Although not shown, the cartridge stopper link 1
At the rear (left side in the figure) of g, there is formed an inwardly raised stop to prevent the cartridge 6 from being inserted any more.

(B) Cartridge The cartridge 6 mounted from the front side of the chassis 1 is configured as follows. That is, as shown in FIG. 3, the cartridge 6 is a box-shaped member provided with an opening 6a on one side (left side in the figure), and has a front inner side (right side in the figure) on its front side. Two plug-like (see FIG. 2) tray springs 6b are provided in two layers in each layer. In addition, a recess 6c corresponding to the raised portion 1f of the cartridge stopper 1e in the chassis 1 is provided on the right (outer side in the figure) outer surface of the cartridge 6.

A plurality of trays 6d are arranged inside the cartridge 6 in a multi-layered manner. Each tray 6d
Is composed of two resin plates, is configured to sandwich the disk 4 with clearance from above and below, and is provided with walls on three sides so that the disk 4 can be taken in and out horizontally only from the opening 6a side. I have. As shown in FIG. 4, a tray hook 6e, which is a crank-shaped notch, is formed at the left end (the lower left end in the figure) of each tray 6d on the opening 6a side. The left and right (upper and lower sides in the figure) inner side surfaces of each tray 6d are provided with leaf springs 6f that are bent inwardly to support the disk 4 from both sides. Further, two socket holes 6g corresponding to the tray spring 6b of the cartridge 6 are provided on the front outer side surface (right side in the figure) of each tray 6d.

The arrangement of the tray 6d in the cartridge 6 and the specific dimensions of the tray 6d are as follows. That is, in the case of a normal disk device, five disks 4 are stored in the cartridge 6 by the tray 6d. The spacing between the recording surfaces of each disk is set to 5.5 mm as shown in FIG. This is because the vertical movement width of the traverse 2 between the floating state and the locked state is 4 mm at the maximum. That is, even when the traverse 2 moves by 4 mm in the transition from the floating state to the locked state or the transition from the locked state to the floating state, the disk 4 chucked on the turntable 3 is not moved. However, this is to prevent the disk 6 from hitting another disk 4 stored in the cartridge 6.

Further, as shown in FIG.
The center of the disk 4 stored in the inside and the turntable 3
The distance from the center of the upper disk 4 is set to 85 mm. This is because the horizontal movement width of the traverse 2 is also a maximum of 4 mm.

The opening 6a side of the tray 6d accommodated in the cartridge 6 is cut out from the center of the disk 4 chucked on the turntable 3 by an arc having a radius of 65 mm. This eliminates the overlap between the disc 4 chucked on the turntable 3 and the tray 6d, and allows the tray 6d to be completely separated from the chucked disc 4 only by moving the tray 6d by 85 mm. This is because The value of the radius of the arc of 65 mm is the radius of the disk of 60 mm.
In addition, the moving range of the traverse 2 is 4 mm and the clearance is added.

Further, since the position corresponding to the center of the disk 4 on the tray 6d is cut out in a round shape, the upper and lower surfaces near the center of the disk 4 are exposed. This is because the disk 4 is chucked with the center portion of the disk 4 sandwiched from above and below while the disk 4 is stored in the tray 6d.

Further, the second slide plate 16 is located behind the chassis 1, and the traverse 2 is also locked by a traverse lock arm (not shown) connected to the second slide plate 16.

(B) At the time of inserting the cartridge Next, the operation of the present embodiment when the cartridge 6 is inserted from the front of the chassis 1 will be described with reference to FIGS. First, the operation of mounting the tray 6d on the cartridge 6 will be described. That is, when the disc 4 is inserted into the tray 6d, the leaf spring 6f in the tray 6d is expanded,
When the disc 4 is further inserted, the leaf spring 6f passes over the diameter of the disc 4, and the disc 4
Is drawn into the tray 6d and stored. In this way, the tray 6 d containing the disk 4 is inserted horizontally from the opening 6 a of the cartridge 6. Then, tray 6
The tray spring 6b of the cartridge 6 is pressed and fitted into the socket hole 6g of d, and the tray 6d is mounted in the cartridge 6.

Next, the operation of inserting the cartridge 6 into the chassis 1 will be described below. That is, when the cartridge 6 is inserted, the end on the opening 6a side of the cartridge 6 comes into contact with the cartridge attack pin 7a of the cartridge attack arm 7, so that the cartridge attack arm 7 rotates backward and escapes. Further, when the cartridge 6 is inserted, the end of the cartridge 6 on the opening 6a side comes into contact with a stop (not shown) provided on the chassis 1, and further insertion is prevented. At this time, the raised portion 1f of the cartridge stopper 1e is
The cartridge 6 is mounted on the chassis 1 because it engages with the recess 6c on the side surface.

