Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to front loading disc players.

Background Art A front-loading disc player has an insertion slot formed in the front panel of a player housing, through which an information recording disc (hereinafter simply referred to as a disc) is fed and brought to a playing position. This makes it possible to place objects on top of the player.

Various types of front-loading disc players have been developed, such as Japanese Patent Application Laid-Open No. 61-80554.
As disclosed in the above publication, a long and narrow slot is formed in the front panel portion as an insertion slot, and the disc inserted through this slot is inserted in a direction parallel to the main surface of the disc and in the same direction. There is a slot-in type that is transported in a direction perpendicular to the turntable and mounted on the turntable. Also, JP-A-62-2917
As disclosed in Japanese Patent Application No. 48, etc., the carrier has a carrier that can be protruded and stored through a rectangular opening formed in the front panel, and a disc is carried on the carrier that protrudes outside the player housing. There is a carrier protruding housing type in which the disc is mounted on a turntable by moving the disc in two directions, horizontal and vertical. Also, JP-A-64-52250
As disclosed in the above publication, a magazine containing a plurality of discs arranged in an array is removably inserted into the mounting part in the player housing through the insertion opening in the front panel part, and any discs in the magazine are sequentially inserted. A disc ejecting and transporting mechanism is provided to select and transport a plurality of discs onto a turntable in two directions, one parallel to the main surface of the disc and one perpendicular to the main surface, and a plurality of discs can be played continuously. There are also players that can store multiple discs.

As mentioned above, in conventional front-loading disc players, a large area of the disc is moved in order to load the desired disc onto the turntable, so a large space is required inside the player housing for the movement of the disc. This makes it difficult to downsize the player.

Incidentally, there has recently been a desire to develop a front-loading disc 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 points, and its object is to provide an extremely compact front-loading disc player.

[Structure of the Invention] A front loading disc player according to the present invention includes a playing means provided in a player housing including a turntable, a pickup, and a disc clamp mechanism, and a disc inserted through an insertion opening formed in the player housing. and a performance means transport mechanism for moving the performance means and mounting it on the disc, the performance means transport mechanism being swingably provided parallel to the recording surface of the FJ disc. a movable support member that supports the playing means, and a support member driving means for swinging the movable support member, and the center of swing of the movable support member is located at the insertion point beyond the disc holding position by the disc holding means. It is placed close to the mouth.

Effects of the Invention C: In the front loading disc player having such a configuration, when a performance command is issued while the disc to be played is held by the disc holding means, the movable supporting member is caused to swing and the turntable is rotated. The playing means including the disc is mounted on the disc, and then the disc is clamped by the disc clamp mechanism, the pickup is activated, and playing begins.

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 B12 each capable of supporting a disk 9 on its main surface.
It has 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.

There are three trays A], 1 and two trays B12, and these are arranged alternately. Tray All and tray B12 have a circular hole 1 in one corner.
1a and 12a, and as shown in FIG. 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. 3, each tray can rotate around this cylindrical member 14, and can thereby be protruded and stored in the housing consisting of the upper half body 6 and the lower half body 7. . Figure 6 (■ or C) and Figure 7 (a) or C)
However, as is particularly clear, the two types of trays All and B12 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 the trays 12b 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(a) and +tn and FIG. 7 (J and mountain), one of the two types of held portions 11 formed on each tray
c and 12 C consist of grooves formed on the end face of the tray. In addition, as shown in FIG. 6 (C1 and FIG. 7(a) and <C), the other held part lid and 12d
The tray is made by slightly recessing the two sides of the tray to make it thinner than the other parts. Note that these held parts 11. d
And 12d may not be made thin, but may be formed to have the same thickness as the other parts. However, by making it thin like this,
This contributes to making the magazine 5 thinner.

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

That is, each held part 11c and lld, 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 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.

As shown in FIG. 6(ω) to FIG. 7(C), each tray A unit 1 and tray B 12 has a cutout portion 11f in the vicinity of each of the held portions lie, lld, 12c and 12d. , l1g, 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.

