When the disk D is returned to the concave portion C1' of the disk mounting plate C1, if the automobile A shakes, the disk D will be rotated and stored in the case Ca. You may get caught up in the situation. If an attempt is made to store the disc mounting Fi Ct in the case C3 in this state, the disc D will be sandwiched between the disc mounting plate C1 and the opening of the case C3 and cannot be stored, resulting in malfunction.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problems, and its purpose is to forcibly push the outer peripheral edge of the disc when storing the disc mounting plate in the case, so that the edge of the disc mounting plate is By returning the disc that has landed on the disc to the recess in the disc mounting plate, the disc will not be caught between the disc mounting plate and the opening of the case when the disc mounting plate is stored in the case, and malfunctions will be prevented. It is an object of the present invention to provide a disc position adjusting device for a disc player which prevents the occurrence of disc positioning.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention has a disc mounting plate that moves from the edge of the disc mounting plate to the recess side and rides on the edge when the disc mounting plate is rotated for storage. The gist is that the disc is forcibly dropped into the recessed part of the disc i31 placing plate so that the disc is not pinched between the disc placing plate and the opening of the case.

(Example of the invention) Hereinafter, embodiments of the player body B will be described with reference to the drawings.

In FIGS. 2 to 4, 2 and 2 are left and right side plates constituting the frame, and 3 is a magazine holder placed between the left and right side plates 1 and 2 with slide plates 4 and 5, which will be described later. Guide bins 3a to 3C are formed on the left and right sides. Further, on the lower surface of the magazine holder 3, a magazine push-out arm 6 having a fan-shaped gear portion 6a is pivotally supported at one end and is biased in the magazine push-out direction by a spring 6b.

Furthermore, an upright piece 6C is integrally formed at one end of the gear part 6a of the push-out arm 6, and when the magazine C is inserted through the opening of the magazine holder 3, the upright piece 6C comes into contact with the front surface of the magazine C, causing the magazine In response to the push-in of C, the magazine C is rotated against the spring force of the spring 6b, and the magazine C is inserted and set.

Note that the upright piece 6C faces the flat surface of the magazine C when the magazine C is inserted in the normal direction, so the upright piece 6c slides on the flat surface as the magazine C is pushed. The push-out arm 6 is rotated (
5), when the magazine C is inserted upside down, the upright piece 6C comes into contact with the front step C6 of the magazine C and becomes locked, so the push-out arm 6 cannot rotate and the magazine C (Fig. 6). Therefore, since the magazine C cannot be inserted with the upper and lower surfaces reversed, malfunctions due to incorrect insertion can be prevented.

Further, the gear 6a of the push-out arm 6 is meshed with the gear 7a of the rotary damper 7 attached to the lower surface of the magazine holder 3, and is formed so that the return speed of the push-out arm 6 is slow. is released from the magazine holder 3 slowly.

When the magazine C is inserted and set into the magazine holder 3, an engaging claw is rotatably attached to the side surface of the magazine holder 3 and is always spring-biased in a direction protruding inward from the side surface. The arm 8 is formed to lock the magazine C by engaging with a locking groove 04 formed on the side surface of the magazine C.

Slide plates 4 and 5 interposed between the frame 1 and the magazine holder 3 have stepped cam holes 5a (slide plate 4 has guide bins 3a, 3
There are two cam holes into which b is inserted (not shown)
are formed, and each slide plate 4, 5 is supported so as to be slidable in the horizontal direction with respect to the left and right side plates 1, 2. Further, the guide bins 3a to 3C of the magazine holder 3 pass through each cam hole of the slide plates 4 and 5, and the left and right side plates 1,
2 (the slide plate 4 has two vertical holes into which the guide bins 3a and 3b are inserted, but they are not shown).

In addition, a rotating plate 9, which is pivotally supported on the outside of the left and right side plates 1 and 2,
The tip of 10 is pivotally supported by the guide bins 3b and 3C,
The guide bin 3b is always guided by the spring force of the springs 9a and 10a stretched at the other end.

3c is biased upward by a spring, thereby pushing the magazine holder 3 upward.

