Abstract

PURPOSE:To reduce the projecting surface of a surface required for moving trays by half and to miniaturize a player by alternately dividing plural tray holding members into two groups and shifting surfaces along which the holding members in the respective groups are moved. CONSTITUTION:Six tray holding arms 43-48 in one tray holding arm group arranged at the back of a magazine 5 are arranged while being shifted so as to be alternately rocked along two mutually various surfaces. Namely, the arms 43, 45 and 47 are defined as one small group and remaining arms 44, 46 and 48 are separated as the other small group. Then, the virtual surfaces, along which the arms in these both small groups in to be moved, are mutually shifted on a horizontal surface. Thus, by setting the two virtual surfaces so as to be mutually overlapped horizontally, the projecting areas of the virtual surfaces required for moving the trays are reduced by half and the player can be miniaturized as a whole.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a disc player, and particularly to a disc player that can store a plurality of information recording discs (hereinafter simply referred to as discs) and that can sequentially select any one of the stored discs. The present invention relates to a multi-disc storage player capable of continuous performance.

BACKGROUND ART A multi-disc storage player is disclosed in, for example, Japanese Patent Application Laid-Open No. 64-522.
It is known from Japanese Patent Application No. 50, and is capable of arranging and storing a performance means including a turntable and a pickup, and a plurality of discs in order in a direction perpendicular to the disc supporting surface of the turntable, and is detachable from a mounting part in a player housing. The apparatus includes a magazine that is inserted into the magazine, and a disk ejecting and conveying mechanism that sequentially selects arbitrary disks in the magazine and conveys them onto the turntable, and conversely returns them from the turntable into the magazine.

In such a multi-disk storage player, when a selected disk is conveyed from the magazine onto the turntable, each disk in the magazine is conveyed in a direction parallel to the disk carrying surface of the turntable and in a direction perpendicular to the said direction, that is, each disk in the magazine. The disks are moved in two directions including the arrangement direction of the disks, and the above-mentioned disk ejecting and transporting mechanism does this.

Specifically, either the playing means including a turntable or the like and the magazine are supported on a predetermined movable supporting member, and this is reciprocated in the arrangement direction of the respective disks by a predetermined driving means. Instead, the disks are moved in the arrangement direction. Further, regarding the movement of the disk in the direction parallel to the disk supporting surface of the turntable, the following configuration is adopted.

As shown in FIGS. 28 and 29, the magazine is housed in a housing 251 which is a rectangular parallelepiped magazine body as a whole.
and support shafts 2 arranged in the housing in a direction perpendicular to the disk supporting surface of the turntable (in the direction of arrow Z and the opposite direction) and extending in the arrangement direction.
52, each of which can support a disk 253 on its main surface, and which can protrude from the housing along each main surface and can be housed therein. That is, by simply protruding the trays 254 each carrying a disk 253 from the housing 251, the disks 253 can be conveyed in one direction (disk conveyance in a direction parallel to the disk supporting surface of the turntable).

On the other hand, a dogleg-shaped tray pushing member 256 is rotatably provided on the side of the magazine to engage with each tray 254 one by one and push the tray out of the housing 251. Further, a sliding member 257 is provided in the vicinity of the magazine so as to linearly reciprocate, and its end 257a in the rhythmic direction engages with the tray pushing member 256. The tray pushing member 256 is moved by applying a rotational moment to the tray pushing member 256, causing it to rotate.

Note that, as shown in FIGS. 29 and 30, two pins 258a are provided protruding from the tray push-out member 256.
The tray pushing member 256 is guided by this pin 256a slidably engaging two arcuate guide grooves 258a and 258b formed in the movable supporting member (not shown) on which the playing means is mounted. and rotate.

That is, by reciprocating the movable supporting member carrying performance means including a turntable, a pickup, etc. in the arrangement direction of each tray 254 (in the direction of arrow Z and the opposite direction), the trays between each tray 254 and the turntable are moved. A configuration in which the disk 253 on this tray is positioned on the turntable by relative movement and positioning in the arrangement direction, and by rotationally driving the tray pushing member 25G described above, a desired tray 254 is pushed and projected out of the magazine. This is the result.

As mentioned above, the conventional multi-disc storage player has a structure in which, in order to mount a desired disc in the magazine onto the turntable, the disc is projected out of the magazine along the main surface along with the tray supporting the disc. However, it was necessary to provide a large space within the player housing for the movement of the disc and tray, making it difficult to downsize the player.

Incidentally, there has recently been a desire to develop a multi-disc storage player that can be installed near the driver's seat of an automobile. However, since the space allowed for the player to occupy near 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 two points mentioned above,
The purpose is to provide a multi-disc storage player that is extremely small and suitable for use in a vehicle.

[Structure of the Invention] A multi-disc storage 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 performance means installed in the player housing that cannot accommodate a plurality of discs. The magazine includes a magazine that is detachably attached to the disc, and a playing means conveying mechanism that moves the playing means and attaches it to the disc to be played. A housing consisting of a body;
The playing means comprises a plurality of plate-shaped trays which are arranged and accommodated in the housing, each of which can support an information recording disk on its main surface, and which can be protruded from the housing along each main surface and can be housed therein. The transport mechanism separates the lower half body and the lower half body, selects and holds a tray carrying a desired disk from among the trays, and transfers the tray to the other tray in a direction perpendicular to the main surface. separation positioning means for separating and positioning the trays; and a separation positioning means that is movable in the separation direction between an insertion position where the trays can be inserted between the trays and a non-insertion position in a direction substantially perpendicular to the separation direction of the trays. It consists of a movable support member which is freely provided and supports the playing means, and a support part phase drive means for moving the movable support member, and the separation positioning means are arranged so as to be movable in the separation direction. It is composed of a plurality of tray holding members that hold each of the trays, and a holding member driving means that moves each of the tray holding members, and each of the tray holding members moves alternately along two different planes.

[Operation of the Invention] In the multi-disc storage player having the above structure, when a play command is issued to play a desired disc with the magazine mounted, the separation positioning means moves the lower part of the magazine into the The half and lower halves are separated, and the tray carrying the disc to be played is moved perpendicularly to its main surface to be separated from the other tray, and then the movable carrying member is moved between the trays. A playing means including a turntable is attached to the disc by inserting it through the disc, and then the disc is clamped by a disc clamp mechanism, the pickup is activated, and playing begins.

