[Problem that the invention attempts to solve]

However, the conventional disc player described above has the following problems.

In other words, when a disk cartridge is installed in a disk player, this status is normally indicated by an indicator lamp, etc., but if the indicator lamp, etc. is malfunctioning, the status cannot be known and the disk cartridge is not installed. Even though the disk cartridge is installed, there are many cases where a user accidentally inserts a different disk cartridge into the cartridge insertion slot. Furthermore, when the power is turned off without ejecting the disk cartridge from inside the disk player, a similar erroneous operation is likely to occur. And if there is an error in inserting the disk cartridge twice like this,
It became impossible for the carrier to pull in and eject the disk cartridge at all.
This is a fatal problem for this type of disc player.

Therefore, the present invention attempts to lock the opening/closing lid in the closed state to prevent double insertion of another disk cartridge when a disk cartridge is already installed in the cartridge mounting position. .

[Means for solving problems]

The present invention provides an opening/closing lid that is provided to open and close a cartridge insertion opening and is configured to be pushed open by a disk cartridge inserted from the cartridge insertion opening to a cartridge insertion position, and a lid for opening and closing a cartridge insertion opening. and a cartridge mounting position provided with a turntable. a carrier that is mounted on a turntable from above, and is driven by the forward movement of the carrier from the cartridge insertion position to the cartridge mounting position to forcibly close the opening/closing lid, and the cartridge of the carrier an opening/closing lid opening/closing mechanism configured to open the opening/closing lid by being driven by a return movement from the mounting position to the cartridge insertion position; The disk is lowered by forward movement from the cartridge insertion position to the cartridge installation position, and the disk is pressed and fixed from above on the turntable, and the carrier is moved from the cartridge installation position to the cartridge insertion position. A clamper configured to be raised by double movement and separated upward from the disk on the turntable, and a clamper configured to be inserted and removed within the opening/closing locus of the opening/closing lid, and configured to be freely inserted and removed by the descent of the clamper. The clamper is inserted into the opening/closing locus of the opening/closing lid and locking the opening/closing lid in the closed state, and is removed from the opening/closing trajectory of the opening/closing lid by the rise of the clamper, thereby locking the opening/closing lid in the closed state. This disc player is equipped with a lock member for releasing the lock.

[Effect]

In the disk player of the present invention, when a disk cartridge is installed, the opening/closing lid is pushed open by the disk cartridge when the disk cartridge is inserted into the cartridge insertion device from the cartridge insertion opening. Thereafter, the carrier pulls the disk cartridge from the cartridge insertion position to the cartridge mounting position, and the disks in the disk cartridge are mounted onto the turntable from above. At this time, the opening/closing lid opening/closing mechanism is driven by the carrier that is moved from the cartridge insertion position to the cartridge mounting position to forcibly close the opening/closing lid, and the clamper is driven downward by the carrier. The clamper presses the disk onto the turntable from above and fixes it. Furthermore, the lowering of the clamper drives the locking member, inserting the locking member into the opening/closing trajectory of the opening/closing lid, locking the opening/closing lid in the closed state, and moving the cartridge from the cartridge insertion slot to the cartridge insertion position. This is to prevent double insertion of the disk cartridge.

When ejecting the disk cartridge, the above-mentioned reverse operation is performed, and when the carrier ejects the disk cartridge from the cartridge mounting position to the cartridge insertion position, the carrier moves the clamper upward from the disk on the turntable. At the same time, the locking member is moved out of the opening/closing trajectory of the opening/closing lid to release the locked state of the opening/closing lid, and the opening/closing lid is forcibly opened by the opening/closing mechanism. This is how it was done.

〔Example〕

An embodiment of a disc player to which the present invention is applied will be described below with reference to the drawings.

The opening/closing lid opening/closing mechanism and the opening/closing lid locking mechanism of the present invention will be explained mainly with reference to FIGS. 1A to 4, but first, the structure of the disk player 1 and its operation will be explained with reference to FIGS. 5A and 5B. Outline.

