(4) Operation of Disc Loading Device The operation of the disc loading device 1 will be described below (see FIGS. 37 to 95).

In the disc loading device 1,
.. and feeding members 10, 10, ...
.Disc-shaped recording medium 20 sandwiched by and
0 is transported.

(A) Conditions for Transport First, the feed rollers 9, 9, ... And the feed members 10, 10, which are necessary for transporting the disc-shaped recording medium 200.
.. will be described (see FIG. 37).

.. and feeding body 1
0, 10, ... Are the respective slide means 24, 29, 4
Spring members 27, 32, 46, 51 supported by 3, 48
Are pressed against the outer peripheral surface of the disc-shaped recording medium 200, and the disc-shaped recording medium 200 is separated between the feeding rollers 9, 9, ... And the feeding bodies 10, 10 ,. It is transported while being delivered.

When the spring force of the spring member is X, the friction coefficient between the feed roller (feed member) and the disc-shaped recording medium is μ, and the vertical force received by the feed roller from the disc-shaped recording medium is N, Xsin θ = The conditional expression of μN holds. However, θ is a line segment L2 that passes through the center P and is orthogonal to the line segment L1 when the line segment that passes through the center P of the disk-shaped recording medium and extends in the transport direction S is L1, and the center of rotation of the center P and the feed roller. It is an angle formed by a line segment L3 connecting with Q (hereinafter, the angle θ is referred to as a “contact angle”). N = Xcos
Since θ, Xsin θ = μX cos θ holds, sin θ = μ cos θ, and μ = tan θ.
Therefore, as the contact angle θ increases, the friction coefficient μ must increase, and the feed roller becomes slippery with respect to the disc-shaped recording medium.

As described above, whether or not the feed roller slides on the disk-shaped recording medium is independent of the spring force X.
Depends on friction coefficient μ. Therefore, in order to reliably carry the disc-shaped recording medium, it is preferable that the contact angle θ is as small as possible, and when the disc-shaped recording medium is passed from the feed roller and the feeding body to the next feeding roller and the feeding body, It is desirable that the feed roller and the feed body that are delivered are separated from each other as much as possible and that the distance from the line segment L1 along the transport direction S is large.

On the other hand, when the disc-shaped recording medium is conveyed, the spring force X is resisted by the feed roller and the feed member until the centers of the feed roller and the feed member coincide with the line segment L2. However, after the centers of the feed roller and the feed body coincide with the line segment L2, the feed roller and the feed body move in the approaching direction by the spring force X. As they are processed, they help the transportation.

(B) Five operation modes In the disk loading device 1, five operation modes are set in the following operations.

The five operation modes are the transport mode when the disc-shaped recording medium 200a or the disc-shaped recording medium 200b is transported between the disc insertion slot 2a and the reproducing section 3, and the stocker 4 is moved up and down.

The third cam wall 98 is located behind the support shaft 144 that supports the first slider 3 of the third slide means 34.
It is located behind the guided shaft 39 supported by the motor 5 (see FIG. 38). The fourth cam wall 99 of the mode slider 91 has a front linear portion 99a engaged with a support shaft 164 supporting the fifth feed roller 9i from the right side (FIG. 3).
8). At this time, the support shaft 164 makes elastic contact with the front linear portion 99a of the fourth cam wall 99 by the spring member 51 and the biasing spring 167 that bias the fifth slide means 48 and the fourth swing mechanism 156 to the right. Has been done. The pressing protrusion 100 of the mode slider 91 is located behind the operated portion 128 of the operation lever 125 supported by the sub chassis 120 (see FIG. 38). The left end of the inclined surface 101a of the cam protrusion 101 of the mode slider 91 is engaged with the support shaft 166 that supports the sixth feed roller 9k (see FIG. 38).

The base unit 102 includes the support case 10
The third cam protrusion pin 104b is engaged with the lower horizontal portion 68a of the cam groove 68 of the cam member 67 (see FIG. 41). Therefore, the base unit 102 is the disk table 10
8 is located at the lower moving end and the base chassis 1
It is inclined with respect to 5.

