[0001]
[Industrial applications]
The present invention relates to an optical disc player for reproducing an optical disc such as a CD (compact disc), and more particularly to a loading mechanism of a type that discriminates both a 12 cm optical disc and an 8 cm optical disc and automatically sucks the disc into a predetermined position on a turntable. Things.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an on-vehicle optical disk player, a loading mechanism of a type for automatically sucking an optical disk into a predetermined position by inserting one of a 12 cm CD and an 8 cm CD from an optical disk insertion opening provided on an outer surface of a case is provided. Optical disc players are known.
[0003]
Such an optical disk player moves the optical disk inserted into the insertion slot to a predetermined position on the turntable by the loading mechanism, and holds the optical disk on the turntable by a chucking plate. It has become.
[0004]
Then, by rotating the turntable, the recording surface of the rotating optical disk is irradiated with light such as laser light from the optical pickup. Then, the light receiving element of the optical pickup detects return light from the surface of the optical disc, and reads a signal recorded on the optical disc so that a reproduction signal (hereinafter, referred to as an RF signal) is generated. Has become.
[0005]
Here, the loading mechanism is configured, for example, as shown in FIG. That is, in FIG. 9, a loading mechanism 1 includes a guide plate 2 disposed above an optical disk path inside an optical disk insertion slot (not shown) provided on an outer surface of a case of an optical disk player, and the guide plate 2. And a roller 3 disposed below the optical disk path so as to face the optical disk 2.
[0006]
The guide plate 2 is fixedly arranged, and its lower surface has a flat central portion 2a laterally with respect to the moving direction of the optical disk in the optical disk path, and inclined portions 2b, 2 extending obliquely downward on both sides of the central portion. c Are formed in a so-called drum shape.
[0007]
The roller 3 is rotatably supported around a rotation axis extending laterally with respect to the moving direction of the optical disk in the optical disk path, and has a relatively small diameter central portion 3a and both sides of the central portion in the axial direction. Tapered portions 3b, 3 whose diameter gradually increases toward the outside c Are formed in a so-called drum shape.
[0008]
Further, the rotation axis of the roller 3 is driven by a drive mechanism (not shown), and when the rotation axis is urged upward, the outer peripheral surface of the roller 3 becomes the lower surface of the guide plate 2. To be pressed against.
[0009]
Thereby, the optical disk 4 inserted into the optical disk path from the optical disk insertion opening of the optical disk player enters between the guide plate 2 and the roller 3 and is sandwiched between the guide plate 2 and the roller 3. Here, the roller 3 is driven to rotate around a rotation axis by a driving mechanism (not shown). Therefore, the optical disk 4 sandwiched between the guide plate 2 and the roller 3 is conveyed to the inside of the optical disk player based on the rotation of the roller 3, and is moved to a predetermined position on a turntable (not shown). .
[0010]
At this time, since the guide plate 2 and the roller 3 are each formed in a drum shape, the optical disc 4 conveyed by the rotation of the roller 3 is perpendicular to the conveyance direction by the shape of the guide plate 2 and the roller 3. With respect to the direction, it will receive a force towards the inside, ie towards the center.
Therefore, even if the center of the optical disk 4 is shifted from the center of the guide plate 2 and the roller 3 at the time of insertion, the optical disk 4 is moved to the center based on the shapes of the guide plate 2 and the roller 3 when being conveyed by the roller 3. Positioning, that is, centering can be performed. Thereby, the center of the optical disc 4 is moved to the center on the turntable. Thereafter, the optical disk 4 is fixedly held at a predetermined position on the turntable by the chucking plate.
[0011]
Thus, by rotating the turntable, the surface of the rotating optical disc 4 is irradiated with light such as laser light from the optical pickup. Then, the light receiving element of the optical pickup detects the return light from the recording surface of the optical disk, and reads the signal recorded on the optical disk 4 to generate an RF signal.