Furthermore, as is clear from Fig. 6 (ω to Fig. 7 (C)),
, the main surfaces of each tray All and tray B12 have circular recesses 11h and 12h for accommodating and positioning the disk 9, and an opening 11 through which a clamper, which will be described later, can be inserted.
i and 12i are provided. Also, Figures 4 and 5
As shown in the figure, the end of the lower half 7 forming a part of the housing of the magazine 5 is also covered with a cover held by a tray holding arm (described later) of the separation and positioning means, similar to the above-mentioned trays. The holding parts 7a and 7b 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.

Incidentally, as described above, each tray All and tray B12 is rotated about the cylindrical member]4 to be projected into 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 disk-shaped and annular movable locking member 19 is rotatably attached to the inner wall surface of the upper half 6 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 1.9d to 19f can be smoothly fitted into the notch 7a. 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 other two cylindrical members 16 and 17 and the overhang portion 19b
The relationship with 19c is also similar. That is, lower body 7
For each of the annular grooves 14a, 16a and 17a of the three cylindrical members 14[deg.]6 and 17, each notch 19d to 1 of the movable locking member 19 provided on the upper half 6
By fitting the upper half 6 and the lower half 7, the upper half 6 and the 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 19f is connected to each annular groove 14a, 16.
The position of the movable locking member 19 in a state where it is fitted to the holes a and 17a is referred to as the locking position, and the movable locking member is released from this fitting.]
The position 9 is called the non-latching position.

As shown in FIG.
In the vicinity of 7, one projecting portion 19c of the movable locking member] 9 is provided.
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 pin 21a. The biasing lever 21 and the spring member 22 constitute a biasing means for biasing the movable locking member 19 toward the above-mentioned locking position. The upper half body 6 and a locking mechanism for fixing 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 can be 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 one movable locking member 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; 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 playing means transport mechanism that moves the playing means including a turntable, a pickup, and a dice clamp mechanism, and loads the playing means onto 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. At the ends and side ends of each of the lower half body 6 and the lower body 7 constituting the magazine 5, as well as the trays All and B12 in the magazine insertion direction, there are arranged in a straight line in the arrangement direction of the trays as a whole. Notches 6a, 6b, 7d, llj, llk, 12j and 1 are formed to form two grooves.
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 2 are provided in the player nose leg 2 so as to fit into 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, tray B12 and lower half body 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. 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. The notches 6a and 6b of the upper half body 6 fit into the upper end portions of the guide shafts 24 and 25, so that the upper half body 6 is supported by both the flanges 24a and 25a, and the upper half body 6 is moved downward. is regulated. 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 5 as it is inserted into the player housing 2. When the insertion of the magazine is completed, the lever member 26 returns to its original position under 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, one disc-shaped movable locking member that fixes 17 the upper half 6 and lower half 7 of the magazine 5 to each other has three Another projecting part 19g is integrally formed near one of the projecting parts 19a to 19c, and when the magazine 5 is installed in the player housing 2 as described above, The above-mentioned guide shaft 25 is now in a state of pushing this overhanging portion 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 is locked with the 3
The book is separated from the cylindrical members 14, 16 and 17, the upper body 6 and the lower body 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.

First, the separation positioning means forming a part of the performance means conveying mechanism will be explained.

As shown in FIGS. 9, 11, and 12, two disc-shaped movable cam members 29 and 30 are located within the player housing 2, respectively, to the rear and right sides of the mounted magazine 5. , is arranged so that its main surface extends in the vertical direction (arrow Z direction and the opposite direction) from which the upper half body 6, the lower half body 7, and each tray are to be separated;
Moreover, it is rotatably attached to the player housing 2. The outer circumferential surfaces of both of the cam members are worm wheels to which torque is applied via the gears described below. As clearly shown in FIG. 14, six cam grooves 30a to 30f are formed on the main surface of the cam member 30. Further, the other cam member 29 is formed to have a completely symmetrical shape to the one cam member 30,
As is clear from FIG. 12, six cam grooves similar to the valley grooves of the cam member 30 are formed on its main surface. In addition,
By making the cam members 29 and 30 thin and disc-shaped in this way, the space they occupy is reduced, the efficiency of space utilization within the player housing is increased, and the player can be made more compact.

As shown in FIG. 9, the above two cam members 29 and 3
A motor 32 is disposed deep within the player housing 2 so as to be located between 0 and 0. As shown in FIG. 12, one of the cam members 29 is rotated by being applied with torque by the motor 32 through the gears 32a, 33, 34, and 35, and the worm 36. Further, as shown in FIG. 11, the other cam member 30 has gears 32a and 3.
Torque from the motor 32 is transmitted sequentially through 3.37 and 38 and the worm 39. Both cam members 29 and 30 are driven synchronously and at the same rotational speed by the torque applying means.

