Next, a description will be given of a drive mechanism for driving the slider 22 provided on the disk pack 1 so as to send out the disk D from the disk pack 1 fixed on the pack mounting table 30 in this manner.

As shown in FIGS. 1 and 4, the disk is moved up and down by a mechanism to be described later with respect to the disk pack 1 mounted on the pack mounting table 30 along the stage mounting direction of the plurality of disks D. The movable chassis 66 is provided with the slider 22
And a slide lever 67 for moving a predetermined one of the disk packs 1 toward the opening 3 of the disk pack 1 is disposed behind the pack mounting table 30 in the mounting direction of the disk pack 1 as indicated by an arrow X. It is provided. The slide lever 67 is connected to the opening 3 of the disc pack 1 mounted on the pack mounting table 30.
Are provided so as to face the side surface adjacent to the side surface provided with, and move substantially in parallel with the side surface adjacent to the side surface provided with the opening 3 in the disk pack 1.

The slider 22 has a slider 22.
A protrusion 68 for driving the driven piece 26 is provided, and as shown in FIG. 4, when the slide lever 67 is moved in the direction indicated by the arrow f, the protrusion 68 causes the slider 22 to move. Drive is performed from the position indicated by the solid line to the position indicated by the dashed line. As a result, the disk D in the disk pack 1 is driven by the slider 22 and moved to the opening 3 side of the disk pack 1 as shown by a dashed line in FIG.

The slide lever 67 is moved substantially in parallel with a side surface adjacent to the side surface on which the opening 3 is provided in the disk pack 1 mounted on the pack mounting base 30 by a mechanism described below.

Such a mechanism will be described with reference to FIG.
A partially missing gear 69, part of which has no teeth, is axially mounted on a rising portion of the movable chassis 66. A roller 70 is attached to the partially toothless gear 69 and is inserted into an elongated hole 71 formed in the slide lever 67. A gear 72 is also axially mounted on the rising portion of the movable chassis 66, and an arm 73 is rotatably supported by the gear 72. A shaft 74 is fixed to the distal end of the arm 73 so as to protrude from both surfaces of the arm 73. A portion of the shaft 74 protruding from one surface of the arm 73 is provided at a rising portion of the movable chassis 66. Is located in the through hole 75, and the portion protruding from the other surface includes:
A gear 76 is rotatably mounted. This gear 7
Reference numeral 6 meshes with a small-diameter tooth portion 72a of the gear 72, and is engaged with the arm 73 via a friction member, though not specifically shown here. The gear 76 and the partially missing gear 69 mesh with each other in a range where the teeth of the partially missing gear 69 are formed.

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

Under such a configuration, when the motor 77 is started and rotates forward in the state shown in FIG. 5 to rotate the gear 72 in the direction shown by the arrow g, the gear 76 is connected to the gear 76 via a friction member. The engaged arm 73 rotates in the same direction as the rotation direction of the gear 72 until the shaft 74 is in a state where the movement of the shaft 74 is restricted by the through hole 75, and tilts downward as shown in FIG. As a result, the gear 76 meshes with the partially missing gear 69, and the partially missing gear 69 rotates in the direction indicated by the arrow h in FIG. 5, and then engages with the gear 76 as shown in FIG. Is released, the rotation is stopped in a state of rotating by a predetermined angle. As described above, when the partially toothless gear 69 rotates by a predetermined angle, the slide lever 67 is driven by the roller 70, and the slide lever 67 is moved to the position indicated by the one-dot chain line in FIG. Until it reaches the position indicated by reference numeral 70 ', the slider 22 is moved in the direction indicated by arrow i in FIG. 5 (the same direction as the direction indicated by arrow f in FIG. 4) to move the slider 22 to a predetermined position. And, as a result, assume the position shown by the dashed line in FIG. Further, due to the additional rotation of the partially-toothed gear 69 in the direction indicated by the arrow h in FIG. 5 after that, the slide lever 67 moves the roller 70 to the position indicated by the dashed line in FIG. 5) to the lower side of FIG.
At a position slightly opposite to the direction indicated by the arrow i. As a result, the position is indicated by a solid line in FIG. Avoid contact. This is to prevent the driven piece 26 and the like of the slider 22 in the disk pack 1 from hindering the movement of the slide lever 67 that moves up and down as the movable chassis 66 moves up and down.

When the motor 77 rotates in the reverse direction and rotates the gear 72 in the direction indicated by the arrow j as shown in FIG. 6, the arm 73 returns to the position as shown in FIG. Thereby, the gear 76 meshes with the partially missing gear 69, and the partially missing gear 69 rotates in the direction indicated by the arrow k in FIG. 6, and then engages with the gear 76 as shown in FIG. Is released, and as a result, the slide lever 67 returns to its original position and stops.

