Description

Description: TECHNICAL FIELD The present invention relates to a disc player, and more particularly, to a multi-disc storage player capable of storing a plurality of discs and capable of sequentially selecting any one of the stored discs and playing continuously. .

BACKGROUND ART A multi-disk storage player is disclosed in, for example,
And a playing means including a turntable, a pickup and the like, a magazine capable of arranging and storing a plurality of discs and being inserted into a mounting section in a player housing, and an optional disc in the magazine. And a disk take-out / transport mechanism for sequentially selecting the disks and transporting the disks onto the disk carrying surface of the turntable, and conversely returning the disk from the disk carrying surface to the magazine.

In such a multi-disk storage player, when a selected disk is transported from the magazine to the turntable, the disk is moved in two directions: a direction parallel to the disk holding surface of the turntable and a direction perpendicular to the direction. This is performed by the above-described disc take-out and transport mechanism. Specifically, the disks are arranged in a direction perpendicular to the disk holding surface of the turntable in the magazine, and one of the playing means including the turntable and the magazine is held on a predetermined movable member. The movable member is reciprocated in the disk arrangement direction, thereby replacing the movement of the disk in a direction perpendicular to the disk holding surface of the turntable. The movement of the disk in a direction parallel to the disk holding surface of the turntable is completed by simply protruding the disk from the magazine.

A configuration for reciprocating the above-mentioned playing means in the disk arrangement direction together with the above-mentioned movable member mounted thereon will be described with reference to an example of the configuration of a multiple disk storage player disclosed in Japanese Patent Application Laid-Open No. 61-261852.

A member denoted by reference numeral 151 in FIGS. 39 to 41 is a carrying member constituting the above-mentioned movable member, and a playing means including a turntable 152 and a pickup 153 is mounted on the carrying member. . FIG. 40 and FIG.
41 is an IVX-IVX arrow view and IVXI-IV in FIG. 39, respectively.
FIG. The support member 151 is mounted on the chassis 154 so as to be able to reciprocate up and down (in the direction of arrow Z and in the direction opposite thereto). As shown in FIGS. 42 and 43, the arrangement of the disks 156 in the magazine 155 is also made in the vertical direction, and the arrangement direction and the moving direction of the support member 151 coincide.

A pair of moving members 158 and 159 extending in the front-back direction (arrow Y direction and the opposite direction) are provided on both left and right sides of the chassis 154 (sides in the arrow X direction and the opposite direction) so as to be movable in the front-rear direction. Is provided. Although not shown, a drive mechanism including a motor for moving each of the moving members 158, 159 is provided. The support member 151 is provided with a total of three pins 151a, one on the left side and two on the right side. Each of these pins 151a is connected to each of the moving members 158, 15
9 are fitted into cam portions 158a, 159a formed in the same. As the moving members 158, 159 reciprocate (arrow Y direction and the opposite direction), the support member 151 intermittently moves up and down (arrow Z direction and the opposite direction) to correspond to the storage position of each disk 156 of the magazine 155. As each cam part 15
8a and 159a are formed to be inclined stepwise with respect to the moving direction of the moving members 158 and 159.

In this configuration, the carrying members 151 move up and down as the moving members 158 and 159 reciprocate under the application of a driving force, whereby the playing means such as the turntable 152 and the magazine 155 are arranged in the disk arrangement direction (arrow Z direction). And the opposite direction).

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

As shown in FIGS. 42 and 43, a magazine 155 serving as a disk storage portion is
And a support shaft 152 arranged in the housing in a direction substantially perpendicular to the disk carrying surface of the turntable 152 (the direction of the arrow Z and the direction opposite thereto) and rotatable about a support shaft 152 extending in the arrangement direction. The housing is constituted by a plurality of plate-like trays 164 each of which can carry the disk 156 on its main surface and which can be stored in the housing along the main surface. That is, the disk 156 is transported in one direction (disk transport in a direction parallel to the disk bearing surface of the turntable) by simply protruding the plate-shaped tray 164 carrying the disk 156 from the housing 161. It is.

As shown in FIG. 43, on the right side of the magazine 155, a tray engaging member 166 for engaging with each tray 164 and pushing the tray out of the housing 161 is arranged, and
It is rotatably provided on a supporting member 151 on which the above-mentioned playing means is mounted. A sliding member 167 is provided on the supporting member 151 at the rear of the magazine 155 so as to be linearly reciprocable in the left-right direction (the direction of the arrow X and the opposite direction). The tray engaging member 16 is moved by the driving force applying means and at its forward end 167a.
6 to give a rotational moment to the tray engaging member to rotate it.