As shown in FIGS. 9 and 11, a flat plate-shaped bracket 41 extending in the vertical direction is provided between one cam member 30 and the magazine 5 (however, in FIG. 41 is not shown), this bracket 4
], the six tray holding arms 43 to 48 as tray holding members are moved at one end thereof through the support bins 43a to 48a in the vertical direction, that is, in the direction in which the lower half 7 of the magazine 5 and each tray are to be separated. It is attached so that it can swing freely. As shown in FIG. 11, at the other end of each of these tray holding arms 43 to 48, pivot pins 43b to 48b are attached to the support pins 43H.
It is planted parallel to 48a. Six slide pieces 61 to 66 are provided near each of the pivot pins and are slidably guided by seven guide shafts 51 to 57, which are respectively provided to extend in the vertical direction. Each of the pivot pins is pivotally connected to each of the slide pieces. For details, refer to each slide frame 61 to 6.
An oval groove extending horizontally is formed on the side surface of the holder 6, and each pivot pin is slidably engaged with this groove. Of these six slide pieces, the top five slide pieces 61 to 65 each have a thin-walled held portion lid and 1.2 d formed on each tray All and tray 1'B 12 in the magazine 5. keeping.

Further, the remaining slide piece 66 holds a held portion 7b formed as a thin wall portion in the lower half 7 of the magazine 5.

Then, the above six tray holding arms 43 to 48
Sliding pins 43e to 48c as cam followers are implanted in parallel to the support pins 43a to 48a and the pivot pins 43b to 48b, respectively, in the central part of the slide pins 43e to 48c. It is slidably engaged with each of the cam grooves 30a to 30f of the cam member 30 shown in the figure. That is, the rotation of the cam member 30 based on the rotation of the motor 32 causes each of the tray holding arms 43 to 4 to
8 can be inserted as appropriate. Note that the timing of swinging of each tray holding arm will be described in detail in the section of explanation of operation described later.

As shown in FIGS. 9 and 12, a flat bracket 71 is provided between the other cam member 29 and the magazine 5 so as to extend in the vertical direction. Tray holding arms 73 to 78 as holding members are attached to one end thereof via support bins 73a to 78a so as to be able to vibrate in the vertical direction. As shown in FIG. 12, pivot pins 73b to 78b are implanted at the other end of each of the tray holding arms 73 to 78 in parallel with the support pins 73a to 78a. Of these six pivot bins, the top five pivot bins 73b to 77b are smoothly engaged with the oval grooves that are the held parts lie and 12c formed on each tray A11 and tray B12. It matches. Further, a slide piece 81 is provided near the remaining one pivot pin 78b, and is slidable along a guide shaft 80 provided to extend in the vertical direction. It is pivoted to 81. Specifically, an oval groove extending horizontally is formed on the side surface of the slide piece 81, and the pivot pin 78b
is slidably engaged in this groove. and,
This slide piece 81 holds a held portion 7a formed as a thin wall portion in the lower half 7 of the magazine 5.

Sliding bins 73c to 78c as cam followers are installed in the central portions of the six tray holding arms 73 to 78 in parallel with the supporting bins 73a to 78a and pivot bins 73b to 78b, respectively. The tip of each sliding bottle is formed on the main surface of the cam member 29.
They are each slidably engaged with the cam grooves of the strips. That is,
Due to the rotation of the cam member 29 based on the rotation of the motor 32,
Each of the tray holding arms 73 to 78 is configured to swing in synchronization with the other tray holding arms 43 to 48 described above.

As shown in FIGS. 9 and 12, an address plate 83 formed in an arc shape is fixed concentrically to the cam member 29 on the opposite side of the cam surface. Six slits 83a are formed in the address plate 83, with one pitch corresponding to the rotation angle 30'' of the cam member 29.A photosensor 84 is provided to detect the slits, and The address plate 83 and the photosensor 84 are fixed to the player housing 2. The address plate 83 and the photosensor 84 control the rotation angle positions of both the cam members 29 and 30, that is, the swing positions of the tray holding arms 43 to 48 and 73 to 78. It is for detection.

