Description

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

2. Description of the Related Art Disc players equipped with a disc changer are known which are equipped with a disc changer mechanism that can replace a disc mounted on a disc mounting section within the range of a plurality of discs prepared.

A disc changer mechanism installed in such a disc player can accommodate a plurality of discs, and a disc pack formed as an independent mechanism is removably attached to the disc changer mechanism to perform disc changing operations. There is something.

In a disc player equipped with a disc changer mechanism to which such a disc puncture is installed, for example, a plurality of discs are supported parallel to each other and stored in stacks with minute gaps in the vertical direction. A disk puncture is installed, and the operation of loading a selected one of the plurality of disks stored in the disk pack into the disk loading section by the disk changer mechanism, that is, the loading operation, or the disk loaded in the disk loading section. means for removing the disc from the disc pack when an unloading operation is performed, in which the disc is removed from the disc mounting portion and placed in the disc pack;
The entire disk transport section of the disk changer mechanism consists of a means for removing the disk from the disk mounting section, a drive roller for moving the disk from the disk pack to the disk mounting section, or from the disk mounting section to the disk puncture. , the disk pack is moved up and down on the side of the opening provided in the disk pack for inserting or removing a disk.

This vertical movement of the entire disk transport section is performed by placing the disk on the disk mounting section and moving the disk in order to find a storage stage to take out a selected one of the plurality of disks accommodated in the disk puncture. This is done to remove the disk from the disk mounting section or to search for a storage stage of the disk pack to which the disk removed from the disk mounting section should be returned.

By the way, when a loading operation is performed in a disc player with a disc changer as described above,
First, it is necessary to pull out the selected disk from the disk pack and move the pulled out disk toward the disk mounting section. The mechanism that pulls out the disc selected from the punctured disc and moves it toward the disc mounting section is designed to operate quickly and reliably, and has a relatively simple configuration. It is hoped that this will be done. For this reason, the disk pack is provided with a slide member for pulling out the selected disk, and a slide lever for driving this slide member is provided on the disk transport section of the disk changer mechanism described above, so that when performing the loading operation,
After the disk transport section is moved up and down and the slide lever is moved to the position of the slide member corresponding to the selected disk, this is driven by a motor controlled by the electronic control section, and the above-mentioned disk transport is performed. A drive roller is provided in the section as a disk transport means for quickly moving the disk pulled out by the drive of the slide lever toward the disk mounting section, and this drive roller is driven by a motor controlled by an electronic control section. I can think of something to do. In this way, if the slide lever and the drive roller are driven by separate motors, and the rotation of each motor is controlled by the electronic control section, when the unloading operation is performed, the electronic control By rotating each motor in the opposite direction to the loading operation mentioned above, the slide lever can be returned to its original position, and a separate drive is also used to transport the disc from the disc mounting part back to the disc puncture. The loading operation can be carried out by the driving roller used in carrying out the above-mentioned loading operation, without providing a roller.

Problems to be Solved by the Invention However, if the slide lever and drive roller are driven by separate motors as described above, two motors and two motor control systems are required. This not only complicates the configuration, but 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 the above, the present invention provides a disc transport section of a disc changer mechanism in which a disc pallet equipped with a slide member for pulling out a disc is mounted, and a slide lever for driving the slide member, and a disc backing mechanism by driving the slide lever. A drive roller is provided to convey the disc pulled out from the disc toward the disc mounting section, so that the disc can be reliably and quickly pulled out from the disc puncture and mounted in the disc mounting section. The drive of the slide lever and drive roller is performed by a single motor, which simplifies the configuration and reduces costs, compared to a system in which the slide lever and the drive roller are driven by separate motors. A further object of the present invention is to provide a disc player with a disc changer that can be made smaller and lighter.

