Here, in order to facilitate understanding of the automatic playback device A of the present invention, a cartridge D containing a disc and a playback device C (CI,
The schematic configuration of C2) will be explained.

As schematically shown in FIG. 2, the cartridge D consists of a rectangular cartridge main body 2 (hereinafter referred to as a sleeve) and a lid body 3 detachably connected to the main body 2.
A disk 10 such as a video disk is housed in the flat space. That is, the sleeve 2 has a pair of half-holes 2a,
2a are put together top and bottom with their lids together, and the insertion direction side (indicated by arrow Z1) is set as an opening 4, and the remaining three sides are closed to form a rectangular shape, and the lid body 3 is connected to the opening 4 of this sleeve 2. The lid is removably connected to open and close the lid.

The lid body 3 is constructed by inserting the main body part 5 (its thickness is approximately equal to the distance between the openings 4) between the upper plate 6 and the lower plate 7 of the sleeve 2, and inserting a pair of engaging parts protruding from both sides. Convex portions 9 of arms 8, 8,
9 elastically engages in the recesses 11.11 formed on both sides of the sleeve 2, and the wide flange 12 on the front abuts against the opening side ends of the upper and lower plates 6, 7, and moves in the directions of arrows Zl and Z2. It covers the opening 4 and is coupled to the sleeve 2, with movement of the sleeve 2 being restricted. In addition, a pair of overpass portions 3a are formed in the center of the lid 3, into which a disk clamp mechanism, which will be described later, enters.

On the other hand, as schematically shown in FIG. 3, the playback device C that plays back the disc 10 in the cartridge D is configured to expand the sleeve 2 provided at the introduction port 14 of the casing 13 into which the cartridge D is introduced. Opening mechanism 15, disk 10

It is roughly composed of 7. Note that 18 is a guide portion that is formed protruding from the introduction port 14 and is used to introduce the cartridge D, which has a tapered opening portion 18a.

The sleeve expanding mechanism 15 is configured as shown in Utility Model Application No. 16206/1987, which was previously proposed by the applicant of the present invention, and the sleeve expanding mechanism 15 is configured as shown in Utility Model Application No. 16206/1987, for example, when the sleeve 2 is inserted into and withdrawn from the reproducing device C. It moves back and forth between the return position on the side and the innermost part of the device.

When playing a disc, the disc 10 is mounted on a turntable 19 within the playback device C. This disk mounting operation is automatically performed by the reciprocating operation of the cartridge insertion/removal means J, which will be described later in the carrier mechanism F.

That is, the cartridge insertion/removal means J of the carrier mechanism F inserts the sleeve 2 from the guide portion 18 through the introduction port 14 to the innermost part of the apparatus, and then pulls it out. Further, when the cartridge D is inserted, the insertion position of the cartridge D is regulated by the action of the tapered portion 18a formed at the opening of the guide portion 18.

Therefore, the sleeve 2 has its opening 4 as shown in FIG.
The sleeve is inserted in the Z1 direction along the guide rails 21a, 21b with the left and right ends supported by the sliders 20a, 20b in an expanded state by the sleeve IF11 mechanism 15.

When the cartridge D is inserted to the innermost part of the playback device C, the lid 3 is stopped by the lid latching mechanism 17.17,
The outer group guard of the disk 10 is connected to the clamp mechanism 16.
, and only the sleeve 2 is pulled out in the direction of arrow Z2. Note that this lid body 3 is connected to a pair of lid latching mechanisms 17.
When the lid body 3 is latched by the lid member 17, an elastic return force is accumulated in the lid body 3 by an elastic means (not shown).

At the stage when the sleeve 2 is pulled out from the reproduction device C,
The lid body 3 is hung and held at the back of the device as shown by the two-dot chain line, and the disk 10 has its outer group guard clamped to the clamp mechanism 16, and its center hole 10a is positioned above the turntable 19. Supported. Thereafter, in response to a play signal, the clamp mechanism 16 releases the clamp, the support ring 22 descends, and the disk 10 is placed on the turntable 19 and is mounted by being clamped at the center hole 10a.

