At the upper end of the clamp portion 66, a triangular plate-shaped contact plate portion 155 projecting toward the player 24 is provided horizontally. The contact plate 155 is connected to the player 24.
Of the upper slider 86, that is, the rectangular parallelepiped portion 124. Therefore, the spring 1
The rotation of the clamp part 66 urged by 54 is regulated.

A cylindrical projection 156 is provided on the upper surface of the contact plate 155, and is inserted into a rectangular hole 157 provided on the upper surface of the player 24.
6 is restricted within the range of the rectangular hole 157. When the clamp 66 is open, the protrusion 156 is located at the left end of the rectangular hole 157.

When the upper slider 86 moves backward,
As shown in FIG. 6, the protrusion 151 of the reproducing unit 65 moves in the chucking cam groove 152, and the reproducing unit 65 rotates counterclockwise. On the other hand, the movement of the upper slider 86 causes the rectangular parallelepiped portion 124 to escape from the contact plate portion 155 and is no longer regulated (also shown in FIG. 3), so that the clamp portion 66 is rotated clockwise by the urging force of the spring 154. As a result, the turntable 67 and the clamper 71 are put together, and the loaded disc 1 is held.
Thus, the movement of the upper slider 86 causes the disc 1 to move.
Is also performed.

Next, the operation of loading the 12 cm disk 1a and the 8 cm disk 1b to the reproduction position using the three levers 81 to 83 will be described.

As shown in FIG. 2, when the user designates the number of the disc 1, the player 24 moves in parallel with the magazine 23 and stops at the position corresponding to the designated disc 1. Then, the presence or absence of the disc 1 in the storage section corresponding to the number designated by the optical sensor 46 of the player 24 is detected.

When the disc 1 is not stored, the loading operation is not performed, and an indication to that effect is displayed on the liquid crystal panel of the apparatus main body. On the other hand, when the disc 1 is stored, the loading operation is started.

First, the case of loading the 12 cm disc 1a shown in FIG. 7 will be described.

As shown in FIG. 27, the first lever 81 rotates counterclockwise to move the 12 cm disc 1a into the magazine 2
3 and comes into contact with the roller 113 of the second lever 82. Here, as described with reference to FIG.

As shown in FIG. 28, after that, the second lever 82 starts to rotate, and the 12 cm
The disc 1a is a disc lower guide groove 32 of the magazine 23.
Moves down to the player 24 side and comes into contact with the roller 134 of the third lever 83.

At this time, as shown in FIG.
The upper portion of the disk 1a moves along the disk upper guide groove 47 formed on the lower surface of the sensor mounting portion 45. For example, when the movement of the disk 1a is guided only by the disk lower guide groove 32 of the magazine 23, the 12 cm disk 1a is tilted, and the disk surface may rub against the inner wall surface of the disk lower guide groove 32 and be damaged. Therefore, in the present application, by providing the disk upper guide groove 47, 12c
By guiding both the upper part and the lower part of the m disk 1a, it is possible to prevent inclination and prevent the board surface from being rubbed against the inner wall surface of the groove and damaged.

Further, by providing the disk upper guide groove 47 in the sensor mounting portion 45 of the optical sensor 46 (FIG. 5) for determining the presence or absence of a disk, the disk upper guide groove 47 can be formed without adding new parts. It can be provided at an optimal position.

Returning to FIG. 28, the 12 cm disc 1a moved to the player 24 side is once contacted with the roller 134 of the second lever 82 and received. Thereafter, the second lever 82 starts rotating clockwise. At this time, since the 12 cm disk 1a is pressed downward by the second lever 82, the third lever 83 with which the 12 cm disk 1a contacts is pressed downward.

Therefore, the projection 135 of the third lever 83 enters the lower first cam groove 143 as shown in FIG. The first cam groove 143 is provided corresponding to the 12 cm disk 1a, and the rotation angle of the third lever 83 becomes small.

Subsequently, as shown in FIG. 29, the third lever 83 starts rotating counterclockwise, and the 12 cm disc 1

(FIG. 6) sandwiches the 12 cm disk 1a.