The above motor 32, gears 32a, 33, 34, 35
．． 37 and 38 and worms 36 and 39,
A driving force applying means for applying driving force to both cam members 29 and 30 is configured. The driving force applying means and both cam members 29 and 30 constitute a holding arm driving means, that is, a holding member driving means for swinging each tray holding arm 43 to 48 and 73 to 78. Further, the holding arm driving means and each tray holding arm separate the upper half 6 and lower half 7 of the magazine 5, and select a tray carrying a desired disk from among the trays accommodated therein. Separation and positioning means is configured to select and position the tray by separating it from other trays in a direction perpendicular to the main surface of the tray.

Note that this separating and positioning means is also referred to as disk holding means. That is, the disc to be played, along with the tray carrying the disc, is separated from other trays and positioned and held at a predetermined position by the separating and positioning means, and the disc in this position is moved as described below.
Performance means including a turntable are mounted nearby and the performance begins.

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

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 lie, lid 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.
, 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 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 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 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 move along two different virtual planes. They are arranged so that they can oscillate. 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. They even do it within themselves. 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
In addition, the tray holding arms 73 to 78 are each configured to swing, and the movement of each of the tray holding arms is not limited to swinging 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 carrier member 98, which is shown in dashed lines in FIG. 2 and shown in solid lines in FIG.
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 10] 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 onto the worm 102. and 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 has a built-in optical pickup 17 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. 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
2 is a motor 108 disposed on the proximal end side of the movable support member 98, and a plurality of boars and hooks thereon are rotated.
Torque is applied through a power transmission mechanism 109 consisting of a book belt to rotate it. 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.
Detection switches 1 and 11 are 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 FIGS. 9 and 12, five slits 113a that can be detected by the photosensor 112 when the movable support member 98 is in the above-mentioned non-insertion position are arranged in an address in the vertical direction. A plate 113 is attached to the left inner wall surface of the player clamp 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 that guides and moves the carriage 103 carrying the pickup knob toward and away from the turntable 100. .

As shown in FIGS. 2 and 16, a clamper arm 115 is arranged 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 1]6 is swingably attached to the hanging portion 98d at one end thereof. The clamper arm 115 swings in a plane including the vertical direction.

A pressing member 117, that is, a clamper, which presses the disc 9 to be played toward the disc supporting surface of the turntable 100 is attached to the swinging end of the clamper arm 115 via 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 disc 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 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 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 internal thread 23, with gears 124, 125a, worm wheel 125b, worm 126, and gear 127.
Torque from the motor 121 is transmitted to the gear 123a and the female screw 123 through the gears 123a and 128 in sequence.

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.
The bottle 130a is inserted through a circular opening 98f with a predetermined gap. A gear 130b is integrally formed at the lower end of the cylindrical member 130, including a gear core 32, a face gear 133, a worm 134, a worm wheel 135a, a gear 135b, gears 136 and 1.
37, the torque from the motor 122 is transmitted to the gear 130b and the cylindrical member 130. In addition,
The gears 136 and 137 are not integral with each other, but are both concentrically supported by 13 shafts, and as shown in FIG. 17, an arcuate groove 136a is formed in the lower main surface of the upper gear 36 On the other hand, a pin 137a protruding from the upper stop surface of the lower gear 137 is slidably fitted.

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 bias spacing applying means for imparting a bias spacing towards the target.

The above motors 121 and 122 and gears 123a and 1
24 and 125a, worm wheel 125b, worm 126, gears 127 and] 28, and bin 130
a, gears 130b and 132, and face gear] 33
, a worm 134, a worm wheel 135a,
Gear Co., 35b.

136 and 137 and the bottle 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 separation and positioning means, and the spring member 140 that provides the movable support member 98 with a bias.
A playing means conveying mechanism is constructed for moving the above-mentioned playing means such as 00 and attaching 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 supporting member 98 is swingably attached to the support shaft 95 so as 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 is attached to a screw 14 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] 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.
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. As shown in FIG. 16, the intermediate lever 14
A hanging portion 142b is also formed at the other swinging end of No. 2,
A protrusion 142C protruding from this hanging portion 142b is connected to the clamper arm 11, which is a component of the disk clamp mechanism.
It is brought into contact with a hanging portion 115a formed in 5. That is, the cam portion 136b integrated with the gear 136 is rotated by the power applied from the motor 122,
The cam surface of the cam portion contacts and presses one hanging portion of the intermediate lever 142, so that the intermediate lever 142
A protrusion 142C is formed on the other swinging end of the intermediate lever 142 and swings around a lever 142a that pivots thereon.
is configured to press the hanging portion 115a of the clamper arm 115, thereby clamping the disk.

