The transmission gear 16 and the switching gear 18 are disengaged from each other, and at the same time, the transmission gear 16 is engaged with the transmission gear 47. The driving force is transmitted to the retracting drive arm 46 via the elevating drive gear 48, whereby the connecting lever 43 is retracted and lowered to a height that does not interfere with the height of the stocker 4. After this, the lifting drive arm 40
The driving force is transmitted to, the elevating base 6 is lowered in the direction of arrow G, and is coupled with the traverse chassis 31 to position the disc cartridge 101 at a predetermined position. After this,
The locked state by the mechanical lock mechanism is released, the traverse chassis 31 is floated by the dampers 34 and 35 together with the disc cartridge 101 and the elevating base 6, and the state becomes reproducible.

The ejecting operation of the disc cartridge 101 is the reverse of the inserting operation described above and can be easily analogized. Therefore, the description thereof will be omitted and only the closing operation of the shutter 102 will be described.

When the disk cartridge 101 is driven in the direction of arrow E, the shutter closer 25 engaged with the cutout of the shutter 102 drives the shutter 102 to be closed.

Next, the horizontal operation of pulling out the disk cartridge from the stocker and transferring it onto the traverse chassis, which is the playing position, will be described with reference to FIGS. In FIG. 6, the disc cartridge 10 is inserted into the independent insertion slot 2a.
When the disk cartridge 101 stored in the stocker 4 is selected in the state where 1 is not inserted,
By driving the double insertion blocking member 37, the independent insertion port 2a is closed, and the traverse chassis 31 is closed by 2
After preventing simultaneous mounting of the wound disk cartridge 101, the solenoid 11 is energized to drive the mode lever 14 and the transmission gear 16 meshes with the transmission gear 47. Here, the motor 9 is energized and the driving force is transmitted to the retracting drive arm 46 via the ascending / descending drive gear 48, the guide holder 36 descends in the direction of the arrow G, and the guide lever 36 together with the connecting lever 43 moves the stocker 4 into the stocker 4. It is retracted and lowered to a height that does not interfere with the height of the. After that, when the solenoid 11 is reversely energized and the mode lever 14 is driven to mesh the transmission gear 15 with the switching gear 17, the rack holder 5 can be transported.

Is inserted into a holding part at the bottom of the elevating base 6, and vertical guide regulation is performed. At this time, the rack holder 5 is first guided by the guide bosses 4b and 4c of the stocker 4,
The guide pins 6 of the elevating base 6 are sequentially arranged according to the pulling operation.
a is engaged with the guide groove 5c, and the guide pin 6
The guide is maintained by the engagement of b with the restriction groove 5d. Therefore, the rack holder 5 is always pulled out under the guidance of two or more points.

Next, in FIG. 14, the rack holder 5 is transported by the engagement of the rack gear 5a and the drive gear 7, but the engagement is constant at the time of changing direction due to the engagement of the guide groove 5c and the guide pin 6a. Since it is set so that it is rotated in the direction of arrow D. Further, at this time, the rack holder 5 is fixed to the guide pins 6 of the lifting base 6.
Due to the engagement relationship between b and the restricting groove 5d, it is slanted counterclockwise. Further, by moving the rack holder 5 in the direction of the arrow D, the cam 8b of the guide arm 8 is moved to the rack holder 5.
And the cam 8b of the guide arm 8 is raised, and the other regulating pin 8a is projected downward instead. The protruding regulation pin 8a is engaged with the notch 5e of the rack holder 5 and is used as a guide member for the subsequent transfer operation of the rack holder 5.

Next, in FIG. 15, the drive gear 7 further rotates counterclockwise, whereby the rack holder 5 engages with the rack gear 5a and the drive gear 7 and the guide groove 5 is formed.
It is transported in the direction of arrow A while its position is regulated by three guides, that is, the engagement of c with the guide pin 6a and the engagement of the notch 5e with the regulation pin 8a. At this time, the regulation groove 5d and the guide pin 6b
Are separated and do not interfere with the transfer. As shown in FIG. 16, the rack holder 5 is horizontally transferred to the playing position by the above procedure. At this time, the independent insertion port 2
The shutter drive lever 23 is driven by the transfer operation of the rack holder 5 and the shutter 102 is opened by the shutter opener 24 in the same manner as in the mounting operation of the disk cartridge 101 from a.

After that, the solenoid 11 is energized to rotate the mode lever 14, and the transmission gear 15 and the switching gear 17 are disengaged from each other. At the same time, the transmission gear 16 is meshed with the transmission gear 47. The driving force is transmitted to the raising / lowering drive arm 40 via the raising / lowering drive gear 48, whereby the raising / lowering base 6 is lowered in the direction of the arrow G, and is coupled with the traverse chassis 31 to position the disc cartridge 101 at a predetermined position. After that, the locked state by the mechanical lock mechanism is released, and the traverse chassis 31 moves together with the disc cartridge 101 and the elevating base 6 into the damper 3.
It is floated by 4, 35 and is ready for reproduction.

