Abstract

PURPOSE:To improve the disk loading operability by regulating the shift of a traveling object with a lock member which can reciprocate freely between the 1st position where a disk holder is locked and the 2nd position where the lock of the disk holder is released. CONSTITUTION:A lock member 67 can reciprocate freely between the 1st position where a disk holder (magazine) 5 is locked and the 2nd position where the lock of the holder 5 is released. A part of the member 67 hooks the holder 5 to hook it. Furthermore the member 67 contains a means which energizes the lock member to secure the hook to the holder 5. Then the member 67 hooks a mobile object 56 at the 2nd position or in the vicinity thereof. Thus the shift of the object 56 is regulated. The member 67 is unable to move to the 1st position if the magazine 5 is not loaded completely to the loading part in a player housing. Therefore the shift of the object 56 is regulated and no disk is loaded.

Description

DETAILED DESCRIPTION OF THE INVENTION 1"Ll 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.

ui A jukebox is generally known as a disc player that can store a plurality of discs and can sequentially select any of the stored discs to play continuously. 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 CAD), and by recording digital signals, it is possible to increase the amount of information that can be stored compared to the conventional audio disc that contains analog signals, and it is easier to play. Several types of disks that generate less noise have been developed and are widely used.

Among these, discs with an outer diameter of approximately 12 cm, which are generally called compact discs and which record and read signals using laser light, are easy to handle and allow the entire disc player to be made smaller. be. Recently, I have been using multiple pieces of this small DAC (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 approximately 1.5 times more information m than 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 includes a playing means including a turntable, a pickup, etc., a disc holder that holds a disc and is inserted into a mounting part in the player housing, and a disc in the disc holder that is placed at a playing position. In other words, it is equipped with a disk ejecting and conveying mechanism that conveys the disk onto the turntable.

In a multi-disc player, when a disk in a disk holder is conveyed onto a turntable, the disk is moved in two directions, for example, in a direction parallel to the disk supporting surface of the turntable and in a direction substantially perpendicular thereto. However, in the multi-disc player developed in 2), the disc ejecting and transporting mechanism for carrying out this transport directly picks up the disc in the disc holder, either at the end of the disc in the direction in which it protrudes from the disc holder, or at approximately the entire disc. The structure of the disc ejecting and transporting mechanism, including the gripping mechanism that grips the disc, is large and complicated, and the space required for its operation is large, making it difficult for players to It has been difficult to downsize the entire device, and this has led to an increase in cost.

Recently, in an attempt to solve this problem, for example, the patent application
No. 04310, the disc holder comprises a housing, arranged in the housing in a direction substantially perpendicular to the disc carrying surface of the turntable, each carrying a disc on its major surface, and having a disc holder arranged in the housing in a direction substantially perpendicular to the disc carrying surface of the turntable; On the other hand, a new multi-disc player has been developed that includes a plurality of plate-shaped trays that can be protruded and stored along each main surface. That is, the disc is configured such that the disc is transported in one direction (the disc is transported in a direction parallel to the disc-supporting surface of the turntable) by simply protruding the plate-shaped trays each carrying a disc from the housing. -ing Therefore, in a multi-disc player as described above, a disc stored in a disc holder is directly gripped by the protruding end of the disc from the disc holder or substantially the entire disc by a complicated gripping mechanism, and then removed from the disc holder. The structure is simpler than that provided with a pull-out type disc ejecting and transporting mechanism, and it becomes easier to reduce the size and cost of the player as a whole.

The specific structure of the disc ejecting and transporting mechanism that feeds the disc in two directions includes a tray projecting means for projecting the tray carrying the disc to be played from the housing of the disc holder, and a tray projecting outside the housing. a disk moving means for moving the disk supported thereon in a direction substantially perpendicular to the disk supporting surface of the turntable, and the tray protruding means includes a support member extending along the arrangement direction of each of the trays; , a movable member movably provided on the support member in the arrangement direction and carrying performance means (a turntable, a pickup, etc.); and one of the trays provided on the movable member movably in a predetermined direction. a tray protruding member that engages with each other to cause the tray to protrude outside the housing of the disc holder; and a tray protruding member that is moved together with the moving member to a position where it engages with a tray carrying a disc to be played. It has a tray protruding member moving means, and a tray protruding member driving means for driving the tray protruding member to cause the tray to protrude from the housing.

That is, by moving the entire performance means including the turntable, pickup, etc. along with the moving member carrying the performance means along the arrangement direction of each of the trays, the relative relationship between each tray and the turntable in the tray arrangement direction is reduced. Also, by driving and moving the tray protruding member, each of the trays is pushed and protruded out of the housing of the disc holder, and the disc on this tray is moved directly below the turntable. It has a structure that allows it to be located in

SUMMARY OF THE INVENTION It is an object of the present invention to provide such a multi-disc player, and in particular, to provide a multi-disc player with good operability regarding disc loading.

