Description

Description: TECHNICAL FIELD The present invention relates to a disc player for manually moving a moving member having a disc mounting portion from a carry-out position to a carry-in position.

[Conventional technology]

Conventionally, an optical reproducing device such as a compact disc player has been positioned as a high-end product, and a tray type of disc loading / unloading is usually electrically and automatically performed. That is, the moving member such as the tray is driven by the motor through the speed reduction mechanism.

However, in that case, unless the engagement timing between the rack mounted on the moving member and the drive gear is accurately controlled, the engagement rate between the rack and the gear is increased and the failure rate increases. There is a problem that an opening / closing means is required to accurately control the meshing timing. Further, it is necessary to match the locking timing of the locking means for locking the moving member at the loading position and the unlocking timing with the gear engagement timing with the gear and the locking means. However, it is complicated to consider the combination of opening and closing means.

In addition to the above-mentioned problems, compact disc players and the like have come into widespread use, and there has been a demand for the development of a manual type device capable of manually inserting a disc into the device.

As such a manual disc player, conventionally, there is one in which a first moving member for mounting and storing a disc is connected to a second moving member by a spring, and a pressing portion for manually pressing the second moving member is provided. Proposed (JP-A-62-250549)
(See Japanese Patent Publication).

[Problems to be Solved by the Invention]

However, in the above manual disc player,
Since it is necessary to move the second moving member from the open position to the closed position by a stroke longer than the moving stroke of the first moving member, there is a problem that the operation stroke becomes long.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, a disc player according to the invention of claim 1 of the present specification has a player main body and a disc mounting portion, and is provided between the unloading position and the loading position by the main body. A movable member movably supported by the first elastic urging member and urged toward the carry-out position by the first elastic urging member,
It is possible to drive the disc and read the information on the disc, and when the moving member is in the carry-out position, it is located at the lower position, which is the non-engagement position with the disc, while moving the moving member to the carry-in position. Accordingly, a disc drive mechanism supported by the player main body so as to be movable up and down so as to be moved by an urging force of the second elastic urging member to an upper position which is an engagement position with the disc. It is a thing.

A disk player according to the invention of claim 2 of the present specification, in addition to the structure of claim 1, has a structure for manually moving the disk drive mechanism from an upper position to a lower position. When the carry-out operation member and the disk drive mechanism are moved from the upper position to the lower position by the carry-out operation member, the movement of the moving member by the first elastic biasing member from the carry-in position to the carry-out position is started in synchronization with the movement. The interlocking part is provided.

Furthermore, a disc player according to the invention of claim 3 of the present specification is, in addition to the configuration of claim 1,
It is characterized in that a damper member is provided for cushioning the movement of the disk drive mechanism from the lower position to the upper position.

[Work]

In the disc player according to claim 1, the movement of the moving member from the carry-out position to the carry-in position is manually performed against the urging force of the first elastic urging member, while the move from the carry-in position to the carry-out position is performed. The movement is performed by the urging force of the first elastic urging member. The movement of the disc drive mechanism from the lower position to the upper position is performed by the urging force of the second elastic urging member. Thus, the movement of the moving member and the disk drive mechanism is performed manually and by the urging force of the elastic urging member, and the conventional electric drive mechanism becomes unnecessary. Moreover, since the moving stroke of the moving member is sufficient only by the distance between the carry-out position and the carry-in position, the operation stroke does not become long.

Next, in the disc player according to the second aspect of the present invention, the movement of the disc drive mechanism from the upper position to the lower position is manually performed by the unloading operation member, and the disc drive mechanism is moved to the lower position by the unloading operation member. When the disk is moved out, the movement of the moving member to the unloading position side based on the urging force of the first elastic urging member is started in a linked manner. You can easily do it just by doing. Also, the movement of the moving member to the carrying position side is started after the disc drive mechanism has moved to the lower position, which is the non-engaging position with the disc, so that the disc driving mechanism moves to the unloading position. The mechanism does not contact the disk and damage it.

Then, in the disc player according to the third aspect, the movement of the disc drive mechanism from the lower position to the upper position based on the urging force of the second elastic urging member is buffered by the damper member and is gently performed. The shock when the disk is delivered from the moving member to the disk drive mechanism is sufficiently mitigated, and damage to the disk is avoided.

Is substantially U-shaped by winding around the outer periphery of the pulley 28 and changing its direction, and the other end thereof is locked by a spring hooking pin 5b provided on the tray 5. The tray 5 is biased in the E direction by the carry-out spring 33. As described above, since the unloading spring 33 is U-shaped by passing through the pulley 28, the unloading spring 33 having a long free length can be used to reduce the spring constant. . Therefore, the operating force when the tray 5 is manually operated in the F direction against the biasing force of the unloading spring 33 can be made sufficiently small.

