Description

  The present invention relates to a disk scooping device provided in a disk device.

There is a disk device capable of storing and reproducing a plurality of disks such as CDs and DVDs. Such a disk device has a disk replacement function for replacing a storage disk. When ejecting a disk, the target disk is placed on a disk seat and placed at a predetermined disk replacement reference position. After that, the disk is held by the holding arm (gripping member) in the front-rear (diameter) direction in advance, and then the disk transporting means including the opposing member that is paired with the roller is moved from the home position. The end of this disk is held between the opposite member and the opposite member.
On the other hand, the disk seat is automatically lowered when the time required for the holding arm to hold the disk is passed. Due to the lowering of the disk seat, the disk is held by the disk transfer means and the holding arm and remains in the space. As the roller rotates, the disc is sent out in the ejection direction. Normally, the disc is automatically ejected from the disc device by the above procedure.

  In such a disc ejection process, if the target disc is deformed or if the disc device receives vibration from the outside while the gripping member is going to grip, the holding arm may fail to grip the disc. . Here, the holding arm is designed to be displaced up to the stroke end inside the outer diameter of the disk to ensure the gripping margin of the disk when idling. When the holding arm is swung, the disc that has been lost by the holding arm is caught on one of the pair of holding arms, and the other side is supported on the disc receiving seat. The disk seat starts to descend after the holding arm is gripped. A plate is located below the predetermined replacement position. The disk seat passes through an opening formed in the plate and further descends to a standby position below to stand by.

  When the disc seat is lowered to the standby position below the plate, one end of the disc supported on the disc seat is hooked on the plate, the disc is tilted on the holding arm and the plate, It will fall and fall off. Under this state, the base roller moves depending on the inclination of the disk even if the disk transport means tries to move from the home position in order to pick up the disk at a predetermined timing in accordance with the disk ejection program. Since the falling disk blocks the path for this purpose, the base roller cannot move, the posture of the dropped and dropped disk is not corrected, and the disk cannot be ejected.

On the other hand, in an optical disk drive device, there is a technique that enables an optical disk to be centered at a chucking position without dropping from the tray when loading an optical disk in a standing posture (see, for example, Patent Document 1). In the technique of this patent document, a protrusion for centering an optical disk at a chucking position is provided on a frame that movably supports a tray. The protrusion has a slope surface for centering formed in an upward gradient with respect to the moving direction of the tray in accordance with the loading operation, and a tapered surface formed continuously from the end of the slope surface and having a shape in which the device inner side direction is lowered. . In accordance with the loading position operation, the optical disc is centered by the slope surface, and the posture of the optical disc is corrected by the tapered surface to prevent the optical disc from falling off the tray.
As described above, the technique of this patent document centers the disk by the protrusion, and does not correct the dropped disk.

Embodiment 1
[1] Configuration of Disc Scooping Device The disc scooping device of the present invention is provided as a part of the disc device. In FIG. 1, an opening 2 a for inserting / removing a disk is formed in a front side plate 2 of a housing-like frame 1. A support plate 4 is fixed on the inner side of the rear plate 3 facing the front plate 2. The support plate 4 supports a rear arm 5 as a gripping member for gripping the disk by links 6 and 7 that translate in the front-rear direction.

  A shaft 6a planted on the rear end side of the link 6 is slidably engaged with a guide groove 4a formed in the support plate 4 in the left-right direction. A shaft 7 a planted on the rear end side of the link 7 is pivotally supported by the support plate 4. The link 6 and the link 7 are pivotally connected by a pin 8 at the intersection.

  A shaft 6 b planted on the front end side of the link 6 is pivotally attached to the right end side of the rear arm 5. A shaft 7b planted on the rear end side of the link 7 is slidably engaged with a guide groove 5a formed in the left-right direction on the left end side of the rear arm 5. With this configuration, the rear arm 5 is translated in the front-rear direction. A shaft 11a is fixed to the frame 1 in the vertical direction in the vicinity of a corner portion where the left side plate 9 and the front side plate 2 intersect. A support plate 11 is supported on the shaft 11a so as to operate in the axial direction and to be rotatable about the shaft. The support plate 12 pivotally supports a shaft 11a implanted at the base end portion of the front arm 11 as a gripping member for gripping the disk. The front arm 11 and the rear arm 5 constitute a pair of holding arms that hold and hold the disk.

