A disc-shaped pressing member 80 is rotatably attached to the surface opposite to the turntable 23 and cooperates with the turntable to perform a disk clamping action. Although not shown, a coil spring is provided that biases the support body 79 in a direction in which the pressing member 80 approaches the disk supporting surface 23a of the turntable 23.

The above-mentioned support body 79, pressing member 80, etc. constitute a clamp mechanism that clamps the disk.

As shown in FIG. 10, a pin 79c extending forward is protruded from the free end of the support body 79, and the pin engages with the planar guide portion 72e at the rear edge of the upper surface of the second lever member 72. It matches. A tapered portion 72f is formed on the left end portion of the second lever member 72 on an extension of the planar guide portion 72e so as to be engageable with a pin 79c of the support body 79. As is particularly clear from FIG. 20, the tapered portion 72f is inclined toward the left (in the direction of arrow X) and upward (in the direction of arrow Z). That is, as the second lever member 72 moves forward (movement to the right = in the opposite direction of arrow The pin 79 is held in the release position and is pushed along the tapered portion 72f.
The pressing member 80 is moved to the clamping position by the lowering of the pressing member 80.

Here, the shapes of the turntable 23 and the pressing member 80 will be described in detail.

As shown in FIG. 23, an annular projection 23c is formed on the outer periphery of the disc-shaped turntable 23 and extends around the entire circumference of the turntable.
It carries 0. On the other hand, an annular projection 80a that contacts the main surface of the disk 10 is also formed on the outer periphery of a disk-shaped pressing member 80, which is a main member of the clamp mechanism and performs a disk clamping action in cooperation with the turntable 23.

A plate-shaped disk holding member 83 is disposed so as to be sandwiched between the movable chassis A19 and a plurality of pins 83a protruding from the disk holding member. It is attached to the movable chassis A by movably engaging the groove 19e. As shown in FIG. 11b, the cam groove 19e is formed to be inclined, for example, toward the left (in the direction of arrow X) and upward (in the direction of arrow Z). That is, the cam groove 19e is formed so that when the disc pressing member 83 moves left and right, the disc pressing member 83 moves up and down. As is clear from FIGS. 9 and 10, a projection 83b extending downward is formed on the lower surface of the right rear end of the disk holding member 83, and one end 70e of the rotating intermediate lever 70 (see FIG. 10) ) pushes the right edge of this protrusion 83b, thereby moving the disk holding member to the left (in the direction of arrow X). Incidentally, the disk holding member 83 is applied with a bias force toward the right (in the direction opposite to the arrow X) by a coil spring 84 shown in FIG. 9, for example.

The above-mentioned disk holding member 83 is connected to the disk-supporting surface of a disk that is moved in a direction (vertical direction) perpendicular to the disk-supporting surface 23a (see FIG. 11b) of the turntable 23 by the disk moving means described above. The lower surface of the disk 1 is brought into contact with the opposing surface of the disk 1, so that the disk 1

FIG. 24 shows a single adapter 90 as a disk holder that is detachable from the magazine mounting portion of the multi-disc player 1 and that accommodates one disk 10 in a replaceable manner. As shown in the figure, the single adapter 90 includes a first member 91 that is directly mounted in the magazine mounting section, and a predetermined range of the first member along the mounting direction of the first member to the magazine mounting section. and a second member 92 that is slidable within and carries a disk. The first member 91 is a bottom plate 93 in the shape of a rectangular plate.
and a top plate 94 having a half-moon-shaped recess 94a formed at its front end. Further, the second member 92 rotates around a sliding plate 95 slidably attached to (the bottom plate 93 of) the first member 91 and a pin 95a protruding from the right rear end of the sliding plate. The tray C96 is movable and supports the disk 10.