Thereafter, the second lever 82 continues to rotate, separates from the 12 cm disk 1a, becomes substantially horizontal, and stops. Further, the third lever 83 rotates slightly clockwise and retracts from the 12 cm disk 1a. Further, the first lever 81 is completely horizontally inclined. In this state, the 12 cm disk is rotated by the turntable 67 to perform a reproducing operation. At this time, the stopper 1 provided on the first lever 82
Reference numeral 15 penetrates the square hole 119 and projects to the upper surface. As will be described later, the stopper 115 contacts the lower surface of the cover 57 (FIG. 1) to fix the player 24.

Next, the case of loading the 8 cm disc shown in FIG. 31 will be described. From this state, FIG.
As shown in FIG. 2, the first lever 81 rotates counterclockwise to push out the 8 cm disc 1b from the magazine 23. The extruded 8 cm disk 1b moves down the inclination of the disk lower guide groove 32 of the magazine 23 toward the player 24, gets over the roller 134 of the third lever 83, and enters the groove 84a of the loading groove 84.

At this time, the 8 cm disk 1b once comes into contact with the second lever 82, and further movement is restricted. At this time, the 8 cm disk 1b is held in the loading groove 84 and is not in contact with the third lever 83.
That is, no restricting force acts on the third lever 83.

Since the third lever 83 is urged in a counterclockwise direction, ie, a rising direction, by a spring or the like (not shown), the projection 135 enters the upper second cam groove 144 as shown in FIG. Will do. This second
The cam groove 144 is provided corresponding to the 8 cm disk 1b, and the rotation angle of the third lever 83 is larger than that when the 12cm disk 1a is used.

Subsequently, as shown in FIG. 33, the second lever 82 separates from the 8-cm disc 1b and starts rotating clockwise. Further, the third lever 83 rotates counterclockwise, and the 8 cm disk 1b is held in the disk holding grooves 131 and 132 before and after the third lever 83, and is conveyed upward.

When the center hole 162 of the 8-cm disc 1b coincides with the turntable 67 as shown in FIG. 34, the 8-cm disc 1b is sandwiched by the reproducing section 65 (FIG. 6) and the clamp section 66 (FIG. 6). You.

Thereafter, the second lever 82 continues to rotate as it is, becomes substantially horizontal, and stops. Further, the third lever 83 rotates clockwise and retracts from the 8 cm disk 1b. Further, the first lever 81 is completely horizontally inclined. In this state, the 8 cm disk is rotated by the turntable 67 to perform a reproducing operation. At this time, the stopper 115 provided on the first lever 82 penetrates the square hole 119 and projects to the upper surface. As will be described later, the stopper 115 is
The player 24 is fixed in contact with the lower surface of FIG.

As described above, in the loading operation, in the case of the 12 cm disc 1a, the second lever 82 is used.
Presses the 12 cm disc 1a toward the third lever 83, while the 8 cm disc 1b presses the second lever 8
2 prevents the 8 cm disc 1b from being pressed, thereby causing the cam grooves 143, 1 to rotate the third lever 83.
44 (FIG. 22) is switched. Therefore, disk 1
The loading operation is appropriately controlled according to the diameters of a and 1b.

Here, as shown in FIG.
The upper gear 61 provided at the upper part of the upper gear meshes with the upper rack part 59. In addition, the rotated second lever 82 (FIG. 1)
The stopper 115 provided in 9) has a sharp end at the tip thereof, and this is a square hole 119 provided on the upper surface of the player 24.
Through the teeth of the upper gear 61, and the rotation of the upper gear 61 is stopped. Further, as shown in FIG. 19, the stopper 1 provided on the second lever 82 (fixing means)
Fifteen pads 116 are pressed against the lower surface (fixed portion) of the cover 57.

By fixing the upper portion of the player 24 in this manner, the vibration transmitted to the player 24 during reproduction can be reduced, and the signal can be reproduced stably. In addition, a stopper 115 is provided by using a second lever 82 for loading the disc 1, and the stopper 115 is meshed with the upper gear 61, so that the player 24 during reproduction with a simple configuration can be reliably provided. Can be fixed.

