Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a disk-shaped recording medium (hereinafter referred to as a disk).
This invention relates to a recording disk reproducing apparatus that automatically draws a disc into a reproducing apparatus and performs reproduction.

Conventional technology Conventionally, in playback devices for high-density recording discs, such as video discs, it has been necessary to manually move the disc in a cylindrical disk case to the back of the playback device, as disclosed in Japanese Patent Application Laid-Open No. 111158/1983. There are many playback devices that employ a so-called semi-automatic loading method, in which a player is inserted and an empty case is manually removed. However, with this semi-automatic loading method, when manually inserting and removing the case, it is necessary to move the case back and forth a lot, and the case does not function perfectly even under severe use by the user. There were various problems such as difficulty in configuring the loading mechanism. Therefore, we attempted to create a playback device that would automatically take the disc out of the case and play it, just by slightly inserting the case into the case. We have considered a structure that includes a clamping means for clamping the disc, and a transporting means for transporting the clamping means and the disc within the playback apparatus.

A conventional example will be described below with reference to the drawings.

FIGS. 27(5) and 27(B) show a conventional recording disk reproducing apparatus. FIGS. 28 and 29 are explanatory diagrams of a conventional clamping mechanism. 6Q is a case expansion mechanism, 90 is a disc holding mechanism, 103 is a roller, 130 is a tar/tiful, 16o is a cam unit, and 190 is a reversing lever.

The disc holding mechanism 90 is configured to clamp the disc inside the case expanded by the case opening mechanism 60 and transport the disc from inside the case in the direction of taking it in and out of the main body of the playback apparatus. FIG. 28 is a diagram showing the disc in the case being clamped by the clamping means. The force of the clamping means to clamp the disk is generated by a spring force or the like. The roller 103 moves depending on whether the disc is clamped or not clamped by the clamping means.

Problems to be Solved by the Invention However, when a clamping means having such a configuration is used, since a force for clamping the disc is generated by a spring force, etc., there is a possibility that a disc clamping failure may occur due to a user's erroneous operation. . The state shown in FIG. 29(B) shows a state of poor clamping. That is, the position of the rollers is neither in a clamping state nor in a non-clamping state. In this state, since the reversing lever 190 prevents the roller 103 from moving forward, there is a risk that the clamping means cannot be moved from this position, which could lead to a "1-ding failure" problem.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide a regulating means for regulating the clamping means to a non-disk clamping state when the clamping means fails to clamp the disc. It is.

For production The effect of this technical means is as follows.

When the clamping means clamps the disc inside the case,
If a clamping failure occurs, the clamping means is regulated to a non-clamping state by the regulating means. 51, the clamping means is in a state where it can be clamped at that position.

As a result, even if the clamping means fails to grip the disc due to a user's erroneous operation, the clamping means moves in a non-disc clamping state, so the problem of disc clamping failure can be recovered without damaging the disc. We can provide an autoloading player.

Embodiments Examples of the present invention are shown in FIGS. 1, 2, and 8 to 26. 3 to 6 show the configurations of a disk and a disk case, respectively, which can be used in the recording disk reproducing apparatus according to this embodiment.

The operation of the disc holding mechanism 90 will be explained. The disk holding mechanism can take the following three states.

The first state is the "lid/disk holding state".

This is a state in which the lid 3 is closed and the disc 6 is clamped as shown in FIG. 7. In this state, the sliding member 102
is located closest to the right (in the direction of arrow Y2) in the figure among the three states. The latching member 99.100 is in the cam groove 11.
The driven ends 115 and 116 are guided by the guides 3 and 114, respectively, so that the lid 3 is in a restricted position as shown in the figure. The plate spring 94 is in contact with the lid 3 as shown in the figure, and is in a state where the lid 3 is urged forward (in the direction of arrow x1). Rotating member 1
01 is in a state of being in contact with the contact end 101c.

The lower clamp arm 96 is attached to the disc 6 as shown in FIG. 7(B).
The group guard 33 is in a state of being held in place.

