Next, the opening operation of the rotating panel will be described. As shown in FIGS. 2 and 4, when the rotating panel 1 is closed, the front surface 1a of the rotating panel 1 is formed to be substantially flush with the front surface 2b of the fixed panel, and the stocker 4 is a disk cartridge. The front surface of 101 is stored inside the housing 3 with respect to the rear surface 2 d of the fixed panel 2.

From this state, when the eject button (not shown) of the rotary panel 1 is pressed by the operator, the engagement state of the lock portion (not shown) of the rotary panel 1 is released, and the rotary panel is released. 1 rotates in the direction of arrow H. As a result, the stocker 4 is driven by the ejection drive lever 50 into the drive groove 4d.
Are driven to move in the direction of arrow E, and the rotating panel 1
In the state in which the rotating operation is completed (FIGS. 1 and 5), the disc cartridge 101 projects forward from the front surface 2b of the fixed panel 2, and the disc cartridge 101 can be attached and detached. At this time, the lock lever 51 slides along the guide groove 49a of the side plate 49 in the direction of the arrow D, the lock lever 51 is elastically biased by the coil spring 52, and one end of the lock lever 51 is moved to the stocker 4 side. The lock is performed by engaging with the lock groove portion 4e. Accordingly, even if the stocker 4 is pressed in the direction of the arrow A by the mounting operation of the disc cartridge 101 or the like, the stocker 4 does not move and the rotating panel 1 is not accidentally closed. In FIG. 1, when the disc cartridge 101 is mounted, the disc cartridge 101 is fixed to the fixed panel 2.
Since it is stored in the stocker 4 while being regulated and guided by the guide surface 2c, the reliable attachment / detachment operation can be performed.

The closing operation of the rotating panel 1 is the reverse operation of the opening operation described above and can be easily analogized, so that the description thereof is omitted here. Next, the mounting operation of the disc cartridge from the independent insertion slot will be described with reference to FIGS.

In an initial state in which the disc cartridge 101 is not mounted in the independent insertion slot 2a, as shown in FIGS. 6 to 9, the elevating base 6 has the independent insertion slot 2a of the fixed panel 2.
The guide holder 36 is positioned at the same height as the guide holder 36 and is engaged with the elevating base 6. From this state, when the disc cartridge 101 is inserted into the independent insertion slot 2a in the direction of arrow A as shown in FIG.
Both ends of 1 are guided and supported by the elevating base 6 and the guide holder 36, and the disc cartridge 101 is engaged with a lock member (not shown) in the guide holder 36 to be positioned. When the disk cartridge 101 is further inserted against the urging force of the holder urging lever 27, the guide holder 36 is driven in the direction of arrow A, and the holder urging lever 27 is rotated to rotate the drive switching lever 2

At the end of the carrying operation, the disc cartridge 101 causes the opening / closing stroke L1 of the shutter 102.
When conveyed by a stroke L2 (second stroke) shorter than (first stroke), the shutter drive lever 23 is swung by the guide holder 36, and the stroke of the shutter opener 24 is enlarged to move in the direction of arrow E. It is slidably driven, and the shutter opener 24 is driven by a stroke L4 (fourth stroke) in a guide groove provided on the side surface of the disc cartridge 101, and then is engaged with the shutter 102 and driven by a stroke L1 to be in an open state. To be At this time, the disc cartridge 101
The movement amount L2 of the shutter opener 24 and the movement amount L3 of the shutter opener 24 (third stroke = L1 + L4) are set to L2 <L3 (see FIG. 1).

When the disc cartridge 101 is conveyed to the position corresponding to the reproduction position, the solenoid 11 is energized to rotate the mode lever 14 and the transmission gear 15
And the switching gear 18 are disengaged from each other, and at the same time, the transmission gear 16 meshes with the transmission gear 47. The drive force is transmitted to the retract drive arm 46 shown in FIG. 9 via the elevating drive gear 48, whereby the connecting lever 43 retracts and descends to a height that does not interfere with the height of the stocker 4. Thereafter, the driving force is transmitted to the lifting drive arm 40, and the lifting base 6 is lowered in the direction of arrow G as shown in FIG.
And the disc cartridge 101 is positioned 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 disk cartridge 101 and the elevating base 6 into the damper 34,
It is floated by 35 (FIG. 10) and becomes ready for reproduction.

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 in FIG. 10, the shutter 10 is moved by the shutter closer 25 engaged with the notch of the shutter 102.
2 is driven to be closed.

Next, the horizontal operation of pulling out the disk cartridge from the stocker and transferring it to the traverse chassis at the playing position will be described with reference to FIGS.

