Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc record playback device suitable for, for example, a DAD (digital audio disc), and particularly relates to a disc loading mechanism thereof.

Recently, in the field of audio equipment, a digital record playback method using ci' CM (pulse code modulation) technology is being adopted as much as possible in order to achieve high fidelity playback. In other words, this is what is called digital audio, and the audio characteristics do not depend on the characteristics of the recording medium and are much superior to the conventional five analog senses. This is because it is established in principle.

In this case, a system that uses a disk as a recording medium is called a DM system, and optical, electrostatic, and mechanical playback methods have been proposed, but none of them are possible. Even in the case where a reproduction method is adopted, the reproduction apparatus implementing the reproduction method is still required to be capable of satisfying various advanced functions and performances not found in the American version.

Of the optical playback methods, the one proposed as the CD (compact disc) method is □, diameter 1.
A disk with a diameter of 2 cm and a thickness of 2 m is driven by the CLV (Constant Linear Velocity) method at a variable rotational speed of about 500 to 200 m, with a track pitch of 1.6 μm and a single-sided disk. However, it is easy to see why, considering that it contains a huge amount of information that can be played back in stereo for about an hour.

Therefore, this invention has been made in view of the above point 6. Especially in a disc record playback device that drives the disc in a vertical position, it is possible to load the disc reliably in an organic and economical configuration. The object of the present invention is to provide an extremely good disk loading mechanism.

That is, the disc loading mechanism according to the present invention includes a disc pocket part for vertically inserting a disc, which is supported in the front part of the cabinet so as to be openable and movable, and this disc pocket part has a moving surface I: higher than the turntable in the cabinet. The disk is moved to the open state where the disk can be inserted, and from the first position, the disk is moved in the turntable direction g2 and the disk is loaded directly onto the turntable, and the disk loaded on the turntable is placed in the core disk pocket. It is characterized by having a second position in which it is in a closed state where it can be rotated inside the crane.

Hereinafter, with reference to the drawings, details of the case where the present invention is applied to a CD type DAD playback device as an embodiment of the present invention will be described with reference to the drawings.

Further, since the left and right sides of C% holder 1ull C = a pair of front holders fag, 111 are attached, there is a recess for inserting a disc between the opposing parts)illZ
F-color is formed, and a disk support lever Ill is provided at the bottom of the disk pocket @xye.

Here, the disk support lever IlK is the holder lever lII#r-IIT as shown in FIG.

Although it is supported freely, the spring RGG (see Figure 8) is always biased in the direction of arrow H, and the holder lever 1 int: is attached.
c It is like being forced.

The rear of the holder lever iia (= means the clamp lever 11- is connected to the clamp lever mounting plate Il with the axis IJj).
It is rotatably supported by K.

This clamp lever mounting plate 1' Rl is the chassis 114

Here, the long hole of the slider 114 is engaged with the bin 121 provided below the main slider 121, and the bin 161 is attached to the bent part.
A C spring IS# is engaged between the bush R5- and the bush R5-.

Note that lim in FIG. 6 is a reflective sensor for disc detection attached to the holder lever 1110.

In addition, l-1 is the introduction hole 1ai on the back side of holder l-5.
It has a guide 1111m which is provided centrally from n (see FIG. 2) and is combined with the center hole C of the disk IO1. In this case, the turntable 1151 is rotatably supported on the shaft of the motor 1 for driving the disc supported in the chassis 12, and these will be explained later in the disc drive and playback mechanism II. To explain the details of the single-day loading operation in the above-mentioned configuration, Figure 7 and Figure 7 are views from the right side of the state shown in Figure 3 when the disk pocket sLL has met the outer CLL. It shows the relationship between the main parts.

That is, in this state, the main slider 111 is completely lowered and one end of the loading lever 118 is pushed up from the uppermost end C of the elongated hole 16-. The situation is as follows.

However, in this case, the disc pocket part LL! Since the inclination of the holder lever 150 is regulated by the elongated hole 11rl+=, the inclination is smaller than that of the disc clamper 9188 and the lid 161 (which is provided on the outside).

So, in this state, the disc pocket msy.

If a disk 5o1 (not shown) is inserted into the
The aforementioned reflection sensor li# detects this and motor 11
A drive circuit (not shown) for the motor 6 to drive the motor 9: gives a start signal.

Here, the disc pocket part 17! ("1. The inserted disc 101 is placed under the support bins M J 5 m, 115b of the disc support lever 116 at llz places below it (
(see FIG. 9), so that the center of the disk is substantially aligned with the center of the turntable 16M.

