A fall prevention jii, 27d is provided to prevent the clamp member 27 from falling by being supported on the upper surface of the clamp member 25.

As shown in FIG. 2, guide grooves 5a, 5a are formed at both ends of the tray 5, and the guide grooves 5a, 5a are connected to the side plate 6.
- It is slidably fitted into the guide pieces 6b and 7h provided on the inner upper part of 7, respectively.

Thereby, the tray 5 is able to freely move back and forth in the E and F directions with respect to the chassis 1 between the carry-out position and the carry-in position.

A horizontal fulcrum shaft 6c is provided inside the side plate 6, and a boot TJ 28 is fitted onto the fulcrum shaft 6c. A spring 30 and a washer 31 are further attached to the fulcrum shaft 6C inside the pulley 28, and are prevented from coming off by an E-ring 32. The pulley 28 is rotatable with a predetermined load due to the biasing force of the spring 30.

One end of a carry-out spring 33 serving as a first elastic biasing means is locked to the spring hook 1d of the chassis 1, and the carry-out spring 33
wraps around the outer periphery of the pulley 28 and changes direction to form a substantially U-shape, and the other end of the spring hook provided on the tray 5 is locked to the bin 5b. The tray 5 is urged in the E direction by the unloading spring 33. As mentioned above, the unloading spring 33 has a U-shape by passing through the pulley 28, so it is possible to use a long free length for the unloading spring 33 to lower the spring constant. can. Therefore, the operating force required to manually operate the tray 5 in the F direction against the biasing force of the unloading spring 33 can be sufficiently reduced.

Moreover, since the spring 33 for carrying out is wound around the pulley 28 loaded by the spring 30, the spring 33 for carrying out
The expansion and contraction of is damped by a pulley 28 which functions as a damper. As a result, the movement of the tray 5 in the E direction based on the biasing force of the unloading spring 33 also becomes gentle. In addition, a screw 34 that can engage the spring hook of the tray 5 with the bin 5b is screwed into the screw hole 6d of the side plate 6 so as to protrude inside the side plate 6, so that the tray 5 can be moved by a predetermined stroke E. When the tray 5 moves in the E direction, the spring hook engages the screw 34 with the bin 5b, thereby limiting the amount of movement of the tray 5 in the E direction.

The tray 5 is provided with an escape hole 5C for passing the turntable 23, optical pickup 24, etc. of the CD drive mechanism 3 that rises at the loading position. This escape hole 5
A storage portion 5d for storing the CD2 is provided around the CD2, and the storage portion 5d is formed to be slightly thicker than the outer shape of the CD2.

Further, an inclined receiving part 5e is formed around the storage part 5d as a disc mounting part for receiving the lower part of the CD 2.

Furthermore, on both sides of the receiving part 5e, notches 5 are provided at both ends of the tray 5 to avoid interference between the CD 2 and the side walls of the tray 5, and to facilitate loading and unloading of the CD 2.
[・5r is provided. Further, the inner walls of the side plates 6 and 7 facing the notches 5f and 5r at the loading position of the tray 5 are provided with notches 6e and 7 to avoid interference between the CD 2 and the side plates 6 and 7 while the CD 2 is rotating. 71 is formed.

A spring 35 is inserted above the first lock lever 16 in the fulcrum bin 1e, and a second lock lever 36 as a 20th hook means is rotatably inserted above the spring 35 at the insertion hole 36a. E-ring 37 prevents it from coming off. The spring 35 is tensioned between the spring hook 16e of the first lock lever 16 and the spring hook 36b of the second lock lever 36, thereby biasing the second lock lever 36 in the direction of arrow B. The second lock lever 36 is an abutting portion 36 having a role as a mouth/tuck and a lock release operation portion in the disc player according to claim 1.
c is a spring hook 16e of the first lock lever 16, which also serves as the locking and unlocking operation section.
By coming into contact with , the amount of rotation in the B direction is restricted.

The second lock lever 36 is provided with a lock portion 36d,
The lock portion 36d holds the tray 5 at the loading position by engaging with a long groove 5h formed in the right side wall 5g of the tray 5 when the tray 5 is at the loading position.