Since the base unit 102 is inclined, the peeling member 57 is rotated by the engaging portion 105b of the engaging lever 105 in the direction in which the lifting portions 59, 59 are moved upward, and is chucked by the peeling member 57. The pulley 56 is lifted up (see FIG. 41). Therefore, a space having a predetermined size is formed between the chucking pulley 56 and the disc table 108.

(D) Transporting operation between the disc insertion slot and the stocker Next, the disc-shaped recording medium 200a is inserted into the disc insertion slot 2
The operation when the sheet is conveyed between the a and the stocker 4 will be described (see FIGS. 42 to 71).

When the disc-shaped recording medium 200a is inserted from the disc insertion opening 2a and conveyed to the stocker 4 for storing, a storage knob (not shown) is operated.
When the storage knob is operated, the raising / lowering mode for first raising / lowering the stocker 4 is set. At this time, a desired disk storage unit 181 in which the disk-shaped recording medium 200a is to be stored is selected from the disk storage units 181, 181, ... Of the stocker 4. The state of each part in the lifting mode is as follows (FIGS. 42 to 4).
4).

Each slide means 24, 29, 34, 43,
The state of 48 is the same as the state in the transport mode described above.

The cam member 67 supported on the lower surface of the base chassis 15 rotates a predetermined angle in the counterclockwise direction (R2 direction shown in FIG. 42) when seen in a plane by the rotation of the mode motor 61 from the state of the transport mode. One of the action pins 67b is engaged with the actuated groove 70 of the Geneva driven gear 69.
It is stopped at the position immediately before being inserted into d (see FIG. 42).

The insertion restricting means 77 arranged on the lower surface side of the base chassis 15 has a counterclockwise direction when viewed in a plane when the action gear 74 rotates as the cam member 67 rotates (see P in FIG. 42).
Since it is rotated in two directions, the pressing of the actuating lever 80 by the pressing pin 76 toward the pressed protrusion 87a to the rear side is released (see FIGS. 42 and 43). At this time, in the action gear 74, the notch 75a for insertion of the restriction wall 75 is not positioned to the left. Therefore, the support shaft 135 supported by the drive-side slider 25 of the first slide means 24 regulates the movement by the regulation wall 75 even if the support shaft 135 tries to move to the left as the drive-side slider 25 moves to the left. The insertion notch 75a cannot pass through, and the driving slider 25 is in a locked state in which it cannot move in the left-right direction (see FIGS. 42 and 43).

In the locked state of the driving side slider 25, the disc-shaped recording medium 200a is set in the reproducing section 3 in addition to the elevating mode.
Storage / unloading mode when transported between the storage unit 4 and the stocker 4, the disc-shaped recording medium 200a transported to the reproducing unit 3
And a chucking mode for chucking or unlocking the disk-shaped recording medium 200a
The unlocked state in which the drive side slider 25 is movable is also set in the disc holding release mode in which the holding by the feed rollers 9 and 9 and the feed bodies 10 and 10 is released or held again. Is set.

Therefore, the restriction wall 75 of the action gear 74 serves as a restriction means for restricting the movement of the driving slider 25 in the operation modes other than the transport mode.

In the disc loading device 1,
In the operation modes other than the transport mode, the locked state in which the drive-side slider 25 cannot be moved is set, so that the erroneous insertion of the disc-shaped recording medium 200 in the operation modes other than the transport mode can be reliably prevented.

In the insertion regulating means 77, the pressing pin 7
Since the rearward pressing of the pressed projection 87a by 6 is released, the spring force of the compression coil spring 88 causes
The regulating lever 79 is rotated in a direction in which the engaging protrusions 84a, 84a are moved upward, and the regulating pin 89 is moved upward by the urging force of the compression coil spring 88, so that the regulating pin 89 is moved.
Is positioned in front of the disc insertion opening 2a (see FIG. 43). Therefore, in the ascending / descending mode, the disc-shaped recording medium 200a is in a restricted state in which the disc-shaped recording medium 200a cannot be inserted or taken out. At this time, the operating lever 80 moves the pressed pin 84 of the regulating lever 79.
The lever protrusion 87 is pressed forward by b, and the lever protrusion 87 is in a state of extending left and right (see FIGS. 42 and 43).