Here, the disc 10 is moved to the turntable 1 by a motor.
The pickup means 23 rotates integrally with the recording medium 9 and moves in the direction of the arrow P.

When the reproduction mode ends, the disc 10 stops rotating, and contrary to the above case, the support ring 22 rises, the clamp mechanism 16 operates, and the disc 10 is supported at a position above the turntable 19. In this state, when the empty sleeve 2 is inserted into the playback device C using the cartridge insertion/removal means J and pulled out in the same way as the above-mentioned loading operation, the disc 10 is placed in front of the loading position of the disc 10 together with the lid 3. Due to the elastic force accumulated above, the sleeve 2
It is stored as if rushing inside. This causes disk 10
is collected into cartridge D and taken out from playback device C.

Next, the specific structure of the disk storage rack B (B1, B2) will be explained with reference to FIGS. 4 to 6.

As shown in the external perspective view of FIG. 4, the disc storage rack B is composed of a box body 25 with an opening 24 on the side, and inside the box body 25, the cartridge D shown in FIG. The upper and lower plates 26a and 26b are provided with concave grooves n+, n2, .
31 are formed respectively.

Each concave groove nl, n2...n 31 of the lower plate 26b is the fifth groove.
As shown in the enlarged view, the width of the central portion corresponds approximately to the thickness of the cartridge D, and the distance from the upper plate 26a is approximately 1/3 of the width from the opening 24 to the inner part. A tapered surface 27 is formed so as to become gradually larger toward the opening 24 side, and these concave grooves nl, n2...n 31
Tapered surfaces 28 are formed on both side surfaces of the plurality of partition walls p1, .

In this way, the openings 24 of the concave grooves nl, n2...n 31
By forming the sides so that the vertical and horizontal dimensions become larger sequentially from the center, when the cartridge insertion/removal means J described later inserts/removes the cartridge D into/from the disk storage rack B, the cartridge D Even if the rack is slightly tilted, the operation can be carried out smoothly by both tapered surfaces 27 and 28 of the rack.

Further, in the vicinity of the innermost part of the box body 25 of the partition walls p1...pn, the width of the concave grooves nl, n2...n 31 is larger than the width of the central part (width corresponding to the thickness of the cartridge D). Step portions p1a, p2a, etc. are formed respectively, and a plurality of leaf springs 29 having a shape as shown in FIG. Each one is locked. That is, the leaf spring 29 is bent into a U-shape with a pair of elastic arms 29a, 29a formed on both sides of the front piece 29b, and the front side is bent so that the elastic arms 298, 29a face into the adjacent concave groove. Piece 29b and locking piece 2 protruding from this piece
9G is positioned on the opening 24 side and is locked to the partition walls p1...pn as shown in FIGS. 4 and 5. Therefore, the cartridge D is stored in a vertical position with the lid body 3 as the leading end in the disc storage rack B as shown in FIG. are concave grooves nl,...n
The movement in the width direction is restricted in the central part of n, and the leaf spring 2 installed there
Due to the expanding action of the elastic arms 29a, 29a, the elastic arms 29a, 29a are elastically clamped from both sides, and movement in the front and back direction is restricted.

Note that the inside of the disc storage rack B has a concave groove nl.
, n2...n30, 30 cartridges D containing disks are sequentially inserted, and the last concave groove n3t is inserted.
The space is left empty so that an empty sleeve 2 can be inserted. Therefore, the cartridge D loaded into the device A of the present invention has two upper and lower parts.
In total, the disc storage racks B+ and B2 can store 60 discs.

In addition, in Fig. 4, 30 is a shutter mechanism, which is
It has a function of opening and closing the opening 24 side of the 31st concave groove n 31 of the body 25.

That is, the shutter mechanism 30 is as shown in external perspective views in FIGS. 7(A) and 7(B), with FIG. 7(A) showing the closed state and FIG. 7(B) showing the open state. ing.

