Conventional structure and problems Conventionally, in high-density recording devices such as video discs, it has been necessary to manually play a disc in a cylindrical disc case, as disclosed in Japanese Patent Application Laid-open No. 111158/1983. There are many playback devices that use a so-called semi-automatic loading method, in which the device is inserted deep into the device and the empty case is manually removed. However, with this type of semi-automatic loading method, when inserting and removing the case manually, the case must be moved back and forth significantly, and the loading mechanism does not function perfectly to withstand harsh use by the user. There were various problems such as the difficulty in configuring the system.

Therefore, we proposed a device that allows the disc to be automatically removed from the case by simply inserting the disc case slightly into the playback device body. However, in this case, after loading the recording medium into the playback bag π, The empty case had to be removed from the recycling device and stored, so there was a problem that it could not be called a completely automatic bag bag.

Purpose of the Invention This invention enables the user to automatically take out the recording medium from the case by simply inserting the case slightly into the main body of the playback device, and then automatically store the empty case. To provide a recording disc reproducing device which does not require taking out an empty case from a reproducing device main body and storing it.

Composition of the Invention The recording disk reproducing apparatus of the present invention includes a case body which has a storage space capable of storing a daily amount of recording medium therein and has an opening at one end for taking out the recording medium, and a case body which has an opening for taking out the recording medium at one end; A recording disc playback device using a disc case comprising a lid that removably engages with the opening of the case body, the engagement substantially fixing the disc case body in a fixed position with respect to the playback device body. means for pulling the recording medium housed in the disc case into the playback apparatus main body together with the lid after the engaging means substantially fixes the disc case main body; and a transfer means for transferring the engagement means and moving the disc case main body, which is substantially fixed to the engagement means, into the playback apparatus main body.

Because of this configuration, simply by slightly inserting the disc case into the main body of the playback device, the recording medium is automatically removed from the case, and then the empty case can be automatically stored, allowing the user to remove the empty case. There is no need to remove it from the playback device and store it.

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

The first state is the "roof/disc holding state".

This is a state in which the lid 3 is completely closed and the disc 6 is clamped as shown in FIG. 7(A). In this state, the sliding member 1
02 is the 0M hanging g13 material 99. which is in the position closest to the right side of the figure (in the direction of arrow Y2) among the three states. 100
Hakam? s113. 114 yo-y and driven end 115,
116 are guided respectively, M
It is located in a position that regulates 3.

The temporary spring 94 is in contact with M3 as shown in the figure, and the zero rotation member 101, which is biasing M3 forward (in the direction of arrow X1), is in contact with M3 at contact '5101c. The lower clamp arm 96 is in a state of clamping the group guard 33 of the disk 6 as shown in FIG. 7 CB). In this state, the claw 95a of the upper clamp arm 95 and the contact end 95a of the lower clamp arm 96 are in a position to contact the group guard 33. In addition, as shown in FIG. 10 CB), the contact end 96a contacts the wedge-shaped portion 102c, and the sliding member 102 is urged to the right in the figure (in the direction of arrow Y1) by the urging force of the spring 110. As a result, the lower clamp arm 96 is as shown in FIG.
) is biased in the direction of arrow 98b, and the group guard 33
is held in between.

The second state is "I holding state gJ. This is shown in Fig. 8 (
As shown in A), the M3 is not engaged and the disk 6 is not clamped. In this state, the sliding member 102 is in an intermediate position among the three states.

The lid retaining members 99, 100, the temporary spring 94, and the rotating member 101 are all in the same state as the "lid/disk holding state", and M3 is not engaged as shown in FIG. However, this situation! In this case, since the sliding member 102 has moved from the "lid/disc holding state" to the left side (Y direction) in the figure, the wedge-shaped part 10 is no longer present as shown in FIG. 10(B).
2c and the abutting end 96a are not in contact with each other. Therefore, the lower clamp arm 96 is moved as shown in FIG.
As shown in B), it opens in the direction of arrow 98a and is in a state in which the disc 6 is not clamped.

The third state is the "non-retention state", this state is the 9th state
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 (Y direction) of the three states. The lid stop members 99 and 100 are in an open state as shown in FIG. 9, with driven ends 115 and 116 guided by the cam grooves 113 and 114, respectively. The lower clamp arm 96 is open, as in the state shown in FIG. 8, and the zero-rotation member 101, which does not clamp the disk 6, is in the position shown in the figure, with the contact portion 101b and the sliding member 102 comes into contact with the protrusion 102b, and the sliding member 102 moves to the right side (in the figure) due to the urging force of the spring 110.
It is regulated so that it does not slide in the Y2 direction).