[0012]
[Problems to be solved by the invention]
However, in the loading mechanism 1 of the optical disk player configured as described above, the centering of the inserted optical disk 4 is performed on the optical disk 4 by the shape of the guide plate 2 and the roller 3 in the direction perpendicular to the transport direction. Can be effected by means of a force towards the center, ie towards the center.
For this reason, the above forces are caused by lateral displacement of the guide plate 2 and the roller 3, unbalance of the load for urging the rotating shaft of the roller 3 upward, displacement of the mounting height of the guide plate 2 and the roller 3, The left-right balance is lost due to a drum-shaped dimensional error between the plate 2 and the roller 3. Furthermore, the position of the turntable itself has some back and forth play at the optical disk insertion standby position in order to secure a floating space in the reproducing state.
[0013]
Thus, in some cases, the center of the optical disc 4 conveyed onto the turntable by the loading mechanism 1 cannot completely coincide with the center on the turntable. In particular, in the case of a so-called 8 cm optical disc, since the right and left displacement at the time of insertion with respect to the insertion slot is apt to occur, the displacement with respect to a predetermined position on the turntable tends to increase, so that there is a high possibility that a chucking error occurs. There was a problem.
[0014]
For this reason, there is a method of preventing the displacement of the optical disc 4 by providing a position regulating pin in the optical disc passage. Small diameter In the case of an 8 cm optical disk, the optical disk 4 may not be brought into contact with the position regulating pin, but may go under it, and the centering may not be performed correctly.
[0015]
The present invention has been made in consideration of the above points, and Small diameter discs such as It is an object of the present invention to provide a loading mechanism for an optical disc player, which enables accurate centering to be performed even when a disc is inserted.
[0016]
[Means for Solving the Problems]
According to the present invention, there is provided a turntable on which a disk is mounted and driven to rotate, a chassis rotatably supported at one end on one side of the turntable and extending on the turntable, A chucking plate attached to the other end of the chassis so as to face the turntable, a slide plate slidably attached to the chassis in the disk insertion direction, and a slide plate attached to the slide plate. By providing a rotating shaft with a rotating plate and a regulating shaft having a tapered portion at the lower end portion that becomes thinner as going downward with respect to the rotating plate, the tip of the disk comes into contact with the tapered portion. In this case, by shifting the contact position upward, the displacement of the insertion position of the disc with respect to the turntable is corrected.
[0021]
In this specification, directions and directions such as "up", "down", "up", and "down" indicate directions on the drawing when the optical disk player is placed as shown in FIG. . Therefore, when the optical disk player is placed in another direction, these directions and directions change according to the direction and direction of the optical disk player.
[0022]
[Action]
The displacement of the insertion position of the disk transported by the transport mechanism can be corrected by using the tapered portion provided at the lower end of the regulating shaft.
[0027]
【Example】
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS.
In addition, since the Examples described below are preferred specific examples of the present invention, various technically preferable limitations are added, but the scope of the present invention particularly limits the present invention in the following description. The embodiments are not limited to these embodiments unless otherwise described.
[0028]
1 and 2 show an embodiment of a loading mechanism of an optical disk player according to the present invention.
In these figures, a loading mechanism 10 is provided with a turntable 12 provided on a mechanical deck 11 (see FIG. 2) of an optical disk player, and is supported on one side of the turntable 12 so as to be swingable about a horizontal axis 13a. Chassis 13, a chucking plate 14 provided at a free end of the chassis 13, and the other side of the turntable 12 facing up and down so as to pinch and transport the inserted optical disc. It includes a guide plate 15 and a roller 16 arranged.
[0029]
2, the turntable 12 has an optical disk placed thereon and is driven to rotate by a drive mechanism (not shown). The mechanical deck 11 further includes an optical pickup (not shown). As a result, light such as laser light from an optical pickup is applied to an optical disc mounted on the turntable and driven to rotate, and return light from the recording surface of the optical disc is used as a light receiving element of the optical pickup. Is detected by
[0030]
The chassis 13 is rotatably supported around a horizontal axis 13 a extending in a tangential direction of the turntable 12, so that its free end 13 b approaches and separates from the turntable 12 of the mechanical deck 11. As described above, it is swung by a chucking drive mechanism (not shown).
