Description

  The present invention relates to a disk drive device typified by a CD player and a DVD recorder, and more particularly to a disk drive device that allows a disk in the apparatus to be properly removed when the disk is replaced.

  2. Description of the Related Art Conventionally, disk drive devices that record music information or the like on a disk such as a CD or DVD and reproduce the recorded information are generally well known. Such a disk drive device has a disk drive unit equipped with a turntable for rotating the disk and a pickup moving in the radial direction of the disk, and the turntable chucks the center of the disk between the clamp plate and the disk drive unit. The recording information on the disc can be read and the information can be written by a pickup that moves in the radial direction while rotating the disc.

  In particular, as such a disk drive device, a disk transport mechanism that carries in and out a disk between a slit-shaped opening (slot part) and a turntable constituting the disk drive unit without using a tray on which the disk is placed is provided. Is known.

  Such a disk drive device is called a slot-in type, and as such a disk drive device, in order to prevent the disk to be taken out from being vigorously carried out from inside the device, the disk at the time of carry-out is placed on both sides in the longitudinal direction of the slot portion. The thing which provided the brake member for pinching | interposing from is known (for example, patent document 1).

JP-A-8-167208 (paragraphs 0125 to 0128 and FIGS. 14 to 15)

  However, according to the configuration in which the pair of left and right brake members are pressed against the end surface of the disc as in Patent Document 1, the braking force acting on the disc varies due to the clamping force of the brake member, and the stop position of the disc changes each time. In the worst case, there is a possibility that the disk may fall out of the slot without being stopped.

  In particular, in Patent Document 1, since the disc is sandwiched by the brake member from both sides in the longitudinal direction of the slot portion, the pair of left and right brake members are in the vicinity of the slot portion in the housing, and the distance between the two is greater than the diameter of the disc. Must also be small.

  Therefore, the disk does not protrude greatly from the inside of the housing, and its center hole does not appear outside the housing. Therefore, when removing the disk from the slot, it is impossible to put a finger on the center hole, Therefore, there is a risk that the recorded information is deteriorated by touching the signal recording area of the disc with a finger.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to prevent the disk to be removed from dropping out of the slot portion while increasing the discharge amount so that the disk can be properly removed. It is to do so.

In order to achieve the above object, the present invention carries a disk transport that carries a disk inserted into a slot portion of a housing to a predetermined drive position in the housing and unloads the disk at the drive position out of the housing from the slot portion. A disk drive device comprising a mechanism, the disk transport mechanism having a disk pusher (extrusion arm 8) for applying a pressing force in the unloading direction to the disk,
When the disk is transported to the ejecting position where the disk is exposed to the outside with the first exposure amount by the operation of the disk transport mechanism, the movement of the pushing arm 8 in the disk unloading direction is restricted and the disk is moved to the ejecting position. The suspension of the ejecting arm 8 is released from the ejecting position by releasing the suspension of the ejecting arm 8 by the ejection interrupting means. It is characterized in that it is carried out to a position where it is exposed with a large second exposure amount.

  In the disk drive device as described above, the ejection interruption means is configured by engaging a cam member 25 fixed at a predetermined position and a cam follower 26 attached to the push-out arm 8. It is characterized by.

  According to the disk drive apparatus of the present invention, while the disk is temporarily stopped at the ejecting position exposed to the outside of the housing with the first exposure amount, the disk is unloaded by restarting the disk ejecting operation, and the disk is ejected. Since the disc is ejected from the ejecting position with the fingertip, it can be prevented from popping out and falling off, and the user's fingertip is waiting. When the disc is unloaded, the disc can be prevented from falling off even if the disc discharge amount is increased so that the central hole is exposed to the outside. The disc can be taken out without touching the signal recording area with a fingertip.

  Further, the ejection interruption means for temporarily stopping the disk at the ejecting position is based on the engagement between the cam member fixed at a predetermined position and the cam follower attached to the disk pusher for pressing the disk in the unloading direction. Since the cam mechanism is used, the disc can be reliably carried out without malfunction.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a configuration example of a disk drive device according to the present invention. In FIG. 1, reference numeral 1 denotes a chassis formed by pressing a metal plate, and a seat plate 3 is provided on the chassis 1 via a leaf spring 2.

