Description

TECHNICAL FIELD The present invention relates to a multi-disc player.

BACKGROUND ART A front loading disc player is of a type in which an insertion port is formed in a front panel portion of a player housing, and an information recording disc (hereinafter, simply referred to as a disc) is supplied through the insertion port and brought to a playing position. It is possible to put an object on the upper surface of the player.

Various types of front loading disc players have been developed. For example, as disclosed in Japanese Patent Laid-Open No. 61-80554, an elongated slot is formed in the front panel portion so that a disc can be inserted as an insertion port. Then, there is a slot-in system in which a disk inserted through this slot is conveyed in a direction parallel to the main surface of the disk and a direction perpendicular to the main surface and is mounted on a turntable. Further, as disclosed in Japanese Patent Laid-Open No. 62-291748, a carrier having a rectangular opening formed in the front panel portion is provided so that it can be housed in a protruding manner, and a disc is mounted on the carrier protruding outside the player housing. There is a carrier projecting and accommodating type in which the disk is mounted on the turntable by moving the carrier in two directions, that is, the horizontal direction and the vertical direction after carrying the disk. Further, as disclosed in Japanese Patent Laid-Open No. 64-52250, a magazine in which a plurality of discs are arranged and housed is removably inserted into a mounting portion in a player housing through an insertion opening of a front panel portion, A disc ejecting / conveying mechanism for sequentially selecting arbitrary discs in the magazine and moving the discs in two directions, that is, a direction parallel to the main surface of the discs and a direction perpendicular to the discs, is provided. There is also a multi-disc storage player that can play one disc continuously.

As described above, in the conventional front loading disc player, since the disc having a large area is moved in order to mount the desired disc on the turntable, a large space is provided in the player housing for moving the disc. It is necessary to provide the player, and it is difficult to downsize the player.

By the way, recently, it is desired to develop a front loading disc player that can be mounted near the driver's seat of an automobile. However, since the space occupied by the player in the vicinity of the driver's seat is extremely small, it is difficult to meet this demand by following the above configuration.

SUMMARY OF THE INVENTION [Object of the Invention] The present invention has been made in view of the above points,
The aim is to provide an extremely compact multi-disc player.

[Structure of the Invention] A multi-disc player according to the present invention includes a playing means provided in a player housing including a turntable, a pickup and a disc clamp mechanism, and a magazine mounted in the player housing for accommodating a plurality of discs.

Therefore, it comprises a movable carrier member having a swing center on one end side and movably carrying the playing means on the other end side, and a carrier member drive means for rocking the movable carrier member. The swing center is arranged near the outside of the magazine and near the corner. ing.

[Operation of the Invention] In the multi-disc player having such a structure, when a performance command is issued in a state where the disc to be played is held in the magazine, the movable supporting member is swung in the magazine to turntable. The playing means including is attached to the disc, and thereafter, the disc is clamped by the disc clamping mechanism, and the pickup is operated to start the performance.

Embodiments Hereinafter, a plurality of disc storage players as an embodiment of the present invention will be described with reference to the accompanying drawings.

The plural disc storage player has, for example, a player housing 2 as a main part, which is detachably inserted and mounted into a holding space for holding the plural disc storage player through an insertion port formed in a dashboard (not shown) of an automobile. The front portion of the player housing, that is, the front panel portion is exposed outside the holding space.

As shown in FIG. 1, the front panel 3 forming the front surface of the player housing 2 is formed with a rectangular insertion opening 3a for inserting and mounting the magazine 5 in the mounting portion inside the player housing. The insertion port 3a extends in the left-right direction. The arrow X direction is the left side and the arrow Y direction is the front side. Arrow Z indicates the upper direction. Although not shown, the front panel 3 is provided with an operation unit for operating the player for storing a plurality of discs and a display unit for displaying the operating state of the player.

As shown in FIGS. 1 to 5, the magazine 5 is composed of an upper half body 6 and a lower half body 7 which are separable from each other, and has a flat rectangular parallelepiped housing as a whole, and is arranged and housed in the housing. It has two types of substantially rectangular plate-shaped trays A11 and B12, each of which can carry the disk 9 on its main surface. The lower half body 7 is simply formed in a substantially rectangular plate shape so as to form only the bottom surface portion of the housing, and the upper half body 6 is an edge portion of the rectangular plate shape main portion so as to form the upper surface portion and the side surface portion of the housing. Is formed by integrally connecting hanging parts extending downward.

Three trays A11 and two trays B12 are provided, and these are alternately arranged. The tray A11 and the tray B12 have circular holes 11a and 12a at one corner thereof. As shown in FIG. 2, these are formed on a cylindrical member 14 projecting from the inner wall surface of the corner of the lower half body 7. The circular holes fit smoothly. Therefore, as is apparent from FIG. 3, the trays can rotate around the columnar member 14, so that the trays can be housed so as to project into the housing including the upper half body 6 and the lower half body 7. . As is particularly clear from FIGS. 6 (a) to (c) and FIGS. 7 (a) to (c),
The two types of tray A11 and tray B12 have almost the same shape as a whole except for the following points.

