(F) Reproduction means A reproduction means 7 is placed near the back of the storage portion of discs 3 in order to make the record player as small as possible in depth. Since a holding means 14 in the reproduction means 7 is mounted on the reader lifter 10 as shown in Figure 2, the reader lifter 10 is first described. The reader lifter 10 is elaborated by forming a horizontal plate and vertical plates on both sides of the horizontal plate in body, and a cutout portion 10a having the shape of a circular arc is formed to allow the entry of a CD into the front side of the horizontal plate. A pair of bolts projecting horizontally 77 to raise and lower the reader lifter 10 are fixed on each of the vertical plates. The pair of bolts 77 are placed at the same height and are shorter than the pair of bolts 22b of said disc lifter 22. These bolts 77 are inserted through a pair of vertical slots 78 formed in each of the side plates Ib a lc of the frame 1 to project outwards from the frame 1. (F-1) Space-forming means As shown in Figure 2, as space-forming means 11 for forming a space above and below a CD selected by insertion between trays 2 stacked vertically one above the other, spacing cams 82 are provided. made of resin in such a way that they can slide freely in the longitudinal directions within the vertical plates of both sides of the reader lifter 10. That is, a guide groove 10a is formed in the upper front part of the vertical plate of the elevator reader 10 and a key-headed guide pin 82a inserted in the guide groove 10a is fixed on the gap 82, while a guide groove 82b is formed in the part bottom of the separation cam as shown in figure 3 and a key-headed guide pin 10b of figure 2 inserted in the guide groove 82b is held in an intermediate position in the longitudinal directions of the vertical plate. The separation cams 82 are inserted towards said tray 2 and stably carry the tray 2 four pins 2c and 2d on both sides of the tray 2 and forming a space above and below the tray 2 carrying a CD to be reproduced. The separation cams 82 are formed, each in a manner such that two plates differ in length in the longitudinal directions, said plates having each slit formed therein, are adhered therebetween, and are composed in such a way that the separation cams 82 slide on both sides of the tray 2 and thus make the front parts move on a pair of longer bolts 2c and the rear parts move on a pair of shorter bolts 2d. That is, they are composed in the following way. A pair of the first separation control portions 82cl, 82cl are formed in order to move a selected tray 2 carrying a selected CD and trays 2 above this selected tray 2, and a pair of second separation control portions 82c2 , 82c2 to move up only the trays 2 above the selected tray 2 are formed above the first separation control portions 82cl. And third separation control portions 82d, 82d to hold only the selected tray 2 are formed respectively between the first separation control portions 82cl and the second control portions of separation 82c2. An upper face 82f for holding the positions of the bolts 2c and 2d of the tray 2 on the selected tray 2 and a lower face 82h in a position control means for holding the positions of the bolts 2c and 2d of the tray 2 underneath the selected tray 2 and pressing the receiving portion 2g of the plate spring 2e are formed along the direction of movement of the separation cam 82. Since the pins 2c and 2d of the selected tray 2 and the tray 2 above the selected tray 2 are pushed up by the advance of the first separation control portion 82cl and the second separation control portion 82c2, are originally placed at a fixed value as? = 45 ° or similar, for example. In this case, however, the trays 2 are lifted by compressing the coil springs 24, and the higher the trays 2 are raised, the more the coil springs 24 are compressed and the applied load when the trays 2 are pushed up, becomes higher. In other words, the load is small in the initial compression stage of the coil springs 24. As shown in Fig. 21 (a), therefore, the upper portions of the first separation control portion 82cl and the second portion of separation control 82c2 take? 1 = 45 °, for example, while the lower parts take? 2 = 60 °, for example, and the Intermediate parts between the two are formed by arc-shaped faces. Next, the third separation control portions 82d, 82d will be described. The third separation control portions 82d, 82d are composed of upper stage penetration portions 82j, 82j, intermediate stage penetration portions 82k, 82k and lower stage penetration portions 82m, 82m. The upper stage penetration portions 82j, 82j are used to form space above and below a selected tray 2, the middle stage penetration portions 82k, 52 are used to lower the selected tray 2 and a selected CD and to place the CD selected on a turntable 97 of a lower arm 13, and the lower stage penetration portions 82m, 82m are used to lower again only the selected tray 2 and separate the selected tray 2 from the selected CD.

