Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disk pack that accommodates a plurality of disks, and a selected one of the disks accommodated in the disk pack is attached to a disk mounting portion. The present invention also relates to a disk player with a disk changer, which is equipped with a disk changer mechanism that performs a series of operations for returning a disk from a disk mounting portion to a disk pack.

BACKGROUND OF THE INVENTION A disk player with a disk changer is known which is equipped with a disk changer mechanism that allows changing of the disks mounted on a disk mounting part within the range of a plurality of prepared disks. The disk changer mechanism installed in such a disk player can accommodate a plurality of disks, and a disk pack formed as an independent mechanism is removably attached to perform the disk changing operation. There are things that have been done.

In a disk player equipped with a disk changer mechanism to which such a disk pack is attached, for example, a plurality of disks are supported parallel to each other and stored in stacks with minute gaps in the vertical direction. The disk pack is attached, and the disk changer mechanism attaches a selected one of the plurality of disks stored in the disk pack to the disk attachment part, that is,
When performing a loading operation, or an operation of removing the disk attached to the disk mounting part from the disk mounting part and storing it in the disk pack, that is, an unloading operation, there is a means for taking out the disk from the disk pack, and a means for removing the disk from the disk mounting part. The entire disk transport section of the disk changer mechanism, which is composed of means for removing the disk from the disk pack, drive rollers for moving the disk from the disk pack to the disk mounting section, or from the disk mounting section to the disk pack, is connected to the disk pack. The disc pack is moved up and down on the side of the opening for inserting or removing the disc. This vertical movement of the entire disk pack transport section is performed by placing the disk on the disk mounting section and moving the disk in order to find a storage stage in order to take out a selected disk from among the plurality of disks housed in the disk pack. This is done to remove the disk from the disk mounting section, or to search for a storage stage for a disk pack to which the disk removed from the disk mounting section should be returned.

By the way, as mentioned above, in a disk player with a disk changer in which the entire disk transport section of the disk changer mechanism is configured to move up and down with respect to the attached disk pack, there are problems as described below. . That is, if a disk pack is ejected from the disk changer mechanism during loading or unloading operation of the disk changer mechanism or during information reproduction from the disk, the This causes inconveniences such as damage to the disk, or there being no place to return the removed disk.

Further, when the disk transport unit moves up and down relative to the disk pack on the side of the opening of the disk pack, the disks stored in the disk pack are considered to be in an incomplete storage state and cannot be properly stored in each storage stage. When the disk is not placed in the position and a part of the disk protrudes from the opening, the portion of the disk that faces the opening of the vertically moving disk transport section is attached to the disk that protrudes from the opening of the disk pack. There is a risk that the disks will collide or come into contact with each other, causing damage to the disk, and that the loading or unloading operation may be hindered.

In particular, when the disk is returned to a predetermined storage stage of the disk pack due to the unloading operation, the disk is not fully stowed and a portion of it protrudes from the opening of the disk pack, and the loading operation then stops. When this is done, the above-mentioned inconveniences are likely to occur.

Therefore, in order to eliminate this inconvenience, the disk changer mechanism is provided with a locking member for locking the disk pack, and the unlocking operation of this locking member is performed by a motor controlled by an electronic control section. By making this motor inactive during the loading operation of the disk changer mechanism, the disk pack cannot be ejected, while the disk inserted into the disk pack is moved to a predetermined storage position. At the same time, the disk changer mechanism is provided with a setting drive member for operating the setting member, and this setting drive member is driven by a motor controlled by an electronic control section, and this motor is configured to operate as required. It is conceivable that the disk inserted into the disk pack can be placed in the normal storage position by rotating the disk according to the rotation.

Problems to be Solved by the Invention However, if the unlocking operation of the locking member and the driving of the setting drive member are performed by separate motors as described above, two motors are required and the motor control system is two-way. Not only does this require a system, which complicates the configuration, but it also increases the cost of the disc player, and is also undesirable in terms of reducing the size and weight of the disc player.

In view of these points, the present invention provides a disk changer mechanism to which a disk pack having a disk setting member is mounted, which is provided with a locking member for locking the disk pack and a setting drive member for operating the setting member. The lock release operation and the driving of the setting drive member are performed by a single motor, compared to the structure in which the lock release action and the drive of the setting drive member are performed by separate motors. It is an object of the present invention to provide a disc player with a disc chain gear, which is simplified and can be made smaller and lighter in cost as well as in size and weight.