  The rear arm 5 can be translated from the home position on the rear side of the position shown in FIG. 1 to the front side as shown in FIG. The stroke of the rear arm 5 is a range from a home position sufficiently separated from the outer diameter portion of the disk centered on the disk receiving seat 14 to a position where the inner arm bites into the outer diameter portion of the disk. It abuts on the outer diameter of the disk located at the position by elastic force.

  The shaft 7a is biased by a torsion coil spring (not shown) so as to move the rear arm 5 forward. The shaft 7a is also connected to power means for returning the arm 5 to the home position after being displaced by the elastic force of the torsion coil spring. When the holding of the shaft 7a by the power means is released by the clutch in the home position, the rear arm 5 moves forward and can be returned to the home position by driving the power means.

  As shown in FIG. 1, the front arm 11 can be rotationally displaced in the counterclockwise direction with the home position where the free end side is close to the front plate 2 as a base position and the shaft 11 a as a fulcrum. The forearm 11 is displaced to a height position where the disk can be grasped. The displaced front arm 11 is rotated from the home position to the disk gripping position and from the gripping position to the home position by the rotational power means.

  The front arm 11 is sufficiently separated from the outer diameter portion of the disk centered on the disk receiving seat 14 at the home position shown in FIG. The front arm 11 can be rotated from the home position and positioned on the disk receiving seat 14 side, but the swing stroke is a range from the home position to a position that bites into the outside diameter portion of the disk, It abuts on the outer diameter of the disk located in the middle of this stroke with an elastic force.

  A plate 12 is located below the support plate 4. The plate 12 between the front arm 11 and the rear arm 5 is formed with a circular opening 12a large enough to allow the disk receiving seat 14 to pass therethrough. On the same axis as the opening 12a, a center shaft 13 having a size capable of entering the center hole of the disk is located. The center shaft 13 is combined with a disk seat 14 that is orthogonal to the axis of the center shaft 13, and the upper end of the center shaft 13 projects upward from the disk seat 14.

  The center shaft 13 and the disk receiving seat 14 are configured as a part of the core bar mechanism 15. The mandrel mechanism 15 causes the center shaft 13 and the disk seat 14 to integrally move up and down between the disk replacement reference position and the standby position below the disk replacement reference position without changing the position of the shaft center. As shown in FIG. 1, the standby position is a position below the plate 12, and the disk replacement reference position is a position above the plate 12.

  Under the condition that the disk seat 14 is positioned at the disk replacement reference position, a normal disk without deformation is placed on the disk seat 14 with its center hole fitted to the center shaft 13. When the front arm 11 and the rear arm 5 are started from their home positions, the front arm 11 and the rear arm 5 hold the disk with substantially the same holding force at substantially the same timing from the substantially radial direction of the disk. Moreover, it can return to each home position by the power means which drives each of these front arms and rear arms.

  The front arm 11 is positioned above the disk path in the home position so that the path of the disk inserted / removed through the opening 2a is not obstructed by the home position. The base end of the forearm 11 attached to the shaft 11a descends along the shaft 11a and returns to the original height while returning to the home position. .

  In FIG. 1, a disk transport means 16 is located below the front arm 11 at the home position. When the disc transport means 16 carries the disc into the disc receiving seat 14 with this position as the home position, and when the disc is ejected from the disc receiving seat 14, the disc transport means 16 translates from the home position to the rear side to carry in the loading, Displaces to the position where the disc is suitable for ejection. As shown in FIG. 2, the disk conveying means 16 includes a base member 17, two inclined members 19 supported at an interval in the left-right direction of the base member 17, and these inclined members 19. A plate-shaped counter member 20 having a U-shape covering the upper surface with a gap from above, a base roller 18 and the like. The opposing member 20 has side plate portions at both left and right ends fixed to the base member 17. The base roller 18 can move up and down along the long holes 10 formed in the left and right side plate portions, and can be rotated forward and backward by a power system (not shown). In FIG. 1, the description of the facing member 20 is omitted to avoid complication of the drawing.

  As shown in FIG. 3, a portion where the left and right side plates of the facing member 20 are connected in a bridging manner is located above the two inclined members 19 and the base roller 18 positioned in the left-right direction.