In this state d, the claw 95a of the upper clamp arm 95 and the contact end 96a of the lower clamp arm 96 are in a position where they contact the group guard 33. As shown in FIG. 10(B), the contact end 96a contacts the wedge-shaped portion 102c, and the spring 110
The sliding member 102 moves to the right side in the figure (arrow Y1
As a result, the lower clamp arm 96 is urged in the direction of arrow 98b in FIG. 7(B) and clamps the group guard 33.

The second state is a "differential hold state". This is shown in Figure 8 (
The lid 3 is closed and the disc 6 is not clamped. In this state, the sliding member 102 is in an intermediate position among the three states. The latch members 99, 100, the leaf spring 94, and the rotating member 101 are all in the same state as the "lid/disk holding state", and the lid 3 is fixed to the latch 17 as shown in FIG. There is. However, in this state, since the sliding member 102 has moved to the left side (Y1 direction) in the figure from the "one lid/disc holding state", it is no longer in contact with the wedge-shaped part 102C, as shown in FIG. 10(B). The ends 96a are not in contact. Therefore, the lower clamp arm 96 is opened in the direction of the arrow 98a as shown in FIG. 8(B) by the biasing force of the spring 98, and is in a state in which it does not clamp the disk 6.

The third state is a "non-retention state." This state is the 9th
As shown in the figure, the lid 3 is not hooked and the disc 6 is not clamped. The sliding member 102 is in the position closest to the left side (in the direction of Yl) in the figure among the three states. The latching members 99 and 100 have driven ends 115 and 116, respectively.
are guided by the cam grooves 113 and 114 and are in an open state as shown in FIG. The lower clamp arm 96 is in the same state as in FIG. 8 and is open and does not clamp the disk 6. The rotating part 101 is in the position shown in the figure, and the contact part 1o1b and the protrusion 102b of the sliding member 102 are in contact with each other,
The sliding member 102 is prevented from sliding to the right (Y2 direction) in the drawing by the biasing force 18 .- of the spring 110.

In this way, the disc holding mechanism caold1 has three states: "lid/disc holding state", "differential holding state", and "non-holding state".
It can take two states. These three states are all regulated by the position of the sliding member 102 in the sliding direction (Yl, Y2 direction). By changing the position of the twisting sliding member 102 in the Yl and Y2 directions, the "lid/disk holding state" can be achieved.
, “differential retention state.”

It is possible to change the disk holding mechanism 9° to three states: non-holding state q.However, among the following three states,
The "differential holding state" is a state in which the sliding member 102 can be held in the state shown in FIG. 8 by resisting the force of the spring 110 and regulating it to the state shown in FIG.

As shown in FIG. 11 (q), the slider 66 is restricted at its center by the contact portion 63a of the bearings 3, and is configured so that there is only a slight amount of flexure on the lower side. 65 is provided with two retaining portions 69, and with this configuration, the expansion member 66 is rotated in the direction of arrow v2 in the figure by the slider 66 working to the right in the figure (in the direction of arrow Y2), and the expansion member 66 is rotated in the direction of arrow v2 in the figure. Left side of the figure (arrow Y1 direction)
It will rotate in the direction of arrow ■1 due to the action of and. As shown in the figure, a spring 73 is applied between the slider 65 and the fixed base 80, which always urges the slider 65 to the right (in the direction of arrow Y2) in the figure. 66 is provided with an abutting end 76 and a notch 65G. A case guide 75 has a recess 7 for guiding the case 2 and is fixed to a fixed base 80.

