Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the outer appearance of a disc reproducing apparatus according to an embodiment of the present invention, FIG. 2 is a perspective view showing a state in which a disc mounting table is pulled out from the disc reproducing apparatus, and FIG. 3 is this disc reproducing apparatus. It is an exploded view of an apparatus.

In these figures, reference numeral 1 denotes a cabinet of the disc reproducing apparatus. Reference numeral 2 denotes a table on which an optical disc is mounted. This table 2 can be inserted into the cabinet 1 in the direction of arrow A'and taken out in the direction of arrow A. The table 2 has a concave portion 3 on the upper surface thereof for accommodating an optical disc. Further, as shown in FIG. 2, the table 2 has notches 4 and 4 on the left and right sides thereof to allow insertion of a user's finger when setting and resetting the optical disc in the recess 3. Table 2
Includes a disk drive system including a turntable 5, an optical pickup 6, a printed circuit board 7 on which a drive circuit and the like are mounted, and the like.

Reference numeral 8 is a front panel attached to the front side of the table 2. The front panel 8 has an eject button 9 for inputting a signal for instructing to eject the table 2 from the cabinet 1, and a small hole 10 for allowing a wire or the like to be inserted from the outside when the lever 50 is operated.

On the other hand, as shown in FIG. 3, the cabinet 1 is divided into a pair of upper and lower cabinet parts 1.
It is composed of A and 1B. On both sides of cabinet 1,
A pair of guide members 11, 11 having guide rails for guiding the movement of the table 2 are attached. Locking members 12, 12 for fixing the table 2 at a predetermined position where the table 2 is discharged from the cabinet 1 are attached to one ends of the guide members 11, 11, respectively. A printed board 14 on which a connector 13 for connecting the disc reproducing apparatus to a computer and other circuits are mounted is fixed to the inner surface of the cabinet 1. The printed circuit board 14 and the printed circuit board 7 in the table 2 are connected to each other through a flexible cord 15 so that signals can be transmitted. 2A is a back cover of the table 2.

Next, the connection structure of the printed boards 14 and 7 by the above-mentioned flexible cord 15 will be described in detail.

FIG. 4 shows the flexible cord 1 before attachment.
It is a figure which shows 5. As shown in the figure, the flexible cord 15 has the printed circuit boards 14,
It has connection portions 15A and 15B with the connection terminal 7. Each connection part 15A,
Each of the flexible cords 15B is formed so as to project from opposite sides of the flexible cord 15 in the longitudinal direction. At the end of each connecting portion 15A, 15B, there is a land 15 which is electrically connected to the cord connector of each printed circuit board 14, 7.
Cs are arranged side by side. Further, the flexible cord 15 includes a plurality of (two in this example) slits 151,
Holds 152. Each slit 151, 152 is provided along the longitudinal direction of the flexible cord 15, and is provided at a position that divides the width W of the flexible cord 15 substantially evenly.

The flexible cord 15 has the positions of the slits 151 and 152, that is, the alternate long and short dash line A shown in FIG.
1 and A2 are used as folding lines and are folded in three layers. The state of the flexible cord 15 folded in three layers is shown in FIG.

FIG. 6 shows a state in which the flexible cord 15 folded in this manner is incorporated in a disc reproducing apparatus. This figure is a view of the disk reproducing device when the back cover is removed and viewed from the back side. As shown in this figure, the flexible cord 15 is housed in the cabinet 1 in a posture in which the flexible cord 15 stands substantially perpendicular to the surface of the optical disc mounted on the table 2. Both ends of the flexible cord 15 are fixed to the printed board 14 on the cabinet 1 side and the printed board (not shown) on the table 2 side by using fasteners 81.

The total length of the flexible cord 15 excluding the portions fixed to the cabinet 1 and the table 2 is set to be longer than the maximum stroke length of the table 2. As a result, this disc reproducing apparatus realizes that the predetermined planar shape (for example, S-shape) including the curved portion is substantially maintained throughout the entire process of loading and unloading the table 2 with respect to the cabinet 1. There is.

