As shown in FIG. 1 and FIG. 2, the disc reproducing unit 32A and the disc housing unit 33A are in an opposed arrangement relationship, and both can rotate (swing) and can be inclined. Therefore, the angle α at which the disk reproducing unit 32A must rotate is smaller than the angle at which the disk reproducing unit must rotate when the disk housing unit is fixed, and is ± 3 degrees with respect to the horizontal position. Sufficiently, the space 81A required for the disk reproducing unit 32 to rotate is small. Similarly, the angle β at which the disk storage unit 33A must rotate is smaller than the angle at which the disk playback unit is fixed and only the disk storage unit must rotate, and ± 3 degrees with respect to the horizontal position is sufficient. The space 82A required for the rotation of the disk housing unit 33A is small. Moreover, the space 81A
And the space 82A overlap in the Z direction. Therefore, the height of the disc reproducing device 30A is H10, and it is thin.

Also, since both the disk reproducing unit 32A and the disk accommodating unit 33A rotate, the disk transport path 48A of the disk reproducing unit 32A and the predetermined disk accommodating portion of the disk accommodating unit 33A are aligned. The time required to perform the above operation is shorter than that of a disk reproducing apparatus in which only the disk reproducing unit operates. Thus, the time required from issuing a command to completing the operation according to the command is short.

2. [Schematic Operation of Disc Reproducing Apparatus 30A] (FIGS. 4 to 9) Next, the operation of the disc reproducing apparatus 30A having the above configuration will be schematically described.

Then, the operation of transporting the disk 11 in the disk storage unit 33A to the disk reproduction unit 32A and reproducing the disk 11 is started.

(2) The disk 11 whose reproduction has been completed is transferred to the original disk storage section 41A of the disk storage unit 33A.
Operation to return to −5 (FIG. 5): The disk 11 that has been reproduced up to that time is a disk pulled out from the second disk accommodating portion 41A-2, and the disk reproducing unit 32A and the disk accommodating unit 33 are (A), FIG.
As shown in (A), the disc transport path 48A of the disc reproducing unit 32A and the second disc accommodating portion 41A
-2 are aligned.

When the computer instructs to play another disk, the operation shown in FIG. 5 is performed. As shown in FIG. 5B, the disk transport mechanism 34A
Operates to hold the disk 11, then the turntable 37A moves down, the clamper 38A moves up, and the clamp of the disk 11 is released.

Subsequently, as shown in FIG. 5C, the disk transport mechanism 34A transports the disk 11 in the Y1 direction and stores it in the second disk storage section 41A-2.
Finally, as shown in FIG.
1a hits the periphery of the disk 11 and holds the disk 11.

The disc reproducing apparatus 30A normally repeats the above operation. The disc playback device 30A performs the following operation in addition to the above operation, according to an operation of the operator. (3) Operation for reproducing a disk inserted from outside the disk reproducing device 30A (FIG. 6): When the operator instructs to reproduce the disk to be inserted, the operation shown in FIG. 6 is performed.

The both-side rotating mechanism 35A operates, and both the disk reproducing unit 32A and the disk accommodating unit 33A are rotated, and as shown in FIGS. 16A and 6A, the disk reproducing unit 32A The disk transport path 48A and the empty disk storage part, for example, the second disk storage part 41A-2 are aligned.

When the disk 11 is pulled out, the flap 112 is returned to the original state, and the disk insertion slot 71A is closed. Here, the flap 112 cannot be closed unless the operator pulls out the disk 11. That is, when a command to close the flap 112 is issued,
The disc insertion detection switch 160 (see FIG. 28), which will be described later, is turned on for a predetermined time, and the disc insertion detection switch 1 is turned on.
If 60 is off (the disk 11 is not pulled out), the instruction to close the flap 112 is not executed. Therefore, the inconvenience that the flap 112 hits the disk 11 does not occur.

(5) Operation for accommodating a disk outside the disk reproducing device 30 in the disk accommodating unit 33 (FIG. 8): an operator instructs an accommodating operation, and an accommodating section for accommodating the disk, for example, Disk storage part 41 of 3
When A-3 is designated, the operation shown in FIG. 8 is performed.

The both-side rotating mechanism 35A operates to rotate both the disk reproducing unit 32A and the disk accommodating unit 33A, and as shown in FIGS. 16B and 8A, the disk reproducing unit 32A The disc transport path 48A and the third disc accommodating portion 41A-3 are aligned. Next, the flap 112 in FIG. 14 is rotated to open the disc insertion opening 71A.

Next, the operator inserts the disc 11 through the disc insertion slot 71A. When the disk 11 is inserted from the disk insertion slot 71A, the disk transport mechanism 34A holds the inserted disk 11 as shown in FIG. 8B. Subsequently, as shown in FIG. 8C, the disk 11 held by the disk transport mechanism 34A is transported in the Y1 direction. The disk transport mechanism 34A transports the disk 11 through the disk transport path 48A of the disk playback unit 32A in the direction of the third disk storage section 41A-3 of the disk storage unit 33A. Also, flap 11
2 is returned to the original state, and the disc insertion slot 71A is closed.

Finally, as shown in FIG. 8D, the pressing finger 131a pushes the peripheral edge of the disk 11 to house the disk 11 in the third disk housing 41A-3 and hold the disk 11. . At this time, the disk transport mechanism 34A and the disk 11 are separated.

(6) Operation for Ejecting the Disk in the Disk Housing Unit 33 to Outside the Disk Playback Device 30 (FIG. 9): When the operator instructs the ejection operation and specifies the fourth disk housing part 41A-4. The operation shown in FIG. 23 is performed.

The both-side rotating mechanism 35A operates, and both the disk reproducing unit 32A and the disk housing unit 33A are rotated, and as shown in FIGS. 16C and 9A, the disk reproducing unit 32A The disc transport path 48A and the fourth disc accommodating portion 41A-4 are aligned.