Then, when the main slider 11g is moved upward as described above by the drive of the motor 1Mm, the lower end side 1 of the long hole 1ga is pushed down via the link 122 and the connecting lever 121. As a result, disc clamper 111J 71
6: The operation of pulling the disk pocket portion 110 in the direction of arrow B is started.

FIG. 10 shows the above operation; therefore, the disc clamper portion 180 and the disc pocket portion 1'16 have been retracted to the position at the moment when the disc 101 is to be pushed onto the turntable 161. .

In this state, the main slider JjJ has been moved considerably upward, and one end of the loading lever I1g is located directly at the boundary between the inclined portion and the horizontal portion of the elongated hole 160.

In other words, loading lever 1. Since the main ring Zjlt has not reached the vertical position, III is slightly tilted by 1:, but it is almost in a horizontal position.

At this time, Fig. 11 shows C: Part 1 of the cage and disc clamper.
80. That is, in this state, the clamper jjtF is the same as the state shown in FIG. Therefore, even if the disc 101 is tilted in the direction ε in which it comes into contact with the clamper rag due to gravity 12, it will not tilt. Contact direction ε: When tilted,
Since the disc 101 is pressed against the clamper 116, which is moved in the same direction, by the frictional force of the turntable 161, it has a function of correcting the inclination of the disc 101.

In addition, in this state, the disk support lever 111- is also in the eighth position.
There is the same state I11 as in the figure, but one end is coming into contact with the folded part of the clamp lever-bottle plate fJI.

Furthermore, the connecting bar 1ze connecting the left and right levers 1all and '11- is in contact with the clamp lever-tza, but since the spring ISM is not yet extended, r-, the spring Z##W of the clamp lever 110 Only weak pressure is applied. In addition, the left and right levers 1
0 Jl, the upper end of each of them is the link pin I g
4. Light contact with tgg.

1st! 13 shows a state in which disk loading has been completed, and the main slider lll1: has been raised to the top. In addition, the left and right connecting levers 1 ff 1
．． e, 14 # is tensioned by a spring 1111° 181, and pulls the loading lever 118 backward along the elongated hole 111-.

And, as for the clamp lever 111, the slider 114 is the main slider 11! + = Therefore, upward position: Because it is moved, it receives the tensile force from the 12 spring xsg and the arrow shown! By being rotated in the direction, the connecting par 12# is pushed down. As a result, the left and right levers tag and
11.11135, 116, and 114 are rotated to push down the clamper holder 111 in parallel C2. In other words,
As shown in Fig. 14 (1): clamper holder 117
Until then, the long hole J! 1m
1: Links 109, 111 and 110, 114 were fitted at the bottom of
As a result of the rotation of , as shown in FIG. 14(b), I: is accompanied by a parallel movement such that it is also moved downward in the figure so that it is fitted at the center of the two elongated holes 121jm. .

In addition, at this time, the clamper presser lever 111 is pushed in the direction of the arrow J, so that the clamper presser lever 111 is pushed in the direction of the arrow J.
The clamper 116 is also pressed in the same direction. In this case, since the disc 501 is in contact with the turntable l1il, the clamper lz6 moves toward the turntable 1617j with a constant pressure determined by the spring 151:
52. Being forced.

In this state, a gap is formed between the clamper J26 and the clamper holder 121, which is sufficient to allow the clamper 128 to rotate.

In addition, the rear end of the disk support lever 115 is in contact with the bent end of the clamp lever mounting plate 131, and the outer end is rotated horizontally.
m, 11Sb is spaced from the bottom edge of the disk lot (see Figure 1s).

In other words, the disk 101 is connected to the turntable I4. , f is loaded into the motor 1611; it becomes more freely rotatable, and here 6: Disk loading 1 = a series of necessary operations has been completed (2).

Note that the anti-rope swinging operation C for removing the disk IO1 from this state can be performed by following the completely opposite process to the above-mentioned loading operation, and will therefore be omitted.

In addition, when the disc loading is completed, the pickup introduction hole J ogb section (second
The optical pickup I'U is exposed from (see figure).
(See FIGS. 18 and 19) The signal surface of the disk 101 is reproduced in a linear tracking manner, and this will be explained in detail in the disk drive and reproduction mechanism section described later.

Next, the disk loading mechanism il!
10 The feature point C of a will be explained.