Means for Solving the Problems In order to achieve the above-mentioned object, a disc player with a disc changer according to the present invention accommodates a plurality of discs,
A puncture mounting part to which a disc back equipped with a sliding member for pulling out a stored disc is mounted; a disc mounting part to which a disc pulled out from the puncture mounting part is mounted; and a disc mounting part that moves up and down with respect to the disc mounting part. A movable chassis is provided. This movable chassis includes a slide lever that drives a slide member to pull out a selected disc from the disc back, a motor that selectively rotates in the forward or reverse direction, and a motor that rotates by receiving the rotational driving force of the motor. and a drive roller that moves the disc pulled out from the disc back in a direction along the surface thereof, and an arm that receives the rotational driving force of the motor and rotates in a first direction or a second direction depending on the rotation direction. a drive gear rotatably supported by the arm and rotates in response to the rotational driving force of the motor; and when the arm rotates in the first direction, the drive gear meshes with the drive gear and rotates in the positive direction by a predetermined angle. When the arm rotates in the second direction, it meshes with the drive gear and rotates in the opposite direction by a predetermined angle, driving the slide lever in the return direction. A partially toothed gear is provided.

In the disc player with a disc changer according to the present invention configured as described above, when a loading operation is performed to take out a disc selected from a punctured disc and mount the disc in the disc mounting section, first, the disc back is loaded. In order to take out the selected disk, the movable chassis is moved up and down to a predetermined position and then stopped. In this state, for example, the motor is rotated in the forward direction, and upon receiving the rotational driving force in the forward direction of the motor, the drive roller rotates in a direction that moves the disc from the disc back toward the disc mounting section. ,
Also, the arm rotates in the first direction, the driving gear meshes with the partially toothed gear, the rotational driving force of the motor is transmitted to the driving gear, and the partially toothed gear rotates in the positive direction by a predetermined angle and slides. Drive the lever in the disc pull-out direction. As a result, the slide member is driven to pull out the disk selected from the punctured disk, and the pulled-out disk is conveyed toward the disk mounting section by the drive roller.

Furthermore, when an unloading operation is performed to return the disk from the disk loading section to the disk back, the movable chassis is moved up and down to a predetermined position and then stopped in order to return the disk to the disk back. In this state, the motor is rotated in the opposite direction, and receiving the rotational driving force of this motor, the drive roller is rotated in a direction that moves the disc from the disc mounting section toward the disc back, and the arm is rotated in the opposite direction. 2, the driving gear meshes with the partially toothed gear, the rotational driving force of the motor is transmitted to the partially toothed gear via the drive gear, and the partially toothed gear rotates in the opposite direction by a predetermined angle and slides. Drive the lever in the return direction. As a result, the disk removed from the disk mounting portion is inserted into a predetermined storage location for a punctured disk by the driving row.

Since the drive pin 9 is biased in the direction indicated by the arrow a by the spring 12, the drive pin 9 normally assumes a stationary state in which it abuts against the rotation restricting portion 13 provided on the inner wall of the casing 2. As shown in FIG. 2, the bottom plate 2a of the case 2 is provided with a groove 14 extending from the through hole 10 to one end surface and a locking recess 15.

Furthermore, a comb-shaped leaf spring 16 is attached to the disk storage portion 4, which serves to prevent the disk D from undesired movement due to vibrations or the like.

This leaf spring 1G has a number of protruding plate portions 16a corresponding to the number of 50 partition plates, that is, the number of discs D that can be stored, and the bent portion 16b of each protruding plate portion 16a is connected to the disk storage portion 4. Through the notch 17 (Fig. 3) formed in the

are arranged to face each other between the partition plates 5.

At one end of the slider 22, as shown in FIG. A push-out piece 24 is provided that comes into contact with the outer peripheral edge of the slider 22, and a driven piece 26 that protrudes to the outside from a slit 25 (FIG. 2) formed in the presser metal fitting 21 is provided at the other end of the slider 22. It is provided. Note that the slider 22 is moved by driving the driven piece 26.