That is, the tray engagement member 166 is driven to rotate, thereby pushing the tray 164 to protrude out of the housing 161, and mounting the disk 156 on this tray to the turntable 152.

As shown in FIGS. 43 and 44, two pins 166a are protruded from the tray engaging member 166, and the two arc-shaped guide grooves formed in the above-described support member 15 are formed. When the pin 166 is slidably engaged with 151a and 151b, the disk engaging member 166 is guided to rotate. Also,
As is apparent from FIG. 43, the rotation center axis of each tray 164 (the center axis of the support shaft 162) and the rotation center axis (virtual) of the tray engaging member 166 are aligned.

By the way, in the above-described multi-disk storage player, each tray 16 with respect to the housing 161 of the magazine 155 is provided.
There is provided a detecting means for detecting that the protrusion and the storage of 4 are completed. Specifically, the detecting means includes a sliding member 167 (FIG. 42 and FIG.
43) and a driving force transmitting member (not shown) for transmitting a driving force from a motor or the like to the sliding member so that the actuator can be engaged with the sliding member. It comprises a detection switch (not shown) that is turned on and off by the reciprocating movement of the driving force transmitting member.

In a multi-disc storage player having such a configuration,
The disc 156 is inserted into the magazine 155 from the turntable 152.
When returning the tray, the tray engaging member 166 is rotated clockwise in FIG. 43, and the tray 164 projecting out of the housing 161 of the magazine 155 is stored in the housing together with the disk. At the same time as this operation, the detection switch (not shown) is turned ON or OFF, and the magazine 1
The completion of returning the disk 156 to the inside of the disk 55 is confirmed. Then, in response to the detection signal from the detection switch, the carrying member 151 on which the playing means including the turntable 152 is mounted is moved in the disk arrangement direction, and is positioned at a designated position corresponding to the disk to be played next. Is done. Thereafter, the tray engaging member 166 is rotated in the counterclockwise direction in FIG. 43, and the tray 164 holding the disk is projected out of the housing 161 and the disk is mounted on the turntable 152. Then, the performance of the second disc is started.

In the multiple disk storage player having the above-described configuration, when the frictional force between the housing 161 and each tray increases due to the influence of resin or moisture attached to each tray 164, the rotation operation of each tray 164 cannot be performed smoothly. There is. In this case, as shown in FIG. 45, there is a concern that the detection switch is operated and a detection signal is generated even though the tray 164 is not completely stored in the housing 161. Each member such as the tray engaging member 166, the sliding member 167, and the driving force transmitting member (described above) for transmitting the driving force to the sliding member is slightly deformed by the driving force. The entire mechanism consisting of the components is compressed and contracted within the range of the accumulated value of the tolerances provided between the members, and the position at which the tray engaging member 166 completely pushes the tray 164 into the housing 161 by the frictional force described above. This is because a member for activating the above-mentioned detection switch can move the actuator of the detection switch even though the rotation thereof has been prevented before that. As shown in FIG. 45,
In this case, even if it is attempted to raise the carrying member 151 to the designated position corresponding to the disk to be played next, the carrying member 151 (or the supporting member The mounted components) are in contact with each other and the operation is blocked, and the disk cannot be retrieved.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points,

FIG. 35 shows a configuration of a control unit that controls the operation of the multiple disk storage player having the above configuration, and the CPU 100 detects the detection switches 34, 35, 49, 89, 90 in accordance with a control program stored in the ROM 101 in advance. A command is issued to the motors 45 and 62, the spindle motor 25, and the carriage motor 104 in cooperation with the RAM 103 in response to a signal from a keyboard 102 comprising a switch group of the photo sensor 51 and the operation unit 6 (shown in FIG. 1).

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

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

That is, when a disk return command is issued, the motor 62 starts to rotate in the reverse direction, and a disk clamp release operation and a disk return operation, which are opposite to disk clamp operation and disk load-in operation described later, are performed. Will be returned to And
When the return of the disc is confirmed (step S1), the next target disc No. is taken in (step S2), and a selector move command is issued to bring the moving member 18 carrying the playing means to the designated position corresponding to the target disc. Emit (step
S3). Here, the selector is another name for the moving member 18 carrying the playing means.

