DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge containing a disk-shaped recording medium and a disk-shaped recording medium built in the disk cartridge which can be recorded / reproduced by a disk cartridge drive apparatus having a larger size. To a cartridge adapter.

[0002]

2. Description of the Related Art With the rapid development of computer technology, disk-shaped recording media have been widely used as means for recording, reproducing and erasing various information. There are a plurality of standards for disc-shaped recording media having different recording densities, sizes, recording / reproducing methods, etc., and there are also a plurality of drive devices for recording / reproducing / erasing the disc-shaped recording media of each standard. ing.

[0003] Under such circumstances, it is convenient for a user if a single drive can record, reproduce, and erase a disk-shaped recording medium of a plurality of standards, and various methods have been proposed.

As a method of recording / reproducing / erasing a plurality of disc-shaped recording media having different sizes with a single drive device, for example, a user inserts a naked disc-shaped recording media into an adapter and inserts the same into a drive device. A setting method has been proposed, and a compact disk (C
D) and a CD single having a diameter of 8 cm have been partially put to practical use.

[0005] In addition, disc-shaped recording media of different sizes contained in a cartridge are recorded and recorded by one drive device.
As a method of reproducing / erasing, for example, as shown in FIG. 51, a small-sized disk cartridge 1901 is housed in a cartridge adapter 1911 having the same size and outer shape as a large-sized disk cartridge, and a drive for a large-sized disk cartridge is mounted. Recorded by device 1921
A method of reproducing / erasing is being studied (for example, Japanese Patent Application Laid-Open No. 2-121174). In FIG. 51, 1912
Denotes a head opening window of the cartridge adapter 1911;
Reference numeral 13 denotes shutters, which are formed in the same shape and dimensions as a large-size disk cartridge.
Reference numeral 1902 denotes a small-sized disk cartridge 19.
01 is a head opening window, and 1903 is a shutter. 1
Reference numeral 914 denotes an insertion unit for inserting a small-sized disk cartridge 1901, and 1924 denotes an insertion unit for inserting a large-sized disk cartridge.

[0006]

However, a method in which a user inserts a disk-shaped recording medium in a naked state into an adapter and sets it in a drive device is a method in which a user attaches dirt or a scratch to the disk-shaped recording medium. It is easy to use and is not suitable for applications requiring high reliability and durability.

As shown in FIG. 51, a small-sized disk cartridge is housed in a cartridge adapter having the same dimensions and outer shape as a large-sized disk cartridge, and recording / reproducing is performed by a large-sized disk cartridge drive device. -The erasing method has the following problems, for example. That is, the shape and dimensions of the head opening window and shutter provided in the disk cartridge and the opening / closing mechanism thereof are different between a small-sized disk cartridge and a large-sized disk cartridge. Accordingly, the head of the drive device is mounted on the cartridge adapter 1911 and the exterior member and the shutter 1 around the head opening window 1902 of the small-sized disk cartridge 1901 are stored.
Problems such as contact with the 903 and the mechanism for opening and closing the shutter become complicated, and in the end, it is difficult to record / reproduce / erase disk cartridges of different sizes without any problem with such an adapter. In some cases, it is necessary to review the design of the drive device itself in consideration of such use.

Accordingly, the present invention solves the above-mentioned conventional problems, and records, reproduces, and erases information on a disk-shaped recording medium stored in a disk cartridge by using an adapter to increase the size. With a drive device for a disk cartridge of a size, the disk drive can be attached to the adapter without directly touching the disk-shaped recording medium, without requiring a major design change on the drive side, and An object of the present invention is to provide a disk cartridge and an adapter which ensure the reliability of information and the durability of a disk.

With the disk cartridge having the above-described structure, it is possible to record / reproduce / delete information by mounting the disk cartridge as it is in a drive device for a disk cartridge having compatibility with the disk cartridge. Through the adapter, information can be recorded / reproduced / erased even with a disk cartridge drive device of a larger size. Moreover, since a large design change is not required on the side of the drive device for a large size, and since the user does not directly touch the disk-shaped recording medium, the reliability of information and the durability of the disk are ensured.

Further, the adapter of the present invention has an insertion portion through which a disk cartridge can be taken in and out, and when the disk cartridge is inserted to a predetermined position of the insertion portion, the opening / closing lid of the disk cartridge is fixedly held to the case body. A first unlocking means for unlocking the first locking means, the opening / closing lid having the first locking means unlocked is latched, and the opening / closing is performed after the case main body is removed from the insertion portion. Open / close lid holding means for holding a lid at a predetermined position of the insertion portion, and opening / closing lid holding release means for releasing the holding of the open / close lid and allowing the open / close lid to be taken out of the insertion portion, I do.

By adopting the adapter having the above configuration,
Recording, playback and erasing of information on small-sized discs
The present invention can be realized by a large-sized disk cartridge drive device compatible with the adapter.
Moreover, since a large design change is not required on the side of the drive device for a large size, and since the user does not directly touch the disk-shaped recording medium, the reliability of information and the durability of the disk are ensured.

By doing so, the engagement between the first lock projection 203 and the lock hole 105 can be released.

As described above, the release of the first lock means
By making it possible other than when the disk is inserted into an adapter to be described later, the user can take out the built-in disk as needed and perform inspection, cleaning, or replacement of the disk.

As shown in FIG. 3, the disk cartridge according to the present embodiment
It is preferable to have a second lock means for restricting the movement of the opening / closing lid 201 in the pulling-out direction at a position where the disk 10 can be taken out from the disc 101 and taken out.

As described above, in a disk cartridge in which the user can release the first locking means, pull out the opening / closing lid 201, and take out the built-in disk 10, the opening / closing lid 201 or the disk 10 It is desirable to equip it with a safety mechanism that does not drop The second locking means functions effectively for this.

In the case of the disk cartridge according to the present embodiment, the second locking means includes lock holes formed near the opening 102 of the opposed inner wall 104 forming a part of the disk storage portion 103 of the case body. 105,
A second lock projection formed at the tip of the disc holding member 202 of the opening / closing lid 201 so that the opening / closing lid 201 is fitted to the lock hole 105 at a position where the opening / closing lid 201 is pulled out until the built-in disk 10 can be taken out. 207.

The locking of the opening / closing lid 201 in the pull-out direction by the second locking means is performed as follows. FIG.
When the opening / closing lid 201 is pulled out from the case main body 101 from the state shown in FIG. The disc holding member 202 is pulled out in a state of being elastically deformed so as to come into contact with each other, but is formed at the distal end of the disc holding member 202 after the outwardly curved portion 202a of the disc holding member 202 comes out of the case body. Second lock projection 20
7 is pulled out while abutting on the inner wall 104. And
When the second lock projection 207 reaches the lock hole 105, the disk holding member 202 elastically recovers, and
The lock projection 207 is fitted into the lock hole 105 to restrict the subsequent pulling out of the opening / closing lid 201 (FIG. 3). Therefore, the user does not vigorously pull out the opening / closing lid 201, and does not accidentally drop the opening / closing lid 201 or the disk 10.

