DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disc mounting device that automatically mounts a disc on a disc mount part provided to support and rotate the disc in a disc player.

BACKGROUND ART 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 stacked in stages with minute gaps in the vertical direction. The stored disk pack is attached, and the disk changer mechanism mounts a selected one of the plurality of disks stored in the disk pack to the disk mounting portion, that is,
When the loading operation or the operation of removing the disk attached to the disk attachment part from the disk attachment part and storing it in the disk pack, that is, the unloading operation, there is a means for taking out the disk from the disk pack, and a means for attaching the disk to the disk pack. The entire disk transport section of the disk changer mechanism is composed of means for removing the disk from the disk pack, 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 pack. The disc pack can be moved up and down on the side of the opening for inserting or removing the disc, which is provided in the disc pack. 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 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.

Problems to be Solved by the Invention By the way, in the above-mentioned disk player with a disk changer, a selected one of the plurality of disks stored in the disk pack is mounted on the disk mounting part by the disk changer mechanism. In order to achieve the loading operation, the selected disk is securely placed in the disk mounting section even if undesired vibrations or shocks are applied from the outside. A disk transport means that can bring the disk to the corresponding position and a regulating means that controls undesirable behavior caused by disk vibration etc. are required. It is required that it does not become an obstacle to the drive. Furthermore, the disk mounting device including the above-mentioned disk conveying means and regulating means can reduce the price of the disk player, and further,
It is desirable to have a simple configuration in order to reduce the size and weight.

In view of this, the present invention has been developed to ensure that even if undesirable vibrations are applied from the outside during loading operation, the disks will not exhibit undesirable behavior due to vibrations, etc. To provide a disk mounting device which can be mounted on a mounting part, does not interfere with the rotational drive of the disc mounted on the disc mounting part, and has a relatively simple configuration. The purpose is to

Means for Solving the Problems In order to achieve the above-mentioned object, the disk mounting device according to the present invention includes a movable chassis, a drive roller pivoted to the movable chassis, and a movable chassis with the drive roller attached to the disk mounting section. a lifting drive means for raising and lowering the disk, a disk support member connected to the movable chassis via a link member, a driven roller pivotally attached to the disk support member and arranged to sandwich the disk with a drive roller, and a link member. The lifting drive means includes a stopper member provided below, and after the disk is conveyed to a position above the disk mounting part by the rotation of the drive roller while the disk is being held between the drive roller and the driven roller, the movable chassis is moved. The movable chassis is lowered to mount the disk sandwiched between the drive roller and the driven roller on the disk mounting portion, and the movable chassis is then further lowered to separate the drive roller from the disk mounted on the disk mount portion to the lower side thereof. In addition, the driven roller is separated upward from the disk mounted on the disk mounting portion by causing the link member to abut against the stopper member and rotate upward relative to the movable chassis. Ru.

Function In the disk mounting device according to the present invention configured as described above, when a loading operation is performed, the disk selected from the disk pack is
It is pulled out by an appropriate pulling means, inserted between a driving roller and a driven roller, and conveyed toward a disk mounting section while being held between the driving roller and driven roller, so that the disk corresponds to the disk mounting section. When the disc is transported to the position, the movable chassis is lowered by the elevating drive means and the disc is mounted on the disc mounting section. The elevating and lowering drive means further drives the movable chassis to lower the movable chassis even after the disk is mounted on the disk mounting portion. At this time, the link member is brought into contact with the stopper member and rotated upward relative to the movable chassis, thereby separating the disk support member from the movable chassis.
the driven roller is spaced apart above the disk;
Meanwhile, the drive roller is lowered together with the movable chassis and is separated below the disk.

Therefore, according to the disk mounting device according to the present invention, during the loading operation, the disk is prevented from being pinched between the drive roller and the driven roller, causing undesirable behavior due to vibrations, etc. When the disk is mounted on the disk mounting portion and rotated, the driving roller and the driven roller are retracted to a position where they do not interfere with the rotation of the disk.

FIG. 2 is an exploded perspective view showing the entire disk pack, and FIG. 3 is a cross-sectional view thereof.