And pull it out of the disc player 30A.

As can be seen from the above description, the disc reproducing apparatus 30A has the following features. (1) The height dimension is H10, and it can be made thin. For the following reasons.

As shown in FIG. 2, the disc reproducing unit 32A and the disc accommodating unit 33A are in a facing relationship, and both can rotate and tilt. For this reason, the angle α at which the disk reproducing unit 32A must rotate is smaller than the angle at which the disk reproducing unit must rotate when the disk housing unit is fixed. Therefore, the space 81A required for the rotation of the disk reproducing unit 32A is small. The angle α is about 6 degrees.

The angle β at which the disk storage unit 33A must rotate is smaller than the angle at which the disk playback unit is fixed and only the disk storage unit must rotate. Therefore, the space 82A required for the rotation of the disk housing unit 33A is small. The angle β is about 6 degrees.

The space 81A required for the disk playback unit 32A to rotate and the space 82A required for the disk storage unit 33A to rotate are:
Most of them overlap in the Z direction. (2) The distance g1 between adjacent disks 11 housed in the disk housing portions 41A-1 to 41A-6 of the disk housing unit 33A does not become narrow.

Disk storage units 41A-1 to 41A-6
Are arranged in parallel with each other. (3) It is possible to shorten the time required from completion of a command to completion of an operation corresponding to the command.

Since both the disk reproducing unit 32A and the disk accommodating unit 33A rotate, the disk transport path 48A of the disk reproducing unit 32A and a predetermined disk accommodating portion of the disk accommodating unit 33A are aligned in a straight line. This is because it is possible to shorten the time required for this.

Next, the configuration of each section of the disc reproducing apparatus 30A will be described. 3. [Configuration and Operation of Disk Transport Mechanism 34A] (FIG. 1)

Are separated. As a result, the disk selecting means becomes operable.

[0113] 5. [Drive mechanism assembly 110A] (FIG. 35)
To 41) The drive mechanism assembly 110A of FIG.
Is not one but two (link arm 1
83A pins 183Aa, 183Ab), and in the first half, the pins 183Aa engage with the cam gear 177A,
In the latter half, the pin 183Ab is engaged with the cam gear 177A instead of the pin 183Aa.
The pin 183Aa and the pin 183Ab share the relationship. Therefore, the engagement between the pin 183Aa and the pin 183Ab and the cam gear 177A is performed exclusively at a position close to the outer periphery of the cam gear 177A, so that unnecessary strong force is not applied to the pins 183Aa and 183Ab. Reliability is improved by always performing the test under the same conditions.

The drive mechanism assembly 110A is configured such that the stepped groove 105Ad of the slide member 105A applies a force to rotate the link arm 183A. As shown in FIG. 36B, the slide member 105
Stepped groove 10 formed in horizontal plate portion 105a of A
5Ad extends in the Y1 and Y2 directions as a whole,
It is a combination of a Y-direction groove extending in the Y1 direction and an oblique groove extending in the Y1 direction while being deviated in the X1 direction. The first groove extends in the Y1 direction from the Y2 side.

The radial groove 177Aa-4 and the arc-shaped groove 177Aa-1 are arranged in this order.

The pin 183Aa of the link arm 183A
Passes through a step-shaped groove 105Ad of the slide member 105A, and a lower end thereof is formed in a central concave portion 177Aa of the cam gear 177A.

Has a lower end formed at the center recess 177A of the cam gear 177A.
a-2, for example, located in the central recess 177Aa-2 of the cam gear 177A.

Of the step-like grooves 105Ad of the slide member 105A, the second Y-direction groove 105Ad-3,
The third Y direction groove 105Ad-5 is
It functions to regulate the position of the pin 183Aa so that the 3A does not rotate. First oblique groove portion 105Ad-2 and second oblique groove portion 105Ad-2
The oblique groove 105Ad-4 functions to move the pin 183Aa in the direction in which the link arm 183A rotates.

The arc-shaped groove 177Aa- of the cam gear 177A
1 regulates the position of the pin 183Aa or 183Ab,
The link arm 183A is prevented from rotating. First,
The second radial grooves 177Aa-3 and 177Aa-4 release the position regulation of the pins 183Aa and 183Ab, which have been located and restricted in the arc-shaped groove 177Aa-1, respectively, by releasing the pins 183Aa and 183Ab. Is the cam gear 17
7A so as to be movable in a substantially radial direction. Also,
First and second radial grooves 177Aa-3, 177Aa-4
Prevents the cam gear 177A from rotating when the pins 183Aa and 183Ab are fitted therein. When the cam gear 177A rotates clockwise, the second radial wall portion 177Aa-7 hits the pin 183Ab and stops the rotation of the cam gear 177A. First radial wall portion 17
7Aa-6 hits the pin 183Aa when the cam gear 177A rotates counterclockwise,
The rotation of A is stopped.

Therefore, the cam gear 177A, the slide member 105A and the pinion 173 are in a state where the slide member 105A cannot slide (the pinion 173A cannot rotate) when the cam gear 177A is rotatable.
Conversely, when the cam gear 177A cannot rotate,
The slide member 105A is slidable (the pinion 173A is rotatable).

Is engaged with the rack 140d of the loading arm 140, and when the gear 179 rotates, the loading arm 140 is rotated.

The gear 179 constitutes a driving member for a recording medium conveying means in the claims. The pinion 173 constitutes a turntable vertical movement mechanism driving member in the claims. The selection transmission mechanism 250A includes a loading motor 174 and a gear 1 from the drive mechanism assembly 110A shown in FIG.
79 and the pinion 173 are removed, and the remaining parts, namely, the slide member 105A, the shaft 170, and the gear 171

The slide member 105A is connected to the horizontal plate portion 10
5a, a vertical plate portion 105b, and an L-shaped arm portion 105Af extending in the Y2 direction from the vertical plate portion 105b. The mountain-shaped guide groove 105c is formed in the vertical plate portion 105b as described above. In the horizontal plate portion 105b,
A step-like groove 105Ad is formed. A rack 105e is formed on the horizontal plate portion 105a. The rack 105e is engaged with the pinion 173.