As shown in FIG. 25, the bottom plate 93, which is a component of the first member 91, is formed with a pair of rail portions 93a extending in the front-rear direction (the direction of arrow Y and the opposite direction), and a second A plurality of steel balls 95c attached to a projecting portion 95b formed on a sliding plate 95, which is a component of the member 92, smoothly abuts on this rail portion 93a. Note that the bottom plate 93 has a linear opening 9 extending in the front-rear direction in the center thereof.
3c is formed, and a protrusion 95d protruding from the lower surface of the sliding plate 95 slides within the opening, thereby guiding the sliding plate.

A leaf spring 9 made of a steel plate is placed at a position where the above-mentioned overhanging portion 95b and steel ball 95c are sandwiched together with the rail portion 93a.
3d, and is attached to the main body of the bottom plate 93 with screws 93e. This plate spring 93d forms a part of the bottom plate 93. In addition, the bottom plate 9
3 is made of resin except for the leaf spring 93d, and
The sliding plate 95 is made of resin except for the steel balls 95c. That is, the first and second members 91,
One of the sliding contact portions 92 is made of resin, and the other is made of metal.

A coil spring 97 is installed between the front end of the bottom plate 93 and the rear end of the sliding plate 95. This coil spring 97 applies a moving force to the second member 92 including the sliding plate 95. Further, as shown in FIG. 24, a damper 98 having a braking gear 98a is provided at the left end of the bottom plate 93, and a rack portion (not shown) formed on the sliding plate 95 extending in the front-rear direction. This brake gear 9
It meshes with 8a. The damper 98 applies braking force by utilizing the viscosity resistance of a viscous agent such as grease held therein.

As shown in FIG. 24, a pressing lever 101 is provided at the front left end of the sliding plate 95 in the approximately front-back direction (arrow Y
and the opposite direction), and is swingably attached to the sliding plate 95 via a pin 95f at its front end.
However, the pin 95f extends in the vertical direction (arrow Z direction and the opposite direction). Press lever 1
The rear end of the tray C96 can be smoothly engaged with a notch 96a formed in the free end of the tray C96. A spring member 101a is engaged with the pressing lever 101 to apply a tray pressing force to the pressing lever. By these pressing lever 101 and spring member 101a,
A holding mechanism is configured to hold the tray C96 at the storage position within the sliding plate 95.

As shown in FIG. 26, the disks 10
When the second member 91 is moved relative to the first member 91 to place the second member 91, the first member 91 is also made to protrude outside the magazine mounting portion in the housing 2. However, the movement of the second member 92 relative to the first member 91 is performed by a coil spring 97, and the protrusion of the first member 91 from the magazine mounting portion is caused by the swing lever 64 and coil spring 64d shown in FIG. 10, for example. It is done by. In addition, the first
The locking of the member 91 and the second member 92 within the magazine mounting portion is performed by a locking member 67 shown in FIGS. 6 and 19a.

As is clear from FIG. 26, the amount by which the first member 91 is made to protrude from the magazine mounting portion (for example,
50 mm) and the amount of movement of the second member 92 relative to the first member 91 (for example, 75 mm) (125 mm) is slightly larger (5 mm) than the diameter of the disk 10 (120 mm). . With this configuration, the dimensions indicated by U in FIG. 26, that is, the second member 92 (tray C96)
The overlapping dimension of the first member 91 and the second member 92 is relatively large when the second member is projected from the magazine mounting portion in order to attach and detach the disk 10 to and from the magazine.

Note that the storage position of one disk 10 in the single adapter 90 described above corresponds to the position of the approximately central disk among the six disks stored in the magazine 5 (see FIGS. 1 to 5). It is being done as much as possible. As a result, the disk loading state for the single adapter 90 is stabilized, and
The aesthetic appearance of external fitting can be obtained when the first and second members 91 and 92 protrude outside the magazine mounting portion.