In the above configuration, as shown in FIGS. 2 to 4, when the tray 5 is being carried out, the spring hook of the tray 5 is caused by the bin 5b coming into contact with the screw 34, as described above. , is held at the unloading position against the biasing force of the unloading spring 33.

At this unloading position, the elevating member 4 is moved to the first lock lever 16
When the engaging portion 16c engages with the locking portion 4h,
It is located at the end in the F direction against the biasing force of the spring 8.

Therefore, the CD drive mechanism 3 is held in the lowered position in the J direction by positioning each regulation bottle 3a in the release recess 4d. Therefore, the turntable 23 and the optical pickup 24 on the CD drive mechanism 3 are also in the lowered position, and even if the tray 5 moves in the F direction and the CD 2 is carried in, the turntable 23 and the optical pickup 24 are in the F direction.
It is designed so that it does not come into contact with the CD2 that is moving in the direction.

In addition, in the lowered position of the CD drive mechanism 3, only the chucking spring I8 is in a bent state, and the vibration isolating rubber 20 is lowered together with the CD drive mechanism 3, and is not deformed and simply drives the CD. It is placed on mechanism 3,
No unnecessary force is acting on the vibration isolating rubber 20.

Further, the clamp member 27 is lowered by its own weight so that the fall prevention plate 27d is in contact with the upper surface of the base frame 25, but even if the CD 2 is carried in by the tray 5 in this state,
The holding part 27a of the clamp member 27 is moved in the F direction.
It is designed not to come into contact with D2.

In the above-described unloading state, the CD 2 is placed on the receiving portion 5e of the tray 5, and the tray 5 is manually pressed in the direction of arrow F against the biasing force of the unloading spring 33. It is moved from the unloading position shown in the figure to the loading position shown in FIGS. 5 to 7. Then, slightly before the end of the movement stroke of the tray 5, the end surface 51 of the tray 5 is brought into contact with the contact portion 1 of the first lock lever 16.
6d, and as the tray 5 moves in the F direction, the first
The lock lever 16 rotates in the direction of arrow B against the urging force of the spring 17.

By the way, although the second lock lever 36 is biased in the B direction by the spring 35, the contact portion 36C abuts against the spring catch 16e of the first lock lever 16, thereby normally preventing rotation in the B direction. However, as mentioned above,
When the first lock lever 16 rotates in the B direction, it becomes possible to rotate in the B direction accordingly. Then, when the movement stroke of the tray 5 in the F direction is almost completed and the second lock lever 36 can be rotated in the B direction, the lock part 36d is located slightly behind the locking groove part 5h of the tray 5. Since the second lock lever 3 is in contact with the side wall 5g near the
6 does not immediately rotate in the B direction, but when the tray 5 finishes moving in the F direction and reaches the loading position, the second lock lever 36 rotates in the B direction due to the biasing force of the spring 35. The locking portion 36d fits into the locking groove 5h of the tray 5,
The tray 5 is locked at the loading position.

Additionally, as the first lock lever 16 rotates in the B direction,
The engaging portion 16c disengages from the lock portion 4h of the elevating member 4 and engages with the abutting portion 41, and at this point the first lock lever 16
The rotation in direction B is completed. Then, when the engaging part 16c disengages from the locking part 4h, the holding state of the lifting member 4 at the moving end in the F direction by the first lock lever 16 is released, so that the lifting member 4 is moved by the spring 8. It begins to move in the E direction due to the urging force.

As the elevating member 4 moves in the E direction, each regulation bin 3a of the CD drive mechanism 3 moves into the releasing recess 4d of the elevating member 4.
From there, it moves to the inclined recess 4e, and further moves within the inclined recess 4e toward the regulating recess 4c. As a result, the CD drive mechanism 3 moves upward within the escape hole 5C of the tray 5, that is, in the {circle around (2)} direction by the urging force of the chucking spring 18. In this case, since the rack 13 provided on the elevating member 4 meshes with the gear 14a of the damper member 14, the elevating member 4 moves slowly in the E direction, and therefore the CD drive mechanism 3 Movement in this direction is also gradual.