Means for Solving the Problems In order to achieve the above-mentioned object, a disk player with a disk changer according to the present invention has a disk storage section that independently accommodates a plurality of disks, and a disk inserted into the disk storage section. a setting member that operates to bring the disc pack to a predetermined storage position; a setting drive member that operates the above-mentioned setting member; a motor that selectively rotates in a forward direction or a reverse direction; and a setting drive member that receives the rotational driving force of the motor and rotates in a first direction or a second direction depending on the direction of rotation. an arm that rotates in a first direction; a drive gear that is rotatably supported by the arm and rotates in response to the rotational driving force of the motor; and when the arm rotates in a first direction, the drive gear and A first driven gear rotates in mesh with the drive gear, and a second driven gear rotates in mesh with the drive gear when the arm rotates in the second direction. Then, the lock member is unlocked in conjunction with the rotation of the first driven gear, and the second driven gear is rotated.
The setting drive member is driven to operate the setting member in conjunction with the rotation of the driven gear.

In the disk player with a disk chain gear according to the present invention configured as described above, for example, when the motor is rotated in the forward direction, the arm receives the rotational driving force in the forward direction of the motor and rotates in the first direction. The driving gear and the first driven gear mesh with each other, and the rotational driving force of the motor is transmitted to the first driven gear via the driving gear.
This causes the first driven gear to rotate, and the locking member is unlocked in conjunction with the rotation of the first driven gear. On the other hand, when the motor is rotated in the opposite direction, the arm rotates in the second direction in response to the rotational driving force of the motor in the opposite direction, and the driving gear and the second driven gear mesh with each other, causing the motor to rotate. The rotational driving force is transferred to the second
This causes the second driven gear to rotate, and in conjunction with the rotation of the second driven gear, the setting drive member that operates the setting member is driven, and the setting drive member is driven to operate the setting member in the disk storage section of the disk pack. The disk inserted is set in the normal storage position.

That is, the disk player with a disk changer according to the present invention is configured to selectively perform the unlocking operation of the locking member or the driving of the setting drive member depending on the rotational direction of one motor. Since it is not necessary to perform the lock release operation and drive the setting drive member at the same time, just by controlling one motor, the lock release operation can be performed without interfering with the original functions and operations of the disk player with disk changer. operation and driving of the setting drive member.

As a result, the disk D is moved to a position where a portion thereof protrudes from the opening 3, as shown by the dashed line in FIG. 3, and is placed in a position where it can be taken out.

The disk setting lever 7 and the slider 22 are driven by a disk changer mechanism in a disk player equipped with a disk changer, as described below, to which the disk pack 1 is mounted.

FIG. 4 is a perspective view showing essential parts of an example of a disk player with a disk changer according to the present invention, which is equipped with a disk changer mechanism to which the disk pack 1 described above is attached. The disc player with a disc chain gear of this example has a base chassis 27, and the base chassis 27 includes a disc mounting portion 28 that is rotationally driven by a spindle motor,
An optical pickup 29 is installed to read information signals from the disk D that is mounted on the disk mounting section 28 and rotated.The optical pickup 29 also constitutes a part of the disk changer mechanism, and the above-mentioned disk pack 1 is mounted thereon. A pack mounting stand 30 is installed. The pack mounting base 30 has a groove 14 (see FIG. 2) provided on the bottom of the disk pack 1.
A guide convex portion 31 that engages with is provided, and an ejecting lever 33 with a spring 32 stretched thereon is provided.

To attach disk pack 1 to the pack mounting base,
By engaging the groove 14 of the disk pack 1 with the guide protrusion 31 of the pack mounting base 30 and sliding the disc pack 1 on the pack mounting base 30 while pressing the eject lever 33 against the spring 32. It will be done. When the disk pack 1 reaches a predetermined mounting position, a locking member 35 protruding from the lower surface side of the pack mounting table 30 to the upper surface side through a through hole 34 provided in the pack mounting table 30 locks the disk pack position. It engages with the recess 15.
As a result, the disk pack 1 is placed on the pack mounting base 3.
Fixed to 0. At this time, the upward movement of the disk pack 1 is restricted by the holding plate 30a.