Here, the single adapter 90 is inserted into the player main body by the detection switches 34 and 35 shown in FIG. It is also detected that the device is attached. Specifically, an overhang 33g formed on the moving lever 33 for operating the detection switches 34 and 35
A recess is formed in the portion of the single adapter 90 that is to be brought into contact (with which the rear end of the magazine 5 is brought into contact). With this configuration, when the single adapter 90 is attached and when the magazine 5 is attached, the amount of movement of the moving lever 33 changes, and the on/off state of each detection switch 34, 35 changes. It is determined which of the adapter 90 and the magazine 5 is attached.

Although not shown, the single adapter 90 has a second member 92 connected to the first member when the single adapter is not installed in the player body.
A locking mechanism is provided for locking against member 91. The locked state by this locking mechanism is released when the single adapter 90 is installed in the player body.

Next, the operation of the multi-disc player having the above-mentioned configuration will be briefly explained along with the playing procedure with reference to FIGS. 27 and 28.

First, when the disc to be played is designated by operating the operation button group 6 shown in FIG. Alternatively, it starts moving backward (in the opposite direction of arrow Y). Therefore, by the action of the stepped cam grooves 37d, 38d formed in the movable plates 37, 38 and the guide groove 16e formed in the chassis 16, the pin 20c is movably fitted into each groove. Movable chassis B2 that can be moved up and down and has the pin 20c protruding from it.
The moving member 18 including 0 moves up and down. Therefore, the tray protruding member 53 provided on the moving member 18
is the tray 11 carrying the disc to be played.
Alternatively, the engagement position with 12 is reached.

Here, the longitudinal movement and positioning of the movable plate 37 and the vertical movement and positioning of the tray protruding member 53 will be described in detail.

The DCNT signal shown in FIGS. 27 and 28 is a slit detection signal emitted from the photo sensor 51. Further, the DCHM signal is a detection signal emitted from the detection switch 49 that detects that the movable plate 37 is at its most backward movement position (forward movement limit position), that is, the home position.
As shown in FIG. 27, the photo sensor 51
If a movement command is issued while the DCNT signal is being issued, the moving plate 37 is moved by a distance corresponding to the difference between the current address (current DISC) and the desired address (search DISC). Furthermore, if a movement command is received while the photo sensor 51 is not emitting the DCNT signal, the movement plate 37 will be activated by the detection switch 4.
The desired address (search
DISC) position.

When the tray projecting member 53 is thus positioned in the engagement position with the tray carrying the disc to be played, the motor 62 then begins to rotate.
The moving body 56 is driven backward (in the direction opposite to the arrow Y). Therefore, the intermediate lever 70 is rotated counterclockwise in FIG. 10, and the second lever member 72 connected to the intermediate lever is rotated to the right (counterclockwise in FIG.
direction). As shown in Figure 20,
The second lever member 72 is locked with the first lever member 71 by a locking/releasing means comprising a movable piece 76 or the like. Therefore, the first lever member 71 also
It moves to the right together with the lever member 72, thereby rotating the tray protrusion member 53, for example, clockwise in FIG. 10. Therefore, as shown in FIG. 2b, a tray carrying a disk to be played (for example, tray B12) protrudes from the magazine body 8, and the disk is placed on the disk carrying surface 23a of the turntable 23 (see FIG. 11b). The disk is moved to a concentric position with respect to the disk, that is, directly below the disk carrying surface. However, just before the rotation of the tray protruding member 53 and, therefore, the rightward movement of the first lever member 71 is completed, the locking state of the first and second lever members 71 and 72 by the locking/releasing means is changed. After being released, the slight rightward movement of the first lever member 71 is performed by the biasing force of the coil spring 75 (see FIG. 20, etc.), and the arc-shaped portion 12e of the tray B12 pushed by the biasing force (See FIG. 2b) comes into contact with the arc-shaped predetermined contact portion 19c of the movable chassis A19, thereby completing the positioning of the tray. The completion of ejection of the tray from the magazine body 8 is detected by a detection signal from a detection switch 87 (see FIG. 8, etc.) which is activated by the movement of the movable body 56.