First, in order to easily and reliably load a disc, simply insert the disc 101 into the disc pocket 110 in a roughly straight shape C2, and the rest will be automatically performed.
1 can be loaded into a predetermined driving position.

This vertical disk loading mechanism is

tt, r2t, l*x, and this power transmission mechanism 1: a power source 1'39 that transmits power.

The second point is that in the above-mentioned vertical disc loading mechanism, the function of correcting the inclination of the disc 10J inserted into the disc pocket part 110 is provided to the disc clamper part x s o'd. Disc clamper flI! In addition to reducing the necessary pressing force by a considerable amount and contributing to the miniaturization, weight reduction, and simplification of the structure, it is also possible to prevent damage to the disk.

This is because the rear end surface of the clamper 126 is parallel to the surface of the turntable 161 immediately before the clamper 126 of the disk clamper part 180 presses the disk 101 inserted into the disk pocket wheel toward the turntable 161. This is achieved by adding a clamper control mechanism to the above-mentioned vertical loading mechanism.

The third point is that in the above-mentioned vertical disc loading mechanism &:, the disc pocket 91rDC is provided with a function of centering the disc inserted into the disc pocket part 1113, thus achieving the second point mentioned above. The point is that the same effect as in the case of 6 can be further promoted.

This means that the center hole of the disk 101 inserted into the disk pocket IL-9 is at least immediately before the center hole of the disk 101 is fitted with the guide 161B of the turntable 161 until the center hole of the disk 101 is fitted with the guide 161B of the turntable 161. The first position supporting the disc 101 so that it is at the same height as the center and the center hole of the disc log are the guides 161 of the turntable 161.
The disk support control mechanism f'J has a second position where it separates from the disk 1' (11) in a state where the fitting is completed to the disk 1'.
This is realized by adding '5 to the above-mentioned vertical loading mechanism.

The fourth point is that when the above-mentioned vertical disc loading mechanism≦;, when the clamper 116 of the disc clamper part 18B presses the disc 101 inserted into the disc pocket part 1ξ linearly toward the turntable 161, the clamper 1j- After the guide 161 & of the turntable 161 are fitted together, the clamper 126 presses the disk onto the turntable 161, and the disk I
OJ l: Part of the disk clamper has a function to control the clamping timing for the tea: 1 elm as described above. One point is that the same effect as in the case of two points can be achieved.

And this disk ioI is turntable 161
Guide 161! After fitting the clamper 12C
The clamper control mechanism 116, which applies a predetermined pressing force in the direction of the turntable 161 to the
This is realized by adding the vertical loading mechanism 1 described above.

The first point is that in the above-mentioned vertical disc loading mechanism, a sensor By providing this, the presence or absence of the disc can be detected before the disc 1111 is loaded into a predetermined driving position, that is, the turntable section.

And in this case, Disc Pocket @pr.

If the mounting position of the disk sensor 159 is set at the bottom of the disk pocket @tlo and slightly above the outermost circumference of the disk 1.01, the disk 101
It is also possible to determine the improper insertion state of the
(see figure).

Next 6: Various features I: of the disc pocket portion 110 in the vertical disc loading mechanism 100 (=) as described above will be explained.

The first point is that the disc pocket atto into which the disc 101 is inserted is inserted into the turntable 16 when the disc is inserted.
1, and the disk 101 is moved from the first position to the turntable 161 (
Two discs 10 loaded on the turntable
1 is configured to have a second position that allows it to rotate within 170% of the disc pocket, so that the overall configuration of the vertical disc loading mechanism can be made organic and rational. The following points can be mentioned.

The second point is that the opening for inserting the disc in the disc pocket J 70 is made narrower on the peripheral edge side of the disc XOX, and in the center of the disc 101, the signal surface of the 6th disc is damaged when the disc is inserted. (Figure 17 (al # (
b) I (C1 reference #l@).

The third point is when inserting a disc 6; turntable 1t
The first position moved to a curved surface more than jl and when loading a disk 6; The turntable 161 moved from the first position
The disc pocket part rya is rotatably supported with the upper part of the back surface of the disc pocket part rya as a fulcrum and takes a second position in which the disc 101 can be loaded. , and by providing a cover 102 that stands upright above the back surface of the disk pocket U at the second position, a space for grasping is formed behind the upper end of the disk 101 when the disk is inserted, and the disk can be inserted and removed. In this case, it would be possible to fix the cover in a tilted position from beginning to end, but in that case, it would not be possible to avoid the disc playback pickup located at the rear of the disc pocket. This causes an inconvenient situation in which the cover hits the cover.

