Turntable 61 is between front panel 2 and CD holding frame 11～15.Referring to Fig. 3, when CD 71 was supported by CD holding frame 11, turntable 61 was not overlapping with CD 71.But the CD 71 between front panel 2 and CD 71 is packed in the path.

Referring now to Figure 40,, the calcspar of circuit in the equipment 1 that draws among the figure.To processing, be to be undertaken by 91 pairs of data that read by optical sensor 66 of playback circuitry of a routine from the data of CD 71.Then result is exported from output terminal 92.One comprises the control circuit 93 control playback circuitry 91 of microprocessor etc. and controls cylindrical cam driving mechanism 82,83, belt wheel driving mechanism 84, driving-belt/guiding driving mechanism 85 and underframe driving mechanism 86 by timing described below.

Below with reference to the work of following this embodiment of description of drawings: the diagrammatic top view of Fig. 1 to Fig. 6 indication equipment 1; Fig. 7 represents the side view of CD holding frame transfer device 30, the vertical handover of this device control CD holding frame 11～15, and this illustrates the position P1～P11 of CD holding frame 11～15; Fig. 8～Figure 20 represents the rotation of CD holding frame transfer device 30; The side view of Figure 21～Figure 34 indication equipment 1 also illustrates CD and the motion of CD holding frame 11～15 in equipment 1.

Referring to Fig. 1, depositing the original state of CD, the driving-belt 45 of belt drive mechanism 40 and the guide wall 53 of guiding mechanism 50 move to the position of their spacing less than cd diameter.Referring to Fig. 7 and Fig. 8, in this original state, the engaging pin 18 on the flange 16 of the first CD holding frame 11 is positioned at the position P6 of the cam path 33 of first cylindrical cam 31.To be positioned the first CD holding frame 11 on the height identical like this with sealing 3 in the front panel 2.Engaging pin 18 on the flange 16 of second～the 5th CD holding frame 12～15 is positioned at the position P8～P11 of the cam path 34 of second cylindrical cam 32.

From then on state begins, and CD 71 is inserted sealing 3.Insertion force moves tape drive mechanism 40 in the direction of arrow D, and guiding mechanism 50 is moved same amount in the direction of arrow E, forms the state shown in Fig. 2 and Figure 21.This motion triggers belt wheel driving mechanism 84 is rotated counterclockwise belt drive mechanism 40 and drive pulley 43, and driving-belt 45 is changeed counterclockwise.Being bearing in CD 71 between driving-belt 45 and the guide wall 53 is turned clockwise and is transferred along the direction shown in the arrow F.Belt drive mechanism 40 and guiding mechanism 50 are moved to such an extent that leave a little each other, and CD 71 is moved to complete access arrangement 1.

Referring to Fig. 3, Fig. 9 and Figure 22, the turning handle CD 71 of driving-belt 45 moves into the first CD holding frame 11.Under this state, CD 71 is stably supported by the

CD supporting member

23,24 of CD holding frame 11 on about 180 degree scopes at its edge.For the CD 71 of after it is packed into, resetting, mobile at first in the direction of arrow D belt gear train of this driving-belt/guiding driving mechanism 40 and mobile guide mechanism 50 in the direction of arrow E.To remove belt drive mechanism 40 and guiding mechanism 50 from CD 71 like this.

Then, make underframe 63 turn over 45 degree from the retrieving position shown in Fig. 3 to the inverse position hour hands shown in Fig. 4 around axle 68.Underframe 63 is moved in the direction of arrow F.Underframe driving mechanism 86 is transplanted on the position shown in Fig. 5 and Figure 23 to underframe 63, so that the center pit 81 on the rotation center of turntable 61 and the CD 71 aligns.

From this position, by cylindrical cam driving mechanism 82 first cylindrical cam 31 is rotated counterclockwise 180 degree, make second cylindrical cam 32 keep motionless simultaneously.This will make CD holding frame 11 move on to position P7 from position P6, the distance of decline pitch L2.

Referring to Figure 10 and Figure 24, CD 71 is placed on the turntable 61.A unillustrated automatic clamping body is clamped in turntable 61 to CD 71 in each accompanying drawing.When CD holding frame 11 descended, other CD holding frames 12～15 kept motionless, because they are by keeping the second motionless cylindrical cam 32 to locate at this moment.