That is, the positions of the claw portions 11b and 12b on which the operator applies his / her fingertips when pulling out the trays from the magazine 5 are different, and these claw portions are relatively displaced in a plane parallel to the main surface of each tray. It is arranged. Due to such a configuration, when one finger, for example, the nail portion 11b of the tray A11 is put on the fingertip,
The claw portion 12b of the other tray B12 adjacent to the tray A does not interfere with the fingertip, and the tray can be easily taken in and out of the magazine 5.

Also, the ends of both trays A11 and B12, in this case,
On a virtual straight line passing through the center of the disc-carrying surface of each tray, that is, on a diagonal line connecting two diagonals of each tray formed in a rectangular plate shape or in the vicinity thereof, a separation described later Two types of held portions 11c and 11d and 12c and 12d for holding a plurality of tray holding arms, which are constituent members of the positioning means, respectively, are formed. 6 (a) and (b) and FIG. 7 (a)
As is clear from (b) and (b), one of the two types of held portions formed on each tray is the held portions 11c and 12c, which are grooves formed on the end surface of the tray. Also, FIG. 6 (a)
As shown in (c) and FIGS. 7 (a) and (c), the other held portions 11d and 12d are formed to be thinner than the other portions by slightly engraving both main surfaces of the tray. It will be done. It should be noted that these held portions 11d and 12d may be formed to have the same thickness as the other portions instead of being made thin. However, such a thin wall contributes to making the magazine 5 thinner.

As is clear from the figure, the held portions 11c and 11d formed on the tray A11 and the other tray B adjacent to the tray A11 are held.
The held parts 12c and 12d formed on the plate 12 are arranged so as to be relatively displaced in a plane parallel to the main surface of the tray. That is, the held portions 11c and 11d, and 12c and 1
The 2d's are not arranged in a straight line in the direction perpendicular to the main surface of each tray, but are displaced from each other along the main surface of the tray and dispersed. Due to this configuration, the space to be provided in the player housing 2 for swinging each tray holding arm described later for separating the trays is reduced in the direction perpendicular to the main surface of the tray, and the magazine is In this direction, the size of the player 5, that is, the thickness of the player 5, and the player as a whole can be easily reduced.

As shown in FIGS. 6 (a) to 7 (c), each of the trays A11 and B12 has the above-mentioned held portions.
Notches 11f, 11g, 12f and 12g are formed near 11c, 11d, 12c and 12d, respectively. As will be described later, these notches are for avoiding interference between each tray holding arm which is a constituent member of the separating / positioning means (described later) and the tray adjacent to the tray held.

As is clear from FIGS. 6 (a) to 7 (c), circular recesses 11h and 12h for accommodating and positioning the disks 9 are provided on the main surfaces of the trays A11 and B12.
And openings 11i and 12i through which a clamper described later can be inserted. Further, as shown in FIGS. 4 and 5, the lower half body 7 forming a part of the housing of the magazine 5
Similarly to the trays described above, held portions 7a and 7b that are held by the tray holding arm (described later) of the separating / positioning means are formed at the end portions of the above as thin-walled portions that are thinner than other portions. ing. It should be noted that these held portions 7a and 7b may be formed to have the same thickness as the other portions instead of being made thin.

As shown in FIG. 2, at the corner portion of the inner wall surface of the lower half body 7 of the magazine 5, two cylindrical members 16 and 17 similar to the above-mentioned cylindrical member 14 are provided in a protruding manner. Each tray A11 and tray B12 is also movable in the axial direction of the columnar member 14 that rotatably supports them, and the columnar member 14 not only acts as a shaft supporting member that pivotally supports each tray, but also It also acts as a guide member that guides the tray so that the positions thereof are two-dimensionally aligned. The number of parts is reduced by one as compared with the structure in which one cylindrical member 14 is provided and two members which individually perform the respective operations by providing the two operations are provided.

As described above, each tray A11 and tray B12 is projected and stored in the magazine 5 by rotating around the cylindrical member 14. The tray protruding / storing operation is not limited to the rotation as described above, and a configuration in which the tray is linearly reciprocated is conceivable. However, by adopting such a rotation configuration, the movement of the tray is always performed smoothly, The operability is good when the operator inserts or removes the tray into or from the magazine without loading or replacing the disc.

Here, the upper half 6 that constitutes the housing of the magazine 5
A lock mechanism for fixing the lower half body 7 to each other will be described.

