A spring 35 is inserted above the first lock lever 16 at the fulcrum pin 1e, and a second lock lever 36 as a second lock means is rotatably inserted above the spring 35 at a portion of an insertion hole 36a. The E-ring 37 prevents it from coming off. The spring 35 is stretched between the spring hook 16e of the first lock lever 16 and the spring hook 36b of the second lock lever 36, whereby the second lock lever 36 is biased in the arrow B direction. Second lock lever 36
Is an abutting portion 36 having a role as a lock and unlock operation portion in the disc player according to claim 1.
c is a spring hook 16e of the first lock lever 16 which also functions as the lock and unlock operation section.
The amount of rotation in the B direction is regulated by abutting against.

The second lock lever 36 is provided with a lock portion 36d,
The lock portion 36d is adapted to hold the tray 5 at the carry-in position by engaging with the tray groove 5h formed on the right side wall portion 5g of the tray 5 when the tray 5 is at the carry-in position.

In the above-described configuration, as shown in FIGS. 2 to 4, when the tray 5 is being carried out, the tray 5 causes the spring hooking pin 5b to come into contact with the saw screw 34, as described above. It is held at the carry-out position against the biasing force of the carry-out spring 33.

At this unloading position, the elevating member 4 has the first lock lever 16
By engaging the engaging portion 16c of 4 with the lock 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 which is lowered in the J direction due to the restriction pins 3a being positioned inside 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 loaded, the turntable 23 and the optical pickup 24 move to the F position.
It does not come into contact with the CD2 moving in the direction.

Further, when the CD drive mechanism 3 is in the lowered position, only the chucking spring 18 is bent, and the anti-vibration rubber 20 moves down together with the CD drive mechanism 3 and is not deformed. It is placed on the mechanism 3,
Unnecessary force does not act on the antivibration rubber 20.

Further, although the clamp member 27 is lowered by its own weight and the fall prevention plate 27d is in contact with the upper surface of the base frame 25, even if the CD 2 is carried in by the tray 5 in this state,
The holding portion 27a of the clamp member 27 is C moving in the F direction.
It does not touch D2.

In the unloading state described above, 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 urging force of the unloading spring 33, as shown in FIGS. It is moved from the carry-out position shown in the figure to the carry-in position shown in FIGS. Then, the end face 5i of the tray 5 is slightly abutted with the abutting portion 1 of the first lock lever 16 when the moving stroke of the tray 5 is completed.
6d, the first with the movement of the tray 5 in the F direction
The lock lever 16 rotates in the direction of arrow B against the biasing 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 normally contacts the spring hook 16e of the first lock lever 16 to prevent the rotation in the B direction. But 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 portion 36d is slightly behind the locking groove portion 5h of the tray 5. Since it is in contact with the side wall portion 5g near the second lock lever 3,
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 by the urging force of the spring 35, The lock portion 36d fits into the lock groove portion 5h of the tray 5,
The tray 5 is locked at the loading position.

Further, with the rotation of the first lock lever 16 in the B direction,
The engaging portion 16c disengages from the lock portion 4h of the elevating member 4 and engages with the contact portion 4i. At this point, the first lock lever 16
The rotation in the direction B ends. When the engaging portion 16c is disengaged from the lock portion 4h, the holding state at the moving end of the elevating member 4 in the F direction by the first lock lever 16 is released. It starts moving in the E direction due to the urging force.

As the elevating member 4 moves in the E direction, the restriction pins 3a of the CD drive mechanism 3 cause the releasing recess 4d of the elevating member 4 to be released.
To the inclined concave portion 4e, and further to the regulating concave portion 4c side in the inclined concave portion 4e. As a result, the CD drive mechanism 3 moves upward, that is, in one direction in the escape hole 5c of the tray 5 by the biasing force of the chucking spring 18. In that case, the rack 13 provided on the elevating member 4 is replaced by the damper member 14
Since it is meshed with the gear 14a of the CD drive mechanism 3, the elevating member 4 moves slowly in the E direction.
Is slowly moved in the I direction.

With the movement of the CD drive mechanism 3 in the direction I, the slope portion 23b of the turntable 23 first engages with the chucking hole 2a of the CD 2, and when the CD drive mechanism 3 further rises, the slope portion 23b Inclined concave portion 2 of clamp member 27
CD2 is chucked by the attraction force between the magnet 27c and the attraction plate 23c by engaging with 7b. In addition, CD2
FIG. 7 shows a chucking state in which is omitted. afterwards,
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, in the CD drive mechanism 3, the regulation pin 3a fits into the regulation recess 4c and reaches the highest position.