In the restricted state in which the disc-shaped recording medium 200a cannot be inserted into or ejected from the disc insertion opening 2a, the disc-shaped recording medium 200a is not limited to the raising / lowering mode,
Storage / unloading mode when transported between the storage unit 4 and the stocker 4, the disc-shaped recording medium 200a transported to the reproducing unit 3
And a chucking mode for chucking or unlocking the disk-shaped recording medium 200a
It is also set in the disc holding release mode in which the holding by the feeding rollers 9, 9 and the feeding bodies 10, 10 is released or held again, and the disc-shaped recording medium 200a can be inserted into or taken out from the disc insertion opening 2a. Is set only in the transport mode.

In the disc loading device 1,
Since the locked state of the drive-side slider 25 is set as described above, the disc-shaped recording medium 200a can be prevented from being conveyed in a mode other than the conveying mode. It is possible to insert the disc-shaped recording medium 200 from the disc insertion opening 2a until the sheet comes into contact with the first feed roller 9a and the first feed body 10a. At this time, for example, when the disc-shaped recording medium 200 exists in the reproducing unit 3, the disc-shaped recording medium 200 existing in the reproducing unit 3 is present.
The outer peripheral portion of the disk-shaped recording medium 200 may come into contact with the outer peripheral portion of the disk-shaped recording medium 200 to be inserted from the disk insertion port 2a, and the disk-shaped recording media 200 and 200 may be damaged.

Therefore, in the disc loading device 1, the locked state of the driving slider 25 and the regulated state in which the disc-shaped recording medium 200 cannot be inserted or taken out from the disc insertion opening 2a are set at the same time.
The disc insertion opening 2 on the outer periphery of the disc-shaped recording medium 200
The insertion from a is also prevented (see FIG. 44).

As described above, when the locked state is set, at the same time, the restricted state in which the disc-shaped recording medium 200 cannot be inserted from the disc insertion opening 2a is set. Disc insertion slot 2a
Is prevented, and even if the disc-shaped recording medium 200 being reproduced is present in the vicinity of the disc insertion opening 2a, contact between the disc-shaped recording media 200, 200 can be avoided, and in the elevating mode, the mode slider Reference numeral 91 is located at the rear end of the movement as in the transport mode (see FIG. 42).

The base unit 102 is inclined with respect to the base chassis 15 with the disk table 108 positioned at the lower moving end, as in the transport mode.

When the raising / lowering mode described above is set, then the raising / lowering motor 168 is rotated so that the desired disc storage portion 181 selected during the operation of the storage knob is moved to the storage / ejection position. .

When the lifting motor 168 is rotated, as described above, the rotary cam 1 moves in the direction corresponding to the rotation direction.
76, 176, 176 are rotated, and the cam groove portions 17 of the guided protrusions 179a, 179a, 179a of the stocker 4 are rotated.
The positions with respect to 7, 177, and 177 are changed, and the stocker 4 is moved up and down. For example, when the selected disc storage portion 181 is located at the uppermost end, the stocker 4 is moved to the lower movement end, and the disc storage portion 181 is moved.
Is positioned directly behind the sixth feed roller 9k and the sixth feed body 10k, that is, at the storage and take-out position (see FIG. 45). When the selected disc storage portion 181 is located at the lowermost end, the stocker 4 is moved to the upper moving end, and the disc storage portion 181 is located at the storage / ejection position (see FIG. 46).