  Then, a turntable 4 for rotating the disc and a pickup (not shown) are attached to the seat plate 3 to constitute a drive unit 5 (disc drive unit generally called a traverse mechanism) for recording / reproducing music information and the like. ing. Incidentally, the turntable 4 is directly connected to a drive shaft of a spindle motor (not shown) and is driven to rotate in one direction, and a pickup (not shown) moves in the radial direction of a disk that is driven to rotate on the turntable 4 while recording information is recorded. Read and write. The chassis 1 is fixed in a housing (not shown) with its upper portion covered by a top plate, which will be described later, and a slit-like opening (slot portion) for loading and unloading the disk is provided on the front surface of the housing. The disk inserted into the slot is automatically conveyed by the disk conveying mechanism inside and outside the housing.

  In the present invention, the disc loading end position by the disc transport mechanism is referred to as a drive position. At the drive position, the center of the disc and the turntable 4 coincides, and the turntable 4 and a clamp board (not shown) facing the turntable 4 are located. Thus, the center of the disk can be chucked. The end position of unloading the disk by the disk transport mechanism is called an eject position, and about half of the center hole of the disk is exposed to the outside from the slot portion at the eject position. In particular, according to the present invention, the disk is temporarily stopped in the middle of unloading before the disk reaches the ejection position by the ejection interruption means, and the disk position at this time is referred to as an ejection middle position. At the ejecting position, only a part of the end face of the disc is exposed to the outside (first exposure amount), and the ejection interruption means will be described later.

  Here, the disk transport mechanism includes a pair of left and right pull-in arms 6 and 7 for pulling the disk into the housing (position facing the drive unit 5), and an extrusion arm 8 (disk pusher) for pushing the disk inside the housing to the outside. ), A slide member 9 for operating the pull-in arms 6 and 7 and the push-out arm 8, a motor 10 capable of rotating in the forward and reverse directions for driving the slide member 9, and the like. Each end is provided with rollers 6a and 7a that contact the end face of the disk. Further, a contact member 8 a that contacts the end surface of the disk is also provided at one end of the push arm 8.

  The structure of the disk transport mechanism will be described in more detail with reference to FIG. 2 and FIG. 3. The retractable arms 6 and 7 are pivotally attached to the chassis 1 by pins 11 and 12, respectively, and one end of each of them. As mentioned above, the rollers 6a and 7a are provided, and the other ends of the two are connected via two links 13 and 14, respectively. The link 14 is rotatably attached to the chassis 1 by a pin 15 and is connected to the link 13 by a connecting pin 16, and the other ends of the links 13 and 14 are respectively connected to the retracting arms 6 and 7. The connecting pins 17 and 18 are connected. As a result, the retractable arms 6 and 7 are rotated in the opposite directions through the links 13 and 14 so as to open and close each other.

  On the other hand, the push-out arm 8 as a disk pusher is attached to a pin 11 that forms the rotation center of the pull-in arm 6 and shares the rotation center with the pull-in arm 6. Here, a torsion spring 19 is attached to the pin 11 as shown in FIG. 3, and the torsion spring 19 urges the retracting arm 6 and the pushing arm 8 in the closing direction. That is, the retractable arm 6 is urged clockwise (disc loading direction) in FIG. 3 around the pin 11, and the pushing arm 8 is counterclockwise (disc unloading direction) in FIG. 3 around the pin 11. It is energized.

  2 and 3, the slide member 9 is a rack-like component provided on the side where the retractable arm 6 and the pushing arm 8 are arranged, and is slidably attached to the chassis 1. Yes. In particular, the slide member 9 is movable in its length direction (disc transport direction), and this includes a cam groove 9a for guiding the retracting arm 6 to rotate and a rotating guide for the pushing arm 8. A protrusion 9b is provided. A cylindrical follower pin 6b protruding from the pull-in arm 6 is inserted into the cam groove 9a, and the protrusion 9b is slidably contacted with the side surface of the push arm 8.