Further, each of the plurality of tray holding members, which are constituent members of the separating and positioning means and each holds a tray and moves the same, alternately moves along two different planes.

Embodiment Hereinafter, a multi-disk storage player as an embodiment of the present invention will be described with reference to the accompanying drawings.

The main part of the multi-disc storage player is, for example, a player housing 2 that is removably inserted into a holding space that holds the dash board (not shown) of an automobile through an insertion opening formed in the dash board (not shown). The front portion of the player housing, that is, the front panel portion is exposed outside the holding space.

As shown in FIG. 1, a front panel 3 forming the front surface of the player housing 2 is formed with a rectangular insertion opening 3a for inserting and mounting a magazine 5 into a mounting portion within the player housing.

The insertion port 3a extends in the left-right direction. Note that the direction of arrow X is to the left, and the direction of arrow Y is to the front. Further, arrow Z indicates upward. Although not shown, the front panel 3 is provided with an operating section for operating the multi-disc storage player and a display section for displaying the operating status of the player.

As shown in FIGS. 1 to 5, the magazine 5 includes an upper half body 6 and a lower half body 7 that are separable from each other and has a generally flat rectangular parallelepiped-shaped housing, and is arranged and accommodated within the housing. Two types of approximately rectangular plate-shaped trays All and B1 each capable of supporting a disk 9 on its main surface.
．． 2. The lower half body 7 is simply formed into a substantially rectangular plate shape to form only the bottom part of the housing, and the upper half body 5
The housing is formed by integrally connecting a downwardly extending hanging portion to the edge of a rectangular plate-shaped main portion to form the upper surface and side portions of the housing.

Three trays All and two trays B12 are provided, and these are arranged alternately. Tray Al
l and tray B ], 2 has a circular hole 1 in one corner thereof.
．． 1a and 12a, as shown in Figure 2,
Each of these circular holes fits smoothly into a cylindrical member 14 protruding from the inner wall surface of the corner portion of the lower arm body 7. Therefore, as is clear from FIG.
It can be freely stored in a housing that protrudes from the housing. Figure 6 (Rice C) and Figure 7 (Rice C)
), the two types of trays All and B 1.2 have substantially the same shape as a whole, except for the following points.

That is, the claw portions 11. which the operator applies with his fingertips when pulling out each tray out of the magazine 5. b and 12b are different in position, and these claw portions are arranged to be relatively shifted in a plane parallel to the main surface of each tray. Because of this configuration,
When placing a fingertip on the claw portion 11b of one tray, for example, tray All, the other tray B1 adjacent to the tray A is
The trays can be taken in and out of the magazine 5 easily without interference between the claw portions 12b of No. 2 and the fingertips.

In addition, the edges of both trays All and tray B12, in this case, the two edges of each tray formed in a rectangular plate shape, are located on a virtual straight line passing through the center of the disk supporting surface of each tray along the disk supporting surface of each tray. On or in the vicinity of a diagonal line connecting diagonals, a plurality of tray holding arms, which are constituent members of separation and positioning means to be described later, hold two types of held parts 11c and lld and 12c and 12d for holding each tray, respectively. is formed. As is clear from FIG. 6 (ω and mountain) and FIGS. 7(a) and +b, one of the two types of held portions 11 formed on each tray
C and 12c consist of grooves formed on the end face of the tray.

In addition, Fig. 6 (J and (C) and Fig. 7 (a) and (
As shown in C), the other held portions 11d and 12d are formed by slightly recessing the two-sided surface of the tray so that they are thinner than other portions. Note that these held parts 11d and 1
2d may not be made thin, but may be formed to have the same thickness as the other portions. However, such a thin wall contributes to making the magazine 5 thinner.

As is clear from the figure, held parts 11c and lld formed on tray A 11 and held parts 1.2c and 12d formed on the other tray B12 adjacent to tray All are the main parts of the tray. They are arranged to be relatively shifted in a plane parallel to the plane.

That is, each held part 1.1 c and lld, and 1
2c and 12d are not arranged in a straight line in the direction perpendicular to the main surface of each tray, but are offset from each other and distributed along the main surface of the tray. Because of this configuration, the space that must be provided within the player housing 2 for swinging of each tray holding arm (described later) to separate the trays is reduced in the direction perpendicular to the main surface of the tray, and the magazine This makes it easier to make the player 5 smaller and thinner in this direction, and by extension the player as a whole to be thinner.

In addition, as shown in FIG. 6 (■ to FIG. 7(C)), each tray All and tray B12 has cutout portions 11f and 11g in the vicinity of the held portions 11c, lld, 12c and 12d, respectively. , 12f and 12g are formed.

As will be described later, these notches are for avoiding interference between each tray holding arm, which is a component of the above-mentioned separation and positioning means (described later), and the tray adjacent to the tray held by the holding arm I7.

As is clear from FIGS. 6(a) to 7(C), the main surfaces of each tray All and tray B12 are provided with circular recesses 11h for accommodating and positioning the disks 9.
and 12h, and an opening 1 through which a clamper, which will be described later, can be inserted.
1i and 12i are provided. Further, as shown in FIGS. 4 and 5, at the end of the lower half 7 that forms part of the housing of the magazine 5, similar to the above-mentioned trays,
The held parts 7a and 7b held by the tray holding arms (described later) of the separating and positioning means are formed as thin parts that are thinner than other parts. Note that these held portions 7a and 7b may not be made thin, but may be formed to have the same thickness as the other portions.

As shown in FIG. 2, two cylindrical members 16 and 17 similar to the above-mentioned cylindrical member 14 are protruded from the inner wall corner of the lower body 7 of the magazine 5. As shown in FIG. Each tray A11-
and tray B12 are also movable in the axial direction of a columnar member 14 that rotatably supports them, and the columnar member 14 not only acts as a shaft support member that pivotally supports each tray, but each tray is flat. It also acts as a guide member to guide the two so that they are aligned. One cylindrical member 1
By performing two functions in this way, the number of parts is reduced by one compared to a structure in which two members are provided to perform each function individually.