As shown in FIGS. 2 to 5, on the inner wall surface of the upper half body 6, a disk-shaped and annularly formed movable locking member 19 is rotatably attached along its main surface. More specifically, as shown in FIGS. 2, 4, and 5, on the inner wall surface of the upper half body 6, there is provided a support member 20 having a substantially L-shaped cross section perpendicular to the center of the ring. The upper end surface is fixed by an adhesive or the like, and the movable locking member 19 is arranged so as to be slidably held at its inner peripheral portion by the lower side portion of the supporting member 20 and the upper half body 6. ing. On the outer peripheral portion of the movable locking member 19, three projecting portions 19a to 19c are provided so as to project,
Semicircular cutouts 19d to 19f are formed at the tips of the respective overhanging portions, and serve as locked portions formed on the outer peripheral surfaces of the tips of the three cylindrical members 14, 16 and 17 described above. Annular groove 14a, 16a
The notches 19d to 19f can be smoothly fitted into the cutouts 17a and 17a. FIG. 8 shows a perspective view of, for example, the cylindrical member 14 and the overhanging portion 19a that engages with it. In addition, other 2
The same applies to the relationship between the columnar members 16 and 17 of the book and the projecting portions 19b and 19c. That is, for each of the annular grooves 14a, 16a and 17a of the three columnar members 14, 16 and 17 fixedly provided in the lower half body 7, each of the movable locking members 19 provided in the upper half body 6 is arranged. Notch 19
By fitting d to 19f, the upper half body 6 and the lower half body 7 are fixed to each other, and by releasing the fitted state, the two half bodies can be separated. The position of the movable locking member 19 in a state where each notch 19d to 19f is fitted into each annular groove 14a, 16a and 17a is referred to as a locking position, and the position of the movable locking member 19 where the fitting is released. Is called a non-locking position.

As shown in FIG. 3, a cylindrical member on the lower half 7
In the vicinity of 17, the notch 19d of each overhang 19a to 19c is formed by engaging one overhang 19c of the movable locking member 19.
To 19f are annular grooves 14a, 16a of the cylindrical members 14, 16 and 17, respectively.
And the biasing lever 21 for biasing the movable locking member 19 in the direction of fitting with 17a (direction of arrow G) is the support pin 21a.

And constitute a lock mechanism for fixing the upper half body 6 and the lower half body 7 to each other.

By providing such a lock mechanism, when the operator handles the magazine 5 for loading or exchanging the disc into or from the magazine 5, the lock mechanism is operated to fix the upper half body 6 and the lower half body 7 to each other. By doing so, it is possible to prevent the upper half body 6, the lower half body 7, and the trays accommodated therein from being inadvertently separated.

As described above, since the lock mechanism is configured to fix the upper half body 6 and the lower half body 7 at three points at the same time, the upper half body 6 and the lower half body 7 are accurately joined without distortion. Sent.
Further, since the movable locking member 19 is formed in a substantially disc shape and rotates along the main surface thereof, the space to be provided in the magazine 5 for the operation of the movable locking member 19 becomes small and the magazine 5 In itself, it contributes to downsizing of the player as a whole. However, the shape and movement of the movable locking member 19 are not limited to such a configuration, and various other forms such as a swingable arm shape or a linear reciprocating lever shape may be used. It goes without saying that it is applicable.

In addition, as described above, the tray 3 supports the trays and guides them.
Since the columnar members 14, 16 and 17 of the book are also used as members for fixing the upper half body 6 and the lower half body 7 to each other in this way, the number of parts is kept small.

Next, description will be made of a performance means transporting mechanism for moving the performance means including the turntable, the pickup and the disk clamp mechanism and mounting the performance means on the disk to be played in the magazine 5 in which the performance means is mounted.

As shown in FIGS. 9 to 12, the magazine 5 is inserted and mounted in the mounting portion in the player housing 2. The upper half body 6 and the lower half body 7 which compose the magazine 5, and the end portions and the side end portions of the tray A11 and the tray B12, respectively, in the magazine insertion direction are aligned in a straight line in the arrangement direction of the respective trays. Notch 6 as if forming two grooves as
a, 6b, 7d, 11j, 11k, 12j and 12k are formed. In addition,

As shown in FIGS. 9 and 10, in the player housing 2, two guide shafts 24 and 25 are vertically arranged so as to fit into the two long grooves formed by these notches. The guide shaft 25 is arranged to extend and is fixed to the player housing 2. These guide shafts 24 and 25 are in sliding contact with the respective trays A11 and B12 and the lower half body 7 which are separated from each other as will be described later, and guide them in the separating direction. As shown in a perspective view of one guide shaft 24 in FIG. 13, flanges 24a and 25a are formed near the upper ends of both guide shafts 24 and 25, and form the upper half of the housing of the magazine 5. Notch 6a of upper half 6
By fitting the guide shafts 6 and 6b to the upper end portions of the guide shafts 24 and 25, the upper half body 6 is supported by the collar portions 24a and 25a, and the downward movement of the upper half body 6 is restricted. In addition,
As described above, one guide shaft 25 is fixed to the player housing 2, while the other guide shaft 24 is swingably provided to the player housing 2 via the support pin 26a. Lever member 2
It is projectingly provided on the free end portion of 6, and is biased by the spring member 27 toward the magazine 5. Therefore, the guide shaft 24 is retracted by the lever member 26 swinging clockwise in FIG. 9 while being pushed by the insertion of the magazine 5 into the player housing 2, and the guide shaft 24 is retracted. The insertion is not blocked, and the lever member 26 is returned by the urging force of the spring member 27 upon completion of insertion of the magazine, so that the lever member 26 is fitted into each notch of the magazine 5.