In FIG. 7, a pair of upper and lower shafts 32a and 32b embedded in the base plate 31 of the shutter mechanism 30 are biased with rotational force in the counterclockwise direction by coil springs 33 and 33 fitted into the shafts. A pair of arms 34a.

34b is pivotally supported, and also a pair of arms 34a.

A plate-shaped shutter 35 is pivotally supported at one end of 34b. This shutter mechanism 30 is mounted on the opening 24 side of the box body 25 so that the shutter 35 is positioned so as to close the concave groove n31.

Here, when the disc storage rack B with the shutter mechanism 30 attached is taken out from the automatic playback device @A, the shutter 35 is moved by the counterclockwise rotational force of the pair of arms 34a and 34b as shown in FIG. >, the opening 24 side of the concave groove n31 for storing empty cases is always closed, and when the disc storage rack B is inserted into the automatic playback device mA, the protrusion 36 of the device is closed. When the lower arm 34b is locked and rotated clockwise about the shaft 33, the shutter 35 is opened as shown in FIG. 7(8).
The substrate section 31 is moved in parallel to the right in the figure along the guide plates 31a and 31b to open the opening 24 side of the concave groove n31. Therefore, each disk storage rack 81. B2
When taking out the cartridge from the automatic playback device A and storing the cartridge D, there should be 3 holes in each concave groove n+-nao.
Although 0 cartridges D can be stored, the 31st concave groove n 31 is the shutter 35 of the shutter mechanism 30.
Since the inlet portion is closed by the inlet, there is no possibility that the cartridge D will be accidentally stored there.

Further, as shown in FIG. 8, the disk storage rack B has a concave portion 37 formed at a predetermined position on the bottom.

On the other hand, a mounting member 38 (
(shown in FIG. 1) is provided between the support 42 and the disc storage rack B at a corresponding position to engage with the recess 37 when the disc storage rack B is placed in the normal position thereon. A locking mechanism 41 is disposed in which a protruding shaft 40 that is elastically moved up and down by a stretched coil spring 43a is projected.

Reference numeral 45 denotes a locking piece fitted into the shaft 44 of the support body 42 and the protrusion shaft 40, which is applied with a lifting force by the coil spring 43b fitted into the shaft 44 and the coil spring 43a of the protrusion shaft 40. Forced.

Therefore, when trying to replace a plurality of cartridges D in the disc storage rack B (B+, B2) stored in the automatic playback device 1A as shown in FIG. After pulling it out and taking it out as shown in the fourth figure, and storing the cartridge D in each of the 30 recesses 11n+ to n30 excluding the recessed groove n31, this disk storage rack B is placed on the mounting member 38. Then, the automatic regeneration device A is turned on again as shown in the first diagram.
At this time, as shown in FIG. 8(A), when the concave portion 37 of the disk storage rack B and the protruding shaft 40 of the locking mechanism 41 are in the correct mounting position, Since the protruding end of the protruding shaft 40 enters the recessed part 37, the one end 45a of the raised locking piece 45 does not correspond to the protruding part 46 of the housing 1, so that the disk storage rack B is movable into the apparatus together with the mounting member 38, and is reliably loaded.

When the disk storage rank B reaches the final rest position together with the mounting member 38 by loading the disk storage rack B into the equipment, the shutter mechanism 30 shown in FIG.
As shown in FIG. 7(8), one end of the lower arm 34b is locked to the protrusion 36 of the housing 1, so the shutter 35
can be moved in parallel from the concave groove n31 by clockwise rotation of the pair of arms 34a and 34b, thereby opening the 31st concave groove n31.

Here, as shown in FIG. 8(B), if the disk storage rack B is not placed in the normal placement position of the placement member 38, the protrusion shaft 40 of the locking mechanism 41 will be inserted into the disk as shown in the figure. Since it does not correspond to the concave portion 37 of the storage rack B, it is pressed against the bottom surface of the rack B and descends against the elastic force of the coil springs 43a and 43b. This protruding shaft 40
As the locking piece 45 lowers, the locking piece 45 also lowers and its one end 4
5a corresponds to the protrusion 46 of the housing 1, and prevents the placing member 38 on which the rack B is placed from entering the apparatus, thereby stopping the operation of the apparatus and protecting it. .