First, the disk pack 1 mounted on the pack mounting base 30 of the disk player with a disk changer shown in FIG. 1 will be explained with reference to FIGS. 2 and 3. An opening for inserting and removing a disk D is provided on one side of the body 2, and a disk storage portion 4 is provided within the case 2. In the disk storage section 4, a plurality of U-shaped partition plates 5 are arranged in parallel and at the same intervals to form a plurality of storage stages, and the disks D are arranged parallel to each other by the partition plates 5. are supported and stored in a stacked state. The disk storage portion 4 is formed integrally with the case 2 from, for example, a synthetic resin material.

A bearing hole 6 is provided on the outer wall of the disk storage section 4, and a disk setting hole 6 is provided in the outer wall of the disk storage section 4.
The shaft 8 of the lever 7 is fitted. A drive pin is provided at one end of the disk setting lever 7 to move the disk D supported by the partition plate 5 of the disk storage section 4 to the normal storage position in the disk storage section 4 by pressing the outer peripheral edge of the disk D. 9 have been planted. Further, at the other end of the disk setting lever 7, there is a driven piece 1 that protrudes outside through a through hole 10 formed in the bottom plate 2a of the housing 2.
1 is provided. This disk setting lever 7 can be rotated about a shaft 8, but as shown in FIG. 9 assumes a stationary state in which it abuts against a rotation regulating 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-like leaf spring 16 is attached to the disk storage portion 4, which serves to prevent undesired movement of the disk D due to vibrations or the like.
This leaf spring 16 has a number of protruding plate parts 16a corresponding to the number of partition plates 5, that is, the number of disks D that can be stored, and the bent portion 16b of each protruding plate part 16a is a disk storage area. 4 through the notch 17 (FIG. 3) formed in the casing 2, between the partition plates 5 adjacent to each other (in the upper part of the disk storage part 4, between the upper plate of the casing 2 and the partition plate 5 adjacent thereto). Hereinafter, this is also simply referred to as the space between the partition plates 5), and comes into contact with the outer peripheral edge of the disk D in the stored state, thereby preventing undesired movement of the disk D.

Furthermore, as shown in FIGS. 2 and 3, a guide groove 20 is formed on the side surface of the case 2 adjacent to the side surface on which the opening 3 is provided, and a presser foot is positioned in the guide groove 20. A plurality of sliders 22 are arranged, which are held by metal fittings 21 and movable in a direction along the surface of the stored disk D. Each slider 22 is for selectively taking out each disk D stored in the disk storage section 4.
are arranged to face each other between the partition plates 5. At one end of the slider 22, a third
As shown in the figure, from the outer surface of the case 2 to the partition plate 5
An extrusion piece 24 is provided that protrudes between the partition plates 5 through a slit 23 that penetrates between the partition plates 5 and abuts the outer peripheral edge of the disk D stored therein.
A driven piece 26 is provided at the other end of the slider 22 and projects outward from a slit 25 (FIG. 2) formed in the presser metal fitting 21. 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 driven piece 11 of the disc setting lever 7 is driven and the disc setting lever 7 is rotated in the direction shown by the arrow b in FIG. In FIG. 3, while pressing the outer peripheral edge of
It is moved from the position shown by the solid line to the position shown by the dotted chain line. 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 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.

That is, as shown in FIG. 1, the disk chain gear mechanism of this example has a base chassis 27,
The base chassis 27 is provided with a disk mounting section 28 that is rotationally driven by a spindle motor, and an optical pickup 29 that reads information signals from the disk D that is mounted on the disk mounting section 28 and rotated. A pack mounting table 30, which constitutes a part of the disk changer mechanism and on which the above-described disk pack 1 is mounted, is installed. The pack mounting base 30 is provided with a guide protrusion 31 that engages with a groove 14 (FIG. 2) provided on the bottom surface of the disk pack 1, and a spring 3
An eject lever 33 with a tensioned lever 2 is provided.