  According to this example, when the slide member 9 slides in the direction of the arrow in FIG. 3 (disk loading direction L 1), the retractable arm 6 is centered on the pin 11 by the action of the cam groove 9 a and the torsion spring 19. 3, while the projection 9 b presses the pushing arm 8, the pushing arm 8 is turned clockwise about the pin 11 against the urging force of the torsion spring 19. It is made to do. When one of the retractable arms 6 is rotated in the clockwise direction of FIG. 3 by sliding of the slide member 9, the other retractable arm 7 is rotated in the counterclockwise direction of FIG. Therefore, the interval between the rollers 6a and 7a is gradually narrowed. However, when the slide member 9 reaches the end position in the L1 direction, the rotation of the pair of retracting arms 6 and 7 is changed in the reverse direction by the action of the cam groove 9a and the links 13 and 14, and thereby the rollers 6a and 7a. Is separated from the end face of the disc.

  Here, the chassis 1 is provided with a transmission mechanism 20 between the slide member 9 and the motor 10 as shown in FIG. 2, and the power of the motor 10 is transmitted to the slide member 9 via the transmission mechanism 20. It is. The transmission mechanism 20 is a gear train having a two-stage cam gear 21 including a pinion portion 21 a, and the pinion portion 21 a constituting the cam gear 21 is meshed with the rack portion 9 c of the slide member 9. ing.

  As apparent from FIGS. 2 and 3, the chassis 1 is provided with a slider 22 between a pair of left and right retracting arms 6 and 7. The slider 22 is a movable part that is slidable along the longitudinal direction of the slot, and is formed with a guide groove 22a that rises in an inclined manner. Further, a swing lever 24 having a pin 23 as a rotation fulcrum is stretched between the slider 22 and the slide member 9, and one end of the swing lever 24 is connected to the slider 22, and the other end of the swing lever 24 is slid. A U-shaped notch 24a that engages with a pin 9d protruding from the member 9 is formed.

  According to this example, when the slide member 9 advances in the L1 direction in FIG. 3, the pin 9d of the slide member engages with the notch 24a of the swing lever so that the swing lever 24 rotates counterclockwise in FIG. Thus, the drive unit is raised while the slider 22 is pulled toward the slide member 9.

  As is apparent from FIGS. 4 and 5, the drive unit 5 is provided with a guide pin 5a to be inserted into the guide groove 22a of the slider, so that the slider 22 moves toward the slide member 9 as described above. Then, the drive operation of the drive unit 5 is performed as shown in FIG. 5 by pushing up the guide pins 5a along the guide grooves 22a. When the slider 22 moves away from the slide member 9, the guide pin 5a is pushed down along the guide groove 22a, so that the drive unit 5 is lowered to an inclined posture while the leaf spring 2 is bent as shown in FIG. It will be. The ascending operation of the drive unit 5 is performed continuously with the disc carrying-in operation by the disc transport mechanism, and the disc is supported by the turntable 4 when the ascent of the drive unit 5 is completed (specifically, the turntable 4 faces the turntable 4). The disc is chucked so that the center of the disc can be rotated by the clamp plate). The lowering operation of the drive unit 5 is performed prior to the disk unloading operation by the disk transport mechanism. When the drive unit 5 starts to descend, the disk is replaced by the pull-in arms 6, 7 and the pushing arm 8 in place of the turntable 4. Held part.