As described above, since the stocker 4 is lifted and lowered by the rotation of the rotary cams 176, 176 and 176, the rack and the lifters are lifted up and down as in the case where the rack and the lifting gears are used to move up and down. The precision of the stop position of the stocker 4 does not vary due to the backlash between the gear and the gear, and the precision of the stop position of the stocker 4 can be improved.

The guided projection 179 of the stocker 4
a, 179a, 179a are rotary cams 176, 176, 1
Since the stocker 4 is stopped regardless of which portion of the non-acting portions 177a, 177a, 177a of the 76 is engaged, it is not necessary to strictly set the precision of the rotation control of the rotating cams 176, 176, 176. Therefore, the rotation control of the lifting motor 168 by the rotary encoder 174 can be facilitated.

As described above, when the stocker 4 is moved up and down and the desired disc storage portion 181 is positioned at the storage / ejection position, the mode motor 61 is then rotated to set the transport mode. When the transport mode is set,
As described above, the notch 75a for insertion of the action gear 74 is positioned on the left side of the support shaft 135 supported by the drive-side slider 25 of the first slide means 24 to be in the unlocked state, and the regulation pin 89 is It is lowered to the non-regulated state (see FIGS. 39 and 40).

The receiving portions 23b, 23b and the disk guide portions 15t, 15t provided on the upper surface of the base chassis 15 are moved in the state of being close to or in contact with them (see FIG. 62). Therefore, it is possible to prevent the disc-shaped recording medium 200a from being tilted at the time of conveyance and to improve the reliability of the conveying operation.
Since the portion of a other than the recording surface contacts the disc guide portions 23, 23 and the disc guide portions 15t, 15t, damage to the recording surface can be avoided.

Further, in the disc loading device 1, the disc-shaped recording medium 200 is constituted by the disc guide portions 23, 23 and the disc guide portions 15t, 15t.
Since a is supported in the thickness direction, the inclination of the disk-shaped recording medium 200a can be reliably prevented.

In the disc loading device 1, the disc guide portions 23, 23 and the disc guide portion 15t are provided in order to prevent the disc-shaped recording medium 200a from being tilted when being conveyed between the reproducing portion 3 and the stocker 4. ,
Although 15t is provided, the disc insertion slot 2a and the reproducing section 3 are provided.
A disc guide portion may be provided on the support chassis 14 or the base chassis 15 for preventing the disc-shaped recording medium 200a from being tilted during the transportation between the two.

The disc-shaped recording medium 200a is retracted only by the rotation of the sixth feed roller 9k, and is accommodated in the disc accommodating portion 181 of the stocker 4 on standby (see FIG. 63). When the disc-shaped recording medium 200a is housed in the disc housing portion 181, the rotation of the drive motor 110 is stopped.

When the disc-shaped recording medium 200a is accommodated in the disc accommodating portion 181, the sixth force is exerted by the spring force of the spring member 51 which urges the driving slider 49 and the driven slider 50 toward each other. The feed roller 9k and the sixth feed member 10k are elastically contacted with the outer peripheral surface of the disc-shaped recording medium 200a (see FIG. 64). Therefore, the sixth feed roller 9k and the sixth feed member 10k prevent the disc-shaped recording medium 200a from falling off the disc storage portion 181. At this time, the moving levers 53, 53 are located at pivot ends in directions toward each other, and the abutting stop portions 55, 55 are located in contact with or close to the outer peripheral surface of the disk-shaped recording medium 200a.

When the eject knob (not shown) is operated in the state where the disc-shaped recording medium 200a is accommodated in the disc accommodating portion 181 as described above, the disc-shaped recording medium 200a is moved from the stocker 4 to the disc insertion opening 2a.

When the handed-over side is the (m + 1) th side, the carrying operation may be surely performed as follows.

