Reference numeral 2 denotes a mechanism board, which serves as a base for mounting each mechanical component. Numeral 3 denotes a damper rubber, which is fixed on the mechanism board 2 and is engaged with the traverse mechanism 1 and has a buffering function for preventing shock and vibration from being transmitted to the traverse mechanism. Reference numeral 4 denotes a roller arm, which is disposed on the mechanism substrate 2 so as to be able to move up and down, and moves the disk when the rollers rotate by pressing a pair of rollers 4a and 4b. The roller arm 4 incorporates a member that serves as a guide so that the disk sandwiched between the rollers does not fluctuate up and down even when the disk is in a cantilevered state when the disk is moved horizontally. Reference numeral 5 denotes a magazine in which three CD singles are stored. Disc eject levers 5a, 5b,
5c is arranged, and serves to make the disc harder between the rollers by pushing in the direction of the arrow. The traverse mechanism 1 and the magazine 5 are formed diagonally in a 1DIN size, and the roller arm 4 is disposed obliquely between them. In FIG. 2, reference numeral 6 denotes a first disk,
The magazine 5 is stored in the upper stage, 7 is a second disk, which is stored in the middle stage, and 8 is a third disk, which is stored in the lower stage. Reference numeral 9 denotes a clamper, which is in a relationship of being attracted to the centering ring 1a of the traverse mechanism 1 by a magnet, and performs disk clamping when a disk is mounted. By pressing the disk eject lever 5a of the magazine 5, the disk 6 jumps out of the magazine 5,
It is sandwiched between the passive roller 4a and the driving roller 4b. As the drive roller 4b rotates clockwise, the disk 6 horizontally moves to the right, and the rotation of the drive roller 4b is stopped at a position where it is completely removed from the magazine 5. The roller arm 4 is moved downward with the disk 6 interposed, and the disk 6 is stopped at a position where it can be mounted on the centering ring 1a. Then, the passive roller 4a is released upward, and the drive roller 4b is released downward. By doing so, it is possible to make the music piece playable. In this case, the clamper 9 is located at a position above the disk to be removed from the magazine 5 and, of course, descends in accordance with the downward movement of the disk or after the movement, and the disk is clamped by the traverse mechanism 1 by the clamper 9. After that, the rollers 4a and 4b move in the direction in which they are separated from each other, and of course allow the disk to rotate. With the above configuration,
The magazine 5 can be completely accommodated in the panel within the space of 1 DIN, and the operation required for extracting the disk can be simplified.

Next, FIG. 3 is a plan view showing a configuration in which direct insertion by front loading can be performed in the configuration described in FIGS. 1 and 2, and FIG. 4 is a front panel in that case. Is expressed. In FIG. 3, the roller arm 4 is turned rightward by rotating the roller arm 4 counterclockwise from the state shown in FIG. 1 around the rotation shaft 4c, and reaches a position where it does not contact the magazine 5 even in the height direction.

In order to receive the direction correction by the detection guides 12a and 12b, they are finally stopped at the same position. The roller of the roller arm 4 used in this case has a smaller diameter at the center portion than at both ends, so that the CD single sandwiched between the rollers can easily approach the center. Therefore, since each disc is stopped at a certain position, CD13
There is a part where only one of them is located. By arranging the _three photosensors B ₁ , B ₂ , and B ₃ at the positions shown in consideration of this portion, it is possible to determine whether the disc inserted from the insertion slot is a CD or a CD single. That is, if the photosensor B ₃ at the tip detects a disc, it is determined that the CD single 14 has been inserted at the final position, and only the sensor B ₂ detects the disc,
If the sensors B ₁ and B ₂ have not detected, it is determined that the CD 13 has been inserted at the final position.

Next, FIG. 6 shows the operation in the case of the CD after the discrimination according to FIG. Roller 4 of roller arm 4
By rotating clockwise around the rotating shaft 4c while the CD 13 is still sandwiched between the a and 4b, a state shown by a broken line is obtained.
The guide 12b of the 12 detection guides 12a and 12b is released outward so as not to come into contact with the disc at the position after the rotation.
Next, by rotating the rollers 4a and 4b of the roller arm 4, the disk is moved horizontally again, the rotation is stopped when the playing position is reached, and the clamper 9 is lowered with respect to the traverse mechanism 1 to set the center. The CD 13 can be inserted between the ring 1a and the clamper 9 to be in a mounted state.