A gear train 103 is provided within the left side plate Ib of the frame 1 as shown in Figure 6. That is, the gear train 103 consists of gear 103a to 103h. On the other hand, a gear 104 is also fixed on the left end of said motor shaft 30. A plate 105 is provided in such a way that it can freely move in the vertical directions within the left side plate Ib. That is, a vertical guide groove 105a is formed in the upper part of the plate 105 and a guide pin 106 (see figure 28) inserted in the guide groove 105a is fixed on the left side plate Ib and a retaining ring it is clamped on the guide pin 106. Spring engaging portion 105b and 107 is provided respectively on the lower parts of the plate 105 and the bottom plate of the frame 1, and a return spring 108 for pulling down the plate 105 is provided between the two. A relief hole 105c, in which an axle 109 (fixed on the side plate Ib) of said gear 103h is inserted is formed in the plate 105, and the base end portion of a lever 110 is rotatably held on the shaft 109. A moving shaft 111 that penetrates the lever 110 is fixed to the front end portion of this lever 110, and a gear 102 engaged with the gear 103h is held rotatably on the movable shaft 111. A cam groove 105d is formed above the relief hole 105c in the plate 105, and a penetrating end portion of the moving shaft 111 is inserted in the cam groove 105d. That is, when the plate 105 is displaced upwards, the cam notch 105d is displaced upwards and the mobile axis 111 inserted in the cam notch 105d is displaced forwardly and thus the gear 112 clamped on the moving shaft 111 is engaged with a gear 104 of the motor shaft 3C. In order to move this plate 105 upwards, a middle portion of a lever 113 is rotatably supported on the inside of the left side plate Ib through a bolt 114, and one end of the lever 113 is connected rotatably with the lower portion of the plate 105 through a bolt 115. The other end of the lever 113 facing the front guide notch part of a pair of guide notches 25 of the left side plate Ib, said guide notch has a bolt 22b of the disk elevator 22 inserted therein. That is, when the disk elevator 22 reaches the lowest position to be in reproduction mode, the bolt 22b presses down the other end of the lever 113 to engage the gear 112 with the gear 104. The following will describe the highest gear 103rd of the gear train 103 and lower arm 13 of fastening means 14 meshed therebetween. As shown in Figure 2, a slide bar 116 consisting of a vertical portion elongated in the longitudinal directions and a horizontal portion forming in a body with a vertical portion in the rear portion of the vertical portion is provided as shown in FIG. Figure 2. A pair of guide notches 116a is formed near both ends of the vertical portion of the slide bar 116, and as shown in Figure 5, a pair of guide pins 117 inserted in the pair of notches. 116a are fixed on the inside of the left side plate Ib and have retaining rings attached thereto. In this way, a rack 116b is formed on the front lower side of the slide bar 116 that can freely slide in the longitudinal directions and said rack is engaged with said gear 103a, while the upper end of a hook bolt 116c which is projected downward is fixed on the end portion of the posterior horizontal portion. This latching bolt 116c is slidably engaged in a notch 13a of a horizontal portion formed as a body in the base end portion of said lower arm 13 and extends towards the height of the upper arm 12. This notch 13a is formed throughout a radial line passing through the axis of the sleeve 87 and is perpendicular to the sleeve 87. The turntable has two modes of operation including an insert / eject mode for inserting or ejecting a CD relative to the disc storage portion 3 and a reproduction mode for playing a CD, and the holding means 14 occupies the position B as shown in figure 30 in the aforementioned manner and occupies the position A as shown in figure 31 in the mentioned mode ultimately. The rotation operation of the clamping means 14 between the position B and the position A is effected through the rotational force supply means 17 as described above. Since it is necessary to precisely position a selected CD and the turntable 97 on the lower arm 13, however, a positioning means 118 of FIG. 10 is provided. The structure of the positioning means 118 is described below. As shown in Figures 9 and 10, the upper end of a positioning pin 119 projecting downwards is fixed on the lower arm 13 near the hollow shaft 86. On the other hand, the circular arc-shaped notch 10c is form in a reader elevator part 10 which corresponds to a range in which the positioning pin 119 is displaced as the media rotates. clamping 14, and the positioning pin 119 is slidably adjusted from the circular arc-shaped notch 10c. A spring engaging portion 10D projecting downwardly is formed in the reader lifter 10, and both ends of an articulated spring 120 are engaged by the spring engaging portion 110 and positioning pin 119. Whereas one position occupied by the positioning pin 119 when the clamping means 14 occupies the position B or A is position B or A, the position C which is a midpoint between B and A is a turning point in which the direction of movement of the positioning pin 119 and said spring engaging portion 10d are arranged in a position corresponding to the position c. (F-6) Regulating means The upper arm 12 of said clamping means 14 is pressed downwardly by said clamping spring 89, and a regulating means 18 for adjusting the time when the upper cradle must be lowered by the force of The pressure of this holding spring 89 is provided as shown in Figure 7. That is, it consists of the following. A cylindrical plate 124 is between said clamping means 14 