Next, the operation of the driving mechanism assembly 110A having the above configuration will be described. The drive mechanism assembly 110A is shown in FIG. 37 (A), (B), (C), FIG.
(B), (C), FIG. 39 (A), (B), (C), FIG.
It operates while changing in the order of 8.

FIGS. 41A to 41H show the operation of each part constituting the drive mechanism assembly 110A. The selection transmission mechanism 250A makes the first selection transmission state between FIG. 37 (A) → FIG. 37 (B), and the second selection transmission state between FIG. 37 (B) → FIG. 38 (B). Make, Fig. 38 (B) → Fig. 38
During (C), the first selection transmission state is made again, and FIG.
From (C) to FIG. 39 (C), the second selection transmission state is made again, and from FIG. 39 (C) to FIG. 40, the first selection transmission state is made again.

As shown in FIGS. 36B and 41C, when the slide member 105A slides in the Y2 direction,
The pin 183Aa moves relative to the slide member 105A in the order of I → II →... → VI → VII.
When the slide member 105A slides back in the Y1 direction, the pins 183Aa relatively move in the reverse order.

As shown in FIGS. 36 (A) and 41 (A), when the cam gear 177A rotates clockwise,
The pins 183Aa move relative to the cam gear 177A in the order of 1 → 2 →... → 6 → 7. Another pin 1
As shown in FIGS. 36 (A) and 41 (B), 83Ab is relatively positioned relative to cam gear 177A in the order of 1 → 2 →.
Move like 6 → 7. When the cam gear 177A rotates counterclockwise and returns, the pins 183Aa, 183A
b moves relatively in the reverse order.

The following description is made with reference to FIGS. 36 (A) and (B) and FIGS. 41 (A) to (H). It should be noted that, for convenience of description, there is no special description for the drawings to be referred to. When the disk transport mechanism 34A is in the initial state shown in FIG. 18, the drive mechanism assembly 110A is in the state shown in FIG.

The cam gear 177A is rotating counterclockwise, the pin 183Aa is at the position 1 in the arc-shaped groove 177Aa-1, the link arm 183A is rotating counterclockwise, and the pin 183Ab is at the center. 177Aa-
It is in position 1 in 2. Therefore, the cam gear 177A is in a state capable of rotating clockwise. On the other hand, the slide member 10
5A is at position V1 and pin 183Aa is
The first diagonal groove 105A of the direction groove 105Ad-1
It is at the position I at the time of d-2. When the pin 183Aa is restricted by the arc-shaped groove 177Aa-1 of the cam gear 177A, the link arm 183A is in a state where it cannot rotate, and the pin 183Aa is located at the position I at the end of the first Y-direction groove portion 105Ad-1. Therefore, the sliding member 105A
It cannot slide in two directions. Therefore, pinion 1
73 is in a state where it cannot rotate. Therefore, the selection transmission mechanism 250A is in the first selection transmission state.

The pin 104 has a mountain-shaped guide groove 105.
c is guided by the skirt portion 105c-1 on the Y2 side. The drive mechanism assembly 110A changes from the state shown in FIG. 37 (A) to the state shown in FIG. 37 (B).

When the motor 174 starts and rotates forward, the rotation of the motor 174 is transmitted to the gear 186 via the worm 175, gear 171, gear 181, and gear 172, and the gear 186 rotates counterclockwise. The counterclockwise rotation of the gear 186 is transmitted to the cam gear 177A, and the cam gear 1
77A rotates clockwise. When the cam gear 177A rotates clockwise, the pin 183Aa relatively moves from the position 1 in the arc-shaped groove 177Aa-1 toward the position 2. Until the pin 183Aa reaches the position 2, the link arm 183A remains at the original position, and the pin 183Ab is still at the position I in the step groove 105Ad.
The slide member 105A cannot slide in the Y2 direction, and the pinion 173 cannot rotate.

The gear 186 is rotated by the above-described counterclockwise rotation of the gear 186, and the loading arm 140 is rotated.
Is rotated in the L1 direction, and as described above, the disc transport mechanism 34A moves the disc 11 from the inside of the disc accommodating portion 41A-1 in the Y2 direction to the position shown in FIG.
-6 is detected).

The pins 183Aa are relatively arc-shaped grooves 177.
Reaching position 2 at the end of Aa-1, arc-shaped groove 177Aa-
1 of the cam gear 177A.
Can no longer rotate. Therefore, the operation of the disk transport mechanism 34A stops. When the pin 183Aa reaches the position 2 at the end of the arc-shaped groove 177Aa-1,
The pin 3Aa faces the first radial groove 177Aa-3, and the pin 183Aa is released from the regulation by the arcuate groove 177Aa-1 so that the pin 183Aa can move toward the center of the cam gear 177A. Therefore, the slide member 105A can be slid in the Y2 direction. That is, the cam gear 177A cannot rotate, and the slide member 105A can slide. Therefore, the selection transmission mechanism 250A changes from the first selection transmission state to the second selection transmission state. The pin 183
Ab moves from position 1 to position 2 in the central recess 177Aa-2.

When the drive mechanism assembly 110A is in the state shown in FIG. 37B, the cam gear 177A cannot rotate, and the slide member 105A can slide (pinion 173 can rotate). Is gear 172
, While revolving around itself, the pinion 173 is rotated. The rotation of the pinion 173 causes the slide member 105A to move in the Y2 direction at the position V shown in FIG.
2 and the pin 183Aa is relatively moved from the position II →
Moving to position IV via III, drive mechanism assembly 110A is moved in three stages, i.e., FIG.
After passing through the state of FIG. 7C and the state of FIG.
The state shown in FIG.

