Description

  The present invention relates to a disk changer apparatus having a mechanism for selecting a desired disk from a large number of stacked and held disks and conveying the selected disk to a disk drive.

  An example of a conventional disk loading apparatus having a disk rack that accommodates disks in a plurality of disk receiving grooves substantially vertically is described in Patent Document 1. In the disk loading device described in this publication, the disk receiving groove length of the disk rack is increased to about half of the outer periphery of the disk to hold the lower left half of the disk, and moved to the disk stacking direction on the right side of the disk rack. Possible disk drive body is arranged. An arc-shaped loading arm whose one end is rotatable is attached to the upper left end of the disk drive main body.

  The upper end portion of the disk rack is used as a positioning portion, and is a two-row positioning portion having a width twice that of the disk receiving groove. By selecting one of the two rows of positioning portions, the disk receiving groove and the disk drive main body are positioned relative to each other, and the disk is loaded onto the disk drive by the loading arm.

  Patent Document 2 describes that a disk accommodated in a disk rack similar to Patent Document 1 is loaded from below by a loading arm. At that time, the loading arm is formed with a groove extending to the open end side, and the disk is held in this groove, and the protrusion provided on the side of the groove prevents contact with other disks due to the falling of the disk. Yes.

Japanese Patent Application Laid-Open No. 08-241559 JP-A-11-162083

  In the disk loading apparatus described in Patent Document 1, the rotation end of the loading arm is provided at the upper corner of the disk drive main body, and the positioning part is provided at the upper end of the disk rack. Therefore, the positional deviation of the selected disk and the leading end of the loading arm in the disk stacking direction can be reduced, and the loading arm can be substantially aligned with the selected disk.

  However, since this loading arm guides the optical disk from the outside of the optical disk to the inside of the disk drive main body, its length is about the diameter of the optical disk and moves in the disk rack for a long distance. Further, since the disk is held by the disk rack located below the disk, the length of the disk rack in the vertical direction is long and a deep groove must be formed.

  That is, the configuration of the loading arm and the groove of the disk rack through which the loading arm passes is such that a part of the loading arm is positioned in the groove of the disk rack until the disk is almost pushed out to the disk drive body. As a result, the depth of the groove of the disk rack is increased, and the partition portion for forming the groove is elongated, making it difficult to manufacture the resin rack at low cost by injection molding. In order to avoid this problem, if the partition part and the member constituting the groove bottom face are separated, the number of parts increases.

  On the other hand, in the disk reproducing apparatus described in the cited document 2, the groove of the lifter arm for loading the disk is widened toward the opening side and is in contact with the disk. However, the loading arm is positioned on the desired optical disk. There is no disclosure.

  The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to pick up a desired disk from a plurality of disks stacked on a disk cassette and deliver it to a disk storage unit in a disk changer. The push lever is easily positioned with a simple configuration. At the same time, it is an object to prevent the pushing lever for pushing out the disc from passing through the disc holding portion of the groove formed in the disc cassette.

  In order to achieve the above object, the present invention is characterized in that a cassette for laminating and holding a plurality of discs, a disc drive section for recording or reproducing on a disc selected from a plurality of discs laminated in the cassette, and the cassette A disc changer device having a disc picker having a disc picker that picks up the disc from the disc drive and conveys the disc to a disc drive unit.The disc picker holds a disc and conveys the disc. An extruding lever for extruding the selected disc from the cassette, the extruding lever having a disc catcher that contacts and holds the disc, and a guide rib provided on the back side at the tip of the disc catcher, The cassette includes the plurality of cassettes. A guide groove member having a lower disk storage member in which a disk storage groove for holding the lower portion of the disk is formed, and a guide groove that is continuous with the disk storage groove and through which only the guide rib can pass is formed in the lower disk storage member It is in having established.

  According to the present invention, in the disk changer device, the guide rib is provided on the back side of the front end of the push lever, and the guide groove is provided on the cassette side. Therefore, the push lever can be positioned easily and accurately with a simple configuration.

  Other features and functions of the present invention will become apparent from the following detailed description.

  Several embodiments of the disk changer apparatus (disk library apparatus) according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the disk changer device 100, in which a cover that covers an outer peripheral portion is removed. The disc changer device 100 according to the present embodiment is mainly used as a storage device (library device), and a large number of optical discs 50 such as DVD and Blu-ray (registered trademark), for example, 100, are arranged vertically. A pair of storable disk cassettes 41 and 42 are detachably held.