and said separation cam 82 on the upper face of the reader lifter 10. This cylindrical plate 124 forms a partial cylinder which is a part of a cylinder having the sleeve 87 at its center and as shown in figures 32 and 33, the cylindrical plate 124 has a L-shaped guide groove 125 formed therein, said notch consisting of a long horizontal portion 125a in the circumferential direction and a vertical portion 125b long in the axial direction. On the other hand a guide pin 12a projecting outwards in the direction of the radius having the sleeve 87 at its center is fixed on the base end portion of the upper arm 12 and the guide pin 12a is inserted into the groove guide 125. The guide pin 12a is in the horizontal portion 125a when the holding means 14 occupies the position 3 which is a waiting position and while moving from the position B to a position that is found just on this side from the position A in figure X even if the upper arm 12 is pressed by a pressing force of the holding spring 89, it is not lowered and the holding means 14 is kept in the open state. On the other hand, since the guide pin 12a is located in the vertical portion 125b when the clamping means 14 arrives at the position B, the upper arm 12 is lowered by the pressing force of the clamping spring 89 and the clamping pin guide 12a results also in the descent of the lower end of the vertical portion 125 B. In order to make the securing means 14 do not effect immediately a clamping operation even when the clamping means 14 rotates towards the position A of figure 7 and the guide pin 12a rotates towards the vertical portion 125b of the guide notch 127 but to cause the clamping means 14 to effect a Finally, when a command is received, a first regulating means for temporarily regulating the downward movement of the guide bolt 12a and a second regulating means for removing the regulation and causing the holding means 14 to hold a CD are provided. selected when after the regulation said separation cam 82 moves downwards and then the selected CD and the selected patent leather 2 are lowered and placed in said turntable 97. That is, it is elaborated in the following manner. As shown in Figures 7 and 30, a support plate 126 is in parallel with the separation cam 82 between said cylindrical plate 124 and said separation plate 82 the upper face of said reader lifter 10. A middle portion of a restriction lever 127 is rotatably supported on the inside of the support plate 126 through a rotating shaft 129 as shown in FIG. 7, and an outwardly projecting bolt 127a is fixed on the front of the restriction lever 127, and the rear part of the restriction lever 127 is curved inward and toward the front to the vertical portion 125b of the guide groove 125. A spring 128 for pressing down the rear of the restriction lever 127 is provided as shown in Figure 30. On the other hand, the pin 127a of the front of the restriction lever 127 is loosely held in a cam groove 82r formed in the lower inner portion of the separation cam 82 as shown in FIG. 32. A relief portion is formed in the upper part on the rear side of this slot. cam 82r, and when the separation cam 82 moves forward and the pins 2c and 2d of the selected tray 2 penetrate the middle stage penetration portions 82k and 32k, a state is obtained in which the pin 127a can be released in the relief portion of the cam groove 82r and the restriction lever 127 is rotated by the spring 128 and the upper arm 12 is lowered by the pressing force of the retaining spring 89. (G) Extraction medium Extraction step 8 is provided in each of the right and left internal portions of the frame 1. Since these parts on both sides are almost equal in composition among them, only one of them will be described. As shown in FIGS. 1 and 19, the extraction lever 132 for removing a CD by means of its rotation is rotatably held on a fixed axis 133 which is projects downwards from the piace frame 1. The height of the extraction lever 132 is set at the same level as the height between said rollers 35 and 36. And both ends of the return spring 134 provided to surround the fixed axis 133 they engage with a spring engaging portion 132a formed in the extraction lever 132 and a spring engaging portion formed in the ceiling plate Ib. On the other hand, this mechanism is composed in such a way that the extraction lever 132 is rotated by a backward movement of the separation cam 82 opposite the space-forming action by a forward movement of the separation cam 82 as It has been described so far. That is, the composition is as follows. As shown in Figure 7, a plate 135 is provided in such a manner that it can freely slide back and forth over a fixed distance away from said support plate 126. In other words, a pair of guide notches 126a are formed in the support plate 126, while a guide pin 185a inserted in each guide slot 126a is fixed in the plate 135. The front end portion of the plate 135 is internally bent in such a way that it engages with a pressed portion 132b formed in a body with an extraction lever 132, and the end portion rear of the plate 135 is bent outward to project towards the rear of the separation cam 82. (H) Operating medium Finally, an operation means 9 is described. This operating means 9 raises and lowers the disk lifter 22 to allow a CD in a tray 2 in each stage to be inserted and ejected and further to open said opening / closing means 6 and operate the extraction means 8 in the insertion / ejection loop, and raise and lower the elevator 10 to select a CD to be played, the space forming tedium 11 operates and operates the regulating means 18 in a state in which the disk elevator 22 is held in the lowest position in the playback mode. As shown in figures 2 and 11, internal slides 139 (first control plates) and external slides 140 (second control plates) are provided outside the left and right side plates Ib and lc of the frame 1 such that they can slide freely back and forth. Since they are respectively symmetrical between them on the left and right sides, one side of them will be described. Guide grooves 139a and 140a are formed in the upper and lower plates of the internal and external sliders 139 and 140, respectively, and guide pins 158 and 159 fixed in the side plate are respectively inserted into both guide grooves 139a and 140a and have retaining rings fixed thereon. A pair of stepped grooves 141 (position control portion) for staggering a pair of bolts 77 of the reader lifter 10 in six steps, said bolts 77 projecting from the vertical grooves 78 and formed in the rear part of the groove. inner slide 139. A pair of stepped shoulders 142 (position control portion) for staggering a pair of bolts 22b of the disk lifter 20 into six steps, said bolts 22b projecting from the vertical slots 25, form in the front part of the internal slide 139, and bottom slots 143 to keep the disk lifter 22 in the lowest position and to make the reader elevator 10 only rise and fall in the reproduction mode are formed continuously with the stepped slits 142 and below them, respectively. On the other hand, only slits, in which a pair of bolts 22b which are the longer disc-lifter bolts 22b are inserted, are formed in the outer slide 140. That is, a pair of tetragonal-shaped slits 144 employed in the insertion / ejection mode for positioning the pair of bolts 22b in the stepped slots 142 and for raising and lowering them, a pair of slits in the form of a horizontal line 145 which are used in the reproduction mode for placing the bolts 22b in the bottom grooves 143 and holding them in the lowest position, and a pair of shift grooves inclined at 45 ° (mode change portion) to change the positions of the pair of bolts 22b between the pair of grooves stepwise 142 and the pair of bottom slots 143 by shifting up or down the bolts 22 ba through the tapered faces 146a and 146b through the sliding of the outer slider 140 in either direction are respectively formed continuously between they. Since the reproduction mode slits 145 are spliced together so as to be continuous between them if these slits 145 are formed in the same vertical position, the reproduction mode slits 145, the insertion / ejection mode slits 144. , the bottom grooves 143, the stepped grooves 142 and the bolts to be inserted therein are different in height from each other. The upper rear portion of the outer slide 140 is bent perpendicularly within to form a projection portion 140b. A relief cut portion 139b and a relief groove 147 are respectively formed in the backs of the used runner 139 and the side plate Ib such that this projection portion 140b can be displaced together with the outer runner 140.

In order to allow the separation cam 82 to slide together with the external slide 140 independently of the height position of the separation cam 82 moving up and down together with the reader elevator 10, a latching groove 32s in the vertical direction on the external face of the rear part of the separation cam 82 as shown in Fig. 2 and the projection portion 140b is slidably fitted in said latching slot 32s. And a latching portion 140c is formed by folding the front portion of the left outer slider 140 downwardly of the bottom plate of the frame 1. This latching portion 140c is pressed back said depressed portion 70c and opens the shutter 64 against the pressing force of the return spring 69 when the outer slide 140 slides backwards. Next, a driving mechanism for sliding said right and left internal slides 139 and said external slides 140 right and left at the same time synchronously between them will be described. As shown in FIGS. 2 and 2, two coupling shafts 148 and 149 are rotatably supported through the two pairs of supports below the back of the bottom plate of frame 1. Sprockets 150 and 151 are fixed , respectively, on both ends of the coupling shafts 148 and 149, and these pinions 150 and 151 are engaged, respectively, with racks 139c and 140d formed in the inner portions of the rear portions of the internal slides 139 and external slides 140. Gears 152 and 153 are they respectively fix on coupling shafts 148 and 149, and operation motors 154 and 155 are individually geared to these gears 152 and 153. That is, they are formed in the following manner. The operation motors 155 and 154 are mounted in the upper and lower positions within said support plate 126 positioned on the right side of the rear portion of the frame 1, and the driving shafts of these engines 155 and 154 are respectively engaged with the gears 152 and 153 through two sets of reduction gear devices 156 and 157 provided within the support plate 126. The operation of said turntable will now be described. (I) Entire composition of the operation The operation of the record player consists of three operations that include the insertion of a CD into the disk storage portion 3, the ejection of a CD from the disk storage portion 3 and the reproduction of a CD that selects and plays a CD among several CDs stored in the disk storage portion 3. (J) Inserting a CD In the case of inserting a CD into a disk storage portion 3, a given number is selected to a tray 2 (numbers from 1 to 6 are provided to the trays 2 in order of height from the top to the bottom) and press a number button not shown, for example, button "2" and then press an insert button not illustrated. The motor shaft of the operating meter 154 is transferred to the reduction gear means 156 and the coupling shaft 148 and the pair of internal slides 139 slide, and the action that