In the state where the disc-shaped recording medium 200 is conveyed from the disc insertion opening 2a to the stocker 4, the diameter of the (m + 1) th feeding member 10 is set to the mth feeding roller 9 and the (m + 1) th feeding roller. The diameter of the 9th and the mth feeding body 10 is made smaller (see FIG. 66), or the diameter of the mth feeding body 10 is set to the mth feeding roller 9, the m + 1th feeding roller 9, and the mth + 1. It is made larger than the diameter of the th feed body 10 (see FIG. 67), or the diameter of the m + 1 th feed roller 9 is set to the m th feed roller 9, the m th feed body 10, and the m + 1 th feed body. It is possible to use a means of making the diameter larger than 10 (see FIG. 68).

In the state where the mode slider 91 is moved to the moving end on the front side, the supporting projections 95, 95 of the mode slider 91 are the supporting pieces 1 of the base unit 102.
04c is sandwiched from above and below (FIG. 73).
reference). Therefore, the base unit 102 is stably held at the upper rotating end, and the disc-shaped recording medium 20 is held.
The surface wobbling of the disc-shaped recording medium 200a is prevented in the reproducing operation of the information signal described later with respect to 0a, and the reliability of the reproducing operation can be improved.

In the disc holding release mode, the support shaft 144 is engaged with the straight portion 96b of the first cam wall 96, and the supported shaft 39 is engaged with the straight portion 98b of the third cam wall 98 to support. The shaft 164 is engaged with the rear straight portion 99e of the fourth cam wall 99, and the support shafts 154 and 166 are respectively located at the left side moving ends (see FIG. 78). Therefore, the third feeding roller 9e and the fourth feeding roller 9e

(See FIGS. 78 and 79). Therefore,
The disc-shaped recording medium 200a is a disc table 108.
It is brought into a state in which it can smoothly rotate with the rotation of.

As described above, when the other action pin 67b of the cam member 67 is inserted into the action groove 70e of the Geneva driven gear 69, the action pin 67b is acted upon in the initial stage and the final stage. Since the portion of the wall portion forming the groove 70e located on the outer peripheral side of the Geneva driven gear 69 is pressed, the load applied from the Geneva driven gear 69 to the action pin 67b may be small, and in the middle stage, Since the action pin 67b presses a portion of the wall portion forming the actuated groove 70e, which is located on the central portion side of the Geneva driven gear 69, the load applied from the Geneva driven gear 69 to the action pin 67b is large.

Therefore, in the disc loading apparatus 1, in the initial stage and the final stage, as described above, the support shaft 144, the supported shaft 39, and the support shaft 164 each have a first inclination. The front side portion 96c or the rear side portion 96e of the cam wall 96, the front side portion 98c or the rear side portion 98e of the third cam wall 98, and the front side portion 99i or the rear side portion 99k of the fourth cam wall 99 are slidably contacted. In the middle stage, the support shaft 144, the supported shaft 39, and the support shaft 164 respectively have an intermediate portion 96d of the first cam wall 96 with a gentle slope.
The intermediate portion 98d of the third cam wall 98 and the intermediate portion 99j of the fourth cam wall 99 are slidably contacted (see FIGS. 74 to 76). Therefore, the action pin 67b of the cam member 67
Therefore, the load on the mode motor 61 can be reduced.

As described above, when the mode is switched from the transport mode or the elevating mode to the storage / unload mode, one of the action pins 67b of the cam member 67 is inserted into the actuated groove 70d of the Geneva driven gear 69. The Geneva driven gear 69 is rotated by 90 °, the mode slider 91 is moved, and the support shaft 164 that supports the fifth feed roller 9i.
Is in sliding contact with the front side inclined portion 99b of the fourth cam wall 99 of the mode slider 91. Even in this operation, the support shaft 164 is slidably contacted with the steeply inclined front side portion 99f or rear side portion 99h at the initial stage and the final stage when the action pin 67b is inserted into the actuated groove 70e, In the middle stage, the support shaft 164 is slidably contacted with the gently-sloping intermediate portion 99g. Therefore, even during this operation, the cam member 67
The load on the action pin 67b is reduced, and the load on the mode motor 61 can be reduced.