  As the disk conveying means 16 is displaced from the home position to the disk gripping position, the base roller 18 located below the upper surface of the inclined member 19 at the home position is displaced upward along the long hole 10 to face the opposing member. The disc can be held with the disc 20. The base roller 18 returns below the upper surface of the inclined member 19 as the disk transport means 16 returns to the home position.

  FIG. 4 is a diagram showing the displacement of the base roller 18 accompanying the displacement of the disk conveying means 16. As the disk transport means 16 located at the home position H moves backward from the home position H toward the disk gripping position P at the time of loading / unloading the disk, the base roller 18 also moves along a locus indicated by a solid line. Starting from the position before reaching the disk gripping position, it moves up along the long hole 10 to reach the position P where the disk can be gripped with the opposing member 20. At this position, the disk is carried in and out, and when this is completed, the disk returns to the home position H along a locus indicated by a broken line.

[2] Disc Loading Operation The step of loading the disc into the disc receiving seat 14 will be described.
Step 1:
In FIG. 5, the core rod mechanism 15 is located at a standby position below the plate 12. The rear arm 5 is located at a stroke end inside the outer shape of the disk. The disk transport means 16 is at the home position (position indicated by a two-dot chain line in FIG. 5). The base roller 18 is at the home position H below the upper surface of the inclined member 19. The front arm 11 is located above the facing member 20.

  In this state, when the disc D1 is inserted from the opening 2a in the direction of the solid line arrow, for example, a signal from a sensor that detects the entry of the disc D1 causes the transport means 16 to move toward the gripping position. In the middle of this movement, the base roller 18 moves upward and the leading end of the disk D1 is sandwiched between the base roller 18 and the opposing member 20, and the rotation of the base roller 18 causes the center shaft 13 to move. The shaft is sent to a position where the center of the disc matches the center of the center hole of the disc. Along with this feeding, the rear arm 5 moves backward while contacting the outer diameter portion of the disk D1.

Step 2:
In FIG. 6, the feed of the base roller 18 is stopped at the timing when the center hole of the disk D1 is positioned on the center axis of the center shaft 13, and the front arm 11 is displaced from the home position by using this as a trigger, and the front end side of the disk D1. Hold down. As a result, the disk D1 is held by the rear arm 5 and the front arm 11, and is held by the base roller 18 and the opposing member 20. Further, the core rod mechanism 15 starts to move upward by the trigger.

Step 3:
In FIG. 7, when the disk replacement reference position is reached, the upward movement is stopped, and the center shaft 13 is fitted into the center hole 21 of the disk D1.

Step 4:
In FIG. 8, the disk transport means 16 returns to the home position with the core rod mechanism 15 reaching the disk replacement reference position as a trigger. The disk D1 can be carried onto the disk receiving seat 14 by the above process.

  Thus, under the state where the disk D1 is loaded onto the disk receiving seat 14, the disks D2, D3 and D4 are already mounted on the center shaft 13 as shown in FIG. In this example, the storage example is three, but if the number of the disk receiving seats 14 is increased, a larger number of sheets can be stored.

  As shown in FIGS. 5 and 6, when loading a disk, an empty disk receiving seat 14 is previously positioned at the top of the center shaft 13. Further, when the disk is reproduced or ejected, the disk receiving seat 14 is moved so that the disc receiving seat 14 supporting the target disc is positioned at the uppermost position of the center shaft 13. For this reason, another core rod mechanism 150 is arranged concentrically with the center shaft 13 as shown in FIG. The core rod mechanism 150 includes a center shaft 130 having the same configuration as the center shaft 13.

  In FIG. 9, for example, if the target disk is the disk D 3, the core bar mechanism 150 is lowered from above with respect to the core bar mechanism 15 in the disk replacement position, and the center shaft 130 is moved to the end of the center shaft 13. After the ends are matched, the disks D1 and D2 are moved to the center shaft 130 together with the respective disk receiving seats 14, and at the same time the disk D3 is positioned at the uppermost position of the center shaft 13, the core rod mechanism 150 is moved. Raise.

  There are various means for moving the disk seat 14 on the center shafts 13 and 130, but as an example, the principle of screws and nuts is applied. Although it is actually complicated, when it is simplified, it becomes as shown in FIG. The center shafts 13 and 130 are formed with a plurality of cam grooves spirally on the outer periphery, and projecting portions protruding from the inner diameter portion of the disk receiving seat 14 are engaged therewith. Further, a recess 14a is formed in the inner diameter portion of the disk receiving seat 14, and a locking rod 22 that is paired with the center shaft 13 is engaged with the recess 24a. The position of the recess 14a is set inside the center hole 21 of the disk.

