Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording disk reproducing apparatus that automatically draws a disk-shaped recording medium into the reproducing apparatus and reproduces the medium.

Conventional technology Traditionally, in playback devices for high-density recording disks, such as video disks, a disk in a cylindrical disk case is manually inserted into the back of the playback device, as disclosed in Japanese Patent Application Laid-Open No. 111158. There are many playback devices that employ a so-called semi-automatic loading method, in which an empty case is manually removed.

However, in this semi-automatic loading method,
When inserting and removing cases manually, it is necessary to move the case back and forth significantly, and it is difficult to configure a loading mechanism that operates perfectly even under severe use by users. There were various problems.

Therefore, an attempt was made to create a playback device that would automatically take the disc out of the case and play it, simply by inserting the case a little bit by the user. Its configuration includes a clamping means for clamping the disc, and a three-base device for playing the clamping means and the disc.

Consider something that is equipped with a means of transportation within the facility.

However, in implementing this, there was a problem in supporting the disk during transportation. That is, when the disk is pulled out from the case body together with the lid by the lid JII, the stop means, and the transfer means, it is necessary to support the disk so that it does not fall if the entire disk is pulled out from the case body.

However, if a fixed support means is provided, the latching means will interfere with the support means at the beginning of the drawer, making it impossible to draw out the drawer smoothly. Therefore, we considered that the support means can take two states: a supported state and a non-supported state.

The above recording disk reproducing apparatus will be explained below with reference to the drawings. FIGS. 25(A) to 25(q) show the structure of a conventional recording disk reproducing apparatus, and FIG. 26 is a sectional view of a main part explaining its operation.

In FIGS. 25 and 26, 6o is a case expansion mechanism;
90 is a disc holding mechanism, 130 is a turn 7--full,
The support 180 is interlocked and driven by a cam unit and takes two states: a raised position and a lowered position. The disk holding means 9o is configured to transport the disk 6 in the direction of insertion and removal through the case expanded by the case expansion mechanism 60.

The operation of the recording disk reproducing apparatus configured as described above will be explained below.

First, the disc clamping means 90 enters the case body 2 expanded by the case expansion mechanism 6Q, clamps the disc 6, and pulls it out from the case body 2. During the transfer, the support 180 is interlocked by the cam unit 160. driven,
The state shown in FIG. 26B changes from the human state shown in FIG. 26 to the state shown in FIG. 26B, in which the disk 6 being transferred is supported.

Problems to be Solved by the Invention However, using a supporting means with such a configuration only complicates the mechanism, and when the supporting means moves from the unsupported state to the supported state, the recording surface of the disk There was a risk of damaging the recording surface.

Therefore, the present invention is designed to prevent the supporting means from damaging the recording surface of the disk even if five vanes of vibration are applied to the moving disk.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide a slope between the case engaging means and the turntable to guide the disk being transferred. .

Effects The effects of this technical means are as follows. Suwachi,
By providing a slope from the insertion opening to below the disc mounting surface of the turntable, the disc is supported between the disc case and the turntable mounting surface when the disc is inserted or removed by the latching means and the transfer means. It is something that can be done.

As a result, the support moves closer to the recording surface and is stronger, so even if vibrations are applied to the playback device during disk transfer, the autoloading player can reliably transfer the disk without damaging the recording surface of the disk. can be provided.

Embodiments Examples of the present invention are shown in FIGS. 1 to 3 and 8 to 24. FIGS. 4 to 7 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. First, its configuration will be explained.

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

The first state is 1-lid/disc holding state.