Based on this configuration, the disk D supported by the partition plate 5 of the disk storage section 4 is not placed in the normal storage position in the disk storage section 4, as shown by the dashed line in FIG. When the disc setting lever 7 is in the position, the driven piece 11 of the disc setting lever 7 is driven to
When the sesoting lever 7 is rotated in the direction shown by the arrow in FIG. 3, the drive pin 9 presses the outer peripheral edge of the disk D, moving from the position shown by the dashed line in FIG. It is moved to the position indicated by . As a result, the disk D is driven and moved to the position shown by the solid line in FIG. 3, and is housed in the normal storage position.

Further, when the slider 22 is moved in the direction of arrow C in FIG. 3 with the disk D placed in the normal storage position, the push-out piece 24 presses the outer peripheral edge of the disk D. At the same time, it is moved from the position shown by the solid line to the position shown by the dashed-dotted line in FIG.

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

That is, as shown in FIG. 1, the disk changer mechanism of this example has a base chassis 27, and this base chassis 27 includes a disk mounting section 28 that is rotationally driven by a spindle motor, and a disk mounting section 28 that is rotationally driven by a spindle motor. An optical pickup 29 is installed to read information signals from the disk D which is attached to the disk drive 28 and rotated.Furthermore, a bank mounting stand 3o is installed, which constitutes a part of the disk changer mechanism and onto which the above-mentioned disk pack 1 is attached. ing. The puncture mounting base 3o has a guide protrusion 31 that engages with a14 (FIG. 2) provided on the bottom of the disc pack 1.
An eject lever 33 with a spring 32 tensioned therein is also provided.

To attach the disk pack 1 to the bank mounting base 3o, insert the $14 of the disk pack 1 into the guide protrusion 3 of the bank mounting base 30.
1 and press the eject lever 3 against the spring 32.
While pressing 3, place the disc pack 1 on the pack mounting base 30.
This is done by sliding it on the top. When the disk pack 1 reaches a predetermined mounting position, a locking member 35 that protrudes from the bottom side to the top side of the bank mounting base 30 through the through hole 34 provided in the pack mounting base 30 locks the disc pack 1. It engages with the recess 15.

As a result, the disk pack 1 is fixed on the computer mounting base 30. At this time, the disk pack l is restricted from moving upward by the presser plate 30a.

Next, a drive mechanism for driving the slider 22 provided on the disk pack 1 in order to take out the disk D from the disk pack 1 fixed on the puncture mounting table 30 in this manner will be described.

As shown in FIGS. 1 and 4, a predetermined one of the sliders 22 disposed on the disk pack 1 is inserted into the opening of the disk pack 1 on a movable chassis 66 that can be raised and lowered by a mechanism to be described later. A slide lever 67 for moving to the third side is attached. This slide lever 67 is provided with a projecting piece 68 for driving the driven piece 26 of the slider 22, and as shown in FIG. 4, the protruding piece 68 drives the slider 22 from the position shown by the solid line to the position shown by the dashed line.As a result, the disk D in the disk pack 1 is driven by the slider 22, and as shown in FIG. As shown by the dashed line, it is moved to the opening 3 side of the disc pack 1.

The slide lever 67 is driven by a mechanism described below. Such a mechanism will be described with reference to FIG. 5. A partially toothed gear 69 in which no teeth are formed is pivotally attached to a rising portion of the movable chassis 66. Partially missing gear 69
A roller 70 is attached to the slide lever 67, and is inserted into a long hole 71 formed in the slide lever 67. A gear 72 is also pivotally attached to the rising portion of the movable chassis 66, and this gear 72 is rotatably supported.

A shaft 74 is fixedly attached to the tip of the arm 73 so as to protrude from both sides of the arm 73, and the portion of the shaft 74 that protrudes from one surface of the arm 73 is connected to the movable chassis 66.
is located in a through hole 75 provided in the rising portion of the
Further, a gear 76 is rotatably attached to a portion protruding from the other surface. This gear 76 is similar to the gear 72
Although not specifically shown here, the arm 73 is in mesh with the small diameter toothed portion 72a of the
is engaged in. Then, the gear 76 and the partially toothless gear 69
It is assumed that the partially toothless gear 69 meshes within the range in which the teeth are formed.