By the way, disk pack 1's pack mounting base 3
If ejection from 0 can be performed at all times, the above-mentioned inconvenience will occur. That is, during a loading operation in which the disk D is removed from the disk pack 1 and installed in the disk mounting section 28, during an unloading operation in which the disk D is removed from the disk mounting section 28 and returned to the disk pack 1, or during an information reproducing operation, etc. If the disk pack 1 is ejected from the pack mounting base 30, the disk D that is being inserted into or removed from the disk pack 1 may be damaged, or the ejected disk D may have no place to return to. This causes problems such as storage. Therefore, in this example, in order to prevent the disk pack 1 from being ejected during each of the above-mentioned operations, the operation of the locking member 35 is controlled by a motor that is controlled by an electronic control section. ing.

On the lower surface side of the disk pack mounting base 30, there is a lock release mechanism for releasing the lock on the disk pack 1 by the locking member 35 in order to eject the disk pack 1 from the pack mounting base 30, and a disk setting lever 7 of the disk pack 1.
A drive mechanism is installed to drive the Regarding these mechanisms, FIG. 1, which is a perspective view showing the bottom side of the pack mounting table 30, and FIG. 5, which is a schematic plan view showing the bottom side of the pack mounting table 30 seen through from the top side. Refer to and explain.

First, to explain the lock release mechanism, as clearly shown in FIG.
is installed by a shaft 36 on the bottom side of the pack mounting base 30.
It is rotatably supported, is biased by a spring 36a, projects to the upper surface side of the pack mounting base 30 through the through hole 34, and normally locks the disk pack 1. A lock release lever 37 that rotationally drives this lock member 35 is attached to the pack mounting base 3.
0 via a shaft 38. A protrusion 39 for rotationally driving the lock member 35 is provided at one end of the lock release lever 37, and an engagement pin 40 is provided at the other end, as shown in FIG.
is fixed, and this engages with a cam groove 42 provided in a first driven gear 41 that is pivotally attached to the pack mounting base 30. As shown in FIG. 5, the center of this cam groove 42 is located at the first driven gear 41.
Therefore, the first driven gear 41 is located at a position shifted from the rotation center of the arrow d in FIG.
When the lock release lever 37 rotates half a turn in the direction shown, the lock release lever 37 moves downward, and its protrusion 39 moves into the fifth position.
It moves from the position shown by the solid line to the position shown by the dashed-dotted line in the figure. As a result, locking member 3
5 is pushed down by the inclined edge formed on the protrusion 39 of the lock release lever 37, and sinks into the lower surface of the pack mounting base 30. Therefore, when such an operation is performed while the disk pack 1 is fixed to the pack mounting base 30, the disk pack 1 is released from the locked state and is pushed by the eject lever 33. It is ejected from the pack mounting base 30. In addition, a rack is provided on the side of the disk pack 1, and a rack is provided on the side of the disk pack 1.
A pinion is provided on the side, and this opion is connected to the motor,
For example, the disk pack 1 may be ejected by being driven by a motor 58, which will be described later.

Next, to explain the drive mechanism that drives the disk setting lever 7 of the disk pack 1, a drive lever 43 that rotates the disk setting lever 7 is attached to the pack mounting base 30 via a shaft 44. It is supported on the lower surface side, and a drive pin 45 is implanted at one end thereof. The drive pin 45 protrudes from the bottom side to the top side of the pack mounting base 30 through a through hole 46 provided in the pack mounting base 30, and as shown in FIG. It is adapted to engage with the driven piece 11 of the disk setting lever 7. An engagement pin 47 is fixed to the other end of the drive lever 43, and engages with a cam groove 49 provided in a second driven gear 48 that is pivotally attached to the pack mounting base 30. The center of this cam groove 49 is also located at a position shifted from the rotation center of the second driven gear 48, and therefore,
When the second driven gear 48 makes a half turn in the direction shown by the arrow e in FIG. Move to the position indicated by the dashed line. As a result, the pack mounting base 30
The disk setting lever 7 of the disk pack 1, which is attached to the disk pack 1, rotates in the direction to bring the disk D to the normal storage position in the disk storage section 4.