To attach the disk pack 1 to the pack mounting base 30, insert the groove 14 of the disk pack 1 into the pack mounting base 3.
This is done by sliding the disc pack 1 on the pack mounting base 30 while engaging the guide protrusion 31 of the disc pack 1 and pressing the eject lever 33 against the spring 32. When the disk pack 1 reaches a predetermined mounting position, a locking member 35 protrudes 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.
It engages with the locking recess 15 of the disk pack 1. As a result, the disk pack 1 is fixed on the pack mounting base 30. At this time, the upward movement of the disk pack 1 is restricted by the holding plate 30a.

A selected one of the plurality of disks D stored in the disk pack 1 mounted on the pack mounting base 30 as described above is taken out and mounted on the disk mounting section 28 to perform information reproduction, etc. After that, the series of operations to return to disk pack 1 is as follows.
This is carried out by the members indicated by 66 to 111 in FIG. That is, in order to take out the disk D housed in the disk pack 1, a slider driving means is provided for driving the slider 22 provided on the disk pack 1. It has a lever 67, and 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.
When is moved in the direction indicated by arrow f,
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, disk D in disk pack 1
is pushed by the slider 22 and moved toward the opening 3 of the disk pack 1, as shown by the dashed line in FIG. Note that the slide lever 67 is moved by a roller 70 and a gear 72.
and 76, arm 73, shafts 74 and 79, through hole 7
This is performed by a gear mechanism including a gear mechanism 5, a partially partially partially toothed gear 69, etc., and a motor 77 that drives this gear mechanism. For example, when the motor 77 rotates in the forward direction, the partially partially partially partially toothed gear 69 rotates in the forward direction. When the slide lever 67 is moved in the direction shown by the arrow f in FIG. 4, and the motor 77 is reversely rotated, the partially partially toothed gear 69 is rotated in the opposite direction, and the slide lever 67 is returned to its original position. Been stopping back. Further, the motor 77 remains in operation even after the movement of the slide lever 67 has stopped, and thereafter rotates only the drive roller 91.

In this example, the disk pack 1 is fixedly attached to the base chassis 27, so in order to take out the selected disk D in the disk pack 1, the slide lever 67 must be moved so as to correspond to the selected disk D. Although it is necessary to move the slider 22 to the position where it is disposed, the slide lever 67 is moved by raising and lowering the entire movable chassis 66.

This point will be explained below. As shown in FIG. 7, three feed screw members 81 are rotatably mounted on the base chassis 27. A drive belt 82 is stretched around these feed screw members 81, and the feed screw member 81 adjacent to the motor 83 is connected to the motor 83 via a transmission gear group 84.
It is designed to be rotationally driven by. Based on this configuration, each feed screw member 81 is connected to the motor 8.
3 and rotated at the same time.

Further, as clearly shown in FIG. 5, a pair of driven members 84a and 84b having internal threads are screwed into the feed screw member 81. A screw 85 screwed into the movable chassis 66 is engaged with the driven members 84a and 84b.
The driven members 84a and 84b are movable chassis 6
6, it cannot be rotated. The movable chassis 66 is placed on the driven member 84b with the feed screw member 81 inserted into the through hole 66a provided therein. This movable chassis 66
The diameter of the through hole 66a provided in the feed screw member 81 is set to be sufficiently larger than the diameter of the feed screw member 81. Further, a spring 86 is compressed between the movable chassis 66 and the driven member 84a. With this configuration, even if the parallelism of each feed screw member 81 is not set with high precision, the movement of the movable chassis 66 will not be hindered. That is, the through hole 66a of the movable chassis 66
is sufficiently larger than the diameter of the feed screw member 81, and the movable chassis 66 is connected to the driven member 84a.
and 84b, the movable chassis 66 and the driven members 84a and 84b are relatively movable within a certain range. Therefore, each driven member 84a and 84b can be tilted independently according to the inclination of each feed screw member 81, and even if the parallelism etc. of each feed screw member 81 are not set with high precision, , each driven member 84a and 8
4b can be driven appropriately.
Two guide shafts 110 are implanted in the base chassis 27 so as to be parallel to each other, and two bearings 11 move while being guided by each guide shaft 110.
1 is fixed to the movable chassis 66.

