B. Summary of the invention The present invention is designed to hold a disk in a predetermined storage position, and is equipped with a disk magazine that is provided with an opening for inserting and removing the disk. In a disk player that is supposed to be pulled out from the storage position and stored in the storage position in the disk magazine, a device is placed on the opening side of the installed disk magazine to move the disk from outside the disk magazine into the inside of the disk magazine. The disk, which is partially protruded outside the opening of the loaded disk magazine and is partially housed in the disk magazine, is transferred to the opening of the loaded disk magazine by the disk transfer means. By pushing the disk magazine into a predetermined storage position within the disk magazine by means of a disk pushing means arranged outside the disk magazine and moving linearly in a direction passing through the opening, The disk can be reliably stored in the storage position in the disk magazine using a movable means that requires a relatively small space.

C. Prior Art A disk magazine that accommodates a plurality of disks is installed, and a selected disk is pulled out from the disk magazine and installed in the disk mounting section to reproduce or record information. A disk player has been proposed that is equipped with a disk attachment/detachment mechanism that detaches a disk attached to a disk attachment section from the disk attachment section and stores it in a disk magazine again.

Such a disk player supports a plurality of disks in the mounted disk magazine so that, for example, a plurality of disks are stacked parallel to each other and at predetermined intervals in the vertical direction. In addition, the operation of attaching a selected one of the plurality of disks stored in the disk magazine to the disk mounting section by the disk attachment/detachment mechanism, that is, the disk closing operation, or the detachment of the disk from the disk mounting section. When the operation of storing the disk in the disk magazine, that is, the disk unrotting operation, is performed, there is a means for taking out the disk from the disk magazine, a means for attaching and detaching the disk to and from the disk mounting section, and a means for attaching the disk to the disk magazine and the disk mounting section. A disk transport unit, which includes a disk transfer means and the like, moves up and down with respect to the mounted disk magazine on the side of the opening for inserting and removing the disks it has. This kind of vertical movement of the disk transport unit is
To search for a storage stage in order to take out a selected disk from among a plurality of disks stored in stages in a disk magazine, and to attach a disk to a disk mounting section and to detach the disk from the disk mounting section. , and is further performed to search for a storage stage of the disk magazine into which the disk that has been removed from the disk mounting section should be returned.

Further, the disk transfer means constituting the disk transfer section is, for example, disposed on the opening side of the loaded disk magazine and engages with a disk that partially or completely appears outside the disk magazine. , is a roller device that conveys the disk in a direction along its surface. The roller device pulls out the disk from the disk magazine through the opening during the disk loading operation, and inserts the disk into the disk magazine through the opening during the disk unloading operation.

D Problems to be solved by the invention By the way, as mentioned above, the disk transport section
When a mounted disk magazine is moved up and down on its opening side, the disks stored in the disk magazine are incompletely stored and are not placed in the correct storage position in each storage stage. When a part of the disk protrudes from the opening of the disk magazine, the portion of the disk transport unit that moves up and down that faces the opening collides with or contacts the disk that protrudes from the opening. In addition to being damaged, there is a risk that disk loading or unloading operations may be hindered.

Particularly, in the disk unloading operation, when the disk is inserted into the disk magazine through its opening and returned to a predetermined storage stage in the disk magazine by the roller device forming the disk transfer means as described above, the disk If the storage is incomplete and a portion of the disk protrudes from the opening of the disk magazine, the above-mentioned inconvenience is likely to occur when a subsequent disk loading operation is performed.

In view of this, the present invention is designed to hold the disk in a predetermined storage position, and a disk magazine is installed, which is provided with an opening for inserting and removing the disk, and the disk is inserted into the disk magazine. It is assumed that the disk is pulled out from the storage position and stored in the storage position in the disk magazine, and when the disk is inserted from the opening of the installed disk magazine and stored in the specified storage position, The storage of the disk in the storage position is also carried out reliably without causing a situation where the disk is left in an incomplete storage condition, using a movable means that requires a relatively small installation space. The purpose is to provide a disc player with

In the disk magazine 20, the slider 27 is turned on by engaging with the protrusion 38 of the slider 27 corresponding to the uppermost disk storage stage that assumes the disk push-out position, whereby the detection output signal Sa is output from the detection switch 132. Control unit 13
4.

Then, in the control unit 134, based on the detection output pulse signal Sb from the photo sensor 130, the movable chassis 50
It is detected that the disk D, which has been removed from the disk D, has been moved to a position in the disk magazine 20 that corresponds to the uppermost disk storage stage, which is the previously stored disk storage stage to be stored. By or,
By supplying the detection output signal Sa from the detection switch 132 to the control unit 134, the sending of the drive control signal Qa from the control unit 134 is stopped, and the operation of the motor 44 is stopped. As a result, the movable chassis 50 is moved to a position where the disk D detached from the disk mounting portion 14 is placed at a position corresponding to the uppermost disk storage stage, which is the disk storage stage to be stored in the disk magazine 20. forced to stop.