Further, the second driven gear 48 is provided with a cam groove 51 similar to the cam groove 49, as shown in FIG. 5, on a surface opposite to the surface on which the cam groove 49 is provided. A slider setting lever 52 for setting each slider 22 of the disk pack 1 in a predetermined position all at once is supported on the lower surface side of the pack mounting base 30 via a shaft 53, and a lever fixed to one end thereof. The matching pin 54 engages with the cam groove 51 of the second driven gear 48 . The other end of the slider setting lever 52 is located at a position where it can be bent from the bottom side of the pack mounting base 30 and engaged with each slider 22 of the disk pack 1 mounted on the pack mounting base 30. A drive lever 55 is provided that extends to. With this configuration, when the second driven gear 48 rotates half a turn in the direction indicated by the arrow e in FIG. 5, the slider setting lever 52 rotates accordingly, and the drive lever 55 It moves from the position shown by the solid line to the position shown by the dashed-dotted line in FIG. As a result, each slider 22 of the disk pack 1 mounted on the pack mounting base 30
are set all at once at a predetermined position (the position indicated by the solid line in FIG. 3).

The rotational drive by the first and second driven gears 41 and 48 described above, that is, the rotational drive for the lock release lever 37, the drive lever 43, and the slider setting lever 52, is performed by the gears 56 and 57.
This is performed by one motor 58 via the motor 58. To explain this, a gear 56 is pivotally attached to the lower surface side of the pack mounting base 30.
An arm 59 is rotatably supported by the gear 56. A shaft 60 is fixed to the tip of the arm 59 so as to protrude from both sides of the arm 59.
A gear 57 is rotatably supported on a portion of the shaft 60 that protrudes from one surface of the arm 59, and the portion that protrudes from the other surface is shown in FIGS. 4 and 5. As shown, pack mounting base 3
It is located in a through hole 61 provided at 0. Although not specifically shown here, the arm 59 and the gear 56 engage with each other via a friction member. Further, the gear 57 meshes with the large-diameter tooth portion 56a of the gear 56, and the worm gear 56b of the gear 56 meshes with the worm 62 rotated by the motor 58.

With this configuration, when the gear 56 is rotated in the counterclockwise direction in FIG. 5 by normal rotation of the motor 58, the arm 59 engaged with the gear 56 via the friction member The shaft 60 rotates counterclockwise in FIG. 5 along with the gear 56, and stops at a position where the shaft 60 is restricted from moving by the through hole 61, as shown by the solid line in FIG. As a result, the gear 57 meshes with the first driven gear 41, and the first driven gear 41 is moved by the arrow d in FIG.
It is rotated in the direction shown. In this case, the first driven gear 41 is configured to rotate only once. That is, provided in the first driven gear 41,
When the switch 63 (Fig. 5) operated by the notched flange portion 41a, which is partially cut out, is turned from the off state to the on state by the rotation of the first driven gear 41, and then is turned off again. , the rotation of the motor 58 is stopped. As the first driven gear 41 rotates once in this manner, the lock release lever 37 takes the position shown by the dashed line in FIG. 5, and then returns to the original position shown by the solid line.

On the other hand, the motor 58 is reversed and the gear 56 is in the fifth position.
When the arm 59 is rotated in the clockwise direction in the figure, the arm 59 rotates in the clockwise direction in FIG. The driven gear 48 is rotated in the direction shown by arrow e in FIG. In this case as well, the second driven gear 48 rotates only once, as described above, and in this case, the switch operated by the notch flange 48a provided on the second driven gear 48 When the motor 64 is turned from the on state to the off state and then turned on again, the rotation of the motor 58 is stopped. In this way the second
When the driven gear 48 rotates once, the drive lever 43 and the slider setting lever 52 take the position shown by the dashed line in FIG. 5, and then return to the original position shown by the solid line.