In addition, as mentioned above, each tray A1.1 and tray B12
is projected from and housed in the magazine 5 by rotating around the cylindrical member 14. The protruding storage operation of the tray is not limited to rotation as described above, but a configuration in which the tray is reciprocated in a linear manner can be considered, or by adopting such a rotation configuration, the movement of the tray is always performed smoothly. This provides good operability when the operator takes the tray in and out of the magazine to load or replace disks.

Here, a locking mechanism for fixing the upper half body 6 and the lower half body 7, which constitute the housing of the magazine 5, to each other will be explained.

As shown in FIGS. 2 to 5, a movable locking member 19 formed in a disk shape and annular shape is attached to the inner wall surface of the upper half body 6 so as to be freely rotatable along its main surface. Specifically, as shown in FIGS. 2, 4, and 5, on the inner wall surface of the upper half 6, there is a supporting member 20 having an oval-shaped cross section perpendicular to the center of the ring. The movable locking member 19 is fixed to the support member 20 by adhesive or the like at the end surface.
It is arranged so that it is slidably held at its inner circumferential portion by the lower side portion and the upper half body 6.

Three protruding parts 19a to 19c are protruded from the outer circumference of the movable locking member 79, and semicircular notches 19d to 9f are formed at the tip of each protruding part, Annular grooves 14a, 16a as locked parts formed on the outer peripheral surfaces of the tips of the three cylindrical members 14, 16 and 17 mentioned above.
and 17a, each of the notches 19d to 19f can be smoothly fitted with a capacity of 1.2J. FIG. 8 shows a perspective view of, for example, the cylindrical member 14 and the overhang portion 19a that engages with it. Note that the relationships between the other two columnar members 16 and 17 and the overhanging portions 19b and 19c are also similar. That is,
Each notch of the movable locking member 19 provided on the upper half body 6 corresponds to each annular groove 14a, 16a, and 17a of the three cylindrical members 14, 16, and 17 fixedly installed on the lower half body 7. 19d
By fitting the upper half body 6 and the lower half body 7, the upper half body 6 and the lower half body 7 are fixed to each other, and when the fitted state is released, the two halves can be separated. Note that the position of the movable locking member 19 in which the notches 19d to 1.9f are fitted into the respective annular grooves 4a, 16a, and 17a is referred to as a locking position, and the movable locking member 19 is released from this fitting. The position of member 19 is referred to as the unlocked position.

As shown in FIG.
7, one projecting portion 19c of the movable locking member 19
The direction in which the notches 19d to 19f of the respective overhanging parts 19a to 19c fit into the annular grooves 14a, 16a and 1.7a of the respective cylindrical parts 414.16 and 17 (in the direction of arrow G) ) is swingably provided via a support pin 21a. In addition, the support bin 21a has
A spring member 22 that applies a biasing force to the biasing lever 21 is fitted therein. These biasing levers 21 and spring members 2
2 constitutes a biasing means for biasing the movable locking member 19 toward the above-mentioned locking position. This biasing means, a series of movable locking members 19, and three cylindrical members 14 as locked portions with which the movable locking members engage.
16 and 17 constitute a locking mechanism that fixes the upper half body 6 and the lower half body 7 to each other.

By providing the locking mechanism, when the operator handles the magazine 5 to load or replace a disk in the magazine 5, the operator activates the locking mechanism to lock the upper half body 6 and the lower half body 7 together. By fixing them firmly, the upper half body 6, the lower half body 7, and each tray containing them can be prevented from being accidentally separated.

As mentioned above, since the locking mechanism is configured to simultaneously fix the upper half body 6 and the lower half body 7 at three points, each part of the upper half body 6 and the lower half body 7 can be accurately connected without being distorted. be given Further, since the movable locking member 19 is formed in a substantially disk shape and rotates along its main surface, the space that must be provided in the magazine 5 for the operation of the movable locking member 19 is small. This contributes to the miniaturization of the internal body and, by extension, the player as a whole. However, the shape and movement of the movable locking member 19 are not limited to this configuration; for example, various other configurations may be used, such as an arm shape that can swing freely, or a lever shape that can freely reciprocate linearly. Needless to say, it is applicable.

In addition, as mentioned above, the three cylindrical members 14, 16 and 17 that support and guide each tray are used to fix the upper half body 6 and the lower half body 7 to each other in this way. Since it was also used as a component, the number of parts was kept small.

Next, a description will be given of a performance means transport mechanism that moves a performance means including a turntable, a pickup, and a disc clamp mechanism, and mounts the performance means on a disc to be played in the magazine 5.

As shown in FIGS. 9 to 12, the magazine 5 is inserted into a mounting portion in the housing 2 of the play kino 1. The upper half body 6 and the lower half body 7 constituting the magazine 5, as well as the ends and side ends of each of the trays All and B12 in the magazine insertion direction, are arranged in a straight line in the arrangement direction of the trays. As if forming two grooves,
Notches 6a, 6b, 7d, llj, llk, 12j and 12k are formed. Regarding the lower body 7,
A notch at the end in the magazine insertion direction is not shown.

As shown in FIGS. 9 and 10, two guide shafts 24 and 2 are provided in the housing 2 of the play kino 1 so as to fit into the two longitudinal grooves formed by these respective notches.
5 are arranged to extend in the vertical direction, and one guide shaft 25 is fixed to the player housing 2. These guide shafts 24 and 25 slide on each tray All and tray B 1.2 and the lower half 7 which are separated from each other as will be described later, and guide them in the separation direction. As shown in a perspective view of one of the guide shafts 24 in FIG.
a and 25a are formed, and the magazine 5! The notches 6a and 6b of the upper half 6, which forms the upper half of the housing, fit into the upper end portions of the guide shafts 24 and 25, so that the upper half 6 is supported by the flanges 24a and 25a, and the upper The downward movement of the half body 6 is restricted. Note that while one guide shaft 25 is fixed to the player housing 2 as described above, the other guide shaft 24 is swingable relative to the player housing 2 via the support pin 26a. The lever member 26 is provided so as to protrude above the free end thereof, and is biased toward the magazine 5 by a spring member 27 . Therefore, the guide shaft 24 is retracted by the lever member 26 swinging clockwise in FIG. 9 while being pushed by the magazine as it is inserted into the player housing 2, and the magazine 5 The magazine 5 is fitted into each notch by being returned by the biasing force of the lever member 26 or the spring member 27 at the same time as the insertion of the magazine is completed.