[0031]
The chunking plate 14 is Times Movement causes its free end to move downward Times When the optical disk is moved, it comes into contact with the upper surface of the turntable 12 so that the optical disk placed on the turntable 12 is fixed and held, and so-called chucking is performed.
[0032]
The guide plate 15 is fixedly arranged above the optical disk path inside an optical disk insertion slot (not shown) provided on the outer surface of the case of the optical disk player. The guide plate 15 preferably has a lower surface having a flat central portion and an inclined portion extending obliquely downward on both sides of the central portion in a direction perpendicular to the optical disk insertion direction A in the optical disk path. It is shaped like a drum.
[0033]
The roller 16 is rotatably supported around a rotation axis extending laterally in the optical disc insertion direction A below the optical disc path so as to face the guide plate 15 from below. Preferably, it is formed in a so-called drum shape having a central portion having a relatively small diameter in the axial direction and a tapered portion whose diameter gradually increases outward on both sides of the central portion.
[0034]
The roller 16 is driven by a drive mechanism (not shown) to rotate in the direction of arrow X when inserting the optical disk and in the direction of arrow Y when ejecting the optical disk. As a result, the outer peripheral surface is pressed against the lower surface of the guide plate 15.
[0035]
Further, the chassis 13 includes a slide plate 17 slidable with respect to the chassis 13 in the optical disc insertion direction A, and a pair of rotating plates 18 and 19 rotatably attached to a lower surface of the slide plate 17. (See FIG. 1).
[0036]
As shown in FIG. 1, the slide plate 17 rises upward from the rear end in the optical disk insertion direction A, and furthermore, the engagement pieces 17a projecting to both sides and project upward near the front end in the optical disk insertion direction A. The slide shaft 17b thus implanted is engaged in a slot 13b provided along the center axis of the chassis 13. As a result, the slide plate 17 is slidably supported on the chassis 13 in the optical disk insertion direction A, and the slide shaft 17b abuts on the end of the slot 13b, whereby the optical disk insertion direction is reduced. Sliding to A is regulated. Further, the slide plate 17 has a contact portion 17c formed so as to protrude downward from the front end in the optical disc insertion direction A.
[0037]
The rotary plates 18 and 19 are formed symmetrically with respect to the center line of the slide plate 17, and are rotatably supported near the front end of the slide plate 17 by rotary shafts 18a and 19a, respectively. . Further, the rotary plates 18 and 19 are provided with left-handedness and right-handedness as shown by arrows B and C in FIG. 1 by springs 18b and 19b stretched between the rotary plates 18 and 19, respectively. .
[0038]
The rotating plates 18 and 19 are provided with lock pins 20 and 21 protruding upward slightly toward the center behind the rotating shafts 18a and 19a, and implanted so as to protrude downward at portions that further project outward. Regulated shafts 22 and 23 are provided.
[0039]
The lock pins 20 and 21 are fitted into lock grooves 13c and 13d formed in the chassis 13, respectively. Here, the lock grooves 13c and 13d are formed so as to extend in the optical disc insertion direction A, respectively, and include engagement portions 13e and 13f extending from the rear end toward the center.
[0040]
Accordingly, when the slide plate 17 is located on the rear end side with respect to the chassis 13 as shown in FIGS. 1 and 2, the rotating plates 18, 19 are biased by the springs 18b, 19b, The lock pins 20, 21 are engaged with the engagement portions 13e, 13f of the lock grooves 13c, 13d. Therefore, the slide plate 17 is prevented from sliding in the optical disc insertion direction A.
[0041]
Further, as shown in FIGS. 2 and 3, the lower ends of the restriction shafts 22 and 23 are formed so that the lower ends thereof are tapered, and the 8 cm optical disk 30 is centered in the state shown in FIG. When the tip of the optical disc 30 comes into contact with the contact portion 17c of the slide plate 17, the outer periphery of the optical disc 30 makes light contact with the regulating shafts 22 and 23 or leaves a slight gap. It is arranged to approach.
