Abstract

PURPOSE:To improve the operability of the loading and replacement of a disk by providing a couple of push levers which engage a magazine at an interval of the thickness of the magazine and a detection switch which engages them with the innermost part of a magazine loading part. CONSTITUTION:The loading of the magazine and a single adapter 90 in a player body is detected through switches 34 and 32. Part 100a of a cover 100 which engages the swing end part 32b of a push lever 32 is cut to prevent the lever 32 from swinging, thus preventing the switches from operating. Consequently, the right rear end of a member 91 engages a push lever 33 and only the switch 34 operates, so that a control part regards this state as the loading completion of the single adapter 90. When the adapter 90 is not loaded in the player body, a mechanism which is not shown in a figure, locks members 93 and 92 are locked to the member 91 and when the adapter is loaded, they are unlocked. Thus, the operability of the loading and replacement of a disk is improved.

Description

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

Background Art A jukebox is generally known as such a disc player 17. However, conventional jukeboxes were originally very large, making them unsuitable for use as home entertainment.

In recent years, it has been called a digital A-D A disc (hereinafter abbreviated as DAD), and by recording digital signals, it can accommodate an increased amount of information compared to the conventional A-Dio disc, which recorded analog signals. Several types of disks have been developed and widely used, which are flexible and generate less noise during playback.

Among these, disks with an outer diameter of about 12C11, 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. What should I do? Recently, multiple small DADs (for example, 5 to 6
A multi-disc player has been developed that is ideal for use as a jukebox for home music, which can store discs at all times and play these discs continuously. By the way, the compact DAII has a playing time of 1 hour, which is about 1 hour longer than a conventional analog audio disc.
．． It can accommodate five times the amount of information. Therefore, for example, six discs can store about 120 songs with a performance time of around 3 minutes, and it is easy to organize them by genre of your choice, such as jazz or enka.

A multi-disc player basically consists of a playing means including a turntable, a pickup, etc., a magazine that stores a plurality of discs arranged in order at a predetermined pitch, and 1) any discs placed in the magazine that are sequentially selected. It is equipped with a disc ejecting and transporting mechanism for transporting the disc onto the turntable from the performance position.

With the already developed Multi-Disc Player It is possible to replace the disc that has been played with the stored magazine, or replace one of the discs in a magazine for another genre that has been pulled out of the play 17 housing with the disc that you want to play, and then store the magazine in the player housing again. It was being done. Furthermore, if there are a plurality of desired disks, the above-described replacement operation must be performed for each disk. Therefore, the operability of changing the disc is poor, and the listener feels troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a multi-disc player with good operability in loading and exchanging discs in the player.

It should be noted that the slight movement of the second lever member 71 to the forward most forward position after being released from the locked state with the second lever member 72 is performed by the biasing force of the coil spring 75 mentioned above. In addition, during the slight movement of the first part of the shrine, the arcuate parts 11d and 12d of the tray 11.12 (Figs. 4 and 5
) is brought into contact with an arc-shaped predetermined contact portion 19c (see FIGS. 6 and 10) formed on the movable chassis Δ19, and the disc 10 carried on the tray is brought into contact with the disc of the turntable 23. It is positioned concentrically with respect to the supporting surface 23a (see 11th outlet) (◇ position J-, that is, directly below the disk supporting surface).

The second lever includes the locking/releasing means described above (consisting of the rotatable member 76, etc.), the first and second lever members 71, 72, the coil spring 75 serving as the urging means, the movable body 56, the motor 62, etc. The drive mechanism that drives the lever member 72 (described above)

Further, the tray protruding member driving means, the chassis 16 as a supporting member, the moving member 18 as a first moving member (consisting of a movable chassis Δ19 and a movable chassis 120), a tray protruding member 53, and a moving plate 37, 38 A tray projecting means for projecting the tray 11 or 12 carrying the disc 10 to be played from the magazine body 8 is constituted by the tray projecting member moving means.

As shown in FIG. 10, a support 79 extending in the left-right direction (the direction of arrow
-C is provided and is swingably attached to the movable chassis B20 at its left end via a bin 79a. The pin 79a extends in the front-rear direction (arrow Y direction and the opposite direction), so the swinging direction of the support body 79 is the same as the disk holding surface 23a of the turntable 23 (
(See Figure 11+b+).

At the free end of the support body 79, there is a disc-shaped suppressing part U80 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 mounted t-j. Further, although not shown, a spring is provided that urges 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, suppressing member 80, etc. constitute a clamping mechanism that clamps the disk.

