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

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 convex portion 31 that engages with a groove 14 (FIG. 2) provided on the bottom surface of the disk pack 1, and also has 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 accommodated 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, and information reproduction, etc. is performed. After that, a series of operations for returning the disk pack 1 to the disk pack 1 is performed by each member shown at 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 for driving the slider 22 provided on the disk pack 1 is provided, and this slider driving means is driven by a slide lever attached to the movable chassis 66. 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. 4, when the slide lever 67 is moved in the direction indicated by the arrow f, the protruding piece 68 drives the slider 22 from the position indicated by the solid line to the position indicated by the dashed line. As a result, disk D in disk pack 1 is moved to slider 22.
4, and is 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 the roller 70, the gears 72 and 76, and the arm 7.
3. A gear mechanism consisting of shafts 74 and 79, a through hole 75, a partially toothed gear 69, etc., and a motor 77 that drives this gear mechanism. For example, when the motor 77 is rotated forward, the partially toothed gear gear 69
rotates in the forward direction to move the slide lever 67 in the direction shown by arrow f in FIG. 67 returns to its original position and stops. 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.

Here, the disk pack 1 is mounted on a pack mounting base 30 installed on the base chassis 27, and in order to take out the selected disk D in the disk pack 1, a slide lever 6 is pressed.
7 to the position where the slider 22 corresponding to the selected disk D is located, this movement of the slide lever 67 is performed by raising and lowering the entire movable chassis 66. .

This point will be explained below. As shown in FIG. 1, 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, they are 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 such a configuration, even if the parallelism of each feed screw member 81 is not set with high precision, there will be no problem in the movement of the movable chassis 66. 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 along with the movable chassis 66, whereby 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, an optical position detection sensor 87 fixed to the movable chassis 66 detects the position by reading the slit 89a of the position detection plate 89, and moves based on the detection signal obtained from the position detection sensor 87. The chassis 66, and therefore the slide lever 67, can be accurately moved to the desired position of the slider 22.

The movable chassis 66 also includes a drive roller 91, a driven roller 92, a support plate 93, a link member 94, and a stopper pin 95 in order to supply the disk D taken out from the disk storage section 4 of the disk pack 1 to the disk mounting section 28. The movable chassis 66 further includes a clamp member 97 having a clamp arm 96, its rotating shaft 96a, an upper flange portion 97a, and a lower flange portion 97b. , a spring 98, and the like. 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 a disc pack is mounted on the pack mounting base 30, a drive lever and a slider setting lever (not shown) are rotated by a motor, and thereby the disc setting lever 7 is driven and the disc pack 1 is placed on the disc pack 1. Each disk D inserted through the opening 3 is stored in a normal storage position in each storage stage, and each slider 22 is aligned in a non-operating position to keep each disk D in the normal storage position. . When the disk D to be used for information reproduction is designated, the motor 83 rotates, thereby raising or lowering the movable chassis 66 as described above, and the slide lever 67 is moved to the selected disk D.
The slider 22 is moved to a specific position corresponding to the slider 22. 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 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 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 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. 1) to turn on the motor 83.
The rotation of the movable chassis 66 is stopped, and the lowering operation of the movable chassis 66 is stopped, so that 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 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, in the disk player with a disk changer according to the present invention, the detection means of the position detection sensor is mounted on the opening side of the disk pack along with the movable chassis provided with the disk transport means. The disk pack is moved along the stacking direction of the disks and placed on the base chassis or disk pack on which the pack mounting section is installed, so as to correspond to the storage position of each disk stored in the disk pack attached to the pack mounting section. A position detection index is detected, and based on a detection signal obtained from the position detection sensor, the driving means determines the position the movable chassis should take when taking out the disk from the disk pack or the position it should take when returning the disk to the disk pack. Since the movable chassis is configured to be moved to a certain position and stopped, the stopping position of the movable chassis relative to the disk pack can be accurately detected with a simple configuration, and the loading or unloading operation by the disk changer mechanism can be performed quickly and reliably. In addition, it is possible to reduce the cost, and furthermore, to reduce the size and weight.