Reference numeral 11 denotes an engaging protrusion 4a that is pivotally supported approximately at the center on the upper surface of the magazine holder 3, and has sliding plates 4 and 5 at both ends.

5b, and when one of the slide plates is moved, the other slide plate is moved in the opposite direction at the same speed.

Reference numeral 12 denotes a slide plate driving device for moving the slide plate 5, which is composed of a motor 12a and a reduction gear group 12b, and the final gear meshes with a gear 5C formed on the upper surface of the slide plate 5.

When the motor 12a of the slide plate driving device 12 is driven, the slide plate 5 is moved in the horizontal direction via the reduction gear group 12b, so that the guide bin 3C guided by the cam hole 5a of the slide plate 5 is Since it is also guided by the vertical hole 2a of the right side plate 2, it moves in the vertical direction. Furthermore, when the slide plate 5 starts to move, the slide plate 4 also moves in the horizontal direction via the synchronization plate 11, although the five slide plates are in the opposite direction. The bins 3a and 3b move up and down in the same manner as described above. Therefore, the magazine holder 3 moves up and down as the guide bins 3a to 3C move up and down.

The above-mentioned retaining claw arm 8 is attached to the slide plate 4 when the slide plate 4 finishes moving to the left in FIG. 2 (in this state, the magazine holder 3 has moved to the uppermost position). The formed protrusion 4b pushes the protrusion 8a, rotates it counterclockwise, and leaves the retaining groove 04 of the magazine C. Therefore, magazine C will be in a free state, so
It is gently discharged by the spring force of the spring 6b of the push-out arm 6.

The above explanation is about setting and ejecting the magazine C into the magazine holder 3, and also about moving the magazine holder 3 up and down.Next, the disc D is pulled out from the magazine C set in the magazine holder 3 and played. Let's explain the parts.

In FIG. 2, reference numeral 13 denotes a pickup drive device, which is comprised of a pickup drive motor 13a, a threaded rod 13b rotated by the motor 13a, and a pickup 13c that moves as the screw rod 13b rotates. Further, 14 is a turntable drive motor that drives the turntable 15.

In FIG. 4, a control cam drive motor 16 is fixed to the first chassis 19a and drives a control cam 18 to be described later, and a worm 16 is fixed to the output shaft of the motor 16.
The worm wheel 17 is rotated via a. A small gear 17a formed integrally with the worm wheel 17 is meshed with an internal gear 18a formed on a part of the control cam 18.

The control cam 18 is pivotally supported by a shaft installed in a second chassis 19b that connects the left and right side plates 1 and 2 and fixes the first chassis 19a via a spacer (not shown). A fan-shaped internal gear 18a that meshes with the small gear 17a is formed, and the internal gear 18a
A higher cam portion 18b is formed at a position substantially opposite to the cam portion 18b.
Further, a control protrusion 18c is provided near the end of the internal gear 18a.
are integrally formed.

Reference numerals 20 and 21 denote first and second rotating plates that are rotatably supported on the upper surface of the second chassis 19b.
A roller 2 protruding from the first rotating plate 20 located on the b side
0a is in contact with the cam portion 18b of the control cam 18. Spring 22.23 is stretched between the first and second rotating plates 20.21 and the second chassis 19b, and the springs 22.23 are attached to the second chassis 19b side. It is strong. Therefore, the roller 20 of the first rotating plate 20
a is pressed against the cam portion 18b. This first rotating plate has a first chassis 19a that passes through the second chassis 19b.
One end of the connecting arm 24 reaching the upper surface of the connecting arm 24 is pivotally supported.

