Abstract

PURPOSE:To avoid a disk retrieval impossible state to smoothly play plural disks continuously by positioning a disk storage part and an operating means relatively in the disk orientation direction and moving disks between them in a player storing plural disks. CONSTITUTION:A disk moving member 18 is temporarily slightly moved in the direction opposite to the direction, where it should be moved, to release a tray 11 from the binding state to a magazine main body 8, and thereafter, the member 18 is returned to the home position once by the detection signal from a detecting switch. When a photo sensor confirms this return to the home position, the member 18 is moved to a designated position corresponding to a designated disk; and when the photo sensor cannot detect the detection signal over a prescribed time, the operation is repeated until it is obtained. The member 18 is moved by combination of a moving plate, a rack part, a double gear, etc., and desired movement results are obtained. Thus, the increase of the frictional force between the magazine main body 8 of a magazine 5 and trays 11 and 12 is eliminated by repeating the operation.

Description

TECHNICAL FIELD The present invention relates to a disc player, and more particularly to a multi-disc storage player that can store a plurality of discs and can sequentially select any one of the stored discs for continuous play. .

BACKGROUND ART A multi-disc storage player is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-261.
It is known from Japanese Patent Application No. 853, and includes a performance means including a turntable, a pickup, etc., a magazine as a disk storage part that can arrange and store a plurality of discs and is inserted into a mounting part in a player housing, and The apparatus includes a disk ejecting and transporting mechanism that sequentially selects arbitrary disks and transports them onto the disk holding surface of the turntable, and conversely returns them from the disk holding surface into the magazine.

In such a multi-disk storage player, when a selected disk is transferred from the magazine onto the turntable, the disk is moved in two directions: one parallel to the disk supporting surface of the turntable and one perpendicular to the direction. This is done by the disk ejecting and transporting mechanism described above. Specifically, the disks are arranged in the magazine in a direction perpendicular to the disk supporting surface of the turntable, and either the playing means including the turntable or the like and the magazine are supported on a predetermined movable member. The movable member is reciprocated in the disk arrangement direction, thereby replacing movement of the disk in a direction perpendicular to the disk supporting surface of the turntable.

Further, movement of the disk in a direction parallel to the disk supporting surface of the turntable is completed by simply protruding the disk from the magazine.

A structure for reciprocating the above-mentioned playing means together with the above-mentioned movable member on which it is mounted in the disk arrangement direction will be explained by taking as an example the structure of a multi-disc storage player shown in Japanese Patent Application Laid-Open No. 61-261853.

The member indicated by reference numeral 151 in FIGS. 39 to 41 is a supporting member constituting the above-mentioned movable member, and performance means including a turntable 152, a pickup 153, etc. are mounted on the supporting member. . In addition, FIGS. 40 and 41 are respectively IVX-r with respect to FIG. 39.
They are a VX arrow view and a TVXl-rVX I arrow view.

This supporting member 151 is mounted on the chassis 154 so as to be able to reciprocate in the vertical direction (in the direction of arrow Z and in the opposite direction). As shown in FIGS. 42 and 43, the disks 156 in the magazine 155 are also arranged in the vertical direction, and the direction in which the disks 156 are arranged in the magazine 155 coincides with the direction in which the supporting member 151 moves.

A pair of movable members 158 and 159 extending in the front-rear direction (arrow Y direction and the opposite direction) are provided on both left and right sides of the chassis 154 (each side in the direction of arrow X and the opposite direction), and are movable in the front-rear direction. It is provided. Although not shown, a drive mechanism including a motor for moving each moving member 158, 159 is provided. A total of three pins 151a are provided on the supporting member 151, one on the left side and two on the right side. Each of these pins 151
a is a cam portion 15 formed on each moving member 158, 159;
8a and 159a. Moving member 15
8 and 159 reciprocate (in the direction of arrow Y and the opposite direction), the supporting member 151 is intermittently moved up and down (
Each cam portion 15
8a.

159a is formed to be inclined in a stepwise manner with respect to the moving direction of moving members 158 and 159.

In this configuration, the supporting member 151 moves up and down as the moving members 158 and 159 are reciprocated by being given a driving force, thereby moving the playing means such as the turntable 152 and the magazine 155 in the disk arrangement direction (arrow relative movement in the Z direction and its opposite direction).