After issuing the selector movement command, the control unit checks whether the current disk number is equal to the target disk number (step S4). If the current disk number is equal to the target disk number, if it is stored that the disk search operation has already been performed once and the search has been disabled, this stored content is immediately erased (step
S5) and cancel the selector movement command (step S5).
6). Next, the motor 62 is rotated so that the designated disk protrudes out of the magazine 5, and the moving body 56 (shown in FIG. 16 and the like) is driven backward (the direction opposite to the arrow Y direction).

At this time, the movable body 56 is moved by movable pieces 75 and 76 (see FIG. 16).
The second lever member 72 can be
And in the locked state. The first lever member 71 has not been locked with the moving body 56 yet. Therefore, the second lever member
Only 72 moves backward with the moving body 56, whereby the tray engaging member 53 rotates counterclockwise in FIG. Accordingly, as shown in FIGS. 2 (b) and 37 (a), a tray (for example, tray B12) holding the disk 10 to be played protrudes from the magazine body 8, and the disk is loaded on the disk of the turntable 23. It moves to a concentric position with respect to the surface 23a, that is, just below the disk carrying surface.

Thereafter, the moving body 56 moves further backward (the direction opposite to the direction of the arrow Y), but the second lever member 72 is unlocked from the moving body, and at the same time, the first lever member 71 is moved to the moving body. Locked against. Therefore, the first lever member 71 moves rearward together with the moving body 56, whereby the supports 78 and 79 (shown in FIG. 23 and the like) of the clamp mechanism swing upward (in the direction of arrow Z). Therefore, as shown in FIG. 37 (b), the disk 10 is lifted upward from the tray 12 by the clamp mechanism and clamped against the turntable 23, and the disk load-in operation is completed (step S).
7). Confirmation that the disk has been clamped on the turntable 23 is made by a detection signal generated when the detection switch 90 shown in FIGS. 6 and 11 is operated by the moving body 56.

Thus, the performance can be performed, and the control unit starts the servo system such as the spindle servo, the focus servo, and the tracking servo (step S8), reads the TOC information (step S9), and searches for the target music (step S1).
0), performance is started (step S11).

On the other hand, after issuing the selector movement command (step S3),
Even after a certain period of time (step S12), the current disc No.
Is not equal to the target disk No., that is, if the disk search operation is disabled, it is checked whether or not the disk search disabled state appears for the second time including this time (step S13).

Here, a description will be given of a situation that can be considered as a cause of such a disk search disabled state.

As shown in FIG. 38, when the tray 11 holding the disk 10 which has finished playing earlier is pushed by the disk engaging member 53 (shown in FIG. 9 and the like) and stored in the magazine body 8 of the magazine 5, It is conceivable that the frictional force between the magazine main body 8 and the tray is increased by the influence of finger grease or moisture attached to the tray 11, and the tray cannot be completely pushed into the magazine main body 8. In this case, the tray
A detection signal can be issued from the detection switch 89 for detecting the storage of the tray in the magazine main body 8 even though 11 is not completely stored in the magazine main body 8. That is, the tray engaging member 53 and the motor 62
Each member such as a plurality of driving force transmitting members for transmitting the driving force from the member is slightly deformed by the driving force, or the entire mechanism including the members is within the range of the accumulated value of the tolerance provided between the members. The tray engaging member is formed by a frictional force between the magazine body 8 and the tray 11 as shown in FIG.
Despite the fact that its rotation was prevented before 53 reached the position where the tray 11 was completely pushed into the magazine body 8, the moving body 56 for operating the detection switch 89 moved the actuator of the detection switch 89. You get.

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 disk 10 to be played next as described above, the moving member 18 is still outside the magazine body 8. The end of the moving member 18 and the components mounted on the moving member 18 abut against the tray 11 with a part protruding, and the moving member 18 is prevented from ascending, and the disk cannot be searched. .

If the above-mentioned occurrence of the disk search impossible state is the second time, the storage contents of the first disk inspection impossible state are erased (step S14) and the selector movement command is canceled (step S15). Then, the light emitting diode (LED) indicating that the disc is being played is turned off (step S16), and the operation is stopped.