When a normal flexible cord that is not folded is accommodated in the cabinet 1 in an upright position, the width of the flexible cord is largely reflected in the thickness of the cabinet 1. However, as described above, by folding the flexible cords 15 along the longitudinal direction in multiple layers, the thickness of the cabinet 1 can be kept constant even when the flexible cords 15 having a large number of signal lines are used, or The thickness of the cabinet 1 can be reduced.

FIG. 7 is a view showing the state of the flexible cord 15 when the table 2 is stored in the cabinet 1. From this figure, it can be seen that this disk reproducing device allows the flexible cord 15 to escape laterally in the cabinet 1 when the table 2 is stored. Therefore, it is not necessary to secure a space for accommodating the flexible cord 15 in the thickness direction of the cabinet 1, and the device can be made thin and small.

Further, since the flexible cord 15 is processed into a structure in which the flexible cord 15 is multiply folded in the longitudinal direction, the durability of the flexible cord 15 against twisting and breaking can be improved.

Next, in this disc reproducing apparatus, the table 2 is locked at a predetermined position in the cabinet 1.
Also, the configuration of a mechanism (table lock mechanism) for releasing this lock will be described.

FIG. 8 is a view of the inside of the disk reproducing device as seen from the back side, and FIG. 9 is a view showing the structure of the table lock mechanism.

In these figures, 21 is a slider supported by the cabinet 1. This slider 21

28 is a spring. This spring 28 includes a support portion 29 of the cabinet 1 and a slider 21.
Is connected to the support portion 30 of. The spring 28 always applies a pulling force to the slider 21 in one direction (the direction of arrow B) of the directions orthogonal to the inserting / removing direction of the table 2.

Reference numeral 31 is a rotating member. This rotating member 31
Are supported by a shaft 32 fixed to the cabinet 1 and can rotate about this shaft. The rotating member 31 has a pin 33 protruding in the thrust direction. The pin 33 is inserted into a guide groove 34 provided at one end of the slider 21. Thereby, a mechanism in which the slider 21 and the rotating member 31 are interlocked with each other is configured.

Further, the table 2 has a plurality of (two in this example) protrusions 35 and 36 on the inner side thereof. The cam receiving pins 35a and 36a are respectively attached to the protrusions 35 and 36.
Is set up. On the other hand, the slider 21 has a plurality of cam grooves 37 and 38 for inserting, guiding and holding these pins 35a and 36a.

The cam grooves 37 and 38 have three functionally classified cams a, b and c. Hereinafter, these three cams are referred to as a first cam a, a second cam b, and a third cam c.

When the table 2 is inserted into the cabinet 1, the first cam a comes into contact with the surfaces around the pins 35a and 36a and moves the slider 21 in the direction of arrow B'by the pressure received from the pins 35a and 36a. And at the same time
It has a function of guiding the pins 35a and 36a to predetermined positions in the cam grooves 37 and 38. By the action of the first cam a, the slider 21 is moved in the direction of the arrow B ′ even though the slider 21 receives the pulling force of the spring 28.

The second cam b is in contact with the pins 35a, 36a guided to a predetermined position in the cam groove along the first cam a, and the direction of the pulling force of the spring 28 (direction B).
Slide the slider 21 onto the pins 35a, 36a
Has a function of guiding the pin to the pin lock position d located at the end of the cam groove.

The third cam c moves from the pin lock position d to the pin 35 when the table 2 is discharged from the cabinet 1.
a, 36a and take out these pins 35a, 36a
Has a function of guiding to the position where it can be ejected in the discharging direction of the table 2 by the first cam a.

In addition, the first cam a has pins 35a and 36 which are taken out from the pin lock position d by the third cam c.
It also has a function of ejecting a in the discharging direction (direction A) of the table 2 by using the pulling force of the spring 28.