More specifically, first, the drive mechanism assembly 110A
Changes from the state shown in FIG. 37 (B) to the state shown in FIG. 37 (C). As a first stage, the slide member 105A slides in the Y2 direction from the state shown in FIG.
Aa moves relatively from position I to II in the first oblique groove portion 105Ad-2, and thus the link arm 183A is rotated clockwise. The rotation of the link arm 183A causes the pin 183Aa to move in the first radial groove 177Aa-3 relative to the position 2 → 3 with respect to the cam gear 177A, and the pin 183Ab to move the central recess 177Aa-.
The position inside 2 moves from position 2 to position 3, and the state shown in FIG.

Next, the drive mechanism assembly 110A is
The state shown in FIG. 38A is changed from the state shown in FIG. In the second stage, the slide member 105A further
The pin 183Aa slides in two directions and the second Y-direction groove 1
05Ad-3 relatively reaches position II → III (for the cam gear 177A, the pin 183Aa and the pin 1
83Ab does not move), and the state shown in FIG. The rotation of the cam gear 177A is restricted by the pin 183Aa being located in the first radial groove 177Aa-3.

Next, the drive mechanism assembly 110A is
The state shown in FIG. 8A is changed to the state shown in FIG. In the third stage, the slide member 105A is further moved to Y
The pin 183Aa slides slightly in two directions, and the pin 183Aa relatively moves from the second Y-direction groove 105Ad-3 to the second oblique groove 105A.
d-4, and moves from position III to IV, so
The link arm 183A is rotated clockwise. The rotation of the link arm 183A causes the pin 183Aa to move from position 3 to position 4 with respect to the cam gear 177A,
3Ab moves from position 3 to position 4, and the state shown in FIG. Pins 183Aa, 183Ab and cam gear 177
Looking at the relationship with A, the pin 183Aa has come out of the first radial groove 177Aa-3, and the pin 183Ab has been pressed against the inner peripheral wall 177Aa-5.

Since the pin 183Ab is pressed against the inner peripheral wall 177Aa-5 and the link arm 183A cannot rotate further clockwise, the slide member 105
A slides to the position V2, the second oblique groove 1
Pin 183A located at position IV in 05Ad-4
Due to a, further sliding in the Y2 direction becomes impossible.

On the other hand, the pin 183Aa is connected to the first radial groove 1
77Aa-3, the cam gear 1
77A can be rotated clockwise. Therefore, the selection transmission mechanism 250A changes from the second selection transmission state to the first selection transmission state again. When the slide member 105A slides to the position V2, the pin 104 is guided by the top portion 105c-2 of the mountain-shaped guide groove 105c, and the disc reproducing unit 32A rotates in the J direction and turns. The table 37A moves up and the disk 1
1 is clamped.

Next, the drive mechanism assembly 110A is
The state changes from the state shown in (B) to the state shown in FIG. The selection transmission mechanism 250A changes from the second selection transmission state to the first selection transmission state again, the gear 186 rotates counterclockwise, the gear 179 rotates, and the loading arm 140 rotates in the L1 direction. When the loading arm 140 slightly rotates (when the cam gear 177A slightly rotates clockwise, the pin 183Ab relatively moves and reaches a substantially intermediate position between the position 4 and the position 5).
Then, the slit 140g-6 is detected, and usually, the motor 174 is stopped. The drive mechanism assembly 110A is shown in FIG.
The operation is stopped in a state between the state shown in FIG. 8B and the state shown in FIG.

With the slight rotation of the loading arm 140, the disk transport mechanism 34A slightly operates,
The I-shaped rollers 61A and 62A
Separate from a. In addition, another motor, a turntable rotation motor (not shown), is started and the disk 11 is rotated.
Rotates to perform playback.

When the disk 11 is to be stored in the original disk storage portion 41A-1 after the completion of the disk reproduction, the motor 174 rotates in the reverse direction, and the gear 186 first rotates clockwise.
The cam gear 177A rotates counterclockwise, the I-shaped rollers 61A and 62A hold the disk 11, and the slide member 105A slides in the Y1 direction to release the clamp of the disk 11, and the cam gear 177 again. --- The disk 11 which has been rotated clockwise and the clamped
Conveyed in the direction.

When ejecting the disc, the slit 1
Even if 40g-6 is detected, the motor 174 continues to rotate forward without being stopped, and the cam gear 177A rotates clockwise until the second radial wall portion 177Aa-7 hits the pin 183Ab. The drive mechanism assembly 110A is shown in FIG.
The state shown in FIG.

When the cam gear 177A rotates, the gear 179 rotates via the gear 186, and the loading arm 140 moves in the L1 direction into the slit 140g-4.
Is rotated to the position where is detected, and the disk transport mechanism 34A grips the peripheral edge of the disk 11 as described above.

The cam gear 177A rotates clockwise until the second radial wall portion 177Aa-7 hits the pin 183Ab, and the drive mechanism assembly 110A is in the state shown in FIG. 38 (C). When the second radial wall portion 177Aa-7 hits the pin 183Ab, the cam gear 177A cannot rotate any more. Therefore, the operation of the disk transport mechanism 34A stops. When the pin 183Ab reaches the second radial wall portion 177Aa-7, the pin 183Ab faces the second radial groove 177Aa-4, and the pin 183Ab restricts the regulation by the inner peripheral wall 177Aa-5. The cam gear 177A is released and can move in the outer circumferential direction. Therefore,
The slide member 105A can be slid in the Y2 direction. That is, the cam gear 177A cannot rotate, and the slide member 105A can slide. Therefore, the selection transmission mechanism 250A changes from the first selection transmission state to the second selection transmission state again. The pin 183Aa moves from the position 4 to the position 5 in the central recess 177Aa-2.

