Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording medium playback apparatus, and is particularly suitable for application to a playback apparatus configured to selectively play back a desired recording medium from among a plurality of stored recording media.
[0002]
[Prior art]
Conventionally, for example, Japanese Utility Model Laid-Open No. 62-195257 discloses a disk reproducing apparatus that selectively reproduces a desired disk from a plurality of disc-shaped recording media (hereinafter referred to as disks). As described above, there is a method in which a plurality of discs are stored in a stocker that is detachable from the disc playback device, and the stocker is attached to the disc playback device.
[0003]
However, according to this method, the stocker has to be attached and detached each time the disk is replaced, which causes a problem of poor operability.
As one method for solving this problem, as disclosed in, for example, Japanese Patent Laid-Open No. 3-83263, a stocker storing a plurality of sub-trays for holding a disk is provided in the disk reproducing apparatus and the disk is mounted. Some have a main tray for taking in and out.
[0004]
That is, as shown in FIG. 15, in the disk reproducing apparatus 1, the main tray 5 is slidable in the direction indicated by the arrow k and in the opposite direction to the sliding portions 3A and 3B of the base 3 on which the optical pickup 2 is mounted. Is held in. Therefore, by sliding the main tray 5 along the sliding portions 3A and 3B, the main tray 5 can be swept from the disk insertion port 6A provided in the housing 6 to the loading and unloading position 11A. The optical pickup 2 can be pulled into the reproduction position 11B where the optical pickup 2 is provided.
[0005]
A plurality of sub-trays 13A are stored in the vertical direction in the stocker 12 at the deepest portion when viewed from the disk insertion opening 6A, and a desired sub-tray is selected from the sub-tray 13A by moving the stocker 12 up and down. By moving this in the direction opposite to the direction indicated by the arrow k, the sub-tray 13A is moved to the reproduction position 11B.
[0006]
In this state, by holding the disk placed on the sub-tray 13A on a predetermined turntable (not shown), the disk is driven to rotate, and the light beam from the optical pickup is applied to the recording surface of the disk. To reproduce the information recorded on the recording surface.
[0007]
When the disk at the reproduction position 11B is swept out from the disk insertion opening 6A to the outside (ie, loading and unloading position), the sub-tray 13A is placed on the main tray 5 at the reproduction position 11B, and further on the sub-tray 13A. The main tray 5 is swept out from the disk insertion slot 6A to the loading / unloading position 11A with the disk placed.
[0008]
[Problems to be solved by the invention]
However, in such a method, when the subtray 13A is moved from the stocker 12 to the loading / unloading position 11A, the subtray 13A is placed on the main tray 5 at the reproduction position 11B, and then the main tray 5 is moved to the subtray 13A. At the same time, since the main tray 5 is used, the configuration of the disk reproducing apparatus 1 is complicated and the size of the disk reproducing apparatus 1 is increased as a whole.
[0009]
The present invention has been made in consideration of the above points, and an object of the present invention is to propose a recording medium reproducing apparatus that can further improve the operability and can be downsized with a simple configuration.
[0010]
[Means for Solving the Problems]
In order to solve such a problem, in the present invention, a stocker 31 capable of storing a plurality of recording media DISK in each storage position, a reproducing means 90 for reproducing the recording medium DISK, an elevating means 32 for moving the stocker 31 up and down, A reproduction position at which the recording medium DISK is reproduced by the reproduction means 90 and an insertion / removal position of the recording medium DISK provided at a side substantially opposite to the reproduction position and facing the reproduction means 90 with respect to the stocker 31. When the recording medium DISK is transported between the insertion / removal position and the reproduction position via the transfer means 68 for transferring the recording medium DISK and the storage position selected in the stocker 31, the selected storage position And a control means 120 for controlling the elevating means 32 so as to be arranged on the transfer path of the transfer means 68.
[0011]
As a result, when the recording medium playback apparatus 30 transports the recording medium DISK between the insertion / removal position and the playback position, which are substantially the same height, via the stocker 31 in which a plurality of recording media DISK are stored, the stocker The lifting / lowering means 32 can be controlled so that the selected storage position in 31 is arranged on the transfer path of the transfer means 68. Thus, when the selected recording medium DISK is reproduced, the recording medium DISK is used as an apparatus. When inserted from the outside and transferred to the regeneration position via the stocker 31, it can be reliably transferred to the regeneration position without being blocked in the stocker 31.