Further, since the carry-out spring 33 is wound around the pulley 28 which is loaded by the spring 30, the carry-out spring 33 is carried out.
The expansion and contraction of is dampened by the pulley 28 having a function as a damper. As a result, the movement of the tray 5 in the E direction based on the biasing force of the carry-out spring 33 also becomes gentle. A saw screw 34 engageable with the spring hooking pin 5b of the tray 5 is screwed into the screw hole 6d of the side plate 6 so as to project inward of the side plate 6, and the tray 5 is moved in the E direction by a predetermined stroke.

A spring 35 is inserted above the first lock lever 16 at the fulcrum pin 1e, and a second lock lever 36, which functions as an interlocking portion, is rotatably inserted above the spring 35 at the insertion hole 36a. The E-ring 37 prevents it from coming off. The spring 35 includes a spring hook 16e of the first lock lever 16 and a spring hook 3 of the second lock lever 36.
6b, so that the second lock lever 36 is biased in the direction of arrow B. The contact portion 36c of the second lock lever 36 contacts the spring hook 16e of the first lock lever 16 so that 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 is adapted to hold the tray 5 at the carry-in position by engaging with the lock 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, the anti-vibration rubber 20
Is held without being deformed and is simply placed on the CD drive mechanism 3, and only the chucking spring 18 is in a bent state. Not working.

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 on which the CD 2 is placed is manually pressed in the direction of arrow F against the urging force of the unloading spring 33, and the second It is moved from the carry-out position shown in FIGS. 4 to the carry-in position shown in FIGS. Then, the end surface 5i of the tray 5 comes into contact with the contact portion 16d of the first lock lever 16 slightly before the movement stroke of the tray 5 ends, and the first lock lever 16 moves in accordance with the movement of the tray 5 in the F direction. Rotates in the direction of arrow B against the biasing force of the spring 17. Along with this, the second lock lever 36 can also be rotated in the B direction by the urging force of the spring 35, and when the tray 5 is moved to the carry-in position, the second lock lever 36 is rotated in the B direction and the lock portion is moved. 36d is fitted in the locking groove 5h of the tray 5, and 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. Then, when the engaging portion 16c is disengaged from the lock portion 4h, the locked state at the end portion of the elevating member 4 in the F direction by the first lock lever 16 is released, so that the elevating member 4 is biased by the spring 8. Starts moving in the E direction.

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 in the escape hole 5c of the tray 5, that is, in the I direction 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.
The movement in the I direction is also performed gently.

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 expands, and the vibration isolating rubber 20 is slightly deformed while the CD is being driven. The mechanism 3, the CD 2 and the clamp member 27 are integrally floated independently of the chassis 1 and the like by the chucking spring 18 and the anti-vibration rubber 20. 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 floating state described above, the turntable 2
While rotating the CD2 by 3, the optical pickup 24
Thus, the signal on the CD 2 is read.

As described above, when the CD 2 is mounted on the tray 5 and the tray 5 is manually moved in the F direction and loaded, the CD
The drive mechanism 3, the CD 2 and the clamp member 27 are the chassis 1
It floats independently from the etc. and has vibration resistance. 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 manually moved to the carry-in position, the elevating member 4 is automatically moved in the E direction to chuck the CD 2 by the CD drive mechanism 3 and the clamp member 27. Is also easy.

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 lock groove portion 5h, immediately after the lock portion 36d reaches the lock groove portion 5h, the tray 5 is loaded by the second lock lever 36. Locked in position.

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 at the loading position.
Is pushed in the F direction by the pushing portion 11c as the unloading operation lever 11 rotates in the D direction, and the lifting member 4 moves in the F direction against the biasing force of the spring 8.

Then, the restriction pins 3a of the CD drive mechanism 3 move from the restriction recess 4c of the lifting member 4 to the release recess 4d via the inclined recess 4e. Along with this, the CD drive mechanism 3 moves downward, that is, in the direction of arrow J against the biasing force of the chucking spring 18. Along with the movement of the CD drive mechanism 3 in the J direction, the fall prevention plate 27d of the clamp member 27 is provided.
Comes into contact with the upper surface of the base frame 25, and the chucking state of the CD 2 due to the magnetic force between the turntable 23 and the clamp member 27 is released. After that, CD drive mechanism 3
When moving in the direction, the CD 2 is placed on the receiving portion 5e of the tray 5, the engagement between the CD 2 and the turntable 23 is released, and the CD 2 reaches the lowest position.

When the elevating member 4 moves to the end portion in the F direction as the CD drive mechanism 3 descends, the first lock lever 16 rotates in the A direction by the urging force of the spring 17, so that the elevating member 4 moves. The engaging portion 16c, which has been engaged with the contact portion 4i, engages with the lock portion 4h, whereby the elevating member 4 is locked at the end portion in the F direction.