  Next, a configuration example of the eject interrupting means constituting the main part of the present invention will be described with reference to FIGS. 6 to 8. The eject interrupting means includes a cam member 25 fixed at a predetermined position and a disk pusher. And a cam follower 26 attached to the push-out arm 8. Among these, the cam member 25 is a plate-like member in which a cam groove 27 is formed on the side facing the extrusion arm 8. In particular, as shown in FIG. 7, the cam groove 27 has an intermediate portion divided into two paths 27 a and 27 b via a partition wall 28, and the partition wall 28 is formed with a recess 29 cut out in a V shape. The

  On the other hand, the cam follower 26 is an arm-shaped part whose one end is pivotally attached to an intermediate portion of the push-out arm 8 by a pin 26a, and is engaged with a cam groove 27 of the cam member 25 on the free end side. A driven pin 26b is formed. In particular, as shown in FIGS. 6 and 8, the cam follower 26 is provided with a friction piece 26c that comes into contact with the portion of the push arm 8, and the friction piece 26c provides a predetermined rotational resistance force to the cam follower 26. The cam follower 26 can be kept stationary unless an external force exceeding the rotational resistance is applied.

  Then, according to the ejection interruption means as described above, the cam follower 26 attached to the push-out arm is moved by the rotation of the push-out arm 8, whereby the follower pin 26 b of the cam follower is moved into the cam groove 27. The inside moves along the shape, and the driven pin 26b is guided to the recess 29 in the cam groove 27 particularly when the disc is unloaded, and at this time, the rotational movement of the push-out arm 8 with respect to the unloading direction of the disc is restricted. The unloading operation is interrupted.

  In FIG. 9, reference numeral 30 denotes a top plate that covers the upper portion of the drive unit 5, and the cam member 25 is fixed to the top plate 30 at a position facing the extrusion arm 8. As is clear from FIG. 9, a clamp board 31 is attached to the top plate 30 at a position facing the turntable 4.

  Here, the operation of the ejection interruption means will be described with reference to FIG. 10. FIG. 10 (1) is the initial state (before the disk is inserted into the slot), and at this time, the pushing arm 8 is moved in the direction of arrow A (disk The side surface portion is pressed against the protrusion 9b of the slide member. The cam follower 26 is stationary with its follower pin 26 b at one end of the cam groove 27.

  In this state, when a disk is inserted into the housing from a slot portion (not shown), the end surface of the disk comes into contact with the contact member 8a of the push arm, and thereby the push arm 8 is pushed by the disk, and as shown in FIG. It is rotated in the direction of the arrow B (disk loading direction). At this time, the follower pin 26b of the cam follower has a turning radius R1 and advances through the first path 27a in the cam groove 27. Then, when the pushing arm 8 is rotated to a predetermined position by the user pushing the disk, this is detected by a sensor (not shown) and the disk transport mechanism is activated to carry the disk, whereby the projection 9b of the slide member is moved. The pushing arm 8 is further rotated in the direction of arrow B while moving in the direction of arrow L1 (disk loading direction) in FIG.

  Thus, when the loading of the disc is completed, the pushing arm 8 is stopped at the position shown in FIG. 10 (3) while the side surface thereof is pressed against the protrusion 9b of the slide member by the torsion spring 19. At this time, the driven pin 26b is positioned at the tip of the first path 27a of the cam groove, and the turning radius is changed to R2 (R2 <R1).

  On the other hand, when the disk is unloaded, the protrusion 9b of the slide member moves in the direction of the arrow L2 (disk unloading direction) in FIG. It is rotated in the A direction. At this time, the driven pin 9b moves in the direction opposite to that at the time of carrying in the path 27a. However, since the turning radius is changed to R2 as described above, the driven pin 26b is moved from the first path 27a to the second path 27a. Guided to the path 27b side. At this time, the driven pin 26b is fitted into the concave portion 29 of the partition wall that divides the paths 27a and 27b. For this reason, the pushing arm 8 is restrained by the ejection interruption means, and the rotational movement in the direction of arrow A (disc unloading direction) in FIG. 10 (4) is restricted. At this time, the disc receives a pressing force from the pushing arm 8. Without stopping, it is temporarily stopped at the ejecting position.

  Here, when the exposed end surface of the disk (the end surface exposed to the outside of the housing) is pushed from the outside by the user, the push arm 8 is rotated in the direction of arrow B in FIG. When the pin 26b is fitted into the recess 29, the turning radius is changed from R2 to R3 (R3 <R2), so that the pin 26b does not enter the path 27a as shown in FIGS. 10 (4) to 10 (5). In this way, the rotation radius advances from R3 to R4 and proceeds to the end of the path 27b.