Further, as shown in FIGS. 3 and 9, the disk-shaped movable locking member 19 which fixes the upper half body 6 and the lower half body 7 of the magazine 5 to each other has three protruding portions thereof. 19a to 19c
One of the overhanging portions 19a is integrally formed with another overhanging portion 19g, and as the magazine 5 is mounted in the player housing 2 as described above, the above guide shaft is formed. 25 is in a state of pushing the overhanging portion 19g. As a result, the movable locking member 19 is rotated in the counterclockwise direction in the figure, and the respective projecting portions 19a to 19c of the movable locking member 19 are locked by the three cylindrical members 14, 16 and When the upper half 6 and the lower half 7 are separated from each other, the fixed state between the upper half 6 and the lower half 7 is released, and the two can be separated.

The performance means transport mechanism described below has an upper half 6 of the magazine 5 which can be separated as described above in response to a performance command.

A driving force applying means for applying a driving force to 0 is configured. The driving force applying means and the cam members 29 and 30 constitute a holding arm driving means for swinging the tray holding arms 43 to 48 and 73 to 78, that is, a holding member driving means. Further, the holding arm drive means and the tray holding arms separate the upper half 6 and the lower half 7 of the magazine 5 from each other, and the tray holding the desired disc among the trays accommodated therein is selected. Separation and positioning means is provided which selects and positions this by separating it from other trays in a direction perpendicular to the main surface of the tray. The separating / positioning means is also referred to as a disk holding means. That is, the disc to be played is separated from other trays by the separating and positioning means together with the tray carrying the disc and is positioned and held at a predetermined position. The disc at this position is turned as described later. The playing means including the table is mounted in close proximity to start playing.

Here, the above-mentioned separation positioning means will be described in more detail.

First, as described above, the separating / positioning means has two sets of tray holding arms of six each driven by the two cam members 29 and 30, and each tray of the magazine 5 is driven by the both tray holding arms. The held portions 11c, 11d, 12c and 12d formed on the virtual straight line passing through the center of the disk carrying surface along the disk carrying surface or at the ends near the virtual straight line are held. In other words, each tray formed in the shape of a rectangular plate is held by the tray holding arm group on or near the diagonal line connecting the two diagonal corners. On the other hand, the magazine 5 and the player housing 2 surrounding the magazine 5 are both formed in a rectangular parallelepiped shape. In the configuration in which the rectangular parallelepiped magazine 5 is surrounded by the rectangular parallelepiped player housing 2 as described above, as described above, two sets of trays are held near the diagonals of the trays, and thus the two diagonals of the entire magazine 5. By arranging the arm groups separately, a relatively large space can be obtained in a portion located in the middle of both tray holding arm groups, that is, in the inner corner of the player housing 2. Therefore, it is possible to efficiently dispose the holding arm drive means including the above-mentioned cam members 29 and 30 and the motor 32 in this space.

Further, as described above, two sets of tray holding arm groups each consisting of six tray holding arms are provided, and these tray holding arm groups hold each of the trays at two positions in the vicinity of the diagonal line thereof and carry the discs on the trays. Although it is configured to separate in the direction perpendicular to the plane, each tray has two guide shafts 24 and 25 as described above.
Since they are guided by each other without being displaced from each other, it is not necessary to hold them in two places like this, and one of the two holding arm groups of the two holding arm groups, for example, tray holding arms 43 to 48 It is also possible to hold the tray only at one place and apply the moving force.
Therefore, the remaining group of tray holding arms, that is, the tray holding arms 73 to 78, cooperates with the group of holding arms of the other group to hold each tray and move the trays in parallel so that the trays do not tilt. It will act as a tray tilt regulation means. The tray holding arms 43 to 48 are referred to as a first tray holding member, while the tray holding arms 73 to 78 of the other set are referred to as a second tray holding member.

By providing such tray tilt restricting means, the tray can always be moved in parallel without tilting, so that the disk on the tray does not shift due to tilting of the tray, and the playing means including the turntable described later is mounted on the disk. Is always reliable and smooth.

Incidentally, as a driving force applying means for applying a driving force to each tray holding arm 73 to 78 as the above-mentioned tray tilt restricting means, to each tray holding arm 43 to 48 which exclusively controls the separating operation of each tray. Since the motor 32 for giving the driving force is also used, it is not necessary to specially provide the driving force giving means dedicated to the tray tilt regulating means, and the reduction of the driving source is achieved.

Here, the configuration of each tray holding arm group will be described in more detail. As shown in FIG. 9 and FIG. 11, the six tray holding arms 43 to 48, which is one tray holding arm group disposed behind the magazine 5, are arranged along two virtual planes which are alternately different from each other. Are arranged so as to swing. That is, six tray holding arms are alternately arranged in two small sets, in this case, the tray holding arms 43 and 45.
And 47 as one small set, the remaining three tray holding arms
44, 46, and 48 are divided into another sub-set, and the virtual planes along which the tray-holding arm groups of both sub-sets should move are offset from each other in the horizontal plane. Due to this structure, if these two virtual surfaces are made to overlap each other in the horizontal direction as shown in the figure, all tray holding arms will be
Compared with the configuration in which 43 to 48 are moved along one common virtual plane, the projected area of the virtual plane required for moving each tray is halved, which facilitates downsizing of the player as a whole. Of.