Based on this configuration, when the motor 83 rotates each feed screw member 81, each driven member 84a
and 84b move along each feed screw member 81 with the movable chassis 66, and thereby the slide lever 67 installed on the movable chassis 66 moves.
The slider 22 is moved to the position corresponding to the selected disk D in the disk pack 1. In this case, the position of the movable chassis 66 and therefore the slide lever 67 with respect to each slider 22 is detected by an optical position detection sensor 87 fixed to the movable chassis 66.
7 can be accurately moved to a desired position of the slider 22. In this example, the position detection sensor 87 is adapted to read the slit 89a of the position detection plate 89 installed on the base chassis 27. Alternatively, for example, the slider 22 of the disk pack 1 may be made white and the side surface of the case 2 of the disk pack 1 may be made black.
Each slider 22 itself may be directly detected. In such a case, more accurate position detection can be performed.

The desired slider 2 is moved by the slide lever 67.
2 is driven and the selected disk D is taken out from the disk storage section 4 of the disk pack 1.
As shown in FIG.
are arranged. The driving roller 91 is driven by the motor 77 as described above, while the driven roller 92 is rotatably supported by a support plate 93 as shown in FIG. . The support plate 93 also rotatably supports the guide roller 100 and is connected to the movable chassis 66 via a link member 94. The support plate 93 is urged downward by a spring (not shown), so that the driven roller 92 is pressed against the drive roller 91. moreover,
The base chassis 27 is provided with two stopper members 94a that come into contact with the link member 94 when the movable chassis 66 is lowered to a predetermined position.

With this configuration, when the selected disk D is taken out from inside the disk pack 1 by the slide lever 67 driving the slider 22 and pushed between the driving roller 91 and the driven roller 92, this Disc D is drive roller 9
1 and driven roller 92, and is conveyed to the disk mounting section 28 side.

As shown in FIG. 1, the movable chassis 66 has two stopper pins 95 for restricting further movement of the disk D when the disk D is transported to a position where it can be attached to the disk mounting portion 28. It is provided. This stopper pin 95
consists of a small diameter part and a large diameter part.

A clamp arm 96 is rotatably supported on the movable chassis 66 via a rotating shaft 96a, and a magnetic clamp member 97 for clamping the disk D to the disk mounting portion 28 is provided at one end of the clamp arm 96. It is supported so as to be disposed at an upper position facing the disk mounting section 28. As clearly shown in FIG. 6, the clamp member 97 has an upper flange portion 97a and a lower flange portion 97b. It is arranged on the lower surface side of the chassis 66. Then, the clamp arm 96, which is biased counterclockwise in FIG. 6 by the spring 98, lifts the upper flange portion 97a, so that the clamp member 97 normally moves as shown in FIG.
The lower flange portion 97b is in contact with the lower surface of the movable chassis 66. This results in
The clamp member 97 is designed not to interfere with the movement of the disk D being conveyed to the disk mounting section 28, and furthermore, movement of the clamp member 97 due to external force is prevented. And, as shown in Figure 6,
The lower flange portion 97b of the clamp member 97 includes
An annular rubber member 97c and a magnet 101 are attached, and a clamp arm 96
A stopper member 102 is planted on the base chassis 27 opposite the other end.

With this configuration, when the movable chassis 66 is lowered after the disk D is conveyed by the driving roller 91 and the driven roller 92 to an upper position facing the disk mounting section 28, the position shown in FIG. As shown, the other end of the clamp arm 96 comes into contact with the head of the stopper member 102 and the clamp arm 96 is rotated.
At the same time, the lower flange portion 97b clamps the disk D to the disk mounting portion 28. In this state, the clamp member 97 does not come into contact with either the clamp arm 96 or the movable chassis 66, and can rotate without any trouble while holding the disc D in cooperation with the disc mounting portion 28. In addition, the stopper member 1
02 is said to be able to adjust its height by using screws or the like. By configuring the clamp arm 96 and the clamp member 97 as described above, the disk D can be reliably clamped with a relatively simple configuration, and the overall size can be made relatively small. be able to.

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

Next, according to the present invention configured as above,
In a disk player with a disk changer equipped with a disk changer mechanism to which a disk pack 1 is attached, a selected one of the plurality of disks D accommodated in the disk pack 1 is attached to the disk attachment part 28, and the information is reproduced. The operation from when the data is returned to the disk pack 1 will be described.