In this way, the disc holding mechanism 90 can take three states: "lid/disk holding state gJ, rU holding state" and "non-holding state". These three shapes 5 are all sliding members 1
It is regulated at the position in the sliding direction (Y, Y2 direction) of 02. In other words, by changing the position of the IB moving member 102 in the Y direction,
r Lid holding state”.

The disk holding mechanism 90 can be changed into three states including a "non-holding state". However, among the three states above, "
The "lid holding state" can be held when the sliding member 102 is regulated to the state shown in FIG. 8 by some means against the force of the spring 110.

The case engagement and expansion mechanism 60 will be explained in detail. 1st

Figures (A) to (C) are explanatory diagrams of the structure and operation of the case engaging and expanding mechanism 60.

Reference numeral 80 designates the first movable base of the case engagement and expansion mechanism, which is configured to be movable in the X, , transported by. Reference numeral 62 denotes an engaging member, which includes a bearing 63 and a pin 74 fixed to the second movable heir 80.
It is supported so that it can rotate freely up and down. Also, the spring 72 causes the engagement member 62 to move as shown by the arrow W1 in FIG. 11(B).
is biased in the direction of The expansion member 66 is provided at a position corresponding to the support member 61 as shown in the figure, and is supported by a bearing 67 fixed to the second movable base 80 so as to be vertically movable. The expanding member 66 has an arm 64 and an abutting end 68.
is formed. 65 is a slider, as shown in Fig. 11 (
As shown in C), it is slidably attached to the fixed base 80. The slider 65 has a long hole ssa, 6
5b are provided, and pins 71 and 70 are engaged with each of them, so that they slide linearly in the directions of arrows Y and Y2 in the figure. Furthermore, the slider 65 is restricted at its center by the abutting portion 63a of the bearing 63, as shown in FIG. 11(C), and is configured to flex only slightly downward. Further, the slider 65 is provided with two engaging portions 69, and with this configuration, the expanding member 66 is attached to the slider 65.
acts on the right side of the figure (in the direction of arrow Y2), thereby rotating in the direction of arrow ■2 in the figure, and also on the left side of the figure (in the direction of arrow Y1)
As a result, it rotates in the direction of arrow 1. Further, a spring 73 is applied between the slider 65 and the second movable base 80 as shown in the figure, and always urges the slider 65 to the right side (in the direction of arrow Y2) in the figure. Further, the slider 65 is provided with an abutting end 76 and a notch 65c. A case guide 75 serves to guide the case 2, and is fixed to the fixed base 80.

The above is the configuration of the case engaging and expanding mechanism 60. Next, how does this case engaging and expanding mechanism 60 expand the case 2 and engage it so as to substantially fix the case 2 to the second movable base? Explain whether it matches. When the case 2 is not inserted into the playback device, the case engagement and expansion mechanism 60 is operated as shown in FIG. 11 (A
) to (C). In other words, the notch 65 of the slider 65 and the engaging member 62 are in contact with each other, and the slider 6' is restricted to the state shown in the figure against the biasing force of the spring 73.

Therefore, the expansion member 66 is
).

The case 2 is inserted into the case expansion engagement mechanism 60 in this state through the insertion opening 51 of the playback device main body 50 and guided by the case guide 75.

FIGS. 13A to 13C show the process of inserting the case 2 into the case expansion mechanism 60.

FIG. 13(A) shows the case engaging/expanding mechanism 60 in the same state as FIGS. 11(A) to (C). When the case 2 is inserted into the case engaging and expanding mechanism 60 in this state in the direction of arrow X2 as shown in the figure while being guided by the case guide 75, the vicinity of the opening of the case 2 first comes into contact with the expanding member 66. , case 2 is expanded as shown in FIG. 13(B). Then, when the case 2 is further inserted, the contact end 62a of the engagement member 62 comes into contact with the open end of the case 2, and the engagement member 62 rotates in the W2 direction in the figure, as shown in FIG. ), the engagement end 62b of the engagement member 62 engages with the engagement hole 13 of the case 2. When this happens, the notch 65c of the slider 65 and the engaging member 62 are no longer in contact with each other, and the slider 65 moves once to the right (Y2 direction) by the biasing force of the spring 73 as shown in FIG. 12CB). In the state shown in FIG. 12(B), the expanding member 66 rotates in the V2 direction as shown in the figure, so that it does not interfere with the removal of the disk 6 from the case 2. In FIGS. 12(A) to 12(C), the state of the case 2 at this time, that is, the state of the expanded case 2, is shown by dashed lines. In this state, the engaging member 62 is regulated by the slider 65 so as not to rotate in the W1 direction as shown in FIG. 12(B).
5 by some means to the left side (Y,
direction), the slider 65 moves in the direction of arrow Y1, and the notch 65c moves into the engagement member 6 as shown in FIG.
When the engagement member 62 reaches the position 2, the engagement member 62 rotates in the direction of the arrow W1 due to the biasing force of the spring 72, and engages the engagement hole 13 of the case 2.
The engagement between the engagement member 62 and the engagement member 62 is released.