Further, a motor 77 for driving a gear 72 is disposed on the lower surface side of the movable chassis 66.
The driving force of 7 is transmitted to the gear 72 via an intermediate gear group 78. As shown in FIG. 4, the shaft 79 of the gear 72 is integrated with a drive roller 91, which will be described later. Therefore, the motor 77 drives both the slide lever 67 and the drive roller 91.

Based on this configuration, the motor 7 is operated in the state shown in FIG.
7 is started and rotates in the normal direction, and when the gear 72 is rotationally driven in the direction shown by the arrow g, the arm 73, which is engaged with the gear 76 via the friction member, moves while the shaft 74 is restricted by the through hole 75. The gear 72 rotates in the same direction as the rotation direction of the gear 72 until it reaches a position where it tilts downward as shown in FIG.

As a result, the gear 76 meshes with the partially toothless gear 69,
The partially toothless gear 69 rotates in the direction indicated by the arrow in FIG. 5, and then the gear 76 rotates as shown in FIG.
Rotation is stopped when the meshing state with is released.

In this way, by rotating the partially toothless gear 69,
The slide lever 67 is driven by the roller 70 and moves in the direction shown by the arrow i in FIG. 5 (the same direction as the direction shown by the arrow f in FIG. 4), thereby moving the slider 22.

The slide lever 67 is configured to return slightly after the slider 22 is moved to a predetermined position, so that its protruding piece 68 does not come into contact with the driven piece 26 of the slider 22. This is to prevent the driven piece 26 of the slider 22 from interfering with the movement when the slide lever 67 moves up and down.

Next, the motor 77 is reversed, as shown in FIG.
When gear 72 is rotated in the direction indicated by arrow j, arm 73 returns to the position shown in FIG. As a result, the gear 76 meshes with the partially partially omitted gear 69, and the partially partially partially omitted gear 69 rotates in the direction indicated by the arrow in FIG. The meshing condition of is released. As a result, the slide lever 67 returns to its original position and stops.

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. In this way, in this example, the partially toothless gear 6
Since the mechanism uses 9 etc., the slide lever 6
There is no need to separately provide a motor for driving the player 7 and the drive roller 91, and as a result, the overall cost of the player can be reduced, or the player can be made smaller and lighter.

Here, the disk pack 1 is mounted on the bank 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 so as to correspond to the selected disk D. In order to move the entire movable chassis 66 to the position where the slider 22 is disposed, a feed screw member 81 . Drive belt 82. Transmission gear group 84, driven members 84a and 84b, and spring 86
It is made to move by a thread feeding mechanism consisting of etc. Note that the movable chassis 66 has a through hole 66
a and a bearing 111 are formed, and the movable chassis 66
is guided by the guide shaft 110 with the feed screw member 81 inserted into the through hole 66a, and is moved up and down approximately perpendicularly 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 therefore the slide lever 67, moves toward the desired slider 22. be moved to the correct position.

The movable chassis 66 also includes a drive roller 91 for driving the disk D taken out from the disk storage section 4 of the disk pack 1 by the slide lever 67 in a direction along the surface thereof and supplying it to the disk mounting section 28. , driven roller 92. Support plate 93, link member 94. A disk transport means composed of a stopper pin 95, a guide roller 100, etc. is provided, and the movable chassis 66 is further provided with a clamp arm 96. A clamping member 97 having a rotating shaft 96a, an upper flange portion 97a and a lower flange portion 97b. Clamping means consisting of a spring 98 or the like is provided.

In this way, the movable chassis 66 on which the above-mentioned parts and members are installed forms, together with the pack mounting table 30, a disk transport section that constitutes a disk changer mechanism.