Further, in the disc loading device 1, as described above, the action pin 67 of the cam member 67 is used.
b and 67b are actuated grooves 70d and 7 of the Geneva driven gear 69.
When inserted in 0e, the Geneva driven gear 69 is rotated and the mode slider 91 is moved to set each operation mode. Accordingly, the action pins 67b and 67b are pulled out from the actuated groove 70d or the actuated groove 70e, so that the mode slider 91 is stopped and each operation mode is set. Therefore, each operation mode is set to the Geneva driven gear 69.
Any of the wall portions 70a, 70b, 70c of the
If any of the ridges 67c, 67c is positioned corresponding to the ridges 67c, 67c, it is set. Therefore, the stop position of the mode slider 91 does not largely depend on the stop position of the mode motor 61, and the accuracy of the stop position of the mode slider 91 can be improved. In particular, like the disc loading device 1, the driving force of the mode motor 61 is transmitted through the plurality of gears such as the gear group 65 and the mode slider 9 is used.
In the case of a device having a mechanism in which the backlash between gears is large, the movement of the mode slider 91 is controlled by using the Geneva driven gear 69 to improve the accuracy of the stop position of the mode slider 91. Very effective above.

When the disk holding release mode is set,
The disk table 108 is rotated by the rotation of the spindle motor, the optical pickup 107 is operated, and the reproducing operation is performed on the chucked disk-shaped recording medium 200a. During the reproducing operation, the laser light emitted from the light-emitting element (not shown) of the optical pickup 107 is applied to the disc-shaped recording medium 200a via the objective lens 107a, and the returned light is the objective lens 107a.

Is transported in this manner. The disc-shaped recording medium 2
The transport operation from the reproduction section 3 of the disc 00a to the disc insertion slot 2a is the same as the transport operation from the disc insertion slot 2a to the reproduction section 3 described in "(d) Transport operation between the disc insertion slot and stocker". Therefore, a brief description will be given.

When the eject knob is operated, the mode motor 61 is rotated in the opposite direction to the direction R1 shown in FIG. When the cam member 67 is rotated in the R1 direction by the rotation of the mode motor 61, the mode slider 91 is moved rearward, and the support shaft 144 supporting the third feed roller 9e is moved to the first cam wall 96.
Is slidably contacted from the straight line portion 96b toward the inclined portion 96a, and the supported shaft 39 penetrating the receiving member 38 provided below the first regulating roller 37 causes the straight line portion 98 to pass through the third cam wall 98.
The support shaft 164 that slides from b to the inclined portion 98a supports the fifth feed roller 9i so that the fourth cam wall 99 slides from the rear linear portion 99e toward the intermediate linear portion 99c. . At this time, at the same time, the pressing protrusion 100 releases the pressed portion 128 of the operating lever 125 supported by the sub-chassis 120.

When the rotation of the drive motor 110 is stopped, then the mode motor 61 is rotated. The mode motor 61 is rotated in the direction in which the cam member 67 is rotated in the R2 direction shown in FIG.

When the cam member 67 is rotated by the rotation of the mode motor 61, the chucking mode is set similarly to the case of the disc-shaped recording medium 200a, and the disc-shaped recording medium 200b is set to the table portion 108a of the disc table 108. It is sandwiched by the stabilizer portion 56b of the chucking pulley 56 and chucked. At this time, the peeling member 57 supported by the support chassis 14 is lifted by the lifting portions 59, 5 while the operated portion 60 is engaged with the engagement lever 105 of the base unit 102.
9 is located below the flange portion 56 a of the chucking pulley 56.

The mode motor 61 is continuously rotated, and the rotation of the cam member 67 moves the mode slider 91 further forward (see FIG. 88). As the mode slider 91 is moved forward, the support shaft 144 supporting the third feed roller 9e moves to the second cam wall 97.
The support shaft 164 that supports the fifth feed roller 9i is slidably contacted with the fourth cam wall 99. At the same time, the action lever 125 supported by the sub-chassis 120
The operated portion 128 of is pressed forward by the pressing protrusion 100.