  The center shaft 130 is also provided with a detent rod 220 that is paired therewith. When the end portion of the center shaft 130 matches the end portion of the center shaft 13, the end portions of the detent bars 22 and 220 also match. When the center shafts 13 and 130 rotate integrally in synchronism with each other in a state in which the end portions match each other, the detent rod 22 is supported by an appropriate immovable member and does not move.

  In such a configuration, when the center shaft 13 and the center shaft 130 are rotated integrally in synchronism, the disk receiving seat 14 corresponding to a nut can be moved in the longitudinal direction of the shaft although it is prevented from rotating, the center shaft 13 , 130 are guided between the cam grooves and moved between the center shafts 13 and 130. For example, the position of the disk seat 14 can be set at a desired position by controlling the amount of rotation of the center shafts 13 and 130 in relation to the pitch of the cam grooves, leads, and the like.

  When reproducing a disc, the selected disc is positioned at the top of the center shaft 13. Then, the core bar mechanism 15 is displaced to the disk replacement reference position, and the disk is gripped by the front arm 11 and the rear arm 5. This state is the same as the state shown in FIG. After the core rod mechanism 15 is lowered toward the standby position, the disk is centered and supported by the reproducing apparatus, and then the front arm 11 and the rear arm 5 are retracted to the home position to perform reproduction.

[3] Disc Ejecting Operation The disc ejecting operation follows substantially the reverse process of the aforementioned disc loading operation.
Step 1:
As shown in FIG. 8, the disk D1 to be ejected is positioned at the top of the center shaft 13 together with the disk receiving seat 14. Thereafter, the core rod mechanism 15 is displaced to the disk replacement reference position. The front arm 11, the rear arm 5 and the disk transport means 16 are at their home positions.

Step 2:
As shown in FIG. 7, the disk D <b> 1 on the disk receiving seat 14 is held between the front arm 11 and the rear arm 5.

Step 3:
The disk transport means 16 is moved from the home position to the disk holding position. As a result, the disk D1 is sandwiched between the base roller 18 and the opposing member 20. Next, the core rod mechanism 15 is lowered toward the standby position, and the front arm 11 and the rear arm 5 are retracted to the home position.

Step 4:
In FIG. 5, the base roller 18 is rotated, and the disk D1 is sent out from the opening 2a as indicated by a broken line arrow. Since the forearm 11 at the home position is retracted to the home position outside the course of the disk D1, there is no obstacle to the ejection of the disk D1. After the disk D1 is sent out, the disk transport means 16 returns to the home position.

[4] Comparative Example In step 2 of the ejection step, as shown in FIG. 7, the disk D1 on the disk receiving seat 14 is held with the front arm 11 and the rear arm 5 sandwiching the disk D1. If the vehicle mounted with the disk device vibrates at the timing when the arm 11 and the rear arm 5 are closed, or if the disk D1 is deformed, the edge of the disk is displaced from the normal position. The disc D1 may ride on either the front arm 11 or the rear arm 5 located at the stroke end due to the idling of the rear arm 5.

  In FIG. 11, the disk D1 indicated by the solid line is tilted forward on the arm 5 after the rear side is displaced to the stroke end, and the disk D1 indicated by the two-dot chain line is tilted rearward on the front arm 11. Yes. The other side of the disk is once supported on the disk receiving seat 14 but remains on the plate 12 as the disk receiving seat 14 is lowered. Therefore, when the rear side of the disk D1 is hung on the rear arm 5, the front side of the disk D1 is hung on the stepped portion between the plate 12 and the base member 17, and one side of the disk D1 rides on the front arm 11. Is in a state of hanging on the plate 12.

  As described above, the disk D1 is inclined between the holding arm including the front arm 11 and the rear arm 5 and the plate 12, and is dropped and dropped from the disk receiving seat 14. Under this state, even if it is attempted to move the disk transport means 16 to the disk holding position at a predetermined timing in accordance with the disk ejection program, the disk D1 becomes an obstacle and the disk transport means 16 moves. In addition, the posture of the dropped / dropped disk is not corrected, and the disk cannot be ejected.