Reference numeral 25 denotes a third rotating pin rotatably supported on the upper surface of the first chassis 19a, and a pin 25a protruding from the side is inserted into an elongated hole 24a formed at the other end of the connecting arm 24. At the same time, a spring 26 is stretched between the two. On both sides of the tip of this third rotary plate 25, vertical plate portions 2 of the T-shaped disc pressing member 27 made of synthetic resin are provided.
The upper ends of 7a are each pivotally supported. Approximately in the middle of this vertical plate portion 27a, there is a first rotary plate 25 having one end pivotally supported.
The distal end of a parallel arm 28 whose one end is pivotally supported by the chassis 19a is pivotally supported. Therefore, when the third rotating plate 25 is rotated, the disk pressing member 27 is moved vertically in parallel. Note that the horizontal plate portion 2 of the disk pressing member 27
Although not shown, a cushioning material such as felt is attached to the lower surface of 7b. Further, the vertical plate portion 27a of the disk pressing member 27 comes into contact with a stopper piece 19a' cut and raised from the first chassis 19a, and the amount of descent of the disk pressing member 27 is regulated.

Reference numeral 29 denotes a clamper that is rotatably supported at the tip of the second rotary plate 21, and 30 indicates a third chassis 19c that is attached between the left and right side plates 1 and 2 similarly to the second chassis 19b.
Three support columns 30a are formed at intervals of about 120 degrees as clamper support members inserted through two guide bins 19d planted in the clamper support member. Since this clamper support member 30 is always biased toward the clamper 29 by a spring 30b inserted into one of the guide bins 19d, the clamper 29 is held in a horizontal state by the three support columns 30a. (See Figure 7).

When the control cam 18 is rotated by the motor 16 and the roller 20a of the first rotating plate 20 is separated from the cam portion 18b of the control gum 18, the first rotating plate 20 is rotated by the spring force of the spring 22. The clamper 29
moves to the turntable 15 side and clamps the disc D. During this movement of the clamper 29, the clamper support member 30 is moved to the clamper 29 by the spring 30b.
Since the clamper support member 30 is biased toward the side by a spring, as the clamper 29 moves, the clamper support member 30 also moves while in contact with the clamper 29, and the clamper 29 clamps the disk D between it and the turntable 15. Hold it in a horizontal position until just before. Therefore, since the clamper 29 is accurately inserted into the hole of the disk D, it is possible to clamp the disk D without eccentricity between the disk D and the turntable 15.

Further, when the first rotating device 20 is rotated, the second rotating plate 21 is also rotated by the spring force of the spring 23, so the third rotating plate 25 is rotated via the connecting plate 24. be moved.

Along with this rotation, the disk pressing member 27 is pressed against the parallel arm 2.
8, the clamper 2 moves in parallel and rises.
The disc D is moved toward the turntable 15 while being held in a parallel state by the curve between the upper surface of the clamper 29 and the horizontal plate portion 27b of the disc pressing member 27. Therefore, disk D
can be clamped between the turntable 15 and the clamper 29 in a horizontal state (see Fig. 8).
.

Further, when the disk D is returned to the disk mounting plate C1, the rotary plate 20 rotates counterclockwise to lower the disk D. However, when the disk D gets caught in the middle and cannot be lowered completely, the disk pressing plate 27 is forced to move. In order to push down the disk D, the elongated hole 24a of the connecting arm 24 comes into contact with a pin 25 when the rotary plate 20 is in the lowered position.

31 is an upper slide plate attached to the second chassis 19b so as to be freely movable in parallel; 32 is a lower slide plate attached to the upper slide plate 31 so as to be movable in parallel;
A spring 33 is stretched between the two, and the lower slide plate 3
2 moves, the upper slide plate 31 also moves together. And the long hole 32 of the lower slide plate 32
The control protrusion 18c of the control cam 18 is engaged with a, and when the control cam 18 rotates, the lower slide plate 32 moves, and accordingly, the upper slide plate 31 also moves in the same direction by the spring force of the spring 33. It is something to do.

The second chassis 19b also includes a position detection switch Si which is turned on and off by the movement of the upper slide plate 31.
~ A standby position where S3 is attached and the upper slide plate 31 does not push out the disk mounting plate C1 from the position magazine C shown in FIGS. 2 and 4 (position shown in FIGS. 2 and 4)
, all the position detection switches S1 to S8 are turned on, and the disk mounting plate C1 is pushed out from the magazine C by the push-out arm 34, which will be described later, and the disk D on the disk mounting plate C1 is moved to the turntable 15 When in the playback standby position that has reached the position, the position detection switch S1
and 32 are in the off state, and when the disc D is in the position where it is clamped by the turntable 15 and the clamper 29,
All position detection switches S1. The position detection switches 31 to S3 are arranged so that -sa is in the off state.