On the other hand, the release of the second lock means is performed as follows.

As shown in FIG. 3, in a state where the second locking means is functioning, the two disk holding members 202 are gripped so as to approach from the outside to the inside, and the two disk holding members 202 are elastically deformed. Thus, the engagement between the second lock projection 207 and the lock hole 105 can be released.

The second lock projection 207 is inclined so that the tip thereof forms an acute angle as shown in the figure. Therefore, when the opening / closing lid 201 is inserted into the opening 102 of the case body, or The second lock projection 2 as shown in FIG.
When the opening / closing lid 201 is further inserted from the state where the lock hole 105 and the lock hole 105 are fitted together, the two disk holding members 202 are easily elastically deformed in the direction approaching each other due to the inclination, and the insertion of the opening / closing lid 201 is performed. There is nothing to hinder.

Further, in the disk cartridge of the present embodiment, the lock hole that fits into the first lock protrusion 203 and the lock hole that fits into the second lock protrusion 207 are:
A common lock hole 105 was used. This makes it possible to simplify the structure. Of course, it is not a problem to provide each of the holes separately.

The disk cartridge of the present embodiment is
Due to the function of the second locking means, the opening / closing lid 2
It is preferable that the opening / closing lid 201 can be elastically deformed in a direction substantially perpendicular to the disk surface in a state in which the movement in the pull-out direction of 01 is restricted. FIG. 4 is a schematic view showing a state in which the movement of the opening / closing lid in the pulling-out direction of the disk cartridge according to the present embodiment having such a configuration is restricted by the second locking means, and FIG. , (B)
Is a side view thereof. As shown in FIG. 4B, the portion of the disk holding member 202 can be elastically deformed in a direction substantially perpendicular to the surface of the disk 10. By doing so, the user can easily take out the disk 10.

In the disk cartridge according to the present embodiment, the third locking means for fixing the opening / closing lid 201 to the case main body 101 at a position where the opening / closing lid 201 is completely stored in the case main body 101 and the opening 102 is closed. It is preferable to have In addition, unlike the first locking means, the fixed holding state by the third locking means can be released by applying an external force, but the release is irreversible, that is, once released, the state returns to the original state. It is preferable that it cannot be performed.

Unlike a disk which is assumed to be handled in a bare state, it is not originally desirable that a disk housed in a disk cartridge be taken out by a user in order to avoid the attachment of scratches and dust. . The disk cartridge of the present embodiment is
A mechanism for releasing the lock means is provided, and the release is possible only by a predetermined operation of the user. However, even if the user does not intend to remove the disk, it is not unexpected that the first locking means is suddenly released while handling the disk cartridge. The third locking means provides a means for preventing such unintended release of the first locking means. Accordingly, the release of the third lock means must not be a structure that is released unintentionally in a normal use state, and the release can be achieved only by applying a predetermined external force. It is.

Further, when the third locking means is released, it is preferable that the fact can be easily confirmed. A disk cartridge confirmed to be unlocked means that the built-in disk has been exposed to the outside world by the user at least once, and the user locks the disk in terms of information reliability and the like. It can easily be inferred that it may be inferior to a disc cartridge that has not been released. The release of the third lock means here does not include the release when the opening / closing lid is attached to the adapter described later. According to the present invention, when attaching the opening / closing lid to the adapter, the user can perform the operation without touching the disk at all. Therefore, in this case, the reliability of the information recorded on the disk due to the release of the third lock means is negligible.

An example of the structure of the third lock means will be described with reference to FIGS. FIG. 5 is an enlarged partial cross-sectional perspective view of the third locking means of the opening / closing lid according to the present embodiment, and FIG. 6 is a perspective view of the third locking means of the disk cartridge according to the present embodiment. It is the partial cross-sectional perspective view which expanded the part.

As shown in FIGS. 5 and 6A, the third locking means according to the present embodiment is formed near the opening 102 of the case main body 101 so as to penetrate from front to back. 3 and the opening / closing lid 201 of the case body 1
And a third lock projection 209 formed on the opening / closing lid 201 so as to be fitted into the third lock hole 106 at a position where the opening 102 is completely closed and accommodated.
More specifically, a lock key 2
08 is formed integrally with the opening / closing lid 201 via the connecting portion 210 and is formed so as to protrude from the front and back of the opening / closing lid 201, and the projecting portion of the lock key 208 from the opening / closing lid 201 is the third lock. A projection 209 is formed. The connecting portion 210 includes a substantially central portion of each of the four surfaces around the lock key 208 and the opening / closing lid 2 surrounding the lock key 208.
08 (see FIG. 20 described later).

The release of the third lock means is performed as follows.

In the state shown in FIG.
When a predetermined external force (arrow F in FIG. 5) is applied so as to push in the third lock projection 209 in the connector 6, the connecting portion 210 is broken, and as shown in FIG. The lock key 208 is removed to the outside through the lock hole 106, and the third lock means is released. In FIG. 6B, reference numeral 210 ′ denotes a fractured surface of the connection part 210. Further, by releasing the first locking means, the opening / closing lid 201 can be pulled out of the case main body 101 as shown in FIG.

Further, when the third locking means is released as described above, the lock key 208 is ejected to the outside, so that the state before the release cannot be restored. Further, when the opening / closing lid 201 is housed in the case main body 101, the third lock projection does not exist in the third lock hole 106, and the other side can be seen through the third lock hole 106. Thus, the user can easily recognize the fact that the third locking means has been released in the past.

The release of the third lock projection can be performed in the recess 213 formed near the third lock means without using the irreversible means of discharging the lock key 208 as described above. The insertion can be performed reversibly by fitting the convex portion (third unlocking projection 607) of the third unlocking means of the adapter of the present invention.

After the opening / closing lid 201 is removed from the case main body 101 as described above, when the opening / closing lid 201 is to be inserted again into the disk storage portion 103 of the case main body 101, the opening / closing lid 201 is correctly fitted to the case main body 101. It is preferable to provide an erroneous insertion preventing means so that the device is inserted in the correct direction. The erroneous insertion preventing means is provided in the case body 10.
If the user tries to insert the opening / closing lid 201 in the wrong direction into the opening 102, the insertion cannot be performed at all, or even if the opening / closing lid 201 is inserted to a certain extent, the opening / closing lid 201 is not completely inserted into the case body 101. However, it is preferable to make the structure such that it is easy to recognize that the insertion is made in the wrong direction.