The engagement pin 169 is urged by the coil spring 163 to contact the contact member 76, and the interlocking member 404 is in a neutral state without contacting the inner wall surface of the cam groove 400. This state is state 11 in Fig. 16 (hereinafter referred to as state 16).
(The status is shown in the form of tx in the timing chart in the figure)
. The microswitch 200 detects this state, and the disc holding mechanism 90 grips the disc 6 and starts pulling it out from the case 2. The motor 166 is energized and the cam 1
61 is rotated 27 in the A2 direction shown in FIG. 14(B), and the levers 167 and 168 are moved in the B2 direction shown in FIG. 14(B) according to the timing chart of FIG. 15 mentioned above.
The support 18o and the elevating mechanism 134 align in a row to support the disk 6 above the turntable 130 (states t2 and t3). This state is the state shown in FIG. 16 (q). At this time, Since the cam groove diameter 2 is smaller than 2, the lever 162 moves in the P2 direction.The slider 66 is stopped by the stopper 410, so it does not move, and only the lever 162 moves.When the cam 6 further rotates, the lever 162 moves in the P2 direction. , the state shown in FIG. 16 p) is reached. Figure 16 (q
As the cam 161 further rotates, the interlocking member 404 moves between the cam paths 406a and 40 as shown in FIG.
5. Although the lever 162 is located at the branch point with the spring 1
63, and in this state, the contact portion 76 is separated from the retaining pin 169, and as shown in FIG.
It is in a state where it can be rotated in the l direction. Instead, the interlocking member 404 has a coil spring 163 on the inner wall surface of the cam path 405a.
When the cam 161 rotates in the A2 direction in the state of , the interlocking member 404 enters the cam path 405a. When the cam 161 further rotates, the lever 162 moves to the first position.
The lever 168 which has been turned in the P1 direction V'C shown in FIG. 4 moves in the B1 direction. By moving the lever 62 in the direction B1, the slider 65 is moved to the state shown in FIG. 14(A), and the state in which the engagement member 62 engages the case 2 is released (state t4). At the same time, the lever 168
The support 18o moves in the B1 direction shown in the figure and descends (state t4).

When the Camtro 1 further rotates, the lever 167 moves to the 14th position.
The disc 6 is moved in the B1 direction in the figure, the lowering mechanism 134 is lowered, and the disc 6 is placed on the turntable 130 (state t6). When the cam 161 further rotates, the state becomes t6,
When the position of the rotary switch (not shown) K is detected and the power to the motor 166 is turned off, the cam 161
stops (t6 state). This state is shown in Figure 14 (A).
and Fig. 16 (in which the cam 161 is 360
This means that it has rotated 0 times.

29 Pa After this, when the playback switch is turned on, playback starts.

After the playback is finished, the turntable 130 stops and becomes ready for removal, and when the case 2 is inserted into the case expansion mechanism 6o, the slider 65 is disengaged and the case 2 is expanded as described above. Almost fixed to the opening mechanism (
17 states). This is the state shown in FIGS. 9 and 16(B). Microsinch 200 detects this state,
The motor 16 is energized so that the cam 161 rotates in the A1 direction, which is the opposite direction to that described above. When the cam 161 rotates, the lever 167 is first pulled in the direction B2 in FIG.
Support above 0. The lever 168 is pulled, and the support 180 rises to support the disk 6 (state t9). When the cam 161 further rotates, the lever 167 moves to B.
move in one direction and lower the elevating mechanism 134 (t1o
situation). Thereafter, the disk 6 is recovered into the case 2 by the disk holding mechanism 90. During its operation, cam 16
1 rotates, the lever 168 moves in the B1 direction, and the
・\Port 180 goes down (tll state). Further, the slider 66 is moved, and the substantially fixed state of the case 2 is released, resulting in the state shown in FIGS. 8 and 16 (FIGS. 8 and 16).

If each state in Fig. 15 is simply set to 1, to is the standby state, tl is the case inserted state, t2 is the lift raised position, t3 is the support raised position, t3' is the start of slider movement, and t4 is the slider lock (case removed). ), t6 is the lift lowered position, t6 is the standby state, t7 is the case inserted state, t8 is the lift raised position, t9 is the support raised position, tl. indicates the lift lowered position, '11 indicates the support lowered position, and '12 indicates the slider lock (case detachment).

Next, the regulatory means will be explained. FIG. 25 is an explanatory diagram of the operation, and FIG. 26 is a flowchart for explaining the operation. The reversing lever 700 is provided with an abutting member 01. cam 1
61 is provided with a regulating member that engages with the contact portion 701 of the reversing lever 700 in the state shown in FIG. 26(B) (the state in which the reversing lever 700 is rotated). If the clamping operation of the clamping means is poor and the state shown in FIG. 26(B) occurs, follow the flowchart in FIG. When the cam is rotated, by stopping the cam in the state shown in FIG. 26 (q), the clamping means can recover from the trouble and move.

