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

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

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

By providing such tray tilt restricting means, the tray can always be moved in parallel without tilting. Therefore, the disk on the tray does not shift due to the tilting of the tray, and the disk of the playing means including a turntable described later does not move. The mounting is always reliable and smooth.

Incidentally, as a driving force applying means for applying a driving force to each tray holding arm 73 to 78 as the above-mentioned tray tilt restricting means, to each tray holding arm 43 to 48 which exclusively controls the separating operation of each tray. Motor that gives driving force
Since 32 is also used, there is no need to specially provide a driving force applying means dedicated to the tray tilt regulating means, and the reduction of the driving source is achieved.

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

Further, as shown in FIG. 9, the tray holding arms 43, 45 and 47 as one small set and the tray holding arms 44, 46 which are the other small set are arranged so as to be offset from each other in the horizontal plane as described above. A partition member 88 is interposed between the partition member 48 and 48. The partition member 88 accurately guides the tray holding arm groups of both the small sets, prevents the tray holding arm groups of the other set from interfering with each other due to distortion or the like, and operates smoothly.

On the other hand, as is clear from FIGS. 9 and 12, the magazine 5
Six tray holding arms 73 to 78 arranged at the rear of the
Similarly, the tray holding arms 43 to 48 are alternately divided into two small sets, and these two small sets are arranged so as to be displaced in a horizontal plane, and a partition member 89 is provided between them.

As described above, the tray holding arms 43 to 48 and 73 to 78 are configured to swing, respectively. However, the movement of the tray holding arms is not limited to such swinging, but may be parallel movement, for example. There are various other possibilities. However, by adopting such a swinging structure, the operation of each tray holding arm is always reliably and smoothly performed.

Next, a mechanism that constitutes the above-described performance means transport mechanism together with the above-described separation positioning means will be described.

On the other hand, a cylindrical member 130 is rotatably fitted on the female screw 123, and a cylindrical pin 130a is projectingly provided on the upper end of the cylindrical member and formed on the movable carrying member 98. The pin 130a is inserted through the circular opening 98f with a predetermined gap. A gear 130b is integrally formed at the lower end of the cylindrical member 130, and the gear 132, the face gear 133, the worm 134, the worm wheel 135a, the gear 135b, the gear 136, and
137 are sequentially solved and the torque from the motor 122 is
0b and the cylindrical member 130. The gear 136 and
137 are not integral with each other but are concentrically pivotally supported by a shaft 139, and as shown in FIG. 17, the arcuate groove 136a formed on the lower main surface of the upper gear 136 is lower than the lower groove 136a. A pin 137a protruding from the upper main surface of the gear 137 is slidably fitted therein. Further, as shown in FIG. 9, the support shaft 95 for rotatably supporting the movable supporting member 98 is moved to the above-mentioned non-insertion position with respect to the movable supporting member, that is, the position shown by the chain double-dashed line in FIG. A spring member 140 as a biasing force applying means for applying a biasing force toward it is fitted.

The above-mentioned motors 121 and 122 and gears 123a, 124 and 125a
, Worm wheel 125b, worm 126, and gear 127

The gears 135b, 136 and 137 and the pin 137a constitute torque applying means for selectively applying torque to each of the internal thread 123 and the cylindrical member 130. Further, the torque applying means, the female screw 123, and the cylindrical member 130.
And the male screw 96 described above, the movable supporting member 98 is swung about the supporting shaft 95 and the supporting shaft is rotated.
A carrying member driving means for moving along 95 is configured. Further, the carrying member driving means and the movable carrying member 98
The support shaft 95, the above-mentioned separating / positioning means, and the spring member 140 for imparting a biasing force to the movable carrying member 98 should move the above-mentioned playing means such as the turntable 100 to play it. A performance means transport mechanism to be mounted on the disc is configured.

