DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment to which the present invention is applied will be described with reference to the drawings.
[0007]
FIG. 1 is a plan view of a principal part showing an initial state in which no disc is accommodated in a changer type disc reproducing apparatus 1 capable of accommodating 6 discs. On the back side of the apparatus, arcuate disk holders 11 to 16 are disposed so as to sandwich the disk over an angular range of about 180 degrees out of the periphery of the 12 cm disk. Since the disc is clamped by the disc holders 11 to 16 only at the peripheral edge of the disc, even if the disc holder 11 to 16 is damaged, the influence on the information recorded on the disc is minimal. It is configured to In FIG. 1, only the first disk holder 11 located at the top of the disk holders 11 to 16 is shown.
[0008]
The disk holder 11 is provided with four flanges 19, and a round hole 17 is formed in each of the flanges 19. An engagement pin 18 (described later) protrudes from the round hole 17, and the engagement pin 18 is a cam member 30 (described later) for moving the disc holder 11 in a direction perpendicular to the paper surface direction of FIG. 1. It fits into the cam groove 33 formed in the above. The other disk holders 12 to 16 have the same configuration as the disk holder 11, and the flange 19, the round hole 17, and the engagement pin 18 are similarly formed.
[0009]
FIG. 10 is a side view of the cam member 30. A cam groove 33 is formed on the surface of the substantially cylindrical cam member 30 having a length L30. Referring to FIG. 11, which is a cross-sectional view taken along the line AA in FIG. 10, a hexagonal center hole 31 is formed at the center of the cam member 30. A supported hexagonal rotating shaft 32 is inserted. Therefore, when the rotating shaft 32 rotates, the cam member 30 rotates in the same manner, and the cam member 30 can be translated in the axial direction of the rotating shaft 32.
[0010]
A position P30 that intersects the cut surface along the line AA in the cam groove 33 is a place where a disc holder corresponding to the disc is located when the disc is reproduced. The cam groove 33 is not fitted to the engagement pins 18 of all the disk holders 11 to 16, but is adapted to move the disk holder to be reproduced to the cam groove 33 and move it to the reproduction position P30. Other disk holders are located above or below the cam member 30.
[0011]
Of the disc holders located on the upper side of the cam member 30, the engaging pin 18 of the disc holder adjacent to the cam member 30 abuts on the upper surface of the cam member 30 to hold the position, and the disc located further on the upper side. The holder is stacked on the disk holder that is in contact with the upper surface of the cam member 30. Of the disk holders located on the lower side of the cam member 30, the disk holders adjacent to the base chassis 3 have four mounting portions 36 provided on the base chassis 3 so as to abut each of the flanges 19. The disk holder that is placed on and located between the disk holder and the cam member 30 is stacked on the disk holder that is placed on the placement portion 36.
[0012]
The rotation shaft 32 is provided with a spur gear 34, and the rotation direction and rotation position of the cam member 30 are controlled by a required cam member drive mechanism 82 including a motor, a reduction gear mechanism, and the like. The four cam members 30 are rotationally driven in the same direction at the same rotation angle by connecting the spur gears 34 to each other.
[0013]
20 is a cross-sectional view of the disk holder 11 shown in FIG. The disc holder 11 includes a base portion 21 and upper and lower guide plates 22 and 23 that are provided on the base portion and sandwich the disc. On the other hand, in the range J at the right end portion of the disc holder 11 (see FIG. 1), an elastomer 24 is provided as a high friction member at a portion of the base portion 21 that contacts the disc periphery, and a sectional view of this portion is shown in FIG. Show.
[0014]
In FIG. 1, as a disk transfer means for transferring a disk inserted from an opening (not shown) formed in the front panel 2 of the apparatus 1 to the reproduction position or the disk holders 11 to 16, on the left side in FIG. A disc drive mechanism 40 composed of a plurality of drive rollers and the like, and guide means 50 for clamping the disc between the disc drive mechanism 40 on the right side are arranged. The disk drive mechanism 40 is formed with a V-shaped groove on its peripheral surface so as to sandwich the periphery of the disk, and connects the four drive pulleys 41 to 44 arranged in the disk transfer direction and the drive pulleys 41 to 44. And a required pulley drive mechanism 84 which is connected to the gears 45 to 47 and the gear 45 and includes a motor or the like for rotationally driving the drive pulleys 41 to 44.