Next, a configuration for conveying a disk in a direction parallel to the disk supporting surface of the turntable 152 will be described.

As shown in FIGS. 42 and 43, a magazine 155 serving as a disk storage section is comprised of a generally rectangular parallelepiped-shaped housing 161 and a turntable 152 disposed within the housing.
The disks 156 are arranged in a direction substantially perpendicular to the disk supporting surface (direction of arrow Z and the opposite direction) and are rotatably provided around support shafts 152 that extend in the direction of arrangement, with disks 156 on each main surface. It is comprised of a plurality of plate-shaped trays 164 that can be carried and protruded from the housing along each main surface. That is, by simply protruding the plate-like trays 164 each carrying a disk 156 from the housing 161, the disks 15
6 is conveyed in one direction (the disk is conveyed in a direction parallel to the disk supporting surface of the turntable).

As shown in FIG. 43, on the right side of the magazine 155 there is a /X housing 161 that engages with each tray 164 to
A carrying member 15 on which a tray engaging member 166 for pushing out is arranged and on which the above-mentioned playing means is mounted.
1 so as to be rotatable. In addition, the supporting member 15
1, a sliding member 167 is provided at the rear of the magazine 155 so as to be able to reciprocate linearly in the left-right direction (the direction of the arrow X and the opposite direction), and the sliding member The end 1 in the forward direction is moved by
At 67a, it engages with the free end of the tray engaging member 166 to apply a rotational moment to the tray engaging member, causing it to rotate.

That is, the tray engaging member 166 is rotationally driven to push the tray 164 to protrude outside the housing 161, and the disc 156 on this tray is moved onto the turntable 1.
52.

As shown in FIGS. 43 and 44, two bottles 166a are provided protruding from the tray engaging member 166, and the two arcuate guide grooves formed in the above-mentioned supporting member 15. When the pins 166 are slidably engaged with the pins 151a and 151b, the disk engaging member 166 is guided and rotated.

Further, as is clear from FIG. 43, the rotation center axis of each tray 164 (the center axis of the support shaft 162) and the rotation center axis (imaginary) of the tray engaging member 166 are made to coincide.

Incidentally, the above-described multi-disc storage player is provided with a detection means for detecting that the protrusion and storage of each tray 164 with respect to the housing 161 of the magazine 155 has been completed. Specifically, the detection means includes a sliding member 167 (
42 and 43) or a driving force transmission member (not shown) for transmitting driving force from a motor or the like to the sliding member. The sliding portion consists of a detection switch (not shown) that is turned on and off by reciprocating the driving force transmitting member.

In the multi-disc storing player having such a configuration, when returning the disc 156 from the turntable 152 into the magazine 155, the tray engaging member 166 is
By rotating the magazine 155 clockwise in the figure, the tray 164 protruding from the housing 161 of the magazine 155 is housed in the housing together with the disc. At the same time as this operation, the detection switch (not shown) is turned ON or OFF.
The completion of returning the disk 156 into the magazine 155 is confirmed. Then, in response to a detection signal from this detection switch, a supporting member 151 carrying playing means including a turntable 152 is moved in the disk arrangement direction, and is moved to a designated position corresponding to the next disk to be played. Positioned. Thereafter, the tray engaging member 166 is rotated counterclockwise in FIG.
61, and the disc is protruded from the turntable 15.
It is attached to 2. Then, the performance of this second disc is started.

In the multi-disk storage player with the above configuration,
The frictional force between the housing 161 and each tray may increase due to the influence of fingers or moisture attached to each tray 164, and the rotational movement of each tray 164 may not be performed smoothly. In this case, as shown in FIG. 45, there is a concern that the detection switch may be activated and a detection signal may be generated even though the tray 164 is not completely housed in the housing 161. After all, the tray engaging member 1
66, each member such as the sliding member 167 and the driving force transmitting member (described above) that transmits the driving force to the sliding member may be slightly deformed by the driving force, or the entire mechanism consisting of each member may be The tray 164 is compressed within the cumulative tolerance range provided between the two, and the frictional force causes the tray engaging member 166 to stop rotating before the tray 164 reaches the position where the tray 164 is completely pushed into the housing 161. This is because the member for activating the detection switch may move the actuator of the detection switch even though it is blocked.