the rotation of the motor shaft of the operation motor 155 is transferred to the medium of the reduction gear 157 and the coupling shaft 149 and the pair of external slides 140 slide are effected separately and independently from each other If a button is depressed when the pair of bolts 22b penetrates the pair of slots of insertion / ejection mode 144 of the external slide 140 and, for example, as shown in Figure 12, the pair of bolts 22b are in the mode change position in the insertion / ejection mode, the internal slide 139 it moves backwards and in this way the pair of bolts 22b each rises towards the second passage from the bottom of the stepped groove 142 as shown in Fig. 13 (a), and simultaneously with this, the disc lifter 22 is also raised and a CD in the second tray 2 from the top is adjusted to the height of the extraction lever 132. In this At this time, the reader lifter 10 also rises at the same time, but this action is an unnecessary action. When the internal slider 139 is moved further backwards, the reader lifter 10 is raised together with the bolts 22b and from the third to the sixth tray 2 reach the height of the extraction lever 132 in order. Then, when the outer slider 140 moves backward until the bolt 22b arrives from the position of Figure 13 (a) to an intermediate position in the forward and backward directions of the insertion / ejection mode slit 144, since the engaging portion 140c of the outer slide 140 presses back the pressed portion 70c illustrated in Figure 2 under the bottom plate l, the movement of the longitudinal slide plate 70 is transferred to the side slide plate 66 through the lever 72 and the side sliding plate 66 is moved to the left against the pulling force of the return spring 69, and the shutter 64 rises and the insertion opening in figure 17 (b). Since due to the above action the shutter 64 is open and the second tray 2 from the top already has the same height as the extraction lever 32 as described above, when attempting to insert a CD 171 between the upper and lower rollers 35 and 36 as shown in Fig. 17 (a), an unillustrated detector placed in the center on this side of the shutter 64 detects the CD 171 and the transfer motor 46 starts to rotate. Since the rotational force of the transfer motor 46 is transferred to the rollers 36 through the gears, the CD 171 is pulled between the roller 36 and the roller 35 pressed on the roller 36 by the spring 36 as shown in FIG. Figure 18 and the CD is inserted into the second tray 2 by rotating the rollers 35 and 36, but since the CD 171 is only inserted slightly apart from the rollers 35 and 36, it is pushed by several more millimeters by a couple of vertical rollers 57 pressed towards the center by the pressure springs 60. The CD 171 is held in the tray 2 by holding portions 2f of the pair of plate springs 2e. When the CD 171 leaves the rollers 35 and 36, a limit switch not illustrated operates and the transfer motor 46 stops rotating and at the same time the outer slide 140 moves forward and returns to the waiting position of the figure 13 (a), and consequently the pressed portion 70 which has been pressed backward is released and the shutter 64 is closed by the action of the return spring 69.

In the case in which the pair of bolts 22b occupies another height position (first or third to sixth from the bottom) of the stepped slots 142, also a CD can be introduced by the same operation as described above. (K) Ejection of a CD In the case of the ejection of a CD from the disk storage portion 3, for example, the button number "2" and the ejection motor are pressed. Accordingly, in the same manner as for the insertion, the bolt 22b is for example moved from the position of change in the insertion / ejection mode of Fig. 12 to the waiting position of Fig. 13 (a) and the CD in the second tray from the top is set at the height of the extraction lever 132. And in the same manner as described above, when the outer slide Í40 is moved backwards until the bolts 22b reach the position shown in FIG. Figure 13 (b), the shutter opens. The operation is essentially the same as the operation of inserting a CD. Then, when the outer slider 140 is further moved rearwardly until the bolts 22b reach the front portions of the insertion mode slits 144 as shown in Fig. 14, as shown in Fig. 19, the separation cam 82 engaged with the outer slide 140 through the projection portion 140b of the rear portion of the outer slide 140 moves backward and the rear part of the separation cam 82 presses the back of the plate 135 to move backwards. At this time, the front portion of the plate 135 presses back the depressed portion 132b of the extraction lever and the extraction lever 132 is rotated to eject each side of the second CD 171. Since the rollers 35 and 36 are already turned due to the fact that the transfer motor 46 is rotated at the same time when the ejection button is depressed, the ejected CD is inserted between the rollers 35 and 36 and ejected as shown in figure 20. In order to prevent the CD eject 171 falls, when a portion of the rear portion of the CU 171 is between the rollers 35 and 36, a switch of unknown limits detects this and the transfer control stops functioning. After this, the result is that the CD 171 is manually removed from between the rollers 35 and 36. When an unknown sensor detects that the CD 171 has been removed, the external pin 140 moves forward and the pins 22b return from the position of figure 14 to the waiting position of figure 13 (a). Therefore, since the backward force applied to from the separation cam 82 towards the plate 135 is removed, the extraction level 132 is activated by the elastic force of the return spring 134 and returns to the original position shown