As the CD drive mechanism 3 moves in the direction {circle around (2)}, the slope part 23b of the turntable 23 first engages with the chucking hole 2a of the CD 2, and when the CD drive mechanism 3 further moves up, the slope part 23b engages with the chucking hole 2a of the CD 2. Slanted recess 2 of clamp member 27
7b, and the CD 2 is chaffed by the attraction force between the magnet 27c and the attraction plate 23c. In addition, CD2
FIG. 7 shows the chucking state with the chucking state omitted. after that,
When the CD drive mechanism 3 further rises, the fall prevention plate 27d separates from the base frame 25, and a gap is formed between the fall prevention plate 27d and the base frame 25. In this state, the regulation pin 3a of the CD drive mechanism 3 fits into the regulation recess 4C, and reaches the highest position.

CD drive machine fl! 13 reaches the highest position, the washer 21 and the anti-vibration rubber 20 come into contact with the E-ring 22, the chucking spring 18 is expanded, the anti-vibration rubber 20 is slightly deformed, and the clamp member 27 is in contact with the washer 21 and the anti-vibration rubber 20. CD2 between
The CD drive mechanism 3 that has been chucked is floated independently from the chassis 1 etc. by the chucking spring 18 and the vibration isolating rubber 20. This provides vibration resistance against external vibrations that may occur in the chassis 1 and the like. Here, the relative vibration of the CD drive mechanism 3 with respect to the chassis 1 etc. occurs within the range of the gap between the regulation bottle 9a and the regulation recess 4C and the gap between the regulation hole 3C and the regulation bottle IC. In addition, while rotating the CD 2 with the turntable 23 in the above-mentioned floating state,
The optical pickup 24 reads the signals on the CD 2.

As described above, when a CD 2 is mounted on the tray 5 and loaded by manually moving the tray 5 in the F direction, the CD drive mechanism 3 holding the CD 2 floats independently from the chassis 1 etc., and the vibration resistance is improved. will have. Furthermore, when the CD drive mechanism 3 is in the lowered position, only the chucking spring 18 is bent to avoid unnecessary deformation of the vibration isolating rubber 20, so that the life of the vibration isolating rubber 20 can be extended. .

Furthermore, when the tray 5 is moved to the carry-in position, the elevating member 4 automatically moves in the E direction to cause the CD drive mechanism 3 and the clamp member 27 to chuff the CD 2, making the operation easy. It is.

Furthermore, when the first lock lever 16 begins to rotate in the B direction as the tray 5 moves in the F direction, the second lock lever 36 is enabled to rotate in the B direction by the spring 35, Since the lock part 36d of the second lock lever 36 is pressed against the side wall part 5g of the tray 5 before it reaches the locking groove part 5h of the tray 5, the tray 5 can be carried in by the second lock lever 36. Locking in position is ensured.

Further, as described above, the movement of the lifting member 4 in the E direction is performed gently by being damped by the damper member 14, and therefore,
Since the CD drive mechanism 3 is also raised slowly, the CD2
The CD 2 is not damaged by the turntable 23 during chucking, and the noise during loading can be reduced.

Next, the operation when moving the tray 5 from the carry-in position to the carry-out position will be explained.

To carry out the tray 5 from the state shown in FIGS. 5 to 7,
When the operating part 11b of the unloading operating lever 11 is pressed in the direction of the arrow, the elevating member 4 that is in contact with the pressing part LIC of the unloading operating lever 11 comes into contact with the CD drive mechanism 3 in the raised state. The portion 4g is pressed in the F direction by the pressing portion 11c, and thereby the elevating member 4 moves in the F direction against the biasing force of the spring 8.

Then, each regulation bin 3a of the CD drive mechanism 3 moves from the regulation recess 4C of the elevating member 4 to the release recess 4d via the inclined recess 4e, and the CD drive mechanism 3 moves downward, that is, by the arrow J. move in the direction. CD drive mechanism 3
As the turntable 23 moves in the J direction, the drop prevention plate 27d of the clamp member 27 comes into contact with the upper surface of the base frame 25, and the chucking of the CD 2 due to the magnetic force between the turntable 23 and the clamp member 27 is released. When the CD drive mechanism 3 further moves in the J direction, the CD 2 comes into contact with the receiving part 5e of the tray 5,
The CD 2 and the turntable 23 are disengaged from each other and reach the lowest position.

