Description

DETAILED DESCRIPTION OF THE INVENTION 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.

2. Description of the Related Art A jukebox is generally known as a disc player that can store a plurality of discs and can sequentially select any stored disc 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 DAD), 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. Discs that generate less noise during recording have been developed and are now widely used.

In addition, this method uses a laser beam to record and read signals, and the disk with an outer diameter of about 12 cm, commonly called a compact disk, is easy to handle and allows the overall size of the disk player to be made smaller. It is. 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 approximately 1.5 times the amount of information as a conventional analog audio disc. Therefore, for example, 6 discs can accommodate approximately 120 songs with a playing time of around 3 minutes, and can accommodate your favorite songs such as jazz or enka. It also makes it easier to cover each category.

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 that has already been developed, the above-mentioned disk ejecting conveyance n lateral for carrying out this conveyance directly transfers the disk in the above-mentioned disk holder to the end of the disk in the direction in which the disk protrudes from the disk holder or approximately the entire disk. The configuration 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 is difficult to miniaturize the entire device and the cost increases.

Recently, in an attempt to solve this problem, for example, the patent application
No. 04310, the disc holders may be arranged within a housing in a direction substantially perpendicular to the disc carrying surface of the turntable, each carrying a disc on its major surface, and each with respect to the housing. A new multi-disc player has been developed that includes a plurality of plate-shaped trays that can be protruded and stored along the 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 the above-mentioned multi-disc player, the disc stored in the disc holder is directly gripped by the protruding end of the disc from the disc holder or by the approximate entire body of the disc using a crude gripping mechanism. Compared to the one with an external pull-out disk ejecting mechanism, the configuration is better. fi m, making it easier to reduce the size and cost of the Play V 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 extending along the arrangement direction of each of the trays. a member, and a playing means (
a turntable, a pickup, etc.); and a movable member that is movably provided on the movable member in a predetermined direction and engages each of the trays one by one to move the tray to the outside of the housing of the disc holder. a tray protruding member for causing the disc to protrude; and a tray protruding member moving means for moving the tray protruding member together with the moving member to a position where it engages with the tray carrying the 8Ii disc to be played;
and tray protrusion member driving means for driving the tray protrusion 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. The tray protruding member is driven to move the tray protruding member, thereby pushing each tray to protrude the tray out of the housing of the disc holder, and causing the disc on this tray to turn as described above. The structure is such that it is located directly below the table.

SUMMARY OF THE INVENTION The object of the present invention is to provide such a multi-disc player, which has good vibration resistance for playing means including a turntable, stable disk loading, and easy cost reduction. To provide a disc play V.

The multi-disc play ψ according to the present invention is configured to be movable in the tray arrangement direction with respect to a predetermined support member, and locks a movable member carrying a playing means with respect to the support member when a disc is being played. Locking means is provided, and the locking means includes at least three longitudinal sliders provided on the movable member so as to be able to reciprocate in a predetermined direction, and provided at one end of each longitudinal slider and engaged with the support member. and a locking pin for driving the slider, and a slider driving means for driving the slider, the slider driving means for synchronizing the movement of each slider at the same time, and a locking pin for moving the slider between a first position and a second position on the movable member. a relay lever that is swingably provided and that engages one of the sliders at its free end; a rocking force applying means that applies rocking force to the relay lever; position and a biasing means for biasing toward the second position.

This rocking force applying means, the synchronizing means including the intermediate lever 128, etc., the relay lever 132, and the spring member 134 constitute a slider driving means for driving the sliders 121 to 123. Further, the slider driving means, each slider 121 to 123, each locking pin 125, and a coil spring 126 (
26), the movable member 18 (composed of one movable chassis A and a movable chassis 820, shown in FIG. 6, etc.) carrying playing means including the turntable 23 etc. is used to play the disc. A locking means is configured to lock against the chassis 16 as a support member when the vehicle is in use.

Next, a disk presence/absence detection means for detecting the presence or absence of each disk in the magazine 5 will be explained.