Further, as shown in FIGS. 3 and 9, a disk-shaped movable locking member 19 that fixes the upper half 6 and lower half 7 of the magazine 5 to each other has three protruding portions. Another projecting portion 19g is integrally formed near one of the projecting portions 19a to 19c, and when the magazine 5 is installed in the player housing 2 as described above, The guide shaft 25 is in a state of pushing this overhang 19g. As a result, the movable locking member 19 is rotated counterclockwise in the drawing, and each of the projecting portions 19a to 19c of the movable locking member 19 engages with the three cylindrical members 14, 16 and 17. Separate from the upper body 6
The fixed state between the lower half body 7 and the lower half body 7 is released, and the two can be separated.

The playing means transport mechanism described below vertically separates the upper half 6 and lower half 7 of the magazine 5, which can be separated as described above, in response to a playing command, and carries a disc to be played. After the tray is separated from the other trays, a playing means including a turntable or the like is brought to correspond to the disc and mounted thereon.

First, as described above, the separating and positioning means has two sets of six tray holding arms each driven by two cam members 29 and 30, and each tray of the magazine 5 is controlled by both tray holding arm groups. , a held portion 1-IC1ll formed along the disk supporting surface on an imaginary straight line passing through the center of the disk supporting surface or at an end in the vicinity thereof.
d, 12C and 12d are retained. In other words, each tray formed into a rectangular plate shape is held by the tray holding arm group on or near a diagonal line connecting two diagonals thereof. On the other hand, both the magazine 5 and the player housing 2 surrounding it are formed into a rectangular parallelepiped shape. In this structure in which the rectangular parallelepiped magazine 5 is surrounded by the rectangular parallelepiped player housing 2, two sets of trays are held at the diagonal corner of each tray, and therefore near the two diagonal corners of the magazine 5 as a whole, as described above. By arranging the arm groups separately, a relatively large space can be obtained in a portion located between the two tray holding arm groups, that is, in the inner corner of the player housing 2.

Therefore, the holding arm driving means comprising the aforementioned cam members 29 and 30, motor 32, etc. can be efficiently disposed in this space.

Further, as mentioned 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 tray at two locations near the diagonal line thereof, thereby holding the disks on the tray. Although the trays are separated in the direction perpendicular to the plane, each tray has two guide shafts 24 and 2 as described above.
5 without shifting from each other, it is not necessary to hold the tray at two locations as described above, but by one of the two tray holding arm groups, for example, the tray holding arms 43 to 48. It is also possible to have a configuration in which only one location on each tray is held and the moving force is applied. Therefore, the remaining tray holding arm group, that is, the tray holding arms 73 to 78, cooperates with this one set of holding arm groups to hold each tray and move the trays in parallel so that the trays do not tilt. This acts as a tray tilt regulating means. Note that the tray holding arms 43 to 48 are referred to as a first tray holding member, whereas each of the tray holding arms 73 to 7 of the other set is referred to as a first tray holding member.
8 is referred to as a second tray holding member.

By providing such a tray inclination regulating means, the tray is always moved in parallel without inclining, so that the disk on the tray will not shift due to the inclination of the tray.
This ensures that playing means including a turntable, which will be described later, etc., are always mounted reliably and smoothly on the disc.

Note that the driving force applying means for applying a driving force to each of the tray holding arms 73 to 78 serving as the above-mentioned tray tilt regulating means is exclusively applied to each of the tray holding arms 43 to 48 that control the separation operation of each tray. Since the motor 32 that applies the driving force is also used, there is no need to provide a special driving force applying means exclusively for the tray tilt regulating means, and the number of driving sources can be reduced.

Here, the configuration of each tray holding arm group described above will be explained in more detail. As shown in Figure 9 and Figure 1,
Six tray holding arms 43 to 48, which constitute one group of tray holding arms disposed at the rear of the magazine 5, are arranged so as to alternately swing along two different virtual planes. . That is, the six tray holding arms are alternately divided into two subgroups, in this case tray holding arms 43, 45 and 47 are in one subgroup, and the remaining three tray holding arms 44, 46 and 48 are in another subgroup. The virtual planes along which the tray holding arm groups of both subgroups are to be moved are shifted from each other in the horizontal plane. Because of this configuration, if these two imaginary planes are made to overlap each other in the horizontal direction as shown in the figure, compared to the configuration in which all the tray holding arms 43 to 48 are moved along one common imaginary plane, The projected area of the virtual plane required for moving each tray is halved, making it easier to downsize the player as a whole.

Further, as shown in FIG. 9, tray holding arms 43, 45 and 47 as one small group and tray holding arms 44, 46 and 47 as one small group are arranged offset from each other in the horizontal plane as described above. 48, a partition member 88 is interposed to separate these two sets. By this partition member 88, the tray holding arm groups of the two subgroups are accurately guided, and are prevented from interfering with the tray holding arm groups of the other group due to distortion, etc., and operation is performed smoothly.

On the other hand, as is clear from FIGS. 9 and 12, the six tray holding arms 73 to 78 disposed at the rear of the magazine 5 are also arranged alternately in the same manner as the tray holding arms 43 to 48 described above. divided into two small groups, these two
The two subgroups are arranged staggered in the horizontal plane, and
A partition member 89 is provided between them.

Note that, as described above, each tray holding arm 43 to 48
Further, each of the tray holding arms 73 to 78 is configured to swing, but the movement of each tray holding arm is not limited to this swing, but various other movements such as parallel movement are possible. However, by adopting such a swinging configuration,
The operation of each tray holding arm is always performed reliably and smoothly.

Next, a mechanism that constitutes the above-mentioned playing means conveying mechanism together with the above-mentioned separation and positioning means will be explained.