  The disk changer device 100 has a rectangular parallelepiped shape that is long in the stacking direction of the optical disks 50, and one end in the longitudinal direction forms a drawer and insertion direction opening for the disk cassettes 41 and 42. When the disk cassettes 41 and 42 are pulled out and inserted, knobs 41a and 42a formed on the front surfaces of the respective disk cassettes 41 and 42 are used.

  Each of the disk cassettes 41 and 42 stores a disk in the same manner as the upper disk storage member 44 formed with a disk storage groove 44a (see FIG. 2) for holding the optical disk 50 in order to hold the optical disk 50 substantially vertically. And a lower disk storage member 46 in which a groove 46b is formed. The upper disk storage member 44 and the lower disk storage member 46 are connected by support plates 43 provided at a plurality of positions in the longitudinal direction of the disk cassettes 41 and 42, and store the optical disk 50 while keeping the vertical position constant. A disk storage portion 48 is formed.

  A front surface portion in which an opening for storing and taking out the disk cassettes 41 and 42 forms a front operation portion 14 of the disk changer device 100. Further, a chassis 13 is disposed below each disk cassette, and the disk cassettes 41 and 42 can be placed and held.

  The other end portion in the longitudinal direction of the disk changer device 100 constitutes a back panel portion 15 to which a cooling fan (not shown) is attached. Disc drive units 11 and 12 are provided between the back panel unit 15 and the disc cassettes 41 and 42. The disk drive units 11 and 12 rotate and drive the optical disk 50 transported by the disk transport mechanism 20, which will be described in detail later, to reproduce or record information stored on the optical disk 50. A space through which the optical disk 50 can pass is formed between the disk cassettes 41 and 42 so that the optical disk 50 can be transported to the disk drive units 11 and 12, and the space between the disk drives 11 and 12 at the end in the longitudinal direction is A disk delivery position 51 is configured.

  A disk transport mechanism 20 is provided for extracting a desired optical disk 50 a from the disk cassettes 41 and 42 from a plurality of stacked optical disks 50 and transporting them to one of the disk drive units 11 and 12. The disc transport mechanism 20 includes a guide rail plate 21 extending in the longitudinal direction of the disc changer device 100 from the back side of the front operation unit 14 to the front side of the back panel unit 15, and a disc picker 29 movable along the guide rail plate 21. And have.

  The guide rail plate 21 mainly has a guide rail body 21a whose side surface is used as a guide portion 21b. The disc picker 29 has a picker arm 24, the center of which is located below the guide rail plate 21 and extends to the outside in the left-right direction of the lower disc storage member 45 of the disc cassettes 41, 42. ing. Further, push levers 25 extending downward are rotatably provided at both left and right ends of the picker arm 24.

  A plurality of guide rollers 27 are provided on the upper surface of the picker arm 24 in the vicinity of the guide rail plate 21 with the guide rail plate 21 interposed therebetween. As the guide roller 27 moves along the guide rail plate 21, the disc picker 29 moves in the longitudinal direction of the disc changer device 100. In order to detect the position of the disk picker 29, a linear encoder 22 is disposed below the picker arm 24, and a sensor for detecting the linear encoder 22 is provided in the disk picker 29.

  FIG. 2 is a perspective view of the disk transfer mechanism 20 and the part related to the transfer by the disk transfer mechanism 20 extracted from the disk changer device 100 shown in FIG. The optical disk 50 held by the upper disk storage member 44 and the lower disk storage member 46 is partly omitted in FIG. 2, but is actually stored in all the disk storage grooves 46b (see FIG. 1). ).

  Here, the lower disk storage member 46 includes a disk holding part 46a in which a groove 46b for holding the optical disk 50 is formed, and a guide groove member 46c connected to the disk holding part 46a. A guide groove 46d is formed in the guide groove member 46c, and the guide rib 25d of the pushing lever 25 can pass through the guide groove 46d. The guide groove member 46c extends to the outside in the left-right direction with respect to the optical disc 50, and is spaced by a slight distance when the push lever 25 is not operated (see FIG. 3).

  FIG. 3 shows the disc picker 29 in a front view. A disc holding portion 28 is provided at the center and below the disc picker 29 in order to hold the optical disc 50 and transport it toward the guide rail plate 21. In order to deliver the optical disk 50 to the disk holding portion 28, the push lever 25 extending downward is attached to the end of the picker arm 24 as described above, and this is also a drive provided at the end of the picker arm 24. The motor 32 can be rotated by a predetermined angle. A stopper member 31 is provided on the side surface of the end of the picker arm 24 in order to limit the rotation of the push lever 25.