On the other hand, the disc 1 held at the reproduction position
In the operation of unloading a and 1b into the magazine 23 (unloading operation), the operation of each of the levers 81 to 83 is reversed.

However, in this case, as shown in FIGS. 28 and 32, first, the disks 1a and 1b are held by the third lever 83 and descend. Then, the second counterclockwise rotation
Lever 82 pushes the disks 1a and 1b toward the magazine 23 side. The extruded disks 1a and 1b get over the rollers 134 of the third lever 83, and
The disc 3 is stored in the disc holding groove 25 by ascending the inclined surface of the disc lower guide groove 32.

Next, the means for taking out the disk 1 in the disk changer 20 will be described. As shown in FIGS. 36 and 37, the bottom plate 9 of the player 24 (FIG. 1)
In FIG. 37, a mounting portion 205 is erected close to the front side surface of a lower slider (moving body) 85, and a flat pressing lever 201 is rotatably mounted on the mounting portion 205, as shown in FIG. On the left side of the slider 85, a reinforcing rib 209 extends from the player 24 side. This rib 2
The first lever 81 described above is attached to the left side of 09.

As shown in FIG. 38, the pressing lever 201 is urged by a spring 202 in a counterclockwise direction, that is, in a falling direction. A contact portion 203 made of an elastic member such as rubber is attached to the upper end of the pressing lever 201. An arc-shaped protruding portion 2 is provided below the tip of the pressing lever 201.
The projections 204 are in contact with the bottom plate 96 of the player 24 when they are collapsed.

A sliding surface 2 for guiding the rotation is provided on the side surface of the lower slider 85 facing the pressing lever 201.
11 (also shown in FIG. 37) are protruded. Sliding surface 21
1 is a front horizontal portion 211a, an inclined portion 211b that is continuous with the horizontal portion 211a and rises toward the rear portion,
And a horizontal portion 211a which is continuous to the rear side and is set higher than the horizontal portion 211a.

On the surface of the pressing lever 201 which faces the lower slider 85, a columnar projection 212 (also shown in FIG. 37) is protruded, and this is in contact with the sliding contact surface 211. Note that the projection 2
12 is located on the front horizontal portion 211a.

Next, the position detecting means of the player 24 will be described. As shown in FIG. 35, a slit plate 22 in which grooves 221 are provided at regular intervals on the rear lower surface of the magazine 23
2 is fixed. Each groove 221 corresponds to each disk holding groove 25 for storing the disk 1.

On the other hand, as shown in FIG. 37, a U-shaped sensor 223 (also shown in FIG. 36) provided with a light emitter and a light receiver (not shown) is attached to the lower surface of the player 24. .

The sensor 223 is disposed so that the U-shaped portion sandwiches the slit plate 222, and detects light emitted from the light emitter and passing through the groove 221 with the light receiver on the opposite side, so that the player 24 It is detected that it is arranged at a position corresponding to the storage groove 25. Player 2
4 moves along the direction in which the discs 1 stored in the magazine 23 are arranged. In this case, the grooves 2 detected during the movement are moved.
By counting the number 21, it is possible to determine the position of the disc 1 in the magazine 23 where the player 24 is located. As shown in FIG. 35, the position detecting sensor 223 is arranged on the same line as the sensor 46 for determining the presence or absence of a disk.

Further, in FIG. 37, the mounting position of the pressing lever 201 with respect to the moving direction (the direction of the arrow) of the player 24 is a distance from the mounting position of the sensor 223 that is an integral multiple of the disc storage interval of the magazine 23, in this example, four pitches. It is set at a shifted position. This is because the sensor 223 for detecting the position of the player 24 is also used for detecting the position of the disk 1 to be removed, as described later.

The pressing lever 201 configured as described above
Will be described. In FIG. 2, the front panel (not shown) indicates the number of the disk 1 that the user wants to take out.
Specify with. Subsequently, the player 24 slides to the position of the disc 1 of the designated number.