When the CD drive mechanism 3 reaches the highest position, the washer 21 and the vibration isolating rubber 20 come into contact with the E ring 22, the chucking spring 18 extends, and the vibration isolating rubber 20 is slightly deformed. The CD drive mechanism 3 chucking the CD 2 with the chuck 27 is the chucking spring 18
Also, the anti-vibration rubber 20 floats independently of the chassis 1 and the like. As a result, vibration resistance performance against external vibration that may occur in the chassis 1 and the like is imparted.
Here, the relative vibration of the CD drive mechanism 3 with respect to the chassis 1 and the like occurs within the range of the clearance between the restriction pin 3a and the restriction recess 4c and the clearance between the restriction hole 3c and the restriction pin 1c. In the above floating state, the optical pickup 24 reads the signal on the CD 2 while the CD 2 is rotated by the turntable 23.

As described above, when the CD 2 is mounted on the tray 5 and the tray 5 is manually moved in the F direction to be loaded, the CD drive mechanism 3 holding the CD 2 floats independently of the chassis 1 and the like, and the vibration resistance performance is improved. Will have. Further, 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. .

Further, when the tray 5 is moved to the carry-in position, the elevating member 4 automatically moves in the E direction to chuck the CD 2 by the CD drive mechanism 3 and the clamp member 27, so that the operation is easy. Is.

Further, when the first lock lever 16 starts to rotate in the B direction with the movement of the tray 5 in the F direction, the second lock lever 36 can be rotated in the B direction by the spring 35. The lock portion 36d of the second lock lever 36 is attached to the tray 5
Since the lock portion 36d is pressed against the side wall portion 5g of the tray 5 before reaching the locking groove portion 5h, the locking of the tray 5 at the carry-in position by the second lock lever 36 is reliably performed.

Further, as described above, the movement of the elevating member 4 in the E direction is buffered by the damper member 14 and is gently performed.
Since the CD drive mechanism 3 is raised gently, the CD2
It is possible to prevent the CD 2 from being damaged by the turntable 23 at the time of chucking and to reduce the noise at the time of loading.

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

To carry out the tray 5 from the state shown in FIGS. 5 to 7,
When the operating portion 11b of the unloading operation lever 11 is pressed in the direction of arrow D, the contact portion 4g of the lifting member 4 that is in contact with the pressing portion 11c of the unloading operation lever 11 when the CD drive mechanism 3 is in the raised state. Is pressed in the F direction by the pressing portion 11c, whereby the elevating member 4 moves in the F direction against the biasing force of the spring 8.

Then, each regulation pin 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 is moved downward, that is, the arrow J. Move in the direction. CD drive mechanism 3
With the movement in the J direction, the fall prevention plate 27d of the clamp member 27 contacts the upper surface of the base frame 25, and the chucking of the CD2 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 portion 5e of the tray 5,
The engagement between the CD 2 and the turntable 23 is released, and the lowest position is reached.

When the lifting member 4 moves to the end in the F direction, the spring 17
When the first lock lever 16 is rotated in the A direction by the urging force of the engaging portion 16c, the engaging portion 16c that was engaged with the contact portion 4i of the elevating member 4 is engaged with the lock portion 4h. The lifting member 4 is locked at the end in the 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 has the contact portion 36.
Since c is in contact with the spring hook 16e of the first lock lever 16, the second lock lever 36 also rotates in the A direction with the rotation of the first lock lever 16 in the A direction. Is released from the lock groove portion 5h of the tray 5, and the lock at the loading position of the tray 5 is released. As a result, the tray 5 is moved to the CD 2 by the urging force of the unloading spring 33.
Therefore, the CD 2 is carried out by moving in the E direction. Here, the contraction of the carry-out spring 33 is as described above.
It is buffered by the pulley 28 and is done gently, thus
The tray 5 is also carried out gently.

The moving member urged to the ejection position side by the urging means enables the disc to be driven and the information on the disc to be read, and the player main body to lower the disc from the lower position which is the non-engagement position with the disc. The disk drive mechanism is movably supported between the engaging position and the ascending position and is urged toward the ascending position by the second elastic urging means, and the disk drive mechanism when the moving member is at the unloading position. It is possible to lock the moving member at the carry-in position and the first lock member that holds the lock at the lowered position and unlocks the disk drive mechanism as the moving member moves to the carry-in position. And the second lock member, whose lock operation is blocked by the first lock member when the disk drive mechanism is locked by the first lock member, and whose lock operation is allowed as the first lock member is unlocked. It is a configuration including and.

As a result, when the disc is placed on the disc placing portion of the moving member at the carry-out position and the moving member having the disc placed thereon is manually moved to the carry-in position, the first member is moved along with the movement of the moving member to the carry-in position. When the lock member releases the lock of the disc drive mechanism at the lowered position, the disc drive mechanism is moved to the raised position by the second elastic biasing means, and the disc drive mechanism engages with the disc. Since the lock operation of the second lock member is allowed as the first lock member is unlocked, the second lock member locks the moving member at the loading position. As described above, similarly to the first aspect of the present invention, a manual disc player with excellent operability is provided in which loading of the disc is completed only by manually pushing the moving member to the loading position.