An example of a disk player with a disk changer according to the present invention, in which the disk pack 1 mounted on the disk pack mounting base 30 is ejected and the disks accommodated in the disk pack 1 are set in the normal storage position as described above. , a series of steps are performed in which a selected one of the plurality of disks D accommodated in the disk pack 1 is taken out, it is installed in the disk mounting section 28, information is reproduced, etc., and then the disk is returned to the disk pack 1. The operations are performed by the members shown at 66-111 in FIG. To briefly describe this, in order to take out the disk D housed in the disk pack 1, a slider 2 is installed on the disk pack 1.
A slider driving means for driving the movable chassis 6 is provided.
has a slide lever 67 attached to 6,
This slide lever 67 is provided with a projecting piece 68 for driving the driven piece 26 of the slider 22. Therefore, as shown in FIG. 6, when the slide lever 67 is moved in the direction indicated by the arrow f, the protruding piece 68 moves against the slider 2.
2 from the position shown by the solid line to the position shown by the dashed line.
The inner disk D is pushed by the slider 22, as shown by the dashed line in FIG.
It is moved into the opening 3 of the disk pack 1. The movement of the slide lever 67 is caused by a gear mechanism consisting of a roller 70, gears 72 and 76, an arm 73, shafts 74 and 79, a through hole 75, a partially toothed gear 69, etc., and a motor that drives this gear mechanism. For example, when the motor 77 rotates in the normal direction, the partially partially toothed gear 69 rotates in the normal direction, and the slide lever 67 moves in the direction of the arrow f in FIG.
When the motor 77 is rotated in the reverse direction, the partially partially toothed gear 69 rotates in the opposite direction, and the slide lever 67 returns to its original position and stops. Further, the motor 77 remains in an operating state even after the movement of the slide lever 67 has stopped, and thereafter rotates only the drive roller 91.

Here, the disk pack 1 is mounted and fixed on the pack mounting base 30 of the disk changer mechanism, and in order to take out the selected disk D in the disk pack 1, the slide lever 67 is moved to remove the selected disk D. The entire movable chassis 66 is driven by a motor 83 to move the entire movable chassis 66 to the position where the slider 22 corresponding to the slider 22 is arranged. 84b, a spring 86, and the like, it is moved by a screw feeding mechanism. Note that the movable chassis 66 is formed with a through hole 66a and a bearing 111;
With the feed screw member 81 inserted therein, it is guided by the guide shaft 110 and is moved up and down in a direction substantially perpendicular to the disk mounting portion 28 . In this case, the optical position detection sensor 87 fixed to the movable chassis 66 reads the slit 89a of the position detection plate 89 to detect the position, and thereby the movable chassis 66 and the slide lever 67
is precisely moved to the desired position of the slider 22.

The movable chassis 66 also supplies the disk D taken out from the disk storage section 4 of the disk pack 1 to the disk mounting section 28, and also removes the disk D mounted on the disk mounting section 28 and stores the disk pack there. 1, drive roller 91, driven roller 92, support plate 93, link member 94, stopper pin 95, and guide roller 10.
Further, the movable chassis 66 includes a clamp arm 96, its rotating shaft 96a, and an upper flange portion 9.
7a and a clamping member 97 having a lower flange 97b, a spring 98, etc., is provided.

In the disk player with a disk changer according to the present invention configured as described above and equipped with a disk changer mechanism to which the disk pack 1 is mounted, the disk pack 1 containing a plurality of disks D is mounted on the pack mounting base 30. Each time the disk pack 1 is installed, it is locked by the locking member 35, and the drive lever 43 and slider setting lever 52 are rotated by the motor 58 as described above. As a result, the disk setting lever 7 is driven, and each disk D inserted into the disk pack 1 through its opening 3 is stored in the normal storage position in each storage stage, and each slider 22 are aligned in an inoperative position that maintains each disk D in its normal storage position. When the disk D to be used for information reproduction is designated, the motor 83 rotates, thereby causing the movable chassis 6
6 is raised or lowered, and the slide lever 67 is moved to the position of a specific slider 22 corresponding to the selected disk D. In this state, the motor 77 is started, the slide lever 67 is driven, and the slider 22 corresponding to the selected disk D is thereby moved from the non-operating position, and the selected disk D is moved to the opening position. 3 from the disk pack 1. Then, the taken-out disk D is driven by the drive rollers 91 and 92 in a direction along its surface, and is moved to a position corresponding to the disk mounting section 28. In this case, the other end of the clamp arm 96 comes into contact with the outer peripheral edge of the disk D to prevent the disk D from tilting upward.

