Abstract

PURPOSE:To suppress the deterioration of vibration proof rubber and to make the life thereof long by providing the vibration proof rubber which is sandwiched between a supporting member and a disk driving mechanism being situated at an ascending position and an energizing means which energizes the disk driving mechanism in the ascending position side. CONSTITUTION:When the CD driving mechanism 3 arrives at the most ascending position, a washer 21 and the vibration proof rubber 20 abut on an E ring 22. As the result, a spring for chucking 18 is elongated. Then, under the state the vibration proof rubber is deformed a little, the CD driving mechanism 3 holding a CD 2 between a clamp member 27 and itself becomes independent from a chassis 1 and the like, floats and has vibration proof ability. Besides, when the CD driving mechanism 3 is at a descending position, the unnecessary deformation of the vibration proof rubber 20 is avoided by deflecting only the spring for chucking 18. Thus, the life of the vibration proof rubber 20 can be made long.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc player that chucks a disc by raising and lowering a disc drive mechanism.

[Conventional technology]

In the past, optical playback devices such as compact disc players were positioned as high-end products, and loading and unloading of discs into and out of the device was usually done electrically and automatically in tray-type devices, but in recent years , compact disc players, etc. are becoming popular, and manual devices for manually loading and unloading discs are being developed.

By the way, in such a disc player, when the disc carried in by the tray is engaged with and disengaged from the disc drive mechanism by raising and lowering the disc drive mechanism, at the raised position which is the engagement position with the disc, In order to prevent external vibrations from the player body or the like from being transmitted to the disc drive mechanism, the disc drive mechanism is supported by vibration-proof rubber.

[Problem to be solved by the invention]

However, in the above-mentioned disc player, the anti-vibration rubber is configured to move tQ when the disk drive mechanism is in the lowered position, which is the position where it does not engage with the disc, so the anti-vibration rubber deteriorates early and its life is shortened. The problem was that it caused a decrease in

[Means to solve the problem]

In order to solve the above-mentioned problems, a disc player according to the present invention includes a player body, a disc drive mechanism capable of driving a disc and reading information on the disc, and a disc drive mechanism provided in the player body to drive a disc. Mechanism

A magnet 27C is inserted into the center of the clamp member 27 and holds the CD 2 between the turntable 23 by magnetically attracting the attraction plate 23c of the turntable 23, and a base frame is inserted around the hole 25b. The clamp member 27 is provided with a fall prevention plate 27d that prevents the clamp member 27 from falling by slidingly contacting the upper surface of the clamp member 25.

Guide grooves 5a, 5a are formed at both end portions of the tray 5, and the guide grooves 5a, 5a are slidably fitted into guide pieces 6b, 7h provided on the upper inner sides of the side plates 6, 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 Fi6,
A pulley 28 is fitted onto the fulcrum shaft 6c. Pulley 2
8, a spring 30 and a washer 31 are further attached to the fulcrum shaft 6c, 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 the unloading spring 33 is locked to the spring hook 1d of the chassis 1, and the unloading spring 33 wraps around the outer periphery of the pulley 28 and changes direction to form a substantially U-shape, and the other end is attached to the tray 5. A spring hook provided at is locked to the pin 5b. The tray 5 is urged in the E direction by the unloading spring 33. As mentioned above, since the unloading spring 33 has a U-shape by passing through the pulley 28, the unloading spring 33 can be used with a long free length to lower the spring constant. . 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 spring catch of the tray 5 is screwed into the screw hole 6d of the side plate 6 so that a screw 34 that can engage with the pin 5b protrudes inside the side plate 6, and the tray 5 is moved in the E direction by a predetermined stroke. At the stage when the spring hook is moved to
By engaging with the tray 5, the tray 5 is held at the unloading position.