On the other hand, near the slider 21, a lock releasing mechanism 40 for releasing the lock of the table 2 and the pins 35a and 36a is arranged. The lock release mechanism 40 includes a motor 41, a worm 42, and a plurality of gears 43, 44, 45. The gear 45 of the gear group applies the power of the motor 41 to the slider 21.
It has a protrusion 47 for transmitting to. This protrusion 47
Contacts the cam 46 provided at one end of the slider 21 and transmits the rotational force of the gear 45 to the slider 21.

Reference numeral 50 is a release lever for manually releasing the lock of the table 2 and the pins 35a, 36a. The release lever 50 is supported by the table 2 so as to be movable in the directions of arrows A and A '. A spring 51 is connected between the release lever 50 and the table 2 (52). The release lever 50 is constantly pulled by the force of the spring 51 in the direction of the arrow A ′. The release lever 50 has a tip 50a that can contact the rotating member 31 described above to give rotation to the rotating member 31 or receive a reaction force from the rotating member 31.

Next, the operation of this table lock mechanism will be described.

First, the operation of inserting the table 2 into the cabinet 1 will be described. The user puts a finger on the front panel 8 of the table 2 and pushes the table 2 into the cabinet 1. FIG. 9 shows a state in which the table 2 is being inserted into the cabinet 1. When the table 2 is pushed further in from this state, as shown in FIG.
The pins 35a and 36a of the table 2 are attached to the slider 21.
Of the cam grooves 37, 38 provided on the first cam a. At this time, the slider 21 slides in the direction of arrow B ′ against the tensile force of the spring 28.
The movement of the slider 21 causes the rotating member 31 to slightly rotate in the arrow C direction.

On the other hand, the tip 50a of the release lever 50 is, at a certain point in time when the table 2 is inserted into the cabinet 1,
It collides with the rotating member 31. From this point onward, the forward movement of the release lever 50 is restricted. Even though the forward movement of the release lever 50 is restricted, the table 2 is pushed further inward, so that the spring 51 is gradually extended. Along with this, the pulling force acting on the release lever 50 in the arrow A'direction increases.

When the table 2 is further inserted, the first
As shown in FIG. 1, in the cam grooves 37 and 38,
The positions of the pins 35a and 36a of the table 2 reach the position of the second cam b beyond the position of the first cam a. As a result, the moving direction of the slider 21 is switched to the direction of the pulling force (arrow B) by the spring 28. From this moment, the table 2 is automatically pulled into the cabinet 1 by the pulling force of the spring 28.

Thus, the pins 35a and 36a guided along the surface of the second cam b are, as shown in FIG.
Finally, the pin lock position d located at the end of each cam groove 37, 38 is reached. And each pin 35a, 36a
It is stably held at this pin lock position d. As described above, the table 2 is locked at a predetermined position in the cabinet 1.

The unlocking is achieved by pressing the eject button 9 provided on the front panel 8. When the eject button 9 is pressed, the motor 41 of the lock release mechanism 40 is driven. The power of the motor 41 is transmitted to the slider 21 through the worm 42 and the gears 43, 44, 45. As a result, the slider 21 moves the spring 2
Although it receives the pulling force of 8, it slides a certain distance in the direction of arrow B '.

By the movement of the slider 22, the pins 35a and 36a of the table 2 are moved to the positions shown in FIG.
The cam groove 37, 38 is guided by the surface of the third cam c and is taken out from the pin lock position. After that, the motor 41 is rotated in the opposite direction, and the gear 45 returns to the original rotation position at high speed. At this moment, the slider 21 vigorously slides in the B direction by the pulling force of the spring 28. By sliding the slider 21, the pins 35a, 3
The surface of the first cam a hits the 6a (state of FIG. 10), and the pins 35a and 36a are guided by the surface of the first cam a and pushed out in the table discharging direction. At this time, each pin 3
5a and 36a are pushed out by the pulling force of the spring 28 so as to be repelled by the surface of the first cam a. On the other hand, the tip 50a of the release lever 50 is in contact with the rotating member 31 at least while the pins 35a and 36a are in the cam grooves 37 and 38, respectively. this period,
The force of the spring 51 connected between the release lever 50 and the table 2 acts as a force to pull the table 2 in the discharging direction.