Next, FIG. 7 shows the operation in the case of the CD single after the discrimination according to FIG. When the rollers 4a and 4b of the roller arm 4 are rotated clockwise about the rotation shaft 4c while the CD single 14 is sandwiched therebetween, the state shown by a broken line is obtained and this rotation operation is performed. Accordingly, the guide 12b of the 8-12 detection guides 12a and 12b is released outward so as not to come into contact with the disk at the position after the rotation. At this time, the original position of the 8-12 detection guides 12a and 12b is set with respect to the traverse mechanism 1 so that the position after the rotation of the CD single 14 becomes the mounting position. By lowering the clamper 9 with respect to the traverse mechanism 1 after the rotation, the CD single 13 can be inserted by the centering ring 1a and the clamper 9 to be in the mounted state. With the above configuration,
Discrimination of a CD single and mounting operation according to the case of each disc can be performed.

Next, FIGS. 8 and 9 show a configuration for preventing double insertion of a disc during performance or operation, and FIG. 8 shows a state where insertion is possible.

In FIG. 8, reference numeral 15 denotes a blocking lever, which is mounted on the mechanism board 2 so as to be able to move up and down, receives a spring urging force in an upward direction, and is restricted from moving in a lateral direction. When the roller arm 4 is located at a position corresponding to the insertion slot as shown in FIG. 3, the blocking lever 15 is engaged with the roller arm 4 and is stopped at the lowered position against the spring urging force. And therefore direct insertion from the disc 10
If 13 or 14 is inserted, the rollers 4a, 4
It can reach up to b.

Next, in FIG. 9, when the roller arm 4 is at the position shown in FIG.
The engagement relationship with the stop lever 15 is released, and the stop lever 15 is not at the stop position, and is in a state of being lifted upward by a spring urging force. At this time, the blocking lever 15 is
Therefore, even if an attempt is made to insert a disc, the disc cannot be loaded because it is blocked by the blocking lever 15. In the above configuration, the roller arm 4 is in the state shown in FIG. 1 during a performance or a changer operation, and only the state in which direct insertion is possible is shown in FIG. Has become. Therefore, with such a simple configuration, double insertion during performance or changer operation can be prevented.

Next, FIGS. 10 and 11 show a method of loading a disc by the difference between the fixed state of the traverse mechanism and the floating state. FIG. 10 shows the fixed state of the traverse mechanism, and FIG. 11 shows the traverse mechanism. In the floating state. In FIG. 10, reference numeral 16 denotes a fixed lever, which is disposed rotatably from the mechanism board 2 so as to press the traverse mechanism 1 downward.

Is fixed. A spring 18 suspends the traverse mechanism 1 and floats. In the state shown in FIG. 10, the traverse mechanism 1 is pushed down, so that the disk can be moved horizontally and placed on the centering ring 1a of the traverse mechanism 1. Next, as shown in FIG. 11, the traverse mechanism 1 is moved upward by the spring 18 by rotating the fixing lever 16 upward to release the interposition of the fixing pin 1b of the traverse mechanism 1,
In a floating state, it is stabilized at a position balanced by the spring 18. After the traverse mechanism 1 is raised, the disk is mounted by the centering ring 1a and the clamper 9. With the above-described configuration, the disk can be mounted only in the horizontal direction, and the space having the necessary degree of freedom for floating can be effectively used.