After CD 71 was clamped in turntable 61, underframe driving mechanism 86 was along the direction roll-out tray 63 of arrow G among Fig. 5.This will shift out CD 71 from CD holding frame 11, they are disengaged each other.This state is shown among Fig. 6, Figure 11 and Figure 25.So the moving handle CD 71 of underframe 63 from Fig. 5 to Fig. 6 shifts out from CD holding frame 11.Turntable 61, underframe 63 and underframe driving mechanism 86 are together as the CD withdrawing device.

Extract the position out from this CD, cylindrical cam driving mechanism 82 makes first cylindrical cam 31 clockwise rotate 360 degree separately.CD holding frame 11 reaches position P5 from the pitch L2 distance that the position P7 shown in Fig. 7 is raised twice.This state is shown in Figure 12 Figure 26.

Referring to Fig. 6, underframe driving mechanism 86 is roll-out tray 63 in the direction of arrow F.See that from above CD 71 is moved to same position as shown in Figure 5.Yet referring to Figure 13 and Figure 27, CD holding frame 11 moves vertically to the optical disc surface top apart from twice pitch L2 place.Therefore, if if rock on the surface of CD 71 or underframe 63 is suspended, even can prevent that also CD 71 from contacting with other members when then underframe 63 vertically rocks because of external vibration etc. when it rotates.

Referring to Fig. 1～Fig. 3, when underframe 63 is in retrieving position, turntable 61 be located in front panel 2 and each CD of being supported by CD holding frame 11～15 between.As mentioned above, the CD 71 of CD holding frame 11 pulled into the extraction position that is used to reset.Therefore, CD holding frame 11～15 must keep leaving with front panel 2, leaves predetermined distance between each CD holding frame and front panel 2.

Yet in this embodiment, it is for other reasons that underframe 63 must be configured in this space.When it is in retrieving position, turntable 61 the flat area that the handover from the CD 71 of Fig. 2 to Fig. 3 forms, be configured in not with CD holding frame 11～15 in the CD position overlapped on.So, do not need to reserve independent space for the retrieving position of turntable 61.This makes equipment 1 that less horizontal (the D-E direction among Fig. 1) and vertical (the F-G direction among Fig. 1) size can be arranged.

Below another Zhang Guangpan 72 programs are deposited in explanation in CD holding frame 12 after the playback of above-mentioned CD 71 has been finished.Referring to Fig. 5, Figure 13 and Figure 27, after the playback of CD 71 was finished, underframe drive unit 86 was along the direction roll-out tray 63 of arrow G among Fig. 5.

Referring to Fig. 6, Figure 12 and Figure 26, CD 71 is moved to this extraction position.Then, CD holding frame 11 is dropped to the position P7 shown in Figure 11 and Figure 27 from position P5.This makes cylindrical cam 31 be rotated counterclockwise 360 degree, make cylindrical cam 32 keep motionless the realization simultaneously by cylindrical cam driving mechanism 82.The rotation of cylindrical cam 31 aligns the height of CD holding frame 11 and CD 71.

Underframe driving mechanism 86 roll-out tray 63 in the direction of arrow F then.Referring to Fig. 5, Figure 10 and Figure 24, the edge of CD 71 inserts CD holding frame 11.Then, make cylindrical cam 31 dextrorotation turnbacks, CD holding frame 11 is moved on to position P6 from the position P7 shown in Fig. 7.Referring to Fig. 9 and Figure 23, CD 71 is lifted and clamping between CD 71 and the turntable 61 is disengaged.Underframe driving mechanism 86 moves on to position shown in Figure 4 to underframe 63 from replay position shown in Figure 5 and moves on to the retrieving position shown in Fig. 3 again, and it does not hinder the vertical movement of CD on this position.

Then, cylindrical cam driving mechanism 82 makes cylindrical cam 31 rotate counterclockwise 180 degree.Referring to Figure 10, CD holding frame 11 is at first brought back to position P7.Then, cylindrical cam driving mechanism 82,83 makes two

cylindrical cams

31 and 32 clockwise rotate 360 degree.This makes CD holding frame 11 move on to position P5 from position P7, CD holding frame 12 moves on to position P7 from position P8, CD holding frame 13 moves on to P8 from position P9, and CD holding frame 14 moves on to position P9 from position P10, and CD holding frame 15 moves on to position P10 (see figure 7) from position P11.