[0012]
In the present invention, the storage position arranged on the transfer path of the transfer means 68 is a storage position where the recording medium DISK is not stored.
[0013]
As a result, in the recording medium reproducing apparatus 30, the recording medium DISK inserted into the apparatus can surely pass the storage position arranged on the transfer path and reach the reproducing position.

A pin 98 engaged with the distal end portion of the moving arm 97 is moved up and down.
[0039]
Accordingly, in FIG. 9, the moving movement in the direction indicated by the arrow f of the base 91 with respect to the positioning hole 42H of the tray 42 selected from the plurality of trays 42 to 46 and moved to the reproduction position on the optical pickup 90 is shown. By inserting the pins 98 according to the above, the tray 42 can be positioned and the tray 42 can be prevented from inadvertently moving in the direction indicated by the arrow b or in the opposite direction.
[0040]
Thus, in this state, the turntable 110 provided on the base 91 presses the disk DISK mounted on the tray 42 with the disk presser 112 (FIG. 9), thereby rotating the turntable 110. Thus, the disk DISK can be driven to rotate. At this time, information can be read from the rotating disk DISK by irradiating the recording surface of the disk DISK mounted on the tray 42 with a light beam from the optical pickup 90 of the base 91.
[0041]
When the reproducing operation is further completed, the transition end 91B of the base 91 is moved in the direction opposite to the arrow f direction (that is, downward) by sliding the slide cam 95 in the direction opposite to the direction indicated by the arrow e (FIG. 10). To do. Thus, by sliding the slide cam 95 to the end of the slide area, the transition end 91B of the base 91 shifts to the lowermost part. Accordingly, in this state, the turntable 110 of the base 91 is simultaneously moved to the lowermost position, thereby opening the disk DISK mounted on the tray 42 and the pins 98 (FIG. 9) of the sub-tray 42. The tray 42 is removed from the positioning hole 42H, and the tray 42 is moved to the position of the stocker 31 in this state.
[0042]
Here, as shown in FIG. 11, the disk reproducing apparatus 30 is provided with a control circuit 120. A drive circuit 121 for driving the stocker 31 up and down based on a control signal S10 from the control circuit 120 is provided. Drive control is made.
[0043]

[0044]
The control circuit 120 is configured to drive each tray 42, 43, 44, 45 or 46 along the slide bearing 63 by sending a control signal S 12 to the drive circuit 122.
[0045]
Further, the sliding position of the tray 42, 43, 44, 45 or 46 when the tray 42, 43, 44, 45 or 46 is driven along the sliding bearing 63 is provided along the sliding bearing 63. When the position detection signals S13, S14, and S15 from the three position detection elements 66A, 66B, and 66C are input to the control circuit 120, the control circuit 120 can detect them.
[0046]
Further, the control circuit 120 sends a control signal S16 to the drive circuit 123 so as to move up and down the transition end 91B of the base 91 on which the optical pickup 90 is mounted.
[0047]
The position of the transition end 91B when the transition end 91B of the base 91 on which the optical pickup 90 is mounted is moved up and down is a position output from the position detection element 67 that detects the position of the slide cam 95. Detection is performed by inputting the detection signal S17 to the control circuit 120, and the control circuit 120 controls driving of the drive circuit 123 based on the detection result.

(2) Operation of the embodiment
In the disk reproducing apparatus 30, the trays 42, 43, 44, 45, and 46 can move at a height P corresponding to the disk insertion port 41. This position is a position where the sliding bearing 64 is held.
[0049]
First, when a disk is not stored in the disk playback apparatus 30, the disk DISK is placed on any tray 42 to 46 and stored in the disk playback apparatus 30.
[0050]
That is, for example, when a disk is placed on the tray 44 and stored in the disk reproducing device 30 (FIG. 12A), the control circuit 120 (FIG. 11) is driven by a motor via the drive circuit 121 according to a required operation. The stocker 31 is moved in the direction of arrow a by driving M1 and rotating the cam 61 (FIGS. 4 and 5). Then, the position detection signal S11 from the rotary encoder 65 (FIG. 11) detects that the tray 44 has reached the transportable position P. At this time, the control circuit 120 stops the movement of the stocker 31. At this time, the engaging portion 44B fixed to the tray 44 and the engaging protrusion 64A provided on the sliding bearing 64 are engaged (FIG. 12B).