The disk player 1 is configured in a front loading type, and a front panel 2 is provided with a cartridge insertion slot 3, and inside the disk player 1 are a carrier 4, a turntable 5, a clamper 6, a writing (recording) /or a reading (reproduction) head 7, etc. are provided. The carrier 4 has a tray 8 arranged horizontally, and a pair of left and right rack plates 9 arranged vertically and parallel to each other on the left and right sides of the tray 8.

In this disk player 1, first, the disk cartridge 11 is horizontally inserted into the cartridge insertion opening 3 from the front end 11a side in the direction of arrow a, as shown by the two-dot chain line in FIG. 5A. Then, as shown by the solid line, disk cartridge 1
1 is completely inserted into the carrier 4 from the direction of arrow a, placed horizontally on the tray 8, and stopped.
Here, the rear end 11b side of the disk cartridge 11 horizontally inserted into the carrier 4 is in a state of protruding out of the front panel 2 from the cartridge insertion opening 3. This state is the cartridge insertion position.

Next, after the disk cartridge 11 is horizontally inserted into the carrier 4 as described above, the pinion 14 is started to rotate by a motor (not shown).
Disk cartridge 1 due to forward movement of carrier 4
A loading operation of No. 1 is started. That is, when the pinion 14 is rotated by the motor to drive the rack 15 of the rack plate 9, a pair of front and rear guide rollers 16 pivotally attached to both the front and rear ends of the rack plate 9 are fixed horizontally to the chassis side. The rack plate 9 is rolled within the guide rail 17, thereby horizontally driving the rack plate 9 in the direction of arrow a. At this time, the tray 8 is also horizontally transferred together with the rack plate 9 in the direction of the arrow a, and the tray 8 is automatically moved in the direction of the arrow a from the cartridge insertion position shown by the solid line to the cartridge retraction position shown by the dashed line. I'm drawn into it. As a result, the disk cartridge 11 is completely drawn into the disk player 1 from the cartridge insertion opening 3 by the carrier 4, and
The disk cartridge 11 is horizontally transferred to a position directly above the turntable 5. In this state, the tray 8 is stopped.

On the other hand, the arrow a on the rack plate 9 by the pinion 14
The horizontal drive in the direction continues even after the tray 8 is stopped at the cartridge retraction position. Then, as shown in FIG. 5B, the rack plate 9 is
When the tray 8 continues to be driven horizontally in the direction shown in FIG. By vertically lowering the tray 8, the disk cartridge 11 is vertically lowered, and the disks 12 in the disk cartridge 11 are mounted horizontally on the turntable 5. Furthermore, this disk 1
2 is, for example, a disk called a draw disk (DRAW/DISC) that can be written (recorded) and read (reproduced) by an optical method or a magneto-optical method, and has recording surfaces formed on both the top and bottom surfaces. is used. And disk 12 is turntable 5
When mounted horizontally on the turntable 5, the disk 12 is pressed onto the turntable 5 by the clamper 6, and the head 7 is brought close to the lower recording surface of the disk 12.

As described above, the operation of retracting the disk cartridge 11 to the cartridge mounting position by the forward movement of the carrier 4 is completed.

Further, the ejection (unloading) operation of the disk cartridge 11 to the cartridge insertion position by the backward movement of the carrier 4 is performed by an operation completely opposite to the above-described retraction operation.

Next, as shown in FIGS. 1A to 1E, a pair of opening/closing lids 20 and 2 provided on the disk player 1 will be described.
1 and these opening/closing lid opening/closing mechanisms 22 will be explained.

First, a pair of upper and lower opening/closing lids 2 are installed inside the cartridge insertion slot 3 of the front panel 2 of the disk player 1.
0 and 21 are provided. These pair of opening/closing lids 20 and 21 are molded from synthetic resin, extend along the left and right longitudinal direction of the cartridge insertion opening 3, and have a substantially L-shaped cross section. The pair of opening/closing lids 20, 21 are configured as so-called double-door opening/closing lids that are rotated vertically from the center to open/close by shafts 23, 24 integrally formed at both left and right ends of the opening/closing lids. ing. And shafts 2 at both left and right ends of the pair of opening/closing lids 20 and 21
3 and 24 are integrally formed with gears 25 and 26, respectively, and these gears 25 and 26 are respectively engaged with a pair of intermediate gears 27 and 28 that engage with each other. Therefore, the pair of opening/closing lids 20 and 21 are configured to be opened and closed simultaneously in conjunction with each other.
The gears 25, 26 and the intermediate gears 27, 28 are pivotally supported by a bracket (not shown) fixed to the chassis side.

