When it is slid in the direction of arrow O in FIG.
9 rotates one step in the direction of arrow M to enter the chucking state.

When the rotation slider 55 is continuously slid in the direction of the arrow O, the holder 43 is further rotated one step in the direction of the arrow M.
9 rotates non-simultaneously and is rotated to a desired position.

At this time, the drive unit 49 is connected to the holder 43.
On the other hand, it is located one step lower in the direction of arrow N. In other words, it is a position that is not chucked.

When the holder 43 is rotated to a desired position for the disc cartridge 1, the transfer hook 47 is brought into a state in which it can be engaged with the protrusion 14C of the carrier 13 corresponding to the insertion opening 30A, as shown in FIG. Become. In this state, the transfer driving unit 48 drives the transfer hook 47, so that the disk cartridge 1 starts to be transferred together with the carrier 13 toward the holder 43 side.

That is, the carrier 13 loaded with the disc cartridge 1 is transferred to the slits 43C and 43D of the holder 43 according to the curved guide slits 28A and 29A shown in FIGS.

When the transfer operation of the disc cartridge 1 held by the carrier 13 is completed, the first posture guide portions 23B and 23C slide into the recess 43E, and the second posture guide portion 14B slides into the recess 43G.

Thereafter, the rotary slider 55 is moved to the rotary drive unit 5.
6 slides in the direction of arrow O, and the drive unit 49 rotates one step in the direction of arrow M. As the drive portion 49 rotates, the pressing portions 52E and 52F of the hold plate 52 also rotate about the axis 53 in the arrow N direction.

As a result, the pressing portions 52E and 52F press the disk cartridge 1 toward the drive section 49 via the carrier 13, and the drive section 49 chucks the disk cartridge 1.

In this state, the first posture guide parts 23B, 2
3C and the second posture guide portions 14A and 14B are concave portions 43.
The carrier 13 becomes a free state apart from E, 43F, 43G and the slits 43C, 43D.

After that, the disc 3 is rotated by the rotation of the turntable 50, and the pickup 51 records or reproduces information.

Next, the operation of returning the disc cartridge 1 held by the carrier 13 to the storage section 32,
Since the above-described operation up to recording or reproducing information on the disc cartridge 1 is simply performed in reverse, detailed description thereof will be omitted here.

The operation of ejecting only the disk cartridge 1 from the carrier 13 accommodated in the accommodating portion 32 to the outside of the apparatus will be described. Here, a case where the user gives an instruction to eject the disc cartridge 1 inserted from the insertion port 30C to the outside of the apparatus will be described as an example.

As shown in FIGS. 5 and 6, after the user's instruction, the selecting member 38 moves the selector 37 to the position corresponding to the convex portion 33C by the driving force of the driving means 42.

The driving means 42 moves the slide member 36 through the slide protection member 39 and the slide biasing member 40 in the direction of arrow G.
When it is moved in the direction, the sub-slide member 34 to which the lock release member 33 is attached is moved to the sub-slide biasing member 35.
Since it is held in place by the inclined portion 37A, the inclined portion 37A pushes the convex portion 33C in the direction of arrow D.

As a result, the lock release member 33 causes the gap 2 of the slider 23 of the carrier 13 corresponding to the insertion opening 30C.
Enter the 3D, and push the lock release pressing portion 24C in the direction of the arrow D.

In this state, the holding of the disc cartridge 1 in the carrier 13 is released. At the same time, one ends of the holes 36A and 36B come into contact with the convex portions 34B and 34C,
The driving means 42 further moves the slide member 36 in the direction of arrow G, whereby the holding of the sub-slide member 34 by the sub-slide biasing member 35 is released.

Further, when the slide member 36 is moved in the direction of the arrow G by the driving means 42, the lock releasing member 33 pushed in the direction of the arrow D causes the first posture guide portion 2 to move.
3B is moved in the direction of arrow B.

The fact that the first attitude guide portion 23B moves in the arrow B direction means that the slider 23 moves in the arrow B direction, and therefore the convex portion 23A presses the bent portion 21A in the arrow B direction.

As a result, the ejection lever 21 rotates about the shaft 22 and the disc cartridge 1 is ejected from the insertion port 30C by a predetermined distance. At this time, since the closer 26A (see FIGS. 1 and 2) is engaged with the engagement hole 6, the shutter 5 closes the opening 4 when the ejecting operation of the disc cartridge 1 is completed.

When the ejection of the disc cartridge 1 is completed, the driving means 42 starts moving the slide member 36 in the direction of arrow H in FIGS. Sub slide urging member 35
Since the protruding portion 35A of the sub-sliding member 34 is engaged with the inclined surface 34D, the sub-slide biasing member 34 is held in place without moving in the direction of the arrow H.