Further, by providing the rotatable cover 102, there is an advantage that the size of the entire device can be made as small as possible.

The fourth point is the holder-1 of the disc pocket part 110.
Turntable introduction hole 10!5m and pickup introduction hole 10! which are connected to the back of 0Ii and shaped. In order to prevent the disk 101 from being incorrectly inserted into the ib section, as shown in FIG.
Upper and lower connecting parts of double entry holes 1068.101b - 2 guides with claw-like protruding pieces tilted backwards on the lower side
One example is the formation of 05c and 1aid. In other words,
The end of the disk is connected to the connecting part of both numbered holes 105m and 105b at the rear 6;
uaJC2 hits and is prevented from entering, and at the same time, it slides down inside C: of the disc pocket portion 1fu. Note that the guide may be formed on a substrate (not shown) provided at the rear of the holder 10M.

The fifth point is that the upper end of the front holder 106.119 constituting the disc pocket part UjO is at least connected to the optical axis (LJ height This is the same height as the center of the turntable 161) By extending it to a higher position,
Safety measures against the human body (Special I:
In the case of laser light sources, there are important points to be taken (I: Important) (see Figure 19).

It is assumed that this is also secured when the disk socket hWAs-to is opened. Furthermore, it is effective to make the upper end portions of the front holders 106 and 119 opaque.

Next, the disk drive and playback mechanism! To explain the details, as shown in FIGS. 20 and 21, ζ: The disc drive and playback mechanism section Z-On is the aforementioned disc loading mechanism f! I+110 disc blur 7toi
U] is located at the rear &= and is incorporated into the chassis 114.

Here, to briefly describe the outline of the disk drive and playback mechanism 1BjJLG-, it is the disk drive section z
10 and a disc playback mechanism @1111, the former being the aforementioned disc loading mechanism part 11.
It consists of a turntable 161 on which the disk 1-01 is loaded into the driving position by 20, and a motor j6g directly connected to the rear of the turntable 1151, which drives the disk 101 at a predetermined rotational speed of the CLV system. It is something.

The latter also includes an optical pickup I'U for reproducing a disk driven at a predetermined rotational speed as described above, and the pickup PU in a linear tracking direction from the inner circumference to the outer circumference l: in the radial direction of the disk. There is no pickup feeding mechanism 211 that moves the pickup.

In this case, the turntable s6j and the pickup PU form a holder tut that constitutes a disc pocket part.
s Each introduction hole 1ain formed on the back surface, 1 in 101b;
The introduction and exposure is as described above.

The pickup feed mechanism jjj is mounted on the mounting board 222 with three

As a result, the pickup PU is configured to send signals in a linear tracking manner along the signal surface of the disc driven at a predetermined rotational speed, and in the process optically reproduces each track on the disc. :Become.

Next 1; Disk drive and playback mechanism 52 as described above
The pickup feeding mechanism 211 section in 00 (=various features provided will be explained.

The first point is to eliminate uneven feeding due to play in the threaded portion between the feed base 211 and the feed screw 131, and to
One point is that it allows U to be sent smoothly.

And this is as shown in FIG.
112 formed #! Inside the spring 214, this spring 114 is supported by the stopper screw f J # on the feed base 211 with the pin 215.
This is achieved by pressing in the opposite direction to the feeding direction (rotation).
(As shown in C: This is because the pickup feed base 111 and the feed screws JJJZ are always in contact with each other without any play in the feeding direction (rotation).

The second point is that the position of the pickup PU can be displayed easily and favorably to the outside.

As shown in Fig. 24, this corresponds to
The tip α of the L-shaped arm 211 extending upward in the U (also in the pickup feeder 231): For example, a triangular light emitting diode or a simple pointer aSS is attached, and this light emitting diode or pointer j-JII is connected to the As shown in C2, a slit-shaped conductor 11- is formed above the disk pocket part sre when assembled into the cabinet 10.
The position of the pickup PU with respect to the disk 1016 can be directly displayed on the outside SC.This invention is limited to the second embodiment described above and illustrated. It goes without saying that various modifications and applications can be made without departing from the gist of the invention.

Therefore, according to the above-detailed view up to this invention, it is possible to use a special disk record playback device tC2 that drives a disk in a vertical position, which has a simple structure and is reliable. It becomes possible to provide an extremely good disk loading mechanism that is capable of loading the disk.