As shown in FIG. 2, the means for preventing erroneous insertion of the case main body and the opening / closing lid of the disc cartridge according to the present embodiment includes notches 107, 108 provided on the end face of the opening 102 of the case main body 101. , And a fitting member composed of erroneous insertion preventing protrusions 211 and 212 provided at predetermined positions of the opening / closing lid 201.

When the opening / closing lid 201 is inserted into the case main body 101 in the correct direction, the notch 107 and the erroneous insertion preventing projection 211 and the notch 108 and the erroneous insertion preventing projection 2
12 are fitted with each other, and as shown in FIG.
01 is completely housed in the case body 101 and the opening / closing lid 20
1 closes the opening 102.

On the other hand, the case body 1 is
01 is inserted upside down, it can be inserted to some extent, but notch 107 and notch 1
08, the opening / closing lid 201 cannot be completely housed in the case main body 101 as shown in FIG. This allows the user to easily know that the insertion has been made in the opposite direction.

The above is an example in which the fitting member is formed in an asymmetrical shape with respect to the center line in the insertion direction of the case body of the opening / closing lid into the disk storage portion, but the erroneous insertion preventing means is not limited to this. The fitting member may be formed at an asymmetric position with respect to the center line in the insertion direction.

The disk cartridge of the present invention is used by being inserted into an adapter described later. At this time, it is preferable to provide a means for preventing erroneous insertion of the disk cartridge into the adapter so that the disk cartridge is inserted in the correct direction. Such an erroneous insertion prevention means cannot be inserted at all when an attempt is made to insert a disk cartridge in an incorrect direction in an adapter, or an erroneous insertion prevention means cannot be inserted to a predetermined position even if it can be inserted to a certain extent. It is preferable to make the structure so that it can be easily recognized that it is inserted in the direction.

As shown in FIG. 1, the means for preventing the disk cartridge from being erroneously inserted into the adapter according to the present embodiment is provided on the front end face in the insertion direction of the disk cartridge into the adapter at a position asymmetric with respect to the center line in the insertion direction. It is composed of a formed concave portion 213 and a convex portion (an erroneous insertion prevention protrusion 607) formed in an insertion portion of an adapter fitted to the concave portion 213.

When the disc cartridge 100 is inserted in the correct direction into an adapter described later, the protrusion formed in the insertion portion of the adapter fits into the recess 213 formed on the front end face of the disc cartridge 100 in the insertion direction. The cartridge 100 can be reliably inserted to a predetermined position in the adapter.

On the other hand, if the user tries to insert the disc cartridge 100 upside down into the adapter, the disc cartridge 100 can be inserted up to a certain extent, but the protrusion formed in the insertion portion of the adapter causes the disc cartridge 100 to be inserted in the insertion direction. It contacts the front end face and cannot be inserted any further.
Thereby, the user can easily know that the insertion has been made in the opposite direction.

The above is an example in which the recess is formed at an asymmetric position with respect to the center line in the insertion direction of the disk cartridge. However, the means for preventing erroneous insertion is not limited to this. It may be formed in any shape.

In a state where the opening / closing lid 201 and the disk 10 are mounted on the insertion portion of the adapter by a method described later, and the door of the adapter is not closed (see FIG. 19), the disk 10 is opened at the opening of the insertion portion of the adapter. In order to prevent the disc holding member 202 from falling out of
Is preferably smaller than the disk diameter.

The opening / closing lid 201 is formed with a hook portion 214 which engages with the opening / closing lid holding means of the adapter described later.

The disc cartridge according to the second embodiment is different from the disc cartridge according to the first embodiment in that the former is designed on the assumption that the user takes out the built-in disc by himself. Whereas
The latter is that such a case is not assumed. In other words, the disk cartridge according to the second embodiment eliminates the possibility that the user removes the built-in disk by himself, thereby minimizing the possibility of scratches or foreign matter adhering to the disk, and removing recorded information. It aims to achieve high reliability and durability of the disk.

Therefore, in the disk cartridge according to the first embodiment, the components provided on the assumption that the user takes out the built-in disk by himself are deleted in the disk cartridge according to the second embodiment. In other respects, it has the same configuration as the disk cartridge according to the first embodiment.

With respect to the disk cartridge according to the first embodiment, the components deleted in the disk cartridge according to the second embodiment are the components relating to the release of the first locking means, and the second locking means. And the third lock means. Hereinafter, these will be described in order.

The disk cartridge according to the second embodiment does not include some of the components related to the release of the first locking means included in the disk cartridge according to the first embodiment. That is, the first portion of the hinge 204
The first unlocking knob (the first unlocking knob 2 of the first embodiment) elastically displaced integrally with the lock projection 203 of the first embodiment.
06). In the disk cartridge shown in the second embodiment, since the lock hole 105 is a through hole communicating with the outside of the case main body, a pointed rod is inserted into the through hole from the outside of the case main body in an emergency. The engagement between the first lock projection 203 and the lock hole 105 can be released.

Further, the disk cartridge according to the second embodiment does not have the components related to the second locking means of the disk cartridge according to the first embodiment.

Thus, if the adapter 500 is mounted on a disk cartridge drive device that is externally compatible with the adapter, it becomes possible to reproduce information recorded on the disk in the adapter, or to record or erase information.

The above structure and function will be described below in order.

A description will be given of the first unlocking means of the adapter according to the third embodiment of the present invention.

The first unlocking means of the present invention is shown in FIG.
As shown in FIG. 5, a pair of first
The lock release bar 606 of FIG. The first unlocking bar 606 is installed at a position where it comes into contact with a pair of first unlocking claws 205 (see FIG. 3) formed on the end face of the opening / closing lid 201 when the disk cartridge is inserted into the insertion portion 602. Have been. Also, the first unlocking bar 606
The tip of is inclined at an acute angle. Therefore, the acute-angled inclined surface at the distal end of the first unlocking bar 606 contacts the acute-angled inclined surface at the distal end of the first unlocking claw 205, and the pair of first unlocking claws 205 is moved. An external force is generated so as to be displaced inward, and the hinge 204 is elastically deformed (see FIG. 17).
As a result, the first lock projection 203 is displaced integrally, and the engagement between the first lock projection 203 and the lock hole 105 is released.

The first unlocking means of the present invention unlocks the disk cartridge having the first locking means as in the first and second embodiments and separates the opening / closing lid from the case body. It is an essential element to perform.

Next, the third unlocking means of the adapter according to the third embodiment of the present invention will be described.