[0015]
On the other hand, the guide means 50 is arranged between a pair of upper and lower guide plates 51 and 52 formed so as to hold the peripheral edge of the disc, and a guide wall 53 arranged between the guide plates 51 and 52 and against which the disc edge abuts. It consists of. The disk drive mechanism 40 and the guide means 50 can be moved in parallel in the direction of the arrow D-E in FIG. 1 by a required connecting mechanism (not shown), and the guide means 50 can be moved by the required distance in the direction of the arrow E. In this case, the disk drive mechanism 40 is connected so as to move by the same distance in the direction of the arrow D opposite thereto. In order to move the disk drive mechanism 40 and the guide means 50 in the direction of the arrow D-E, a necessary pulley / guide drive mechanism 85 such as a motor is provided.
[0016]
Therefore, when the drive pulley 41 is driven to rotate counterclockwise by the pulley drive mechanism 84 in a state where the disc is sandwiched between the drive pulley 41 and the guide wall 53 arranged closest to the front panel 2, the disc Is transferred while rotating clockwise in the direction of the arrow F perpendicular to the direction of the arrow D-E, so that it is transferred from the opening formed in the front panel 2 to the reproduction position or the selected disc holder.
[0017]
As shown in FIG. 1, the four drive pulleys 41 to 44 are arranged at a certain distance from each other in the disc transfer direction. Accordingly, when the center of the disk is positioned on the straight line connecting the rotation center of the drive pulleys 41 to 44 and the guide wall 53 during the transfer of the disk, the distance between the disk drive mechanism 40 and the guide means 50 is increased. When the center of the disk is positioned on a straight line connecting the intermediate points of the drive pulleys 41 to 44 and the guide wall 53 with the shortest distance, the separation distance between the disk drive mechanism 40 and the guide means 50 is as follows. Minimal. Therefore, the distance between the disk drive mechanism 40 and the guide means 50 is constantly changed during the transfer of the disk, but the displacement is such that the transfer of the disk is not affected.
[0018]
In the state where the disc is brought to the reproduction position, the protrusions 54 and 55 are formed at equal intervals from the position where the guide wall should be in contact with the disc. Further, at this regeneration position, the drive pulleys 43 and 44 are similarly arranged at equally spaced positions. Accordingly, the disk at the reproduction position is stably supported by the protrusions 54 and 55 and the drive pulleys 43 and 44.
[0019]
Further, an actuator portion of a detection switch for detecting that the disk has been brought to the reproduction position protrudes from the tip of the protrusion 54 (not shown).
[0020]
The drive pulleys 41 and 42 disposed on the front panel 2 side corresponding to the protrusions 54 and 55 are slightly on the guide means 50 side with respect to the drive pulleys 43 and 44 disposed on the disk holders 11 to 16 side. Are arranged so as to be close to each other.
[0021]
As shown in FIG. 7, which is a front view corresponding to FIG. 1, the turntable 61 on which the disk is placed is rotationally driven by a spindle motor 62 and is disposed on a mechanical chassis 63. A clamper 71 is rotatably supported by a clamp arm 72 so as to clamp the disk between the turntable 61. The clamp arm 72 is rotatably supported by the mechanical chassis 63 by a shaft 73 so that the clamper 71 can approach or be separated from the turntable 61.
[0022]
Since the bending portion 74 is formed in the clamp arm 72 as shown in FIG. 7, when the guide means 50 moves to a position separated from the disk, a sufficient separation distance from the clamper arm 72 can be obtained. .
[0023]
On the mechanical chassis 63, there is disposed an optical pickup 66 that can move between the inner periphery and the outer periphery of the disk in accordance with the rotation of a feed screw 65 that is rotationally driven by a required motor (not shown). . The reproduction of the information recorded on the disc is achieved by irradiating the disc with laser light emitted from the optical pickup 66 while reading the reflected light while rotating the disc by the turntable 61, and at least turning the disc. The table 61 and the optical pickup 66 constitute a reproducing means.