Next, the drive mechanism assembly 110A is
The state shown in FIG. 39C changes to the state shown in FIG. The slide member 105A starts sliding in the Y2 direction again, and the pin 183Aa relatively moves from the position IV to the position V in the second oblique groove portion 105Ad-4, so that the link arm 183A is rotated clockwise.

The pin 104 has a Y-shape in the mountain-shaped guide groove 105c.
The disc playback unit 32A is rotated in the J direction by being guided by the foot portion 105c-3 on the first side,
The turntable 37A moves down, and the clamp of the disk 11 is released. As described above, both the upward movement and the downward movement of the turntable 37A are performed with the motor 174 kept rotating forward, that is, without the motor 174 rotating backward.

The drive mechanism assembly 110A is shown in FIG.
From the state shown in FIG. 40 to the state shown in FIG. When the selection transmission mechanism 250A changes from the second selection transmission state to the first selection transmission state again, the cam gear 177A rotates clockwise, and rotates to the position shown in FIG.
The rotation of the cam gear 177A causes the gear 186 to rotate.

1c and one pin 191d on the opposite side. The clamper 38A has an annular groove 38Ac having a central hole 1.
91a and supported by the clamper holder 191. The width w1 of the annular groove 38Ac in the Z direction and the thickness t1 of the clamper holder 191 have a relationship of w1> t1. The clamper 38A has a play of a dimension (w1-t1) with respect to the clamper holder 191 in the axial direction of the clamper 38A.

The clamper holder 191 has pins 191b,
191c and 191d are connected to the opening 1 at the center of the chassis 103.
03d guide groove 103d formed at the edge of 03a,
It can move in the Z1 and Z2 directions by fitting with 103e and 103f. The clamper 38A protrudes toward the lower surface of the chassis 103 through the opening 103a.

The clamp slider 192 has a bifurcated fork portion 192a on one end side.
a has diagonal cam grooves 192b, 192c, and 192d, and has a pin portion 192e on the other end side. The clamp slider 192 has oblique cam grooves 192b, 192c, 19
2d is provided on the chassis 103 so as to be slidable in the A3 and A4 directions with the pins 2b fitted to the pins 191b, 191c and 191d, respectively. The A3 direction is a direction between Y1 and X2, and the A4 direction is a direction between Y2 and X1. The pin portion 192e faces the mountain-shaped cam 140f of the loading arm 140.

The clamp slider 192 is urged in the A4 direction by a tension coil spring 193. The mountain-shaped cam 140f has slope portions 140f-1, 14f on both sides.
0f-2 and the top surface 140f-2. The oblique cam groove 192b has an upper portion 192b-1 and an oblique portion 192b.
-2 and a lower portion 192b-3.

The cam 140f causes the clamp slider 192 to move in three directions P10 and P1 in the directions A3 and A4.
1, P12. Thus, the clamper holder 191 is positioned at a high position (retraction support position) Hu, an intermediate position (intermediate support position) Hm, and a low position (rotatable support position) Hl (FIG. 17 (G)). .
The high position Hu is such that the clamper holder 191
This is a retreat support position that supports the clamp 8Ab and supports the clamper 38A at a retreat position H10 that is higher than the disc 11 and does not hinder the conveyance of the disc 11. The intermediate position Hm is a position where the clamper 38A is supported at a height position H11 in contact with the disk 11. The lower position Hl is
Flange part 38 of clamper 38A at height position H11
Ab is a position lower than Ab, that is, a position where the clamper holder 191 is separated from the flange portion 38Ab.

Next, the operation of the disc clamp mechanism 190 will be described. FIG. 17G shows the clamper holder 19.
FIG. 17 (I) shows the turntable 37A.
The movement of is shown. First, the operation of clamping the disk 11 will be described.

When the disk transport mechanism 34A is in the initial state shown in FIG. 32, as shown in FIG. 44A, the clamp slider 192 is located at the position P10, and the clamper holder 191 is located at the high position Hu. , Clamper 38
A is located at the high position H10, and the turntable 3
7A is located at a low position (retraction position) H20 which does not hinder the conveyance of the disk 11 (FIG. 17 (I)).

The loading arm 140 is rotated counterclockwise by the forward rotating motor 174, and
Is transported to the reproduction position, as shown in FIG. That is, the slope 140f-
1 presses the pin portion 192e, the clamp slider 192 slides in the A3 direction against the spring 193 to reach the position P11, the oblique portion 192b-2 guides the pin 191b, and the clamper holder 191 is positioned at the intermediate position. Hm, Clamper 3
8A reaches the height position H11.

In this state, as shown in FIG.
The turntable vertical movement mechanism 114 operates, and the turntable 37A moves upward to reach the support position H21 for supporting the disk 11 and the magnet 37 in the turntable 37A.
Ac magnetically attracts the iron plate piece 38Ad in the clamper 38A, and the disk 11 is clamped on the turntable 37A.

When the turntable 37A is lifted after the clamper 38A is positioned at the clamp position in this manner, the magnet 37Ac in the turntable 37A effectively uses the magnetic attraction force for attracting the iron plate piece 38Ad in the clamper 38A. It can be clamped.

Thereafter, the loading arm 140 further rotates counterclockwise, as shown in FIG. 44 (D). That is, the top surface portion 140f-2 of the cam 140f pushes the pin portion 192e, the clamp slider 192 further slides in the direction A3 to reach the position P12, the lower portion 192b-3 guides the pin 191b, and the clamper holder 191 reaches the lower position Hl, is separated from the flange 38Ab, and floats in the annular groove 38Ac.

Here, a case where the disc 11 is shifted from the reproduction position by a predetermined dimension or more will be described. When the turntable 37A moves upward, as shown in FIG. 45B, the turntable 37A pushes up the vicinity of the center hole of the disk 11 and deforms the disk 11 into an umbrella shape.

