Description

TECHNICAL FIELD The present invention relates to a disc player, and more particularly to a multi-disc player that can accommodate a plurality of discs and can sequentially select any of the stored discs for continuous play.

A jukebox is generally known as a disc player that operates on a 1"1 system. However, conventional jukeboxes have very large bodies, making them unsuitable for home use.

In recent years, it has been called a digital A-disc (hereinafter abbreviated as DAD), and by recording digital signals, it is possible to increase the amount of information that can be stored compared to conventional audio discs that record analog signals. Several types of discs that also generate less noise during playback have been developed and are now in widespread use.

Among these, disks with an outer diameter of about 12 CTl, which are generally called compact disks and which record and read signals using laser light, are easy to handle and allow the overall size of the disk player to be made smaller. It is. Recently, a multi-disc player A7 has been developed that can store multiple small DADs (for example, 5 to 6 discs) at all times and is ideal for use as a home jukebox that plays them continuously.
is being developed. By the way, the playing time of a small DAD is 1 hour, which is about 1 hour longer than a conventional analog audio disc.
It can accommodate 5 times more information. Therefore, for example, six discs can store approximately 120 songs with a performance time of around 3 minutes, and it is also easy to organize them by genre of your choice, such as jazz or enka.

A multi-disc player basically consists of a performance means including a turntable, a pickup, etc., a magazine that stores a plurality of discs arranged in a predetermined format, and sequentially selects any discs to be inserted into the magazine. The disc is also provided with a performance position, that is, a disc ejecting and transporting machine that transports the disc onto the turntable. Additionally, a locking mechanism is provided to lock the magazine in the installed position with respect to the player housing.In already developed multi-disc players, the locked state of the magazine by the locking mechanism is determined in response to a magazine eject signal. A lock release means such as an electromagnetic solenoid is installed to release the lock)
This was an issue that needed to be solved in order to reduce the size and cost of the player.

The present invention has been made in view of the above points, and its object is to provide a special means for releasing the locking mechanism that locks the machine to the player housing. It is an object of the present invention to provide a multi-disc player which can reduce the size of the player and reduce the cost.

The multi-disc play V according to the present invention moves a predetermined moving body to transport the disc to be played in a direction perpendicular to the disc carrying surface of the turntable.
It is characterized in that the magazine is unlocked from the player housing.

The above-mentioned lock/release means (comprised of rotatable 76, etc.) include first and second lever parts 71, 72, a coil spring 75 as a biasing means, a movable body 56, a motor 62, etc. 2. Drive mechanism that drives the lever member 72 (described above)
This constitutes a tray protrusion member driving means that rotationally drives the tray protrusion member 53 to cause the i-rays 11 and 12 to protrude from the magazine body 8.

Further, the tray protruding member driving means, the chassis 16 as a supporting member, the moving member 18 (consisting of a movable chassis A19 and a movable chassis B20) as a first moving member, the tray protruding member 53, moving plates 37, 38, etc. The tray protruding member moving means constitutes a tray protruding means for protruding the tray 11 or 12 carrying the disc 10 to be played from the magazine body 8.

As shown in FIG. 10, a support 79 extending in the left-right direction (the direction of arrow
One of them is swingably attached to the movable chassis B20 at its left end via a bin 79a. The bin 79a extends in the front-rear direction (the direction of the arrow Y and the opposite direction), so the swinging direction of the seven supports is the same as the disk holding surface 23a of the turntable 23 (the 11th direction).
It is in a plane perpendicular to the figure (see b+).

At the free end of the support body 79, there is a disc-shaped pressing member 80 that comes into contact with the surface of the disc 10 opposite to the turntable 23 and cooperates with the turntable to perform a disc clamping action.
is rotatably attached. Further, 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.

With the support body 79 and the pressing part 4480 etc. described above,
A clamp mechanism is configured to clamp the disk.