Further, as shown in FIG. 9, the tray holding arms 43, 45 and 47 as one small set and the tray holding arms 44, 46 which are the other small set are arranged so as to be offset from each other in the horizontal plane as described above.

As is clear from FIG. 15, a cylindrical female screw 123 is screwed on a male screw 96 that rotatably and slidably fits on the support shaft 95 and carries the movable carrying member 98. A gear 123a is integrally formed at the lower end of the female screw 123, and the torque from the motor 121 is sequentially passed through the gears 124 and 125a, the worm wheel 125b, the worm 126, and the gears 127 and 128. It is transmitted to the internal thread 123.

On the other hand, a cylindrical member 130 is rotatably fitted on the female screw 123, and a cylindrical pin 130a is projectingly provided on the upper end of the cylindrical member and formed on the movable carrying member 98. The pin 130a is inserted through the circular opening 98f with a predetermined gap. A gear 130b is integrally formed at the lower end portion of the cylindrical member 130, and the gear 132, the face gear 133, the worm 134, the worm wheel 135a, the gear 135b, and the gears 136 and 137 are sequentially solved, and the gear from the motor 122 is removed. Torque this gear

A pin 137a protruding from the upper main surface of the lower gear 137 is slidably fitted. Further, as shown in FIG. 9, the support shaft 95 for rotatably supporting the movable supporting member 98 is moved to the above-mentioned non-insertion position with respect to the movable supporting member, that is, the position shown by the chain double-dashed line in FIG. A spring member 140 as a biasing force applying means for applying a biasing force toward it is fitted.

The above-mentioned motors 121 and 122 and gears 123a, 124 and 125

The gears 135b, 136 and 137, and the pin 137a constitute torque applying means for selectively applying torque to each of the female screw 123 and the cylindrical member 130.
Further, the torque applying means, the female screw 123, and the cylindrical member 1
The 30 and the above-mentioned male screw 96 constitute a carrying member driving means for rocking the movable carrying member 98 around the supporting shaft 95 and moving the movable carrying member 98 along the supporting shaft 95. Further, the carrying member driving means and the movable carrying member
98, a support shaft 95, and the above-mentioned separate positioning means,
The spring member 140 that applies a biasing force to the movable supporting member 98 constitutes a playing means transport mechanism that moves the above-mentioned playing means such as the turntable 100 and mounts it on the disk to be played.

As described above, the movable supporting member 98 is configured to swing. However, the movement of the movable supporting member 98 is not limited to such swinging, and various other things such as parallel movement may be considered. To be However, by adopting such a swing structure, the operation of the movable carrying member 98 is always reliably and smoothly performed.

Further, as described above, the movable carrying member 98 is swingably attached to the support shaft 95 so as to swing between the insertion position where the movable carrier member 98 is inserted between the trays of the magazine 5 and the non-insertion position, and is separated from other trays. Since the movable carrying member 98 is movable in the axial direction of the support shaft 95 so as to bring the playing means to a position corresponding to the played tray, downsizing of the player as a whole is achieved. What is needed is, as another structure for making the movable supporting member 98 movable in two different directions as described above, for example, the movable supporting member.
It is conceivable that the support shaft 95 is mounted on the support shaft 95 so as to swing only, a predetermined moving member that is movable in the tray separating direction is provided, and the support shaft 95 is mounted on this moving member. However, in such a virtual configuration, the moving member and a guide mechanism for movably guiding the moving member in the tray separation direction are required as compared with the configuration on the implementation side, and the player as a whole increases in number as the number of parts increases. This leads to a larger size.

By the way, as is apparent from FIG. 9, the disposition position of the support shaft 95, which is the swing center of the movable supporting member 98, is the holding position of each tray by the tray holding arms 73 to 78, which is a disc holding means. , Located in front of the held portions 11c and 12c of each tray, and closer to the insertion opening 3a for loading the magazine 5 formed in the player housing 2 than the held portions, that is, the magazine. It is set on the outer side of No. 5 near the corner. By providing the swing center of the movable carrying member 98 at such a position, a relatively large space is formed in the central portion and the inner part of the player housing 2, and the above-mentioned carrying member driving means for operating the movable carrying member 98 and This space can be used as a space occupied by another mechanism, and the degree of freedom in selecting the setting position of the mechanism inside the player is increased.

Here, a motor for swinging the movable carrying member 98
A structure for operating the above-mentioned disc clamp mechanism with the power generated by 122 will be described.