As shown in FIG. 37, the player 24 is adjusted to a position shifted leftward by a distance corresponding to four discs in the storage interval of the specified disc 1. As a result, the pressing lever 201 coincides with the designated position of the disk 1. As described above, the sensor 223 used for detecting the position of the player 24 during loading is also used for positioning when the disc 1 is taken out, so that parts can be shared and cost can be reduced. it can.

Next, the lower slider 8 is moved from the state shown in FIG.
5 moves forward. Accordingly, the sliding contact surface 211 also moves forward as shown in FIG.
12 rises from the lower horizontal portion 211a along the inclined portion 211b and reaches the upper horizontal portion 211c. Thereby, the pressing lever 201 rotates clockwise against the urging force of the spring 202.

The rotated pressing lever 201 is connected to the magazine 23
Through the notch hole 33 to abut the outer edge of the disc 1,
This is pushed out to the medium outlet 214 side of the device. Thus, the user can take out the disc 1 from the magazine 23 by picking it out and pulling it out.

After the disk 1 is removed, the lower slider 85 starts moving backward. Therefore,
As shown in FIG. 38, the protrusion 212 of the pressing lever 201 descends from the upper horizontal portion 211c along the inclined portion 211b to reach the lower horizontal portion 211a. Thus, the pressing lever 201 is rotated counterclockwise by the biasing force of the spring 202 and falls down.

As described above, even when the storage interval of the discs 1 in the magazine 23 is narrow, the disc 1 is automatically pushed out by the pressing lever 201 after the player 24 moves to the target position of the disc 1. Unlike the pressing lever 19 (FIG. 43), there is no need for the user to perform the alignment by himself, and the disk 1 can be easily and reliably taken out.

The first lever 81 and the third lever 81
By using the lower slider 85 for rotating the lever 83 (FIG. 7) also for rotating the pressing lever 201, it is possible to reduce the number of parts and reduce costs.

After discriminating the presence or absence of the specified disc 1 by the optical sensor 46 in FIG. 35, the disc 1 may be pushed out only when the disc 1 is stored.

In this case, first, the player 24 is moved,
The optical sensor 46 is adjusted to the designated position of the disk 1. Here, the presence or absence of the disk 1 is determined, and the disk 1
When the disc 1 is not stored, the pressing lever 201 does not rotate, and an indication that the disc 1 is not stored is displayed on a panel or the like.

On the other hand, when it is detected that the disc 1 is stored, the player 24 moves rightward by a distance corresponding to four disc 1 storage intervals. As a result, the pressing lever 201 coincides with the designated position of the disc 1, and the pressing lever 201 rotates to push the disc 1.

When the specified disc 1 is not stored, the pressing lever 201 is not operated so that the user can immediately specify another disc 1.

Next, means for fixing the player 24 when the power of the disc changer 20 is turned off will be described. The fixing means of the player 24 includes an upper lock portion 261 shown in FIG. 40 and a lower lock portion 26 shown in FIG.

Since the chassis 26 is an internal component and is not visible from the outside and has no restrictions on its appearance, it is possible to freely select a material and a shape for increasing the strength. On the other hand, since the cabinet 50 is not involved in fixing the player 24, freedom in design can be ensured without being restricted by strength or the like.

When the power of the disc changer 20 is thereafter turned on, the lower slider 85 moves forward as shown in FIG. 48, and the lower lock portion 262 and the auxiliary lock portion 263 move forward to lock. The player 24 is released, and can move in the left-right direction.

As described above, in the disc changer 20, when the power of the apparatus is turned off, both the upper and lower portions of the player 24 are fixed to the main body. Failure is reliably prevented.

The locking and unlocking of the lock portions 261 to 263 are performed by operating the slider 8 for operating the levers 81 to 83 (FIG. 7) for loading.
The configuration can be simplified by adding the new components without using new components.

Further, in the present invention, when the power is turned off as shown in FIG. 40, the player 24 is moved to the rightmost home position. The home position of the player 24 corresponds to the end of the upper rack portion 59 and the lower rack portion (FIG. 45), and further movement is restricted. Player 2
The drive unit 43 on the right side of 4 is inscribed in the inner surface of the side plate of the cover 57, whereby the movement is restricted. Therefore, the home position at the right end is the most stable position for the player 24. By fixing the player 24 here, a failure such as dropping can be reliably prevented.