The third unlocking means is necessary for unlocking the disk cartridge having the third locking means according to the first embodiment of the present invention and separating the opening / closing lid from the case body. Element. Further, the release of the third lock means by the third lock release means needs to be reversible, unlike the irreversible means of discharging the lock key 208 described above.

The third unlocking means of the present invention is shown in FIG.
As shown in FIG. 7, the third lock release projection 607 is formed on the contact wall 605.

FIG. 20 is a partially enlarged view for explaining the operation state of the third unlocking means of the present invention, and FIG.
Is a partial cross-sectional view taken along a plane perpendicular to the disk surface and passing through the center of the third unlocking projection 607, (b) is a cross-sectional view taken along line II of FIG. ) Is (a)
FIG. 2 is a sectional view taken along line II-II in the direction of the arrow.

The third lock release projection 607 is
05 and the disk cartridge is inserted into the insertion portion 602.
Is inserted into the recess 213 formed near the third locking means on the end face of the opening / closing lid 201 when inserted. In addition, the third unlocking projection 607
As shown in FIG. 20 (a), a slope is formed so that the tip is thinner than the root. More specifically, the width d1 of the tip in the direction perpendicular to the disk surface is equal to the case body 101. The width d2 of the root portion is smaller than the interval between the inner walls, and is larger than the length of the lock key 208. Therefore, when the disk cartridge is inserted into the insertion portion 602, the tip of the third unlocking projection 607 is inserted into the concave portion 213, and when the disk cartridge is further pushed in, the third lock release projection 607 becomes third.
Is elastically deformed so that the root of the lock release projection 607 pushes the inner wall interval of the case main body 101 of the disk cartridge. At this time, the concave portion 21 of the case body 101

Is released, and the third locking means is released (see FIGS. 20A and 20C).

As described above, the release of the third lock means by the third lock release means utilizes the elastic deformation of the case main body 101.
01 does not involve the breaking of the connecting part 210,
It is reversible.

Next, the means for preventing erroneous insertion of a disk cartridge according to Embodiment 3 of the present invention will be described.

In the adapter of the present invention, if the user attempts to insert the disk cartridge in the wrong direction, it cannot be inserted at all, or even if it can be inserted to a certain extent, it cannot be inserted to a predetermined position. Therefore, it is preferable to provide a means for preventing erroneous insertion of the disc cartridge so that the user can easily recognize that the disc cartridge is inserted in the wrong direction.

The means for preventing the disk cartridge from being erroneously inserted into the adapter according to the present embodiment is formed on the contact wall 605 at an asymmetrical position with respect to the center line of the disk cartridge in the direction of insertion into the adapter. It comprises an insertion prevention protrusion 607 and a concave portion 213 formed on the front end face in the insertion direction of the disk cartridge so that the erroneous insertion prevention protrusion 607 is fitted when the disk cartridge is inserted in the correct direction.

In this embodiment, the erroneous insertion preventing projection 607 is used.
Functions as the above-described third unlocking projection 607, but may be provided separately.

When the disc cartridge is inserted into the insertion section 602 in the correct direction, the erroneous insertion prevention projection 607 formed in the insertion section of the adapter fits into the recess 213 formed on the front end face in the insertion direction of the disc cartridge. The disk cartridge can be reliably inserted into the adapter to a predetermined position (FIG. 16).

On the other hand, if the user attempts to insert the disk cartridge upside down with respect to the adapter, the disk cartridge can be inserted to some extent, but the erroneous insertion prevention protrusion 607 formed in the insertion portion of the adapter causes the disk cartridge to be inserted. Abuts the front end face in the direction and cannot be inserted any further. Thereby, the user can easily know that the insertion has been made in the opposite direction.

In the above example, the erroneous insertion preventing projection is formed at an asymmetrical position with respect to the center line of the disk cartridge in the inserting direction. However, the erroneous insertion preventing means is not limited to this. The erroneous insertion prevention projection may be formed in an asymmetric shape.

Next, the open / close lid holding means of the adapter according to the third embodiment of the present invention will be described.

The opening / closing lid holding means of the present invention locks the opening / closing lid 201, which has been disengaged from the case main body 101 by the first unlocking means and the third unlocking means, into the insertion portion 602 of the adapter. In addition, it functions to hold the case main body 101 at a predetermined position in the insertion portion 602 even after the case main body 101 is pulled out.

The open / close lid holding means has a holding hook 702 as shown in FIGS. 13 and 14, and is held by a lower case 601 via a guide pin 608 so as to be movable in the left-right direction of FIG. Opening / closing lid holding plate 701 and opening / closing lid holding plate 7
And a tension spring 703 that urges the elastic member 01 in one direction (rightward in FIG. 13) with an elastic force. When the disc cartridge is inserted into the insertion portion 602, the holding hook 702
It is installed at a position corresponding to a hook 214 (see FIG. 3) formed on the end face of the opening / closing lid 201. And FIG.
As shown in the figure, the tip is inclined so as to form an acute angle. Therefore, the disc cartridge is inserted into the insertion portion 60.
When the disc cartridge is further inserted, the tip of the holding hook 702 comes into contact with the end of the hook 214 of the opening / closing lid. The plate 701 moves to the left in FIG. 13 and is then pulled back by the tension spring 703 so that the holding hook 702 and the hook 214 are engaged. At the same time, since the first locking means and the third locking means are both released, even if the case main body 101 is subsequently pulled out from the insertion portion 602, the opening / closing lid 201 remains in the insertion portion 602.
(FIG. 17).

It is desirable that the open / close lid 201 hooked by the open / close lid holding plate 701 is stably held at a predetermined position in the insertion portion 602. Opening / closing lid 201 is inserted portion 60
If the disk is freely movable within the disk drive 2, the lid 201 may come into contact with the disk when the disk is rotating with the adapter mounted on the drive device. Further, in order to ensure that the second unlocking means described later functions, it is desirable that the relative position between the opening / closing lid 201 and the lower case 601 is always kept constant. To achieve this,
The adapter according to the third embodiment has an open / close lid stable holding unit.

As shown in FIGS. 13 and 14, the opening / closing lid stable holding means is a pressing / rotating member 711 held on the lower case 601 so as to be rotatable around the guide pin 608.
And a tension spring 713 that urges the pressing and rotating member 711 in one direction by an elastic force, and two sets of these are installed.
The pressing and rotating member 711 has a pressing portion 712 at one end thereof, and when the disc cartridge is inserted into the insertion portion 602, the pressing portion 712 abuts on the end face of the opening / closing lid, and the opening / closing lid is urged by a tension elastic force of a tension spring 713. 201 is the insertion part 6
02 in the direction of discharging (upward on the paper surface of FIG. 13). The opening / closing lid 201 is stably held at a predetermined position in the insertion portion 602 by the pressing force and the opening / closing lid holding means (see FIGS. 17 to 19).