When the tray 5 is in the carry-in position, the C
An escape hole 5c is provided through which the turntable 23 and optical pickup 24, which move up and down as the D drive mechanism 3 moves up and down, pass through. Around this escape hole 5c, C
A storage section 5d for storing D2 is provided, and the storage section 5
d is formed slightly larger than the outer shape of CD2. Furthermore, an inclined receiving part 5e (see FIG. 4) for receiving the lower part of the CD 2 is formed around the storage part 5d.

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.
f.5f is provided. Further, the inner walls of the side plates 6 and 7 facing the notches 5f and 5f 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 10th lever 16 in the fulcrum pin 1e, and a 20th lever 36 is rotatably inserted above the spring 35 at the insertion hole 36a, and is prevented from coming off by an E ring 37. has been done. spring 35
is the spring hook 16e of the 10th lever 16 and the 20th lever 16.
The 20th lever 36 is stretched between the spring hook 36b of the lever 36, and thereby the 20th lever 36 is biased in the direction of arrow B. The contact portion 36c of the 20th lever 36 is 'M'.
10 The amount of rotation in the B direction is regulated by contacting the spring hook 1.6 e of the lever 16.

The 20th lever 36 is provided with a lock portion 36d,
When the tray 5 is in the carry-in position, the lock part 36d engages with a locking groove 5h formed in the right side wall part 5g of the tray 5 to hold the tray 5 in the carry-in 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. , the tray 5 is held at the unloading position against the biasing force of the unloading spring 33.

At this unloading position, the lifting member 4 is moved to the tenth 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 within the release portion 4d. Therefore, since the turntable 23 and the optical pickup 24 on the CD drive mechanism 3 are also in the lowered position, 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
is arranged so that it does not come into contact with CD2 which is moving in the F direction.

Also, when the CD drive mechanism 3 is in the lowered position, the chucking spring 18 (although it is in a slightly bent state), the vibration isolating rubber 20 is lowered together with the CD drive mechanism 3, and is not deformed. It is placed on the CD drive mechanism 3, and no unnecessary force is applied to the vibration isolating rubber 20.

Furthermore, the clamp member 27 descends due to its own weight, and the drop prevention Fi 27d is brought into 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 part of the clamp member 27 27a does not come into contact with the CD 2 that is moving in the F direction.

In the unloading state described in ``2'', the CD 2 is placed on the receiving portion 5e of the tray 5, and the tray 5 with the CD 2 placed thereon is placed on the unloading spring 33.
arrow l? Press manually in the force direction, and
It is moved from the carry-out position shown in FIGS. 4 to 4 to the carry-in position shown in FIGS. 5 to 7. Then, the end surface 51 of the tray 5 comes into contact with the abutting portion 16d of the tenth lever 16 slightly before the end of the movement stroke of the tray 5, and as the tray 5 moves in the F direction, the tenth lever 16 is moved by the spring 17. It rotates in the direction of arrow B against the urging force of.

By the way, although the 20th Tsukuru lever 36 is biased in the direction B by the spring 35, since the contact portion 36C is in contact with the spring catch 16e of the 10th Tsukuru lever 16, the rotation in the B direction is normally prevented. However, as mentioned above,
When the 10th lever 16 rotates in the B direction, the 20th lever 36 can also rotate in the B direction. When the tray 5 has almost completed its stroke in the direction F, the tray 5 causes the tenth lever 16 to rotate in the direction B.
When the 20th lock lever 36 is allowed to rotate in the B direction, the locking portion 36d is inserted into the locking groove 5 of the 1-lay 5.
Since the tray 5 contacts the side wall 5g at a slightly rearward position of h, the second tl17 lever 36 does not immediately rotate in the B direction, but the tray 5 completes its stroke in the F direction and reaches the loading position. and the 20th lever 36 is connected to the spring 35.
The locking portion 36d is fitted into the locking groove 5h of the tray 5, and the tray 5 is locked at the loading position.