As shown in FIG. 10, a bottle 79c extending forward is protruded from the free end of the support body 79, and the bottle is attached to a flat guide portion 72e at the rear edge of the upper surface of the second lever member 72. engaged. At the left end of the second lever member 72, which is an extension of the flat guide portion 72e, there is a pin 7 of the support 79.
A tapered portion 72f is formed so as to be engageable with 9c. As is particularly clear from FIG. 17, the tapered portion 72f is located on the left side (
It is inclined upward (in the direction of arrow Z) in the direction of arrow X). That is, with the forward movement of the second lever member 72 (movement in the right direction - counter-arrow X direction), the bottle 79c of the support base 79 slides on the flat guide portion 72e, and at this time the pressing member 8
0 is held at the clamp release position, and as the bottle 79C descends along the tapered portion 72f, the pressing member 80
is moved to the clamp position.

By the above-described clamp mechanism, the second lever member 72, and the drive mechanism (described above) that drives the second lever member,
The disc 10 supported on the tray 11 or 12 projected outside the magazine main body 8 by the tray projection means (described above) is placed on the disc supporting surface (the 11th
A disk moving means is configured to move in a direction perpendicular to the disk (see Figure (b)). Furthermore, the disk moving means and the tray projecting means provide a disk ejecting and conveying mechanism that sequentially selects any disks 10 to be pulled into the magazine 5 and conveys them onto the disk holding surface 23a of the turntable 23. Note that the second lever member 7

It is attached to the movable chassis Δ by movably engaging with a cam groove 19e formed in the cam groove 19e. 11th
As shown in Figure (b), the cam 119e 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 198 is formed so that when the disk holding member 83 moves left and right (C), the disk holding member 83 moves downward -F.

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 disc holding member 83, and one end 70e of the rotating intermediate lever 70
(See FIG. 10) pushes the right edge of this protrusion 83b, causing the disk holding member to move to the left (in the direction of arrow X).
It is made so that it can be moved to Incidentally, the disk holding member 83 is given a bias 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 moved onto the disk holding surface 23 of the turntable 23 by the disk moving means described above.
a (Refer to No. 11)), the lower surface of the disk that is moved in the direction (vertical direction) facing the disk supporting surface comes into contact with the disk, and the disk is moved against the disk supporting surface. This is to maintain parallelism.

The story goes back and forth, but as shown in Figures 6 and 8,
The inner surface of the right vertical surface 16c that is a part of the chassis 16 (
A pair of front and rear detection switches 86 and 87 are installed on the left side. Both detection switches 86 and 87 are
This is for detecting the moving position of the moving body 56 driven by 2. As is particularly clear from FIG. 8, each detection switch 86, 87 has actuators 86a, 87a that protrude obliquely from the switch body and swing.

A pair of rollers BB, 89, which are movable only in the vertical direction (in the direction of arrow 7 and the opposite direction) with respect to the chassis 16, are engaged with the free ends of these actuators 86a, 87a. 16+a+, (J shown in b+), each roller 88, 89 is engaged with a protrusion 56f having a trapezoidal cross section and extending in the front-rear direction on the lower surface of the front end of the movable body 56. In other words, by moving the moving body 56 a predetermined distance back and forth,
The rollers 88 and 89 are appropriately moved up and down by the action of the rollers 6f, thereby operating the detection switches 86 and 87. However, upward movement of the rollers 88, 89 is achieved by a bias applied to each actuator 86a, 67a by a bias applied means installed in each detection switch 86.8.