As described above, since the support shaft 144 is brought into sliding contact with the second cam wall 97, the third feed roller 9
e is separated outward from the outer peripheral surface of the disk-shaped recording medium 200b (see FIGS. 89 and 90). When the actuated portion 128 of the action lever 125 is pressed by the pressing protrusion 100, the action lever 125 is rotated in the direction in which the actuated portion 128 is moved substantially forward and is inserted into the support elongated hole 126b. The supported support shaft 154 is guided by the guide hole 121c of the sub chassis 120 and is moved leftward.
By moving the support shaft 154 to the left, the drive-side slider 44 of the fourth slide means 43 is moved to the left, and the driven-side slider 45 is synchronously moved to the right. It

When the driven slider 45 of the fourth slide means 43 is moved rightward, the driven slider 36 of the third slide means 34 is moved by the pressing protrusion 45c.
The pressed projection 36c is pressed to the right, and the drive-side slider 35 and the driven-side slider 36 are synchronously moved in the direction in which they are separated from each other. Therefore, the first regulation roller 37 and the second regulation roller 41 are moved in the direction in which they are separated from each other, and are separated outward from the outer peripheral surface of the disk-shaped recording medium 200b (see FIG. 89).

As described above, when the mode slider 91 is moved, as in the case where the disc-shaped recording medium 200a is chucked, the other action pin 67b of the cam member 67 is actuated into the actuated groove of the Geneva driven gear 69. When inserted in 70e, in the initial stage and the final stage, the support shaft 144 and the support shaft 164 respectively have a steeply inclined front side portion 97c of the second cam wall 97 and a front side of the fourth cam wall 99. In the middle stage, the support shaft 144 and the support shaft 164 respectively have a gentle inclination in the middle portion 97d of the second cam wall 97 and the middle portion 99j of the fourth cam wall 99. It will be slid on. Therefore, the load on the action pin 67b of the cam member 67 is reduced, and the load on the mode motor 61 can be reduced.

When the mode slider 91 is moved to the front moving end, the disc holding release mode is set, and the mode slider 9 is set in the same manner as when the reproducing operation is performed on the disc-shaped recording medium 200a.
The supporting protrusions 95, 95 of the first supporting member 104c of the base unit 102 are sandwiched in the vertical direction.
Therefore, the base unit 102 is stably held at the upper rotation end, the surface wobbling of the disc-shaped recording medium 200b is prevented in the reproducing operation of the information signal described later with respect to the disc-shaped recording medium 200b, and the reliability of the reproducing operation is improved. It is possible to improve the sex.

In the disk holding release mode, the third
The feed roller 9e, the first regulation roller 37, the third feeding body 10e, and the second regulation roller 41 are separated from the outer peripheral surface of the disc-shaped recording medium 200b (see FIG. 89), and the disc-shaped recording medium 200b is the disc. As the table 108 rotates, the table 108 can be smoothly rotated.

When the disc holding release mode is set,
The disk table 108 is rotated by the rotation of the spindle motor, the optical pickup 107 is operated, and the reproducing operation is performed on the chucked disk-shaped recording medium 200b. During the reproducing operation, the laser light emitted from the light-emitting element (not shown) of the optical pickup 107 is applied to the disc-shaped recording medium 200b via the objective lens 107a, and the returned light is the objective lens 107.
The information signal which is incident on a light receiving element (not shown) of the optical pickup 107 via a and recorded on the disk-shaped recording medium 200b is reproduced.

When the eject knob (not shown) is operated in the state where the reproduction operation of the information signal for the disc-shaped recording medium 200b is completed, the disc-shaped recording medium 200b is moved from the reproducing section 3 to the disc insertion opening 2a as follows. Is transported in this manner. The disc-shaped recording medium 2
The transport operation of the disc 00b from the reproducing unit 3 to the disc insertion port 2a is the reverse of the above-described transport action from the disc insertion port 2a to the reproducing unit 3, and thus will be briefly described.