Next, the opening/closing lid opening/closing mechanism 22 is composed of an interlocking rod 32 and a guide block 33. That is, a support shaft 3 is provided on the chassis side of the disk player 1.
4, an interlocking rod 32 is rotatably attached. A toothed portion 35 is formed at one end of the interlocking rod 32, and this toothed portion 35 is engaged with the intermediate gear 28. Further, a roller 36 is rotatably pivotally attached to the other end of the interlocking rod 32. The interlocking rod 32 is urged to rotate in the direction of arrow c by a spring 37, and its rotation in the direction of arrow c is restricted by a stopper 38.

On the other hand, a guide block 33 is fixed to the outer surface of the rack plate 9. This guide block 33
has an almost inverted trapezoidal shape, and has a pair of slopes 33a3 at the front and rear.
3b and a horizontal surface 33c intermediate therebetween. Then, the roller 3 of the interlocking rod 32 falls within the movement locus of the guide block 33 due to the movement of the rack plate 9.
6 is located, and this interlocking rod 32 is configured to be rotated while being restricted by a pair of slopes 33a, 33b and a horizontal surface 33c of the guide block 33.

Next, a pair of opening/closing lids 2 configured as described above will be described.
0, 21 and the operation of these opening/closing drive mechanisms 22 will be explained.

First, in FIG. 1A, before the disk cartridge 11 is inserted into the cartridge insertion slot 3, the interlocking rod 32 is moved by the arrow C by the spring force of the spring 37.
The gear 26 is rotated by the teeth 35 of the interlocking rod 32 via the intermediate gear 28, and the opening/closing lid 21 is closed. At the same time, the gear 25 is also rotated via the intermediate gear 27, and the opening/closing lid 20 is also closed. Therefore, the pair of opening/closing lids 20 and 21 are completely closed to close the cartridge insertion opening 3.

Next, when the disk cartridge 11 is inserted from the front end 11a side into the cartridge insertion slot 3 in the direction of arrow a, the disk cartridge 11
A pair of opening/closing lids 20, 21 by the tip 11a of the
is pushed open up and down. At this time, as shown in FIG. 1B, the disk cartridge 11 is sandwiched between the pair of opening/closing lids 20 and 21 from above and below, and in this state, the disk cartridge 11 is inserted into the carrier 4, and the above-mentioned cartridge It is inserted to the insertion position and then stopped. In addition, a pair of opening/closing lids 20,
21 is pushed open, the intermediate gear 28
The interlocking rod 32 is rotated in the direction of arrow c' against the spring 37 through the interlocking rod 37, but the roller 36 of the interlocking rod 32 is located within the movement locus of the guide block 33.

Next, from the state shown in FIG. 1B, the rack plate 9 is
When the carrier 4 starts pulling in the disk cartridge 11, the slope 33a of the guide block 33 of the rack plate 9 comes into contact with the roller 36 of the interlocking rod 32, and the slope 33a
The roller 36 sinks under the horizontal surface 33c of the guide block 33 due to the guiding action of the guide block 33. As a result, the interlocking rod 32 is moved by the spring 37 as shown in FIG.
The interlocking rod 32 is rotated in the direction of arrow c' against the
The tooth portion 35 rotates the gear 26 via the intermediate gear 28, and the opening/closing lid 21 is forcibly opened. At the same time, the gear 25 is also rotated via the intermediate gear 27, and the opening/closing lid 20 is forcibly opened. In this way, in conjunction with the start of the retracting operation of the disk cartridge 11 by the carrier 4, the pair of opening/closing lids 2
0 and 21 are forcibly opened completely, and the disk cartridge 11 is drawn in between the pair of opening/closing lids 20 and 21 in the direction of arrow a.