Referring to Figure 14, with cylindrical cam driving mechanism 82 rotating cylindrical cam 32 cylindrical cam 31 dextrorotation turnbacks and not.This makes CD holding frame 12 move on to position P6 (see figure 7) from position P7.Sealing 3 in the height of CD holding frame 12 and the front panel 2 aligns.This state is shown among Figure 15 and Figure 28.

Refer again to Fig. 1, the driving-belt 45 of belt drive mechanism 40 and the guide wall 53 of guiding mechanism 50 are moved to a spacing distance less than cd diameter.Then, referring to Figure 16 and Figure 29, CD 72 packed into by sealing 3 and inwardly go up CD 72 to be supported in the CD holding frame 12 in the same manner as described above.

Then, when wanting to reset CD 72, make underframe 63 move (Figure 30), and make first cylindrical cam 31 be rotated counterclockwise 180 degree and do not rotate second cylindrical cam 32.This make CD 72 be clamped to turntable 61 (Figure 17, Figure 31).Then, roll-out tray 63 so that with CD 72 from CD holding frame 12 extract out (Figure 18, Figure 32).First cylindrical cam, 31 dextrorotation three-sixth turns and do not rotate second cylindrical cam 32 so that CD holding frame 12 moves on to position P5 among Fig. 7 CD holding frame 11 move on to position P4 (Figure 19, Figure 33).Then, roll-out tray 63, the formation playback mode (Figure 20, Figure 34).

Because cylindrical cam 31 and opening in 32 minutes, can want this CD holding frame of the CD reset to move on to position P7 with being equipped with, it and replay position align there.Then, this CD holding frame can be moved on to position P5 and do not need to move another following CD holding frame of this CD holding frame or be contained in CD in this low level CD holding frame.So, reserve enough spaces can for the CD below that will reset.

In the replay device transfer mechanism of the above embodiment, turntable 61, optical sensor 66 etc. is configured on the underframe 63, and this underframe turns over 45 degree counterclockwise and moves then.This makes turntable 61 not move on to the optical disk data reproducing position with the overlapping retrieving position of CD from it.Yet, the invention is not restricted to this, the replay device transfer mechanism also can come mobile replay device with diverse ways.

In addition, in the above embodiment, the clip position coplane of the replay position of CD and CD.Yet, the invention is not restricted to this.Replay position also can be the position shown in Fig. 6, Figure 11 and Figure 25, and CD is extracted out from the CD holding frame on this position.

In above-described embodiment, CD holding frame transfer mechanism comprises

cylindrical cam

31,32, these cylindrical cams and 11～15 engagements of CD holding frame.Yet, the invention is not restricted to this, also can adopt other mechanisms that can realize similar operations.

In above-described embodiment, optical disk transfer mechanism comprises the driving-belt 45 with the engagement of the edge of CD.Yet, the invention is not restricted to this.For example, also can adopt the recording surface of supporting CD and a pair of live-roller of label surface.

In above-described embodiment, the CD supporting member comprises the CD holding frame, and this CD holding frame is at about 180 degree scope internal support CD edges.Yet, also can adopt other structure, for example lay a plate of CD thereon.In this occasion, if CD is installed on this plate, the recording surface that makes CD then makes this plate and plate thereunder descend after clamp operation towards this plate.The first and second CD supporting member transfer mechanisms must constitute like this, promptly during this step-down operation, keep off this plate that clamps CD thereon at the plate of laying above the plate.

During optical disk data reproducing, by the underframe driving mechanism CD and CD supporting member are moved away from each other, so that move the CD that is clamped in turntable.Yet, can certainly adopt the transfer device that this CD is sent to this equipment to come this CD moved on to and extract the position out.

As mentioned above, according to the present invention, replay device can be configured to, overlapping retrieving position is not positioned at and is used for extracting out within the space of a CD with being clamped in each CD in a plurality of CD supporting members to make its turntable, and this space is for shifting out CD setting from this CD supporting member.Therefore, do not need an independent space to be set for the retrieving position of replay device.

As mentioned above, replay operations is included in and moves each CD between deposit position in the CD holding frame and the replay position.Individual broadcast mode also is possible.Referring to Figure 34, in individual broadcast mode,, perhaps do not want to deposit the CD that will reset even all CD holding frames all take, then CD 72 can be transplanted directly on play position from sealing 3, clamped and broadcast on this position.When play finishing, CD 72 directly shifts out and time of not stopping in the CD holding frame through sealing 3.