The motor 77 remains in operation even after the movement of the slide lever 67 stops, and thereafter, only the drive roller 91 is driven to rotate. As described above, in this example, since the mechanism using the partially missing gear 69 and the like is used, it is not necessary to separately provide a motor for driving the slide lever 67 and the drive roller 91. Cost, or miniaturization and weight reduction.

Here, the disk pack 1 is mounted on the pack mounting table 30 of the disk changer mechanism, and the slide lever 67 is moved to the selected disk D in order to send out the selected disk D in the disk pack 1. In order to move the movable chassis 66 to a position where the slider 22 corresponding to the feed screw member 81, the drive screw member 81, the drive belt 82,
A plurality of disks D are moved up and down by a screw feed mechanism including a transmission gear group 84, driven members 84a and 84b, a spring 86, and the like, with respect to the disk pack 1 mounted on the pack mounting table 30. The movement along the loading direction is performed. The movable chassis 66
Are formed with a through hole 66a and a bearing 111. The movable chassis 66 is guided by the guide shaft 110 in a state where the feed screw member 81 is inserted through the through hole 66a, and is substantially perpendicular to the disk mounting portion 28. It is moved up and down in the direction. In this case, the position detection is performed by the optical position detection sensor 87 fixed to the movable chassis 66 reading the slit 89a of the position detection plate 89, and based on the detection signal obtained from the position detection sensor 87, the movable chassis 66, Therefore, the slide lever 67 is accurately moved to the desired position of the slider 22.

In the movable chassis 66, the disk D sent from the disk storage section 4 of the disk pack 1 by the slide lever 67 is driven in a direction along its surface and supplied to the disk mounting section 28. Drive roller 9
1, a disk transport means including a driven roller 92, a support plate 93, a link member 94, a stopper pin 95, a guide roller 100, and the like is provided.
The driven roller 92 is disposed between the opening 3 of the disk pack 1 mounted on the pack mounting table 30 and the disk mounting section 28 facing the opening 3. Further, the movable chassis 66 is provided with a clamp means including a clamp arm 96, a rotation shaft 96a thereof, a clamp member 97 having an upper flange portion 97a and a lower flange portion 97b, a spring 98 and the like.

In this manner, the movable chassis 66 on which the above-described components and members are installed forms a disk transport unit that constitutes a disk changer mechanism together with the pack mounting table 30. , The driving lever 91 and the driven roller 92 respectively constitute loading means, and a loading portion is formed by them.

Next, in the disk player with the disk changer having the disk changer mechanism for mounting the disk pack 1 according to the present invention configured as described above, of the plurality of disks D accommodated in the disk pack 1, The operation performed after the selected item is mounted on the disk mounting unit 28 and the information is reproduced and returned to the disk pack 1 again will be described.

Each time the disk pack 1 containing a plurality of disks D is mounted on the pack mounting table 30, a drive lever and a slider setting lever (not shown) are driven to rotate by a motor. 7 is driven and the disk pack 1
Each disk D inserted from the opening 3 is stored in a normal storage position in each storage stage, and each slider 22 is aligned with a non-operation position for keeping each disk D in a normal storage position. I'm sullen. When the disk D to be used for information reproduction is designated, the motor 83
Is rotated, whereby the movable chassis 66 is raised or lowered, and the slide lever 67 is moved to the position of the specific slider 22 corresponding to the selected disk D.

Then, in this state, the motor 77 starts to rotate forward, the slide lever 67 is moved, and the slider 22 corresponding to the selected disk D is moved from the non-operation position to be selected. The disc D is sent from the disc pack 1 through the opening 3. Then, the sent disk D is driven by the driving roller 91.
And the driven roller 92 is driven in a direction along the surface thereof, and is moved to a position corresponding to the disk mounting portion 28. In this case, the other end of the clamp arm 96 comes into contact with the outer peripheral edge of the disk D, thereby restricting the upward inclination of the disk D.

When the disk D transported from the disk pack 1 mounted on the pack mounting base 30 to a 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 not shown. The movable chassis 66 is detected by the optical sensor and lowered based on the detection result. As a result, the disk D descends toward the disk mounting portion 28, and the disk mounting portion 2
8 is attached. Thereafter, the movable chassis 66 is further lowered.