[0024]
A guide rail 67 is provided on the mechanical chassis 63 so that the optical pickup 66 moves in parallel, and guides the movement of the optical pickup 66. The mechanical chassis 63 can be translated in the direction of arrow FG in FIG. 1 by a mechanical chassis drive mechanism 86 made of a motor or the like, and can be moved in a direction perpendicular to the recording surface of the disk for the clamping operation. Further, during the clamping operation, when the mechanical chassis 63 moves in the direction approaching the recording surface of the disk, the clamper arm 72 is also rotated around the shaft 73 so as to be close to the turntable 61 by a coupling mechanism (not shown).
[0025]
Here, as shown in FIG. 7, the mechanical chassis 63 is supported by the movable chassis 10 by a damper 91, and the disk drive mechanism 40 and the guide means 50 are directed to the movable chassis 10 in the direction D-E shown in FIG. 1. Is supported so as to be movable. The movable chassis 10 moves up and down with respect to the base chassis 3 in accordance with the selection of the disk. Further, as described above, the rotating shaft 32 of the cam member 30 that supports the disk holders 11 to 16 so as to be movable up and down is supported on the base chassis 3.
[0026]
In the above configuration, the disk transfer by the disk transfer means will be described first. As shown in FIGS. 1 and 7, in the initial state in which the disc can be inserted, the distance between the first drive pulley 41 arranged closest to the front panel 2 and the guide wall 53 of the guide means 50 is 8 cm in diameter. It is set to be slightly smaller than the diameter of the disc. In this initial state, as shown in FIG. 10, the engagement pin 18 formed on the first disk holder 11 is located at a position P30 in the cam groove 33 formed on the cam member 30, and the second to second The six disk holders 18 are stacked on a holder mounting portion 36 provided in the movable chassis 10.
[0027]
Hereinafter, an operation when the disk 101 having a diameter of 12 cm is inserted into the apparatus 1 will be described. When the disc 101 is inserted from an opening (not shown) formed in the front panel 2, the disc drive mechanism 40 is moved in the direction of arrow D by this insertion force, and the guide means 50 is moved in the direction of arrow E by the same distance. The state shown in FIG. 2 is obtained. Thereafter, the drive pulleys 41 to 44 are each driven to rotate counterclockwise by the pulley drive mechanism 84, whereby the disk 101 held between the drive pulley 41 and the guide wall 53 rotates in the clockwise direction in the direction of arrow F. And loaded into the apparatus 1.
[0028]
When the disc 101 is inserted, the disc drive mechanism 40 and the guide means 50 are movably supported by the movable chassis 10. Therefore, the operator can obtain a rigid insertion feeling without being affected by the damper 91.
[0029]
A state in which the disk 101 is moved to the reproduction position by the rotation of the drive pulleys 41 to 44 is shown in FIG. 3 and FIG. 8 which is a front view thereof. At this reproduction position, the disc 101 is not in contact with the disc holder 11 aligned at the same height.
[0030]
Subsequently, the mechanical chassis drive mechanism 86 moves the mechanical chassis 63 in a direction perpendicular to the recording surface of the disk 101 so as to be close to the disk 101, and the clamper 71 is moved so as to be close to the disk 101, whereby the disk is placed on the turntable 61. After clamping 101, the pulley / guide drive mechanism 85 moves the disk drive mechanism 40 and the guide means 50 in the directions of arrows D and E, respectively, thereby separating them from the disk 101. Thereafter, the disk 101 is rotationally driven at a required number of revolutions, and this reproduction state is shown in FIG. 4 and FIG. 9 which is a front view thereof. Note that this reproduction position is the same height as the transfer plane of the disk 101.
[0031]
The clamp arm 72 is supported by a base chassis 63 supported on the damper 91. On the other hand, the guide means 50 is supported on the base chassis 3. Accordingly, in the reproduction state shown in FIG. 9, the clamp arm 72 is moved by vibration, but a sufficient distance from the guide means 50 is provided by the bent portion 74 formed on the clamp arm 72. Therefore, since the clamp arm 72 can be brought close to the disk 101, it can contribute to downsizing of the apparatus in the height direction.
