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, the selected
When transporting a disc from the magazine onto the turntable, the direction parallel to the disc supporting surface of the turntable,
The disks are moved in two directions perpendicular to this direction, that is, in the direction in which the disks in the magazine are arranged, and the above-mentioned disk ejecting and transporting mechanism is responsible for 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 movement of the disk in a 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. In addition, a sliding member 257 is provided near the magazine.
is provided to move back and forth linearly, and is engaged with the tray push-out member 256 at its forward movement direction end 257a, and is moved by a drive means (not shown) to engage the tray push-out member 256. Apply a rotational moment to make it rotate.

Note that, as shown in FIGS. 29 and 30, two bottles 256a are provided protruding from the tray push-out member 256.
The tray pushing member 256 is guided by this pin 258a 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 disc 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 256 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 above-mentioned points, and its object is to provide a device which is extremely compact and suitable for use in a vehicle, and which also allows the attachment of a playing means to the disc.

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 upper half body and the upper 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 that is freely provided and carries the playing means, and a support member driving means that moves the movable support member, and the separation positioning means is provided so that it is movable in the separation direction and moves toward the edge of the tray. and a holding member drive means for moving the tray holding members. The tray is held on or near the tray.

[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 upper half of the magazine, which is the 7X housing part. The body and the upper body are separated, and the tray carrying the disc to be played is moved perpendicularly to its main surface to be separated from the other trays, and then the movable carrying member is inserted between the trays. A playing means including a turntable is attached to the disc, and then the disc is clamped by the disc clamp mechanism, the pickup is activated, and the performance begins.

Further, the tray holding member, which is a constituent member of the separating and positioning means and which holds and moves the tray, is arranged so that the tray is positioned along the disk holding surface of the tray on a straight line passing through the center of the disk holding surface or in the vicinity thereof. hold.

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 rectangular insertion opening 3a is formed in the front panel 3 forming the front surface of the player/X Uji leg 2 for inserting and mounting the magazine 5 into the mounting section in 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 Tray B, each of which can support a disk 9 on its main surface]-
2. The lower half 7 is simply formed into a generally rectangular plate shape to form only the bottom surface of the housing, and the upper half 6 is formed by the edges of the main portion of the rectangular plate shape to form the top and side surfaces of the housing. It is made by integrally joining together a hanging part that extends downward.

Three trays All and two trays B1.2 are provided, and these are arranged alternately. Tray All and tray B12 have a circular hole 11 in one corner.
a and ], 2 a, 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 half body 7. Therefore, as is clear from FIG.
It can be freely stored in a housing that protrudes from the housing. As is particularly clear from Fig. 6 (ω or C) and Fig. 7 (a) or C), the two types of trays All and Tray B]-2 have almost the same shape as a whole except for the following points. be.

That is, the positions of the claws 11b and 1.2b on which the operator applies his fingertips when pulling out each tray out of the magazine 5 are different, and these claws are located in the center parallel to the main surface of each tray. They are arranged in a relatively staggered manner. Because of this configuration,
When placing a finger on the claw portion 11-b of one tray, for example, tray A-1, the other tray B adjacent to the tray
The tray can be easily taken in and out of the magazine 5 without interference between the claw portions 12b of the trays 12 and the fingertips.

In addition, the ends of both trays A 1.1 and tray B 2, in this case, are formed along the disk supporting surface of each tray on an imaginary straight line passing through the center of the disk supporting surface, that is, in the shape of a rectangular plate. On or in the vicinity of a diagonal line connecting two diagonals of each tray, a plurality of tray holding arms, which are constituent members of separation and positioning means to be described later, hold two types of held portions 11c for holding each tray, respectively. and lid, and 12c and 12d are formed. As is clear from FIGS. 6(a) and (b) and FIG. 7(a) and crest), one of the two types of held portions formed on each tray, held portions 11C and 12c, is It consists of a groove formed on the end face. In addition, FIGS. 6(a) and (C) and 7
As shown in the figure (ω and (C1), the other held part 11d
1 and 2d are formed by slightly recessing both main surfaces of the tray to make the tray thinner than the other parts. 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 parts. However, such a thin wall contributes to making the magazine 5 thinner.