As shown in FIG. 9, FIG. 16 and FIG. 17, an intermediate lever 142 is provided with a screw 142a (16th embodiment) on the lower surface of the base end portion of the movable carrying member 98.
(Shown in the figure), the central part of the horizontal plane is swingably mounted. A cam portion 136b is integrally formed on the upper surface of the gear 136, which is a component of the power transmission mechanism that transmits the power from the motor 122 to the movable supporting member 98, and is formed at the swinging end of the intermediate lever 142. The cam surface of the cam portion can be slidably contacted with the hanging portion 142b (reference numeral is shown only in FIG. 16). As shown in Figure 16,
A hanging portion 142b is also formed at the other end of the swing of the intermediate lever 142, and a protrusion 142c protruding from the hanging portion 142b is a clamper arm 115 that is a component of the disc clamp mechanism.
It is brought into contact with the drooping portion 115a formed on the. That is, the cam portion 136b integrated with the gear 136 is rotated by the power applied from the motor 122, and the cam surface of the cam portion abuts against one hanging portion of the intermediate lever 142 and presses it. Screw 1 with which the intermediate lever 142 pivots
The protrusion 142c formed on the other end of the swing of the intermediate lever 142 swings around the center of the clamp lever 42a.
It is configured so that the disk clamp is made by pressing.

FIG. 18 shows the configuration of the control unit that controls the operation of each internal mechanism of the multiple disc storage player having the above-described configuration.
The reference numeral 50 cooperates with the RAM 153 according to each signal from the keyboard 152 including the photosensors 84 and 112, the detection switch 111, and a switch group (not shown) in accordance with a control program stored in advance in the ROM 151. , Motors 32, 108, 1
21 and 122, turntable 100 and pickup 15
Issue a command to 5.

An example of the control program will be described with reference to the flowcharts shown in FIGS. 19 to 21 and the operation explanatory diagrams of FIGS. 22 to 27.

First, when a keyboard 152 shown in FIG. 18 is operated by an operator to issue a performance command for causing a desired disc to be played, and a music piece is designated, the plural disc storage player is operated from FIG. 19 to FIG. It operates according to the flowchart shown in FIG.

As shown in FIG. 19, when a performance command is issued and a music piece is designated (step S1), the control unit firstly does not show that the magazine 5 is mounted in the player housing 2. It is confirmed by the detection signal emitted by the detection means (step S2). If the magazine 5 is mounted, the internal mechanisms are operated by executing the first loading subroutine (step S3) shown in FIGS. 19 and 20. In executing the first loading subroutine, the magazine 5 is only inserted and mounted in the player housing 2, and the lower half body 7 and the upper half body 6 of the magazine 5 are not yet separated.

A movable locking member that fixes the upper half 6 and the lower half 7 of the magazine 5 to each other by inserting and mounting the magazine 5 into the player housing 2 by the operator.
The guide shaft 25 shown in FIG.
Will be pushed by the reaction force of this mounting force. As a result, the movable locking member 19 is rotated counterclockwise in FIGS. 2 and 9, and the three overhanging members 19a to 19c of the movable locking member 19 are locked by the three columnar members. 14, 16
When the upper half 6 and the lower half 7 are separated from each other, the fixed state is released, and the two can be separated. In this state, the movable carrying member 98 on which the playing means including the turntable 100 is mounted is in the non-insertion position shown by the chain double-dashed line in FIG.

Further, when the magazine 5 is mounted in the player housing 2, the tray holding arms 43 to 48 and 73 to 78 hold the trays and the held portions of the lower half body 7, respectively.

As shown in FIG. 20, when the above command is issued, the control section first causes the motor 32 to rotate normally (step S4) to rotate the two cam members 29 and 30 by the angle θ, for example, 30 °.
Install each tray holding arm 43 to 48 and 73 to 78 to the 11th
It is swung from the state shown in FIGS. 12 and 13 to the state shown in FIG. As a result, the lower half 7 of the magazine 5 is moved downward and separated from the upper half 6. Also,
As shown in FIG. 22, at the same time when the lower half body 7 and the upper half body 6 are separated, the bottom tray A11 of the five trays accommodated in the magazine 5 is separated from the other trays and turned. It is brought to a position corresponding to the playing means including the table 100.

When the disc containing the designated music is carried on the third tray A11 from the bottom among the arranged five trays, the motor 32 is further rotated in the normal direction (step S5), and both cams are rotated. The members 29 and 30 are further forwardly rotated by 60 ° synchronously, the state shown in FIG. 22 is changed to the state shown in FIG. 24 through the state shown in FIG. 23, and the tray A11 carrying the desired disc is separated from the other trays. To be done. Further, with the tray separating operation, the motor 121 is rotated in the normal direction (step S5), and the movable carrying member 98 carrying the playing means is moved upward from the lowermost position by a distance corresponding to the thickness of two trays. The tray 11 is moved and positioned at a position corresponding to the tray 11 separated from the other trays. The rotation angles of the cam members 29 and 30 and the rising distance of the movable carrier member 98 are determined by the number of slits 83a and 113a of the address plates 83 and 113 detected by the two photo sensors 84 and 112, respectively. The control unit counts with the counter provided and detects based on this count value. The above operation is performed while comparing the address of the tray currently located corresponding to the playing means, that is, the address of the current disk with the address of the search disk which is the disk being searched.

If the address of the current disc matches the address of the search disc (step S6), the motor 32 and the motor 121
Is stopped (step S7). Next, the motor 122 is rotated in the normal direction (step S8), and the movable carrying member 98 having the playing means mounted on its free end is directed from the non-insertion position shown by the two-dot chain line in FIG. 9 to the insertion position shown by the solid line. Then, the turntable 100 is mounted on the disc to be played by activating the disc clamp mechanism by operating the disc clamp mechanism. This operation will be described in more detail.