Next, FIGS. 12 to 14 show an embodiment of space saving for mounting a disk from a magazine, FIG. 12 shows extraction and horizontal movement of a disk from a magazine, and FIG. FIG. 14 shows the lowering of the disk and the horizontal movement after the lowering, and FIG. 14 shows the positions of the CD, the CD single and the magazine at the disk mounting position. An upper guide pin 19 is arranged to stop the horizontal movement of the CD single taken out of the magazine 5 at a set position. Reference numeral 20 denotes a lower guide pin, which is arranged to stop the CD single at the mounting position, and is configured to escape so as not to come into contact with the CD single in a playing state. In FIG. 12, the disk 6 pulled out of the magazine 5 in the same manner as in the case of FIG.
Is stopped by hitting. The rotation of the roller is stopped by detection by a switch, a photo sensor, or the like, or by time setting. Next, in FIG. 13, the disk 6 sandwiched by the rollers 4a and 4b of the roller arm 4 changes from the position indicated by the broken line to the position indicated by the solid line by the lowering operation of the roller arm 4, and further, the reverse rotation of the driving roller 4b is performed. Moves horizontally in the direction of the arrow, and hits the lower guide pin 20 and stops. As in the case where the drive roller 4b is extracted from the rotating magazine 5, it is detected by a switch or a photo sensor. Next, the solid line 6 in FIG. 14 is the position of the disk 6 (CD single) in the playing state. Also CD
When 13 is inserted through the insertion slot, it will be in the position shown in the figure.
Therefore, it is possible to reduce the space required for mounting and playing the CD 13 as compared with the case of FIG. 2 in which the plane position at the position indicated by the broken line for lowering the disk 6 from the height of the magazine 5 is the mounting position. it can. Disk 6 in the case of FIG.
The outer circumference of CD13 is aligned with the position of the broken line
There is also a lot of space underneath.

In the case of such a configuration, the power supply is cut off or the like.
When performing an initial reset operation when the power is turned on again after the performance is interrupted, the disk 6 shown by the solid line in FIG. 13 is further horizontally moved by the roller arm 4 in the direction of the arrow. The paper is discharged from the direct insertion port 10 shown in the figure. With this control, it is not necessary to discriminate the disc taken out of the magazine 5 and the disc inserted from the direct insertion slot 10 when the power is turned on again, and to simplify the control. Can be.

As described above, according to the present invention, by configuring the disc playing position diagonally with respect to the CD single magazine storage position, the C
When storing a D-single magazine, it has the advantage that the space can be used effectively and the function of the autochanger can be used.

In addition, by providing an insertion slot for loading a CD in the upper or lower part of the magazine storage position, it is possible to directly load a CD with a changer function by the magazine, continuous playback by the magazine and direct insertion without using the magazine Both types of playback are possible and can be used depending on the application.

In addition, since a pair of rollers can be used for both the changer operation and the direct insertion by performing the vertical movement and the rotation operation, the number of parts can be reduced and the number of parts can be reduced as compared with the case where dedicated rollers are arranged. This has the advantage that space can be provided.

In addition, the movement of each of the CD and the CD single at a predetermined position is stopped by a disk guide member provided in front of the roller feed direction, and the difference between the stop positions is detected electrically or mechanically, whereby the type of the disk is determined. This has the advantage that it is possible to easily determine whether or not to shift to the next operation.

Also, by selecting the rotation amount of the roller or the rotation amount of the disk feed or the position of the disk playing positioning guide member interlocked with the rotation member of the roller, depending on the difference in the stop position, the respective disk can be electrically or mechanically selected. Can be moved to the performance position by the respective methods.

Further, by interlocking the disk insertion preventing member with the rotating member of the roller, double insertion of the disk during operation, such as during disk playing or disk removal from the magazine, can be prevented.

At the time of the initial reset operation, the disc is ejected from the direct insertion slot regardless of whether the disc has been ejected from the magazine or inserted from the direct insertion slot. Since it is not necessary to memorize it mechanically or mechanically, there is an advantage that the number of parts can be reduced and initial reset control can be simplified.

In addition, the required space for CD single magazines is reduced by placing the CD single playing position vertically after extracting the disc horizontally from the magazine and then moving it horizontally in the magazine direction. can do.

Also, by fixing the traverse downward during loading, the disk mounting operation can be limited to horizontal movement only, and by releasing the fixation, the traverse can be raised to clamp the disk, and at the same time, it can be freely moved up, down, left and right. It has the advantage of being able to perform stable performance without sound skipping even in the case of car vibration, and to be able to simplify operation and save space. .