Although the opening / closing lid stable holding means will be described later in detail, when the opening / closing lid 201 described later is taken out together with the case body, it is clear that the fact that the opening / closing lid holding means has been released is clearly understood. And has the effect of facilitating its removal.

Next, the second unlocking means of the adapter according to the third embodiment of the present invention will be described.

The second unlocking means prevents the second locking means from functioning in the disk cartridge according to the first embodiment of the present invention having the second locking means, and moves the opening / closing lid from the case body. It is necessary for complete separation.

The second unlocking means of the present invention is shown in FIG.

And a second unlocking projection 609 formed so as to protrude toward the insertion portion 602 at the tip end of the second lock release projection 609.

The second unlocking projection 609 is
When the disc cartridge is inserted, the second unlocking projection 609 abuts against the side wall of the case main body 101 of the disc cartridge, and the elastic bar 610 is elastically deformed so as to escape from the insertion portion 602. I do. Then, as shown in FIG. 16, the second unlocking projection 609 is formed on the opening / closing lid 201 via the side wall of the case main body 101 in a state where the opening / closing lid 201 is stably held by the opening / closing lid holding means. The second lock projection 207 is formed at a position facing the second lock projection 207.

Thereafter, when the case main body 101 is to be pulled out from the insertion portion 602 with the opening / closing lid 201 held by the opening / closing lid holding means, the second unlocking is performed by the lock hole 105 opened in the side wall surface of the case main body 101. The protrusion 609 is fitted (FIG. 17). At the same time, the second lock projection 207 formed on the opening / closing lid 201 also tries to fit into the lock hole 105, but the elastic restoring force of the elastic bar 610 is stronger than the elastic restoring force of the disk holding member 202 of the opening / closing lid. Therefore, the second lock projection 207 is pushed by the second lock release projection 609 so that the lock hole 105 is locked.
Can not fit into Further, since the second unlocking projection 609 has inclined surfaces formed on both sides in the traveling direction of the lock hole 105 as shown in the figure, if the case main body 101 is to be further pulled out of the insertion portion 602 from this state, The second lock release projection 6 is provided at the end of the lock hole 105.
The elastic bar 610 is elastically deformed, and the second lock release projection 609 moves so as to escape to the outside of the insertion portion 602. Therefore, the case main body 101 can be continuously removed from the insertion portion 602 as it is.

As described above, the second unlocking means is the second unlocking means.
To prevent the locking means from functioning.

Next, the door 510 provided on the adapter according to Embodiment 3 of the present invention will be described.

After the disk 10 is housed in the adapter 500 as described above and the case main body 101 is removed, the opening of the insertion portion 602 is prevented in order to prevent intrusion of dust and unexpected fall of the built-in disk. Close door 51
It is preferable to provide 0.

In this case, after the user inserts the disk cartridge into the insertion portion 602, the case body 10
Even if one forgets to extract 1, ie, FIG.
If the door 510 can be closed even in the state shown in FIG. In this case, there is a possibility that the drive device, the adapter, the case body, the disk, etc. may be damaged by the collision of the head of the drive device or the disk drive device with the case body 101 or the shutter 181 left in the insertion portion.

Therefore, the case main body 101 is inserted into the insertion portion 602.
Is inserted, it is preferable that the door 510 should not be closed. Further, when the door 510 is completely closed, the external shape of the adapter 500 is compatible with the corresponding disc cartridge.
It is more preferable that the drive device is not mounted when the door 510 is open.

As shown in FIG. 14, the door 510 according to the present embodiment rotates about a rotation shaft 513 supported by an upper case 501 (not shown in FIG. 14) and a lower case 601. A door hook 511 that is movably provided and is lockable to the upper case 501 (not shown in FIG. 14) and the lower case 601 when the door 510 is completely closed.

On the other hand, the case main body 101 is inserted into the insertion portion 602.
When the user tries to close the door 510 while leaving the case body, as shown in FIG.
The door 510 cannot be closed by contacting one side surface of the door 01. Therefore, the user can know that the user has forgotten to remove the case main body 101. In addition, if the door 510 is not completely closed, the compatibility of the external shape with the corresponding disk cartridge is not ensured, so that some drive devices cannot be mounted in this state. This eliminates the risk of accidentally damaging the drive device, the adapter, the case body, the disk, and the like.

Further, the adapter according to the present invention has
It is preferable that the internal state, in particular, at least a part of the disc, can be confirmed from the outside. Thereby, the presence or absence of a disk in the insertion portion 602, the type of the disk, and the like can be confirmed. As such a checking means, a checking window may be provided at an appropriate position of the upper case 501 and / or the lower case 601 or a part or all of the checking window may be made of a transparent member.

[0146] Therefore, the danger of the user erroneously activating the opening / closing lid holding / releasing means when the case body is not inserted into the insertion portion 602 is eliminated.

When the case body 101 is inserted into the insertion portion 602, as shown in FIG. 16, the case body contact portion 757 formed on one end surface of the disc regulating member 751a is , The disc regulating member 751a rotates clockwise about the support shaft 613 as shown in FIG. As a result, the lock projection 756 of the disc regulating member 751a escapes from the notch 734 of the opening / closing lid holding / releasing bar 731. Therefore, the opening / closing lid holding / unlocking means does not work, and the user can operate the operating lever of the opening / closing lid holding / releasing bar 731. By operating 732, the disk cartridge can be taken out.

Next, the disc regulating means of the adapter according to the third embodiment of the present invention will be described.

The disc restricting means of the present invention operates in a state where the disc 10 is mounted on the insertion portion 602 of the adapter (FIG. 1).
8), when the case main body 101 is inserted into the insertion portion 602, the position of the disk is regulated in the thickness direction so that the disk 10 is surely inserted into the opening 102 of the case main body. It is preferable to equip it for convenience.

The disc restricting means of the present embodiment is similar to that of FIG.
3, the insertion portion 6 of the lower case 601 as shown in FIG.
02, two support shafts 61 formed at both ends near the opening
The disc restricting member 75 which is rotatably held about the respective pivots 3 and 613 and has a first restricting portion 752 formed at one end thereof so as to grip the disc from both sides.
1a, 751b, fixing pins 614, 614 fixed to the lower case 601, and restricting the rotation of the disc regulating members 751a, 751b by contacting a part of the disc regulating members 751a, 751b, and the disc regulating member 75.
The torsion coil springs 760 and 760 are locked by the spring locking portions 755 of the first and the first case 751b and the lower case 602, and press and fix the disc regulating members 751a and 751b to the fixing pins 614 and 614 by elastic force. The disc regulating means are provided at both ends near the opening of the insertion portion 602, but in the present description, members having the same function are denoted by the same reference numerals without distinction between them.