As shown in FIG. 45A, the clamper holder 191 is already located at the intermediate position Hm, and the allowance for the displacement of the clamper 38A in the Z1 direction is limited to the dimension b1. For this reason, the upward movement of the turntable 37A moves to the original height position H21 as shown in FIG.
The position is limited to a slightly lower position H22.

Therefore, compared with the case where the turntable 37A moves upward to the original height position H21, the disk 11
The size of pushing up near the center hole of the
The amount of deformation when deforming into an umbrella shape is limited to a small amount.
Next, the operation for releasing the clamp of the disk will be described.

When the motor 174 rotates in the reverse direction and the loading arm 140 rotates clockwise, the state becomes as shown in FIG. That is, the slope 140f-
2 presses the pin portion 192e, the clamp slider 192 slides in the A3 direction to reach the position P11, and the oblique portion 192b
-2 guides the pin 191b, the clamper holder 191 moves up slightly, reaches the intermediate position Hm, and is in a state of supporting the flange portion 38Ab of the clamper 38A. Clamper 38
A stays at the height position H11.

In this state, as shown in FIG.
The peripheral edge of the disk 11 is gripped, and the turntable vertical movement mechanism 114 operates to lower the turntable 37A. Therefore, the turntable 37A is separated from the clamper 38A, reaches the position H20, and the clamp of the disk 11 is released.

When the turntable 37A is moved down,
Magnet 37Ac and clamper 38 in turntable 37A
The magnetic attraction with the iron plate piece 38Ad in A is forcibly separated. Until the magnetic attraction is forcibly separated, the clamper 38A is about to be displaced downward with the downward movement of the turntable 37A. When the clamper 38A is displaced downward, the disc 1 whose peripheral edge is
1 is deformed into an inverted umbrella shape. However, the clamper holder 191 has already moved slightly upward to reach the intermediate position Hm, supporting the flange portion 38Ab of the clamper 38A, and the displacement of the clamper 38A in the downward direction is limited. Therefore, when the clamp is released, the disk 11 does not deform into an inverted umbrella shape.

Thereafter, the loading arm 140 is further rotated clockwise, as shown in FIG. 46 (C).
That is, the pin portion 192e reaches the foot of the cam 140f,
Get over the top 140f-2. Therefore, the clamp slider 192 slides in the A4 direction to reach the position P10,
The upper portion 192b-1 guides the pin 191b, the clamper holder 191 reaches the high position Hu, the clamper 38A is slightly moved up to the high position H10, and floats from the unclamped disk 11.

[0177] 7. [Connecting Mechanism of Disk Playback Unit 32A and Disk Storage Unit 33A] (FIGS.
8) The disc reproducing device 30A has a coupling mechanism 200.
The coupling mechanism 200 mechanically connects the disk reproducing unit 32A and the disk housing unit 33A when the disk transport mechanism 34A operates, and the two-side rotating mechanism 35
A does not operate even if it tries to operate, that is, the disk reproduction unit 32A and the disk accommodation unit 33A
And does not rotate.

As shown in FIG. 47, the connecting mechanism 200
Connecting recess 109b at the tip of eject lever 109
And the holding finger 131a at the tip of the stock arm 131
It is composed of That is, the coupling mechanism 200 is entirely composed of existing components, and is configured without using any special components.

When the disc transport mechanism 34A is in the initial state shown in FIG. 32, the eject lever 109 is
7A, the eject lever 109 and the stock arm 131 are not connected, and the disc reproducing unit 32A and the disc housing unit 33A are not connected and can freely rotate. That is, when the two-side rotating mechanism 35A operates, the disc reproducing unit 32
A and the disk accommodating unit 33A are in a rotating state.

The two-way rotating mechanism 35A operates to rotate the disk reproducing unit 32A and the disk accommodating unit 33A, so that the disk reproducing unit 32A faces the predetermined disk accommodating portion 41A of the disk accommodating unit 33A. Thereafter, when the disk transport mechanism 34A starts operating, the eject lever 109 rotates in the M1 direction, and the distal end 109c of the eject lever 109 is
By pressing 1b, the stock arm 131 pivotally rotates in the N1 direction.

When the eject lever 109 starts to rotate in the M1 direction, as shown in FIG.
09b is the holding finger 13 at the tip of the stock arm 131.
Start fitting with 1a. The eject lever 109 and the stock arm 131 rotate to the position shown in FIG. 48 (C), and the pressing finger 131a fits deeply into the connecting recess 109b, and the eject lever 109 and the stock arm 1
31 are mechanically connected.

As a result, the disk reproducing unit 32A
And the disk housing unit 33A are mechanically connected,
Disk playback unit 32A and disk storage unit 3
3A is a state in which the rotation is prohibited. Therefore, when the disk transport mechanism 34A is operating, the two-side rotating mechanism 35A is not electrically operated. However, for example, the control is disturbed due to noise or the like. Attempting to do so, the disk reproducing unit 32A and the disk housing unit 33A do not rotate. For this reason, the disc reproducing unit 32A and the disc accommodating unit 33A are reliably maintained in a predetermined positional relationship. Therefore, the disk transport by the disk transport mechanism 34A is reliably performed without any trouble.

The disk 11 transported outside the disk storage unit 33A and the disk storage unit 33
It is possible to reliably prevent an accident that the disk 11 is damaged due to collision with another disk 11 accommodated in A. Therefore, as shown in FIG. 12, under the condition that sufficient reliability is guaranteed, the disk reproduction unit 32
A and the disk housing unit 33A are arranged close to each other. Therefore, the disc reproducing device 30A has the depth dimension L
10 is as short as possible. Also, since the depth dimension L10 of the disc reproducing device 30A is short,
The transport distance of the disk 11 is shortened, and the time required for transporting the disk 11 is shortened.