Next, an operation of reproducing the disk DISK placed on any trays 42 to 46 will be described. That is, as shown in FIG. 13, for example, when the disk DISK placed on the tray 44 is reproduced (FIG. 13A), the control circuit 120 passes the motor M <b> 1 via the drive circuit 121 according to a required operation. And the cam 61 is rotated to move the stocker 31 in the direction of arrow a (FIG. 5). Then, the position detection signal S11 from the rotary encoder 65 detects that the tray 44 has reached the transportable position P. At this time, the control circuit 120 stops the movement of the stocker 31.
[0054]
At this time, the engaging portion 44B provided on the tray 44 is engaged with the engaging protrusion 64A of the sliding bearing 64 (FIG. 13B). After the stocker 31 stops at a predetermined position, the control circuit 120 drives the motor M2 via the drive circuit 122 and moves the sliding bearing 64 (FIG. 6) in the direction indicated by the arrow b. When the position detecting element 66C (FIG. 6) detects that the sliding bearing 64 has arrived, the movement of the sliding bearing 64 is stopped (FIG. 13C).
[0055]
After the sliding bearing 64 stops at a predetermined position, the control circuit 120 drives the motor M3 via the drive circuit 123 and moves the slide cam 95 (FIG. 9) to move the base 91 on which the optical pickup is mounted. Move in the direction indicated by arrow f. Then, when the position detecting element 67 detects that the base 91 has reached the reproduction position, the slide cam 95 is stopped. In this state, the disk DISK placed on the tray 44 can be reproduced (FIG. 13D). With the same operation as described above, the disk DISK placed on any disk tray 42 to 46 can be reproduced.
[0056]
Next, the operation of playing back a disk DISK placed on a different tray from the disk DISK placed on any tray 42 to 46 at the current playback position will be described. That is, as shown in FIG. 14, for example, when playing back a disk DISK placed on another tray 45 (FIG. 14A) when playing back the disk DISK placed on the tray 42, it is necessary. In response to the operation, the control circuit 120 drives the drive source M3 through the drive circuit 123 and moves the slide cam 95 to move the base 91 on which the optical pickup 90 is mounted in the direction opposite to the direction indicated by the arrow f. To do. Then, when the position detecting element 67 detects that the base 91 has reached the position for canceling the reproduction, the slide cam 95 is stopped (FIG. 14B).
[0057]
After the slide cam 95 stops, the control circuit 120 drives the motor M2 via the drive circuit 122 and moves the slide bearing 64 in the direction indicated by the arrow b. Then, when it is detected that the sliding bearing 64 has arrived at the position detection element 66B (FIG. 6), the movement of the sliding bearing 64 is stopped (FIG. 14C). After the sliding bearing 64 stops at a predetermined position, the control circuit 120 drives the motor M1 through the drive circuit 121 and rotationally drives the cam 61 (FIG. 4), thereby moving the stocker 31 in the direction indicated by the arrow a.

Then, when the tray 45 reaches the transportable position P by the position detection signal S11 from the rotary encoder 65, the movement of the sliding bearing 64 is stopped. At this time, the engaging portion 42B provided on the tray 45 is engaged with the engaging protrusion 64A of the sliding bearing 64 (FIG. 14D). After the stocker 31 stops at a predetermined position, the control circuit 120 drives the motor M2 through the drive circuit 122, and moves the sliding bearing 64 in the direction indicated by the arrow b (FIG. 14E). When the position detection element 66C detects that the slide bearing 64 has arrived, the control circuit 120 drives the motor M3 via the drive circuit 123 and moves the slide cam 95 (FIG. 8) to move the base 91. When it is detected that has reached the reproduction position, the movement of the slide cam 95 is stopped. In this state, the disk DISK placed on the tray 45 can be reproduced (FIG. 14F).