FIGS. 20 and 21 show a single adapter 90 that can be freely attached to the magazine mounting portion of the multi-disc player 1 and replaceably accommodates one disc 10 (see FIG. 3). It's a regular thing. As shown in the figure, the single adapter 90 includes a first member 91, a second member 92, and a first member 92 that are movable within a predetermined range in a predetermined direction (in this case, the front-rear direction, arrow Y direction, and the opposite direction). Has 3 parts and 93 months. A gear 94 is provided approximately at the center of the second member 92, and a rack portion 91a is formed on the first member 91 to extend in the front-rear direction.
It meshes with. Further, the first member 91 also has the third member 93.
A rack portion (not shown) facing the rack portion 91a is formed, and the gear 94 also meshes with the rack portion. A lever member 95 is swingably attached to the rear end of the first part 91 via a pin 95a, and the free end 95b of the lever member is pressed against the rear end surface of the second member 92. It is biased by a coil spring 96 so as to Further, the second portion 92 itself is also urged forward (in the direction of arrow Y) by another coil spring 97. That is, the second member 92 is moved against the first member 91 by the action of the coil springs 96 and 97 and the lever member 95.
Therefore, the third portion 93 is made to protrude forward by the action of the gear 94, the rack portion 91a, etc. However, the protrusion speed of the third member 93 is twice that of the second member 92. As shown in FIG. 21, a locking recess 93a that is locked by the locking member 67 shown in FIG. 10, for example, is formed at the right end of the third member 93 at the same position as the multi magazine 5. ing.

A bottle 93 extending upward is provided on the upper surface of the right rear end of the third member 93.
A plate-like tray C98 for supporting the disk 10 is installed in the bin so as to be swingable in the bin hole 98a. It is formed in approximately the same shape as the tray A11, and is made to protrude from the main body of the single adapter 90 by the tray protruding member 53 shown in FIG. A cover member 100 is installed.

Here, for example, the detection switch 34 shown in FIG.
35, that is, each detection switch for detecting that the magazine 5 is installed in the player body also detects the insertion of the single adapter 90 into the player body. However, as shown in FIG. 20, the bushing lever 32 (first
(See Figure 4) (I!! The part 100a of the cover member 100 that should be engaged with the end 32b is cut off, the push lever 32 does not swing, and therefore the detection switch 35 does not operate. Therefore, the left rear end corner of the first member 91 engages with the bushing lever 33.J:
Only the detection switch 34 operates, and the aforementioned control section does not consider this to mean that the single adapter has been installed.

Although not shown, the single adapter 90 includes a locking mechanism that locks the third member 93 and the second member 92 to the first member 91 when the single adapter is not installed in the player body. has been installed. 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 configured as described above will be briefly explained along the playing procedure with reference to FIGS. 22 and 23.

First, when a disc to be played is designated by operating the operation button group 6 shown in FIG.
starts moving forward (in the direction of arrow Y) or backward (in the opposite direction of arrow Y). Therefore, by the action of the stepped cams 1K37d and 38d formed on the movable play 1-37 and 38 and the guide Fi 16e formed on the chassis 16, the bin 20c movably fitted to each surface is moved up and down. The movable member 18 including the movable chassis B20 on which the bin 20c is protruded moves up and down. Accordingly, the first lay projecting member 53 provided on the moving member 18 reaches a position of engagement with the tray 11 or 12 carrying the disc to be played.

Here, the movement and positioning of the moving plate 37 back and forth,
Therefore, details regarding the vertical movement and positioning of the ray protrusion member 3) are given below.

The DCNT signals shown in FIGS. 22 and 23 are slit detection signals generated from the photosensor 51. In addition, the D Cl-I M signal is the movement play 1-3
7 is the detection signal emitted from the detection switch 49 which detects that the robot is at its most backward movement position (at the forward movement limit), that is, at the Baum position.

As shown in FIG. 22, the photosensor 51 is
If there is a movement command when the T signal is being issued, the ring hole address (current DISC) and desired address (search DISC)
The moving plate 37 is moved.Also, if there is a movement command while the photosensor 51 is not emitting the DCNT signal, the moving plate 37 is moved to the moving plate 1.
is moved back (moved forward) to the position of the desired address (search disc) until the detection switch 49 issues the DCl-IM signal.