  The extrusion lever 25 is disposed inside the rod-like extrusion lever main body 25c, the disk catcher 25b disposed on the inner side of the extrusion lever main body 25c, and abuts when the contact between the extrusion lever 25 and the optical disk 50 ends. And a guide rib 25d to be described in detail later. Since the disc catcher 25b contacts the optical disc 50, it is preferable that the disc catcher 25b is made of a resin having a lower hardness than the optical disc 50 so as not to damage the surface of the optical disc 50.

  In the disc transport mechanism 20 configured as described above, the disc picker 29 having the picker arm 24 and the pushing lever 25 is moved to the desired optical disc 50 position in the longitudinal direction by using the linear encoder 22, and the pushing lever 25 is positioned. . Then, the pushing lever 25 is rotated by a predetermined angle using the drive motor 32. The push lever 25 comes into contact with the desired optical disc 50a and pushes the optical disc 50a toward the disc holding portion 28 side.

  Details will be described with reference to FIG. In FIG. 3, a state in which the desired optical disk 50a to be transported is accommodated in the right disk cassette 42 without operating the push lever 25 is indicated by a solid line. A state in which the push lever 25 is applied to the optical disk 50a is indicated by a broken line. A picker arm 24 extends in the horizontal direction on the outer side in the left and right direction of the disc holding unit 28 on which the optical disc 50a to be conveyed is held. The picker arm 24 extends further outward than the optical disk 50 placed on the lower disk storage member 46.

  An end portion of the picker arm 24 is configured to be bent downward, and a stopper 31 is attached to the lower end portion. A drive motor 32 with a speed reducer that rotationally drives the push lever 25 is disposed at the corners of the left and right ends of the picker arm 24. The drive motor 32 is controlled so that the drive motor 32 rotates the push lever 25 by an angle θ. Here, the angle θ is set to be equal to or larger than the rotation angle of the push lever 25 from the state where the push lever 25 is not operated to the state where the optical disk 50a is separated from the push lever 25.

  The position 25x of the push lever 25 is a state immediately after contacting the desired optical disc 50a, and the position 25y of the push lever 25 indicates a state when the push lever 25 is separated from the optical disc 50. When the pushing lever 25 starts to come into contact with the optical disc 50a, it comes into contact with the vicinity of the upper end of the disc catcher 25b attached to the pushing lever 25. In other words, the upper end portion of the disc catcher 25b is required to be at a height position higher than the position where it abuts on the optical disc 50a when the abutment starts.

  In the state where the pushing lever 25 is separated from the optical disc 50, as can be seen from FIG. 3, the contact position moves to the end face side of the disc catcher 25b, not to the longitudinal surface of the disc catcher 25b. Therefore, in this embodiment, in order to prevent the optical disk 50 from being damaged due to contact on the end face side, and to prevent the contact position from changing at a steep angle, the substantially circular (columnar) contact portion 25a is provided. Forming.

  A disc delivery means 53 is attached to a shaft 54 extending in the left-right direction in the disc holding portion 28 in order to receive the optical disc 50a moved to the optical disc 50y position by changing the position of the push lever 25y. A drive motor 52 provided in the vicinity of the upper corner of the disk holding unit 28 drives the disk delivery means 53 in the longitudinal direction (left-right direction) of the picker arm 24. As a result, the disk 50 a is positioned at the center in the left-right direction of the disk holding unit 28, held by the disk delivery means 53, and conveyed to the disk drive units 11 and 12.

  In the above configuration, the lower end position of the pushing lever 25 is set to a height position at which the contact with the optical disc 50a is completed when almost half of the optical disc 50a reaches the disc holding portion 28. This prevents an excessive load from being applied to the optical disc 50a from the push lever 25 side, and enables smooth delivery to the disc delivery member 53. In the unlikely event that the pushing lever 25 rotates above the position 25y at which the abutment ends, the abutment portion 25a and the guide rib 25d are formed in a shape that does not abut against the optical disc 50a again.

  Next, the operation of the disc catcher 25b provided on the pushing lever 25 will be described with reference to FIGS. 4 is a perspective view of the pushing lever 25 part in a state where the pushing lever 25 is not operated, and FIG. 5 is a front view of the pushing lever 25 part, which is the same as the right half of FIG. 6A and 6B are perspective views of the push lever 25 when the push lever 25 is operated. 7 and 8 are cross-sectional views illustrating how the guide rib 25d enters the guide groove 46d.