As shown in FIG. 10, a bottle 79C that extends forward is protruded from the free end of the support 79, and the bottle is attached to the flat guide portion 72e at the rear edge of the upper surface of the second lever member 72. engaged. A bottle 79 of the support body 79 is located on the left end of the second lever member 72 on the extension of the plane guide portion 72e.
A tapered portion 72f is formed so as to be engageable with c. 1st
It is particularly clear from Fig. 7 that the tapered portion 72f is located on the left side (
It is inclined upward (in the direction of arrow 7) in the direction of arrow X). That is, as the second lever member 72 moves forward (moves rightward in the direction of the arrow 8
0 is held at the clamp release position, and the bottle 79C is lowered along the tapered portion 72 (by which 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 part l,
The disk 10 supported on the tray 11 or 12 that is protruded out of the magazine body 8 by the tray ejecting means described above is moved in a direction perpendicular to the disk supporting surface of the turntable 23 (see 11th appearance). A disk moving means is configured. Further, the disk moving means;
The tray protruding means sequentially selects any disc 10 in the magazine 5 and moves it onto the turntable 23.
A disk ejecting and conveying mechanism is constructed on the disk holding surface 23a. Note that the second lever member 72 and
The drive machine 1f4 (described above) which drives the second lever is used both as the ray ejecting means and the disk moving means.

As shown in FIGS. 6, 9, and 10, the movable chassis Δ19 and the movable chassis B, which constitute the moving member 18,
A plate-shaped disk holding member 8 is sandwiched between the plate-shaped disk holding member 8 and the

As is clear from FIGS. 9 and 10, a projection 83t+ extending downward is provided on the lower surface of the right rear end of the disc pressing member 83.
is formed, and one end 70 of the intermediate lever 70 rotates.
e (see FIG. 10) presses the right edge of the protrusion 83 [1], thereby moving the disk holding member to the left (in the direction of arrow X). Incidentally, the disk holding member 83 is biased toward the right (in the direction opposite to the arrow Xh) by a coil spring 84 shown in FIG. 9, for example.

The above-mentioned disk holding member 833 is moved to the disk supporting surface 2 of the turntable 23 by the disk moving means described above.
3a (see Fig. 11 (b+)) The lower surface of the disk that is moved in the direction perpendicular to the disk supporting surface (vertical direction) comes into contact with the surface facing the disk supporting surface. This is to maintain the parallelism of .

The story goes back and forth, but as shown in Figures 6 and 8,

A pair of front and rear detection switches 86 and 87 are marked on the left side. Both detection switches 86 and 87 are for detecting the movement position of the moving body 56 driven by the motor 62. As is especially clear from Figure 8,
Each of the detection switches 86 and 87 has one swinging actuator 86a, 87a that projects diagonally from the switch body. A pair of 1-ra 88, 89 provided on the body 1 that is movable only in the vertical direction (arrow // direction and the opposite direction) with respect to the chassis 16 are connected to the free ends of these actuators 34 = 86a, 87a. is engaged with the part.

In addition, each detection switch 34, 35, 49, 86 mentioned above
The detection signals emitted from the photosensors 51 and 87 are transmitted to the aforementioned control unit (not shown), and the motors 27, 45, 62 and 87 are controlled by operation signals sent from the control unit in response to these detection signals. The turntable 23 changes its operation at a predetermined timing, which will be described later.

20 and 21 show the multi-disc play V
This figure shows a single adapter 90 that replaceably accommodates one disk 10 (see FIG. 3) in one magazine mounting portion. As shown in the figure, the single adapter 90 has a first part 4A91 and a second part that are movable relative to each other within a predetermined range in a predetermined direction, in this case, the front-rear direction (arrow Y direction and the opposite direction).
It has a part 92 and a third member 93. Second member 92
A gear 94 is provided approximately at the center of the rack section 94, which is formed on the first member 91 and extends in the front-rear direction.
It meshes with 1a. The third member 93 also has a rack portion (not shown) that faces the rack portion 91a of the first member 91.
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 4A91 via a pin 95a, and the free end 95b of the lever member is attached to the rear end surface of the second member 920. It is urged by a coil spring 96 so as to be pressed. In addition, the second member 92 itself is also turned forward (=J vl) by other springs 97 and 75 (in the direction of the arrow Y). The second
The member 92 is made to protrude forward with respect to the first part 91, and therefore the third member 93 is made to protrude forward by the action of the gear 94, the rack part 91a, etc. However, the protrusion speed of the third member 93 is the same as that of the second member 92.
This is twice the ejection speed. Note that, as shown in FIG. 21, the right end of the third member 93 has a locking recess 9 that is locked by the locking member 67 shown in FIG. 10, for example.
3a is formed at the same position as the multi magazine 5.

The right rear end of the third member 93 - the upper surface has a bottle 9 extending upward;
A plate tray C98 carrying a disk 10 is swingably attached to the bin through a bin hole 98a. For example, the tray C98 is formed in approximately the same shape as the tray A11 shown in FIG.
It is made to protrude from the main body of the single adapter 90 by a tray protrusion member 53 shown in FIG. In addition, the third
A cover 44100 (number 44100) is provided on the upper surface of the tray 93 to cover the tray CQ8.