[0042]
Further, a stopper 24 is provided on the mechanical deck 11 for restricting the leading end of the optical disc 30 from descending.
[0043]
The loading device 10 according to the present embodiment is configured as described above. When an 8 cm optical disc is inserted first, the loading is performed as follows.
That is, in FIG. 1, the 8 cm optical disc 30 inserted into the optical disc path from the optical disc insertion opening of the optical disc player enters between the guide plate 15 and the roller 16 and is sandwiched between the guide plate 15 and the roller 16. You.
Here, the roller 16 is driven to rotate around the rotation axis in a direction indicated by an arrow X by a drive mechanism (not shown). Therefore, the optical disk 30 sandwiched between the guide plate 15 and the roller 16 is conveyed in the direction of arrow A toward the inside of the optical disk player based on the rotation of the roller 16, and the tip of the optical disk 30 slides. It comes into contact with the contact portion 17c of the plate 17.
[0044]
At this time, since the guide plate 15 and the roller 16 are each formed in a drum shape, the optical disc 30 conveyed by the rotation of the roller 16 is perpendicular to the conveyance direction by the shape of the guide plate 15 and the roller 16. With respect to the direction, it will receive a force towards the inside, ie towards the center. Therefore, even if the center of the optical disc 30 is shifted from the center of the guide plate 15 and the roller 16 at the time of insertion, the centering is performed based on the shape of the guide plate 15 and the roller 16 during the conveyance by the roller 16. Could be done. Thereby, the center of the optical disk 30 is moved to the center on the turntable.
[0045]
At this time, the outer periphery of the optical disk 30 is lightly in contact with the regulating shafts 22 and 23 on both sides or approaches with a slight gap. Therefore, since the rotating plates 18 and 19 are held at the same positions, the slide plate 17 is configured such that the lock pins 20 and 21 of the rotating plates 18 and 19 are engaged with the engagement portions 13 e and the locking grooves 13 c and 13 d of the chassis 13. 13f. Thus, since the slide plate 17 is locked at the position shown in FIGS. 1 and 2, the optical disk 30 is transported in the optical disk insertion direction A at the position where it comes into contact with the contact portion 17 c of the slide plate 17. Stops.
[0046]
Subsequently, the chassis 13 is driven to rotate about the horizontal axis 13a by a drive mechanism (not shown), and the chucking plate 14 attached to its free end is lowered. At this time, since the optical disk 30 is held between the guide plate 15 and the rollers 16, the center of the optical disk 30 is pressed by the chucking plate 14, so that the holding point between the guide plate 15 and the rollers 16 becomes a fulcrum. And swings in the direction of arrow P in FIG.
Since the optical disk 30 is pushed in the optical disk insertion direction A by the roller 16, the tip of the optical disk 30 descends while sliding while being in contact with the contact portion 17c of the slide plate 17. . Thus, as shown in FIGS. 4 to 6, the optical disc 30 stops swinging in the direction of the arrow P with the tip thereof being placed on the stopper 24.
[0047]
Further, the chassis 13 is driven to rotate about the horizontal axis 13a, and the chucking plate 14 descends, and at the same time, the rollers 16 start descending. Thus, the optical disk 30 swings in the direction of arrow Q in FIG. 5 with the mounting point on the stopper 24 as a fulcrum. After the vicinity of the center of the optical disk 30 comes into contact with the turntable 12, the optical disk 30 swings in the direction of arrow Q in FIG. At this time, the tip of the optical disk 30 is moved by the rotation of the roller 16 so that the contact portion 17 of the slide plate 17 c To Contact The contact portion 17 sliding on c While rising.
[0048]
Thus, the optical disk 30 is fixedly held on the turntable 12 by placing the chucking plate 14 on the turntable 12 with the optical disk 30 interposed therebetween.