  In FIG. 4, when the pushing lever 25 is not operated, the pushing lever 25 is in a state of hanging substantially vertically. On the other hand, the optical disk 50 is held by the upper disk storage member 44 and the lower disk storage member 46 and is separated from the push lever 25. The lower disk storage member 46 includes a disk holding part 46a in which a groove 46b mainly holding the optical disk 50 is formed, and a guide groove member 46c extending in a mountain shape obliquely above the disk holding part 46a and having a guide groove 46d. It is composed of

  The guide groove 46d is a continuous groove on the same plane as the disk holding groove 46b, and the groove width and groove pitch of the guide groove 46d are the same as the groove width and groove pitch of the disk holding groove 46b. When the push lever 25 rotates around the output shaft of the drive motor 32 and comes into contact with the optical disk 50, the guide rib 25d provided on the back side of the front end of the push lever 25 first passes through the guide groove 46d.

  That is, when the drive motor 32 starts to drive the push lever 25, the push lever 25 rotates around the output shaft of the drive motor 32. Then, before reaching the position 25x in FIG. 5, which shifts from the state of FIG. 6A to the state of FIG. 6B, the tip of the push lever 25 faces the end surface of the guide groove member 46c. At that time, as shown in the front view of FIG. 5, only the triangular guide rib 25d formed on the back side extending downward as compared to the circular contact portion 25a of the push lever 25 is provided in the guide groove 46d. The lower side of the contact portion 25a and the guide rib 25d is formed in a mountain shape. At the same time, the upper end surface of the guide groove member 46c increases in height toward the outside (right side in FIG. 5) so that the circular contact portion 25a does not enter the guide groove 46d even when the push lever 25 rotates. It is low.

  The manner in which the guide rib 25d passes through the guide groove 46d will be described with reference to FIGS. 7 and 8 are both before the state shown in FIG. 6A. FIG. 7 shows a state where the pushing lever 25 is positioned with an error with respect to the guide groove 46d. Even if the disk transport mechanism 20 is positioned using the linear encoder 22, as described above, the push lever 25 may be positioned with an error from the position facing the guide groove 46d due to an assembly error or a processing error. . Therefore, the position is corrected by using the guide rib 25d and the guide groove 46d on the back side of the push lever 25.

  When the disk picker 29 is positioned using the linear encoder 22, the push lever 25 continues to rotate. A guide rib 25 d provided on the back side of the end of the push lever 25 approaches the guide groove member 46 c of the lower disk storage member 46. In the guide groove member 46c, the guide groove 46d is formed by the partition plate portion 46f. If the guide rib 25d is not positioned in the extension lines 46b1 and 46b2 including the boundary of the guide groove 46d, the guide rib tip 25d is formed on the partition plate portion 46f. collide.

  Here, the tip of the guide rib 45d has a tapered shape that is cut off obliquely. On the other hand, a chamfered portion 46g is formed at the tip of the partition plate portion 46f. When a part of the tapered surface at the tip of the guide rib 45d comes into contact with the chamfered portion 46g of the partition plate portion 46f, the tapered surface and the chamfered portion 46g are connected. As a guide, the guide rib 25d is guided in the stacking direction of the optical disc 50. At this time, since the push lever 25 continues to rotate, the guide rib 25d moves obliquely as a whole as shown in FIG. Then, it goes straight along the guide groove 46d. The width of the guide rib 25d is almost the same as the width of the guide groove 46d so that the push lever 25 moves straight in the guide groove 46d without swinging left and right, and the disc catcher 25b can face the optical disc 50. In consideration, it is preferable that the width is slightly smaller than the width of the guide groove 46d. By this operation, the disc catcher 25b can abut on the disc 50 accurately.

  Since the guide rib 25d is for positioning the disc catcher 25b, the guide rib 25d and the disc catcher 25b need to maintain the same positional relationship. Therefore, it is desirable that the position of the disc catcher 25b can be finely adjusted in the stacking direction of the optical disc 50 together with the guide rib 25d. In order to finely adjust the position of the disk catcher 25b, a method shown in FIG. 10B described later or a method of adjusting the position in the optical disk stacking direction at the mounting portion of the push lever 25 with a spring or the like is used.

  Next, the contact state between the disc catcher 25b and the disc 50 will be described with reference to FIGS. 6A and 6B and FIGS. 9 and 10A. FIG. 9 is a cross-sectional view showing a state in which the disc catcher 25b is in contact with the disc 50a. FIG. 10A is a perspective view of the push-out lever 25, with the contact portion (disc catcher 25b) on the top surface.

  FIG. 9 shows a state in which the push lever 25 has rotated to reach the push lever moving position 25x (see FIG. 3). The extrusion lever 25 includes a highly rigid extrusion lever main body 25c and a disc catcher 25b formed with a back groove 117 into which one side of the extrusion lever main body 25c can be fitted.