Next, a drive control signal is sent from the control unit 134.
Qb is sent out, the motor 65 is operated, the drive roller 71 is driven, and the disk D held between the drive roller 71 and the flexible roller 72 is guided by the flexible roller 72 and the guide roller 76. From the position shown by the solid line in FIGS. 6 and 8, a state is taken in which the disk is transferred to be inserted into the uppermost disk storage stage in the disk magazine 20. At this time, as the disk D is transferred, detection output signals Sc and Sd are obtained from the position sensors 80 and 82 and supplied to the control unit 134, and the detection output signals Sc and Sd from the position sensors 80 and 82 are When the disk D passes through the position shown by the one-dot chain line in FIG. When the operation is stopped, a portion of the disk D protrudes outside from the opening 21 of the disk magazine 20, as shown by the two-dot chain line in FIG. 6 and the one-dot chain line in FIG. It is assumed to take a position.

When such a state occurs, a drive control signal Qc is sent from the control unit 134 in response to the detection output signal Sd from the position sensor 82, and the motor 125 is activated. This operation of motor 125 causes gear 118 to rotate in the direction shown by arrow A in FIG. 5 via gear 126 and worm gear 122, and gear 93 to rotate in the direction shown by arrow B in FIG. Rotate in the direction shown. While this gear 93 is rotated once, the cutout flange portion 93a provided thereon turns the switch 128 from the OFF state to the ON state, and then to the OFF state again, and at this time, the signal Se obtained from the switch 128 is transmitted to the control unit. 134 and thereby gear 93
When the switch 128 is turned from the on state to the off state by one revolution, the control unit 13
4 is stopped, and the operation of the motor 125 is stopped. That is, gear 93
is rotated by one rotation.

By one rotation of the gear 93, the setting lever 90 is reciprocated from the position shown by the solid line in FIG. The engaged piece 96 is attached to the slider 2 corresponding to the uppermost disk storage stage of the disk magazine 20.
7 is moved from the position shown by the one-dot chain line to the position shown by the two-dot chain line. As a result, the slider 27 corresponding to the uppermost disk storage stage of the disk magazine 20 is returned to the non-operating position.

At the same time, one rotation of the gear 93 moves the movable lever 104 about the shaft 102 from the position shown by the solid line in FIG. 5 to the position shown by the dashed line, and then returns to the position shown by the solid line again. It is forced to rotate back and forth. As a result, the plate-shaped portion 86c of the disk pushing member 86 engaged with the movable lever 104 reaches the position shown by the dashed-dotted line from the position shown by the solid line in FIG. 5 under the guidance of the guide shaft 100. After that, it is moved back and forth again to return to the position indicated by the solid line.

As a result, the disk abutting portion 86b of the disk pushing member 86 moves from the position corresponding to the end of the opening 21 of the disk magazine 20, which is shown by a solid line in FIG. 6 and a dashed line in FIG. The upper fixed shear is moved so that it reaches a position corresponding to the center of the opening 21 of the disk magazine 20 shown by a solid line in FIG. 42
It is caused to reciprocate linearly in a direction passing through the opening 21 along a long hole 42a provided in the opening 21. Then, a disk pushing member 86 that performs such reciprocating movement
During its forward movement, that is, the disk contact portion 86b of
During the transition from the position corresponding to the end of the opening 21 of the disk magazine 20 to the position corresponding to the center of the opening 21 of the disk magazine 20, the position shown by the two-dot chain line in FIG. 6 and in FIG. A part of it is the opening 21 of the disk magazine 20, as shown by the dashed line.
The disk D is moved while being in contact with the edge of the disk D, which is supposed to protrude outward from the disk, and the disk D is pushed into the uppermost disk storage stage of the disk magazine 20, as shown by the broken line in FIG. It is assumed that the disc magazine 20 is housed in the disc magazine 20 as shown in FIG.

In this way, the disk D is detached from the disk mounting section 14 and the magazine mounting section 1
After the disk magazine 20 is stored in the disk storage stage to be stored in the disk magazine 20 attached to the disk magazine 6, the locking means for restraining the disk magazine 20 to the magazine mounting section 16 is released, and the disk magazine 20 is detached from the magazine mounting section 16. be done.

H. Effect of the invention As is clear from the above explanation, in the disc player according to the invention, when a disc is inserted through the opening of the disc magazine mounted in the magazine mounting part and stored in a predetermined storage position, Even when storing the disc in the storage position, it is first inserted into the mounted disk magazine through its opening, and then a part of it protrudes outside the opening and assumes a position where it is partially stored in the disk magazine. The disk is pushed into a predetermined storage position in the disk magazine by a disk pushing means placed outside the opening of the loaded disk magazine, ensuring that the disk is in the normal storage state. shall be placed in Furthermore, since the disk pushing means is configured to move linearly in a direction passing through the opening of the loaded disk magazine, the installation space thereof can be relatively small.

Therefore, a means for reliably storing a disk in the correct storage position of the disk magazine in which it is attached can be obtained in a relatively small space, and the overall size and simplicity can be achieved. It will be done.

Furthermore, according to the disk player of the present invention, no burden is imposed on the disk magazine side in reliably storing the disk in the correct storage position of the attached disk magazine, so that the disk magazine can be simplified. There are no restrictions on miniaturization, weight reduction, etc.