Next, the drive mechanism E of the device A of the present invention will be explained for each drive unit.

As shown in FIG. 1, the drive mechanism E includes a carrier mechanism F having a cartridge insertion/removal means J as described above, and an elevating mechanism G.
and a selection drive mechanism H.

As shown in FIG. 9, the carrier mechanism F and the selection drive mechanism H, which constitute a part of the main parts of the drive section, are mounted on a rectangular unit base 48 formed by a horizontal bridge 48a and a vertical bridge 48b. It is set in. As shown in FIG. 1, the unit base 48 equipped with each drive unit is connected to one end of a timing belt 68 driven by output pulleys 67, 67 of a lifting mechanism G having a built-in motor. Storage racks 81, 82 and playback device C
1, a pair of guide shafts 47a, 4 facing the operating side of C2
7b has a pair of upper and lower bearing portions 49a.

49b is supported and moves up and down on this axis in the Yl and Y2 directions. In addition, 69 is the timing belt 68
It is a weight suspended from the other end.

Also, both vertical bridges 48b of the unit base 48.

A base portion 52 that rotatably supports the carrier mechanism F is attached to a pair of shafts 50 and 50 extending between the shafts 50 and 48b so as to be slidable in the X1 and X2 directions by a bearing portion 51.

Further, a rotation shaft 59 of the carrier mechanism F is attached to the base portion 52.
is supported. Therefore, the carrier base 54, which will be described later and which forms the casing of the carrier mechanism F, is a unit base 4.
It is mounted substantially perpendicularly to 8 and in a rotatable state. Also shown in the figure is a rotation drive unit that rotates the carrier mechanism F, which is also shown in FIG. 10.

Reference numeral 53 denotes a motor that rotates the carrier mechanism F that is installed in the base portion 52 that supports the carrier mechanism F, and a pulley 57 that has a pattern disk 57a for a sensor on its output shaft is connected to the carrier base. It is driven by a belt via a worm gear 56a that meshes with a worm wheel 55 that is integrated with a rotating shaft 59 provided on a base 54a of the worm gear 54, and a pulley 56 provided on the shaft of this worm gear 56a.

In addition, the motor 53 rotates the carrier base 54 by 9 rotations at 40 rotations.
The gear ratio of the reduction mechanism such as the worm gear 56a and the wormhole 55 is appropriately set so as to rotate the pattern disk 57 by 0''.
This is a sensor that detects a pattern formed on a.

The selection drive mechanism H is provided on the unit base 48, as shown in FIG. 63, and the worm gear 63 drives the worm wheel 64.
5 to rotationally drive a pair of timing gears 66, 66 supported on the horizontal frame 148a. Note that 70 is a belt installed over the timing gears 66 and 66, and the base portion 52 that rotatably supports the carrier base 54 of the carrier mechanism F is fixed to this belt.

A sensor assembly 74 as shown in FIG. 10 is fixed to the upper end of the base portion 52. A sensor is provided at a position facing the address detection pattern 73 formed on the side surface of 48a. Therefore, by the rotation of the address motor 60 in a predetermined direction, the sensor assembly 74 of the base portion 52 supporting the carrier mechanism F is activated in both XI and X2 directions while reading the formed address detection pattern 73, as will be described later. Run to.

The specific structure of the sensor assembly 74 is as shown in the exploded perspective view of FIG. 12. That is, 77 is the flat plate part 7
It is a supporting frame formed by bending a pair of leg parts 77b, 77b protruding from 7a into a substantially U-shape, and both leg parts 77b, 77
A running member 76 having rollers 82.84 is vertically movably supported on a shaft 79.80 mounted on the bll, and a sensor 85 is mounted on mounting pieces 76a and 76b on the lower surface of the running member 76.
A sensor plate 75 having a sensor plate 75 is fixed by a fixing means such as a screw.