8. [Flap 112 and Flap Opening Mechanism 113] (FIGS. 49 to 51) As shown in FIG. 49 and FIG.
The hole 112a-1 of the arm 112a on the X2 side is inserted into the pin 40 on the side of the chassis 103 of the loading assembly 100.
A, the fork 112b of the arm 112b on the X1 side.
-1 is fitted to a pin 40Aa corresponding to the pin 40A so as to be rotatable in the B3 and B4 directions.

A slider 210 is provided on the X2 side of the chassis 103 so as to be slidable in the Y1 and Y2 directions. Hole 210a on the Y2 end side of slider 210 and flap 112
The pin portion 112a-2 of the arm portion 112a is fitted,
The slider 210 and the flap 112 are connected. The slider 210 is urged in a Y1 direction by a spring 211, and the flap 112 is urged in a B4 direction which is a closing direction. In this state, the flap 112 holds the front bezel 39 as shown in FIGS. 51 (A) and (B).
A opening 71A is closed.

The slider 210 has a finger 210b. The finger portion 210 b protrudes to a position on the chassis 103 where the finger portion 210 b is pressed by the pin 146. When the disc transport mechanism 34A operates to eject the disc 11 from the disc reproducing device 30A, FIG.
(B), as shown in FIG. 51 (C), at the final stage of the operation, that is, immediately before the disc 11 is ejected, Y
The pin 146 that has moved in two directions presses the finger 210b, the slider 210 moves in the Y2 direction against the spring 211, the flap 112 rotates in the B3 direction, and the opening 71A of the front bezel 39A is opened. . As soon as the opening 71A of the front bezel 39A is opened, the disk 11
Project from the opening 71A.

Here, a state in which the flap 112 covers the opening 71A of the front bezel 39A will be described. The flap 112 is attached to the chassis 103 of the loading assembly 100, is urged by a spring 211 in a direction B4, which is a direction in which the flap 112 is closed via the slider 210, and has a support projecting behind the opening 71A of the front bezel 39A. It hits the sponge 213 on the base 39Ab.

For this reason, as shown in FIGS. 51 (A) and (B), when the disc rotating unit 32A swings around the pins 40A and 40Aa, the slider 210 is moved when the two-way rotating mechanism 35A operates. Is slightly slid, so that the flap 112 is attached to the sponge 2 on the pedestal portion 39Ab.
Keep hitting 13. That is, the disc reproducing unit 32
The swing of A is absorbed by the slight sliding of the slider 210, the flap 112 continues to abut on the receiving part 212b, and the opening 71A of the front bezel 39A keeps being closed by the flap 112. In this way, even if the disk reproducing unit 32A swings, the flap 112
Since the relative positional relationship between the flap 112 and the front bezel 39A does not change, the size (height dimension) e of the flap 112 does not need to be particularly large, and a minimum size that is one size larger than the opening 71A is sufficient. Therefore, the disc reproducing device 30A
Can be made thin.

Further, the flap 112 keeps hitting the sponge 213 on the receiving portion 39Ab, and no gap is formed between the flap 112 and the sponge 213. Therefore, the portion of the opening 71A of the front bezel 39A of the disc reproducing device 30A has good dustproofness.

Further, the flap 112 is attached to the front bezel 3
9A, the ejected disk 11
For example, even when a finger is inserted into the center hole and pulled out, the flap 112 does not interfere
Is easy to pull out. 9. [Configuration around Disk Insert Port Member 111] (FIG. 52)
Through FIG. 54) As shown in FIGS. 52, 53 (A) and (B), X1, X1 on the back side of the disc insertion member 111 which is a resin molded product.
A disk support member 220 is attached to the X2 end side. The disk insertion member 111 is fixed to the chassis 103.

The disk support member 220 is made of sheet-like felt, has a T-shaped slit 220a oriented in the horizontal direction, and is provided with a pair of wings 22 by the slit 220a.
0b and 220c are formed. Wings 22
Ob, 220c may be elastically warped. The disk support member 220 has a plurality of holes 220d corresponding to the plurality of projections 111b on the back side of the disk insertion member 111.

Reference numeral 221 denotes a mounting member, and three arms 221a, 221b, 22 formed by bending a wire into a U-shape.
1c and finger portions 221d and 221e formed by rolling the tips of the arm portions 221b and 221c outward. FIG. 53 (A)
As shown in the figure, on the back side of the disc insertion member 111,
In addition to the plurality of protrusions 111b, a hook portion 111c for attaching the attachment member 221 and holes 111d, 1
11e.

The disc supporting member 220 is positioned by fitting the hole 220d into the projection 111b, and
20a and the ends of the wing portions 220b and 220c face each other so as to be positioned within the insertion opening 111a of the disk insertion member 111, and are pressed against the back surface 111f of the disk support member 220 by the mounting member 221 for mounting. It is. The attachment member 221 has the arm portion 221b hooked on the hook portion 111c and the finger portions 221d, 221.
e is inserted and attached to the holes 111d and 111e.

The arms 221b and 221c extend laterally past the protrusion 111b and press the disk supporting member 220. The disk supporting member 220 is firmly attached to the same degree as the adhesive. Here, when the disk 11 is inserted, the disk support member 220
As shown in (A), the wings 220b and 220c are warped so as to be elastically turned up. Warped wings 220b, 220c
Supports the disk 11 with the elastic restoring force of the warped wings 220b and 220c themselves. When the disk 11 is ejected, as shown in FIG. 54 (B), the wings 220b and 220c warp and support the disk 11 in the same manner as when the disk is inserted. As described above, the disc supporting member 220 is a consumable that is rubbed and gradually worn by the disc 11 each time the disc 11 is inserted or ejected, and a certain period of time has elapsed since the use of the disc reproducing apparatus 30A was started. After that it should be replaced with a new one. The mounting member 221 is easily removed by removing the finger portions 221d and 221e from the holes 111d and 111e. By removing the mounting member 221, the disk support member 220 is removed and replaced with a new one. Therefore, the disk insertion member 111
There is no need to replace the parts, and the maintainability is good.