As shown in FIG. 2, FIG. 9, FIG. 15, and FIG. 16, a cylindrical support shaft 95 is provided in the player housing 2 in the vertical and vertical directions so as to be located to the left of the mounted magazine 5. That is, each of the trays described above is arranged to extend in the direction in which they are to be separated, and is fixed to the player housing 2 at its lower end. A male screw 96 formed in a cylindrical shape is rotatably fitted onto the support shaft 95 . A longitudinal movable support member 98 formed in the shape of a flat plate is fitted at one end of the upper end of the male screw 96. This movable carrier member 98 extends in the horizontal direction. That is, the movable supporting member 98 is swingable about the support shaft 95 in a direction perpendicular to the direction in which the trays are separated, and is also movable along the support shaft 95. Furthermore, the movable support member 98 swings between an insertion position where it can be inserted between the separated trays and a non-insertion position where it can be removed from between the trays. The swinging position of the movable support member 98 shown by the two-dot chain line in FIG. 2 and the solid line in FIG. 9 is the insertion position;
This is the swing position or the non-insertion position shown by the two-dot chain line in the figure. Note that this insertion position is also referred to as a position facing the disk because when the movable support member 98 is in this position, the movable support member can face the recording surface of the disk 9 on the tray. The non-inserted position is also referred to as a non-opposing position.

The movable carrier member 98 is also movable along the support shaft 95 between a low position shown in solid lines in FIG. 15 and a high position shown in dash-dotted lines.

A turntable 100 is provided near the swinging end of the movable carrier member 98 . A guide shaft 101 and a worm 102 are arranged parallel to each other on the movable support member 98 along the longitudinal direction of the movable support member, and one end 103b of the carriage 103 is screwed into the worm 102. Moreover, it is slidably supported by a guide shaft 101 at the other end. However, the guide shaft 101 and the worm 102 are not shown in FIG.

The carriage 103 houses an optical pickup including an objective lens 105 (shown in FIG. 9). Since this optical pickup is similar to a known one, it will not be described in detail.It includes a servo mechanism etc. that servo drives the objective lens 105 in the focusing direction and the tracking direction, and it directs the laser beam emitted from the laser beam irradiation device to the disk. The recorded information is read by irradiating the recording surface and changing the reflected light. As shown in FIG. 9, a substantially rectangular opening 98a is formed in the movable support member 98 so that the objective lens 105 can access the recording surface of the disk 9. As shown in FIG. Also, Fig. 9 and 1
As shown in FIG. 6, the guide shaft 101 that guides the carriage 103 is disposed within another elongated opening 98b formed in the movable support member 98, and this opening is utilized as an installation space for the guide shaft 101. . Therefore, the space that the guide shaft 1-01 should occupy is reduced, contributing to miniaturization of the player.

As shown in FIGS. 9 and 16, the above-mentioned worm 102
is a motor 1 disposed on the proximal end side of the movable support member 98;
08, a plurality of pulleys and their hooks are rotated by applying torque through a power transmission mechanism 109 consisting of two rotated belts. Further, as shown in FIG. 9, a carriage 1-
03 engages with the actuator 111a and is activated, the carriage 103 moves towards the turntable 100.
A detection switch 111 is provided to detect when the movement limit position is reached.

Further, as shown in FIG. 9, on the movable support member 98,
A photosensor 112 is located near this detection switch 1]1.
is provided. As shown in FIGS. 9 and 12, five slits 113a are vertically arranged and can be detected by the photosensor 12 when the movable support member 98 is in the non-inserted position. An address plate 113 is attached to the left inner wall surface of the playkeno 1 housing 2.

The guide shaft 101 described above, the worm 102,
The motor 108, the power transmission mechanism 109, and the detection switch 11 constitute a pickup guide drive means that guides and moves the carriage 103 carrying the pickup toward and away from the turntable 100.

As shown in FIGS. 2 and 16, a clamper arm 115 is disposed along the lower surface of the movable support member 98, and is formed near the proximal end of the movable support member 98 so as to extend downward. The support pin 116 is swingably attached to the hanging portion 98d at one end thereof. The clamper arm 11-5 swings in a plane including the vertical direction.

At the swinging end of the clamper arm 115, a suppressing member 117 for pressing the disc 9 to be played toward the disc supporting surface of the turntable 100, that is, a clamper is provided with a spherical bearing 8 (shown in FIG. 16). It is rotatably attached through the

The above-described clamper arm 1] 5, the pressing member 118,
These and related peripheral small members constitute a disk clamp mechanism that clamps the disk 9 to the disk supporting surface of the turntable 100. Further, this disk clamp mechanism, the turntable 100, the optical pickup including the carriage 103, and the pickup guide drive means including the guide shaft 101, the worm 102, the motor ]08, etc. are collectively referred to as the performance means. That is, the movable support member 98 supports this playing means and swings.

Next, a description will be given of a supporting member driving means for swinging the movable supporting member 98 and moving it along the support shaft 95, which is a swinging support axis.

FIG. 15 is a view taken along arrows xv-xv in FIG. 9, including a partial cross section, and as shown in FIG. 9 and FIG. Motors 121 and 12 are provided in front and behind the motor 95, respectively.
2 are arranged.

A motor 121 provided at the rear of the support shaft 95 is used to move the movable support member 98 along the support shaft 95, and a motor 122 provided at the front is used to swing the movable support member 98. It is.

Note that, as will be described later, the motor 122 also applies driving force to the disk clamp mechanism described above.

As is clear from FIG. 15, a cylindrical female screw 123 is screwed into the male screw 96 which is rotatably and slidably fitted onto the support shaft 95 and carries the movable support member 98. A gear 123a is integrally formed at the lower end of this female thread 123, and the torque from the motor 21 is transmitted to this gear via gears 124, 125a, worm wheel 125b, worm 126, and gears ]-27 and 128. 123a and the female thread 123.

On the other hand, a cylindrical member 30 is rotatably fitted onto the female thread 123, and a cylindrical pin 1.30a is protruded from the upper end of the cylindrical member.
This pin 130a is inserted through a circular opening 98f formed at 8 with a predetermined gap. A gear 130b is integrally formed at the lower end of the cylindrical member 130, and the gear 132, face gear 133, worm 134, worm wheel 135a, gear 1.35b, gears 136 and 137 are sequentially disassembled to drive the motor 122. Torque from is transmitted to this gear 130b and the cylindrical member 130. Note that the gears 136 and 137 are not integral with each other, but are both concentrically supported by a shaft 139.
As shown in the figure, a pin 137a protruding from the upper stop surface of the lower gear 137 is slidably fitted into an arcuate groove 36a formed on the lower main surface of the upper gear 136. ing. As shown in FIG. 9, the support shaft 95 that pivotally supports the movable support member 98 is placed in the aforementioned non-insertion position, that is, the position shown by the two-dot chain line in FIG. A spring member 840 serving as a bias spacing imparting means for imparting a bias spacing toward the surface is fitted.