by a solid line in figure 19 (a), and Subsequently, the shutter 64 is closed, in the same way as after the insertion of a CD. In this case the pair of bolts 22b occupies another height position (first or third to sixth position from the bottom) of the stepped slots 142 also, a CD can be ejected by the same operation as described above. (L) Playing a CD In order to play a CD, a number button is pressed according to the CD number to be played, for example, button number "2" and the play button. After which, the inner slide 139 moves forward from the same state of Figure 13 to '< and in this way the bolts 22b descend to the lowest position of the insertion / ejection mode slot 144 to reach the mode change position and then the outer slide 140 moves forward. In this way, the bolts 22b are lowered by the pressure of the upper tapered faces 146b of the shift grooves 146 (see Figure 11 (c)) and are displaced in the bottom grooves 143 and at the same time these bolts 22b are displaced in the recesses of play mode 145 of the outer slider 140 and change in the playback mode as shown in Figure 15 (a). During this transfer, the pair of bolts 77 of the reader lifter 10 remain in the lowest positions of the stepped slots 141. The positions of the bolts 22b at this time are the shift positions in the mode of reproduction to the insertion mode / ejection, and when the outer slider 140 is made to move backward from this state, the bolts 22b are raised by pressing the lower tapered faces 146a of the shift slits 146 and can return to the shift position in said insertion mode / ejection as shown in Figure 12. The positions of the bolts 22b relative to the outer slide 140 appear in Figure 15 (a) and not only the mode change position but also the CD selection positions to change only the height of the reproduction elevator 10 and select a CD to be played. In other words, when only the inner slider 139 is made to move backward from the position of Figure 15 (a), the pair of bolts 22b seems to move relatively downward in the bottom slits 143 but in fact is maintain in the lowest positions of the vertical slots 25, and therefore the disk lifter 22 remains in the most reproducing position low but the other pair of bolts 77 hidden by the outer slide 140 so as not to be seen seems to rise relatively along the stepped grooves 141 but in fact rises along the vertical grooves 78 by steps. That is, when the pair of bolts 22b are located in the positions corresponding to the first 1 to 6 provided to the positions of the bottom grooves 143 by the fact that the inner slide 139 moves downward, the pair of bolts 77 it rises or descends to the heights corresponding to the numbers 1 to 6 provided in the vertical direction and a CC that corresponds to the relevant number is in a state in which it is reproduced. Figure 15 (a) is a state in which a CD of number 6 can be reproduced, and Figure 15 (b) is a state in which a CD number 1 can be reproduced. Since a CD of number 2 is selected here in accordance with that described above, the pair of pins 77 rises to the second position from the top as shown in Figure 16 (a). As a result of the above operation, a CD to be played enters a state in which it can be played and the next operation is the same also in the case in which a CD of any number is selected, and is made by the movement of the external slide 140 and the drive of the transfer motor 46. The action after the waiting state of Figure 16 (a) wherein a number 2 CD to be reproduced is selected in accordance with what is described below. A state where the pin 22b occupies the position D in the outer slider 140 of Figure 16 (b), that is, a state of Figure 16 (a) is the waiting state and at this time the separation cam 82 is in the position of Figure 22, and when the outer slide 140 moves forward and the bolt 22b arrives at the position E as the first stage, the separation cam 82 moves forward and the lower front end of the rear portion of the separation cam 82 penetrates between the bolts 2d of the second and third trays 2 from the top (as for the bolts 2c also, the lower front end of the forward position of the separation cam 82 enters between the bolts 2c and the next operation is carried out in the same way as in the case of the bolts 2d), and then, when the bolt 22b reaches the position F as the second stage, the bolt 2d of the second tray 2 starts from the top slides in the first separation control portion 82cl and assembles the upper stage penetration portion 82j and the upper front end of the separation cam 82 penetrates between the bolts 2d of the first and second trays 2 from the top to reach the state of Figure 23, and then, when the pin 22b reaches position 3 as a third stage, the pin 2d of the first tray 2 from the top slides in the second separation control portion 82c2 and assembles the upper face 82f of the separation cam 82. Due to this, when the bolt 22b reaches the position G in the third stage a space is formed above and below the second tray 2 selected from the top as shown in Figure 24. When an illustrated nc sensor detects that the bolt 22b has reached position G of Figure 16 (b), the transfer motor 46 starts to rotate. Since a state in which the pair of bolts 22b enters the bottom grooves 143 and the lever 113 of the rotary force supply means 17 is depressed downwards, it is obtained when the operation mode changes to the reproduction mode as described above, a state has already been reached where the lever 113 is rotated counterclockwise around the bolt 114 from the state of Figure 28 (a) and the plate 105 is raised and the lever 110 is rotated clockwise about the shaft 109 and the gear 112 is also engaged with the gear 104 engaged with the gear 103h as shown in Figure 28 (b).