When the disk cartridge 11 is completely pulled into the cartridge insertion slot 3 up to the rear end 11b, the roller 36 of the interlocking rod 32 slides 33b onto the slope of the guide block 33, as shown in FIG. 1D.
The interlocking rod 32 is rotated in the direction of arrow c by the spring force of the spring 37.
As a result, contrary to the above, the opening/closing lid 21 is forcibly closed, and at the same time, the opening/closing lid 20 is also forcibly closed. That is, immediately after the disk cartridge 11 is completely drawn into the cartridge insertion port 3, the pair of opening/closing lids 20, 21 are forcibly closed completely, and the cartridge insertion port 3 is closed again.

Thereafter, the disk cartridge 11 is further pulled in the direction of arrow a by the carrier 4, passes through the cartridge retraction position, is vertically lowered in the direction of arrow b as shown in FIG. 1E, and is installed at the cartridge mounting position. Ru.

Next, the opening and closing of the pair of opening/closing lids 20 and 21 during the ejection operation of the disk cartridge 11 is performed by a completely opposite operation to the above-described retraction operation.

That is, as shown in FIGS. 1E to 1D, after the carrier 4 is vertically raised in the direction of arrow b', it is further moved back in the direction of arrow a', and the rear end of the disk cartridge 11 in the carrier 4 is lifted vertically in the direction of arrow b'. When the portion 11b side approaches the cartridge insertion opening 3 side, the slope 33b of the guide block 33 touches the roller 36 of the interlocking rod 32.
Due to the guiding action of this slope 33b, the roller 36 sinks under the horizontal surface 33c of the guide block 33. As a result, the interlocking rod is rotated in the direction of arrow c' against the spring 37, as shown in FIG. 1C, and the pair of opening/closing lids 20, 21 are forcibly opened completely. And these pair of opening/closing lids 20, 2
1, the disk cartridge 11 is ejected from the rear end 11b side in the direction of arrow a'.

Next, when the discharge operation of the disk cartridge 11 approaches the completion stage, the rollers 36 of the interlocking rod 32 are guided by the slope 33a of the guide block 33, so that the interlocking rod 3 is moved as shown in FIG. 1B.
2 is rotated in the direction of arrow c by the spring force of spring 37. As a result, the pair of opening/closing lids 20, 21 are closed, and the disk cartridge 11 is sandwiched between the pair of opening/closing lids 20, 21 from above and below. Immediately after this, the backward movement of the carrier 4 in the direction of arrow a' is stopped, and the disk cartridge 11 is stopped at the cartridge insertion position.

When the disk cartridge 11 is pulled out from the cartridge insertion slot 3 in the direction of arrow a', the interlocking rod 32 is further rotated in the direction of arrow c by the spring force of the spring 37, as shown in FIG. 1A. Therefore, the pair of opening/closing lids 20 and 21 are forcibly closed completely, and the cartridge insertion opening 3 is completely closed again.

The opening/closing lid opening/closing mechanism 22 forcibly opens and closes the pair of opening/closing lids 20 and 21 in conjunction with the start of the retracting operation of the disk cartridge 11 by the carrier 4, the completion of the retracting operation, and the ejecting operation, respectively. Therefore, these pair of opening/closing lids 2
The opening/closing operations of 0 and 21 and their timing are extremely reliable.

Moreover, especially in this embodiment, the pair of opening/closing lids 20 and 21 are opened and closed by the guide block 33 that moves with the reciprocating motion of the carrier 4 and the interlocking rod 32 that is regulated by and interlocks with this guide block 33. The lid opening/closing mechanism 2
2 can be made extremely simple.

Next, the opening/closing lid locking mechanism 40 for locking the pair of opening/closing lids 20, 21 in the closed state will be explained with reference to FIGS. 1D to 4. The opening/closing lid locking mechanism 40 is located in the upper front of the disc player 1, approximately at the center in the left-right direction.