As is clear from the figure, the held part 11c and lid formed on tray All, and the held part 12c and 1.2 formed on the other tray B12 adjacent to tray All.
d are arranged so as to be relatively shifted in a plane parallel to the main surface of the tray.

That is, each held part 11c and 11d, and 12c
and 12d are not arranged in a straight line in the direction perpendicular to the main surface of each tray, but are staggered and dispersed from each other along the main surface of the tray. Because of this configuration, the space that must be provided in the player housing 2 for swinging of each tray holding arm (described later) for separating each tray is reduced in the direction perpendicular to the main surface of the tray, and the magazine This makes it easier to make the player smaller and thinner in this direction, and by extension, to make the player as a whole thinner.

As shown in FIG. 6(ω) to FIG. 7(C), each tray All and tray B12 has cutout portions 11f and l1g in the vicinity of the held portions 11c, lid, 12e 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 separation and positioning means (described later), and a tray adjacent to the tray held by the arm.

As is clear from FIG. 6(,1) to FIG. 7(C), the main surfaces of each tray All and tray B12 are
Circular recess 11 for accommodating and positioning the disc 9
h and 12h, and openings 11 and 12i through which a clamper to be described later can be inserted. Further, as shown in FIGS. 4 and 5, the tray holding arm of the separating and positioning means is also attached to the end of the lower half body 7 forming a part of the housing of the magazine 5, similarly to each of the trays described above. The held parts 7a and 7b held by (described later) 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-described cylindrical member 14 are provided protruding from the inner wall corner of the lower half 7 of the magazine 5. As shown in FIG. Each tray All and tray B12 is also movable in the axial direction of a cylindrical member 14 that rotatably supports them, and the cylindrical member 14 not only acts as a shaft support member that pivotally supports each tray, but also serves as a shaft supporting member for each tray. It also acts as a guide member that guides the trays so that they are aligned on a plane. One cylindrical member 14
By performing two functions in this manner, the number of parts is reduced by one compared to a configuration in which two members are provided that perform each function individually.

Note that, as described above, each tray All and tray B12 is rotated about the cylindrical member 14 to be protruded from and stored in the magazine 5. The protruding and retracting operation of the tray is not limited to rotation as described above, but a configuration in which the tray is reciprocated linearly can be considered, but 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 projecting parts 19a to 19c are protruded from the outer circumference of the movable locking member 19, and semicircular notches 19d to 19f are formed at the tips of each projecting part.
Annular grooves 14a, 16a and 1 as locked parts formed on the outer circumferential surface of the tips of the cylindrical members 14, 16 and 17 of the book.
Each of the notches 19d to 19f can be smoothly fitted into the notch 7a. For example, a cylindrical member 14 is shown in FIG.
A perspective view of a projecting portion 19a that engages with the projecting portion 19a is shown. In addition,
The same holds true for the relationships between the other two cylindrical members 16 and 17 and the overhanging portions 19b and 19c. That is, the movable locking member 19 provided on the upper half body 6 is attached to each of the annular grooves 14a, rollers a and 17a of the three cylindrical members 14, 16 and 17 fixed on the lower half body 7. Each notch 19d to 19f
By fitting, the upper half 6 and lower half 7 are fixed to each other, and when the fitted state is released, the two halves can be separated. Note that each notch 19d to 1.9f is connected to each annular groove 14a, 16.
The position of the movable locking member 19 in a state where the movable locking member 19 is fitted into the holes 17a and 17a is referred to as the locking position, and the movable locking member 19 is released from this fitting.
The position 9 is called the non-latching position.