Accordingly, the rotation of the transfer motor 46 is transferred to the slide bar 116 having a rack 116b through the motor shaft 30 and the gear train 103, and the slide bar 116 is moved rearwardly as shown in FIG. Figure 29. At this time, since the latching bolt 116c of the lower rear portion of the slide bar 116 is slidably fitted in a notch 13a, the fastening means 14 is rotated forward and when the bolt positioning 119 of Figure 10 (a) passes to a position c which is the inflection point, the pressing force of the articulated spring 120 acts in the opposite direction and the positioning pin 119 is rotated towards a position a as shown in Figure 10 (b), and as shown in Figure 24, the upper arm 12 and the mandrel plate 99, and the lower arm 13 and the turntable 97 are respectively above and below a CD 171 to be reproduced. Seeing this with plan views, the state changes from Figure 30 to Figure 31. The transfer motor 46 stops rotating due to a limit switch not shown to detect the rotation of the clamping means 14. When the external slide 140 it moves forward until the bolt 22b reaches the position H of Figure 16 (b) as a fourth stage the bolt 2d of the selected tray 2 descends into the penetration portion of intermediate stage 82k and in this way the selected tray 2 and the selected CD lower and the selected CD is placed on the turntable 97 as shown in Figure 25. And almost at the same time, the outer slide 140 and the cam The separation 82 moves forward, and thus the regulating means 18 operates and the upper arm 12 of the clamping means 14 is pushed downwards by the action of the clamping spring 89 and the CD to be reproduced is maintained between the turntable 97 and mandrel plate 99. That is, a detailed description of the clamping operation is presented below. When the bolt 22b is in the position G and the clamping means 14 occupies the standby position B, the guide bolt 12a is located in the horizontal portion 125a of the guide groove 125 as shown in Figure 32, and when the holding means 14 occupies the reproduction position A, the guide bolt 12a moves towards the vertical portion 125b of the guide groove 125 as shown in figure 33 a), but since the bolt 127a can not be As the relief portion of the cam groove 82r of the separation cam 82 is relieved, the guide bolt 12a can not descend due to the hindrance of the rear face of the restriction lever 12. Then, when the bolt 22b is displaced towards the position H, since the separation cam 82 also moves forward, the pin 127a can be relieved towards the portion of relief of the cam groove 82r as shown in Fig. 33 (b) and the bolt 127a of the restriction lever 127 depressed by the spring 128 moves up towards the relief portion of the cam groove 82r of the cam of separation 82 and the back of the restriction lever 127 descends. Because of this, as shown in Fig. 34, the upper arm 12 pressed by the holding spring 89 descends and the selected CD 171 is maintained as described above. The center of rotation of the clamping means 14 is placed with high precision on the bottom plate by the insertion of the post 92 placed on the bottom plate in the hollow shaft 86 which is the center of rotation of the clamping means 14, and the positioning bolt 119 is maintained in a state in which it is pressed against the reader lifter 10 by the articulated spring 120, and consequently the turntable 97 and the mandrel plate 99 are accurately positioned in a circumferential location. On the other hand, since the guide post 23 for guiding a tray 2 carrying a CD 171 is also on the bottom plate in the same manner as the post 92, the CD 171 is also placed precisely on the plate you. Accordingly, the center of the CD 171 to be reproduced, the center of the turntable 97 and the center of the mandrel plate 99 accurately match each other, and the CD 171 is clamped firmly. As the fifth final stage, when the outer slide 140 moves forward until the bolt 22b reaches the position I of Figure 16 (b), the bolt 2d of the selected tray 2 descends into the lower stage penetration portion. 82m as shown in Fig. 21 (a) and the selected tray that has been in contact with the CD selected so far drops as shown in Fig. 26 to leave the selected CD 171 and at the time, the receiving portion 2h of the plate spring 2e which has pressed the selected CD 171 is pushed up the lower face of the upper stage penetration portion 82 of the rear portion of the separation cam 82 and consequently the selected CD is released as shown in Figure 27. Since at this time the trays 2 below the selected tray 2 are pressed by the lower side 82h of the separation cam 82 and the trays 2 on top of the selection tray. 2 are pressed downwardly by the coil spring 24, the trays 2 do not vibrate despite the vibrations caused by the vehicle. Then, the selected CD is held by the clamping means 14 in such a way that the CD is reproduced in a state in which the clamping means 14 is maintained in position A as shown in Figure 31. When the motor of shaft 96 rotates first, the CD rotates through the turntable 97. Then, when a motor 165 for scanning the reading unit 16 rotates, its rotation is transferred to the threaded