Next, how the entire reproducing apparatus according to this embodiment operates with the above configuration will be explained step by step.

FIG. 17 shows the state before the case 2 is inserted into the playback device main body 60 without being separated. At this time, the disc holding mechanism 90 is located slightly in front of the center of the turntable 130 as shown in the figure.

The disk holding mechanism 90 is in the aforementioned "non-holding state".

The boat 18Q is in a lower position as shown in Figure 23.

Next, the case 2 passes through the insertion port 61 and the guide 62°53
When it is guided by VrC and inserted into the case expansion mechanism 6o,
The opening of the case 2 is expanded by the expansion member 66, and in this state, the engagement hole 13 is engaged by the engagement member 62, and the case 2 is substantially fixed to the playback device main body 5o.

Next, in this state, the microsinch 20 shown in FIG.
0 is detected and the motor 114 is operated to drive the bell l-111, thereby moving the disk holding mechanism 9o forward in the figure (in the X1 direction).

Then, as shown in FIG.
contact, the restriction on the sliding member 102 is released, the sliding member 102 slides to the right (arrow Y2 direction), and the disc holding mechanism 90 returns to the "lid/disk holding state" as described above. At this time, the contact portion 102a of the sliding member f02 is still in contact with the microswitch 201, and the disc holding mechanism 9o
is detected to be in the "lid/disk holding state" at this position. Then, the motor 114 rotates in reverse, and the disk holding mechanism 9o begins to be moved backward (in the X2 direction) in the figure. At this time, the roller 103 provided on the sliding portion 102 contacts the slope 703a of the reversing lever 700, but since the reversing lever 700 can rotate in the direction of arrow R2 in FIG. Just by moving,
There is no problem in transferring the disk holding mechanism 90.

The above is a description of the operation in the state where the disk is held in place, but the operation when the holding mechanism 9Q is unable to hold the disk due to a user's erroneous operation or the like will be described.

If the disc is not held in the disc holding state even after several seconds have passed since the holding mechanism was moved forward, the microcomputer makes a judgment, rotates the cam 161, returns the reversing lever 700, and returns to the state shown in Fig. 26 (q). In this state, the clamping mechanism 90
The case is in the non-retention state J.Then, the holding mechanism 90 is moved rearward and the cam 161 is further rotated to release the case.This will allow you to escape from the trouble.

Next, FIG. 19 shows the state during the transfer. As shown in the figure, the lid 3 and the disc 6 are held by a disc holding mechanism 90 and pulled out from the case 2. Now,
When the disk 6 is pulled out halfway as shown in this figure,
As shown in FIG. 23(B), the port 180 is triggered and holds the group guard 33 of the disk 6. At this time,
Since the board 180 only touches the group guard 33, it is unlikely to damage the signal surface of the disc 6.

Further, when the disc holding mechanism 90 is moved rearward (X2 direction), the center boss 131 at the center of the turntable 130 and the center hole 34 of the disc 6 are
and come to approximately corresponding positions.

This state (also supported in C) 180 is configured as shown in the figure to hold the group guard 33 of the disk 6.

Next, the center mounting ring 133 is attached to the cam unit 160.
The disks 6 are placed in the upper row by this action, and the center portion of the disk 6 is held.

A diagram illustrating this state from the side is FIG. 24 (No. 8).

Next, as shown in FIG. 24(B), the support 180 is lowered 367 by the operation of the cam unit 160. Next, when the disk holding mechanism 90 is further moved rearward (X2 direction), the disk holding mechanism 90
The roller 103 provided on the sliding part A' 102 of 0 contacts the slope of the contact part 43, and the sliding member 102 moves to the left side (Y1
direction), resulting in the "differential holding state" mentioned above. Tsuguri,
The disk 6 is not held by the disk holding mechanism 90, which is the state shown in FIG. In this state, the disk 6 is held by the mounting ring 133 in the center as shown in FIG. It is placed on the table 130-. Next, the cam unit 160 performs operation 1 to release the engagement between the engaging member 62 of the case expanding mechanism 60 and the case 2, and the empty case 2 can be removed from the playback device.