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, the turntable 100 and the pickup] 55 in cooperation with the controller.

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 emitted by a magazine detection means (not shown) (steer knob 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. Note that when this tenth loading subroutine is executed, 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 when the magazine 5 is inserted into the player housing 2 by the operator, a movable locking member 1 fixes the upper half 6 and the lower half 7 of the magazine 5 to each other.
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. 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. 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, 300, 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 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 tongue table 100.

If the disk containing the designated track is carried on the third tray A11 from the bottom among the five trays arranged, 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
0'' normal rotation, the state shown in FIG. 22 passes through the state shown in FIG. 23, and the state shown in FIG. 24 is reached, and the tray All carrying the desired disk is separated from the other trays. Accordingly, the motor 12 is rotated in the forward 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 rotation angle 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 without 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), 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 support member 98 is transmitted through the gear 132 and the face gear 133.
, worm], 34, worm wheel 135a, gears 135b and 136, bin 137a1 gears 137 and 1
30b, the cylindrical member 130 and the vial 130a in turn to the movable carrier member 98. Before the motor 122 starts normal rotation, the gear 137 is slidably fitted into the arcuate groove 136a formed on the lower stop surface of the gear 136.
The pin 137a implanted in the top stop surface 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 two gears 136 and 137 rotate synchronously while maintaining the relative positional relationship between the arc-shaped groove 136a and the pin 137a provided therein as shown in FIG. 17. In other words, the movable support member 98 is oscillated by the biasing force of the spring member 140 or is allowed to swing by 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 of finger movement 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 end surface of this gear] 36.
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. 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, and 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, the number of 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).
1) The carriage 103 containing the pickup 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 512). 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.
The detection switch shown in the figure] is engaged with the actuator 111a of the detection switch 11 to operate the detection switch. Based on the detection signal emitted from the detection switch 111, the control unit recognizes that the carriage 103 has come closest to the turntable 100 (step 514), and accordingly controls the motor 10.
8 and the gear ridge 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 the disk accommodated therein is circular, so relatively large spaces are formed at the four corners inside the player housing 2. Ru. 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, the carriage 103 can be This increases the space utilization efficiency within 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 holding the second specified disk among the five trays arranged in the array is the tray A1.1 at the top position, the control unit rotates the motor 32 in the forward direction (step 823 ) to further rotate the two cam members 29 and 30 in the normal direction by 60'',
The state shown in FIG. 24 is changed to the state shown in FIG. 25 to 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 32B), and the movable support member 98 carrying the playing means is moved from the position determined in the above-mentioned 10th-daying subroutine for two trays. It is raised by a distance corresponding to the thickness, and positioned at a position corresponding to the two lowest trays 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 121 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 motor 121 are stopped (step 526). Step S in the 10th-Ding subroutine of
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 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 front-loading disc player according to the present invention, the turntable, pickup, etc. A movable support member carrying a playing means consisting of a disk clamp mechanism and a disk clamping mechanism is swung parallel to the recording surface of the disk, and the playing means is mounted.

Due to this construction, the space that must be provided in the player housing for mounting the playing means with respect to the disc to be played is sufficient to allow the swinging of the movable carrier member, which has a considerably small area compared to the disc. As a result, the player as a whole can be miniaturized, and can be used, for example, in a vehicle by being stored in a space formed in a dash board of a vehicle.

Further, in the front loading disc player according to the present invention, the center of swing of the movable support member is located closer to the insertion slot than the disc holding position by the disc holding means. By arranging the center of swing of the movable support member at such a position, a relatively large space is formed in the center and deep part of the player housing, and the support member driving means and other mechanisms for moving the movable support member can be easily accommodated. This space can be used as an occupied space, increasing the degree of freedom in selecting the installation position of the mechanism inside the player, and making it easier to further downsize the player.