This is a state in which the lid 3 is closed and the disc 6 is clamped as shown in FIG. 7(A). In this state, the sliding member 10
2 is located closest to the right in the figure (in the direction of arrow Y2) among the three states. The stopper for the lid 991100 is the cam groove 1
The driven ends 115 and 116 are guided by the guides 13 and 114, respectively, so that the lid 3 is in a restricted position as shown in the figure. The leaf spring 94 is in contact with the lid 3 as shown in the figure, and the lid 3 is biased forward (in the direction of arrow X1). The rotating part 101 is in a state of being in contact with the abutting 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, the claw 95a of the upper clamp arm 96 and the contact end 96a of the lower clamp arm 96 are in a position to contact the group guard 33. +, T, J in FIG.
Due to the old force of 0, the sliding member 102 moves to the right side in the figure (arrow Y
As a result, the lower clamp arm 96 is biased in the direction of arrow 98b in FIG. 7(B) and clamps the group guard 33.

The second state is a 1-difference holding state. This is 17

are not in contact. Therefore, the lower clamp arm 96 is
Due to the biasing force of the spring 98, it is opened in the direction of the arrow 98a in FIG. 8(B), and the disc 6 is not clamped.

The third state is a "non-retention state". This state is the 9th
As shown in the figure, the lid 3d is completely closed, and the disc 6 is in a state where it is fully clamped. The sliding member 102 is in the position closest to the left (y+ direction) in the figure among the three states. The latch portions 99 and 10Q are connected to the 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 a state similar to that shown in FIG. 8, in that it is open and does not clamp the disk 6. The rotating part (3101 is in the position shown in the figure, the contact part 101b and the protrusion 102b on the sliding part side 102 are in contact with each other, and the sliding part (/11o2) is moved to the right side of the figure (Y2 (direction) to prevent it from sliding.

In this way, the disc holding mechanism 90 has three states: "lid/disk holding state", "lid 1''A) waiting state-1, and "non-holding state". These three states d are all regulated by the position of the sliding member 102 in the sliding direction (Yl, Y2 direction). ') Set the position of the sliding member 102 to Yl.
, "Lid/disc holding state" and "differential holding state" by changing in the Y2 direction.

The disk holding mechanism 90 can be changed into three states including a "non-holding state". However, among the three states below,
In the "differential holding state", the sliding part; iA'102 is connected to the spring 110
The case expansion mechanism 60, which can be held in the state shown in FIG. 8 by some means against the force of FIG. 8, will be explained in detail.

Fig. 11 (A) - (C'), Fig. 12 (A) - (c)
, FIGS. 13(A) to 13(C) are explanatory diagrams of the structure and operation of the case expansion mechanism 60. Reference numeral 80 denotes a fixed base of the case expansion mechanism, which is fixed to the chassis 40 of the playback device and is located near the insertion opening 51 as described above.

The support member 61i is fixed to the fixed base 8o.

62d: The engaging portion is supported by a bearing 63 and a pin 74 fixed to the fixed base 80 so as to be able to move up and down. Unfortunately, the spring 72 causes the engaging member 62 to move as shown in FIG.
B) is forced in the direction of arrow W1. Expanding member 66
is provided at a position corresponding to the support portion 61 as shown in the figure,
It is supported by a bearing 67 fixed to a fixed base 80 so as to be vertically movable. The arm 6 is attached to the expanded part 4'A66.
4 and an abutting end 68 are formed. Reference numeral 65 is a slider, and as shown in FIG. 11(G), the slider 65 is slidably mounted on the fixed base 80. The slider 65 is provided with elongated holes 66ia and 65b, into which the pins 1 and 70 engage, respectively, and are configured to slide linearly in the directions of arrows Y and Y2 in the figure. 1/ζ, the slider 6 as shown in FIG. 11(C) is
5 is configured such that ``1 and 2 parts are restricted, and there is only a slight deflection in 'T: (l!l.

'-1: The slider 65 is provided with two retaining parts 69, and with this configuration, the expanded part 1A66 is moved to the right side of the figure (in the direction of the arrow Y2), as indicated by the arrow v2 in the figure. By rotating in the direction of the arrow v1 and working to the left side of the ox-da diagram (in the direction of the arrow Y1), it rotates in the direction of the arrow v1. 1 between the slider 65 and the fixed base 80.
As shown in the figure, a spring 73 is applied to keep the slider 65 always on the right side (in the direction of arrow 11Y2) in the figure. 1
However, 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 8o.