As shown in FIG. 45, in this case, even if an attempt is made to raise the support member 151 to bring it to the specified position corresponding to the next disc to be played, the support member 151 will not be able to reach the tray 164 that still protrudes outside the housing 161. (or components mounted on the supporting member) come into contact with each other, and the operation is blocked, resulting in a state in which the disc cannot be searched.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and an object thereof is to avoid the occurrence of a state in which a disc cannot be searched due to incomplete storage of a disc in a disc storage unit, and to prevent a disc search from occurring due to a disc being incompletely stored in a disc storage unit. To provide a multi-disc storage player capable of smoothly performing continuous performances.

The multi-disc storage player according to the present invention includes a positioning means for relatively positioning a disc storage section capable of arranging and storing a plurality of discs and a playing means in the disk arrangement direction, and a positioning means for relatively positioning a disc storage section capable of arranging and storing a plurality of discs and a playing means; The positioning means includes a movable member that carries either the disc storage section or the playing means, a drive machine that moves the movable member in response to a movement command, and a player that moves the movable member in response to a movement command. control means for issuing a movement command to the drive mechanism until the specified position corresponding to the disk specified by the command matches the current position of the movable member, and the control means is configured to move the drive mechanism in one direction. When it is detected that a predetermined period of time has elapsed until the current position of the movable member matches the designated position after issuing a movement command to The present invention is characterized in that a movement command is issued to release the engagement state between the movable member and its mounting components and the disk that is not completely accommodated in the disk storage section.

Further, the driving means and the supports 78 and 79 constitute a pressing member moving means for attaching and detaching the suppressing member 80 to and from the turntable 23. Further, the pressing member moving means and the suppressing member 80 constitute a clamping mechanism that clamps the disk IO. As shown in FIGS. 22 and 23, a spring member (
(not shown) is provided.

FIG. 10 shows the view taken along the line X-X in FIG. A tapered portion 78g is formed which engages and positions the pressing member relative to the turntable 23, in this case positioning within a plane parallel to the disk supporting surface 23a of the turntable 23. Thereby, the pressing member 80 is centered with respect to the turntable 23 with high precision.

Here, the shapes of the turntable 23 and the suppressing member 80 will be described in detail.

As is clear from FIG. 10, the suppressing member 80 is provided with a disk alignment protrusion 80a that fits into the center hole of the disk 10 to align the disk. On the other hand, the turntable 23 is provided with a recess 23c into which the disk alignment protrusion fits when the disk is clamped. This configuration prevents the disc 10 from shifting in a direction parallel to the disc supporting surface 23a of the turntable 23.

The above-mentioned clamp mechanism holds the disc 10 supported on the tray 11 or 12 which is projected outside the magazine body 8 by the tray projecting means described above onto the turntable 2.
3 in a direction perpendicular to the disk holding surface 23a (see FIG. 10), in this case upward (in the direction of arrow Z).

As shown in FIG. 9, a disk holding member driving cam 87 formed in a substantially arcuate shape is provided on the moving member 18, and the disk holding member driving cam 87 is provided on the moving member 18, and is rotated about the center of its entire curvature via a pin 87a. It is attached to a moving member 18 for movement. FIG. 30 shows details of this disk pressing member drive cam 87. As shown in FIGS. 9 and 30, an opening 87c is formed at one end of the disk pressing member drive cam 87, and a pin 82h is provided at the end of the clamper cam 82 to protrude upward. (See FIGS. 9 and 26 (ω and peaks)) fits smoothly into the opening. That is, as the clamper cam 82 moves, the disk pressing member drive cam 87 moves. This disk holding member drive cam 87 is used to hold a disk that is moved from above the tray 11 or 12 in a direction perpendicular to the disk holding surface 23a (see FIG. 10) of the turntable 23 by the aforementioned clamp mechanism. A device for driving a disk holding member 88 (shown in FIG. 31 (fields and mountains)) that comes into contact with the surface facing the disk supporting surface and thereby maintains the parallelism of the disk 10 with respect to the disk supporting surface. It is. That is, when the disk holding member drive cam 87 moves along its curvature, the disk holding member 88 moves up and down while in contact with the disk.

