Abstract

PURPOSE:To smoothly move the second member with respect to the first member by making slightly large the sum of the extent of the first member protruding from a mounting part and the extent of the movement of the second member with respect to the first member than an outer diameter of a disk, and forming one of slidably contact parts of the first and the second members by a resin and the other by a metal. CONSTITUTION:When the second member 92 is moved with respect to the first member 91, the first member is protruded from an attaching part. The sum of the extent of the first member being protruded from the attaching part and the extent of the movement of the second member with respect to the first member is made slightly larger than an outer diameter of a disk 10. One of slidably contact parts of the first and the second members are made of resin and the other of metal. In this manner, the slidably contact parts are made of the combination of the resin and the metal, so that a friction coefficient is extremely small and no sliding noise is produced, but the movement of the second member with respect to the first member is smoothed.

Description

DETAILED DESCRIPTION OF THE INVENTION 1L1 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 of the stored discs for continuous play.

A jukebox is generally known as a disc player that can play a plurality of discs in succession. However, conventional jukeboxes have very large bodies, making them unsuitable for home use.

In recent years, it has been called a digital audio disc (hereinafter abbreviated as DAD), and by recording digital signals, it can accommodate an increased amount of information and playback speed compared to conventional analog audio discs. Several types of disks that generate less noise have been developed and are now in widespread use.

Of these, discs with an outer diameter of approximately 121mm, which is generally considered a compact disc, are easy to handle, and they record and read signals using radar light.
This makes it possible to downsize the entire disc player. Recently, I have been using multiple pieces of this small DAD (for example, 5 to 6 pieces).
A multi-disc player that can be stored at all times and is ideal for use as a home jukebox that plays these discs continuously has been developed. By the way, a small DAD has a performance time of one hour and can accommodate about 1.5 times as much information as a conventional analog audio disc. Therefore, for example, six discs can store about 120 songs with a performance time of around 3 minutes, and it is easy to cover them by your favorite genre, such as jazz or enka.

A multi-disc player basically consists of a playing means including a turntable and a pickup, a magazine that stores a plurality of discs arranged in order at a predetermined pitch, and a playing position by sequentially selecting any disc in the magazine.
In other words, it includes a disk ejecting and conveying mechanism that conveys the disk onto the turntable.

In the multi-disc player V that has already been developed, if you want to skip songs from a certain genre, such as jazz, you can store songs from other genres. Replace the disc containing the song with the stored magazine, or replace one of the discs in a magazine for another genre pulled out of the player housing with the disc you want to play, and then store the magazine back into the player housing. Something 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.

Recently, in an effort to improve the operability of loading and exchanging discs in disc players, a single adapter with the above configuration has been developed that is detachable from the magazine mounting section provided in the player body and stores one disc in a replaceable manner. A new multi-disc player has been developed. Figure 29 shows an outline of the developed single adapter, and Figure 30 shows a multi-disc player with this single adapter attached after the magazine (not shown) has been removed. be. As shown, a single adapter 13
0 is the player body 131 in which the magazine is installed.
The first member 1 is directly attached to the attachment part 132 provided in the
33, and a mounting portion 132 of the first member to the first member.

Note that the above-mentioned magazine (
A protruding means (not shown) is provided for protruding the single adapter 130 to the outside of the mounting portion 132 when exchanging the single adapter 130 (not shown) and the like.

The operation of the single adapter 130 described above will be briefly explained along the procedure of loading a disk.

First, by pressing an operation button (not shown) or the like, the second member 135 is moved relative to the first member 133 by the moving force applying means, as shown in FIG. protrudes to the outside of the player main body 131.

At this time, the above-described protruding means does not operate, and the first member 133 remains fixed to the mounting portion 132. When the second member 135 protrudes outside the player body 131, the disk 134 is placed on the disk supporting surface 136 of the second member, and the second member is pushed into the player body 131 again with a finger or the like. This completes loading the disc.

As mentioned above, the outer diameter of the disk 13/I: D is approximately 12C.
Since I+ (120 mm'), the protruding surface S of the second member 135 necessary for loading the disk is set to be slightly larger than this, for example, 125#lII+.

On the other hand, the single adapter 13 in the HW force direction 1-1
0 outer diameter dimension: Q is made approximately equal to the depth dimension of the mounting portion 132 from the viewpoint of compactness, etc.
When the member 135 protrudes, the first member 133 and the second
The length Q-8 over which the members 135 overlap is relatively small. As shown in FIG. 30, when a load of W is applied to a predetermined position of the second member 135 while the second member 135 is protruding, the first member 133 and the second member 13
A moment due to this load: W is applied to the portion where the numbers 5 overlap (the portion indicated by Q-8). However, as mentioned above, since the value of Q-3 is small, the strength of this portion is low, and there is a problem that the portion is easily deformed or destroyed.

11 to 1" The present invention has been made in view of the above-mentioned points, and its purpose is to provide a single adapter with sufficient strength against unexpected external forces, and to To provide a multi-disc player that can be smoothly moved.