shaft 164 and the optical reader 162 moves along the length of the threaded shaft 164 from the inner part to the outer part in a radial direction of the CD, and the CD is played. After CD playback, when the threaded shaft 164 rotates in reverse and the optical reader 162 returns to its original position, the scanning motor 165 stops rotating and the shaft motor 96 also stops rotating. After this, in accordance with a procedure reverse to the aforementioned procedure, the outer slide 140 moves backwards and the separation cam 82 also moves backwards. As shown in Fig. 21 'b), when bolt 127a returns from position H to position G, bolt 127a of restriction lever 127 that has been in the position of Fig. 33 (b) moves away from the relief portion of the separation cam moves downward as shown in figure 33 (a) and the rear part of the restriction lever 127 s moves upwards. Due to this, the bolt 12a projecting outwards from the fastening means 14 is pushed upwards along the length of the vertical position 125b of the guide groove 125 and the holding means 14 reaches a state in which it can be rotated. After this, an unillustrated sensor detects that the guide pin 12a is moved upwards, the transfer motor 46 is activated in the reverse direction to the above mentioned direction and the clamping means 14 is activated towards the rear side. And when the positioning bolt 119 which has occupied the position A of figure 10 (b) passes the position C which is the inflection point, the pressing force of the articulated spring 120 acts in the opposite direction and rotates the bolt of positioning 119 towards position B as shown in figure 10 'a) and holding means 14 returns to position B which is the waiting position. Due to a limit switch not shown to detect rotation of the clamping means 14, the transfer motor 46 stops rotating. Since, if the clamping means 14 is pressed downwards by the articulated spring 120 even in the waiting position, it is not influenced by the vibration of the vehicle. After this, when the slide 140 moves backwards and the bolt 22b returns to the position of separates D of figure 16 (b), the separation cam 82 also moves backwards and all the trays of the first to the third 2 they go down and return to the state of figure 22 where the six Trays 2 are not separated. In the case of the reproduction of a CD other than the second CD from the top, the inner slide 139 moves forward or backward from the state of FIG. 16 (a) and the pin 22b moves relatively to one of the positions 1, 3, 4, 5 and 6 given to the internal slide 139 in the figure, and then the outer slide 140 is slid and the positions D to I in the external slide 140 of FIG. 16 (b) they adjust to the bolt 22b in order, and in this way the same operation as described above can be repeated. As described above, the repetitive operations of engraving, reproduction and ejection can be effected by means of only the first and second control plates and means of formation of spaces and thus the composition of the apparatus can be greatly simplified. And since the first second control plates are moved in a direction perpendicular to the stacking direction of the disc carrying means in the disk storage portion, it is sufficient that the thickness of the apparatus is approximately the thickness necessary for the means which carry discs move in the stacking direction and consequently the whole apparatus can be manufactured in a stationary manner. And by making the slit change (mode change portion) 146 is longer, it is possible to make the lowest position of the insertion / ejection mode slot 144 higher and cause the disk elevator 22 to remain in a higher position when the pin 22b arrives to the position of figure 12. For this reason, it is possible to make an insertion / ejection opening 4 plus can for a CD. And the aforementioned modality to be considered that the number of trays that form the disk storage portion is six, but it can be a larger number or a number less than six. And further, this embodiment uses trays illustrated in Figures 3 and 4, but can employ a pair of carrier pieces obtained by trimming portions illustrated by the lines of a long stripe alternating with two short stripes in the figure, leaving only both portions laterals carrying the outer circumferential portion of a CD and removing the middle part of the aluminum plate 2a. INDUSTRIAL EXPLOITATION The above-mentioned embodiment is a turntable for reproducing a sound to which a disc recording and / or reproducing apparatus of the present invention is applied, but the present invention is not limited to this and can be applied to an apparatus for recording an sound, a device for recording and reproducing a sound, or a device for record and / or play not only a sound but also an image. And the above-mentioned embodiment has been described taking into account that the direction in which the trays are stacked one on top of the other is the vertical direction, but the stacking direction of the trays one on the other can be the horizontal direction. This method uses a disk 12 cm in size, but can also be applied to a disk that has another size, such as 8 cm or similar.