The above is the configuration of the case expansion mechanism 60. Next, we will explain how the case expansion mechanism 60 expands the case 2 and engages with the vane 21 to substantially fix the case 2 to the playback device. explain. When the case 2 is not inserted into the playback device, the case expansion mechanism 60 is operated as shown in FIG.
It is in the state shown in A) to (C). In other words, slider 6
The notch 65 of 5 and the engaging member 62 abut, and the slider 65
is regulated to the state shown in the figure against the old force of the spring 73. Therefore, the expansion portion profit 66 is as shown in FIG. 11(B), (
It is said that it is regulated in the position shown in C). The case 2 is inserted into the case expanding mechanism 60 in this state through the insertion opening 51 of the playback device main body 50 and guided by the case guide l-' 75.

13A to 13G show the process of inserting the case 2 into the case expansion mechanism 60. Figure 13 (A
) shows the case expansion mechanism 60 in the same state as in FIGS. 11(A) to 11(C). When the case 2 is inserted into the case expansion mechanism 60 in this state while being guided by the case guide 75 in the direction of arrow X2 as shown in the figure, first the expansion member 6
The vicinity of the opening of case 2 is in contact with 6, and case 2 is in contact with the 13th
It is expanded as shown in Figure (B). Then, case 2
When inserted 22 , the contact end 62a of the engagement member 62 contacts the open end of the case 2, and the engagement portion A62 rotates in the W2 direction in the figure, as shown in FIG. 13(G). The engaging end 6 of the engaging member 62 as shown in FIG.
2b engages with the engagement hole 13 of the case 2. With this,
The notch 65C of the slider 65 and the engaging member 62 are no longer in contact with each other, and the slider 65 (1") slides to the right (Y2 direction) by the old force of the 1 spring 73 as shown in FIG. 12(B). In the state shown in FIG. 12(B), the expanding member 66 rotates in the 2-direction as shown in the figure, and the disc 6 from the case 2
It is in such a state that it is hindering the removal of the item. 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 a chain line.

In this state, the retaining member 62 is restricted by the slider 65 so as not to rotate in the W1 direction as shown in FIG. 12(B). Next, for example, if the abutting end 76 of the slider 65 is moved to the left side of the figure (y+ force direction), the slider 66 will move in the direction of arrow Y1, and the notch 650 will open as shown in FIG. When the engaging member 62 reaches the position, the engaging member 62 rotates in the direction of the arrow W1 due to the force of the spring 7223 l combination d
, is released.

As described above, the case expanding mechanism 60 of this embodiment has a means for expanding the case 2 as well as a means for engaging the case 72, and moreover, by not moving the slider 65, it is possible to easily engage the case 2. It is possible to cancel the connection.

In this example, as shown in Figures 111 and 12,
The microswitch 20 is placed in a position where it can come into contact with the slider 65.
0, when the case 2 is inserted into the expansion mechanism 60, the case 2 is engaged, and the slider 66 is operated, the microswitch 200 is expanded and engaged. The structure is such that it is possible to detect When the case 2 is engaged with the engagement member 62,
As mentioned above, since the movement of the retaining portion 62 is restricted by the slider 65, the case 2d° will not easily come off and will be substantially fixed to the playback device 60.'7. The state will be as follows.

The micro-sinch 200 detects whether or not the case 2 is engaged with the engaging part 62, but the lamp 550 serves as a notification means to notify this detection state.
(FIG. 2) is provided on the front of the playback device main body 50. Therefore, the user can easily check whether or not the case 22 is engaged. The lamp 550 is connected so that the lamp 550 continues to be lit when the locking section 62 is in the locking state. Note that a buzzer may be used as this notification means. In the case of a buzzer, when the state shifts from the engaged state to the disengaged state, Kl! I'll try to do it.