First, the locking member 41 has a locking piece 42 at its front end, and a shaft 43 at its rear end is rotatably supported by an interlocking member 44. and lock member 41
is urged to rotate downward (in the direction of arrow d in FIG. 1D) by the torsion coil spring 45, and this rotation is regulated by the front end 44a of the connecting member 44, so that the locking member 41 and the interlocking member 44 are is almost in a straight line. A shaft 46 is attached to the rear end of the connecting member 44 , and the shaft 46 is inserted into a pair of arcuate guide holes 48 formed in the fixing member 47 . On the other hand, the opening/closing lid lock mechanism 40 is located on the chassis side.
A support member 50 for supporting is attached. A slide member 51 is connected to a long hole 52 and a screw shaft 5 on the lower side of the support member 50 which has a substantially U-shaped cross section.
3 so as to be slidable in the front-back direction. The shaft 43 of the lock member 41 is supported between the left and right sides 51a of the slide member 51 that slides along the inside of the left and right sides 50a of the support member 50. This shaft 43 is the support member 5
A pair of elongated holes 5 provided on both left and right sides 50a of 0
4 and is attached by screws 55.
Note that the fixed member 47 is fixed to the support member 50.

Therefore, this opening/closing lid locking mechanism 40 is
As shown in the figure, when the slide member 51 is sliding in the direction of the arrow e, the slide member 51
The shaft 43 of the locking member 41 is guided by a pair of long holes 54 in the left and right sides 50a of the support member 50 and slid in the direction of arrow e. At this time, the shaft 46 of the connecting member 44 is guided by the lower ends of the pair of guide holes 48 of the fixed member 47, so that the connecting member 44 is rotated about the shaft 43 in the direction of arrow f. As a result, the connecting member 4
The front end 44a of the locking member 41 rotates the locking member 41 in the direction of arrow g, and the locking piece 42 at the front end of the locking member 41 follows its opening/closing trajectory at the rear surface of the pair of opening/closing lids 20, 21 at approximately the center in the left and right longitudinal direction. Being separated from within. Further, as shown in FIG. 1E, when the slide member 51 is sliding in the direction of arrow e',
The shaft 43 of the lock member 41 is guided by the left and right sides 51a of the slide member 51 into a pair of elongated holes 54 in the left and right sides 50a of the support member 50.
It is slid in the e′ direction. At this time, the shaft 46 of the connecting member 44 is connected to the pair of guide holes 4 of the fixed member 47.
8, the connecting member 44 is rotated about the shaft 43 in the direction of arrow f'. As a result, the locking member 41, which is integrated with the connecting member 44 by the torsion coil spring 45, is rotated in the direction of arrow g', and the locking piece 42 at the front end of the locking member 41 is connected to the pair of opening/closing lids 20, It is inserted into the opening/closing trajectory on the back side of 21. In this manner, as the slide member 51 slides, the lock piece 42 at the front end of the lock member 41 is moved forward and rotated downward, and is inserted into the opening/closing locus of the pair of opening/closing lids 20 and 21. Further, the lock piece 42 is configured to be rotated upward while being retracted and removed from the opening/closing locus of the pair of opening/closing lids 20, 21.

Next, the operation of the opening/closing lid locking mechanism 40 constructed as described above will be explained. Note that this operation is performed in conjunction with the operation of pressing the disk cartridge 11 onto the turntable 5 by the aforementioned clamper 6. FIG. 4 shows the elevating mechanism 58 of the clamper 6 and its elevating and lowering operation mechanism 59.

First, as explained in FIG. 5B, when the rack plate 9 is continuously driven horizontally in the direction of the arrow a to lower the disk cartridge 11 onto the turntable 5, the rear end surface 9a of the rack plate 9 moves up and down. It comes into contact with the roller 61 of the operating lever 60 and rotates the elevation operating lever 60 in the direction of arrow h. Then, the interlocking link 62 is pushed out in the direction of arrow i, and the drive lever 64 is rotated in the direction of arrow j about the support shaft 65 against the force of the spring 63. As a result, the link mechanism 66 of the elevating mechanism 58 is combined in a substantially Y-shape.
As a result, the clamper 6 is vertically lowered. This clamper 6 presses and fixes the disk cartridge 11 on the turntable 5.

At this time, due to the rotation of the drive lever 64, the lock operation lever 68 is moved around the support shaft 69 by the arrow h
rotated in the direction. As shown in FIG. 3, the support shaft 69 is provided on the protrusion 50b at the rear end of the support member 50, and one end 68a of the lock operation lever 68 is connected to the rear end 51b of the slide member 51 via a limiter spring 70. connected. Therefore, when the lock operation lever 68 is rotated in the direction of the arrow h, the slide member 51 is moved to the first E position via the limiter spring 70.
As shown in the figure, it is slid inside the support member 50 in the direction of arrow e'.