81 is a coil spring inserted between the support frame 77 and the running member 76, and the elastic force of this spring causes the running member 7 to move.
6 elastically moves up and down on shafts 79 and 80 within the support frame 77.

Further, 78 is an adjustment screw loaded between the legs 77b, 77b of the support frame 77 and passing through the running member 76;
By rotating and adjusting this, the position of the running member 76 in the left and right direction with respect to the running direction is adjusted, and the supporting frame 77 is also adjusted by the elastic force of the leaf spring 83 inserted between the two.
Movement in the left and right directions is restricted.

Therefore, the sensor assembly 74 having the above-mentioned configuration has the sensor 85 attached to the bottom of the sensor assembly 74 connected to the address detection pattern 73.
When the sensor 85 of the traveling member 76 is not attached to the upper end of the base portion 52 in a state where the sensor 85 of the traveling member 76 faces the sensor 85, each track of the address detection pattern 73 and the sensor 85 of the traveling member 76 can be accurately positioned by appropriately adjusting the adjusting screw 78. Therefore, the detection accuracy of the cartridge D is improved.

Further, the sensor assembly 74 is indicated by X+ in FIG.

When traveling in the ×2 direction, even if an error occurs in the assembly accuracy of the mechanism and the sensor 85 separates from the surface of the pattern 73, making it difficult to detect the pattern, the traveling member 76 remains between the support body 77 and the sensor 85. Due to the action of the coil springs 81 and 81 inserted in the coil springs 81 and 81, it moves up and down elastically to absorb errors.
Reliable pattern detection can be performed.

Here, the disk insertion/removal means J and the carrier mechanism F

FIG. 13 shows a specific configuration of the guide groove 88 formed in the arm portion 54b, which is a side view seen from the direction of arrow W in FIG. The guide groove 88 is slightly larger than the length in the insertion direction of the cartridge D shown in FIG.
The tip portion 88G on the guide plate 71 side is a tapered portion so that the front opening side becomes wider sequentially, and the central portion 88b continuous with this taper portion has a neck portion 88d that approximately corresponds to the thickness of the cartridge D as a fulcrum. It has a wide range of settings so that it can be rotated as follows.

Therefore, the cartridge insertion/removal means J operates as described below.
With the cartridge D clamped, the carrier base 54 rotates 90 around the shaft 59 supported by the base portion 52.
When rotating and loading a disc into a playback device C as shown in FIG. The rear end portion of the cartridge D rotates within the center portion 88b with respect to the neck portion 88d so that the end portion is regulated by the guide portion 18 of the reproduction device C shown in FIG. 3 and loaded into the device. In this way, during the insertion process of the cartridge D, the positional deviation with respect to the playback device C may occur in the guide groove 8.

In other words, when the clamper 96 is clamping the cartridge D as shown in FIG. 14 (A>), the cartridge D is not subjected to any protruding force by the coil spring 108 and is in a stable clamped state. , when the cartridge is loaded, the rotation of the motor 101 causes the clamper 96 to rotate as shown by the solid line in FIG. 11, and in the open state as shown in FIG. 14(B), the cam 9 of the cam gear 99
9a releases the pressing force of the flange 112, and as the punch 112 moves in the z1 direction, the pusher bottle 106
, 106 are moved in the same <Z+ force direction. Therefore,
Cartridge D has a pair of extrusion bottles 106 at its rear end.
．． Since the cartridge D moves in the Z+ force direction while being elastically pressed by the reproducing device C
It is inserted easily and elastically into the inside. In this way, the operation of the clamper 96 and the extrusion bin 106 can be operated by the single motor 101, so the mechanism is simplified and the clamping operation becomes reliable.

Here, the specific operations of the information recording medium automatic selection and reproduction apparatus of the present invention configured as described above will be sequentially summarized and explained.