As described above, the case engaging and expanding mechanism 60 of this embodiment has a means for expanding the case 2 as well as a means for engaging the case 2, and moreover, by mounting the slider 65, the case 2 can be easily expanded. It is possible to release the engagement with the

Further, in this embodiment, as shown in FIGS. 11 and 12, a microswitch 200 is placed at a position where it can come into contact with the slider 65.
Therefore, when the case 2 is inserted into the expansion mechanism 60, the case 2 is engaged, and the slider 65 is operated, the microswitch 200 can detect that the case 2 is expanded and engaged. The structure is as follows. In addition, when the engagement member 62 engages the case 2, the movement of the engagement member 62 causes the slider 65 to
Since the case 2 is L-shaped, the case 2 does not easily come off and remains substantially fixed to the second movable base 80.

Further, the microswitch 200 detects whether or not the case 2 is engaged with the engagement member 62, and a lamp 500 serves as a notification means to notify this detection state.
(FIG. 5) is provided on the front of the playback device main body 50.

Therefore, the user can easily check whether the case 2 is engaged or not. The lamp 500 is connected to remain lit while the engagement member 62 is in the engaged state. Note that a buzzer may be used as this notification means, and in the case of a buzzer, it is made to sound when the state changes from the engaged state to the non-engaged state.

At this time, since the cam groove diameter 12 is smaller than 11, the lever 16
2 moves in the B2 direction. The slider 65 is the stopper 41
Since it is locked by 0, it does not move, and only the lever 162 moves by force q. Further rotation of the cam 6 results in the state shown in FIG. 16(D). When the cam 161 rotates further from FIG. 16(C), the interlocking member 404 moves to the 16th
As shown in Figure (D), the lever 162 is located at the branch point between the cam paths 405a and 405c, and the lever 162 is urged to rotate in the B1 direction by the spring 163, and in this state, the abutment member 76 is engaged. It is separated from the pin 169, and as shown in FIG. 16(D), the engagement pin 169 is in a state where it can further rotate in the B1 direction. Therefore, the interlocking member 404 is urged into contact with the inner wall surface of the cam path 405a by the coil spring 163, and when the cam 161 rotates in the A2 direction in this state, the interlocking member 404 enters the cam path 405a. When the cam 161 further rotates, the lever 162 moves in the B1 direction shown in FIG. 14, and the lever 168 moves in the B1 direction. By moving the lever 162 in the B1 direction, 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 (14-shaped rock).

Operation Next, how the entire reproduction WiIF according to this embodiment operates with the above configuration will be explained step by step.

Figures 17 to 22, and Figure 23 (A).

24(B) and FIGS. 24(A) to 24(C) are all schematic explanatory diagrams showing how the operations of each part of the reproducing apparatus are performed in conjunction with each other.

First, FIG. 17 shows the state before the case 2 is inserted into the main body 50 of the playback device. 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 above-mentioned “non-holding state”.
Further, the support 180 is in a downward position as shown in FIG. 23(A).

Next, the case 2 passes through the insertion opening 51 and moves to the guide 52°53.
When the case 2 is guided and inserted into the case engaging and expanding mechanism 60, the opening of the case 2 is expanded by the expanding member 66,
In this state, the engagement member 62 engages the engagement hole 13 and is substantially fixed to the second movable base 80 .

Next, in this state, the microswitch 20 shown in FIG.
0 is detected, the motor 114 operates, and the belt 111 is driven to move the disk holding mechanism 90 to the front (in the figure).

Then, as shown in FIG.
contact, the restriction of the sliding member 102 is released, the sliding member 402 slides to the right (arrow Y2 direction), and the disc holding mechanism 90 enters the "lid/disk holding state" as described above.1 : When , the contact portion 102a of the sliding member 102 contacts the microswitch 201, and the disc holding mechanism 9
0 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 90 begins to be moved backward in the figure (in the X2 direction). At this time, the roller 103 provided on the sliding member 102
However, since the reversing lever 190 can rotate in the direction of arrow R2 in FIG. There isn't.

