 60 of the moving member 7. When the disc holder 75 is further pushed in, the turning plate 60 turns in the direction outside the disc cartridge adapter 2 against the pressing member 64, and the disc holder 75 can pass therethrough. Eventually, the grip 63 comes into contact with the notch 80 of the disk holder 75. Then, the rotating plate 60 is pressed by the pressing member 64.
As a result, the disk holder 75 and the disk 1 return to their original postures, so that the disk holder 75 and the disk 1 do not drop from the case body 3 (gripping state).

Next, when the opening / closing member 6 is turned around the turning hole of the case main body 3, the end face of the opening / closing member 6 and the end face on the rear end side of the disk holder 75 abut. Further, when the opening / closing member 6 is rotated, the opening / closing member 6 is opposed to the elastic member 55, and the disk holder 75, the disk 1, and the moving member 7
Simultaneously into the case body 3. At this time, the positioning pin 41 provided on the opening / closing member 6 comes into contact with the end face on the rear end side of the disk holder 75. The positioning pin 41 moves inside the opening / closing member 6 from a state protruding from the opening / closing member 6 against the elastic member 42.

After the contact portion 32 of the opening / closing member 6 comes into contact with the lock portion 19 of the case body 3, the contact portion 32 passes through the lock portion 19 while being elastically deformed. When the opening / closing member 6 is attached to the case body 3 without any gap, the contact portion 32
Releases the elastic deformation, and the opening / closing member 6 is
Is fixed to the case body 3. FIG. 6 shows a state in which the fixing is performed.

When the disk holder 75 and the disk 1 are inserted into the case main body 3 as described above, the tip of the disk support portion 77 of the disk holder 75 is held by the locking wall 13 of the case main body 3 with respect to the case main body 3. The position is determined. At this time, the disc holder 75 is positioned by the pressing member 8 with no gap with respect to the inner surface of the lower case main body 3b. Further, the disk 1 also has a predetermined gap, and the partition 12 of the case body and the disk holder 7
5 is positioned by the disk support portion 77 of FIG.

In this embodiment, as described above,
A recess 20 is provided in the approximate center of the rear ends of the upper and lower case
Are formed (FIG. 2). FIG. 10 shows a cross section of a portion where the concave portion 20 is formed. FIG. 10 shows a state where the disk holder 75 is completely inserted into the case body 3. As can be seen from FIG. 10, the recess 20 provided in the upper case body 3a and the recess 20 provided in the lower case body 3b have different sizes. More specifically, the lateral size of the recess 20 provided in the upper case body 3a in this embodiment is designed to be smaller than the lateral size of the recess 20 provided in the lower case body 3b. For example, the lateral size of the recess 20 provided in the upper case body 3a is 23 mm, and the lateral size of the recess 20 provided in the lower case body 3b is 33 mm. As a result, the cross-sectional shape of the opening shown in FIG. 10 is vertically asymmetric. On the other hand, the cross-sectional shape of the grip portion 81 of the disk holder 75 is designed to match the cross-sectional shape of the opening, and is vertically asymmetric. As a result, when trying to insert the disc holder 75 upside down into the opening of the case body 3, the end face of the upper case body 3 a in which the concave portion 20 having the smaller size in the lateral direction is formed and the grip portion 81. , The disk holder 75 cannot be inserted any further.

As described above, in the present embodiment, the cross-sectional shape of the opening is asymmetric, and the shape of the grip portion 81 of the disk holder 75 is designed so as to match with this.
This prevents incorrect insertion of the disk holder 75 upside down.

Next, the operation of inserting the disk 1 into the disk cartridge adapter 2 will be described.

First, as shown in FIG. 7, the disk 1 is inserted into the opening 16 of the disk cartridge adapter 2 and stored in the case body 3. Next, when the opening / closing member 6 is rotated about the rotation hole of the case main body 3, the contact portion 32 of the opening / closing member 6 comes into contact with the lock portion 19 of the case main body 3, and the contact portion 32 is elastically deformed.