(1)) Cartridges D as shown in FIG. 2 are placed in 30 concave grooves n1 to n30 in the disc storage rack B configured as shown in FIG.
Store the sheets. When this disk storage rack B is taken out from the apparatus, as described above, the shutter 35 of the shutter mechanism 30 closes the concave groove n3t as shown in FIG. 7(A).

Here, the disc storage racks BT and B2 each containing 30 cartridges D are stored in the casing 1 of the automatic playback apparatus A as shown in FIG. On this occasion,
If the disk storage rank B (81, 82) is not placed correctly in the predetermined position of the placement member 38, the process shown in FIG. 8(B)
As shown in , the protruding shaft 40 of the locking mechanism 41 is pressed against the bottom surface of the disc storage rack B and descends. This results in
Since the locking piece 45 corresponds to the protrusion 46 of the device,
This disk storage rank B cannot be loaded into the device.

In addition, when the disk storage rack B is correctly placed on the mounting member 38, the protruding shaft 4
0 is inserted into the recess 37 at the bottom. Therefore, since the locking piece 45 does not descend, the correspondence relationship with the protrusion 46 is avoided, and the disk storage rack B is not prevented from entering the apparatus. And each disc storage rack B+.

When B2 reaches the final rest position of the device as shown in FIG. 1, the arm 3 of the shutter mechanism 30 is moved as shown in FIG.
4b is locked to the protrusion 36 of the device, the shutter 35 moves and the concave groove n 31 is opened.

■Here, operate a button (not shown) on the device to select the disk storage rack B1. When one cartridge D stored in B2 is selected, a control signal from the control device II shown in FIG. 1 causes the unit base 48 as shown in FIG. The shaft 47a to the position of the storage rack, for example, the upper rack B1,
47b vertically at a predetermined speed.

During operation of this elevating mechanism G, a sensor assembly 111 having the same structure as the sensor assembly 74 shown in FIG. 12 fixed to one end of the unit base 48 is shown in FIG. 15 formed on the inner wall of the housing 1. The robot moves up and down while detecting the control pattern shown in the figure.

That is, the cartridge ejection position of the upper and lower disk storage racks B+ and B2 corresponding to the sensor assembly 111 is 1.15 mm.
In addition, four types of patterns 109a, 109b, 109 are provided at the cartridge insertion position of each playback device C1, C2 so that the disk insertion/ejection means J of the carrier mechanism F can be accurately stopped.
c and 109d are vertically aligned along the moving direction of the carrier mechanism F. Therefore, if the control signal for the carrier mechanism F from the control device ① indicates the position of the upper disk storage rack B1, the sensor assembly 111 will be in the pattern 109.
The carrier base 54 is moved at a predetermined speed until a is detected. In addition, in FIG. 15, 110 is a pattern 109a.
, 109b, 109c, and ' 109d. During this time, the microcomputer continues the previous movement of the carrier base 54.
When the desired pattern position is reached, the sensor assembly 111 detects the pattern shape and moves the carrier base 5
4 locates the deceleration and stop position. Furthermore, by forming the patterns 109a to 109d via the straddle sensor 110 in this way, even after the disc storage rack and the playback device are set in the housing 1, one divided pattern is generated when the stop position is adjusted. can be easily adjusted as appropriate. Therefore, when positioning the carrier base 54,
Easily adjust heavy disc storage racks and playback equipment without moving them.

One way to perform deceleration and stop position is, for example, as shown in FIG. 15, by using one pattern 109a of τ as four sensor tracks T1 to T4, and when the carrier base 54 changes from the normal speed to the deceleration mode, the sensor is activated. By setting the deceleration pattern r to a wide range so that it can be read, and by setting the stop pattern S to a narrow range at positions where each track pattern overlaps and at positions where each track pattern is discontinuous, the carrier base 54 is connected to the sensor assembly 111. The position will be controlled accurately by

- Simultaneously with the movement of the carrier base 54, the motor 60 of the selection drive mechanism H is driven, and the timing belt 70 moves the carrier base 54 that has reached a predetermined disk storage rack B (for example, B+) according to a control signal (channel selection signal). Accordingly, the horizontal direction (XI, X2
) to reach the predetermined cartridge D position. The movement of the carrier base 54 is controlled by moving a pattern 73 provided on the upper end of the base portion 52 and having a shape similar to the pattern shown in FIG. 15 as shown in FIG.
The sensor 85 of the sensor assembly 74 having the configuration shown in the figure detects the information, thereby allowing control such as deceleration and stopping.