The multi-disc player according to the present invention includes protruding means for protruding the magazine and the single adapter to the outside of a predetermined mounting part provided in the player housing for mounting the magazine and the single adapter, and the single adapter is attached to the VTFT part. a first member that is directly attached to the first member; and a second member that is slidable within a predetermined range within a predetermined range within the attachment force of the first member to the attachment portion and supports a disk.
a member, and a moving force applying means for applying a moving force to the second member, and when the second member is moved relative to the first member, the first member is caused to protrude from the mounting portion. , the sum of the amount by which the first member is made to protrude from the mounting portion and the amount by which the second member moves relative to the first member is slightly larger than the outer diameter of the disk;
One of the sliding contact portions of the first and second members is made of resin, and the other is made of metal.

FIG. 24 shows a single adapter 90 that is detachable from the magazine mounting portion of the multi-disc player 1 and that accommodates one disc 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 with respect to the first member along the mounting direction of the first member to the magazine mounting section. and a second member 92 that is slidable therein and carries a disk. The first member 91 is a combination of a rectangular bottom plate 93 and a top plate 94 having four semicircular parts 94a formed at its front end. The second member 92 also includes a sliding plate 95 that is freely removably attached to the first member 91 (the bottom plate 93 thereof), and a bottle 95a that is protruded from the right rear end of the sliding plate. The tray C96 is rotatable around the center and holds a disk 10 at tl11.

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).
A plurality of steel balls 95c are attached to a projecting portion 95b formed on a vibrating plate 95, which is a component of the second member 92.
is in smooth contact with this rail portion 93a. A linear opening 93C extending in the front-rear direction is formed in the center of the bottom plate 93, and a protrusion 95d protruding from the lower surface of the vibration plate 95 slides within the opening. A vibrating plate is guided.

The above-described projecting portion 95b and steel ball 95C are connected to the rail portion 93a.
A plate spring 93d made of a steel plate is arranged at a position sandwiching the base plate 93, and one plate spring 93d is attached to the main body of the bottom plate 93 with a screw 93e. This plate spring 93d forms a part of the bottom plate 93.

One of the mutual sliding contact portions of the angle 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 vibration 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 to extend in the front-rear direction. ) is this brake gear 98
It meshes with 8. The damper 98 applies braking force by utilizing the viscous resistance of a viscous agent such as grease held therein.

As shown in FIG. 24, a pressing lever 101 is provided at the left front end of the sliding plate 95 and extends substantially in the front-rear direction (direction of arrow Y and the opposite direction thereof). rIIlf via bin 95f! It is attached to the II plate 95 so as to be able to swing freely.

However, the bin 95f extends in the vertical direction (arrow Z direction and the opposite direction). The rear end of the pressing lever 101 can smoothly engage 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. The pressing lever 101 and the spring member 101a constitute a holding mechanism that holds the tray C96 at the storage position within the sliding plate 95.

As shown in FIG. 26, when moving the second member relative to the first member 91 without placing the disk 10 on the second member 92 (the tray C96 which is a constituent member thereof),
The first member 91 is also made to protrude outside the magazine mounting portion within 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, for example, the swing lever 64 and the spring 64d shown in FIG. It will be done. Note that the first member 91 and the second member 92 are locked in the magazine mounting portion by a locking member 67 shown in FIGS. 6 and 19 (ω).

As is clear from FIG. 26, the first member 91 is ff1 (for example, 50 mt
s ) and the amount of movement of the second member 92 relative to the first member 91 (for example, 75 m) (125 m+) is the disk 10
It is designed to be slightly larger (5 m2) than the diameter (120 am). With this configuration, the dimension indicated by U in FIG. 26, that is, the second member 92 (tray C96 thereof) can be protruded from the magazine mounting portion in order to attach and detach the disk 10 to and from the second member 92 (tray C96 thereof). The overlapping dimension of the first member 91 and the second member 92 when the two members are in contact with each other is relatively large.

It should be noted that the storage position of one disk 10 in the single adapter 90 described above is magazine 5 (11th!!I'

-50= The position of the disc corresponds to approximately the position of the middle husband's disc. As a result, the disk loading state with respect to the single adapter 90 is stabilized, and the first and second members 91
．． The aesthetic appearance of external fitting can be obtained when 92 protrudes outside the magazine mounting portion.

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 main body, also detects the installation of the single adapter 90 into the player main body. Specifically, the overhang 33 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 should abut against the rear end of the magazine 5. With this configuration, the moving lever 3 is different when the single adapter 90 is attached and when the magazine 5 is attached.
3 changes, the on/off state of each detection switch 34, 35 changes, and thereby it is determined which of the single adapter 90 and the magazine 5 is attached.

Although not shown, the single adapter 90 is provided with a locking mechanism that locks the second member 92 to the first member 91 when the single adapter is not installed in the player body. . 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 with the playing procedure with reference to FIGS. 27 and 28.