A multi-disc player according to the present invention includes a locking mechanism that holds a disc and locks a disc holder inserted into a mounting portion in a player housing at the mounting position with respect to the player housing, and a disc to be played. tray protruding member driving means for driving the tray protruding member to cause the tray to protrude from the housing of the disc holder, the tray protruding member driving means being movable in a predetermined direction and configured to drive the tray protruding member. The locking mechanism includes a moving body and a driving force applying means for applying a driving force to the moving body, and the locking mechanism reciprocates between a first position where the disc holder is locked and a second position where the locked state is released. A locking member that is freely disposed and locks the disc holder by engaging a portion of the locking member with the disc holder, and an urging member that biases the locking member so that the locking member engages with the disc holder. means, wherein when the lock member is in the second position and in the vicinity thereof, the lock member engages with the movable body to restrict movement of the movable body. It is said that

By doing so, even if the single adapter is placed carelessly on a desk or the like, the lever member 103C will not engage with the machine surface, and the locking mechanism will prevent the lever member 103C from engaging with the machine surface. The locked state f) of the second part 4492 relative to the first member 91 is maintained.

As shown in FIG. 25, the front end of the locking member 103 is provided with a lever member 103C as well as a manual release button 103e for manually releasing the locked state of the WX2 member 92 to the first member 91 by the locking means. are integrated. As shown in FIG. 26, the manual release button 103e is exposed outside the single adapter through an opening formed in the bottom plate 93, so that the manual release button 103e can be pressed with a finger or the like.

Further, the pressed surface of the manual release button 103e is aligned with the surface of the bottom plate 93 or is positioned inward from this surface. By doing so, even if the listener carelessly places the single adapter 90 on a desk or the like, the manual release button 103e will not be pressed by the placing section, and the locking mechanism will not release the manual release button 103e. 1 member 91
The locked state of the second member 92 is maintained.

As shown in FIGS. 24 and 25, at the left rear end of the top plate 94, which is a component of the single adapter 90,
For example, a recess 94cS is provided into which an overhang 64b provided at one end of the swinging lever 64 shown in FIG. 13 can fit. That is, when the single adapter 90 is inserted into the mounting portion in the player housing 2 in the correct posture (the posture shown in FIG. 24), the swinging lever 64 smoothly moves the projecting portion 64b with the single adapter. However, if the single adapter 90 is upside down and the mounting position is incorrect, the swing lever 6
The overhanging portion 64b of No. 4 fits into the recess 94c, and when the single adapter is inserted into the mounting portion and the swing lever 64
The oscillations of the two are balanced, and therefore, the single adapter is prevented from being attached.

In addition, as shown in FIG. 25, the single adapter 9
A locking recess 95k into which the rotating end 67a of the locking member 67 shown in FIG.

As shown in FIG. 28, when moving the second member 92 relative to the first member 91 in order to place the disk 10 on (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 player housing 2. However, the movement of the second member 92 relative to the first member 91 is performed by a coil spring 97b, and the protrusion of the first member 91 from the mounting portion is performed by, for example, the swing lever 64 and coil spring 64d shown in FIG. . Note that the first member 91 and the second member 92 are locked in the magazine mounting portion.
This is done by a locking member 67 shown in FIG. 9 (ω).

As is clear from FIG. 28, the first member 91 has a base (for example, 50m+) that protrudes from the mounting portion, and a second
The amount of movement of the member 92 relative to the first member 91 (for example, 75
rnlR> (125 INR) is slightly larger (5 m) than the diameter of the disk 10 (120 m+). With this configuration, the 28th
The dimensions indicated by U in the figure, that is, the dimensions between the first member 91 and the second member 92 (tray C96 thereof) when the second member is protruding from the 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 two members 92 is relatively large.

Note that the storage position of one disk 10 in the single adapter 90 described above is in the magazine 5 (Figs. 1 to 5).
Of the six discs housed in the disc (see figure), the position corresponds approximately to the position of the middle disc. This stabilizes the disk loading state in the single adapter 90, and provides an aesthetic appearance when the first and second members 91, 92 protrude 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 in the play V 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 9o that is to come into contact with g (the rear end of the magazine 5 comes into contact with this). With this configuration, the moving lever 3 is different when the single adapter 90 is installed and when the magazine 5 is installed.
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.

Next, the operation of the multi-disc player configured as described above will be briefly explained along the playing procedure with reference to FIGS. 29 and 30.