Here, for example, the detection switch 34 shown in FIG.
35, that is, each detection switch for detecting that the magazine 5 is installed inside the player body also detects the installation of the single adapter 90 inside the player body. However, as shown in FIG. As shown, the push lever 32 (the first
A portion 100a of the cover member 100 that should be engaged with the other swinging end 32b of the push lever (see Figure 4) is cut off, so that the push lever 32 cannot swing and therefore the detection switch 35 does not operate. . Therefore, when the left rear end corner of the first member 91 engages with the push lever 33, only the detection switch 34 is operated, and the aforementioned control section considers this to be the completion of mounting the single adapter.

Although not shown, the single adapter 90 has a mechanism for locking the third member 93 and the second member 92 with respect to the first member 91 when the single adapter is not installed in the player body. A one-click mechanism is provided. This locked state by the one-click 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 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 376.38d formed on the moving plate 37.38 and the guide 16e formed on the chassis 16, the bin 20c movably fitted into the multiple grooves is moved up and down. The movable member 18 including the movable chassis B20 on which the bin 20G is protruded moves downward. Therefore, the tray protruding 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, the vertical movement and positioning of the tray protruding member 53 will be described in detail.

The DCNT signal shown in FIGS. 22 and 23 is a slit detection signal generated from the photosensor 51. In addition, the D C)-IM signal is the moving plate 37
This is a detection signal emitted from the detection switch 49 which detects that the vehicle is at its most backward movement position (forward movement limit position), that is, the home position.

As shown in FIG. 22, the photosensor 51 is
If there is a movement command while the T signal is being emitted, the current address (current disc) and desired address (reach disc)
The first plate 37 is moved by a distance corresponding to the difference between G'j and G'j. In addition, even if a movement command is received while the photosensor 51 is not emitting the CN T signal, the moving plate 37 moves back (forwardward movement) 1 until the OCl-IM signal is emitted from the detection switch 49. ! After that, the disc is moved to the desired address (reach disc).

When the tray protruding member 53 is positioned at the engagement position with the tray carrying the disc to be played, the motor 62 starts rotating and the movable body 56 moves backward (
(opposite arrow Y direction).

Therefore, the intermediate lever 70 is rotated as shown in FIG.
direction), and the second lever member 72 connected to the intermediate lever moves to the right (counter to the direction of arrow X).

As shown in FIG. 17, the second lever member 72 is in a locked state with the second lever member 71 by means of a locking and releasing means consisting of a movable piece 76 and the like. Therefore, the first rubber member 71
The second lever member 72 and Jl also move to the right, thereby causing the tray protruding member 53 to rotate -4 in the direction h1 in FIG. 10, for example. Therefore, as shown in FIG.
-ray B12) protrudes from the magazine body 8, and the disk moves to a concentric position with respect to the disk supporting surface 23a (see Figure 11) of the turn desol 23, that is, directly below the disk 10. 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 and releasing means is changed. is canceled,
The subsequent slight rightward movement of the first lever part 4471 is performed by the biasing force of the coil spring 75, and the arcuate portions 12d (see FIG. 3) of the 1 to ray B12 pushed by the biasing force move into the arcuate shape of the movable chassis A19. The positioning of the tray is completed by contacting the predetermined contact portion.

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 locked state with the second lever member 71, is further driven to the right (in the direction opposite to the arrow The supporting body 79 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 first 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 disc loading operation described above, so a detailed description thereof will not be given. Thereafter, the operations described in "-" are 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 portion 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 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, as in the case of the magazine 5, the tray C98 is rotated and the performance is performed. Here, when the listener wants to change the disc, he operates the same magazine input button as when using the magazine. As a result, similarly to the case of the magazine 5, the lay C98 is rotated in the opposite direction, and the engagement of the rack member 67 is subsequently released.

Then, the third member 93 becomes a coil spring 96°970
As a result of this action, the tray C98 protrudes forward (in the direction of arrow Y) until it is completely exposed outside 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, when the third member 93 is in the protruding state, if you roughly pull it out, this single adapter 90
It is also possible to remove the magazine and replace it with the magazine 5.

As described in detail in ``Advantageous Effects of the Invention'' (2), in the multi-disc player according to the present invention, it is detected that the magazine (5) for sequentially arranging and storing a plurality of discs (10) is installed in the player housing (2). A magazine attachment detecting means is provided in the deep part of the magazine attachment portion at a distance corresponding to the thickness of the magazine, and engages with the magazine. It consists of a pair of push levers (32, 33) and a pair of detection switches (34, 35) that can be engaged with the push levers.

Therefore, it is possible to use a single adapter (90) that accommodates one disk of C1 and whose size is approximately the same as that of the magazine. That is, all of the pair of push levers and detection switches described above are used to detect the magazine, and one of the push levers (33) and detection switch (34) is used to detect the single adapter. 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 it is also extremely easy to replace discs, resulting in improved operability. -ing