As shown in FIG.
7, one projecting portion 19c of the movable locking member 19
By engaging with the notches 19d to 19f of each of the protruding parts 19a to 19c, the direction is directed in the direction of fitting into the annular grooves 14a, 16a, and 17a of each cylindrical member 14.16 and 17 (in the direction of arrow G). A biasing lever 21 for biasing the movable locking member 19 is swingably provided via a support pin 21a. Further, a spring member 22 that applies a biasing force to the biasing lever 21 is fitted into the support bin 2]8a. These biasing levers 21 and spring members 22
This constitutes a biasing means for biasing the movable locking member 9 toward the above-mentioned locking position. This urging means, the above-mentioned movable locking member 19, and three cylindrical members 14, 1 as locked portions that are engaged with the movable locking member.
．． 6 and 1-7 constitute a locking mechanism that fixes the upper half body 6 and the lower half body 7 to each other.

By providing such a locking mechanism, when an operator handles the magazine 5 to load or replace a disk in the magazine 5, the locking mechanism is activated to secure the upper half body 6 and the lower half body 7 to each other. By doing so, 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, and the magazine 5 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, and various other configurations may be used, such as a swingable arm shape or a lever shape that can 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 within the player housing 2. As shown in FIGS. 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. The notches 6a, 6b, 7d, llj, llk, 12j and 1
2k is formed. Note that, regarding the lower half 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 25 are provided in the player housing 2 so as to fit into two longitudinal grooves formed by each of these notches.
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 2
Reference numeral 5 denotes a device that slides on the trays All and B12 and the lower half body 7 that are to be separated from each other as will be described later, and guides them in the separation direction. As shown in a perspective view of one of the guide shafts 24 in FIG. 13, flanges 24a and 25a are formed near the upper ends of both guide shafts 24 and 25, forming the upper half of the housing of the magazine 5. By fitting the notches 6a and 6b of the upper half body 6 into the upper end portions of the guide shafts 24 and 25, the upper half body 6 is supported by both the flanges 24B and 25a, and the upper half body 6 is moved downward. is regulated. Note that, as mentioned above, one guide shaft 25 is connected to the player housing 2.
In contrast, the other guide shaft 24 projects onto the free end of a lever member 26 that is swingably provided to the player housing 2 via a support pin 26a. The spring member 2
7 in a direction toward the magazine 5. Therefore, this guide shaft 24 is connected to the magazine 5.
As the magazine 5 is inserted into the player housing 2, the lever member 26 is retracted by swinging clockwise in FIG. At the same time as the insertion is completed, the lever member 26 is returned by the biasing force of the spring member 27, thereby fitting into each notch of the magazine 5.

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 or the player housing 2 is installed as described above, The guide shaft 25 is in a state of pushing this overhang 19g. As a result, the movable locking member 9 is rotated counterclockwise in the drawing, and each of the protruding portions 19a to 19c of the movable locking member 19 is rotated to the 3 which they were locked.
The book is separated from the cylindrical members 14, 16 and 17, the upper half 6 and the lower half 7 are no longer fixed, 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.

A performance means including a turntable is mounted nearby and the performance is started.

Here, the above separation and positioning means will be explained in more detail.

First, as described above, the separating and positioning means has two cam members and two groups of six tray holding arms each driven by the two cam members 30, and each tray of the magazine 5 is connected to both tray holding arm groups. The held portions 11e and 11d are formed along the disk supporting surface on the virtual straight line passing through the center of the disk supporting surface or at the ends of the virtual straight line passing through the center of the disk supporting surface.
, 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 the 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 positions near the diagonal line thereof, thereby supporting 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 tilt regulating means, the tray is always moved in parallel without tilting, so that the disc on the tray does not shift due to the tray tilt.
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 FIGS. 9 and 11, six tray holding arms 43 to 48, which are one group of tray holding arms arranged at the rear of the magazine 5, alternately hold two different virtual planes. They are arranged so that they swing along the That is, the six tray holding arms are alternately divided into two subgroups, in this case tray holding arm 4.
3. 45 and 47 are made into one small group, and the remaining three tray holding arms 44, 46 and 48 are divided into another small group, and the virtual planes along which the tray holding arm groups of both small groups should be moved are mutually horizontal planes. It is shifted within. 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 both sets are accurately guided, and are prevented from interfering with the tray holding arm group of the other set 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 of the tray holding arms is not limited to the swing as described above, but various other movements such as parallel movement can be considered. 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;
The swinging position indicated by the two-dot chain line in the figure is the non-insertion position. 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 support 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 is slidably supported by a guide shaft 101 at the other end. However, the second
The guide shaft 101 and the worm 102 are not shown in the figure.