As described above, the output of the motor 122 for swinging the movable carrying member 98 is the gear 132, the face gear 133, the worm 134, the worm wheel 135a, the gears 135b and 136, and the pin.
137a, gears 137 and 130b, cylindrical member 130 and pin 130a
Are sequentially applied to the movable supporting member 98. Motor 122
Before the normal rotation starts, the arcuate groove 136a formed on the lower main surface of the gear 136 and the pin 137a planted on the upper main surface of the gear 137 to slidably fit into the groove are The positional relationship is as shown in Fig. 17. When the motor 122 starts forward rotation in this state, the movable carrying member 98 is moved toward the above insertion position (the swinging position shown by the solid line in FIG. 9) by the spring member 140 attached to the support shaft 95 pivotally supporting the movable carrying member 98. Being energized,
It is swung by the biasing force of this spring member 140. Therefore, the two gears 136 and 137 described above rotate synchronously while maintaining the relative positional relationship between the arcuate groove 136a and the pin 137a provided therein in the state shown in FIG. That is, the swinging of the movable carrying member 98 by the biasing force of the spring member 140 is in a state where the rotation of the motor 122 allows the swinging. Thus, when the movable carrying member 98 swings to the insertion position shown by the solid line in FIG. 9, the edge of the movable carrying member 98 contacts the cylindrical stopper 158, as shown in FIG.
The movable carrying member 98 is positioned at the insertion position. If the two gears 136 and 137 described above are formed integrally with each other, when this state is reached, the power transmission system including both gears is prevented from further operation. However, as described above, both gears 136 and 137 are relatively rotatable within the range in which the pin 137a slides in the arcuate groove 136a.

The motor 122 continues to rotate forward even after the positioning of the movable supporting member 98, whereby the gear 136 is rotated with respect to the other fixed gear 137. As described above, since the cam portion 136b is integrally formed on the upper main surface of the gear 136, the cam portion 136b slides on the intermediate lever 142 as shown in FIG. 27 as the gear 136 rotates. And rock it. As a result, the hanging part 115a of the clamper arm 115 shown in FIG. 16 is pushed by the protrusion 142c of the intermediate lever 142, and the clamper arm swings from the non-clamp position shown by the chain double-dashed line to the clamp position shown by the solid line (arrow). H direction), the pressing member 117, that is, the clamper pushes up the disk 9 and separates it from the tray, and the turntable 100
Clamp against. The rotation of the cam portion 136b is performed after the movable carrying member 98 reaches the above insertion position, whereby the maximum diameter portion of the cam portion 136b and the intermediate lever 14b.
The two are prevented from interfering with each other. Further, if this clamping operation is performed while rotating the turntable 100, the number of clamping errors is reduced.

After the above operation, a certain period of time is waited (shown in step S9 in FIG. 20), whereby the control unit determines that the swing of the movable supporting member 98 and the operation of the disc clamp mechanism are completed, and the motor 122 Stop (step S1
0). After that, the servo driving means (not shown) of the objective lens 105 included in the pickup is operated, and the motor 108 is rotated in the normal direction (step S11) to start the movement of the carriage 103 including the pickup to perform the performance. Start.

When it is confirmed that the performance of the first disc is completed (step S12), the control unit stops the forward rotation of the carriage driving motor 108 and the operation of the pickup, and immediately reverses the motor 108 (step S12). S13).
By the reverse rotation of the motor 108, the carriage 103 having the pickup mounted thereon is brought closest to the turntable 100 mounted on the swinging end of the movable carrying member 98. When the carriage 103 comes closest to the turntable 100, the protrusion formed on the carriage 103 causes the detection switch 111 shown in FIG.
The detection switch is operated by engaging with the actuator 111a. The control unit recognizes that the carriage 103 is closest to the turntable 100 based on the detection signal issued from the detection switch 111 (step S14), and accordingly stops the motor 108 to stop the carriage 103. (Step S15).

After the above operation, the motor 122 is rotated in the reverse direction (step S16), the disc clamp is released, and the movable carrying member 98 is moved from the insertion position shown by the solid line in FIG. 9 to the non-insertion position shown by the two-dot chain line. Rock it to. The operation of releasing the disc clamp and the movable supporting member
The returning operation of 98 is performed by following the reverse process of the above-mentioned disk clamping operation and swinging operation of the movable carrying member 98 to the insertion position, and therefore will not be described in detail.

As shown in FIG. 9, when the movable carrying member 98 returns to the non-insertion position, the photosensor 112 provided on the swing groove portion of each movable carrying member can detect the address plate 113 to be detected. Reach the position and detect this. For example, the control unit recognizes that the return operation of the movable supporting member 98 is completed based on the detection signal emitted from the photo sensor 112 (step S17), and stops the motor 122 to stop the movable supporting member 98 ( Step S18).