(4) Then, the carrier base 54, which has been moved to the predetermined position of the cartridge D, drives the pinion gear 92.degree. 92 as the motor 94 is driven, as shown in FIG. As a result, the board 93 on which each mechanical element is mounted moves in the Z+ force direction to take out the cartridge D. This board 9
3 moves in the direction 71, the cam 100 that controls the opening and closing of the clamper 96 is in operation against the elastic force of the coil spring 98, so the upper and lower flaps 96a and 96b expand as shown by the solid line. It is in the open state.

When the clamper 96 is expanded, the cam 9 of the cam gear 99
9a releases the pulling force in the 72 direction of the flange 112 that locks the rear end of the pusher bottle 106, and the pusher bottle 106 moves in the 71 direction by the elastic return force of the coil spring 108.
protrudes in the direction.

(ω From the above state, the clamper 96 of the cartridge insertion/removal mechanism J moves in the 71 direction in the expanded state with the movement of the board 93. Then, when the cartridge insertion/removal mechanism J reaches the predetermined clamping position of the cartridge D, A sensor (not shown) detects this state, and the detection signal drives the motor 101 that operates the clamper 96, causing the clamper 96 to move to the first position.
The coil spring 98 is closed by the elastic force of the coil spring 98 as shown by the dashed dotted line in FIG. 1, and the desired cartridge D is clamped as shown in FIG. 14(A). At this time, since the push-out bottle 1O6 is moved in 72 directions by the rotation of the cam 99a, the pressing force of the coil spring 108 is not applied to the cartridge D within the clamper 96. Thereafter, the motor 94 is reversely rotated and the substrate 93 is moved in the 22 directions. When the substrate 93 is moved in the 72 direction, the desired cartridge D clamped by the clamper 96 is introduced into the guide hole 71a of the guide plate 71 of the carrier base 54 as shown in FIG. As shown, it is accommodated in the guide groove 88 of the arm portion 54b. Then, the motor 94 is stopped when a sensor (not shown) provided on the substrate 93 detects a predetermined position in 72 directions.

(2) Thereafter, the carrier base 54 containing the cartridge D is driven by the elevating mechanism G and the selection drive mechanism H to set the stop pattern 109G of the playback device ffc+.
It descends and decelerates at a predetermined speed until it detects. When this elevating mechanism G operates, the carrier base 54
In order to move the carrier base 54 to the correct loading position of the playback device G+, the carrier base 54 is moved in the x1 and x2 directions as appropriate, and the motor 53 is driven at a slightly delayed timing.
The cartridge D is brought into a horizontal state by rotating approximately 90 degrees. Note that since information is recorded on both sides of the disk 10, the rotation direction of the carrier base 54 is appropriately selected according to the selected signal. Further, the rotational position of the carrier base 54 is controlled by a motor 5 shown in FIGS. 9 and 10.
The rotation angle of the pattern disk 57 on which the pattern is formed as shown in FIG.
) is controlled by detection. That is, the pattern circle 157 has three patterns 57a+ formed concentrically.
, 57a2.57a:+, and
The circumference is divided into eight parts so that eight states can be detected. Therefore, each pattern 57a+, 57a2, 57a*
The rotation state of the carrier base 54 is precisely detected by the sensor 58 shown in FIG. 9 above. In addition,
The pattern disk 57 rotates the carrier base 54 by 9 rotations.
It is set to rotate 0'.