When the eject knob is operated, the mode motor 61 is rotated in the opposite direction to the above and the cam member 6 is rotated.
7 is rotated in the R1 direction shown in FIG. When the cam member 67 is rotated in the R1 direction by the rotation of the mode motor 61, the mode slider 91 is moved rearward, and the support shaft 144 supporting the third feed roller 9e moves the second cam wall 97. The support shaft 164, which is slidably contacted from the linear portion 97b toward the inclined portion 97a, supports the fifth feed roller 9i and slidably contacts the fourth cam wall 99 from the rear linear portion 99e toward the intermediate linear portion 99c. To be done. At the same time, the action lever 125 supported by the sub-chassis 120
The pressure applied to the actuated portion 128 by the pressing ridge 100 is released, and the drive side slider 44 and the driven side slider 45 of the fourth slide means 43 are moved in a direction in which they approach each other. By moving the drive-side slider 44 and the driven-side slider 45 in directions approaching each other,
The pressing projection 45c of the driven slider 45 releases the pressing of the second slider 36 against the pressed projection 36c, so that the driving slider 35 and the driven slider 36 of the third slide means 34 are separated from each other by the spring member 46. Are moved in the directions in which they approach each other by the spring force, and the first regulation roller 37 and the second regulation rollers 41 move in the direction in which they approach each other. Therefore, the third feeding roller 9e, the first regulation roller 37, the third feeding body 10e and the second regulation roller 41 are in contact with the outer peripheral surface of the disc-shaped recording medium 200b, and the disc-shaped recording medium 200b is the third. It is held by the feed roller 9e and the third feed body 10e.

At this time, the cam projecting pin 104b of the base unit 102 is located at the upper horizontal portion 6 of the cam groove 68 of the cam member 67.
8c is relatively moved toward the slanted portion 68b.

The mode motor 61 is continuously rotated, and the cam projection pin 104b of the base unit 102 moves from the upper horizontal portion 68c of the cam groove 68 of the cam member 67 to the slant portion 68.
It is relatively moved to the lower horizontal portion 68a via b. The cam protrusion pin 104b moves from the upper horizontal portion 68c to the lower horizontal portion 6

As is apparent from the above description, the disc changer of the present invention has a transport mechanism for transporting the disc-shaped recording medium inserted from the disc insertion opening and a disc-shaped recording medium transported. It has a recording / reproducing section for recording or reproducing an information signal, and a plurality of disc accommodating sections accommodating a plurality of disc-shaped recording media separately and arranged in a stack, and is movable in the arrangement direction of the plurality of disc accommodating sections. A stocker, a support chassis spaced apart from each other in the thickness direction of the disk-shaped recording medium to be conveyed, and a support chassis movably supported in a direction in which the disk-shaped recording medium stored in the stocker is brought into contact with the outer peripheral surface of the stocker. And a moving lever urged in a direction to approach the outer peripheral surface of the disk-shaped recording medium, and supported by one end of the moving lever. Characterized in that a possible abutting stopping part in contact with the outer peripheral surface of the housing disk-like recording medium to Tokka.

Therefore, since the movement of the disk-shaped recording medium in the direction of protruding from the disk housing portion is restricted by the abutting stop portion, it is possible to prevent the disk-shaped recording medium from falling off the disk housing portion.

Further, when the disc-shaped recording medium is conveyed, the moving lever is slidably brought into contact with the outer peripheral surface of the disc-shaped recording medium and moved in the directions in which they are separated from each other, which hinders the conveyance of the disc-shaped recording medium. Therefore, the transfer operation can be optimized.

According to a second aspect of the present invention, both end edges of the abutting stop portion in the arrangement direction of the disc storage portions are separated from the outer peripheral surface of the disc-shaped recording medium as they approach the both ends. Since the sloping guide part that displaces is formed, when the stocker is moved, the disc-shaped recording medium accommodated in the disc storage part is aligned by the abutting stop part, and the disc-shaped recording medium is properly and reliably removed from the disc storage part. Can be taken out.