The above motors 121 and 122 and gears 123a and 1
24 and 125a, worm wheel 125b, worm 126, gear] 27 and 128, pin] 30
a, gears 130b and 132, and face gear 133
, a worm 134, a worm wheel] 35a,
Gear 135b.

136 and 137 and the pin 137a constitute a torque applying means that selectively applies torque to each of the female thread 123 and the cylindrical member 130. Further, the torque applying means, the female screw 123, the cylindrical member 130, and the aforementioned male screw 96 cause the movable support member 98 to swing around the support shaft 95 and to move along the support shaft 95. A driving means is configured. Further, the turntable 1
A playing means conveying mechanism is constructed to move the above-mentioned playing means such as 00 and attach it to the disc to be played.

As described above, the movable support member 98 is configured to swing, but the movement of the movable support member 98 is not limited to rocking as described above, but various other movements such as parallel movement can be considered. It will be done. However, by adopting such a swinging configuration, the movement of the movable support member 98 is always performed reliably and smoothly.

Further, as described above, the movable support member 98 is swingably attached to the support shaft 95 so as to be able to swing between the insertion position where the movable support member 98 is inserted between the trays of the magazine 5 and the non-insertion position, and the movable support member 98 is separated from the other trays. Because of the configuration in which the movable support member 98 is movable also in the axial direction of the support shaft 95 in order to bring the playing means to a position corresponding to the tray that has been placed,
The player as a whole has been made smaller. However, as another configuration for making the movable support member 98 movable in two different directions, for example, the movable support member 98 may be mounted in such a manner that it can only swing relative to the support shaft 95. It is conceivable to provide a predetermined moving member that is movable in the tray separation direction and to mount the support shaft 95 on this moving member. However, in such a virtual configuration, compared to the implementation side configuration,
The movable member and a guide mechanism for movably guiding the movable member in the tray separation direction are required, leading to an increase in the number of parts and an increase in the size of the player as a whole.

By the way, as is clear from FIG. 9, the arrangement position of the support shaft 95, which is the pivot point of the movable support member 98, is determined by the holding position of each tray by the tray holding arms 73 to 78, which are disk holding means. , is located in front of the held parts 11C and 12c of each tray, and is set at a position closer to the insertion opening 3a for inserting the magazine 5 formed in the player housing 2 than these held parts. ing. By arranging the pivoting center of the movable support member 98 at such a position, a relatively large space is formed in the central and inner parts of the player housing 2, and the above-mentioned support member driving means for operating the movable support member 98 and This space can be used as the space occupied by other mechanisms, increasing the degree of freedom in selecting the setting positions of the mechanisms inside the player.

A configuration will now be described in which the power generated by the motor 122 for swinging the movable support member 98 also operates the disk clamp mechanism described above.

As shown in FIGS. 9, 16, and 17, an intermediate lever 142 or a screw 14 is provided on the lower surface of the proximal end of the movable carrier member 98.
2a (shown in FIG. 16), it is swingably mounted at its central portion in a horizontal plane. 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 support member 98.
The cam surface of the cam portion can slide into a hanging portion 142b (the reference numeral is shown only in FIG. 6) formed at one swinging end of the cam portion. As shown in Fig. 16, the intermediate lever 1
A hanging part 142b is also formed at the other end of the swinging part 42, and a protrusion 142C protruding from this hanging part 142b is a component of the clamper arm 1, which is a component of the disk clamp mechanism.
15 is brought into contact with the hanging portion 1] 5a formed in FIG. 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 contacts and presses one hanging portion of the intermediate lever 142. Intermediate lever 14
2 swings around a screw 142a that pivots it,
A protrusion 14 formed on the other swinging end of the intermediate lever cord 42
2C pushes the hanging part 115a of the clamper arm 115,
It is configured so that the disc can be clamped.

FIG. 18 shows the configuration of a control unit that controls the operation of each internal mechanism of the multi-disc storage player configured as described above, and
The UI 50 controls the photosensors 84, 112 and
RAM 15 in response to each signal from the detection switch 111 and the keyboard 152 consisting of a switch group (not shown).
3, motors 32.108.121 and 122
and turntable 1.00 and pickup 155
issue commands to.

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

First, when the keyboard 152 shown in FIG. 18 is operated by the operator to issue a performance command for playing a desired disc and the number of songs is specified, the multi-disc storage player is operated as shown in FIGS. It operates according to the flowchart shown in FIG.

As shown in FIG. 19, when a performance command is issued and a song number is specified (step Sl), the control section first performs the following steps.
It is confirmed that the magazine 5 is installed in the player/% housing 2 by a detection signal issued by a magazine detection means (not shown) (step S2). If the magazine 5 is attached, each internal mechanism is activated by executing the 10th-decking subroutine (step S3) shown in FIGS. 19 and 20. Incidentally, upon execution of this tenth loading subroutine, the magazine 5 has only been inserted into the player housing 2, and the lower half 7 and upper half 6 of the magazine 5 have not yet been separated.

Note that a movable locking member that fixes the upper half 6 and lower half 7 of the magazine 5 to each other when the magazine 5 is inserted into the player housing 2 by the operator]
The guide shaft 25 shown in FIG. 9 pushes one of the projecting portions 19g of 9 by the reaction force of this mounting force. As a result, the movable locking member 19 is rotated counterclockwise in FIG. 2 and FIG. 14. The upper half body 6 and the lower half body 7 are separated from each other, and the fixed state between the upper half body 6 and the lower half body 7 is released, and the two can be separated. Further, in this state, the movable support member 98 on which the playing means including the turntable 100 is mounted is in the non-insertion position shown by the two-dot chain line in FIG.

Also, when installing the magazine 5 into the player housing 2, each tray holding arm 43 to 48 and 73
78 respectively hold each tray and the held portion of the lower half body 7.