As shown in FIG. 2(b) and FIG. 27, on the right side of the magazine 5, a predetermined area is provided on the right side of the magazine 5 in a plane parallel to the main surface of each tray 11 and 12 in the magazine and centered on the pin 137. 2 groups of 3 each can be rotated freely within the range, combined

．． 142 and 143 are arranged. The rotary levers are provided so as to overlap in the vertical direction (in the direction of arrow Z and the direction opposite thereto), and one rotary end of the levers touches the outer periphery of the disk 10 supported on each tray 11 and 12. can be engaged. Rotating levers 138, 139 and 14

7 Otosensor 146 for detecting movement of the other end of 3
is provided.

Rotating lever 138 detected by photo sensor 145
Each of the wheels 140 is formed into a substantially flat plate shape, and the rotary lever 14 is detected by a photosensor 146.
1 to 143 are provided with rising portions 141a, 142a, 143a extending upward (in the direction of arrow Z). As a result, two photosensors 145 and 146
are arranged along a plane parallel to the main plane of each tray 11 and 12. Although not shown, a biasing means is provided for biasing each of the rotary levers 138 to 143 so that one end of the rotary lever approaches the outer periphery of the disk 10.

The above-mentioned rotating levers 138 to 143 and the photosensors 145 and 146 constitute disk presence/absence detection means for detecting the presence or absence of each disk in the magazine 5. In other words, the photosensor 1 detects changes in the angular position of each rotary lever 138 to 143 due to the presence or absence of a disk.
45.146 to determine the presence or absence of a disc.

Next, the operation of the multi-disc player configured as described above will be briefly explained along the playing procedure with reference to FIGS. 28 to 32.

First, when the operating button group 6 shown in FIG. 1 is operated to specify a disc to be played, a driving voltage is supplied to the motor 45, and the moving plates 37 and 38 are moved forward (in the direction of arrow Y). Alternatively, it starts moving in the tangential direction (counter-arrow Y direction). Therefore, the stepped cams fi37d and 38d formed on the moving plates 37 and 38 and the chassis 1
6, the pin 20c movably fitted into the trapezoid is moved up and down,
A moving section 018 including a movable chassis B20 on which the pin 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 moving plate 37 back and forth,
Therefore, the vertical movement and positioning of the tray projecting member 53 will be described in detail.

The DCN signal shown in FIGS. 28 and 29 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 movable plate 37 is at its most backward movement position (forward movement limit position), that is, the home position.

As shown in FIG. 28, the photosensor 51
If a movement command is issued while the T signal is being emitted, the current address (current t) and desired address (search disc
) The moving plate 37 is moved by a distance corresponding to the difference between the two. Furthermore, if a movement command is issued while the photosensor 51 is not emitting the DCNT signal, the moving plate 37 will move forward until the DCHM 47fs signal is emitted from the detection switch 49. Move to the (Search DISC) position.

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 to the right (counter to the direction of arrow X). Second
As shown in FIG. 0, the second lever member 72 is in a locked state with the second lever member 71 by locking/releasing means comprising a movable θJ 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 clockwise, for example, as shown in J3 in FIG. Therefore, as shown in FIG. 2(b),
A tray carrying a disc to be played (for example, tray B12) protrudes from the magazine body 8, and the disc is positioned concentrically with the disc carrying surface 23a of the turntable 23 (see No. 11), that is, directly below the disc carrying surface. Move up to. 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. The slight rightward movement of the first month 71 after the cancellation is caused by the coil spring ring 75.
(see FIG. 20, etc.), and the arc-shaped portion 12n (second
The positioning of the tray is completed when the tray (see FIG.

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. In addition, the flexible anti-slip protrusion 12j formed on the tray 812, etc.
Before the tray protrudes from the magazine body 8, it is in the state shown in FIG.

The second lever member 12, which has been released from the locked state with the second lever member 71, is further driven to the right (in the opposite direction of the arrow Support 79 of the clamping mechanism engaged by 79C
(shown in Figure 10) swings upward (in the direction of arrow Z). Therefore, the disc is lifted upward and clamped to the turntable 23 (the state shown in Figure 31).

The upward movement of this disk is shown in Figure 28 (13
and is shown as a Disc load. Further, as the disk moves upward, the rotation of the intermediate lever 70 causes the disk pressing member 83 to move one inch together with the disk. 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.