The second lever member 72, which has been released from the first lever member 71, is further to the right (counter to the direction of arrow X).
The tapered portion 72f of the second lever member
The support body 79 (shown in FIG. 10) of the clamp mechanism, which is engaged with the pin 79c (shown in FIG. 20), swings upward (in the direction of arrow Z). Therefore, the disk is lifted upward and the turntable 23
clamped against. Note that this upward movement of the disk is shown as DISC/Load in FIG. 27. Further, as the disk moves upward, the disk pressing member 83 also rises together with the disk due to the rotation of the intermediate lever 70.
However, when the loading of the disk onto the turntable is completed, the disk holding member 83 is slightly detached from the disk, and the disk holding member does not interfere with the rotation of the disk.

In this way, it becomes possible to play, and the turntable 23
Then, the carriage 24 (see FIG. 9, etc.) operates to start playing.

When the performance is finished, the disc is stored in the magazine main body 8, but the disc storage operation is performed by following the reverse process of the disc loading operation described above, so a detailed description thereof will not be given. Thereafter, the above operation is repeated according to the specified number of songs.

Incidentally, the ejecting operation of the magazine 5 to the outside of the player body is performed by pressing the button for magazine ejecting among the operation button group 6. When the magazine eject button is pressed, the movable body 56 (for example, see FIG. 19) is moved forward (in the direction of arrow Y) by a predetermined amount, thereby releasing the locked state of the magazine 5 by the locking member 67. be done. As a result, the swing lever 64 shown in FIG. 10 etc. swings about the pin 64a, and the magazine 5 engaged with the free end of the swing lever is pushed out of the player body.

Furthermore, the method of using the single adapter 90 is similar to that of the previous embodiment, except that the magazine 5 and the single adapter are replaced. That is, the single adapter 90 is inserted into the insertion port 3a. At this time,
A locking mechanism (not shown) that locks the second member 92 with respect to the first member 91 is released. At this point, it is pushed in further against the biasing force of the coil spring 97. Then, the first and second members 91,
A locking member 67 engages with a locking recess (not shown) provided in 92 .

Here, when a performance is instructed, the tray C96 is rotated and the performance is performed as in the case of the magazine 5. Here, when the listener wants to change the disk, he or she operates the same magazine eject button as when using the magazine. As a result, tray C96 is rotated in the opposite direction as in the case of magazine 5,
Subsequently, the locking member 67 is disengaged.
Then, the first and second members 91 and 92 protrude until the tray C96 is completely exposed to the outside of the main body, as shown in FIG. The listener now completes the disk exchange by simply replacing the disk on the tray with the desired one and pushing the second member 92 together with the first member 91, so there is no need to remove the single adapter 90 again. . Moreover, by further pulling out the first and second members 91 and 92 in the protruding state, the single adapter 90 can be removed and replaced with the magazine 5.

Effects of the Invention As detailed above, the multi-disc player according to the present invention includes a disc holder, each of which can accommodate at least one disc, and which is removably attached to a predetermined attachment part in the player housing; each includes a disk holder attachment detection means for detecting that the disk holder is attached to the attachment part, and a disk take-out and conveyance mechanism that conveys the disk in the disk holder to a playing position by the playing means, It includes a moving lever that is provided movably along the mounting direction and moves when the disk holder is engaged, and an identification means that detects the amount of movement of the moving lever and identifies the type of the disk holder. Therefore, it is possible to use the single adapter 90, which is a disk holder for one disk and which can accommodate one disk in a replaceable manner and has substantially the same dimensions as a magazine serving as a disk holder for storing a plurality of disks. That is, when the magazine 5 containing a plurality of disks is mounted on the mounting section, the moving lever 33 is moved by, for example, the entire length of its movement stroke, and when the single adapter 90 is mounted, The moving lever is moved by approximately half of the moving stroke, and by detecting the amount of movement of the moving lever, it is detected whether a magazine or a single adapter is attached.

By making it possible to use a single adapter in this way, it is possible to instantly load each desired disc into the player, and
Since disk conversion is also extremely easy, operability is improved.