Turning around, as shown in FIGS. 6 and 11, the chassis 1
In addition to the detection switches 34 and 35, two other detection switches 8 and 90 are attached to the sensor 6. Both detection switches 89 and 90 are for engaging with the moving body 56 driven by the motor 62 and detecting the moving position of the moving body.

The above-mentioned control section controls each tray 11, 1 of the magazine 5 by a detection signal emitted from one of the eight detection switches.
2 is stored in the magazine body 8. Further, by the detection signal issued from the other detection switch 90, it is detected that each tray 11, 12 has protruded outside the magazine body 8 and that the disk on the tray has been clamped to the turntable 23.

32 (J and ridges) show details of the tray engaging member 53 described above. Further, FIG. 33(a) and the rack portion 56a (see FIG. 17(a)) of the above-mentioned moving body 56 (see FIGS. 6, 16, and 17).

This figure shows the details of the gear 57 that meshes with the first song (see song 1). However, this gear 57 is formed by integrally molding a large gear part (no reference numeral) and a small gear part 57a, and meshes with the rack part 56a at the small gear part 57a.

As shown in FIG. 33 (■ and crests), a small gear portion 57a of the gear 57 has a notch 57b formed in one of its teeth. On the other hand, as shown in FIGS. 11 and 11, the rack portion 56a of the movable body 56 with which the small gear portion r37a meshes has two protrusions 56g corresponding to the notch portions 57b. It is formed.

That is, when the small gear portion 57a of the gear 57 and the rack portion 56a are engaged with each other during assembly of the disc player, if the notch portion 57b and the protrusion 56g are not aligned, the differential movement of the gear 57 and the movable body 56 will be interrupted. It is structured in such a way that it does not occur.

FIG. 35 shows the configuration of a control unit that controls the operation of the multi-disc storage player configured as described above, and the CPU 100 is
In accordance with a control program stored in advance in the OM101, in response to signals from the keyboard 102 consisting of the detection switches 34, 35, 49, 89, 90, the photosensor 51, and the switch group of the operation unit 6 (shown in FIG. 1). RAM
Motors 45, 62 . A command is issued to the spindle motor 25 and carriage motor 104.

An example of the control program will be described with reference to the flowchart shown in FIG. 36 and the operation diagrams shown in FIGS. 37(a), (b) and 38.

The control program shown by the flowchart in FIG. 36 is started when a disc return command is issued to the motor 62 in response to a disc play command.

That is, when a disk return command is issued, the motor 62 starts to rotate in reverse, and a disk clamp release operation and a disk return operation, which are opposite to the disk clamp operation and disk load-in operation described later, are performed, and the disk on the turntable is moved into the magazine 5. will be returned to. and,
After confirming the return of this disc (step S1), the next target disc number is taken in (step S2), and a selector movement command is issued to bring the moving member 18 carrying the playing means to the specified position corresponding to the target disc. (Step S3). Note that the term "selector" used herein is another name for the moving member 18 that carries the playing means.

After issuing the selector movement command, the control unit checks whether the current disk Nα has become equal to the target disk Nα (step S4). If the current disk Nα and the target disk Nα are equal, and if it is stored that a disk search operation has already been performed once and the search ended in failure, this memory content is immediately erased (step S5). At the same time, the selector movement command is canceled (step S6).

Next, the motor 62 is rotated to project the designated disk out of the magazine 5, and the movable body 56 (shown in FIG. 16, etc.) is driven backward (in the opposite direction of the arrow Y direction).

At this time, the movable body 56 is in a locked state with the second lever member 72 by locking/releasing means comprising movable pieces 75, 76 (see FIG. 16, etc.).

Note that the first lever member 71 is not yet locked with the movable body 56. Therefore, only the second lever member 72 is connected to the movable body 5.
6, and thereby the tray engaging member 5
3 rotates counterclockwise in FIG. Therefore, as shown in FIGS. 2(b) and 37(a), a tray (for example, tray B1) carrying a disc 10 to be played is shown.
2) protrudes from the magazine body 8, and the disc is located concentrically with respect to the disc supporting surface 23a of the turntable 23;
In other words, it moves to just below the disk holding surface.