In this example, the position of the player 24 is regulated by bringing the player 24 into contact with the inner surface of the side plate of the cover 57. However, another regulating means is protruded from the chassis 26, and is brought into contact with the player 24. Position regulation may be performed. In this example, the home position is set at the right end, but may be at the left end.

Subsequently, the drop-off prevention cover (regulation plate) 3 shown in FIG. 50 of the disc changer 20 according to the present invention.
The rotation control means 5 will be described.

As described above, the fall-off prevention cover 35 is formed in a belt shape (FIG. 2) having a length equal to the entire width of the magazine 23, and is rotatably mounted. When the cover 34 is open, the cover 35 is positioned on the player 24 side to prevent the disc 1 from falling into the apparatus, and when the cover 34 is closed, the disc 1 is loaded on the player 24 side. Is retracted to the lid 34 side so as not to disturb.

The rotation control means of the fall-off prevention cover 35 includes a cover gear 3 formed on the shaft of the fall-off prevention cover 35.

The cover gear 321 is provided with the fall-off prevention cover 35.
The magazine 23 is rotatably mounted on the top of a support portion 326 erected substantially in a triangular shape at both ends of the magazine 23. The cover gear 321 meshes with the outer peripheral gear portion 327 of the double gear 322 described below.

The double gear 322 is for rotating the fall prevention cover 35. As shown in FIG. 51, a small-diameter inner peripheral gear portion 328 is integrally formed on one surface of a large-diameter outer peripheral gear portion 327. Things. A substantially elliptical bulging portion 331 is provided on a surface different from the surface on which the inner peripheral gear portion 328 is formed. One end of the bulged portion 331 includes the center of rotation of the double gear 322, and the other end has an elongated shape reaching the outer peripheral gear portion 327. Further, a hook 333 for hooking a spring 332 described later is provided at a position close to the bulging portion 331 and near the outer periphery.

As shown in FIG. 50, the double gear 322 is rotatably mounted on the side surface of the support portion 326. One end of a spring 332 is hooked on the hook 333, and the other end of the spring 332 is hooked on the upper surface of the chassis 26.

The slide plate 324 for rotating the double gear 322 is formed in a horizontally long substantially rectangular shape, and has three long holes 335 extending in the horizontal direction. Here, the support 3
26, three columnar projections 340 protruding from the side surface.
Is loosely fitted. As a result, the slide plate 324
It is slidable in the horizontal direction within the range of 35.

A rack 323 is formed on the upper right side of the slide plate 324, and meshes with the inner peripheral gear 323 of the double gear 322. Therefore, the slide plate 324
Moves, the double gear 322 rotates.

A contact portion 341 projects downward from the lower left side of the slide plate 324. A lower slider 85 is disposed below the slide plate 324, and a protrusion 342 is provided on a side surface of the lower slider 85 so as to project at substantially the same height as the contact portion 341. Therefore, the lower slider 8
When 5 moves, the protrusion 342 contacts the contact portion 341 and the slide plate 324 moves.

Since the double gear 322 is urged by the spring 332 as described above, the slide plate 324 meshing with the double gear 322 is urged rightward and is arranged at the rightmost position. At this time, the falling-off prevention cover 35 is disposed at a position on the lid 34 side by the cover gear 321 meshing with the double gear 322.

However, since the spring 332 does not apply an urging force to the double gear 322 in any direction when the direction of expansion and contraction is vertical, the slide plate 324 and the fall prevention cover 35 are held at that position. Will be done.

Next, the configuration of the control lever 325 will be described. As shown in FIG. 52, the control lever 325 is horizontally long, and is formed to be bent by approximately 45 ° near the shaft hole 343. A double gear 322 is provided at the lower end of the tip of the control lever 325.
A rack portion 344 meshing with (FIG. 50) is formed. A thick portion 345 formed thicker than other portions is formed at the center of the lower side.