In this way, when the tray protruding member 53 is positioned at the engagement position with the tray carrying the disc to be played,
Next, the motor 62 starts rotating, and the movable 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 moves rightward (counterclockwise in the direction of arrow X). 1st
As shown in FIG. 7, the second lever member 72
The first lever member 7 is
1 and is in a locked state. Therefore, the second lever member 71 also

12) protrudes from the magazine body 8, and the disc is attached to the disc supporting surface 23a of the turntable 23 (Fig.
b) to a concentric position with respect to (see b)), ie directly below the disk carrying surface. However, immediately before the rotation of the ray protruding member 53 and, therefore, the movement of the first lever member 71 to the right, the first and second
The lock state of the lever members 71 and 72 is released, and the subsequent slight rightward movement of the lever member 71 is caused by the biasing force of the coil spring 75, and the tray B12 is pushed by the biasing force. The positioning of the tray is completed when the arcuate portion 12d (see FIG. 3) contacts the predetermined arcuate contact portion of the movable chassis A19. The completion of ejection of the tray from the magazine main body 8 is detected by a detection signal from a detection switch 87 (see FIG. 8, etc.) which performs the following operation when the movable body 56 moves.

The second lever member 72, which has been released from the locked state with the second lever member 71, is further driven to the right (in the direction opposite to the arrow X) and is engaged with the tapered portion 72f of the second lever member 72 by the pin 79c. The support body 79 that is attached to the frame swings upward (in the direction of arrow 7). The disc is therefore lifted upwards and clamped against the turntable 23. Note that this upward movement of the disk is shown as DISC load in FIG. Further, as the disk moves upward, the disk holding member 83 also rises together with the disk due to the rotation of the intermediate lever 70. However, when the loading of the disc onto the turntable is completed, the disc pressing member 83 is slightly detached from the disc, and the disc pressing member does not interfere with the rotation of the disc.

In this way, it becomes possible to play, and the turntable 23 and carriage 24 (see FIG. 9, etc.) operate 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 two consecutive disc loading operations, so a detailed explanation will not be given. Thereafter, the above operation is repeated according to the designated number of songs.

Incidentally, the ejection operation of the magazine 5 to the outside of the player main body is performed by pressing the button for magazine ejection among the operation button group 6. When the magazine eject button is pressed, the movable body 56 (see, for example, FIG. 16) 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. Thereafter, the movable body 56 moves further forward, and as a result, the swing lever 64 shown in FIG. 6 swings about the swing support 64a and engages with the free end of the swing lever. The magazine 5 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 part 91 is released. At this point, push in roughly against the urging force of the coil springs 96 and 97. Then, the locking member 67 engages with the locking recess 93a provided in the third member 93.

Here, when a performance is instructed, the tray C98 is rotated and the performance is performed as in the case of the magazine 5. Here, when the listener wants to change the disc, he operates the same magazine eject button as when using the magazine. As a result, the tray C98 is rotated in the opposite direction in the same way as the magazine 5, and the locking member 67 is subsequently disengaged.

Then, the third member 93 protrudes forward (in the direction of arrow Y) by the action of the coil springs 96 and 97 until the tray C98 is completely exposed to the outside of the main body.

The listener now completes the disk exchange by simply replacing the disk on the tray with a desired one and pushing in the third member 93, so there is no need to remove the single adapter 90 again. In addition, if the third member 93 is pulled out further in the protruding state, this single adapter 90
It is also possible to remove the magazine and replace it with the magazine 5.

Effects of the Invention As detailed above, in the multi-disc player according to the present invention, there is a predetermined mechanism for conveying the performance disk (10) in a direction perpendicular to the disk supporting surface (23a) of the turntable (23). By moving the movable body (56), the magazine is unlocked from the player housing.

Therefore, the need for special unlocking means, such as an electromagnetic solenoid, for unlocking the magazine is eliminated, making it easier to downsize and reduce costs of the player.