Next, we will focus on the operations of the cam 161 and the lever 162, and the operations of the cam unit I/160 in Figs. 8 and 16.
This will be explained using figures. FIG. 14 shows a state in which the case 2 is not inserted into the playback device, and the corresponding cam 161
The motion part 404 is in the state shown in FIG. 16(A). When the case 2 is inserted, the slider 65 moves and the contact portion 76 moves the engagement pin 169, resulting in the state shown in FIG. 9. The slider 65 is stopped by a stopper 410, as shown in FIG. 14(B), and never moves. This state is the state shown in FIG. 16(B). 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 the t1 state in Fig. 16 (hereinafter,
(The state is indicated by t4 in the timing chart of FIG. 16).

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 60, the locking state of the slider 66 is released and the case 2 is expanded as described above. It is substantially fixed to the opening mechanism (t6 state). This is the state shown in FIG. 12 and FIG. 16(B). The microswitch 200 detects this state, and the motor 165 is energized so that the cam 161 rotates in the direction A, which is the opposite direction to that described above. When the cam 161 rotates, the lever 167 is first pulled in the B2 direction in FIG.
The lifting mechanism 134 rises and supports the disk 6 above the turntable 130.

When the cam 161 further rotates, the lever 167 moves in the B1 direction, lowering the elevating mechanism 134 (tlo state). Thereafter, the disk 6 is recovered into the case 2 by the disk holding mechanism 9°.

When the cam 161 further rotates, the interlocking member 404 faces the branching member 403b and enters the cam path 405b as described above, resulting in the state shown in FIG. 16(A), and the lever 162 moves the slider 65. let case 2
The substantially fixed state of is released, and the state shown in FIG. 8 and FIG. 16(A) is achieved.

At this time, the contact portion 102a of the sliding member 102 contacts the microswitch 201, and it is detected that the disc holding mechanism 9o is in the "lid/disc holding state" at this position. Then, the motor 114 rotates in the reverse direction, and the disk holder starts to be moved backward (in the X2 direction) through the shallow groove 90ν in FIG. 1. At this time, the roller 103 provided on the sliding portion 4J' 102 comes into contact with the remaining surface 190b of the reversing lever 19Q, but since the reversing lever 190 can rotate in the direction of arrow R2 in FIG. Just by rotating 190,
There is no problem in transferring the disk holding mechanism 90.

Next, FIG. 19 shows the state during the transfer.

As shown in the figure, the lid 3 and the lid 6i are held together by the J-task holding mechanism 9.

Further, when the disk holding mechanism 9o is moved forward (in the Since the roller 103 climbs the rest 190a and the sliding part 102 moves to the left (in the y+force direction),
The lid 3 is placed in the non-retained state as shown in Figure 22.
The old force of the leaf spring 94 pushes it inside.

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 160 parts of the recam unit are operated, and the engaging part ("6") of the case 2 and the case expansion mechanism 60 is operated.

The case 2 can be taken out from the playback device main body 50.

In this way, the user attaches the case 2 to the playback device main body 50.
By just slightly inserting the disc 6, the disc 6 is automatically taken out from the case 2 and playback becomes possible, and the disc 6 is 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 an unscrupulous user. The advantage is that only the disc 6 and lid 3 are pulled in without pulling the entire case 2 into the playback device main body 50, so the playback device main body 60 can be made thinner than when the entire case 2 is pulled in. be.

Although the reproducing apparatus of this embodiment operates, these operations can be controlled by, for example, a personal computer such as a personal computer, computer, computer, etc. Tsutsusu,
The above operation is achieved by sequentially operating the motor 114 that drives the disk holding mechanism 90, the motor 124 that drives the arm nozzing 120, and the cam drive motor 165 using a microcombi coater and a normal control circuit. can be made to