[0032]
An operation of storing the disc 101 in the disc holder 11 and storing a different disc in the second disc holder 12 after the reproduction of the disc 101 will be described below. After the reproduction of the disk 101 is finished, the disk 101 is moved to the drive pulleys 43 and 44 and the guide wall 53 by moving the disk drive mechanism 40 and the guide means 50 in the directions of arrows E and D by the pulley / guide drive mechanism 85, respectively. After the gripping, the mechanical chassis 63 and the clamper 71 are moved away from the disk 101 by the mechanical chassis drive mechanism 86, and the clamped state of the disk 101 is released.
[0033]
Subsequently, the drive pulleys 41 to 44 are rotated counterclockwise by the pulley drive mechanism 84 and the disk 101 is moved in the direction of arrow F, so that the range of about 180 degrees on the periphery of the disk 101 is held by the disk holder 11. This state is shown in FIG.
[0034]
Next, the mechanical chassis 63 is moved in the direction of arrow G by the mechanical chassis drive mechanism 86, and the mechanical chassis 63 is brought to a retracted position where it does not overlap the disk 101 held by the disk holder 11. Thereafter, the drive pulley 44 and the guide wall 53 are separated from the peripheral edge of the disk 101 by moving the disk drive mechanism 40 and the guide means 50 in the directions of arrows D and E, respectively, by the pulley / guide drive mechanism 85. This state is shown in FIG.
[0035]
Subsequently, in order to select the disc holder 12, the cam member 30 is rotated by the cam member drive mechanism 82, and the movement of the disc holders 11 to 16 by the cam member 30 is controlled in the vertical movement of the disc holders 11 to 16. FIG. 12 is a side view of the cam member 30 to be described, and will be described with reference to FIGS.
[0036]
FIG. 12 shows a state where the first disc holder 11 is selected. In this state, the first disc holder 11 is located at the reproduction position P30 (see FIG. 10) in the cam groove 33 formed in the cam member 30. The second to sixth disc holders 12 to 16 are stacked on the holder mounting portion 36, but only the engaging pin 18 of the second disc holder 12 is fitted at the lowermost side of the cam groove 33. Yes. In this state, the cam member 30 is supported by the disc holder 12 by the cam groove 33 coming into contact with the engagement pin 18 of the disc holder 12.
[0037]
Note that the interval L33 between the disc holders 11 and 12 is an interval at which the mechanical chassis 63 on which the turntable 61, the optical pickup 66, etc. are placed can be inserted when the disc 71 is reproduced as shown in FIG. . The interval L32 is an interval at which the clamper 71 and the clamper arm 72 can be inserted. L31 indicates a range in which the disk holders 11 to 16 move up and down according to the selection of the disk.
[0038]
That is, the length L30 of the cam member 30 is substantially equal to the length required to provide the distances L32 and L33 required above and below the disc when the disc is reproduced, and the distance L31 is the length of the cam member. It is approximately equal to the length obtained by adding the thickness obtained by stacking six disc holders to the length L30.
[0039]
The operation when the cam member 30 is rotated clockwise to store the second disk in the disk holder 12 will be described below. When the cam member 30 is slightly rotated clockwise from the position shown in FIG. 12, the cam member 30 moves downward along the cam groove 33 simultaneously with the rotation, and becomes the position shown in FIG. When the cam member 30 further rotates in the clockwise direction from this state, the lower side of the cam member 30 comes into contact with the engagement pin 18 of the third disc holder 13, so that the cam member 30 cannot move further downward. It rotates while maintaining the height shown in FIG. As a result, the disc holder 12 is moved upward along the cam groove 33 in the drawing. On the other hand, the disc holder 11 is similarly moved upward along the cam groove 33. This moving state is shown in FIG.
[0040]
FIG. 15 shows a state in which the cam member 30 is further rotated in the clockwise direction while being held by the engagement pin 18 of the disc holder 13. When the cam member 30 further rotates clockwise from this position, the engaging pin 18 of the disc holder 13 is inserted into the cam groove 33, so that the cam member 30 moves downward while rotating along the cam groove 33. . On the other hand, the engagement pin 18 of the first disc holder 11 is detached from the cam groove 33 and supported by the upper surface of the cam member 30. Further, the second disk holder 12 is positioned at the reproduction position P30 in the cam groove 33 so that the second disk can be loaded or reproduced. This state is shown in FIG.