When the lifting member 4 moves to the end in the F direction, 91
When the first lock lever 16 is rotated in the entry direction by the urging force of 7, the engaging portion 16c that has been engaged with the contact portion 41 of the lifting member 4 engages with the locking portion 4h, and this According to
The lifting member 4 is locked at the end in the force <F direction. In other words, the CD drive mechanism 3 is locked at the lowest position.

Further, as described above, the second lock lever 36 is connected to the contact portion 36.
c is in contact with the spring hook 16e of the first lock lever 16, and as the first lock lever 16 rotates in the A direction, the second lock lever 36 also rotates in the inward direction, so that the lock portion 36d is removed from the locking groove 5h of the tray 5, and the tray 5 is unlocked at the carry-in position. As a result, the tray 5 moves in the E direction together with the CD 2 due to the biasing force of the unloading spring 33, and the CD 2 is unloaded. Here, as mentioned above, the contraction of the unloading spring 33 is carried out gently, being buffered by the pulley 28, and therefore the tray 5 is also slowly unloaded.

Also, to remove the CD2, lower the CD drive mechanism 3 and remove the CD2.
Since the CD 2 is carried out in a non-contact state, the CD 2 is not damaged during the carrying out, and moreover, the CD 2 can be carried out simply by operating the carrying out operation lever 11.

(Effect of the invention) As described above, the disc player according to the invention of claim 1 in the claims column of this specification has a player main body and a disc mounting section, and is unloadable by the player main body. a movable member supported movably between the loading position and the loading position and biased toward the loading position by the first elastic biasing means, and capable of driving the disk and reading information on the disk; , is supported by the player main body so as to be movable between a lowered position, which is a non-engaging position with the disc, and a raised position, which is an engaged position with the disc, and a second
The disk drive mechanism biased toward the raised position by the elastic biasing means, the first locking member that locks the disc drive mechanism at the lowered position, the second locking member that locks the moving member at the loading position, and the moving member. A lock and lock release operation unit that allows the first lock member to unlock the disk drive mechanism and the second lock member to lock the movable member in conjunction with each other as the member moves to the loading position. This is a configuration where there is

As a result, when a disk is placed on the disk placement section of the moving member at the unloading position and the moving member of the disk placement section is manually moved to the loading position, the disk is moved by the action of the locking and unlocking operation section. The member is locked at the loading position by the second locking member, and the disc drive mechanism is unlocked at the lowered position by the first locking member, so that the disc drive mechanism is activated by the biasing force of the second elastic biasing means. The disk drive mechanism is moved to a raised position to engage the disk. In this way, a manual disc player is provided in which discs can be easily loaded simply by manually pushing the moving member into the loading position.

Further, the disc player according to the invention of claim 2 has a player main body and a disc mounting part, and is movably supported by the player main body between an unloading position and a loading position, and has a first elastic member. a moving member urged toward the ejecting position by a biasing means; a lowering position F, which is a position in which the disc can be driven and information on the disc is read; and the disc is not engaged with the disc by the player body; The disk drive mechanism is movably supported between a raised position, which is an engagement position with the moving member, and is biased toward the raised position by a second elastic biasing means, and when the moving member is in the unloading position, the disc a first +J vine member that locks and holds the drive mechanism in the lowered position and unlocks the disk drive mechanism as the movable member moves to the carry-in position; In addition, when the first locking member locks the disk drive mechanism, the first locking member prevents the locking operation, while the second locking member allows the locking operation when the first locking member is unlocked.
This configuration includes a lock member.

As a result, when a disk is placed on the disk mounting portion of the movable member at the unloading position and the movable member with the disk mounted thereon is manually moved to the loading position, the first By releasing the lock of the disk drive mechanism in the lowered position by the locking member, the disk drive mechanism is moved to the raised position by the second elastic biasing means, and the disk drive mechanism engages with the disk. As the first locking member is unlocked, cocking of the twentieth vine member is permitted, so the second locking member locks the movable member at the carry-in position.

In this way, similarly to the first aspect, a manual disc player with excellent operability is provided in which loading of a disc can be completed simply by manually pushing the moving member into the loading position.