Here, the roller 111 shown in FIGS. 24 and 31
The operations of the lever member 112 and the like will be described in detail.

When the tray B12 protrudes from the magazine body 8, the roller 111 rotates while contacting the main surface of the disk 10 on the tray due to the biasing force of the coil springs 115 and 116. When the tray B12 is completely ejected, the disc 10 is located directly below the turntable 23. After this, the disc is moved upward by the clamp 11 h'4 as described above, but as the disc moves upward, the disc 10 is positioned directly below the turntable 23. As the lever member 112 swings upward, the roller 111
The state of contact with the main surface of the disk is maintained. At the same time as the disk is clamped, the other lever member 113 is swung, for example, in the direction S1 in FIG. Then, the lever member 112 is also swung clockwise by a predetermined angle. As a result, the roller 11
1 separates from the main surface of the disk 10. Note that, as mentioned above, the swinging of the lever member 113 is caused by the swinging of the second lever member 7.
2 (see FIG. 10, etc.).

On the other hand, as shown in FIG. 32, the rotation of the intermediate lever 70 causes the relay lever 132 to swing counterclockwise in FIG. 32 by a predetermined angle. Relay lever 13
2 is made by rotating the intermediate lever 70 only at the initial movement, and the subsequent swinging operation is due to the biasing force of the spring member 134. Due to the swinging of the relay lever 132, the first branch portion 132b of the relay lever is connected to the slurry 1' da 122 (Q pin 122).
01. : engages and pushes the slider to the left (arrow X direction), thereby pushing the other sliders 121 and 123 (second
5) also moves. Therefore, the locking pin 125 provided at the end of each slider supports the chassis 16 as a support member.
into the locking hole 16g (shown in Figure 25) formed in the
Therefore, the entire moving member 18 including the movable chassis B20 is locked with respect to the chassis 16.

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 operations are repeated depending on the specified bending fault.

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 pin 64a, and the magazine 5 engaged with the free end of the swing lever is pushed out of the player body.

Effects of the Invention As detailed above, in the multi-disc player according to the present invention, the movable member is provided movably in the tray arrangement direction with respect to a predetermined support member (chassis 16) and carries performance means including a turntable or the like. A locking means is provided for locking (18) relative to the support member when the disc is being played.

Therefore, even if the multi-disc player receives a relatively large external force while playing a disc, the movable member will not vibrate significantly. In other words, the performance means has good vibration resistance, making it suitable for use in a vehicle, for example.

Further, in the multi-disc play V according to the present invention, the locking means includes at least three longitudinal sliders (121, 122, 123>) provided on the movable member so as to be able to reciprocate in a predetermined direction, and each of the longitudinal sliders (121, 122, 123) It has a locking pin (125) provided at one end of the slider and capable of engaging with the support member, and a slider driving means for driving the slider, and the slider driving means synchronizes the operation of each of the sliders. synchronizing means (consisting of intermediate levers 128, 129, 130, etc.); and one of each of the sliders at the free end, provided on the moving member so as to be swingable between a first position and a second position. a relay lever (132) that engages with the relay lever (122); a rocking force applying means that applies rocking force to the relay lever; and a biasing force that biases the relay lever toward the first position and the second position. and a biasing means (spring member 134).

That is, when the relay lever is moved by a predetermined angle by the rocking force applying means, the relay lever is further rocked from this rocking position by the action of the biasing means, thereby causing the relay lever to move by a predetermined angle. The slider (122) engaged with the free end of the lever moves, and each of the locking pins <125) attached to one end of each slider engages with the support member (Shi1ν-Shi16). The moving member (18
) is for the support member. The configuration is such that it is locked. At this time, the engagement force of the locking pin with the support member is only applied by the biasing means (spring member 134), but since the biasing means is composed of a spring member, this engagement force is always appropriate. It becomes a strength. Therefore, problems such as the locking pin being unable to be removed from the support member due to the excessively strong engagement force of the locking pin with the supporting member indicated by -F cannot occur, and disc loading is always performed stably. be.

Furthermore, the sliders, relay levers, etc. can be manufactured at low cost from steel plates, and the spring member serving as the biasing means is also inexpensive, making it easy to reduce costs.