[0041]
Therefore, in the playback state of the disk stored in the first disk holder 11 shown in FIG. 12 and the playback state of the disk stored in the second disk holder 12 shown in FIG. The height of the disc to be played is different. Accordingly, the mechanical chassis 63 also moves up and down in the same manner, but detailed description thereof is omitted.
[0042]
When the third disc holder 13 is stored in the third disc holder 13, the cam member 30 further rotates clockwise from the second disc reproduction state shown in FIG. When the pin 18 is further inserted into the cam groove 33, the cam member 30 slightly moves downward while rotating along the cam groove 33. As a result, the lower end of the cam member 30 comes into contact with the engagement pin 18 of the fourth disk holder 14 and can no longer move downward, and the cam member 30 rotates while maintaining the height shown in FIG. . As a result, the disc holder 13 is moved upward along the cam groove 33 in the figure. On the other hand, the disc holder 12 similarly moves upward along the cam groove 33, and the third disc holder 13 is brought to the reproduction position as shown in FIG.
[0043]
Similarly, when the cam member 30 rotates three times in the clockwise direction from the state shown in FIG. 18, the disc holder 16 is moved to the reproduction position P30 on the cam member 30 as shown in FIG.
[0044]
The operation of pulling out the disk 101 stored in the disk holder 11 is the reverse of the above description of transferring the disk from the playback position to the disk holder 11. That is, for the transfer of the disk, the disk 101 is first held by the drive pulley 44 and the guide wall 53 with respect to the disk 101 accommodated in the disk holder 11. Therefore, the angle range in which the drive pulley 44 and the guide wall 53 contact the disk 101 is less than 180 degrees. Therefore, the holding force is smaller than that at 180 degrees.
[0045]
FIG. 5 is the same as the state in which the disk 101 is started to be pulled out from the disk holder 11. 5, the point where the drive pulley 44 contacts the disk 101 is denoted by C1, the center of the disk 101 is denoted by O, and the intersection of the straight line passing from C1 to the center O and the disk holder 11 is denoted by C2.
[0046]
When the drive roller 44 and the guide wall 53 are strictly sincerely with respect to the disc holder 11, this clamping force is applied to the disc holder 11 when the disc 101 is held between the drive roller 44 and the guide wall 53. On the other hand, nothing is added in the direction of the arrow D-E. However, when the disc holder 11 is slightly offset in the direction of arrow D by about 0.5 mm, the holding force by the drive pulley 44 is transmitted to the intersection C2 via the disc 101.
[0047]
Here, as shown in FIG. 1, an elastomer 24 that is a high friction part is provided in a range J including the intersection C <b> 2, and the disk 101 is pressed against the elastomer 24 by the driving pulley 44. It is possible to rotate 101 without slipping and pull it out from the disc holder 11.
[0048]
In the above-described embodiment, when the disk is played back or when the disk is loaded, the position of the disk holder that holds the disk with respect to the cam groove 33 is the same, but the cam member 30 depends on the selection of the disk. Moves up and down, so that the height of the reproduction disk with respect to the movable chassis 10 is different. Therefore, the opening formed in the front panel 2 is required to have at least a height that extends over the height positions of the disk holders 11 and 16 shown in FIGS. 12 and 19. By providing, it is possible to prevent entry of dust and the like.
[0049]
Further, the present invention is not limited to the above-described embodiments, and various modes can be taken. For example, in the above-described embodiment, the disk is transferred by a plurality of drive pulleys, but the present invention is not limited to this, and other disk transfer devices may be applied.
[0050]
Further, in order for the drive pulley 44 to bring the disc 101 into sufficient pressure contact with the elastomer 24, the end of the guide wall 53 may be cut out and the disc 101 may be sandwiched between the drive pulley 44 and the elastomer 24.
[0051]
【The invention's effect】
As described above, according to the device of the present invention, since the high friction member is provided at a position facing the driving member that contacts the peripheral edge of the disk in order to transfer the disk, the disk and the disk holder are rotated when the disk is rotated by the driving member. Since it does not slip, the disk can be reliably pulled out from the disk holder.