Also, as the tenth vine lever 16 rotates in the B direction,
The engaging portion 16c disengages from the locking portion 4h of the lifting member 4 and engages with the abutting portion 41, and at this point the tenth lever 16
The rotation in direction B is completed. When the engaging portion 16c disengages from the locking portion 4h, the state in which the lifting member 4 is held by the tenth lever 16 is released.
The lifting member 4 begins to move in the E direction due to the biasing force of the spring 8.

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 to the regulating recess 4C side. As a result, the CD drive mechanism 3 is moved upward within the relief hole 5C of the tray 5 due to the urging force of the chucking spring 18, that is,! move in the direction. In that 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 Movement in this direction is also gradual.

As the CD drive mechanism 3 moves in one direction, 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 engages with the chucking hole 2a of the CD 2. Slanted recess 2 of clamp member 27
7b, and the CD 2 is chucked by the attraction force between the magnet 27c and the attraction plate 23c. Note that the chucking state is shown in FIG. 7 with CD2 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.

When the CD drive mechanism 3 reaches the highest position, the washer 21 and the anti-vibration rubber 20 come into contact with the E-ring 22, the chucking spring I8 is expanded, and the anti-vibration rubber 20 is slightly deformed, and the clamp member The CD drive mechanism 3 that chunked the CD 2 between the chucking spring 18 and the chucking spring 18
and is integrally floated independently from the chassis 1 etc. by the vibration isolating rubber 20. This provides vibration resistance against external vibrations that may occur in the chassis 1 and the like. Here, the CD drive mechanism 3 for the chassis 1 etc.
, the relative vibration of the CD 2 and the clamp member 27 occurs within the range of the gap between the regulation bottle 3a and the regulation recess 4C and the gap between the regulation hole 3C and the regulation bottle IC. In addition, in the above-mentioned floating state, the turntable 23
While rotating the CD 2, 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 loading position, the elevating member 4 automatically moves in the E direction to cause the CD drive mechanism 3 and the clamp member 27 to chuck the CD 2, making the operation easy. It is.

Furthermore, as the tray 5 moves in the F direction, the 20th Tsutare lever 36 is enabled to rotate in the B direction by the spring 35 at the stage when the 10th Tsutare lever 6 begins to rotate in the B direction. The lock lever 360 lock portion 36d is the tray 50
The lock part 36d is connected to the spring 3 before reaching the opening groove part 5h.
5 is pressed against the side wall 5g of the tray 5, the tray 5 is reliably locked at the loading position by the 20th locking lever 36.

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 portion 11b of the unloading operating lever 11 is pressed in the direction of the arrow, the contact portion 4g of the elevating member 4, which is in contact with the pressing portion 11c of the unloading operating lever 11 in the carry-in state, is pressed against the pressing portion 11c. is pressed in the F direction by
The lifting 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, the spring 17
As the tenth lever 16 rotates in the direction A under the urging force of , 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 thereby, The elevating member 4 is locked at the end in the F direction.

Further, since the contact portion 36c of the 20th bend lever 36 is in contact with the spring hook 16e of the 10th bend lever 16,
As the zero lever 16 rotates in the A direction, the 20th lever 36 also rotates in the A direction. As a result, the locking portion 36d separates from the locking groove 5h of the tray 5, and the lock at the end of the total tray 5 in the F direction is released, so the tray 5 is moved with the CD 2 by the biasing force of the unloading spring 33. It moves in the E direction, and CD2 is carried out. In this case, the unloading spring 33 is attached to the pulley 2 on which the load of the spring 30 is applied.
8, the contraction of the unloading spring 33 is buffered by the boot U 28 and is performed gently, and therefore the tray 5 is also unloaded slowly.

As described above, the CD 2 is unloaded after the CD drive mechanism 3 is lowered to make it out of contact with the CD 2. Therefore, the CD 2 is not damaged during unloading, and the unloading operation lever 11 The CD2 can be easily ejected by simply performing the following operations.