34 is approximately C rotatably supported by the second chassis 19b.
It is a letter-shaped extrusion arm, and one end 34a is attached to the upper slide plate 3.
1 and when the upper slide plate 31 moves, the push-out arm 34 rotates, and the other end 34b enters the hole Cs of the magazine C inserted into the magazine holder 3 and pushes the disk mounting plate 0 plate. This is rotated and pushed out of the case C8. At this time, the center position of the disk mounting plate C1 is rotated extra so that the center position of the turntable 15 is located in front of the center position of the turntable 15 in the extrusion direction. When the disk D is lowered by the retreat of the clamper 29, the disk D is placed on the disk mounting plate C.
It is placed in front of 1 in the return direction (see solid line in Figure 12).
.

Then, when the upper slide plate 31 moves in the opposite direction, the pushed-out disk mounting plate C1 is pushed back by the side surface that is engaged with the upper slide plate 31, and the disk mounting plate C1 is moved into the case C3. It will be stored. When this disc mounting plate C1 is stored in the case C3, the disc D that has climbed onto the edge of the disc mounting plate C1 comes into contact with the opening of the case C3 and is returned to the recess C1' of the disc mounting plate C1. Therefore, the disk mounting plate C1 is reliably stored (see the two-dot chain line in FIG. 12).

In addition, the upper and lower sliding plates 31 and 32 are divided into two pieces.
By allowing only the lower slide plate 32 to move even after the upper slide plate 31 finishes pushing out the disk mounting plate C1, the control cam 18 can be rotated extra. This is to ensure that the movable plate 20 is rotated extra and the horizontal plate portion 27b of the disk pressing member 27 is completely separated from the disk D clamped by the turntable 15 and the clamper 29.

35 is the second chassis 19b at the most extreme position of the disk D placed R on the extruded disk mounting plate C1.
A synthetic resin disk return guide fixed to the
A tapered part 35a is formed on the upper surface, and the tapered part 35a has a shape that is set back from the leading edge of the disc b that is accurately placed on the disc mounting plate C1. A vertical portion 35b is formed in a shape that matches the leading edge of the disk D placed on the disk (see FIGS. 8 and 9).

Therefore, if the disc D which is being pushed up by the clamper 29 and is in the reproducing state is displaced due to external vibrations etc. as shown in FIG. The disk mounting plate C1 is returned to its normal position by the tapered portion 35a, and is held at the normal position by the vertical portion 35b.

36 is rotatably attached to the second chassis 19b at two locations: the extruded tip of the disk placement plate C1 in the extrusion direction, and the most extreme end of the disk placement plate C1 through an interval of approximately 90 degrees from this tip. A pair of pivotally supported disc return arms each have a spring 37 attached to the second chassis 19.
b, and is spring-biased in the counterclockwise direction in FIG. Two protrusions 36a and 36b are formed on each of the disk return arms 36, and the protrusion 36a on the side closer to the rotational fulcrum is attached to the protrusion of the disk placement plate C1 when the disk placement viC1 is completely pushed out. Edge C,
/ is formed so as to come into contact with. Then, when the disk mounting plate C1 that has been completely pushed out is rotated to be stored in the case C3, the protrusion 36a of the disk return arm 36 that has been in contact with the disk mounting plate C1 moves to the protrusion C on the disk mounting plate C1. / since the disc return arm 36
are rotated clockwise by the spring force of the spring 37, respectively. Therefore, the other protrusion 3 of the disk return arm 36
6b moves to the disk placement plate C1 side, and the disk D (which is not placed in the disk placement plate C1 in a normal state)
The device is placed in a normal state by pressing the sides indicated by the one-dot chain line and two-dot chain line in Fig. 9.