Then, in FIG. 1E, the arrow of the slide member 51
By sliding in the e' direction, the connecting member 44 moves forward and rotates in the arrow f' direction, and the locking member 41 moves forward and rotates in the arrow g' direction. At this time,
The pair of opening/closing lids 20 and 21 have already been connected to the opening/closing lid opening/closing mechanism 2.
2, the locking piece 42 of the locking member 41 is connected to the pair of opening/closing lids 2.
A pair of opening/closing lids 20, 21 on the back of 0, 21
As a result, the pair of opening/closing lids 20, 21 are locked in the closed state. That is, even if another disk cartridge 11' is inserted from the cartridge insertion port 3 in this state, the opening of the pair of opening/closing lids 20 and 21 is prevented by the lock piece 42 of the locking member 41, so that another disk cartridge 11' is inserted into the cartridge insertion slot 3. Erroneous operations such as double insertion of the cartridge 11' into the disc player 1 can be completely prevented. If, for example, your hand gets caught between the pair of opening/closing lids 20 and 21 and the lock member 41 cannot be completely rotated in the direction of arrow g', the limiter spring 70 will prevent one end 68a of the lock operating lever 68 from being rotated. Rotation is absorbed.

Next, when the disk cartridge 11 is ejected from the cartridge mounting position, the spring force of the spring 63 of the elevating and lowering operation mechanism 59 causes the elevating and lowering operation mechanism 59 to operate in a completely opposite manner to that described above. When the lock operating lever 68 is rotated in the direction of arrow h', one end 68a of the lock operating lever 68 is moved to the slide member 5.
1, and thereby the slide member 51 is slid in the direction of arrow e as shown in FIG. 1D. Then, the connecting member 4
4 is rotated in the direction of arrow f while retreating, and lock member 41 is rotated in the direction of arrow g while retreating. As a result, the locking piece 42 of the locking member 41 is removed from the opening/closing locus of the pair of opening/closing lids 20, 21 on the back side of the pair of opening/closing lids 20, 21, and the locking piece 42 of the locking member 41 is removed from the opening/closing locus of the pair of opening/closing lids 20, 21 in the closed state of the pair of opening/closing lids 20, 21. The lock is released. Thereafter, as described above, the pair of opening/closing lids 20 and 21 are opened by the opening/closing lid opening/closing mechanism 22 in conjunction with the ejection operation of the disk cartridge 11, and the disk cartridge 11 is ejected.

As described above, the locking member 41 is operated by the opening/closing lid locking mechanism 40 in conjunction with the loading operation of the disk cartridge 11 into the cartridge loading position and the operation of ejecting the cartridge from the loading position.
The operation of locking and unlocking the pair of opening/closing lids 20, 21 by the locking member 41 when closing the pair of opening/closing lids 20, 21 becomes extremely reliable. In particular, in this embodiment, the opening/closing lid locking mechanism 40 is operated in conjunction with the lifting/lowering operation of the clamper 6 which is raised and lowered by the reciprocating movement of the carrier 4, so a special drive source is required for the opening/closing lid locking mechanism 40. There is no need to provide a

In addition, in the opening/closing lid locking mechanism 40 of this embodiment, since the locking member 41 is rotated while moving forward and backward, the lock piece 42 of the locking member 41 is moved toward the rear side of the pair of opening/closing lids 20 and 21 in the locked state. The pair of opening/closing lids 20, 21 can be locked extremely reliably by the locking member 41.