The operation of the disk regulating means having the above configuration will be described.

As shown in FIGS. 18, 23 and 24,
The opening / closing lid 201 and the disc 1 are inserted into the insertion portion 602 of the adapter.
0, the disc regulating members 751a,
751b is pressed and fixed to the fixing pin 614 by the torsion coil spring 760. At this time, the first regulating portions 752 of the disc regulating members 751a and 751b hold the end of the disc 10 from both sides, and regulate the position of the disc in the thickness direction. Therefore, when the case body 101 is inserted into the insertion portion 602 from this state, the disc 10 can be reliably inserted into the opening 102 of the case body.

Incidentally, the end of the disk 10 is
01 after being inserted into the opening 102 of the case 10
When the disc cartridge 1 is inserted into the insertion portion 602, the case body contact portions 757 formed on one end surfaces of the disc regulating members 751a and 751b come into contact with the side surface of the case body 101, and the disc regulating members 751a and 751b are pivoted. As shown in FIG. 17, the disc regulating member 751
“a” rotates clockwise, and the disc regulating member 751 b rotates counterclockwise, and escapes from the insertion portion 602.

In the disk restricting means having the above structure, when the disk is housed in the adapter and mounted on the drive device, the built-in disk needs to be rotatable. It is necessary to consider face contact and eccentricity. Therefore, the disk 10
In this state, the rotation of the disk may be hindered. On the other hand, if the "play" of the gripping by the first restricting portion 752 is too large in consideration of this, the range in which the position is restricted in the thickness direction of the disk becomes wide, and the disk 10 is securely inserted into the opening 102 of the case body. It becomes difficult to do.

When the disk is housed in the adapter and mounted on the drive, it is preferable that the displacement between the center of rotation of the disk and the rotation axis of the drive be as small as possible.

Therefore, when the adapter is mounted on the drive device, it is preferable that the position of the built-in disk is regulated by a position regulating means which is gentler than the position regulation by the first regulating portion.

The adapter according to the present embodiment is realized by the second restricting portion 753 provided adjacent to the first restricting portion 752 of the disk restricting members 751a and 751b.

Hereinafter, the function of the second regulating unit will be described.

As shown in FIGS. 18, 23 and 24,

Position limiting protrusions 754 are provided at the ends of the a and 751b as contact members for contacting the door 510 so as to protrude toward the opening side of the insertion portion 602. When the door 510 is closed, the position The contact surfaces 514 and 515 are positioned by the position regulating protrusion 754 of the disc regulating member 751a and the disc regulating member 75.
1b, respectively. As a result, the disc regulating members 751a and 751b
As shown in FIG. 19, the disc regulating member 751a is rotated clockwise around the disc regulating member
b slightly rotate counterclockwise. When the door 510 is closed, the disc regulating members 751 a and 751 b are elastically held by the elastic force of the torsion coil spring 760 with the respective position regulating protrusions 754 abutting the contact surfaces 514 and 515 of the door 510.

FIG. 27 is a partial perspective view showing a state in which the door 510 is closed and the second regulating portion 753 of the disc regulating member 751a is gripping the disc 10, and FIG. 28 is a plan view thereof. When the door 510 is closed, the portions of the first regulating portions 752 of the disc regulating members 751a and 751b are separated from the disc 10, and the adjacent second regulating portions 753 sandwich the disc 10 from both sides.

As is clear from comparison with FIGS. 23 and 24, the gripping by the second restricting portion 753
The gap in the thickness direction of the disk 10 is larger than that of the gripper 52. Therefore, there is no hindrance to the rotation of the disk even if the contact and eccentricity of the disk when it is mounted on the drive device is considered. Moreover, the position of the disk in the direction parallel to the disk surface is regulated by the disk holding member 2.
02 together with the opening / closing lid 201 including
1a and 751b, the displacement between the center of rotation of the disk and the rotation axis of the drive device when mounted on the drive device can be suppressed to within an allowable range.

In the present embodiment, a part of the disk restricting member 751a constituting the disk restricting means is configured to be a part of the component of the opening / closing lid holding / unlocking means at the same time. Thus, the configuration can be simplified and the number of parts can be reduced. However, the present invention is not limited to this example, and both may be composed of separate components.

Further, when the adapter according to the third embodiment of the present invention is mounted on a drive device, the shutter 503 is provided.
Is opened, and the head of the drive device passes through the head opening windows 502 and 603. Therefore, it is necessary that the adapter and the opening / closing lid mounted inside the adapter have a shape that secures a passage area for the head.

FIG. 9 is a schematic perspective view showing a state in which a shutter 503 of the adapter 500 according to the present embodiment in which is stored is opened. FIG. 30 is a partial cross-sectional view taken along line III-III of FIG.

As shown, the adapter of the present embodiment has a bridge portion 615 in the head opening windows 502 and 603. The bridging portion 615 is used to allow the head to pass through the head opening windows 502 and 603.
And, it is thinner than the outer surface of the lower case 601 and is formed so as to step down. The thickness d11 of the stepped bridge portion 615 is formed so as to be the same thickness as the corresponding portion of the disk cartridge having external compatibility with the adapter. The head of the drive device is designed on the assumption that the maximum thickness of the inside of the head opening windows 502 and 603 is d11.
It is preferable that both the thickness d12 of the opening / closing lid holding plate 701 and the thickness d13 of the opening / closing lid 201 are equal to or smaller than the thickness d11 of the bridge portion 615.

Further, in a state where the insertion position holding means is operated, the second holding portion 1216 formed on the operation member 1210a penetrates into the second groove 1125 formed on the opening / closing lid 1120, and the opening / closing lid 1120 in the disk thickness direction is displaced. Position is regulated. Further, the first holding portion 1242 formed on the height position holding member 1240 is formed on the first lid
And the position of the opening / closing lid 1120 in the disk thickness direction is regulated (operation of the height position holding means of the second opening / closing lid holding means). Thus, the opening / closing lid 11
20 is held at a predetermined position. FIG. 46 shows this state.

Next, the door 510 is closed (FIG. 47), and the door 510 is mounted on a disk cartridge drive device which is externally compatible with the adapter 1200 to reproduce information recorded on the disk 10 in the adapter. Alternatively, information can be recorded or erased.

The above structure and function will be described below in order.

The first unlocking means, the third unlocking means, and the first opening / closing lid holding means of the present invention will be described.