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

Further, as described above, the movable carrying member 98 is swingably attached to the support shaft 95 so as to swing between the insertion position where the movable carrier member 98 is inserted between the trays of the magazine 5 and the non-insertion position, and is separated from other trays. Since the movable carrying member 98 is movable in the axial direction of the support shaft 95 so as to bring the playing means to a position corresponding to the played tray, downsizing of the player as a whole is achieved. What if
As another structure for making the movable carrying member 98 movable in two different directions in this way, for example, the movable carrying member 98 is attached to the support shaft 95 so as to swing only, and in the tray separating direction. It is conceivable to provide a movable movable member and mount the support shaft 95 on the movable member. However, in such a virtual configuration, compared to the configuration of the implementation side, the moving member,
A guide mechanism for movably guiding this in the tray separating direction is required, which leads to an increase in the number of parts and an increase in size of the player as a whole.

By the way, as is apparent from FIG. 9, the position of the support shaft 95, which is the swing center of the movable carrying member 98, is
The tray holding arms 73 to 78 which are disk holding means
The holding position of each tray by, that is, the front of the held portions 11c and 12c of each tray, and the magazine 5 formed in the player housing 2 as compared with these held portions.
It is set at a position close to the insertion port 3a for charging. By providing the swing center of the movable carrying member 98 at such a position, a relatively large space is formed in the central portion and the inner part of the player housing 2, and the above-mentioned carrying member driving means for operating the movable carrying member 98 and This space can be used as a space occupied by another mechanism, and the degree of freedom in selecting the setting position of the mechanism inside the player is increased.

Here, the motor 12 for swinging the movable carrying member 98
A structure for operating the above-mentioned disc clamp mechanism by the power generated by 2 will be described.

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

FIG. 18 shows the configuration of a control unit that controls the operation of each internal mechanism of the multiple disc storage player having the above configuration.
Cooperates with the RAM 153 in accordance with each signal from the keyboard 152 including the photosensors 84 and 112, the detection switch 111, and a switch group (not shown) in accordance with a control program stored in advance in the ROM 151, Motor 32, 108, 121
And 122, turntable 100 and pickup 155.
Issue a command to.

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

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

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

A movable locking member 19 that fixes the upper half 6 and the lower half 7 of the magazine 5 to each other by inserting and mounting the magazine 5 into the player housing 2 by the operator.
The guide shaft 25 shown in FIG. 9 pushes one of the overhanging portions 19g with the reaction force of the mounting force. As a result, the movable locking member 19 is rotated counterclockwise in FIGS. 2 and 9, and the three overhanging members 19a to 19c of the movable locking member 19 are locked by the three columnar members. When the upper half body 6 and the lower half body 7 are separated from each other by separating from 14, 16 and 17, the two can be separated from each other. In this state, the movable carrying member 98 on which the playing means including the turntable 100 is mounted is in the non-insertion position shown by the chain double-dashed line in FIG.

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

As shown in FIG. 20, when the above command is issued, the control section first causes the motor 32 to rotate normally (step S4) to rotate the two cam members 29 and 30 forward by an angle θ, for example, 30 °. The tray holding arms 43 to 48 and 73 to 78 are swung from the state shown in FIGS. 11 and 12 to the state shown in FIG. As a result, the lower half 7 of the magazine 5 is moved downward and separated from the upper half 6. Also, the 22nd
As shown in the figure, simultaneously with the separation of the lower half 7 and the upper half 6,
Of the five trays accommodated in the magazine 5, the bottom tray A11 is separated from the other trays and brought to a position corresponding to the playing means including the turntable 100.

Of the five trays arranged, when the disc containing the designated music piece is carried on the third tray A11 from the bottom, the motor 32 is further rotated in the normal direction (step
S5), both cam members 29 and 30 are further forwardly rotated by 60 ° synchronously, and the state shown in FIG. 22 is changed to the state shown in FIG. 23 through the state shown in FIG. 23, and the tray A11 carrying the desired disc is Separated from other trays. Further, in accordance with this tray separating operation, the motor 121 is rotated in the normal direction (step S5), and the movable carrying member 98 carrying the playing means is moved to the tray 2 from the lowermost position.
It is moved upward by a distance equivalent to the thickness of one sheet,
It is positioned at a position corresponding to the tray 11 separated from the other trays. The rotation angles of the cam members 29 and 30 and the rising distance of the movable carrier member 98 are detected by the two photo sensors 84 and 112 described above.
The number of the slits 83a and 113a of 3 and 113 is counted by the counter provided in the control unit, and detected based on this count value. The above operation is performed while comparing the address of the tray currently located corresponding to the playing means, that is, the address of the current disk with the address of the search disk which is the disk being searched.