As shown in FIG. 20, when the above command is issued, the control section first rotates the motor 32 in the normal direction (step S4) and
The two cam members 29 and 30 are rotated forward by an angle θ, for example, 30°, and each tray holding arm 43 to 48 and 7
3 to 78 are swung from the states shown in FIGS. 11 and 1.2 to the state shown in FIG. 22. by this,
The lower half 7 of the magazine 5 is moved downward and separated from the upper half 6. Furthermore, as shown in FIG. 22, at the same time as the lower half body 7 and the upper half body 6 are separated, the lowest tray All of the five trays accommodated in the magazine 5 is separated from the other trays. and brought to a position corresponding to the playing means including the turntable 100.

If the disk containing the designated track among the five arranged trays is supported on the third tray A1 from the bottom, the motor 32 is further rotated in the normal direction (step S5), The cam members 29 and 30 synchronously move further 6
The disk is rotated 0' in the normal direction, and the state shown in FIG. 22 passes through the state shown in FIG. 23, and then the state shown in FIG. 24 is reached, and the tray All carrying the desired disk is separated from the other trays. Further, along with this tray separation operation, the motor 121 is rotated in the normal direction (step S5), and the movable support member 98 carrying the playing means is moved upward from the lowest position by a distance equivalent to the thickness of two trays. The tray 11 is moved and positioned at a position corresponding to the tray 11 separated from other trays. Note that the rotation angles of both cam members 29 and 30 and the movable support member 9
8 is the address plate 83 and 11 detected by the two photosensors 84 and 112 mentioned above.
The control section counts the number of slits 83a and 113a in each of the three slits 83a and 113a using a counter provided therein, and detects the number based on this count value. Further, 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 disc, and the address of the search disc, which is the disc being searched.

When the address of the current disk matches the address of the search disk (step S6), motor 32 and motor 1
21 is stopped (step S7). Next, the motor 122 is rotated in the normal direction (step S8), and the movable support member 98, on which the playing means is mounted on its free end, is directed from the non-inserted position shown by the two-dot chain line to the inserted position shown by the solid line in FIG. The turntable 100 is then swung and the disc clamp mechanism is activated to attach the turntable 100 to the disc to be played. This operation will be explained in further detail.

As mentioned above, the output of the motor 122 for swinging the movable carrier member 98 is transmitted through the gear 132 and the base gear 133.
, worm 134, worm wheel 135a, gear 1
35b and 136, pin 137a, gears 137 and 13
0b, is applied to the movable carrier member 98 via the cylindrical member 130 and the pin 130a in sequence. Before the motor] 22 starts normal rotation, an arcuate groove 136a formed on the lower main surface of the gear 36 and a pin 137a implanted on the upper main surface of the gear 137 to slidably fit into this groove. and have the positional relationship shown in FIG. When the motor 122 starts normal rotation in this state, the movable support member 98 is moved toward the insertion position (the swing position shown by the solid line in FIG. 9) by the spring member 140 attached to the support shaft 95 that pivots the movable support member 98. Since it is biased, it is swung by the biasing force of the spring member 140. Therefore, the above two gears 136 and 1
37 are the arc-shaped groove 136a and the pin 1 provided therein.
37a are rotated synchronously while maintaining the relative positional relationship shown in FIG. 17. In other words, the movable support member 98 is allowed to swing due to the biasing force of the spring member 140 due to the rotation of the motor 122. Thus, when the movable support member 98 swings to the insertion position shown by the solid line in FIG. 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 the two gears is prevented from further operation. However, as mentioned above, both gears 136 and 137
37a is relatively rotatable within the range in which it slides within the arcuate groove 136a.

The motor 122 continues to rotate in the normal direction even after the above-mentioned positioning of the movable support member 98, whereby the gear 36 is rotated relative to the other gear 137 which is in a fixed state. As mentioned above, the upper main surface of this gear 136 has a cam portion ] 36
Since b is integrally formed, as the gear 1360 rotates, the cam portion 136b comes into sliding contact with the intermediate lever 142, causing it to swing, as shown in FIG. This results in
Drooping portion 115a of the clamper arm 115 shown in FIG.
is pushed by the protrusion 142C of the intermediate lever 142, the clamper arm swings (in the direction of arrow H) from the non-clamping position shown by the two-dot chain line to the clamping position shown by the solid line, and the pressing member 117, that is, the clamper pushes up the disk 9. and then separate it from the tray and clamp it to the turntable 100. Note that this rotation of the cam portion 136b is performed after the movable support member 98 reaches the above-mentioned insertion position, so that the maximum diameter portion of the cam portion 136b and the intermediate lever 14 are rotated.
2 are prevented from interfering with each other. Moreover, if this clamping operation is performed while rotating the turntable 100, clamping errors will be reduced.

After the above operation, the controller waits for a certain period of time to elapse (indicated by step S9 in FIG. is stopped (step 510). Thereafter, the servo driving means (not shown) for the objective lens 105 included in the pickup is activated, and the motor 108 is rotated in the normal direction (step 81).
In step 1), the carriage 103 containing the pickup starts moving, and the performance starts.

After confirming that the first disc has finished playing (step 51.2), the control unit stops the forward rotation of the carriage transport motor 108 and stops the pickup operation, and immediately rotates the motor 08 in the reverse direction. (Step 5)
13). By reversing the motor 108, the carriage 103 carrying the pickup is brought closest to the turntable 100 mounted on the swinging end of the movable carrier member 98. When the carriage 103 approaches the turntable 100, a protrusion formed on the carriage 103 engages with the actuator 111a of the detection switch 111 shown in FIG. 9, thereby activating the detection switch. The control unit recognizes that the carriage 103 has come closest to the turntable 100 based on the detection signal emitted from the detection switch 1] 1 (step 514), and accordingly controls the motor 1.
08 to stop the carriage 103 (step 515).

After the above operation, the motor 122 is reversed (
In step 516), the disk clamp is released and the movable support member 98 is swung from the insertion position shown by the solid line in FIG. 9 to the non-insertion position shown by the two-dot chain line.

Note that this disc clamp release operation and the return operation of the movable support member 98 are performed by following the reverse process of the aforementioned disc clamp operation and the swinging operation of the movable support member 98 to the insertion position, so detailed description will be omitted. do not.