The back surface 11 of the disk support member 220
1f is a tapered surface that faces in the Y1 direction as approaching the insertion opening 111a, and the wings 220b and 220c also have a mountain shape that is convex in the Y1 direction toward the slit 220a, and is angled in the Y1 direction with respect to the vertical surface. θ1 is inclined.

For this reason, when the disk 11 is inserted, as shown in FIG.
The angle at which c warps remains at θ2. This angle θ2 is smaller by θ1 than the warp angle when the wings 220b and 220c are vertical surfaces, and the warped wings 220b and 220c
c, the elastic restoring force is small, and the warped wings 220b, 220
The resistance force (load of the insertion of the disk 11) exerted on the disk 11 into which the c is inserted is small, and therefore, the insertion of the disk 11 is performed with a lighter force and a better feel as compared with the related art.

The positions of the centers where the wings 220b and 220c are warped are positions that are pressed by the arms 221b and 221c, and are vertically separated from the positions of the edges of the insertion ports 111a. In the configuration where the wings are bonded,
The position of the warped center is the position of the edge of the insertion port 111a. Therefore, even by this, the angle at which the wing portions 220b and 220c warp is small.

When the disc 11 is ejected and when the ejected disc 11 is pulled out, the operation shown in FIG.
As shown in (B), the angle at which the wings 220b and 220c warp is θ4. This angle θ4 is determined by the wings 220b, 2
The angle at which the warped wings 220b, 220c are elastically restoring force is large, and the force supporting the disk 11 from which the warped wings 220b, 220c are pulled out is larger than the warped angle when 20c is a vertical plane by θ1. Increases. Therefore,
When the disk 11 is pulled out, even if the fingertip comes off the disk 11, the disk 11 is warped to the wing 2
The disk 11 continues to be firmly supported by the disks 20b and 220c, so that the disk 11 does not come off and fall off, which is safe.

The disk support member 220 is not limited to felt, but may be rubber or sponge. Also,
The disk support member 220 can be applied to support a card-shaped recording medium.

10. [Operation for Detecting Insertion of Disk 11 from Outside] (FIGS. 55 to 57) In the present embodiment, when the disk transport mechanism 34A in the disk insertion waiting state is pressed by the disk 11 inserted from the outside. Then, the drive mechanism assembly 110A is slightly moved, and the slight movement of the drive mechanism assembly 110A at this time is detected to detect that the disk 11 has been inserted.

FIGS. 57A to 57G show the operation of each member when detecting that the disk 11 has been inserted from the outside. When the disk 11 is inserted from the outside, the disk transport mechanism 34A is in a disk insertion waiting state shown in FIGS.

For the sake of convenience, the drive mechanism assembly 11 when the disk transport mechanism 34A is in a disk insertion waiting state will be described.
The operation at 0A will be described. As shown in FIG.
88 and the switch 189, and the slide member 105A is Y
The L-shaped arm portion 105Af is disposed at a position where the arm portion 105Af abuts when sliding in two directions, and is fixed on the sub-chassis 150.

When the disc is ejected, the motor 17
4 continues to rotate forward, the clamp of the disk 11 is released,
The disk transport mechanism 34A transports the disk 11 from the playback position in the Y2 direction to a position outside the disk playback device. The drive mechanism assembly 110A is in the state shown in FIG. The L-shaped arm 105Af presses the switch 189 to turn on the switch 189, and the L-shaped arm 105Af presses the leaf spring 188.

The pin 183Aa of the link arm 183A is connected to the fourth Y-direction groove 105Ad- of the slide member 105A.
7 and the link arm 1
Since the pin 183Ab of 83A is located in the arc-shaped groove 177Aa-1 of the cam gear 177A, the slide member 1
05A is slidable in the Y1 direction, and the cam gear 1
77A is also in a state capable of rotating in the counterclockwise direction.

Here, while the cam gear 177A is associated with the loading arm 140, the sliding member 1
05A is not associated with loading arm 140. Therefore, the load when moving the slide member 105A is smaller than the load when rotating the cam gear 177A. In addition, the slide member 105A is
8 energized. Therefore, the sliding member 10
5A is easier to move than the cam gear 177A.

Therefore, when the motor 174 rotates in the reverse direction, first, the slide member 105A moves to the position shown in FIG. 55B in the Y direction (see FIG. 57C), and the switch 18
5 is turned off, and then the cam gear 177A is rotated counterclockwise to the position shown in FIG. 55 (C) (FIG. 57).
(D)).

When the motor 174 stops rotating in the reverse direction, the disk transport mechanism 34A enters a disk insertion waiting state shown in FIGS. 28 and 29, and the drive mechanism assembly 110A is turned off as shown in FIG.
The state shown in FIG. The switch 189 is off. The pin 104 is connected to the Y1 of the mountain-shaped guide groove 105c.
The slide member 105A has a play that is movable in the Y2 direction by a distance a1 in a position closer to the Y2 direction in the side skirt portion 105c-3.

Next, the operation when the disk 11 is inserted from outside will be described. When the disk 11 is inserted in the Y1 direction, as shown in FIG.
The letter-shaped roller 62A is pushed in the direction K2 and inserted. When about three-fourths of the disk 11 is inserted, the leading end of the disk 11 in the insertion direction is the I-shaped roller 6.
At 1A, the operator suddenly feels resistance. The operator presses the disk 11 against the resistance.

By the operation of pushing the disk 11 at this time, the I-shaped roller 61A slightly moves in the Y1 direction,
The loading arm 140 is slightly rotated in the L2 direction via the link. L2 of loading arm 140
A slight rotation in the direction causes the gear 179 to rotate counterclockwise. When the gear 179 rotates, the gear 183 rotates clockwise, the cam gear 177A rotates counterclockwise, and at the same time, the gear 172 rotates counterclockwise.