[0200] The first unlocking means is an open / close lid 1120.
In a state where the first unlocking claw 205 formed on the hinge 204 formed on the first member and the first unlocking bar 1214 formed on the operating members 1210a and 1210b are in contact with each other, the knob 1218 of the operating member 1210a is moved. Upper case 1
When pushed rightward from the window 1221 of 220, the first unlocking bar 1214 attempts to move inward of the adapter 1200 and deforms the hinge 204 inward. As a result, the engagement between the first lock projection 203 and the lock hole 105 is released.

The third unlocking means is provided on the movable piece 1503 formed on the case body 1110.
When the knob 1218 of the operation member 1210a is pushed rightward from the window 1221 of the upper case 220 in a state where the second protrusions 1513 formed on the operation members 1210a and 1210b are fitted in the recesses 1512 of the second case, Convex part 1513 of
Moves toward the inside of the adapter 1200, and the movable piece 150

The holding hook 1215 formed in the opening moves inward and engages with the hook 1123 formed on the opening / closing lid 1120 to lock the opening / closing lid 1120.

As described above, the first unlocking means and the third
The opening / closing lid 1120 is left inside the adapter 1200 by the operation of the lock releasing means and the first opening / closing lid holding means,
The case main body 1110 can be removed from the adapter 1200. Of course, the operation members 1210a and 1210
When the user operates “b” to pull out the case body 1110 from the adapter 1200, the disk 10 is gripped by the opening / closing lid 1120, so that the disk 10 also remains inside the adapter 1200.

FIG. 44 shows operation members 1210a and 1210b.
Is operated to operate the first unlocking means, the third unlocking means, and the first opening / closing lid holding means. The hinge 204 is displaced, and the hook 1123 of the opening / closing lid 1120 is displaced. And a state in which the holding hooks 1215 of the operation members 1210a and 1210b are engaged.

FIG. 48 is a view showing a third lock releasing means. The second protrusions 1513 formed on the operation members 1210a and 1210b are fitted into the second recesses 1512 of the movable piece 1503 formed on the case main body 1110 (FIGS. 48A and 48B). 1210a, 12

(C)).

Next, the insertion position holding means and the height position holding means which are the second opening / closing lid holding means in the present invention will be described.

After the case main body 1110 is pulled out from the inside of the adapter 1200, the insertion position
The purpose is to regulate the position in the insertion direction so that the adapter 20 does not come off the adapter 1200. That is, when the disk cartridge 1000 is inserted into the adapter 1200,
On the side of the case body 1110, the insertion position holding member 125
0 is rotated in a direction outside the insertion portion 602. next,
By operating the operation member 1210a, the disc 10, the opening / closing lid 1
When the case main body 1110 is pulled out from the inside of the adapter while leaving the inside of the adapter 1200, the insertion position holding member 1250 is rotated in the direction of the inside of the insertion portion 602 by the urging force of the spring 1252, and the insertion position holding member 125
The first step 1250a formed on the opening / closing lid 1120
With the step 203b of the lock projection 203. Then, even if the first opening / closing lid holding means is released, the opening / closing lid 11
20 will not fall out of adapter 1200. Also, the first unlocking claw 205 formed on the opening / closing lid 1120 and the first unlocking bar 1214 formed on the operation members 1210a and 1210b allow the opening / closing lid to be positioned in a plane direction parallel to the disk surface. It is regulated, and the position of the opening / closing lid 1120 does not change accidentally.

The height position holding means controls the position of the opening / closing lid 1120 in the disk thickness direction. That is, the disk cartridge 1000 is
00, the height position holding member 1240 is moved to the outside of the insertion portion 602 on the side surface of the case main body 1110. Then, after the first opening / closing lid holding means is operated, almost simultaneously with the separation of the opening / closing lid 1120 and the case main body 1110, the height position holding member 1240 sets the spring 12
Due to the urging force of 41, it moves in the direction inside the insertion portion 602. Then, the first holding portion 1242 formed on the height position holding member 1240 enters the first groove 1124 formed on the opening / closing lid 1120, and regulates the position of the opening / closing lid 1120 in the disk thickness direction. When the disc cartridge 1000 is inserted into the adapter 1200, the second holding portion 1216 formed on the operation member 1210a enters the second groove 1125 formed on the opening / closing cover 1120, and the disc thickness of the opening / closing cover 1120 is increased. The position of the direction is regulated. Thus, the opening / closing lid 1 is held by the height position holding means.
By regulating the height position of the first flange 1126 and the second flange 1 formed on the opening / closing lid 1120,
With 502, the position in the thickness direction of the disk 10 housed inside the adapter 1200 can be regulated. At this time, it is needless to say that the shape of the second groove portion 1125 is formed longer by the amount of movement in consideration of the amount of movement of the operation member 1210a. Further, as described above, since the second holding portion 1216 and the second groove 1125 are designed to be fittable from only one direction, the A surface of the disk cartridge 1000, the A surface of the adapter 1200, and the disk cartridge B The surface and the B surface of the adapter 1200 can be attached so as to correspond to each other.

Next, a description will be given of a disc regulating means for grasping the disc and regulating the position. Note that this function is the same as that of the disk regulating means of the third embodiment, and therefore, a description will be mainly given of a portion having a different configuration. FIG. 49 is a perspective view of the disc regulating member 1280, and FIG. 50 is a side view of the disc regulating member.

The first flange 1126 of the opening / closing lid 1120
And the movable width in the disk thickness direction of the disk 10 whose position is regulated by the second flange 1502 is substantially the same as the movable width regulated by the inner wall of the disk cartridge 1000, and has a rotatable width. . When the disk 10 in such a state is to be stored in the case main body 1110, a state may be considered in which the disk 10 comes into contact with the case main body 1110 and cannot be reliably stored in the case main body 1110. The disc regulating means of the present embodiment is used to avoid such a state.

As shown in FIGS. 41, 46 and 47, the disc regulating means is rotatable about two support shafts 613 formed at both ends near the opening of the insertion portion 602, respectively. 49 and 50, a disc regulating member 1280 having a first regulating portion 1285 formed at one end thereof so as to grip the disc 10 from both sides, and a spring engagement of the disc regulating member 1280. The torsion coil spring 760 is engaged with the surface 1286 and the lower case 1230 and urges the disc regulating member 1280 toward the insertion portion 602. Disc regulating member 1280
The second restricting portion 1284 for restricting the position of the disk to such an extent that the disk can be further rotated is replaced with the first restricting portion 1285.
And are formed adjacent to it.