[0049]
Here, when the 8 cm optical disc 30 is inserted, for example, when the center of the optical disc 30 is shifted to the left as shown by a chain line in FIG. When contacted, the outer periphery pushes the regulating shaft 22 outward.
As a result, the rotating plate 18 is turned clockwise against the tension of the spring 18b, so that the lock pin 20 is disengaged from the engaging portion 13e of the lock groove 13c of the chassis 13. On the other hand, since the optical disc 30 does not contact the regulating shaft 23, the rotating plate 19 does not rotate, and therefore, the lock pin 21 remains engaged with the engaging portion 13f of the lock groove 13c of the chassis 13. Thus, since the slide plate 17 is held at the position shown in FIG. 4, the 8 cm optical disc 30 can be positioned.
[0050]
Then, from this state, the vicinity of the center of the optical disk 30 is depressed by the lowering of the chucking plate 14, and the optical disk 30 swings downward with the holding point between the guide plate 15 and the roller 16 as a fulcrum, and the leading end thereof is a stopper. 24. At this time, since the outer circumference of the optical disk 30 slides to the tapered portion of the regulating shaft 22, the rotating plate 18 turns leftward due to the tension of the spring 18b, and the regulating shaft 22 returns to the original position. At the same time, the lock pin 20 is engaged with the engagement portion 13e.
[0051]
Thereafter, the chassis 13 is driven to rotate about the horizontal axis 13a, and the chucking plate 14 descends, and at the same time, the rollers 16 start descending. As a result, the optical disc 30 swings in the direction of arrow Q in FIG. 5 with the mounting point on the stopper 24 as a fulcrum. With the mounting point 12a as a fulcrum, it swings in the direction of arrow Q in FIG.
[0052]
At this time, the tip of the optical disk 30 is moved by the rotation of the roller 16 so that the contact portion 17 of the slide plate 17 c To Contact The contact portion 17 sliding on c While rising, the outer periphery of the optical disk 30 slides along the tapered portion of the regulating shaft 22 that has returned to the original position. Contact While rising. Thus, the optical disk 30 is pushed toward the center along the tapered portion of the regulating shaft 22, and the center of the optical disk 30 is accurately centered with respect to the centers of the chassis 13 and the turntable 12. Will be.
[0053]
On the other hand, when the center of the optical disc 30 is shifted to the right at the time of insertion of the 8 cm optical disc 30, the outer circumference of the optical disc 30 is changed when the tip of the optical disc 30 contacts the contact portion 17 c of the slide plate 17. Therefore, the regulating shaft 23 is pushed outward. Therefore, in contrast to the above-described leftward center deviation, when the leading end of the optical disk 30 is raised, the outer periphery of the optical disk 30 slides along the tapered portion of the regulating shaft 23. Contact By ascending, the optical disk 30 is pushed toward the center along the tapered portion of the regulating shaft 23, and is accurately centered.
[0054]
On the other hand, when inserting a 12 cm optical disk, the insertion is performed as follows.
That is, in FIG. 7, the 12 cm optical disk 31 inserted into the optical disk path from the optical disk insertion opening of the optical disk player enters between the guide plate 15 and the roller 16 and is sandwiched between the guide plate 15 and the roller 16. You. Thereby, the optical disk 31 sandwiched between the guide plate 15 and the roller 16 is conveyed in the direction of arrow A toward the inside of the optical disk player based on the rotation of the roller 16, and the tip of the optical disk 31 It comes into contact with the contact portion 17c of the slide plate 17.
[0055]
At this time, since the guide plate 15 and the roller 16 are each formed in a drum shape, the optical disc 31 conveyed by the rotation of the roller 16 is perpendicular to the conveyance direction by the shape of the guide plate 15 and the roller 16. With respect to the direction, it will receive a force towards the inside, ie towards the center. Therefore, even if the center of the optical disc 31 is shifted from the center of the guide plate 15 and the roller 16 at the time of insertion, the centering is performed based on the shape of the guide plate 15 and the roller 16 during the conveyance by the roller 16. Could be done. Thereby, the center of the optical disk 30 is moved to the center on the turntable.