Next, in the disc player with a disc changer equipped with a disc changer mechanism to which the disc pack 1 is mounted, according to the present invention configured as described above, selection is made from among the plurality of discs D accommodated in the disc pack 1. The operation from when the disc is loaded into the disc loading section 28 and the information is reproduced until it is returned to the disc pack 1 will be described.

Every time a disk pack 1 containing a plurality of disks D is mounted on the pack mounting base 30, a drive lever and a slider setting lever (not shown) are rotationally driven by a motor, and the disk setting lever is rotated by a motor.
The lever 7 is driven so that each disk D inserted into the disk pack 1 through the opening 3 is stored in the normal storage position in each storage stage, and each slider 22 moves each disk D into the normal storage position. It is aligned in the inoperative position to keep it in the stowed position. Then, when the disc D to be used for information reproduction is specified, the motor 83 rotates, thereby raising or lowering the movable chassis 66, and the slide lever 67 moves the specific slider 22 corresponding to the selected disc D. be moved into position. 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 through the opening 3. It is taken out from disk pack 1.

Then, the removed disk D is connected to the driving roller 91 and t.
It is driven by the uJI roller 92 in a direction along that 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 restrict the disk D from tilting upward.

When the disk D that has been conveyed to the position corresponding to the disk mounting section 28 reaches a position where it comes into contact with the large diameter part of the stopper pin 95, this is detected by an optical sensor (not shown), and the detection result is also The movable chassis 66 is lowered. As a result, the disk D descends 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 disc D is lowered to the position where it is mounted on the disc mounting section 28, the link member 94 connected to the support plate 93
comes into contact with the head of the stopper member 94a, and the disc D is mounted on the disc mounting portion 28. Movable chassis 6 after being
6 is further lowered, the drive roller 9
1. The driven roller 92, guide roller 100, etc. are separated from the disk D mounted on the disk mounting section 28.

At the same time, the other end of the clamp arm 96 contacts the stopper member 102 and rotates, causing the clamp arm 96 to rotate.
7 clamps the disk D to the disk mounting portion 28.

Then, the movable chassis 66 moves to the leaf switch 103 (
By operating FIG. It becomes a state where we can do it.

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. For this reason,
The disk D can rotate without contacting the stopper bin 95.

Thereafter, when the optical pickup 29 finishes reading the information signal from the disk D and the disk D is 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 portion 28, and is again held between the drive roller 91 and the driven roller 92 and raised. When the disk D reaches the position corresponding to the original storage stage within the disk bank 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, thereby returning the slide lever 67 to its original position. At the same time, the disk D is conveyed toward the disk pack 1 by the driving roller 91 and the driven roller 92, and is moved to the position shown by the two-dot chain line in FIG. When the disk D reaches such a position, this is detected by an optical sensor (not shown), and based on the detection result, the rotation of the motor 77 is stopped and the motor is started. As a result, the drive lever and the slider setting lever 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. Slider 2 corresponding to
2 is returned to its original position.

In this way, the loading and unloading operations by the disc changer mechanism are performed.

Effects of the Invention As is clear from the above explanation, according to the disc player with a disc changer according to the present invention, the slide lever and the drive roller provided on the movable chassis that can be moved up and down with respect to the disc mounting section. For example, by rotating a single motor in the forward direction, a slide lever is used to move a slide member provided on the disc puncture, thereby accurately pulling out the selected disc from the disc puncture, and at the same time, the pulled out disc is moved to the drive roller. The slide lever can be quickly and reliably moved toward the disk mounting part by reversing the motor to drive the slide lever and the drive roller, and the slide lever can be returned to its original position. To quickly and reliably return a disc from a disc mounting part to a disc pack. The disc player with a disc changer according to the present invention has a configuration in which both the slide lever and the drive roller are driven by a single motor, and is therefore compared to a disc player in which both the slide lever and the drive roller are driven by separate motors. As a result, the configuration can be simplified, and the cost can be reduced, and further, the size and weight can be reduced.