Note that the locking member 41 of the opening/closing lid locking mechanism 40
It is also possible to integrate the connecting member 44 with the connecting member 44 . However, in this embodiment, since the lids are constructed as separate bodies, the pair of opening/closing lids 2 can be opened and closed by the locking member 41.
Locking of 0 and 21 can be performed more reliably than in the case of a single item. That is, when an attempt is made to insert another disk cartridge 11' when the pair of opening/closing lids 20 and 21 are locked in the closed state as shown in FIG. is applied to the locking piece 42 in the direction of arrow k.
The direction of this pressing force is parallel to the long hole 54 of the support member 50, so if the lock member 41 and the connecting member 44 are integrated, they are likely to be pushed back as a whole along the long hole 54 of the support member 50. There is a possibility that the pair of opening/closing lids 20 and 21 will be opened. However, when the lock member 41 and the connecting member 44 are separate bodies as in this embodiment, the lock member 41
When a force is applied to the lock piece 42 in the direction of the arrow k, a rotational force is applied to the lock member 41 in the direction of the arrow g' about the shaft 43. Since this rotational force is applied to the front end 44a of the connecting member 44 in the direction of arrow l, a rotational force is applied to the connecting member 44 in the direction of arrow f' around the shaft 43, and this rotational force is guided by the shaft 46. The guide holes 48 are received by the upper ends of the pair of guide holes 48 . In this way, the shaft 43 of the locking member 41
The locking member 41 is not pushed back along the elongated hole 54 of the support member 50, and the locked state of the locking member 41 is completely maintained.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various effective changes can be made based on the technical idea of the present invention.

For example, in the embodiment, the opening/closing lid opening/closing mechanism was constructed with a guide block provided on the rack plate of the carrier and an interlocking rod that is regulated by the guide block and interlocks with the other. Can be changed to a valid configuration.

Further, the structure for inserting and removing the opening/closing lid into the opening/closing trajectory by the locking member of the opening/closing lid locking mechanism is not limited to the structure of the embodiment, but can be changed to various effective structures.

In the embodiment, a pair of opening/closing lids that are pushed open in a double-door shape is used, but the opening/closing lids may have a single-piece structure.

Furthermore, the present invention is not limited to disk players in disk cartridges that house draw disks, but can be applied to disk players in disk cartridges for various purposes that house various types of recording and/or playback disks. .

As described above, in the present invention, when installing a disk cartridge, the opening/closing cover is pushed open and the disk cartridge is inserted from the cartridge insertion opening to the cartridge insertion position, and the carrier moves the disk cartridge from the cartridge insertion position to the cartridge installation position. and the disk in the disk cartridge is mounted on the turntable from above, and the disk is pressed and fixed onto the turntable by a clamper that is driven downward by the carrier, When ejecting a disk cartridge, when the carrier ejects the disk cartridge from the cartridge mounting position to the cartridge insertion position, the carrier drives the clamper upward to move the clamper upward from the disk on the turntable. Since they are configured to be spaced apart, there is no need to use a turntable elevating and lowering mechanism, which is a large and complex structure to drive a large and heavy turntable up and down, and the structure is very simple.

Since the turntable is not raised or lowered at all, the mounting height of the disk, which is mounted on the turntable and fixed by being pressed onto the turntable by a clamper, relative to the recording and playback head is always accurate, making it possible to record and playback the disk. Can always be performed with high precision.

Since the disk can be mounted on the turntable while it is stored inside the disk cartridge, unlike the case where the disk is pulled out of the disk cartridge one by one and mounted on the turntable, the disk can be taken in and out of the disk cartridge. The structure of the disk cartridge itself is very simple.

When installing a disk cartridge, simply insert the disk cartridge from the cartridge insertion slot into the cartridge insertion position, and the carrier can pull the disk cartridge from the cartridge insertion position to the cartridge installation position, and the disk cartridge At the time of ejection, the disk cartridge ejected from the cartridge mounting position to the cartridge insertion position by the carrier can be simply pulled out of the cartridge insertion slot. Cartridge loading and unloading operations are very easy.

When installing the disc cartridge, the carrier closes the opening/closing lid, lowers the clamper, and inserts the locking member into the opening/closing trajectory of the opening/closing lid to lock the opening/closing lid in the open/closed state. The structure is configured to prevent double insertion of the disk cartridge, and when the disk cartridge is ejected, the clamper is raised by the carrier and the locking member is moved out of the opening/closing trajectory of the opening/closing lid to lock the opening/closing lid in the closed state. Since the structure is such that the opening/closing lid is forcibly opened by releasing the opening/closing lid, all three members, the opening/closing lid, the clamper, and the locking member, can be driven only by the carrier, and the disk drive is very simple in structure. Double insertion of cartridges can be prevented.