First, when a disc to be played is designated by operating the operation button group 6 shown in FIG. Start moving backwards (counter to arrow Y direction). Therefore, by the action of the stepped cam grooves 376.38d formed in the moving plates 37.38 and the guide grooves 16e formed in the chassis 16, the bin 20c movably fitted in the trapezoid is moved up and down. As a result, the moving member 18 including the movable chassis 820 on which the bottle 20c is protruded moves up and down. The tray protruding member 53 provided on the moving member 18 thus reaches a position of engagement with the tray 11 or 12 carrying the disc to be played.

Here, the movement and positioning of the front of the moving plate 37, and therefore 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 photosensor 51. Further, the DCHM signal is a detection signal emitted from the detection switch 49 that detects that the moving plate 37 is at its most backward movement position (forward movement limit position), that is, the home position.

As shown in FIG. 27, the photosensor Fj51 is
If there is a movement command while the NT signal is being issued, the current address (current DISC) and desired address (search DISC) will be displayed.
) The moving plate 37 is moved by a distance corresponding to the difference between the two. Furthermore, if a movement command is received while the photosensor 51 is not emitting the DCNT signal, the moving plate 37 is moved back (forward) until the detection switch 49 issues the DCHM signal, and then moves to the desired address ( search DISC).

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). Second
0, the second lever member 72 is connected to the movable piece 7.
The first lever member 7 is
1 and is in a locked state. Therefore, the second lever member 71 also
The lever member 72 moves to the right, thereby rotating the tray protruding member 53, for example, clockwise in FIG. 10. Therefore, as shown in FIG. 2+b+, a tray (eg tray B1
2) protrudes from the magazine body 8, and the disk moves to a position concentric with the disk supporting surface 23a (see 11th reading) of the turntable 23, that is, to a position directly below the disk supporting surface. However, just before the rotation of the tray protruding member 53 and, therefore, the rightward movement of the second lever part 1471 is completed, the locked state of the first and second lever members 71 and 72 by the locking/releasing means is changed. After the release, the slight rightward movement of the first lever member 71 is caused by the coil spring 75 (
The arcuate portion 12e (see FIG. 2Cb)) of the tray B12 pushed by the urging force is applied to the predetermined arcuate contact portion 1 of the movable chassis Δ19.
By abutting against 9C, the positioning of the tray is completed.

Note that 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.) activated by movement of the movable body 56.

The second lever member 72, which has been released from the locked state with the first lever member 71, is further driven to the right (in the direction opposite to the arrow Support 79 of the clamping mechanism engaged by 79c
(shown in Figure 10) swings upward (in the direction of arrow Z). The disc is thus lifted upwards and clamped against the turntable 23. Note that this upward movement of the disc is shown as Disc Load in FIG. Further, as the disk moves upward, the rotation of the intermediate lever 70 causes the disk holding member 8 to
3 also rises with the disc.

However, when the loading of the disk onto the turntable is completed, the disk holding part 083 is slightly separated 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 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 above operation is repeated according to the specified 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 (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. As a result, the swing lever 64 shown in FIG. 10 etc. swings about the bin 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 locking member 67 engages with the locking recesses (not shown) provided in the first and second members 91 and 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 disc, he operates the same magazine eject button as when using the magazine. As a result, the tray C96 is rotated in the opposite direction in the same way as the magazine 5, and the locking member 67 is subsequently 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. Here, the listener replaces the disc on the tray with a desired one and replaces the second member 92 with the first member 91.
Since disk replacement is completed by simply pushing the single adapter 90 together, there is no need to remove the single adapter 90 again. Further, in the protruding state of the first and second members 91 and 92, by further pulling them out, the single adapter 9o can be removed and replaced with the magazine 5.

Effects of the Invention As detailed above, the multi-disc play V according to the present invention has a magazine (5) and a single adapter (
90) includes a protruding means (consisting of a swing lever 64 and a coil spring 64d) for protruding the magazine and single adapter to the outside of a predetermined mounting part provided in the brake V housing (2) as a mounting part; The adapter includes a first member (91) that is directly attached to the attachment part;
a second member (92) that is slidable within a predetermined range along the mounting direction of the first member to the mounting section and supports a disk; and a moving force is applied to the second member. and a moving force applying means (coil spring 97) for applying the second
When the member is moved relative to the first member, the first member is caused to protrude from the mounting portion, and the first member is caused to protrude from the mounting portion, and the second member is attached to the first member. The sum of the amount of movement is set to be (φ) larger than the outer diameter of the disk.

Therefore, the overlapping dimension of the first member and the second member (the 26th
This is because the dimension (indicated by U in the figure) is larger. Therefore, the strength of this overlapping portion is sufficient, and even if an unexpected external force is applied to the second member protruding from the upper mounting portion, the overlapping portion will not be deformed.

Further, in the multi-disk play 17 according to the present invention, one of the mating sliding contact portions of the first and second members is made of resin, and the other is made of metal. When both members that slide into contact with each other are made of metal, for example, the coefficient of friction is large and a sliding sound is generated. As described above, in the multi-disc player according to the present invention, since the sliding contact portion is made of a combination of resin and metal, the coefficient of friction is extremely small, and the movement of the second member relative to the first member does not generate any sliding noise. is done smoothly.