The carriage 103 houses an optical pickup including an objective lens 105 (shown in FIG. 9). This optical pickup is similar to a known one and will not be described in detail, but it includes a servo mechanism 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. Further, as shown in FIGS. 9 and 16, the guide shaft 101 for guiding the carriage 103 is disposed within another elongated opening 98b formed in the movable carrier member 98, and the guide shaft 101 is arranged in another elongated opening 98b formed in the movable carrier member 98. It is used as an installation space. Therefore,
The space that the guide shaft 101 should occupy is reduced, contributing to the downsizing of the player.

As shown in FIGS. 9 and 16, the above-mentioned worm 10
A plurality of pulleys and hooks thereof are rotated by a motor 08 disposed on the proximal end side of the movable support member 98.
A power transmission mechanism consisting of a main belt is rotated by applying torque through the belt. 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,
Near this detection switch 111, a photo sensor] 12
is provided. As shown in FIG. 9 and FIGS. 1 and 2, when the movable support member 98 is in the non-inserted position, the photosensor 112 can detect the
An address plate 113 having two slits 113a arranged vertically is attached to the left inner wall surface of the player housing 2.

The guide shaft 101 described above, the worm 102,
The motor 108, the power transmission mechanism 109, and the detection switch 111 constitute a pickup guide drive means for guiding and moving 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 115 swings in a plane including the vertical direction.

The swinging end of the clamper arm 115 is provided with a pressing member 117 that presses the disc 9 to be played toward the disc supporting surface of the turntable 100 via a clamper or a spherical bearing 118 (shown in FIG. 16). It is rotatably mounted.

The above-described clamper arm 115 and 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]00, the optical pickup including the carriage 103, and the pickup guide drive means consisting of the guide shaft]01, the worm 102, the motor 108, 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 shows the xv-xv arrow view in FIG. Motors 121 and 12 are provided at the front and rear of the shaft 95, respectively.
2 are arranged.

A motor 21 provided at the rear of the support shaft 95 is for moving the movable support member 98 along the support shaft 95, and a motor 122 provided at the front is for swinging the movable support member 98. It's a motor.

As will be described later, the motor 122 also applies driving force to the disk clamp/clamp groove.

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 screw 123, and the torque from the motor 121- is transmitted to this gear through the gear] 24, 125a, worm wheel] 25b1, worm 126, gears 127 and 128. ]-23a 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 130a is protruded from the upper end of the cylindrical member, and is formed on the movable support member 98. This pin 130a is inserted through the circular opening 98f with a predetermined gap. A gear 130b is integrally formed at the lower end of the cylindrical member 130.
2, Face gear] 33, Worm] 34, Worm wheel 1.35a, Gear 135b, Gears 136 and 13
7, the torque from the motor 122 is transmitted to the 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, and as shown in FIG. A pin 137a protruding from the upper stop surface of the lower gear 137 is slidably fitted into the groove 1368.

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 140 is fitted therein as a means for imparting a high aperture for applying a high aperture.

The above motors 121 and 122 and gears 123a and 1
24 and 125a, worm wheel 125b, worm 126, gears 127 and 128, and pin 130
a, gears 130b and 132, and face gear 1-3
3, the worm 134, the worm wheel 135a, and the gear 1.35b.

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 is controlled by the support member driving means, the movable support member 98, the support shaft 95, the above-mentioned M positioning means, and the spring member 140 that provides the movable support member 98 with a bias.
A playing means transporting mechanism is constructed for moving the above-mentioned playing means such as 00 and attaching it to the disc to be played.