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

As described above, the output of the motor 122 for swinging the movable carrying member 98 is the gear 132, the face gear 133, and the worm 1.
34, worm wheel 135a, gears 135b and 136, pin 137
a, gears 137 and 130b, a cylindrical member 130, and a pin 130a are sequentially applied to the movable supporting member 98. Before the motor 122 starts normal rotation, the arcuate groove 136a formed on the lower main surface of the gear 136 and the pin 137a planted on the upper main surface of the gear 137 so as to be slidably fitted in the groove , Which are in the positional relationship shown in FIG. When the motor 122 starts forward rotation in this state, the movable carrying member 98 is moved toward the above insertion position (the swinging position shown by the solid line in FIG. 9) by the spring member 140 attached to the support shaft 95 pivotally supporting the movable carrying member 98. Since it is biased, it is swung by the biasing force of this spring member 140. Therefore, the two gears 136 and 137 described above rotate synchronously while maintaining the relative positional relationship between the arcuate groove 136a and the pin 137a provided therein in the state shown in FIG. That is, the swinging of the movable carrying member 98 by the biasing force of the spring member 140 is in a state where the rotation of the motor 122 allows the swinging. Thus, when the movable carrying member 98 swings to the insertion position shown by the solid line in FIG. 9, the edge of the movable carrying member 98 contacts the cylindrical stopper 158, as shown in FIG.
The movable carrying member 98 is positioned at the insertion position. If the two gears 136 and 137 described above are formed integrally with each other, when this state is reached, the power transmission system including both gears is prevented from further operation. However, as described above, both gears 136 and 137 are relatively rotatable within the range in which the pin 137a slides in the arcuate groove 136a.

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

After the above operation, a certain period of time is waited (shown in step S9 in FIG. 20), whereby the control unit determines that the swing of the movable supporting member 98 and the operation of the disc clamp mechanism are completed, and the motor 122 Is stopped (step S10).
After that, the servo driving means (not shown) of the objective lens 105 included in the pickup is operated, and the motor 108 is rotated in the normal direction (step S11) to start the movement of the carriage 103 including the pickup to perform the performance. Start.

When it is confirmed that the performance of the first disc is completed (step S12), the control unit stops the forward rotation of the carriage driving motor 108 and the operation of the pickup,
Immediately, the motor 108 is reversed (step S13). By the reverse rotation of the motor 108, the carriage 103 having the pickup mounted thereon is brought closest to the turntable 100 mounted on the swinging end of the movable carrying member 98. Carriage 1
When 03 is closest to the turntable 100, the carriage 103
The protrusion formed on the ridge engages with the actuator 111a of the detection switch 111 shown in FIG. 9 to activate the detection switch. The control unit recognizes that the carriage 103 is closest to the turntable 100 based on the detection signal issued from the detection switch 111 (step S14), and accordingly stops the motor 108 to stop the carriage 103. (Step S15).

After the above operation, the motor 122 is rotated in the reverse direction (step S16) to release the disc clamp and
The movable carrying member 98 is swung from the insertion position shown by the solid line in FIG. 9 to the non-insertion position shown by the chain double-dashed line. In addition,
The releasing operation of the disc clamp and the returning operation of the movable supporting member 98 are performed in the reverse process of the above-described disc clamping operation and the swinging operation of the movable supporting member 98 to the insertion position, and therefore will not be described in detail.

As shown in FIG. 9, when the movable carrying member 98 returns to the non-insertion position, the photosensor 112 provided on the swing groove portion of each movable carrying member detects the address plate 1.
It reaches the position where 13 can be detected and detects it. For example, the control unit recognizes that the return operation of the movable supporting member 98 is completed based on the detection signal emitted from the photo sensor 112 (step S17), and stops the motor 122 to stop the movable supporting member 98 ( Step S18).