When the disk D that has been transported to the position corresponding to the disk mounting portion 28 reaches a position where it abuts the large diameter portion of the stopper pin 95, this is detected by an optical sensor (not shown), and the disk D is moved based on the detection result. The chassis 66 is lowered. As a result, the disk D is lowered toward the disk mounting section 28 and is mounted on the disk mounting section 28.
Thereafter, the movable chassis 66 is further lowered. When the disk D is lowered to the position where it is attached to the disk attachment part 28, the link member 94 connected to the support plate 93 comes into contact with the head of the stopper member 94a, and the disk D is attached to the disk attachment part 28.
After the movable chassis 66 is mounted, the movable chassis 66 is further lowered, thereby separating the driving roller 91, the driven roller 92, the guide roller 100, etc. from the disk D mounted on the disk mounting portion 28. At the same time, the other end of the clamp arm 96 contacts the stopper member 102 and rotates, and the clamp member 97 clamps the disk D to the disk mounting portion 28 . Then, the movable chassis 66 operates the leaf switch 103 (FIG. 4) to turn on the motor 83.
The rotation of the movable chassis 66 is stopped, and the lowering movement of the movable chassis 66 is stopped, and a state is reached in which the optical pickup 29 can read the information signal from the disk D. In this state, the disk D is no longer in contact with the large diameter portion of the stopper pin 95, and its outer peripheral edge is in a position facing the small diameter portion of the stopper pin 95. Therefore, the disk D can rotate without contacting the stopper pin 95.

Thereafter, when the reading of the information signal from the disk D by the optical pickup 29 is completed and the disk D is to be returned to the disk pack 1, the movable chassis 66 is raised by the rotation of the motor 83. As a result, the disk D is removed from the disk mounting section 28, and the drive roller 9 is again removed.
1 and the driven roller 92 and raised. When the disk D reaches the position corresponding to the original storage stage in the disk pack 1, the movable chassis 66 is stopped from rising.

Then, when the disk D is moved to the position corresponding to the original storage stage in the disk pack 1,
The motor 77 rotates in the opposite direction to that in the above case, and as a result, the slide lever 67 is returned to its original position, and the disk D is conveyed to the disk pack 1 side by the drive roller 91 and the driven roller 92, and the It is moved to the position shown by the two-dot chain line in FIG. When the disk D reaches this position, it is detected by an optical sensor (not shown), and the motor 5 is activated based on the detection result.
8 is started. As a result, the drive lever 43 and the slider setting lever 52 are driven, and as a result, the disk D is returned to its normal storage position in the original storage stage, as shown by the solid line in FIG. The slider 22 corresponding to D is returned to its original position. After that, rotation of the motor 77 is stopped.

Then, with the disk D stored in the normal storage position and the slider 22 returned to its original position as described above, if, for example, the eject button provided on the operation panel section (not shown) is operated,
The motor 58 rotates in the opposite direction to the direction in which the drive lever 43 and the slider setting lever 52 are driven, and the lock release lever 3 is rotated as described above.
7 is driven to release the lock member 35, and the disk pack 1 is ejected by the elasticity of the spring 32.

In this manner, loading and unloading operations and ejecting of the disk pack by the disk changer mechanism are performed.

Effects of the Invention As is clear from the above description, the disk player with a disk changer according to the present invention has one motor installed in the pack attachment part of the disk changer mechanism to which a disk pack containing a plurality of disks is attached. By selectively rotating this motor in the forward or reverse direction, the locking member that locks the disc pack in the pack mounting portion is unlocked, and the disc provided in the disc pack is brought to a predetermined storage position. The setting drive member for operating the setting member for closing can be selectively driven depending on the direction of rotation of the motor. Therefore, by simply controlling the rotation of one motor, the locking member can be unlocked as necessary, and the disk pack can be unlocked when the disk changer mechanism is loading or unloading, or when reproducing disk information. It is possible to prevent the disk from being undesirably ejected from the disk mounting part of the disk changer mechanism, and also to operate the setting member provided on the disk pack to prevent the disk from being stored in the disk pack in an incompletely stored state. This can prevent the product from being left unattended.

Therefore, the configuration can be simplified compared to a system in which the unlocking operation and the driving of the setting drive member are performed by separate motors, respectively.
This makes it possible to reduce costs, and furthermore, to reduce the size and weight.