When the disc cartridge 101 stored in the stocker 4 is selected when the disc cartridge 101 is not inserted into the independent insertion slot 2a in FIG. 6, the double insertion blocking member 37 shown in FIG. 16 is driven. As a result, the independent insertion port 2a is closed, and the two-fold disc cartridge 10 is attached to the traverse chassis 31.
It prevents that 1 is installed at the same time. In addition, the lock control means (not shown) of the rotating panel 1 restricts the engagement state of the lock portion (not shown) of the rotating panel 1 to make the rotating panel 1 unrotatable, and the stocker 4 The disk cartridge 101 is prevented from being mounted in the empty opening after the disk cartridge 101 is pulled out from the disk cartridge 101. After that, the solenoid 11 is energized and the mode lever 14
Is driven, 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 shown in FIG. 11 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. 36 retracts and descends to a height that does not interfere with the height of the stocker 4. After that, the solenoid 11 is reversely energized, and the mode lever 1 shown in FIG.
When 4 is driven and the transmission gear 15 meshes with the switching gear 17, the rack holder 5 can be transported.

First, in FIG. 13, by rotating the drive gear 7 counterclockwise, the cam 7a engages with the protrusion 5f of the rack holder 5, and the rack holder 5 starts moving in the direction of arrow B. Next, by moving the rack holder 5,
Since the rack gear 5a of the rack holder 5 meshes with the drive gear 7, the rack holder 5 is continuously moved in the arrow B direction. The rack holder 5 pulled out from the stocker 4 is inserted into the lower holding portion of the elevating base 6, and the 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, but the guide pins 6a of the elevating base 6 are sequentially arranged in accordance with the pulling operation.
Is engaged with the guide groove 5c, and the guide pin 6b
The guide is continued by the engagement of 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 maintained at a constant interval even when the direction is changed by 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 biased counterclockwise obliquely due to the engagement relationship between the guide pin 6b of the elevating base 6 and the restriction groove 5d. 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.
, The cam 8b of the guide arm 8 is lifted, and the other regulating pin 8a projects downward instead. The protruding restriction pin 8a engages 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, as the drive gear 7 further rotates counterclockwise, the rack holder 5 engages the rack gear 5a and the drive gear 7, the engagement between the guide groove 5c and the guide pin 6a, and the notch 5e. While the position is regulated by the three guides of the engagement of the regulation pin 8a, the arrow A
Is transferred in the direction. At this time, the regulation groove 5d and the guide pin 6b are separated from each other and do not interfere with the transfer. FIG.
As shown in FIG. 6, the rack holder 5 is horizontally transferred to the playing position by the above procedure. At this time, the shutter drive lever 23 is driven by the transfer operation of the rack holder 5 to drive the shutter opener 2 in the same manner as the mounting operation of the disc cartridge 101 from the independent insertion opening 2a.
4, the shutter 102 is opened.

Thereafter, the solenoid 11 is energized to rotate the mode lever 14, and the transmission gear 15 and the switching gear 1 are rotated.
7 is disengaged, and at the same time, the transmission gear 16 meshes with the transmission gear 47. The driving force is transmitted to the raising / lowering drive arm 40 shown in FIG. 12 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 bring the disc cartridge 101 to a predetermined position. Positioned. After that, the locked state by the mechanical lock mechanism is released, the traverse chassis 31 is floated by the dampers 34, 35 together with the disc cartridge 101 and the elevating base 6, and the state becomes reproducible.

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. As described above, according to the configuration of this embodiment, the stocker 4 is driven in association with the operation of rotating the rotating panel 1, and the stocker 4 is locked to the housing 3 in the opened state. This facilitates the attachment / detachment operation of the disc cartridge 101, and prevents the rotating panel 1 from being accidentally closed even if the stocker 4 is pushed during attachment. 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, even if the disc cartridge 101 is hit from the outside, the strength is sufficient. You can get it without damaging it.

Further, the disk cartridge 101 mounted in the stocker 4 and the independent insertion slot 2a is driven by one motor 9, and the drive operation is switched by the transport operation of the disk cartridge 101, and one shutter opener 24 and shutter closer 25 are provided. Since the shutters 102 of the plurality of disk cartridges 101 are opened and closed by the above method, the configuration can be simplified as compared with the case where the shutter opening / closing members are provided in the plurality of storage portions having different storage positions and the transport mechanisms are independently configured. it can. 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 constructed 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.

As is clear from the description of the above embodiment,
In the disc playing device of the present invention, by providing an independent insertion port separately from the storage shelf, one disc cartridge other than the disc cartridge mounted on the storage rack can be directly mounted / replaced. When exchanging one piece, it is possible to give a feeling of a one-piece playing device.

Further, in the storage rack, the disc cartridges can be immediately mounted / replaced by opening the rotating panel, so that a plurality of disc cartridges can be exchanged easily and without the trouble of the operator. Can be done.

Since the cartridge transfer means can transfer the disk cartridge from the storage shelf and the independent insertion opening to the playing means, compared to the case where independent transfer means are provided for the storage shelf and the independent insertion opening, respectively. The configuration can be simplified and the device can be downsized.

Further, by providing the rotating panel with the lock means and the lock control means, the rotating panel in the closed state can be restricted from rotating while the disk cartridge is being played from the storage rack. It is possible to prevent double insertion of the disc cartridge into the empty space of the storage shelf after the inner disc cartridge is pulled out.