In this state, the turntable 130 rotates, the arm housing 120 scans over the disk 6, and reproduction is performed. At this time, since the lid 3 is held from below by lid holding members 41 and 42 as shown in FIG. 21, it often hangs down and comes into contact with, for example, the arm housing 120 while driving.

When the playback is completed and the user inserts the empty case 2 into the playback device, the engaging member 6 of the case expansion mechanism 60
2 is engaged with the case 2, and the case 2 is connected to the playback device main body 60.
It is in a state where it is approximately fixed to . The micro spinch 2o○ detects this state in the same manner as described above, and this time the cam unit 160 operates], and the mounting ring 133 moves upward to the upper y1.
Figure 24 (becomes state q).

Next, the motor 114 drives the belt 111, and the disk holding mechanism 90 is now moved forward (in the direction of arrow X1), shifting to the state shown in FIG. 24(B).

Next, the boat 180 is raised by the operation of the cam unit 1-160, and becomes the state shown in FIG. 24 (8). Thereafter, the mounting ring 133 is lowered by the operation of the cam unino l-160, and the disc holding mechanism 90 moves forward (in the X1 direction) with the motor 114.
It is transported by belt 111. 3γ, -1 In other words, the state shown in FIG. 20 shifts to the state shown in FIG. 19.

When the disk holding mechanism 90 is further moved forward (in the Since the movement is restricted, the roller 103 climbs the slope 190a, and the sliding member 102 moves to the left (Y1 direction) to enter the above-mentioned "non-holding state", and as shown in FIG. is pushed into the case 2 by the biasing force of the leaf spring 94.

Then, the motor 114 rotates in reverse again, and the disk holding mechanism 90 is moved rearward (in the X2 direction) and returns to the position shown in FIG. 17. After this, the cam unit 160 also operates, and the engagement member 62 of the case 2 and the case expansion mechanism 6o
The case 2 is disengaged from the case 2, the disc 6 is stored in the case 2, and the case 2 can be taken out from the playback device main body 60 with the lid 3 engaged with the case 2.

In this way, the user can attach the 38 A to the playback device main body 6o.
.

By just slightly inserting the case 2, the disc 6 is automatically taken out from the case 2 and can be played, and the disc 6 is also automatically stored in the case 2. Therefore, it is convenient to use because there is no need to manually move the case 2 back and forth significantly, and reliable operation can be expected even under severe use by even the most demanding users.

Since only the disc 6 and the lid 3 are pulled in without pulling the entire case 2 into the playback device main body 6o, the advantage is that the playback device main body 50 can be made thinner than when the entire case 2 is pulled in. be.

The reproducing apparatus of this embodiment operates in this manner, and these operations can be controlled by, for example, a microcomputer. In other words, the disk holding mechanism 9 is controlled by a microcomputer and a normal control circuit.
0 and the arm housing 120.
The above operation can be performed by sequentially operating the motor 124 that drives the cam drive motor 124 and the cam drive motor 166.

39 ・＼ -Also, in order to stop and move the disk holding mechanism 90 at each position shown in FIGS. It is detected that the contact plate 109 held by the disk holding mechanism 90 is in contact with the microswitches 202 to 206 shown in 8, and the motor 1 is activated.
This is possible by programming to stop 14.

As described above, according to the present embodiment, the opening means for expanding the case, the holding and transferring means for holding and transferring the disc in the direction of putting it in and taking it out of the playback device, and the disk holding operation of the holding and transferring means are performed. If the disc is not fully clamped, a regulating means is provided to restrict the clamping transfer means to a non-clamping state, thereby avoiding the problem of disc clamping failure due to user's erroneous operation, etc., and safely automatically taking discs in and out of the case. It is something that can be done sensibly.

Effects of the Invention As described above, the present invention includes a clamping means for clamping a disc, a transporting means for transporting the disc in a direction in which the disc is taken in and out of a playback device, and a clamping means that is restricted to a non-clamping state. By providing a regulating means, even if the clamping means fails to clamp the disc due to user's erroneous operation, variations in the disc case, variations in the disc, etc., it is possible to recover from the trouble and return to normal condition again. It is possible to provide an autoloading player that can perform loading.