[0059]
The disk DISK placed on another tray 42 can be played back during playback of the disk DISK placed on any of the disk trays 42 to 46 by the same operation as described above. Next, an operation of taking out the disk DISK placed on another tray 42 during the reproduction of the disk DISK placed on an arbitrary tray will be described. That is, as shown in FIG. 15, for example, when the disk DISK placed on the tray 45 is taken out during the reproduction of the disk DISK placed on the tray 42 (FIG. 15A), according to the required operation. The control circuit 120 drives the motor M3 through the drive circuit 123 and moves the slide cam 95 (FIG. 5), thereby moving the base 91 in the direction opposite to the direction indicated by the arrow f. When the control circuit 120 detects that the base 91 has reached the reproduction release position based on the position detection signal S17 from the position detection element 67, the control circuit 120 stops the movement of the slide cam 95 (FIG. 15B). .
[0060]
After the slide cam 95 stops, the control circuit 120 drives the motor M2 via the drive circuit 122, and moves the slide bearing 64 in the direction opposite to the direction indicated by the arrow b. When the position detection element 66B detects that the sliding bearing 64 has arrived, the movement of the sliding bearing 64 is stopped (FIG. 15C). After the sliding bearing 64 stops at a predetermined position, the control circuit 120 drives the motor M1 via the drive circuit 121 and rotationally drives the cam 61 (FIG. 4), thereby moving the stocker 31 in the direction indicated by the arrow a.

Can be stored, and the desired disk DISK can be reproduced from the disks DISK stored in the stocker 31.
[0064]
Further, when taking out the disk DISK, a desired disk DISK can be swept out from the disk insertion port 41 out of the plurality of disk DISKs stored in the stocker 31.
Further, a desired disk DISK can be moved from the plurality of disks DISK stored in the stocker 31 to the reproduction position.
[0065]
In the disk reproducing apparatus 30, a disk DISK loading / unloading unit and a reproducing unit are provided before and after the stocker 31, and trays 42 to 46 accommodated in the stocker 31 are slid in the front-rear direction of the stocker 31. As a result, the moving distance of the trays 42 to 46 from the stocker 31 can be shortened as compared with the conventional case in which a reproducing unit is provided between the loading / unloading unit and the stocker 31.
[0066]
Therefore, the trays 42 to 46 can be directly moved to the loading and unloading positions of the disk outside the disk reproducing apparatus 30 without using the main tray as in the prior art, and the configuration of the disk reproducing apparatus 30 is simplified accordingly. Therefore, the disk reproducing device 30 can be downsized as a whole.
[0067]
(3) Effects of the embodiment
According to the above configuration, the disk DISK can be stored in the disk playback device 30 by a simpler operation method, and a desired disk can be selected from the disk DISK stored in the stocker 31 and played back. Can do.
[0068]
Further, the trays 42 to 46 can be directly moved from the disk insertion port 41 to the outside (loading and unloading positions) of the disk reproducing device 30, and the configuration of the disk reproducing device 30 can be simplified correspondingly. The overall size can be reduced.
[0069]
(4) Other embodiments
In the above-described embodiment, the case where the stocker 31 having the five trays 42 to 46 is used as a tray for storing the disk DISK has been described. However, the number of trays is not limited to this, and a plurality of trays are important. Therefore, any disk reproducing apparatus that stores a plurality of disk DISKs and selectively reproduces them may be used.
[0070]
Further, in the above-described embodiment, the case has been described in which a disk that is optically read out of recorded information is used as a disk to be played back by the disk playback device 30, but the present invention is not limited to this, and other The present invention is suitable for application to a reproducing apparatus that reproduces various recording media.
[0071]
【The invention's effect】
As described above, according to the present invention, a stocker capable of storing a plurality of recording media in each storage position, a reproducing means for reproducing the recording medium, an elevating means for moving the stocker up and down, and a reproducing means for reproducing the recording medium. Transport means for transporting the recording medium between the reproducing position to be performed and the insertion / removal position of the recording medium provided on the side opposite to the reproducing means with respect to the stocker at substantially the same height as the reproducing position; When transporting the recording medium between the insertion / removal position and the reproduction position via the storage position selected in the stocker, the lifting / lowering means is arranged so that the selected storage position is arranged on the transfer path of the transfer means. By providing a control means for controlling, when reproducing the selected recording medium, when the recording medium is inserted from the outside of the apparatus and transferred to the reproduction position via the stocker, the transfer at the stocker is prevented. Can be reliably transferred to the reproducing position without, thus further together can improve the operability can be realized a simple structure and a recording medium reproducing apparatus capable of downsizing.