The lower side of the thick portion 345 is formed with a sliding contact surface 346 which is a curved surface so as to swell downward toward the tip end. As will be described later, the swelling portion 331 (FIG. 51) of the double gear 322 slides on the sliding contact surface 346 to control the movement of the control lever 325.

On the back surface of the thick portion 345, first and second cam grooves 347 and 348 which are gently curved are formed in parallel. The first and second cam grooves 347 and 348 are integrated at the left end to form a wide groove 349.

As shown in FIG. 50, the control lever 325 is rotatably mounted on the lower part of the side surface of the lid 34, and moves in conjunction with opening and closing of the lid 34. Further, the sliding contact surface 346 comes into contact with the bulging portion 331 of the double gear 322, and the control lever 32
5 are arranged diagonally. Further, when the lid 34 is closed, as shown in FIGS. 56 and 59, a guide projection 351 projecting from the left side of the side surface of the support portion 326 is located in the wide groove 349.

As shown in FIG. 53, the cover gear 321 meshes with only half of the double gear 322 when viewed from the top, and the control lever 325 is disposed in parallel and close to the cover gear 321. You. When the control lever 325 moves, the rack 344 of the control lever 325 meshes with the other half of the double gear 322.

The falling-off prevention cover 3 configured as described above
The operation of the rotation control of No. 5 will be described.

As shown in FIG. 54, when the power of the apparatus is turned on, the double gear 322 is supported at a position where the direction of expansion and contraction is vertical by the urging force of the spring 332. At this time, the slide plate 324 is arranged at the rightmost position, and the fall prevention cover 35 is arranged on the lid 34 side. Therefore, loading of the disc 1 onto the player 24 is not hindered.

When the power of the apparatus is turned off, the player 24
Moves to the home position. As a result, the projection 342 of the lower slider 85 is brought into contact with the contact portion 34 of the slide plate 324.
1 is arranged at a position corresponding to 1.

Next, as shown in FIG.
5 moves to the left. As a result, the protrusion 342 presses the contact portion 341 to move the slide plate 324 to the left. This causes the double gear 322 to rotate clockwise,
The cover gear 321 rotates counterclockwise. Therefore, the fall prevention cover 35 is disposed on the player 24 side.

By disposing the fall-off prevention cover 35 on the player 24 side, even if the disc 1 attempts to move in the direction of falling off from the magazine 23, the disc 1 comes into contact with the fall-off prevention cover 35 and falls into the apparatus. Is prevented.

Next, the operation of the fall prevention cover 35 and the control lever 325 when the cover 34 is opened while the power of the apparatus is on will be described. When the power is on and the lid 34 is closed, as shown in FIG.
5 is arranged on the lid 34 side.

Therefore, in order to allow the disk 1 to be stored when the lid 34 is opened,
5 needs to be retracted to the player 24 side. here,
Although it is conceivable to move the slide plate 324 by the lower slider 85 to rotate the fall-off prevention cover 35, when the power is on as shown in FIG.
4 does not remain in a fixed position, so that the lower slider 85 attached to the player 24 cannot be used.

Therefore, as shown in FIG.
Is used to rotate the lid 34. Before the lid 34 is opened, the sliding surface 346 of the control lever 325 is
Is in contact with the bulging portion 331 of the helical member. At this time, double gear 3
Due to the direction of 22, the bulging portion 331 is tilted to the left, and the control lever 325 is at a lower position than in FIG. 59 when the power is off.

When the lid 34 is opened from this state as shown in FIG. 57, the sliding contact surface 346 comes into sliding contact with the bulging portion 331,
The control lever 325 is pulled by the lid 34 and moves diagonally right and downward. Since the control lever 325 moves while being lowered, the guide protrusion 351 of the support portion 326 enters the first cam groove 347 on the upper side.

Then, as shown in FIG.
1 moves along the first cam groove 347 and reaches its end. At this time, the control lever 325 moves (first
), The rack portion 344 meshes with the outer peripheral gear portion 327 of the double gear 322, and rotates the double gear 322 clockwise. Therefore, the fall prevention cover 35 rotates counterclockwise and moves to the player 24 side. Thus, when the lid 34 is opened, the fall prevention cover 35 has moved to the player 24 side, and the user can put the disc 1 in and out of the magazine 23.