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 37d and 38d formed in the moving plates 37 and 38 and the guide groove 168 formed in the chassis 16, the bin 20c, which is movably fitted in the groove, moves up and down. The movable member 18 including the movable chassis B20 on which the bin 20c is protruded moves up and down. Therefore, the tray projecting member 53 provided on the movable member 18 reaches the engagement position 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.

D CNT (No. 8 shown in FIGS. 29 and 30 is the slit detection signal emitted from the photosensor 51. Also, the DCHM signal is the slit detection signal emitted from the photo sensor 51.
This is a detection signal emitted from the detection switch 49 that detects that the motor is at its most backward movement position (forward movement limit position), that is, the home position.

As shown in FIG. 29, the photosensor 51 is
If a movement command is issued while the T signal is being issued, the current address (current DISC> and desired address (search DISC)
The moving plate 37 is moved by a distance corresponding to the difference. Furthermore, if a movement command is issued while the photosensor 51 is not emitting the DCNT signal, the moving plate 37 is moved backwards and forwards until the DCHM signal is emitted from the detection switch 49, and then is moved to the desired address (search D).
isc).

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
The lever member 72 moves to the right (counter to the direction of arrow X). As shown in FIG. 20, the second lever member 72 is in a locked state with the first lever member 71 by a locking/releasing means comprising a movable piece 76 and the like. Therefore, the first lever member 71 also moves to the right together with the second lever member 72, thereby causing the tray protruding member 53 to rotate, for example, clockwise in FIG. 10. Therefore, as shown in FIG.
2) protrudes from the magazine body 8, and the disk moves to a position concentric with the disk supporting surface 23a (see the peak in FIG. 11) 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 first lever member 71 is completed, the locked state of the first and second lever members 71 and 72 by the lock/release means is changed. After the release, the slight rightward movement of the first lever 71 is performed by the biasing force of the coil spring 75 (see FIG. 20, etc.), and the arc-shaped portion 121 (second ) is the arc-shaped predetermined contact portion 19c of the movable chassis A19.
By making contact with the tray, 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 79G
(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 disk 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 will also go up with the disc.

However, when the loading of the disc onto the turntable is completed, the disc pressing member 83 is slightly separated 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 above operation is repeated according to the specified number of songs.

Incidentally, the ejecting operation of the magazine 5 to the outside of the main body of the play 17 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. With this, the 10th
A swinging lever 64 shown in the figures swings around the bin 64a, and the magazine 5 engaged with the free end of the swinging 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 7 adapter 90 is inserted into the insertion port 3a. At this time, the locking means (described above) that locks the second member 92 with respect to the first member 91 is released.

Here, against the urging force of the coil spring 97,
Push it in further. Then, the locking member 6 is inserted into the locking recess 95k provided in the sliding plate 95, which is a component of the second member 91.
7 engages.

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 096 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 completes the disc replacement by simply replacing the disc on the tray with the desired one and pushing the second part 92 together with the first Fg3 material 91, so there is no need to remove the single adapter 90 again. do not have. 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.

As described in detail above, in the multi-disc player according to the present invention, the disc holder (magazine 5), which holds the discs and is inserted into the mounting section in the player housing, is placed in the mounting position relative to the player housing. and a tray protruding member driving means for driving a tray protruding member (53) to protrude a tray carrying a disc to be played from the housing of the disc holder, and the tray protruding member driving means is configured to operate in a predetermined manner. The locking mechanism includes a movable body (56) that is movable in the direction and drives the tray protrusion member, and a driving force applying means that applies a driving force to the movable body, and the locking mechanism locks the disc holder. a locking member (67) that is provided so as to be reciprocally movable between a first locking position and a second position releasing the locked state, and locks the disc holder by a part of the locking member engaging with the disc holder; and a biasing means for biasing the a-lock member so that the lock member engages with the disc holder, and when the lock member is in the second position and in the vicinity thereof, the lock member The movement of the movable body is restricted by engaging with the movable body.

That is, when the disc holder (magazine 5) is not completely installed in the mounting section within the player housing, the locking member cannot move to the first position, thereby restricting the movement of the moving body. It is configured so that no disk loading operation is performed. If it is not configured in this way, the movable body will move and perform the disc loading operation even if the listener does not completely install the disc holder into the mounting section, and for example, the tray protruding member (53) Therefore, there is a concern that a situation may occur in which the trays (11, 12> projected outside the housing (magazine body 8) of the disc holder (magazine 5)) get caught on a chassis or the like provided within the player housing. In the multi-disc player according to the present invention, such inconvenience does not occur, and disc loading is always performed reliably.In other words, the operability regarding disc loading is excellent.