(C) Selecting a Disk and Loading a Disk The operation of selecting a predetermined disk 4 from the cartridge 6 and transporting it to the turntable 3 will be described below. That is, the motor is driven to slide the main plate 1a to a desired storage position of the disk 4. Then, the tray hook portion 6e of the tray 6d storing the desired disk 4 and the movable rack hook 13 of the movable rack 13
a engages.

Next, when the drive gear 14 is rotated clockwise in the figure by the mode motor from the standby state in FIG. 7, the gear teeth 9b of the cam gear 9 are engaged with the drive gear 14, so that the cam gear 9 Rotates counterclockwise. Then, as shown in FIG. 14, the connecting arm 10 provided on the cam gear 9 is pulled rearward, so that the moving plate 11 connected to the end of the connecting arm 10 slides rearward. When the moving plate 11 moves backward, the moving gear 12 provided on the moving plate 11 also moves backward. When the moving gear 12 moves backward, the small gear 12a of the moving gear 12 is engaged with the rack provided on the fixed rack 8, and thus rotates clockwise together with the large gear 12b. Since the large gear 12b is engaged with the rack of the movable rack 13, the clockwise rotation of the large gear 12b
The movable rack 13 slides rearward.

At this time, the moving rack hook 13a of the moving rack 13 is connected to the tray 6d containing the desired disk 4.
When the movable rack 13 slides rearward, the tray 6d is pulled out and slides rearward. When the cam gear 4 further rotates counterclockwise, the disk 4 in the tray 4 comes between the turntable 3 and the clamper 5.

(D) At the time of disc chucking Next, the disc 4 is clamped to the clamper 5 and the turntable 3.
A description will be given of a disc chucking operation sandwiched between the two.
That is, when the cam gear 9 is rotated in the counterclockwise direction, the engagement between the gear teeth 9b and the drive gear 14 is released by the notch 9a of the cam gear 9, as shown in FIG. The loading (drawing to the turntable side) of the tray 4 is completed by the substantially half rotation of the cam gear 9.

Further, since the slide pin 15e of the first slide plate 15 moves to the bending portion 9e through the curved portion 9f of the first slide plate cam groove 9d, the first slide plate 15 slides rearward. . When the first slide plate 15 moves backward, the first rack 15 c provided behind the first slide plate 15 engages with the drive gear 14. Therefore, at this time, the drive source of the first slide plate 15 is changed from the cam gear 9 to the drive gear 14, and the clockwise rotation of the drive gear 14 causes the first slide plate 15 to move further backward.

At this time, the first chucking cam 15d in front of the first slide plate 15 moves rearward, and
The front pin 2b of the traverse 2 inserted into the chucking cam 15d moves along the first chucking cam 15d away from the main plate 1a (downward in the figure). Thus, the disc held on the tray 6d is chucked.

When the first slide plate 15 moves rearward, the first rack 15c comes off behind the drive gear 14. At this time, the slide pin 15e moves from the bent portion 9e of the first slide plate cam groove 9d to the outer semicircular portion. Then, since the cam gear 9 is urged by the slide pin 15e, the cam gear 9 rotates counterclockwise, and the gear teeth 9c engage with the drive gear 14. Then, when the cam gear 9 is further rotated substantially half-counterclockwise by the drive gear 14, the engagement between the gear teeth 9c and the drive gear 14 is released by the notch 9a (FIG. 13). The following (e)
As described above, the tray 6d is returned into the cartridge by this half rotation.

At this time, the lower link pin 17b of the link plate 17 engaged with the link plate cam groove 9g of the cam gear 9 comes to the V-shaped portion 9h at the end of the link plate cam groove 9g. Then, when the lower link pin 17b comes into contact with the dogleg 9h, the link plate 17 rotates forward about the pin 5b, so that the upper link pin 17a is inclined forward. Then, the escape portion 16d of the second chucking cam 16c with which the upper link pin 17a is engaged is urged forward, and the second slide plate 16 moves forward. The provided second rack 16 b engages with the drive gear 14.

Therefore, the second drive gear 14
Since the slide plate 16 slides forward,
The upper link pin 17a of the link plate 17 is
d and moves to the rear of the second chucking cam 16c (FIG. 13). When the second slide plate 16 moves forward, the lock of the traverse 2 by the traverse lock arm (not shown) is released.

(E) At the time of playing the disc The work until the playing of the chucked disc 4 will be described below. That is, when the cam gear 9 rotates counterclockwise by the engagement of the gear teeth 9c and the driving gear 14 as described above, the connecting arm 10 moves forward as shown in FIG. Slides forward. Then, the moving gear 12 provided on the moving plate 11 also moves forward,
Since the small gear 12a of the moving gear 12 is engaged with the fixed rack 8, the small gear 12a rotates counterclockwise and the large gear 12a rotates counterclockwise.