Note that, as described above, the movable support member 98 is configured to swing, or 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. . 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 FIG. 9, FIG. 16, and FIG.
2a (shown in FIG. 16), it is swingably mounted at its central portion in a horizontal plane. A cam portion ]-36b 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, and the intermediate lever 1
The cam surface of the cam portion can slide into a hanging portion 142b (the reference numeral is shown only in FIG. 16) formed at one swinging end of the cam portion 42. 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 or a clamper arm 1 which is a component of the disk clamp mechanism.
It is brought into contact with a hanging portion 115a formed in 15. 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 pivots around the screw] 42a,
A protrusion 142 formed on the other swinging end of the intermediate lever 142
c pushes the hanging portion 115a of the clamper arm 115, and the disc is 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
U150 operates RAM 153 according to a control program stored in advance in ROM 151 in response to signals from a keyboard 152 consisting of a photosensor 84, 112, a detection switch 111, and a switch group (not shown).
It issues commands to the motors 32, 108, 121 and 122, as well as the turntable 100 and pickup 155.

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 tenth subroutine (step S3) shown in FIGS. 19 and 20. In addition, this 1st. When the loading subroutine is executed, the magazine 5 is only inserted into the player housing 2, and the lower half 7 and upper half 6 of the magazine 5 have not yet been separated.

A movable locking member 1 is inserted into the player housing 2 by the operator to fix the lower halves 6 and 7 of the magazine 5 to each other.
The guide shaft 25 shown in FIG. 9 pushes one of the projecting portions 19g by the reaction force of this mounting force. As a result, the movable locking member 19 is rotated counterclockwise in FIG. 2 and FIG. It separates from the phase members 14, 16 and 17, the fixed state between the upper half 6 and the lower half 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] 00 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 12 to the state shown in FIG. 22. As a result, the lower half 7 of the magazine 5 is moved downward and the upper half 6
separated from Furthermore, as shown in FIG. 22, at the same time as the lower half body 7 and the upper flat body 6 are separated, the lowest tray All of the five trays housed in the magazine 5 is separated from the other trays. and brought to a position corresponding to the playing means including the turntable 100.

Among the five trays arranged, if the disk containing the designated track is carried on the third tray A11 from the bottom, the motor 32 is further rotated in the normal direction (step S5), and both cams are rotated in the forward direction. Members 29 and 30 are synchronously moved to a further 6
It is rotated in the normal direction by 0°, from the state shown in FIG. 22 to the state shown in FIG. 23, and then to the state shown in FIG. 24, and the tray A 1.1- carrying the desired disk is separated from the other trays. Further, along with this tray separation operation, the motor 121 is caused to rotate forward (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 lifting distance of the movable support member 98 are determined by the two photosensors 8 described above.
The control unit counts the number of slits 83a, 13a of each of the address plates 83 and 113 detected by the address plates 83 and 112 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.

If the address of the current disk matches the address of the search disk (step S6), the motor 32 and the motor]
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 support member 98 is transmitted through the gear 132 and the face gear 133.
, worm 134, worm wheel 135a, gear 1
35b and 136, bin 137a1 gear 137 and 1.
30 b , are applied to the movable carrier member 98 via the cylindrical member 130 and the pin 130a in sequence. motor 122
Before the gear 1 starts normal rotation, the gear 1 is slidably fitted into the arc-shaped groove 136a formed on the lower stop surface of the gear 136.
The bottle 137a installed on the upper ball surface of the lens 37 has a positional relationship as 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] 37 rotate synchronously while maintaining the relative positional relationship between the arcuate groove 136a provided therein and the bottle 137a as shown in FIG. That is, the spring member 140
The swinging of the movable support member 98 due to the biasing force of the motor 12
The rotation of 2 allows it to be performed. 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 carrier member 98, thereby causing it to rotate relative to the gear 136 or the other gear 137 which is in the fixed state. As mentioned above, the cam portion 136 is located on the upper stop surface of this gear 136.
Since b is integrally formed, as the gear 136 rotates, the cam portion 136b comes into sliding contact with the intermediate lever 42, as shown in FIG. 27, causing it to swing. As a result, the hanging portion 115 of the clamper arm 115 shown in FIG.
a 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, moves the disk 9. Push it up to 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,
As a result, the maximum diameter part of the cam part 136b and the intermediate lever 1
42 are prevented from interfering with each other. Also,
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. (Step 5IO). 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 forward direction (step 51).
In step 1), the carriage with a built-in pickup] 03 starts moving, and the performance begins.