  Thereafter, when the user stops pushing in the disc, the pushing arm 8 is rotated in the direction of arrow A (disc unloading direction) in FIG. 10 (6) by the urging force of the torsion spring 19. At this time, the driven pin 26b Since it moves in the path 27b without colliding with the partition wall 28 with the turning radius R4, the movement restriction of the pushing arm 8 by the ejection interruption means is released, and the pushing arm 8 is moved to the arrow A in FIG. 10 (6). The end surface of the disk is pressed in the unloading direction while rotating in the direction, and thus the disk is unloaded to an ejection position where the disk is exposed with an exposure amount (second exposure amount) larger than the ejection midway position.

  Note that when the disc is ejected to the eject position, the user's fingertip that has pushed the exposed end face to wait for the disc to wait for the disc to be ejected waits for the disc. Can be taken out.

  Next, a disc transport operation by the disc transport mechanism will be described. First, the disk loading operation will be described with reference to FIG. 11. FIG. 11 (1) shows an initial state (before the disk is loaded). At this time, one retractable arm 6 slides the driven pin 6b by the urging force of the torsion spring 19. The member is positioned in a state of being pressed against one surface of the cam groove 9a of the member. The other retractable arm 7 is positioned while being pressed against the wall surface of the chassis 1 through the links 13 and 14, and in this state, the distance between the left and right rollers 6a and 7a is smaller than the diameter of the disk D. . The push arm 8 is positioned in a state where it is pressed against the protrusion 9b of the slide member by the torsion spring 19.

  In this state, when the disk D is inserted into the slot portion from the outside, the end surface of the disk D comes into contact with the rollers 6a and 7a. When the disk D is further pushed in, the rollers 6a and 7a are pushed by the pushing force, so 6 and 7 are spread against the biasing force of the torsion spring 19.

  When the center portion of the disk passes between the rollers 6a and 7a, the end surface of the disk D comes into contact with the contact member 8a of the pushing arm as shown in FIG. Since the rollers 6a and 7a and the contact member 8a are pressed against the end face of the disk D by the action of the spring 19, the disk D is supported at three points. Further, at the stage where the disk D is supported at three points by the rollers 6a, 7a of the retracting arm and the contact member 8a of the pushing arm, the position of the retracting arm 6 is detected by a sensor (not shown), and the disk is detected based on the detection signal. The movement of the slide member 9 in the carry-in direction L1 is started.

  Then, the pushing arm 8 is pressed on the side surface by the projection 9b of the slide member 9 and rotated clockwise in FIG. 11 (2), while the retracting arms 6 and 7 are biased by the torsion spring 19 in the closing direction. Then, the disk D is pressed toward the pushing arm 8 side. For this reason, the disk D is moved in the loading direction L1 while being supported at three points by the rollers 6a and 7a of the pull-in arm and the contact member 8a of the push-out arm, and eventually the position where the center of the disk faces the turntable (drive) Position).

  FIG. 11 (3) shows a state where the disk has reached the drive position. In this state, the rotation of the retractable arms 6 and 7 is restricted by the shape of the cam groove 9a of the slide member 9, and the push arm 8 slides. The protrusion 9b of the member does not rotate clockwise in FIG. 11 (3), but only the counterclockwise rotation by the torsion spring 19 is prevented, so that the disk D is supported at three points. Although it is stopped at the drive position, the slide member 9 continues to be moved thereafter.

  When the movement of the slide member 9 continues even after the disk D reaches the drive position, the pin 9d of the slide member eventually engages with the notch 24a of the swing lever as shown in FIG. The moving lever 24 pulls the slider 22 toward the slide member 9 while being rotated counterclockwise in FIG.