  The disc catcher 25b is composed of a disc catcher main body 111, and a concave groove 116 for loosely fitting a desired disc 50a is formed on the front side. The groove 116 is formed of a groove bottom surface 115 with which the disk 50a abuts and an inner side surface 113 for widening the opening end side. The outer peripheral surface of the disc catcher main body 111 has an outer surface 112 and a tip inclined surface 114 that forms a tapered portion continuous with the outer surface 112.

  When the pushing lever 25 rotates, the groove bottom surface 115 of the disc catcher 25b comes into contact with the disc 50a. As the push lever 25 continues to rotate, the disc catcher 25b moves in the direction of the arrow in FIG. At this time, the disk 50a is held in the groove 116 while the disk catcher 25b is in contact with the disk 50a.

  As described above, the guide rib 25d provided at the front end of the push lever 25 is guided by the guide groove member 46c of the lower disk storage member 46 while the push lever 25 is rotating before the disk catcher 25b comes into contact with the disk 50a. The guide groove 46d is formed in the guide groove 46d (see FIG. 6A). Thereafter, as the push lever 25 rotates, the guide rib 25d is guided by the guide groove 46d and advances in the guide groove 46d. On the other hand, the disc catcher 25b is guided to a position where it can come into contact with the disc 50 (50a). That is, when the disc catcher 25b starts to contact the disc 50 (50a), the guide rib 25d is guided in the advancing direction by the guide groove 46d. Therefore, the disc catcher 25b that moves integrally with the guide rib 25d is the groove 116 portion. It can contact the disk 50 (50a) accurately. As a result, the disk 50 (50a) that is in contact with the groove 116 is securely held in the groove 116.

  When the push lever 25 further rotates while the disc 50 is held by the disc catcher 25b, the guide rib 25d is detached obliquely upward from the guide groove 46d (see FIG. 6B). When the guide rib 25d is separated from the guide groove 46d, the effect of correcting the position of the disc catcher 25b by the guide groove 46d is lost. However, in this state, since the groove 116 of the disk catcher 25b already holds the disk 50 (50a), the movement of the disk 50 (50a) can be continued without any problem.

  In the conventional disk changer device that does not have the guide groove member 46c, there is no guide by the push lever 25. Therefore, the push lever 25 is rotationally driven while being attached to the drive motor 32 and moves circularly, and the optical disc 50 (50a). It was in contact with. For this reason, it has been difficult to automatically correct the positional deviation of the contact portion between the optical disc 50 (50a) and the push lever 25 until the push lever 25 comes into contact with the optical disc 50 (50a).

  As described above, in this embodiment, before the pushing lever 25 comes into contact with the optical disc 50a, the positional deviation of the pushing lever 25 is corrected by the guide groove 46d, and when the pushing lever 25 comes into contact with the optical disc 50a, the positional deviation occurs. It is possible to contact at a position where there is no gap. Further, since the guide groove member 46c and the tip of the push lever 25 are formed so that only the guide rib 25d can pass through the guide groove 46d, the load (sliding resistance) when the push lever 25 passes through the guide groove 46d can be reduced. .

  Another embodiment of the pushing lever 25 that can execute the position correction by the guide rib 25d more reliably will be described with reference to FIG. 10B. 10B is a view of the push lever 25, and is a cross-sectional perspective view taken along the line AA in FIG. 10A. In the present embodiment, the groove width of the groove 117 formed on the back side of the disc catcher 25b is made wider than the width of the pushing lever body 25c, and the spring 120 is placed in the gap formed between the groove 117 and the pushing lever body 25c. It is arranged. The springs 120 are disposed on both sides of the push lever body 25c. When no load is applied to the disc catcher 25b, the push-out lever main body 25c is positioned at the substantially central portion of the groove 117. With this mechanism, position correction in the stacking direction when the guide rib 25d passes through the guide groove 46d can be appropriately operated by deformation of the spring 120.

  In the embodiment described above, the disk changer device accommodates two disk cassettes. However, the present invention is not limited to a disk changer having two cassettes, but can be applied to a disk changer that stores only one cassette. Further, although the case of a cassette case in which optical disks are vertically stacked has been described, the present invention can also be applied to an apparatus that accommodates a cassette in which optical disks are horizontally disposed and stacked vertically.

  Furthermore, in the above embodiment, the cross-sectional shape of the disk catcher is a groove (V groove) shape having a tapered surface, but it may be a U-shaped groove shape or a shape having a flange portion on the disk contact portion side. The guide groove member of the lower disk storage member has a shape that decreases in height as it goes outward, but it may also have a constant height. However, in that case, it is necessary to change the push lever according to the shape.

  The present invention is not limited to the above-described embodiments, and can be implemented in various other forms. The above embodiments are illustrative in all respects. The scope of the present invention is indicated by the appended claims, and all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