When the disk D is lowered to the position where the disk D is mounted on the disk mounting portion 28, the link member 94 connected to the support plate 93 contacts the head of the stopper member 94a, and the disk D is placed on the disk mounting portion 28. After the movable chassis 66 is further lowered after being mounted,
Drive roller 91, driven roller 92, and guide roller 10
0 is separated from the disk D mounted on the disk mounting unit 28. At the same time, the clamp arm 96 rotates with its other end abutting on the stopper member 102, and the clamp member 97 clamps the disk D to the disk mounting portion 28.

When the movable chassis 66 operates the leaf switch 103 to turn it on,
The rotation of the motor 83 is stopped and the lowering movement of the movable chassis 66 is stopped. Thereafter, as shown in FIG. 1, the movable chassis 66 is moved along the longitudinal direction of the opening 28B, thereby being mounted on the disk mounting portion 28. The optical pickup 29 is moved along the radial direction of the disc D, so that an information signal can be read from the disc D. At this time, the moving direction of the optical pickup 29 along the radial direction of the disk D is determined by the driving rollers 91 and
The transport direction of the disk D transported from the disk pack 1 mounted on the pack mounting table 30 to the disk mounting section 28, which is determined by the driven roller 92 and the guide roller 100, etc., and accordingly, the disk mounted on the pack mounting table 30
Center of disk D stored in pack 1 and disk
A place preset with respect to a line connecting the center of the mounting portion 28
A predetermined angle of about 45 degrees is formed with respect to a direction forming a predetermined angle. The result
As a result, the moving distance of the optical pickup 29 along the direction in which the disk D is transported to the disk mounting section 28 and the moving distance of the optical pickup 29 along the direction orthogonal to the direction of transport of the disk D to the disk mounting section 28 are described. Each of them is smaller than the moving distance of the optical pickup 29 in the radial direction of the disk D. In this state, the disk D stops the contact state with the large-diameter portion of the stopper pin 95, and the outer peripheral edge thereof is located at a position facing the small-diameter portion of the stopper pin 95. Therefore, the disc D can rotate without contacting the stopper pin 95.

After that, the reading of the information signal from the disk D by the optical pickup 29 is completed.
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 sandwiched between the driving roller 91 and the driven roller 92 to be raised. Then, when the disk D reaches the position corresponding to the original storage stage in the disk pack 1,
The movement of the movable chassis 66 is stopped.

When the disk D is moved to a position corresponding to the original storage stage in the disk pack 1, the motor 77 rotates in the opposite direction to the above case, whereby the slide lever 67 is moved back to the original position. At the same time, the disk D is conveyed to 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 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, as shown by the solid line in FIG. 4, the disk D is returned to the original storage position in the original storage stage.
Is returned to the original position. Then, the rotation of the motor 77 is stopped.

Thus, the loading operation and the unloading operation by the disk loading section of the disk changer mechanism are performed.

Is assumed to move up and down with respect to the pack mounting portion, and the pack mounting portion is fixed, and the disk pack with respect to such a pack mounting portion has a side surface adjacent to the side surface provided with the opening. Since it is mounted from the side of the pack mounting part along the mounting direction that is the front end face, the height dimension governed by the pack mounting part or the disk pack mounted on it is as small as possible. Is done.
In order to read information signals from the disk mounted on the disk mounting portion by the loading device, the disk is transferred from the disk pack mounted on the pack mounting portion to the disk mounting portion, and is read from the disk mounted on the disk mounting portion. An information reading unit, which is arranged to move in the radial direction of the disk while facing the disk, moves the disk in the radial direction by moving the center of the disk contained in the disk pack mounted in the pack mounting unit and the disk mounting unit. and the center of the direction forming an angle of a preset substantially 45 degrees with respect to the line connecting the, i.e., with respect to the transport direction to the disk mounting portion of the disc sent from the disk pack defined by the loading device unit, pre The movement is performed by moving along a direction that forms an angle of approximately 45 degrees .

Thus, the moving distance of the information reading unit along the direction in which the disk is transported to the disk mounting unit and the moving distance of the information reading unit along the direction orthogonal to the direction in which the disk is transported to the disk mounting unit. Each of them is smaller than the moving distance of the information reading unit in the radial direction of the disk, and therefore, a space for moving the information reading unit in the radial direction of the disk mounted on the disk mounting unit is secured. The information reading unit is smoothly moved in the radial direction of the disk mounted on the disk mounting unit, and the pack mounting unit, the loading device unit, the disk mounting unit, and the information reading unit are arranged in such a state. Size of the entire part including the disc in the transport direction of the disc toward the disc mounting section, and furthermore, the transport of the disc toward the disc mounting section. Dimension in the direction perpendicular to the direction will be small as much as possible.