After confirming that the performance of the first disc has ended (step 512), the control unit stops the forward rotation of the carriage transport motor 108 and stops the pickup operation, and immediately reverses the motor 108. (Step 81
3). 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, the protrusion formed on the carriage 103 reaches the ninth position.
It engages with the actuator 111a of the detection switch 111 shown in the figure to operate the detection switch. Based on the detection signal emitted from the detection switch 1.11, the control unit recognizes that the carriage 103 has come closest to the turntable 100 (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 expose 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 (step 517), and controls the motor 122.
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 size of the player can be reduced. Since the player housing 2 is normally formed in the shape of a rectangular parallelepiped as shown in the embodiment, and the disk accommodated therein is circular, relatively large spaces are formed at the four corners inside the player housing 2. Therefore, if the movable longitudinal support member 98 is configured to be located close to and along the inner wall surface of the player housing 2 when the longitudinal movable support member 98 is in the non-opposed position, the ends of the movable support member 98 The section 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. This increases the space utilization efficiency inside the player housing 2, 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). Then, if the tray carrying the second designated disk among the five trays arranged is the tray A11 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 forward by 60°, and the second
The state shown in FIG. 4 is changed to the state shown in FIG. 25 through the state shown in FIG. 26, and the tray All in the uppermost position is separated from the other trays. 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 for two trays from the position determined in the above-mentioned 10th-daying subroutine. It is raised by a distance corresponding to the thickness and positioned at a position corresponding to the lowest tray A11 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, in conjunction with this tray separation operation, the motor 12 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 dewing 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 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 the free end of each of the tray holding arms 43 to 48 and 73 to 78, which holds the tray separated from the other tray groups. One half is oriented 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 100
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 is composed of a pair of upper halves that can be separated from each other, and a housing. and a plurality of plate-shaped trays, each of which can support a disc on its main surface and which can be protruded from the housing along each main surface and can be housed therein. separation and positioning means for separating the discs, selecting a tray carrying a desired disk from among the trays, holding it, separating it from other trays in a direction perpendicular to the main surface of the tray, and positioning it; The turntable, pickup, and disk clamp mechanism are movable between an insertion position and a non-insertion position in which the trays can be inserted in a direction substantially perpendicular to the tray separation direction, and are movable in the separation direction. a movable support member carrying a playing means, and a support member drive means for appropriately moving the movable support member in each of the above directions, and the tray carrying the disc to be played is separated from other trays by the separation positioning means. After the disc is separated, the movable supporting member is inserted between the trays, the playing means is attached to the disc, and the disc is clamped by the disc clamp mechanism, and the pickup is activated to start playing. There is.

Because of this configuration, the space that must be provided within the player/%Using for mounting the playing means on the disc to be played is extremely small, and the overall size of the player can be reduced. It can also be used by being stored in the space formed in the dash board.

Further, in the multi-disk storage player according to the present invention, the separating and positioning means includes a plurality of tray holding members that are provided movably in the separating direction and hold end portions of the trays, and a plurality of tray holding members that move the tray holding members. The tray holding member holds the tray on or near a straight line passing through the center of the disk holding surface along the disk holding surface of the tray.

In such a configuration, when the magazine is in the shape of a rectangular parallelepiped and the tray is in the shape of a rectangle, as in the embodiment, the tray holding member holds the tray on its diagonal; The holding member driving means can be efficiently disposed in the inner part of the player housing, increasing the space utilization efficiency inside the play housing, and further downsizing the player as a whole.

In addition, as described above, by holding the trays diagonally, the amount of deflection of the trays can be minimized, and the distance between the separated trays will not be narrowed due to deflection or inclination of the trays. The disc can always be inserted smoothly between the trays, and the playing means can be attached to the disc reliably and smoothly.