Further, since the contact portion 36c of the second lock lever 36 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 as the lock lever 16 rotates in the A direction. As a result, the lock portion 36d is disengaged from the lock groove portion 5h of the tray 5, and the lock of the tray 5 at the carry-in position is released. As a result, the tray 5 moves in the E direction along with the CD 2 by the urging force of the unloading spring 33, and reaches the unloading position. Here, the contraction of the unloading spring 33 is buffered by the pulley 28 and is performed gently as described above. Therefore, the ejection of the tray 5 is also performed gently.

As described above, the CD 2 is carried out after the CD drive mechanism 3 is lowered so as not to come into contact with the CD 2. Therefore, the CD 2 is not damaged by the carry-out, and the carrying-out operation lever 11 is not used. The CD2 can be easily carried out only by the operation of.

〔The invention's effect〕

As described above, the disc player according to the invention of claim 1 of the present specification has the player main body and the disc mounting portion, and is movable by the main body between the carry-out position and the carry-in position. The moving member is supported and is urged toward the unloading position by the first elastic urging member, and the disc can be driven and the information on the disc can be read. When the moving member is at the unloading position, the disc is moved. Is located at a lower position which is a non-engagement position of the disk, and is second at an upper position which is an engagement position with the disk as the moving member moves to the carry-in position.
The disk drive mechanism is supported by the player body so as to be movable up and down so as to be moved by the urging force of the elastic urging member.

Accordingly, the movement of the moving member from the carry-out position to the carry-in position is manually performed against the biasing force of the first elastic biasing member, while the movement from the carry-in position to the carry-out position is performed by the first elastic biasing member. This is done by the urging force of. The movement of the disc drive mechanism from the lower position to the upper position is performed by the urging force of the second elastic urging member. As described above, since the moving member and the disk drive mechanism are moved manually and by the urging force of the elastic urging member, the conventional electric drive mechanism is unnecessary, and the structure is simplified and the cost is reduced. it can. Moreover, since the moving stroke of the moving member is sufficient only by the distance between the carry-out position and the carry-in position, the operation stroke does not become long.

Next, a disc player according to the invention of claim 2 of the present specification, in addition to the configuration of claim 1,
When the unloading operation member for manually moving the disk drive mechanism from the upper position to the lower position and the disk drive mechanism moved from the upper position to the lower position by the unloading operation member are linked with the first elastic member. The interlocking portion that starts the movement of the moving member from the carry-in position to the carry-out position by the biasing member is provided.

Thus, the movement of the disk drive mechanism from the upper position to the lower position is manually performed by the unloading operation necessary member, and when the disk drive mechanism is moved to the lower position by the unloading operation member, the interlocking portion moves the moving member. Since the movement toward the unloading position side based on the urging force of the first elastic urging member is started, unloading of the disk can be easily performed only by operating the unloading operation member. Further, the movement of the moving member to the unloading position side is started after the disc drive mechanism has moved to the lower position which is the non-engaging position with the disc, so that the disc driving mechanism is moved during the movement of the moving member to the unloading position. Does not contact the disc and cause damage to the disc.

Subsequently, the disc player according to the invention of claim 3 of the present specification buffers the movement of the disc drive mechanism from the lower position to the upper position in addition to the structure of the first claim. This is a configuration in which a damper member is provided.

As a result, the movement of the disc drive mechanism from the lower position to the upper position based on the urging force of the second elastic urging member is buffered by the damper member and is gently performed, so that the disc is delivered from the moving member to the disc drive mechanism. The impact at the time of moving is sufficiently mitigated, and the effect of preventing damage to the disk at the time of delivery is exerted.

Claims (3)

[Claims] 1. A player main body and a disc mounting portion,
The moving member is movably supported between the carry-out position and the carry-in position by the main body, and the moving member biased to the carry-out position side by the first elastic biasing member can drive the disc and read the information on the disc. And when the moving member is in the carry-out position, it is located in the lower position, which is the non-engaging position with the disc, while it is in the upper position, which is the engaging position with the disc, as the moving member moves to the carry-in position. And a disk drive mechanism that is supported by a player main body so as to be movable up and down so as to be moved by the urging force of the second elastic urging member. 2. An unloading operation member for manually moving the disk drive mechanism from an upper position to a lower position, and when the disk drive mechanism is moved from the upper position to the lower position by the unloading operation member, it is interlocked with it. 2. The disc player according to claim 1, further comprising an interlocking portion that starts the movement of the moving member from the carry-in position to the carry-out position by the first elastic biasing member. 3. The disc player according to claim 1, further comprising a damper member for buffering movement of the disc drive mechanism from a lower position to an upper position.