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

With such a configuration, downsizing of the player is achieved. What is important is that the player housing 2 is usually formed in a rectangular parallelepiped shape as shown in the embodiment, and since the disc accommodated therein is circular, relatively large spaces are formed at the four corners inside the player housing 2. Therefore, when the longitudinal movable carrying member 98 is in the non-opposing position, the movable carrying member is arranged so as to be close to and along the inner wall surface of the player housing 2, and the end of the movable carrying member 98 is arranged. The part is inevitably accommodated in any of the four corner spaces. Therefore,
After the performance is finished, the carriage 103 is moved to the movable supporting member 9 as described above.
If the movable carrying member is returned to the non-opposing position after being moved to the end portion of 8, the movable carrying member is brought close to the inner wall surface of the player housing 2 when the space of this corner is in the non-playing time. If the movable carrying member 98 is configured to be positioned so as to follow it, the end portions of the movable carrying member 98 are necessarily accommodated in any of the four corner spaces. Therefore, if the carriage 103 is moved to the end portion of the movable supporting member 98 after the performance as described above and then the movable supporting member is returned to the non-opposing position, the space at this corner is the carriage 103 during non-performance. Is effectively used as a housing space for the player, the space utilization efficiency inside the player housing 2 is improved, and the player can be easily downsized.

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

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

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

On the other hand, if the second disc to be played is carried on, for example, the second tray from the top (fourth from the bottom) of the five trays, the controller is Reverses the motor 32 (step S24) to move the two cam members 2
By reversing 9 and 30, the state shown in FIG. 24 is changed to the state shown in FIG. 23, and the second tray B12 from the top is separated from the other trays. Also, with this tray separation operation,
The motor 121 is rotated in the reverse direction (step S24), and the movable carrying member
98 is lowered from the position determined in the first loading subroutine by a distance corresponding to the thickness of one tray, and the playing means is positioned at a position corresponding to the second tray B12 from the top.

By the above operation, if the address of the current disc matches the address of the second disc to be played which is the search disc (step S25), the motor 32 and the motor 1
21 is stopped (step S26), and thereafter, steps S8 to S18 in the above-mentioned first loading subroutine are performed.
Based on steps S27 to S37 similar to the above, each mechanism is operated and the second disc is played.

After that, as shown in FIG. 19, the presence or absence of the third and subsequent unplayed discs is checked (step S40), and if three or more discs are designated, they are played according to the second loading subroutine described above. If all the performances of the specified disc have been completed, all the mechanisms are put into the performance standby state or the operation is stopped.

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

EFFECTS OF THE INVENTION As described in detail above, in the multiple disc storage player according to the present invention, the magazine is housed in a housing composed of a pair of upper and lower halves which are separable from each other, and arranged in the housing. A plurality of plate-shaped trays each of which can carry a disc on its main surface and which can be housed in the housing so as to project along the respective main surfaces. The upper half body and the lower half body are formed in response to a performance command. Separation and positioning means for separating and positioning a tray carrying a desired disk among the respective trays, holding it, separating it from other trays in the direction perpendicular to the main surface of the tray, and positioning the tray. Of the turntable so as to be movable between an insertion position and a non-insertion position that can be inserted between the trays in a direction substantially perpendicular to the separation direction of the turntable. A tray carrying a disc to be played is provided with a movable carrying member carrying a playing means including a bull, a pickup and a disc clamp mechanism, and a carrying member driving means for appropriately moving the movable carrying member in the respective directions. After being separated from other trays by the separation positioning means,
The movable carrying member is inserted between the trays, the playing means is attached to the disc, and the disc clamping mechanism clamps the disc so that the pickup operates to start the performance.

Due to this structure, the space to be provided in the player housing for mounting the playing means on the disc to be played is extremely small, and the player as a whole can be downsized. For example, for a vehicle, a dashboard of an automobile. It can also be used by being stored in the space formed in.

Further, in the multiple disc storage player according to the present invention, the separation positioning means is provided so as to be swingable in a plane including the separation direction, and a plurality of tray holding arms for holding each of the toluys at their free ends. , A holding arm drive means for swinging the tray holding arm, and a portion of each of the tray holding arms near a free end of a tray holding arm for holding a tray separated from another tray is substantially the same as the held tray. It will be parallel. Due to such a structure, the playing means and the movable carrying member mounting the playing means can always be smoothly inserted between the trays without interfering with the tray holding arm, and the playing means can be securely and smoothly mounted on the disc. . Further, with this configuration, the gap between the separated trays can be reduced, and the player as a whole can be further downsized.