Disk pack 1 containing multiple disks D
Each time the disc is mounted on the pack mounting base 30, a drive lever and a disc setting lever (not shown) are rotated by a motor, and thereby,
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 is moved to its respective position. The disk D is aligned in an inoperative position that maintains it 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 66 to
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. Then, 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 driving roller 91 and the driven roller 92 in a direction along its surface, and is moved to a position corresponding to the disk mounting portion 28, as shown in FIG. In this case, the other end of the clamp arm 96 is
It comes into contact with the outer peripheral edge of the disk D and restricts the upward inclination of the disk D.

When the disk D that has been conveyed to the position corresponding to the disk mounting portion 28 reaches a position where it comes into contact with the large diameter portion of the stopper pin 95, this is detected by an optical sensor (not shown), and based on the detection result, the movable chassis 66 is forced to descend. 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 is moved as shown in FIG.
After the movable chassis 66 contacts the head of the stopper member 94a and the disk D is attached to the disk attachment portion 28, the movable chassis 66 is further lowered.
The link member 94 is rotated upward relative to the movable chassis 66, and the support plate 93 is rotated upward relative to the movable chassis 66.
6, and the driven roller 92 and guide roller 100 are separated upward from the disk D mounted on the disk mounting section 28, and as the movable chassis 66 descends, the driving roller 91 moves toward the disk mounting section 28. The disc D is spaced downward from the disc D mounted on the disc D. At the same time, the other end of the clamp arm 96 contacts the stopper member 102 and rotates, and the clamp member 97 moves the disk D to the disk mounting portion 28.
Clamp on. Then, when the movable chassis 66 operates the leaf switch 103 (FIG. 1) to turn it on, the rotation of the motor 83 is stopped, the lowering movement of the movable chassis 66 is stopped, and the disk pickup by the optical pickup 29 is stopped. A state is reached in which the information signal from D can be read. In addition, in this state, the disk D is attached to the stopper pin 9.
The contact state with the large diameter portion of the stopper pin 95 is cut off, and the outer peripheral edge thereof is in a position facing the small diameter portion of the stopper pin 95. Therefore, disk D has stopper pin 9.
It can rotate without touching 5.

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. In this case, data on the position of the original storage stage of the disk D in the disk pack 1 is stored in an electronic control unit (not shown), and the upward movement of the movable chassis 66 is controlled based on this stored data. However, there is a risk that such data may be erased when the power is turned off, for example. Therefore, in this example, if the data on the position of the original storage stage in the disk pack 1 regarding the disk D is erased, it is moved to the opening side of each slider 22 of the disk pack 1. By detecting the position of the disk D, that is, the disk moved toward the opening 3 when the disk D is taken out, data on the position of the original storage stage of the disk D can be obtained. In this example, for example, each slider 22 of the disk pack 1 is made white, the outer surface of the casing 2 of the disk pack 1 is made black, and the optical position detection sensor is installed only on the slider 22 that has been moved toward the opening 3 side. The opening 3 is placed in a position where it can be detected.
The position of the slider 22 moved to the side is detected.

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 such a position, this is detected by an optical sensor (not shown), and the motor is started based on the detection result. 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. The corresponding slider 22 is returned to its original position. And motor 77
rotation is stopped.

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

Effects of the Invention As is clear from the above explanation, according to the disk mounting device of the present invention, during the loading operation, the disk is conveyed while being held between the drive roller and the driven roller provided on the movable chassis. Therefore, even if undesirable vibrations or the like are applied from the outside, undesirable behavior caused by the vibrations of the disk can be restricted and the disk can be reliably transported to the disk mounting section. and,
Next, the disk attachment part of the disk can be attached by lowering the movable chassis, and after the disk is attached to the disk attachment part, the movable chassis is further lowered to move the driving roller and the driven roller to the disk. This allows the disk to be kept in a freely rotating state during playback, etc. Moreover,
The disc mounting device according to the present invention can achieve the above operations with a relatively simple configuration, and contributes to reducing the price of disc players, as well as making them smaller and lighter.