When the slide member 36 moves in the direction of arrow H in this state, the convex portion 33C separates from the inclined portion 37A, so that the lock release member 33 swings in the direction of arrow C and comes out of the gap 23D. At the same time, the other ends of the holes 36A and 36B come into contact with the convex portions 34B and 34C, and the holding of the sub slide member 34 by the sub slide biasing member 35 is released.

When the driving means 42 further moves the slide member 36 in the direction of the arrow H, the discharging means 41 returns to its original position, and the slope 34E of the sub-slide member 34 is brought into contact with the projection 35A of the sub-slide biasing member 35. By engaging, the sub-slide member 34 is held in place again.
This completes the discharging operation.

Next, a description will be given of the operation in the case where the ejection operation is obstructed during the ejection operation, for example, by holding down the disk cartridge 1.

In the discharging operation described above, the rotation of the discharging lever 21 causes the disk cartridge 1 to be discharged to the outside of the apparatus. However, if the disk cartridge 1 is suppressed and the discharging is hindered, the discharging lever 21, the slider 23, and the unlocking member. The operations of 33, the sub-slide member 34, and the slide member 36 are suppressed.

Even in that case, since the driving means 42 tries to move the slide member 36 by a certain distance, the slide protection member 39 on the slide member 36 is contrary to the urging force of the slide urging member 40, as shown in FIG. It moves in the direction of arrow G in FIG. During this time, the operations of the ejection lever 21, the slider 23, the lock release member 33, the sub-slide member 34, and the slide member 36 are still suppressed.

When the drive means 42 moves the slide protection member 39 by a certain distance, the drive means 42 moves the slide protection member 39 in the direction of arrow H. Slide protection member 3
When 9 reaches the original position on the slide member 36, the slide member 36 also starts moving in the direction of arrow H.

In the sub-slide member 34, the projection 35A is not engaged with the slope 34D, but the sub-slide biasing member 35 uses the sub-slide member 34 as the selector 37.
Since it is pressed in the direction, the sub-slide biasing member is held in place.

When the driving means 42 further moves the slide member 36 in the direction of arrow H in FIGS. 5 and 6, the convex portion 33C is separated from the inclined portion 37A, and the other ends of the holes 36A and 36B are convex portions 34B and 34C. Abutting against the sub-slide member 3
4 also moves in the direction of arrow H. By this, the discharging means 41 returns to the original position, and the operation when the discharging operation is obstructed is completed.

As described above, according to this embodiment,
When the disc cartridge 1 is held in the carrier 13, the ejection lever 21 does not push the disc cartridge 1, and the pushing portions 26B and 26C of the shutter opening / closing member 26 are pushed.
Pushes the disk cartridge 1 against the slide guides 18 and 19 of the carrier 13,
Unlike the conventional example, the attitude of the disk cassette is not held obliquely in the disk tray, and the disk cartridge 1 can be held straight in the carrier 13. In addition, the engaging portion between the ejection lever 21 and the slider 23 is bent to the bent portion 21A and the convex portion 23A, that is, the ejection lever 2
Since the distance between the shaft 22 and the position of about half of the total length of 1 is large, the amount of movement of the tip of the ejection lever 21 is large even with a small sliding distance of the slider 23. Therefore, the disc cartridge 1 should be ejected sufficiently from the apparatus. You can

Further, since the ejecting means 41 electrically operates the slider 23 by the driving means 42, unlike the conventional example, the disc cassette is not ejected out of the apparatus by the elastic restoring force of the eject spring, and the disc cartridge is not ejected. 1 can be discharged to the outside of the device with good quality.

Further, since the lock release member 33 pushes the lock release pusher 24D swingable in the gap 23D to move the slider 23, the lock release member 33 and the lock other than the guide slit 28A of the chassis L28 are moved. It is possible to simplify the shape of the chassis L28 without forming a slit for the release pressing portion 24D on the chassis L28. Further, since the cartridge presence / absence detecting portion 24A is formed in the lock member 24, the lock member 24 holds the disk cartridge 1 in the carrier 13 at the same time without adding a dedicated component for operating the switch 27. The presence or absence of the disk cartridge 1 in the carrier 13 can be determined by operating the.

Further, the slide protection member 39 and the slide biasing member 40 are attached on the slide member 36, and when a load operation is applied, the slide protection member 39 is moved on the slide member 36.
Slides against the bias of the slide biasing member 40,
Even if the ejection operation is hindered by holding down the disc cartridge 1 during ejection of the disc cartridge 1, the device is not burdened and the device can be prevented from being damaged.