After that, the movable body 56 moves further backward (in the opposite direction of the arrow Y direction), but the second lever member 72 is released from the locked state with the movable body, and at the same time, the first lever member 71 locked against.

Therefore, the first lever member 71 moves rearward together with the transfer body 56, and thereby the supports 78, 79 of the clamping mechanism
(shown in FIG. 23 etc.) swings upward (in the direction of arrow Z). Therefore, as shown in FIG. 37(b), the disc 10 is lifted upward from the tray 12 by the clamp mechanism and is clamped against the turntable 23.
The disk load-in operation is completed (step S7).

It should be noted that confirmation that the disc is clamped on the turntable 23 is made by a detection signal generated when the detection switch 90 shown in FIGS. 6 and 11 is activated by the movable body 56.

In this way, it is possible to perform, and the control section is a spindle servo,
Servo systems such as focus servo and tracking servo are activated (step S8), TOC information is read (step S9), the search for the target song is eliminated (step 510), and the performance is started (step 5ll).

On the other hand, after issuing the selector movement command (step S3),
If the current disk Nα does not become equal to the target disk Nα even after a certain period of time has elapsed (step 512), that is, if the disk search operation becomes impossible, this is the second time, including this time, that such a disk search impossible state has appeared. Check whether there is one (step 813).

Here, we will explain the possible causes of the disk search becoming impossible.

As shown in FIG. 38, the disc 10 that finished playing first
When the tray 11 carrying the . It is conceivable that the frictional force between the tray and the tray has increased, making it impossible to completely push the tray into the magazine body 8. In this case, even though the tray 11 is not completely housed in the magazine body 8, a detection signal may be emitted from the detection switch 89 for detecting that the tray is housed in the magazine body 8. In other words, each member such as the tray engaging member 53 and the plurality of drive force transmitting members that transmit the driving force from the motor 62 to the tray engaging member may be slightly deformed by the driving force, or the entire mechanism consisting of the respective members may be deformed little by little due to the driving force. is compressed within the range of the cumulative tolerance provided between each member, and the tray engaging member 53 completely holds the tray 11 due to the frictional force between the magazine body 8 and the tray 11. Even though the rotation is blocked before reaching the position where it is pushed into the magazine body 8, the movable body 56 for activating the detection switch 89 can move the actuator of the detection switch 89.

As shown in FIG. 38, in this case, even if the moving member 18 is raised to bring the playing means to the designated position corresponding to the next disc 10 to be played as described above, there is still some material outside the magazine body 8. Tray 11 with a part protruding
The end of the movable member 18 or a component mounted on the movable member comes into contact with the movable member 18, and the upward movement of the movable member 18 is blocked, making it impossible to search for the disc.

If it is the second time that the disk search impossible state as described above has appeared, the memory contents of the first disk search impossible state are erased (step 514), and the selector movement command is canceled (step 515). Then, the light emitting diode (LED) indicating that the disc is being played is turned off (steer knob 816) and the operation is stopped.

On the other hand, if the disk search impossible state has appeared for the first time in step 31B, first, it is stored that the disk search impossible state has reached one lipstick (step 517). Then, the current disk Nα and the target disk Nα are compared (step 518), and the target disk Nα is the current disk Nα.
If it is higher than α, that is, if the movable member 18 is currently being raised (in the direction of arrow Z), a selector movement command is issued for a certain period of time to temporarily lower the movable member 18 to the value (step S19.S20
．． 521). Conversely, if the target disk number is currently lower than the disk Nα and the movable member 18 is about to be lowered, the selector is pressed to temporarily raise the movable member 18 to the value (UP). A movement command is issued (steps 522S20, 521). in this way,
By once driving the moving member 18 in the opposite direction to which the driving force was applied to raise or lower it, the tray 11 is now in a state where it is competing with the magazine body 8 due to frictional force.
The movable member 18 gives the impression that a striking force has been applied once to the moving member 18. Therefore, the tray 11 is the magazine main body 8.
freed from the state of antagonism.