As shown in FIG. 9, when the movable support member 98 returns to the non-inserted position, the photosensor 112 provided on the swing groove of each movable support member can detect the address plate 113 to be detected. Reach the location and detect it.

For example, the control unit recognizes that the return operation of the movable support member 98 is completed based on the detection signal emitted from the photosensor 112. In step 517), the motor] 22
is stopped to stop the movable carrier member 98 (step 518).

By the way, as is clear from the above description, in the multi-disc storage player, after the playing of the discs is completed, and before the movable supporting member 98 returns to the non-insertion position, that is, the position not facing the disc that was being played,
Carriage 103 on movable carrier member 98 is brought closest to turntable 100 .

With this configuration, the player can be made smaller. This is because, as shown in the embodiment, the player housing 2 is usually formed in the shape of a rectangular parallelepiped, and since the disk accommodated therein is circular, relatively large spaces are formed at the four corners inside the player housing 2. Therefore, when the longitudinal movable support member 98 is in the non-opposed position, the movable support member is configured to be located close to and along the inner wall surface of the player housing 2, so that the end of the movable support member 98 The section is necessarily accommodated in one of the four corner spaces. Therefore, if the movable support member is configured to be located close to and along the inner wall surface of the player housing 2 after the end of the performance as described above, the movable support member 9
The end portion of 8 is necessarily accommodated in one of the four corner spaces. Therefore, if the carriage 103 is moved to the end of the movable support member 98 after the end of the performance as described above, and then the movable support member is returned to the non-opposed position, this corner space is used for the carriage 103 when the performance is not performed. Player housing 2
This increases the efficiency of space utilization inside the player, making it easier to downsize the player.

Through 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 section checks whether there are any more designated disks (step 520), and if there are two or more designated disks, The 20th-daying subroutine (step 521) shown in FIGS. 19 and 21 is executed to operate each internal mechanism.

In the 20th playing subroutine, the control unit first checks whether the second disc to be played is located above or below the disc that has finished playing first (step 522). If the tray carrying the second designated disk among the five trays arranged is tray A1.1 at the top position,
The control unit rotates the motor 32 in the forward direction (step 823) to
The two cam members 29 and 30 are further rotated 60' in the normal direction, and the state shown in FIG. 24 is changed to the state shown in FIG. 25, and then the state shown in FIG. 26, and the tray All at the uppermost position is separated from the other trays. In addition, along with this tray separation operation, the motor 121 is rotated in the normal direction (step 523), and the movable support member 98 carrying the playing means is moved from the position determined in the above-described 10th-daying subroutine to the tray 2.
It is raised by a distance corresponding to the thickness of the tray, and is positioned at a position corresponding to the lowest tray All separated from the other trays as described above.

On the other hand, the second disc to be played is, for example, the second disc from the top (fourth from the bottom) of each tray in which five discs are arranged.
If the tray B12 is held on the tray B12 (the second sheet), the control section reverses the motor 32 (step 524) to reverse the two cam members 29 and 30, changing the state shown in FIG. 24 to the state shown in FIG. Then, the second tray B12 from the top is separated from the other trays. In addition, along with this tray separation operation, the motor] 21 is reversely rotated (step 524), and the movable support member 98 is moved a distance corresponding to the thickness of one tray from the position determined in the above-described tenth-decking subroutine. Then, the playing means is positioned at a position corresponding to the second tray B12 from the top.

As a result of the above operation, when the address of the current disc matches the address of the second disc to be played, which is the search disc (step 525), the motor 32 and the motor 121 are stopped (step 526). Step S in the 10th-ding subroutine
Based on steps S27 to S37 similar to steps S8 to S18, each mechanism is activated to play the second disc.

After this, as shown in FIG. 19, the presence or absence of unplayed discs after the third one is checked (step 540), and if three or more discs are specified, they are played according to the 20th playing subroutine described above. However, if all the specified discs have been played, put all mechanisms into playback standby mode, or
Or stop the operation.

As is clear from FIGS. 22 to 26, about half of the free end of each of the tray holding arms 43 to 48 and 73 to 78 holds the tray separated from the other tray groups. is parallel to the tray it holds. For example, in FIG. 25, about half of the free end of the tray holding arm 44 that holds the second tray B12 from the top separated from the other trays is parallel to the tray B12 that it holds. Because of this configuration, the turntable]00
The playing means including the play means and the movable support member 98 mounted thereon can always be smoothly inserted between the trays without interfering with each tray holding arm, and the playing means can be reliably and smoothly attached to the disc.

Effects of the Invention As detailed above, in the multi-disc storage player according to the present invention, the magazines are arranged and housed in the housing, which includes a pair of upper halves that can be separated from each other, and the housing. It is composed of a plurality of plate-shaped trays each capable of supporting a disc on its main surface and protruding from the housing along each main surface and can be housed therein. separating and positioning means for separating and selecting a tray carrying a desired disk from among the trays, holding the tray, separating it from other trays in a direction perpendicular to the main surface of the tray, and positioning the tray; A performance device including a turntable, a pickup, and a disc clamping mechanism, which is movable between an insertion position and a non-insertion position in which the trays can be inserted in a direction substantially perpendicular to the separation direction of the trays, and is movable in the separation direction. A movable support member carrying means and a support member drive means for appropriately moving the movable support member in each of the above-mentioned directions, and a tray carrying a disc to be played is separated from other trays by the separation and positioning means. After
The movable supporting member is inserted between the trays, the playing means is mounted on the disc, and the disc is clamped by the disc clamp mechanism, and the pickup is activated to start playing.

Because of this configuration, the space that must be provided in the player housing to mount the playing means to the disc to be played is extremely small, and the player as a whole can be miniaturized. It can also be used by storing it within the formed space.

Further, in the multi-disc storage player according to the present invention, each of the plurality of tray holding members, which are constituent members of the separating and positioning means and for holding and moving each tray, alternately holds two different surfaces. are arranged to move along the That is, the tray holding members are alternately divided into two groups, and the surfaces along which the tray holding members of each group move are shifted from each other.

Therefore, compared to a configuration in which all the tray holding members are moved along one surface by making these two surfaces overlap each other, the projected area of the surface necessary for moving the tray is halved. The player has been made smaller.