Next, Figure 19 shows the state during the transfer.
As shown in the figure, the lid 3 and the disk 6 are held by a disk holding mechanism 90 and pulled out from the case 2. Now, when the disk 6 is pulled out halfway as shown in this figure, the support 180 rises as shown in FIG. 23(B) and holds the group guard 33 of the disk 6. At this time, support 1
80 only touches the group guard 33, so it does not damage the signal surface of the disc 6.

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

Even in this state, the support 180 is configured as shown in the figure so as to hold the group guard 33 of the disk 6.

Next, the center mounting ring 133 is attached to the cam unit 160.
It rises by the action of , and holds the center of the disk 6.

FIG. 24(A) is a side view of this state. Next, as shown in FIG. 24(B), the support 180 is lowered by the operation of the cam unit 160. Next, when the disk holding mechanism 90 is further moved backward (in the X2 direction), the roller 103 provided on the IN moving member 102 of the disk holding mechanism 90 and the slope of the contact member 43 come into contact with each other.
The sliding member 102 works to the left (Y direction) and becomes the above-mentioned "lid holding state", that is, the disc 6 is not held by the disc holding mechanism 90, and this is the 21st state IG.
This is the state shown in the figure. In this state, the disk 6 is held by the mounting ring 133 in the center as shown in FIG. 24(C). Thereafter, when the mounting ring 133 is lowered by the operation of the cam unit 160, the disc 6 is mounted on the turntable 130.

Next, the motor 803 operates to move the guide 800 fixed to the second movable head 80 in the direction of the arrow X2, and pull the case 2 into the playback device main body 50 as shown in FIG. 21fa1. Most of case 2 is 'A'
Since the empty case is housed in the H, the empty case can be recycled without taking the trouble of removing it from the recycling surface main body 50. That is, in this state, the turntable 130 rotates, and the pickup unit 120 performs reproduction.

When the regeneration is completed, the case 2 returns to the state shown in FIG. 21 by the operation of the motor 803. This time cam unit 16
0 operates and the v1 position ring 133 rises, resulting in the state shown in FIG. 24(C).

Next, the motor 114 drives the heald 111, and this time it holds the disc. I! 90 is forward (arrow X1 direction)
The state is transferred to the state shown in FIG. 24(B). Then, the support 180 is raised by the operation of the cam unit 160, resulting in the state shown in FIG. 24(A). after this,'! !
The device ring 133 is lowered by the operation of the cam unit 160, and the disc holding mechanism 90 moves forward (in the X1 direction) with the motor 114. belt 11
Transported by 1. In other words, the state shown in FIG. 20 shifts to the state shown in FIG. 19.

Furthermore, the disk clamping machine ill! 90 is forward (X, direction)
When the roller 1 provided on the single moving member 102 is transferred to
03 and the slope 190a of the reversing lever 190 come into contact with each other. At this time, since the reversing lever 190 is restricted from rotating to R1, the roller 103 climbs the slope 190a and the sliding member 102 moves to the left (Y).

direction) and enters the above-mentioned "non-retained state", and the lid 3 is pushed into the case 2 by the biasing force of the temporary spring 94 as shown in FIG.

Then, the motor 114 rotates in reverse again, and the disk holding mechanism 90 is moved rearward (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 60
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 50 with M3 engaged with the case 2.

In this way, the user attaches the case 2 to the playback device main body 50.
By just slightly inserting the disc 60, the disc 60 is automatically taken out from the case 2 and playback becomes possible, and the disc 6 is also automatically stored in the case 2. Therefore, it is convenient to use since 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 the user. Furthermore, most of the case 2 can be pulled into the main body 50 of the playback device and stored during playback, which is convenient because there is no need to store the empty case during playback.

The reproducing apparatus of this embodiment operates in this manner, and these operations can be controlled by, for example, a microcomputer. In other words, by sequentially operating the motor 114 that drives the disk holding mechanism 90, the motor 124 that drives the pickup unit 120, and the cam drive motor 165 using a microcombination unit and a normal control circuit. , the above operations can be performed.

In addition, the disk holding mechanism 90 may be configured as shown in FIG.
In order to stop at each position shown in FIG. 9, FIG. 20, FIG. 21, and FIG. 22, the microsinches 202 to 205 shown in FIG. It is detected that the contact plate 109 has contacted, and the motor 11
This is possible by programming to stop 4.

Effects of the Invention In the recording disc playback device of the present invention, when the user only slightly inserts the disc case into the main body of the playback device, the recording medium is automatically taken out from the case.
The empty case can be automatically stored in the playback device main body, and the user does not have to take out the empty case from the playback device main body and store it.