  For this reason, the drive unit 5 is raised, and the disk D which is stopped at the drive position by the turntable 4 mounted on the drive unit 5 is supported at the center, and its chucking operation (the center of the disk by the turntable and the clamp plate) Part). 11, the slider 22 and the chassis 1 are linked by a toggle spring 32. When the slider 22 is located on the right side, a rightward biasing force is applied from the toggle spring 32, and the slider 22 is located on the left side. When this is done, a leftward biasing force is applied from the toggle spring 32, so that the lifting drive force of the drive unit 5 can be reduced while positioning the slider 22.

  In parallel with the disk chucking operation as described above, the retractable arm 6 is rotated in the reverse direction by the cam groove 9a of the slide member 9 pressing the driven pin 6b to the right in FIG. 11 (4). In addition, when the protrusion 9b of the slide member 9 presses the side surface of the extrusion arm 8 and the rotation of the extrusion arm 8 is resumed, the rollers 6a and 7a and the contact member 8a are moved as shown in FIG. The disk is separated from the outer peripheral end surface of the disk, so that the preparation for driving the disk D is completed.

  On the other hand, the disk is unloaded by an operation opposite to the above-described operation. However, at the time of unloading the disk, the disk is temporarily stopped at the ejecting position as described above by the ejection interruption means.

  Specifically, when the disk D is unloaded by the disk transport mechanism, the slide member 9 is moved in the direction of the arrow L2 (disk unloading direction) in FIG. , 7a and the pushing arm contact member 8a support the disk D. When the slide member 9 further moves in the L2 direction, the pusher arm 8 is rotated counterclockwise (disc unloading direction) in FIG. 12 (1) by the action of the torsion spring 19, and the disc D comes into contact with the pusher arm. The end surface is pressed by the member 8a, and it is carried out to the ejection halfway position.

  In the ejection halfway position shown in FIG. 12 (1), the push-out arm 8 is restricted from rotational movement in the disk unloading direction by the ejection interruption means as described above. For this reason, the disk has a part of its end face outside. In the exposed state (first exposure amount), it is temporarily stopped at the ejecting position.

  At this stage, when the exposed end surface e of the disk being temporarily stopped is pushed into the ejecting position into the housing (in the loading direction), the pushing arm 8 is pushed by the disk D as shown in FIG. By rotating clockwise, the follower pin 26 b of the cam follower is detached from the recess 29 in the cam groove 27.

  Thereafter, when the push-in of the disk D is stopped, the push-out arm 8 is not restricted by the ejection interruption means, but is rotated counterclockwise (disk) while pressing the end face of the disk in the unloading direction as shown in FIG. It rotates in the carry-out direction).

  Thus, as shown in FIG. 12 (4), the disk D is re-unloaded to a position where the exposure amount (second exposure amount) is larger than the ejecting position while being pressed by the push-out arm 8. After the center portion passes between the rollers 6a and 7a, the pushing arm 8 is stopped by the follower pin 26b of the cam follower and the projection 9b of the slide member, while the pressure contact force of the rollers 6a and 7a with respect to the disk D is reduced. As a result of acting in the direction in which the disk D is carried out, the disk D is pushed out by the retracting arms 6 and 7 more greatly than the position of FIG. 12 (4), and finally the center hole h is exposed outside the housing from the slot portion. It will be carried out to the eject position.

  Accordingly, it is possible to take out the disc without touching the center hole h of the disc and touching the signal recording area of the disc D. When the disk D is unloaded to the eject position, the user's fingertip that has pushed the exposed end surface e to resume unloading of the disk D waits for the disk D as described above. It will not drop out.

  Although the present invention has been described above, the disk pusher that applies the pressing force in the unloading direction to the disk is not limited to the pusher arm 8 that performs the rotational movement as described above, but is spring-biased in the unloading direction of the disk. A member that moves straight in the same direction in the state may be used.

  Further, it is sufficient that the disc is discharged from the ejecting position, and the discharge amount (exposure amount) is larger than the ejecting position, and the center hole of the disc does not necessarily have to be exposed to the outside at the ejecting position.

  The present invention can be applied to various disk drive devices such as a CD player, a DVD recorder, or a car navigation DVD player.