After this, wait for the elapse of a predetermined time (step 823), and preferably the disk engaging member 53 (FIGS. 9 and 32).
The tray 11, which was partially protruding outside the magazine body 8, is completely housed in the magazine body 8 as shown in FIG. In addition, in this way, the tray 11 is connected to the disk engaging member 53.
The tray 11, which is released from the antagonistic state due to the frictional force with the magazine body 8, is pushed into the magazine body 8 by the biasing force of the pressing lever 14 inside the magazine body 8 as shown in FIG. Can be completely drawn in.

As described above, after the tray 11 is released from the antagonistic state with the magazine body 8 by once moving the movable member 18 in the opposite direction to the direction in which it should be moved, the movable member 18
is returned to the lowest position as the home position until a detection signal is issued by the detection switch 49 (step 524).

After obtaining a detection signal from the photosensor 51 (step 525) and confirming that the moving member 18 has returned to the home position, the presence or absence of the 5TOP command is checked (step 52).
6) After that, move the moving member 18 to the specified position corresponding to the specified disk.

The positioning operation of the movable member 18 to the specified position after returning to the home position and the subsequent performance start operation are performed along the aforementioned operation path (steps 84 to 511).

Further, after issuing a selector movement command to return the moving member 18 to the home position, if a detection signal from the photosensor 51 indicating that the home position has been reached is not obtained even after a predetermined period of time has passed (step 527). , the operation from step 913 described above is repeated, assuming that the disk cannot be searched. Thereafter, the above operations are repeated according to the specified number of songs.

In this embodiment, the cam grooves 37d and 38d are formed by forming a rack portion 37h on the movable plate 37 and rotating the double gear 40 that meshes with this rack portion.
The moving member 18 is moved through the moving plate 3, thereby relative positioning of the magazine 5, which is a disk storage section, and the playing means in the disk arrangement direction.
It is also possible to form a rack directly on the movable member 18 without using 7.38, and to rotationally drive a gear that meshes with this rack.

Further, in this embodiment, a case is shown in which the frictional force generated between the magazine body 8 of the magazine 5 and each tray 11, 12 increases and the tray is not completely accommodated in the magazine body 8. In a player equipped with a disc storage section that does not have such trays 11 and 12 and has a plurality of disc storage shelves that directly accommodate discs, the following also applies when the frictional force generated between the disc storage section and the discs increases. The same is true.

Effects of the Invention As detailed above, the multi-disc storage player according to the present invention includes a positioning means for relatively positioning a playing means and a disk storage section capable of arranging and storing a plurality of discs in the disk arrangement direction; The positioning means includes a disc moving means for moving the disc between the storage section and the playing means, and the positioning means includes a movable member carrying either the disc storage section or the playing means, and a movable member that moves the movable member in response to a movement command. The drive mechanism includes a drive mechanism that causes the drive mechanism to move, and a control means that issues a movement command to the drive mechanism until the current position of the movable member matches the designated position corresponding to the disc specified by the performance command, and the control means controls the drive mechanism. When it is detected that a predetermined period of time has elapsed until the current position of the movable member matches the designated position after issuing a movement command in direction 1 to the mechanism, Issue a movement command in the direction opposite to the direction of.

That is, for example, the frictional force between the disc storage unit and the disc to be stored in the disc storage unit or the tray supporting the disc becomes so large that the disc that has finished playing cannot be completely stored in the disc storage unit and the disc is Alternatively, a state may occur in which a part of the tray still protrudes outside the disc storage part, and the movable part or its mounted parts engages with the disc or tray, causing the relative performance of the playing means with respect to the disc storage part. If the movement is blocked, the movable member is first moved in the opposite direction to the direction in which it should be moved to release the engaged state. Through this series of engagement and disengagement operations, a state similar to that of a single impact force being applied to the disk or tray that is in opposition to the disk storage section due to frictional force occurs, and the disk or tray is in a state of conflict with the disk storage section. Thereafter, the disk is smoothly stored in the disk storage section by the action of the disk moving means described above and the biasing means provided in the disk storage section for drawing the disk.

Therefore, the occurrence of a state in which a disc cannot be searched due to an incomplete storage of a disc in the disc storage unit is avoided, and continuous performance of a plurality of discs can be performed smoothly.