Furthermore, a sensor and a pattern (both not shown) are provided on the facing surfaces of the base 54a of the carrier base 54 and the base portion 52 that supports it, and the vertical position of the carrier base 54 @( The initial position) is precisely controlled in attitude along with the 1/8 pattern of the pattern disk 57.

(2) When the carrier base 54 is in a horizontal state, the motor 101 of the cartridge insertion/removal means J is driven in the same manner as in the operation to take out the cartridge D from the disk storage rack B1, and the clamper 96 is operated again as shown in FIGS. 11 and 14. Expand as shown in (B). At this same time,
The motor 94 that drives the substrate 93 is driven, and the cartridge D moves in the z1 direction in the guide groove 88 as the substrate 93 moves, with the rear end supported by the pusher bottle 106 .

As shown in FIG. 13, the leading end of the cartridge D reaches the guide section 18 of the playback device C+ (C), and at the same time, the rear end reaches the guide groove 88. Since the width of the cartridge D reaches the wide part of the central portion 88b, when the loading posture is restricted by the tapered portion 18a, the rear end portion is allowed to rotate within the central portion 88b. Reliable loading operation is guaranteed.

(2) When the cartridge D is loaded into the device C from the state shown in FIG. 13 as shown in FIG. When the clamper 96 clamps the sleeve 2 again as shown in FIG. 14(A), at the same timing, the motor 94 is driven and the board 93 moves in the Z2 direction to move the empty sleeve 2 as shown in FIG. As shown, it is housed in the guide groove 88 of the carrier base 54. and,
In response to the play signal, the clamp mechanism 16 of the playback device C releases the clamp as shown in FIG. It will be installed.

Here, the disc 10 rotates together with a turntable 19 rotated by a motor, and is played back by a pickup means 23 that moves in the direction of arrow P.

On the other hand, the carrier base 54 is controlled to have a vertical posture as shown in FIG. Rack B1
The empty sleeve 2 is stored in the open concave groove n31.

(2) Thereafter, the carrier base 54 is driven by each of the drive mechanisms and components described above so that the next desired cartridge D1, for example, a disc in the disc storage rack B2, is loaded into another playback device C2 in response to an operation signal. In the same manner as above, a disc is loaded into the second recycling bag @C2 and placed on standby.

(2) When the playback mode state of the playback device C1 ends, the playback mode state of the playback device C2 continues. At this time, on the playback device C1 side, as shown in FIG. 2, the disk 10 stops rotating, and contrary to the above case, the support ring 22 rises and the clamp mechanism 16 operates, and the disk 10 is moved to the turntable 19. is supported in the upper position.

In this state, when the empty sleeve 2 is inserted into the playback device C using the cartridge insertion/removal means J and pulled out in the same way as the loading operation described above, the disk 10 is moved together with the lid 3 by the accumulated elastic force. It is stored so as to protrude into the sleeve 2 at a position before loading. As a result, the disc 10 is collected into the cartridge D and the playback device C1
It is taken out from inside and correctly returned to its original storage position in the original disk storage rack Bi.

In this way, when a desired disc is selected by the operation signal, the disc in the cartridge D in the predetermined disc storage rack is automatically loaded into the playback device (-) and played, and by the next signal, The carrier base moves to a predetermined disk storage rack so as to select the next disk to be played, loads the selected cartridge D into another playback device, and stands by in a state where the disk can be played. Therefore, according to the automatic playback device of the present invention, the entire operation from loading the disc to collecting the disc can be performed automatically, ensuring reliable operation and preventing damage to the disc and the playback device. There isn't.

(Effects of the Invention) As described in detail above, according to the information recording medium automatic selection and playback device of the present invention, all consistent operations from disc loading to disk collection can be performed automatically, so that conventional manual playback devices cannot be used. In comparison, the operation is simple, and the regeneration device can perform continuous regeneration unattended without applying excessive operating force from the operator, and the clamping means and the pressing member that elastically presses the cartridge can be operated by a single operation. Since the cartridge is operated by a motor, the cartridge can be reliably clamped and pressed, improving the reliability of the device.