On the other hand, if the appearance of the disk search impossible state is the first appearance in step S13, first, the fact that the disk search impossible state has occurred once is stored (step S17). Then, the current disk No. is compared with the target disk No. (step S18). If the target disk No. is higher than the current disk No., that is, the moving member 18 is currently raised (in the direction of arrow Z). If so, a selector move command is issued for a certain period of time to lower the moving member 18 slightly (steps S19, S20, S21). On the other hand, if the target disk number is lower than the current disk number and the moving member 18 is to be lowered, the selector is required to temporarily raise (UP) the moving member 18 once. A movement command is issued (steps S22, S20, S21). As described above, by temporarily driving the moving member 18 that has given the driving force to raise or lower the moving member 18 in the reverse direction, the moving member 18 As a result, the impact force is applied once. Therefore, the tray 11 holds the magazine body 8
You are released from the antagonistic state. Thereafter, a predetermined time elapses (step S23).
3 (shown in FIGS. 9 and 32 (a), (b)) is rotated clockwise in FIG. 9 to remove the tray 11 which has partially protruded out of the magazine body 8 as shown in FIG. It is completely stored in the magazine body 8. In this way, the tray 11 released from the antagonistic state due to the frictional force with the magazine body 8 can be used without pressing the tray 11 again by the disc engaging member 53.
Can be completely drawn into the magazine main body 8 by the urging force of the pressing lever 14 in the magazine main body 8 as shown in FIG. 2 (b).

As described above, the tray 11 is released from the antagonistic state with the magazine body 8 by temporarily moving the moving member 18 slightly in a direction opposite to the direction in which the moving member 18 is to be moved. Is returned to the lowest position as the home position until is issued (step S2
Four). Then, a detection signal from the photo sensor 51 is obtained (step S25), and after confirming that the moving member 18 has returned to the home position, the presence or absence of a STOP command is confirmed (step S26).
After that, the moving member 18 is moved to a designated position corresponding to the designated disc. The operation of positioning the moving member 18 at the designated position after returning to the home position and the subsequent performance start operation are performed along the above-described operation path (steps S4 to S11).

In addition, after issuing the selector movement command to return the moving member 18 to the home position, the detection signal from the photo sensor 51 indicating that the home position has been reached is not obtained even after a predetermined time has elapsed (step S27). Then, the operation from step S13 described above is repeated by setting this to a disk search disabled state. Hereinafter, the above operation is repeated according to the designated number of music pieces.

In this embodiment, a rack portion 37h is formed on the movable plate 37, and the double gear 40 meshed with the rack portion is formed.
By rotating the moving member 18, the moving member 18 is moved through the cam grooves 37d, 38d, thereby relative positioning of the magazine 5 serving as the disk storage portion and the playing means in the disk arrangement direction. , 38, a rack may be formed directly on the moving member 18 and a gear meshing with the rack may be driven to rotate.

Further, in this embodiment, a case is shown in which the frictional force generated between the magazine main body 8 of the magazine 5 and each of the trays 11 and 12 is increased and the tray is not completely accommodated in the magazine main body 8. In a player having a disk storage section having a plurality of disk storage shelves for directly storing disks without having such trays 11 and 12, even when the frictional force generated between the disk storage section and the disk increases. The same is true.

Effects of the Invention As described in detail above, the multiple disk storage player according to the present invention includes: a disk storage unit capable of arraying and storing a plurality of disks; and a positioning unit that relatively moves and positions the playing unit in the disk array direction; A disk moving means for moving a disk between the disk storage part and the playing means, wherein the positioning means comprises a movable member carrying one of the disk storage part and the playing means; A drive mechanism for moving the movable member; and control means for issuing the movement command to the drive mechanism until the performance means is positioned with respect to a disk storage position corresponding to the disk specified by the performance command. The control means issues a movement command in one direction to the drive mechanism, and then controls the disk storage position. When it is detected that a predetermined time has elapsed before the performance means is positioned with respect to the position, a movement command is issued to the drive mechanism in a direction opposite to the one direction. .

That is, for example, the frictional force between the disc storage section and the disc to be stored in the disc storage section or the tray holding the disc becomes large, and the disc that has finished playing cannot be completely stored in the disc storage section. A state in which the disk or a part of the tray is still protruding out of the disk storage portion occurs, and the movable member or the mounted component engages with the disk or the tray to move the playing means relative to the disk storage portion. Is stopped, the movable member is once moved in the direction opposite to the direction in which it is to be moved to release this engaged state.
By this series of engagement and disengagement operations, the same state occurs as if a striking force was once applied to the disk or tray that was in an antagonistic state with the disk storage section due to frictional force, and the disk or tray was stored in the disk storage section. The disk is released from the state of antagonism with the disk storage unit, and thereafter the disk is smoothly stored in the disk storage unit by the action of the disk moving unit and the urging unit provided in the disk storage unit for pulling in the disk.

Therefore, the occurrence of the disk search impossible state due to the incomplete storage state of the disk in the disk storage section is avoided,
The continuous performance of a plurality of discs is smoothly performed.