[0213] The operation of the disk regulating means having such a configuration will be described. As shown in FIG. 46, when the opening / closing lid 1120 and the disk 10 are mounted on the insertion portion 602, both the pair of disk regulating members 1280 are in contact with the guide member 1270. Guide member 1270
Since the position in the disk cartridge insertion direction is regulated by the stop surface 1271 provided on the guide member 1270 and the groove 1234 (see FIG. 41) formed in the lower case 1230, the disc regulating member 1280 is a torsion coil spring. By 760, it is stationary in a state of being pressed in the direction of the insertion portion 602. At this time, the first regulating portion 1285 of the disc regulating member 1280 grasps the end of the disc 10 from both sides, and regulates the position in the disc thickness direction. Therefore, when the case body 1110 is inserted into the insertion portion 602 from this state, the disc 10 can be reliably inserted into the opening 1111 of the case body 1110.

Note that the end of the disk 10 is
When the case body 1110 is further inserted into the insertion portion 602 after being inserted into the opening 1111 of the case 110, the case body contact surface 1287 on one side of the disc regulating member 1280 contacts the side surface of the case body 1110, As shown in FIG. 45, the regulating member 1280 pivots around the support shaft 613, one disc regulating member 1280 rotates clockwise, and the other disc regulating member 1280 rotates counterclockwise. It is designed to escape outside.

As shown in FIG. 46, when the door 510 is closed in a state where the disk 10 is gripped by the first restricting portion 1285, the one end of the guide member 1270 and the door 510 are interlocked with the operation of closing the door 510. Abuts on the guide member 1
270 is pushed in the disk cartridge insertion direction. As a result, the other end of the guide member 1270 presses the disc regulating member 1280, and the disc regulating member 1280 rotates around the support shaft 613 and the insertion portion 602.
One of the disk restricting members 1280
Is slightly rotated clockwise, and the other disk regulating member 1280 is slightly rotated counterclockwise.

In FIG. 47, the door 510 is closed, and the second regulating portion 1284 of the disc regulating member 1280 is
FIG. 4 is a plan view showing a state in which is gripped. When the door 510 is closed, the first regulating unit 1 of the disc regulating member 1280 is closed.
285 is in a state of being separated from the disk 10. The second regulating portion 128 of the disc regulating member 1280 in such a state
It is needless to say that the disc regulation by 4 is set larger than the disc regulation by the first flange 1126 and the second flange 1502 of the opening / closing lid 1120.

Next, an outline of a method for taking out a disk stored in the adapter according to the fifth embodiment of the present invention will be described.

The door 510 is opened from the state shown in FIG.
6) Insert the case body 1110 into the insertion portion 602 (FIG. 45). At this time, the side surface of the case main body 1110 abuts against the disc regulating member 1280, and the disc regulating member 1280 is opposed to the torsion coil spring 760, and
02. The disk 10 and the opening / closing lid 1 are stored in the disk storage portion 1112 of the case body 1110.
120 are sequentially inserted, and until they are completely stored in the disk storage portion 1112, the case body 111 is inserted.
0 is inserted into the insertion section 602 (FIG. 43). In this course,
Side surface of case body 1110 and height position holding member 124
0 abuts on the spring and the height position holding member 1240
1 is moved in the direction outside the insertion portion 602, and the height position holding means is released. Also, the case body 1110
And the insertion position holding member 1250 abuts against the insertion position holding member 1250, and the insertion position holding member 1250
To the outside direction of the. Accordingly, the means for holding the insertion position of the disk cartridge is released. As described above, according to the present embodiment, the release operation of the height position holding means and the insertion position holding means as the second opening / closing lid holding means is sequentially performed only by inserting the case main body 1110 into the insertion portion 602. Done. That is, the opening / closing lid holding / releasing means in the present embodiment does not require a special member such as the opening / closing lid holding / releasing bar 731 of the adapter 500 in the third embodiment, and the height is configured to perform the above operation. It is constituted by the components of the position holding means and the insertion position holding means.

When the case body 1110 is further inserted, the stepped portions 203b of the first lock projections 203 formed on both sides of the opening / closing lid 1120 are connected to the opening 1 of the case body 1110.
It abuts on the entrance end of 111. Since an inclined surface is formed at the entrance end of the opening 1111, the first lock projection 2
03 receives the inward force on the inclined surface, and the hinge 204 is elastically deformed. As a result, the first lock projection 203 slides on the inner wall 104 of the opening 1111 with the hinge 204 elastically deformed.

[0220] The opening / closing lid 1120 is mounted on the disk storage 1112.
When completely stored in the disk cartridge 1000,
The first locking means and the third locking means function. That is, as described with reference to FIGS. 31 to 35, when the first lock projection 203 arrives at the lock hole 105, the hinge 204 elastically recovers, and the lock projection 203 fits into the lock hole 105. And the case body 111
The opening / closing lid 1120 is fixedly held at 0. Almost simultaneously, the slope 1510 of the movable piece 1503 of the case body and the opening / closing lid 11
20 comes in contact with the third lock projection 209, and the movable piece 15
03 while the third lock projection 20 is elastically deformed inward.
9 goes through passage 209a and when it passes completely,
The movable piece 1503 returns to the original state, and the third lock projection 2
09 is hooked on the third lock hole 1511.

As described above, the opening / closing lid 1120 and the disc 1
0 can be taken out outside integrally with the case main body 1110 (FIG. 42).

As described above, according to this embodiment, the operating member 1210a is manually operated, and the first unlocking means, the third unlocking means, and the first opening / closing lid holding means are simultaneously operated. Thus, an adapter having a simple configuration can be realized.

Furthermore, since the hinge 204 formed on the lid 1120 is not elastically deformed when the lid 1120 is held in the insertion portion 602 of the adapter, the hinge 204 is not used. It is possible to prevent creep caused by the deformation.

Similarly, when the cover 1120 is held in the insertion portion 602 of the adapter, the bridge 1503a for connecting the movable piece 1503 and the case main body 1110 is connected.
Is not elastically deformed, so that even when the opening / closing lid 1120 is mounted in the adapter for a long time, the bridge portion 1503a does not undergo creep deformation.

Further, the operation of releasing the second opening / closing lid holding means proceeds only by inserting the case body 1110 into the insertion portion 602, so that the operability of taking out the disk is improved.

Further, the holding of the opening / closing lid 1120 after the opening / closing lid 1120 is mounted in the adapter is achieved by the second opening / closing lid holding means provided separately from the first opening / closing lid holding means. Even if the user operates the knob 1218 by mistake while the door 510 is open (the state shown in FIG. 46), an accident does not occur in which the opening / closing lid 1120 or the disc 10 falls from the insertion section 602. Therefore, there is no need to provide the opening / closing lid holding / unlocking means shown in the third embodiment, and the structure can be simplified.

[0227]