[0056]
Further, at this time, the outer periphery of the optical disc 30 pushes the regulating shafts 22 and 23 on both sides outward. As a result, the rotating plate 18 is turned clockwise against the tension of the spring 18b, and the rotating plate 19 is turned counterclockwise against the tension of the spring 19b. The lock grooves 13c and 13d are disengaged from the engagement portions 13e and 13f. Thus, the slide plate 17 is brought into contact with the contact portion 17 by the optical disc 31 conveyed in the direction of arrow A by the rotation of the roller 16. c Is pushed in the direction of arrow A, and is slid toward the optical disc insertion direction A with respect to the chassis 13.
[0057]
As shown in FIG. 8, when the slide shaft 17b abuts on the front end of the slot 13b, the slide plate 17 stops sliding in the optical disk insertion direction A. At this time, the lock pins 20, 21 of the rotating plates 18, 19 abut against the side walls of the lock grooves 13c, 13d. Thus, the regulating shafts 22 and 23 are separated from the outer periphery of the optical disc 31. Thereafter, the chassis 13 rotates around the horizontal axis 13a, and the chucking plate 14 descends, so that the optical disc 31 is chucked on the turntable 12.
[0058]
As described above, in the above-described embodiment, when the optical disk is inserted, the optical disk has its leading end in contact with the slide plate. 17c And the outer circumference of the optical disk contacts the shaft. Thereafter, the optical disk is pivoted about the portion held by the guide plate and the roller by the lowering of the chucking plate, and the tip of the optical disk swings downward. Rocks.
[0059]
At this time, the tip of the optical disk rises, but since the vicinity of the tip of the shaft has a taper, the outer periphery of the optical disk is pushed inward toward the center line in the insertion direction based on the shape. Therefore, even when the optical disc is deviated from the center, the centering can be accurately performed based on the tapered shape of the tip of the shaft.
[0060]
Therefore, the centering of the optical disk, particularly, the 8 cm optical disk can be performed with high accuracy without increasing the component accuracy and the assembly accuracy. Thus, the assembly can be easily performed with a simple configuration, and the cost can be reduced.
[0061]
The slide plate is provided with locking means, which locks the slide plate at a position for positioning the 8 cm optical disc in the insertion direction, and when both shafts are pushed by the outer circumference of the optical disc. When the locking means releases the locking of the slide plate, the slide plate is moved to the corresponding positioning position for both the 8 cm optical disk and the 12 cm optical disk. Can be automatically determined.
[0062]
Also, the locking means is rotatably supported on the chassis symmetrically and rotatably with respect to the chassis, and an engagement planted on the rotation plate so as to engage with a slot provided in the chassis. In the case where a pin is provided and the shafts are respectively implanted in the rotating plate, when the optical disk is inserted, the outer periphery of the optical disk comes into contact with the shaft, whereby the locking of the slide plate to the chassis is released. Therefore, unlocking of the locking means can be performed by a simple mechanism.
[0063]
In addition, if a stopper is provided to restrict the tip of the optical disk from lowering when the chucking plate is lowered, the outer circumference of the optical disk that has pushed the shaft may be disengaged from the shaft when the optical disk is inserted. There is no. Therefore, when the tip of the optical disk subsequently rises, the center of the optical disk can be accurately centered by being pushed inward along the tapered portion of the shaft.
[0064]
In the above-described embodiment, the lower ends of the regulating shafts 22 and 23 are tapered, that is, formed in a conical shape. However, the present invention is not limited to this. The optical disk 30 may be shaped so that the outer periphery of the optical disk 30 is pushed toward the center by sliding along the lower ends of the regulating shafts 22 and 23. A thinner shape is appropriately adopted.
[0065]
【The invention's effect】
As described above, according to the present invention, there is provided a loading mechanism for a disc player, which can perform accurate centering using a tapered portion of a regulating shaft when a disc is inserted. .