Note that the disk return arm 36 is regulated by a stopper 38 attached to the second chassis 19b so that it does not rotate more than necessary due to the spring force of the spring 37.

Next, the overall operation will be explained based on the above configuration.

First, when magazine C is inserted into magazine holder 3,
The push-out arm 6 is rotated by the front surface of the magazine C, and the retaining claw arm 8 is engaged with the locking groove 04 of the magazine C to lock the magazine C at the rotation end position of the push-out arm 6.

In this state, when the remote control device F is operated to select the disc D desired to be played, the motor 12 is driven and the slide plate 5 is moved. As the slide plate 5 moves, the slide plate 4 also moves via the synchronizing plate 11, so the magazine holder 3 moves up and down guided by cam holes formed in each slide plate 4. The disk mounting plate C1 on which the disk D to be loaded is placed is the push-out arm 34.
It stops when it comes to a position facing the

Next, the motor 17 is rotated and the control cam 18 is rotated, so the upper and lower slide plates 31 and 32 are moved and the push-out arm 34 is rotated, so that the desired disc D is produced! ! Push out the placed disk mounting plate C1, and move the vertical slide plate 31 with the hole of the disk D positioned on the turntable 15.
．． 32 stops moving.

Furthermore, since the motor 17 continues to rotate in this state, the control cam 1 rotates further and the roller 20a of the first rotating plate 20 separates from the cam part 18b, so the clamper 29 moves toward the turntable 15. Clamp disk D with the During this movement of the clamper 29, the clamper support member 30 holds the clamper 29 in a horizontal state until just before it clamps the disk D between it and the turntable 15. Further, when the first rotating plate 20 is rotated, the second rotating plate 21 is also rotated, so the third rotating plate 25 is rotated via the connecting plate 24, and the disk pressing member 2
7 is moved in parallel and raised, and the disk D is pushed up by the clamper 29 and comes into contact with the upper surface of the moving disk D.
is held in a parallel state between the upper surface of the clamper 29 and the disk pressing member 27 and moved toward the turntable 15.

Therefore, the disk D is clamped between the turntable 15 and the clamper 29 in a horizontal state.

Next, when the disk D is clamped, the motor 13a
rotates and moves the pickup 13c, so that reproduction is started.

In addition, in this playback state, that is, in a state in which the disc D is clamped by the turntable 15 and the clamper 29, the remote control device F can switch the mode from the playback state to the radio reception state, or turn off the ignition key. In such a case, the disk D will remain clamped.

If the disc D is left clamped for a long time, if the player body B is used in a car, the outer periphery of the disc D may sag due to solar heat etc., making playback impossible, or if the disc D is a single CD. In such cases, problems arise such as the adapter attached to the outer periphery of the adapter falling due to vibrations of the vehicle and becoming impossible to remove.

Therefore, in the present invention, when the three switches s, -s3 controlled on/off by the upper slide plate 31 are all off, the mode of the remote control device F is changed, or when the ignition switch is turned off, The motor 16 is reversely rotated in response to a command signal from the remote control device F, and the control cam 18 is reversely rotated to rotate the vertical slide plate 31.
．． Move 32. Then, the upper slide plate 31
, when the third switch S2*S3 is turned on, the remote control device F stops the rotation of the motor 16. When the second and third switches S 2 s 53 are on, the clamper 29 is lowered as described above.
! (FIG. 7), the disk D is returned to the disk mounting plate C1, and the above-mentioned problem is solved.

When the playback is completed, the disk D is returned to the temporary disk placement C1 by the reverse operation to that described above, and the disk placement plate C1 is housed in the case C3 of the magazine C, and the remote control device F The magazine holder 3 moves up and down again based on the command from the user, and the above-described operation is repeated.

〔Effect of the invention〕

As described above, the present invention moves from the edge portion side of the disk placement plate to the recess side when the disk placement plate is rotated for storage,
The disc riding on the edge is forcibly dropped into the recess of the disc mounting plate, so that when the disc mounting plate is stored in the case, the disc is caught between the disc mounting plate and the opening of the case. Therefore, even when used in a vehicle, there is no malfunction caused by external vibration.