By the way, as is clear from the above description, in the multi-disk storage player, prior to the returning operation to the non-insertion position of the movable carrying member 98, that is, the non-opposing position to the disk being played, after the performance of the disk is completed,
The carriage 103 on the movable supporting member 98 is the turntable 100.
Is closest to.

With such a configuration, downsizing of the player is achieved. What is important is that the player housing 2 is usually formed in a rectangular parallelepiped shape as shown in the embodiment, and since the disc accommodated therein is circular, relatively large spaces are formed at the four corners inside the player housing 2. Therefore, when the longitudinal movable carrying member 98 is in the non-opposing position, the movable carrying member is arranged so as to be close to and along the inner wall surface of the player housing 2, and the end of the movable carrying member 98 is arranged. The part is inevitably accommodated in any of the four corner spaces. Therefore, if the carriage 103 is moved to the end portion of the movable supporting member 98 after the performance as described above and then the movable supporting member is returned to the non-opposing position, the space at this corner is the carriage 103 during non-performance. Is effectively used as a housing space for the player, the space utilization efficiency inside the player housing 2 is improved, and the player can be easily downsized.

By the series of operations described above, the performance of one disc is completed.

As shown in FIG. 19, after performing the above series of operations, the control unit confirms whether or not there are more designated disks (step S20). If the designated disks are two or more, The second loading subroutine (step S21) shown in FIGS. 19 and 21 is executed to activate each internal mechanism.

In the second loading subroutine, the control unit first confirms whether the second disc to be played is located above or below the disc that has finished playing first (step S22). Then, when the tray carrying the second designated disk is the tray A11 at the uppermost position among the five arranged trays, the control unit causes the motor 32 to rotate normally (step S23) to 2 The two cam members 29 and 30 are further rotated by 60 ° in the forward direction to change the state shown in FIG. 24 from the state shown in FIG. 25 to the state shown in FIG. 26, whereby the uppermost tray A11 is separated from the other trays. Further, in accordance with this tray separating operation, the motor 121 is rotated in the normal direction (step S23), and the movable carrying member 98 carrying the playing means is
It is raised by a distance corresponding to the thickness of two trays from the position determined in the above-mentioned first loading subroutine, and is positioned at a position corresponding to the lowermost tray A11 separated from other trays as described above.

On the other hand, when the second disc to be played is carried on, for example, the second tray from the top (fourth from the bottom) of the trays arranged in five, B12, control is performed. Section causes the motor 32 to rotate in the reverse direction (step S24) to rotate the two cam members 29 and 30 in the reverse direction.
In the state shown in the figure, the second tray B12 from the top is separated from the other trays. Further, in accordance with this tray separating operation, the motor 121 is rotated in the reverse direction (step S24), and the movable carrying member 98 is lowered from the position positioned in the above-mentioned first loading subroutine by a distance corresponding to the thickness of one tray. Second, the second tray B12 from above
Position the playing means at a position corresponding to.

By the above operation, when the address of the current disc coincides with the address of the second disc to be played as the search disc (step S25), the motor 32 and the motor 121 are stopped (step S26). First
Steps S8 to S1 in the loading subroutine
Based on steps S27 to S37 similar to step 8, each mechanism is operated to play the second disc.

Thereafter, as shown in FIG. 19, it is checked whether or not there is an unplayed disc after the third disc (step S40), and if three or more discs are designated, they are played according to the second loading subroutine described above. If all the performances of the specified disc have been completed, all the mechanisms are put into the performance standby state or the operation is stopped.

As is clear from FIGS. 22 to 26, among the respective tray holding arms 43 to 48 and 73 to 78, about the free end portion of the tray holding arm for holding the tray separated from the other tray group. Half of it is designed to be parallel to the tray it holds. For example, in FIG. 25, the second tray B1 from the top separated from other trays
The tray holding arm 44 holding 2 has approximately half of its free end parallel to the held tray B12. With such a configuration, the playing means including the turntable 100 and the movable carrying member 98 mounted with the playing table can always be smoothly inserted between the trays without interfering with each tray holding arm, and the playing means is securely attached to the disc. It is done smoothly.

As described above in detail, in the multi-disc player according to the present invention, the playing means including the turntable, the pickup and the disc clamp mechanism is provided for the disc held by the magazine mounted in the player housing. The movable carrying member carried is swung in parallel with the recording surface of the disk, and the playing means is mounted.

Due to such a structure, the space to be provided in the player housing for mounting the playing means on the disc to be played only allows the swinging of the movable supporting member having a considerably smaller area than the disc. Becomes small,
The player as a whole can be reduced in size, and can be used by being housed in a space formed on a dashboard of an automobile, for example, for mounting on a vehicle.

Further, in the multi-disc player according to the present invention, the swing center of the movable carrying member is arranged near the outer side of the magazine and near the corner thereof. By providing the swing center of the movable carrying member at such a position, a relatively large space is formed in the central portion and the inner portion of the player housing, and the carrying member driving means for moving the movable carrying member and other mechanisms are formed. This space can be used as an occupied space, the degree of freedom in selecting the installation position of the mechanism inside the player is increased, and the player can be further miniaturized.