Stocker 4 of disk cartridge 101
The return operation to the above operation is the reverse of the above transfer operation and can be easily inferred, so the description thereof is omitted here. Next, the erroneous mounting preventing means in the playing state of the stocker 4 will be described with reference to FIGS.

In FIG. 17, the erroneous mounting preventing arms 22 configured as erroneous mounting preventing means are rotatably supported on the fixed substrate and provided in the same number so as to form a pair with the rack holders 5. 5 is abutted. The pressing spring 53 urges the erroneous mounting prevention arm 22 counterclockwise about the support shaft. Next, the operation of the erroneous mounting prevention arm 22 will be described. In FIG. 17, the rack holder 5 is inside the stocker 4 and is in a standby state. At this time, the holding convex portion 22a of the erroneous mounting prevention arm 22 is in contact with the rack holder 5, and therefore the rack holder 5 Is regulated so that it will not pop out in the pull-out direction for playing even if vibration or shock is applied. Next, in FIG. 18, when the rack holder 5 is pulled out to the performance position and is in the performance state by the regular procedure described above, the erroneous mounting prevention arm 22 is rotated in the direction of arrow J by the biasing force of the pressing spring 53. In such a state, a new disc cartridge 1 is mistakenly added.
Even if 01 is attached to the empty slot of the stocker 4 during playing, the locking operation by the lock portion 5b cannot be performed because the rack holder 5 is not inside the stocker 4. Further, since the erroneous mounting prevention arm 22 is rotated counterclockwise as shown in the drawing, the disk cartridge 101 to be mounted is pushed back in the direction of arrow E.

By the above operation, the stocker 4 is driven in conjunction with the operation of rotating the opening / closing panel 1, and the stocker 4 is locked to the housing 3 in the opened state, so that the disk cartridge 101 can be attached / detached. The operation is facilitated, and the opening / closing panel 1 does not accidentally close even if the stocker 4 is pushed during mounting. Further, since the rack holder 5 is configured to be movable only in the direction substantially perpendicular to the mounting direction of the disc cartridge 101 with respect to the stocker 4 fixed in the apparatus, the disc cartridge 101 is externally connected.
Even if it is struck in, it can obtain sufficient strength and is not damaged.

Further, the disk cartridge 101 mounted in the stocker 4 and the independent insertion slot 2a is connected to one motor 9
Drive is performed, the drive is switched by the transport operation of the disc cartridge 101, and the plurality of disc cartridges 1 are driven by one shutter opener 24 and one shutter closer 25.
In order to open and close the shutter 102 of No. 01, a shutter opening / closing member is provided in each of a plurality of storage portions having different storage positions,
The configuration can be simplified as compared with the case where the transport mechanisms are independently configured. Furthermore, since the transport drive mechanism is arranged in the area where the movement paths of the rack holder 5 in the two directions orthogonal to each other intersect, the space in the apparatus can be effectively used and the size can be reduced.

When reproducing the disc cartridge 101 from the independent insertion slot 2a, the guide holder 36 is used.
When the disk cartridge 101 is reproduced from the stocker 4 by connecting the guide holder 36 to the floating base 6 that is floated, the guide holder 36 is connected to the fixed base 42 that is not floated so as to be at the same height as the independent insertion opening 2a. Stocker 4 to disk cartridge 10
1 can be attached and detached, the device can be thinned, and the vibration-proof member can be downsized by reducing the weight of the floating portion.

Further, by providing the above-mentioned guide member and transfer means on the rack holder 5 and the elevating base 6 which are pulled out from the stocker 4, it is possible to realize a transfer mechanism which can be configured with only one side of the drive section and which can be miniaturized. Further, even when the direction is changed, the transfer can be continuously carried out in two directions without using any special switching means, so that the structure is simplified and the transfer speed can be improved as compared with the case where the drive is switched to realize the transfer in two directions. Can be improved.

Can be improved. Further, since the erroneous mounting prevention arm 22 is provided, the disk cartridge 10
When the disk cartridge 101 in the standby state of the stocker 4 is replaced in the playing state of No. 1, the mistake is prevented because the disk cartridge 101 is immediately pushed back even if it is mistakenly attempted to be inserted in the slot being played.

[0045]

As described above, according to the present invention, the erroneous mounting preventing means stores the desired one disk cartridge in the storage rack in association with the transfer operation when the desired one disk cartridge is pulled out and transferred by the cartridge transfer means. It elastically projects toward the manual loading port side of the disk cartridge in the shelf. As a result, even if the user mistakenly tries to insert a new disc cartridge, the wrong mounting prevention means pushes back the disc cartridge, so that the disc cartridge is prevented from being mounted and the user can immediately notice the wrong operation. You can

The erroneous mounting prevention means can hold the cartridge transfer means other than the pulled-out cartridge transfer means in a standby state by an elastic urging force to restrict the protrusion in the pull-out direction due to vibration. it can.

Therefore, even in the playing state, it is possible to replace the disk cartridge waiting in the accommodating section, and a new disk cartridge is inserted into the empty disk stocker section that has been pulled out for playing. Even in the case of occurrence, trouble can be prevented from occurring, and better operability can be obtained.