[5] Disc Ejection Operation When Dropping When the holding arm cannot swing and grip the disc as in the above comparative example, the holding arm moves in the clamping direction up to a maximum stroke larger than the normal gripping operation. The situation can be detected by installing a sensor. In such a case, one end of the disk is placed on the plate 12 and the other end is inclined by being supported by the holding arm.

  Therefore, when the swinging movement of the holding arm is detected based on the information from the sensor, the control means changes the normal disk ejection sequence and switches to the dropped disk ejection mode. When the mode is switched to the drop disk ejection mode, the disk transport means 16 is kept at the home position, and the core rod mechanism 15 once lowered is raised.

The core bar mechanism 15 is raised, and the holding arm is returned to the home position at the timing when the disk receiving seat 14 passes the plate 12.
(A) When falling off in a forward tilted posture In a forward tilted posture where one end of the disk D1 is hung on the rear arm 5, the disk D1 is not supported by the rear arm 5 due to the backward movement of the rear arm 5. With the other side as a fulcrum, the whole rides on the disc seat 14 that is falling and rising.

  At this time, the disk D1 may be supported on the disk receiving seat 14 in a normal state with the center hole 21 fitted into the center shaft 13. Alternatively, when the center hole 21 is disengaged from the center shaft 13, it is supported by the end of the disk receiving seat 14 and the center shaft 13 as shown in FIG.

  The core rod mechanism 15 rises to the disk replacement reference position and stops with such a disk D1 placed. Next, the disk transport means 16 moves from the home position toward the disk holding position. Here, the disk transport means 16 advances horizontally toward the rear side.

  In the course of the movement of the disc transport means 16, the inclined surface 19 a of the inclined member 19 interferes with the end of the disc tilted on the disc seat 14, and the disc end rises while contacting the inclined surface 19 a. Thus, the position of the disk D1 is moved little by little, and the position on the disk receiving seat 14 is corrected.

  In the course of this correction, the center hole 21 coincides with the center shaft 13 and is placed on the disk receiving seat 14 in a normal posture that can be transported by the disk transport means 16 (FIG. 13). Alternatively, even when the center hole 21 does not coincide with the center shaft 13, the end of the disk D <b> 1 is positioned between the facing member 20 and the inclined member 19 along the inclined surface 19 a.

  In any case, in a state where the disk transport means 16 has moved to the disk gripping position, the disk transport means 16 grips the end of the disk D1. Next, the disk D1 can be discharged from the disk receiving seat 14 by lowering the core bar mechanism 15 and driving the base roller 18.

(B) When falling off in a backward tilted posture In a rearward tilted posture in which one end of the disk D1 is hung on the front arm 11 as shown by a two-dot chain line in FIG. Since it is no longer supported by the forearm by retreating, the whole rides on the disk receiving seat 14 that is tilting up with the other side as a fulcrum.

  At this time, the disk D1 may be supported on the disk receiving seat 14 in a normal state with the center hole 21 fitted into the center shaft 13. Alternatively, when the center hole 21 is disengaged from the center shaft 13, it is supported by the end portion of the disk receiving seat 14 and the center shaft 13 with a tilt opposite to that shown in FIG. It has become.

The core rod mechanism 15 rises to the disk replacement reference position and stops with such a disk D1 placed. Next, the disk transport means 16 moves from the home position toward the disk holding position.
In the process of moving the disc transport means 16, the front end portion of the disc D <b> 1 in the backward inclined posture enters between the inclined member 19 and the opposing member 20.

  In the state where the disk transport means is moved to the disk holding position, the disk transport means 16 grips the end of the disk D1. Next, the disk D1 can be discharged from the disk receiving seat 14 by lowering the core bar mechanism 15 and driving the base roller 18.

  As described above, according to the present invention, when the disc is ejected, the disc is held in advance by the holding arm, the disc transport means is displaced to the disc holding position, and the disc is picked up by the disc transport means. The center shaft is removed from the center hole of the disk by lowering it from the reference position toward the standby position, and should be ejected by the disk transport means. It is possible to transport the disc by means of the disc carrier, which is scooped by the disc holder and tilted on the disc holder, with a part of the disc carrier moving from the home position toward the holding position interfering with the disc. Since it is configured to be corrected to the posture, the disk that has failed to be held by the holding arm and dropped from the disk seat is automatically Effect that can be discharged to.