Further, the path from the storage section 32 to the holder 43 is unified, and the transfer guide section 14 becomes the guide slit 2.
The horizontal direction of the carrier 13 is guided with respect to 9A, and the second
Posture guide parts 14A and 14B are guide slits 29A.
Guide the carrier 13 in the vertical direction,
Since the first posture guide portions 23B and 23C and the second posture guide portions 14A and 14B are tapered, the first posture guide portions 23B and 23C and the second posture guide portion 14 are formed.
When A and 14B are transferred from the guide slits 28A and 29A to the slits 43C and 43D, there is no catching or rattling, and the A and 14B are smoothly transferred, so that a desired disc cartridge 1 is selected and information recording or reproducing is started. It is possible to shorten the time until it is done.

Since the rotation axis of the hold plate 52 is different from the axis 43 which is the rotation axis of the holder and the return urging portion 52G is formed on the hold plate 52 itself, the rotation of the drive portion 49 is reduced. Even at the corners, the pressing portions 52E and 52F rotate sufficiently, and a reliable chucking or chucking release operation can be performed with a simpler configuration.

The pressing portions 52E and 52F press the carrier 13 immediately before the chucking is completed, or press the carrier 13 only immediately after the chucking is released. In the chucking state, the pressing portions 52E and 52F are the carrier. In the chucking state, the first posture guide portions 23B and 23C and the second posture guide portions 14A and 14B are pressed against the disc cartridge 1 via the slits 43C,
Since the recesses 43E, 43F, and 43G are formed so as not to contact the 43D, rattling noise of the carrier 13 and the like does not occur, and the chucking noise can be reduced.

[0110]

According to the disk recording / reproducing apparatus of the present invention, the following effects can be obtained.

(1) When the disc cartridge is held in the holding member, the ejection lever does not press the disc cartridge, and the shutter opening / closing member presses the disc cartridge against the slide guide member. The disk cartridge can be held straight in the holding member without being held obliquely. (2) Further, since the engaging portion between the ejection lever and the slider is provided between the position approximately half of the entire length of the ejection lever and the rotation fulcrum, the movement amount of the tip of the ejection lever increases even if the slider has a small sliding distance. Therefore, the disc cartridge can be sufficiently discharged to the outside of the device.

(3) Since the slider is electrically operated by the ejecting means, the disc cartridge can be ejected to the outside of the device with good quality without being ejected to the outside of the device vigorously.

(4) Since the lock release member pushes the lock member swingable within the gap of the first posture guide portion to move the slider, the lock member and the lock release member other than the guide slit are used. The shape of the device can be simplified without forming a slit. (5) Since the cartridge presence / absence detection unit is formed in the lock member, the lock member holds the disc cartridge in the holding member and activates the detection unit at the same time without adding a dedicated component for operating the detection unit. The presence / absence of the disk cartridge in the holding member can be determined.

(6) A slide protection member and a slide biasing member are mounted on the slide member, and when an operation load is applied, the slide protection member slides on the slide member against the bias of the slide biasing member. Even if the ejection operation is hindered by holding down the disk cartridge during ejection of the cartridge, the apparatus itself is not burdened and the apparatus can be prevented from being damaged.

(7) The path from the storage section to the disk cartridge storage section is unified, the transfer guide section guides the holding member in the horizontal direction with respect to the guide slit, and the second posture guide section serves as the guide slit. On the other hand, the first posture guide portion and the second posture guide portion are formed into a tapered shape while guiding the holding member in the vertical direction, and the first posture guide portion and the second posture guide portion are slit from the guide slit. Since there is no catching or rattling at the time of transfer, and the transfer is smooth, it is possible to shorten the time until the desired disk cartridge is selected and the recording or reproduction of information is started.

(8) Since the rotation axis of the pressing biasing means is different from the axis which is the rotation axis of the holder and the return biasing portion is formed in the pressing biasing means itself, the pressing biasing means is The drive unit can be rotated sufficiently even with a small rotation angle, and a reliable chucking or chucking release operation can be performed with a simpler configuration.

(9) The pressing biasing member presses the holding member immediately before the chucking is completed, or presses the holding member only immediately after the chucking is released, and in the chucking state, the pressing biasing member holds the holding member. The disc cartridge is pressed via the, and the concave portion is formed so that the first posture guide portion and the second posture guide portion do not come into contact with the slit in the chucking state, so that there is no rattling noise of the holding member and the like.
The chucking sound can be reduced.