Next, the operation of the fall prevention cover 35 and the control lever 325 when the lid 34 is opened when the power of the apparatus is off will be described. When the power is off and the lid 34 is closed, as shown in FIG.
5 is arranged on the player 24 side.

Therefore, it is no longer necessary to retract the fall-off prevention cover 35 when the lid 34 is opened, and the disc 1 can be taken in and out of the magazine 23 by opening the lid 34. That is, it is necessary to prevent the control lever 325 linked to the lid 34 from acting on the falling-off prevention cover 35.

When the power is turned off, the slider 85 moves to the left to rotate the cover gear 321 counterclockwise in order to fix the player 24 to the main body as described above. Before opening, double gear 322
Is slightly rotated clockwise from the state in which the power is on (FIG. 56), and the bulging portion 331 is arranged more upward. The sliding contact surface 346 of the control lever 325 is in contact with the periphery of the top portion 331a of the bulging portion 331,
The control lever 325 is located at a position higher than the state shown in FIG.

When the lid 34 is opened from this state as shown in FIG. 60, the control lever 325 is pulled by the lid 34 while sliding on the swelling portion 331 and moves diagonally downward and to the right. I do. Since the control lever 325 moves while being raised, the guide protrusion 351 of the support portion 326 enters the lower second cam groove 348.

Then, as shown in FIG.
1 moves along the second cam groove 348 to reach its end. At this time, the control lever 325 moves above the first path, that is, the second path, and the rack portion 344 passes without meshing with the outer peripheral gear portion 344 of the double gear 322. Therefore, the fall prevention cover 35 does not rotate.

Thus, when the cover 34 is completely opened, the fall-off prevention cover 35 is located on the player 24 side, and the user can put the disc 1 in and out of the magazine 23.

As described above, since the disc changer 20 uses the control lever 325 to rotate the fall-off prevention cover 35, a dedicated motor is not required unlike the related art, and the cost is reduced. be able to.
In addition, since there is no need for a means for detecting the open / closed state of the lid 34 and a control means for supplying power or the like corresponding thereto,
The configuration can be simplified.

The lower slider 85 shown in FIG. 50 not only rotates the drop-off prevention cover 35 but also loads the first and third levers 81 and 83 for loading the disc 1.
(FIG. 7), a pressing lever 201 (FIG. 37) for pushing out the disc 1 to the take-out side, a lower lock portion 262 (FIG. 45) for fixing the player 24 at the home position, and a slide plate for rotating the fall prevention cover 35. 324 (FIG. 5)
5) is also used to control. Therefore, by using these driving means by one lower slider 85, the timing of each operation can be accurately controlled, and the cost can be reduced by reducing the number of parts.

It should be noted that, as shown in FIG.
When rotating 01, the lower slider 85 is moved forward. On the other hand, the first lever 81 shown in FIGS.
When the third lever 83 shown in FIGS. 23 to 26 is operated, the lower lock portion 262 shown in FIG. 49 is locked, and when the slide plate 324 shown in FIG. 55 is moved, the lower slider 85 is moved backward. Let it. As described above, various operations can be selected according to the moving direction of the lower slider 85.

Although the present invention has been described with reference to a case where the present invention is applied to a disc changer for CDs, the present invention is not limited to this, and may reproduce other disc-shaped recording media. Further, in the present application, the disc changer having only the reproducing means has been described, but the disc changer may also have the recording means.

[0198]

As described above, the present invention has a lever for pushing out the disk stored in the storage means, a regulating plate for preventing the stored disk from dropping off, and a fixing means for the reproducing means. These operations are controlled by a single moving body.

Therefore, according to the present invention, since the moving body is also used as a means for operating the lever for pushing out the disk, the regulating plate, and the means for fixing the reproducing means, the components can be used in common. Cost can be reduced by simplification and reduction of the number of parts. Also, by using this moving body for the operation of the disk transport means,
There are effects that the timing of each operation can be accurately controlled and that the cost can be further reduced.