Therefore, when the lock of each pin 35a, 36a is released and the table 2 is discharged, the spring 51
The pulling force can also be used as a force to eject the table 2 at the same time. With this configuration, the slider 2
It is possible to flip the table 2 farther than the case of flipping the table 2 only by the force of the spring 28 connected to 1.

Next, the operation when the release lever 50 is used alone to release the lock will be described. The release of the lock using the release lever 50 is performed manually, for example, at the time of a power failure or a failure of the table lock mechanism.

The user first inserts a wire or the like into the small hole 10 provided in the front panel 8 and pushes the release lever 50 inward while applying the wire to the tip 50b of the release lever 50. As a result, as shown in FIG. 12, the rotating member 3
1 is slightly rotated in the direction of arrow C. When the rotating member 31 slightly rotates in the direction of arrow C, the slider 21 moves in the direction of arrow B ′ against the pulling force from the spring 28. The subsequent operations are the same as those described above.

As described above, since the table lock mechanism of this disc reproducing apparatus has a relatively small number of parts and a simple structure, the entire apparatus can be made compact and lightweight. Further, since the moving direction of the slider 21 in the table lock mechanism is limited to the left and right directions, the depth of the entire device can be reduced. In addition, the table lock mechanism can largely repel the table 2 from the inside of the cabinet 1 at the time of unlocking, although it does not have a dedicated spring for ejecting the table 2 or a dedicated component similar thereto.

Next, a mechanism for correcting the posture of the disk mounted on the table 2 when the table 2 is inserted into the cabinet 1 will be described.

As shown in FIGS. 1 to 3, 14 and 15, the surface of the upper cabinet part 1A facing the turntable 5 is for correcting the posture of the disk mounted on the table 2. Is formed with a protrusion 61. Further, if the turntable 5 is provided with the protrusion 61,
When the disc floats from above, it also has a function of contacting the upper surface (label surface) of the disc to hold the flotation of the disc to a constant height.

Further, more preferable conditions for the position where the protrusion 61 is provided are as described below. FIG.
FIG. 6 is a diagram showing the relationship between the disc surface and the position of a protrusion 61. In the figure, D is a disc, D1 is a data recording area on the disc, and D2 is a clamping area located on the inner circumference side of the data recording area D1. Further, the arrow X indicates the direction in which the disc D and the table 2 are taken in and out. As shown in this figure, the projecting portion 61 is the innermost circumference facing the width WA of the clamping area D2 or the center of the center hole of the disc D in the direction perpendicular to the loading / unloading direction X of the disc D. It is preferably provided inside the width WA of the line connecting the tracks. The reason for this will be described later.

Further, as shown in FIG. 15, the height of the tip (lower end) of the protrusion 61 is set higher than the tip (upper end) of the chuck 62 within a range not exceeding the thickness of the disc. There is.

FIG. 17 is a view showing the action of the protruding portion 61 when the table 2 is inserted into the cabinet 1. Here, since the disk D has been mounted on one of the plurality of ball bearings 63 provided on the chuck 62, the disk D is mounted on the table 2 in a tilted state. Each ball pairing 63 is held by the chuck 62 so as to be movable in the radial direction from the center of the chuck 62. Then, each ball pairing 63 is elastically pressed in the direction of pushing it to the outer peripheral side of the chuck 62 by a spring (not shown).

When the table 2 having difficulty in mounting the disc D is inserted into the cabinet 1 as described above, the upper surface (label surface) of the lifted portion of the disc D contacts the tip surface of the protrusion 61. When the table 2 is continuously inserted into the cabinet 1, the lifted portion of the disc D is pressed by the pressure applied from the protruding portion 61 from above.
The ball pairing 63 is pushed into the chuck 62 and lowered. As a result, the disc D is reset on the table 2 in the correct posture.

In this way, the protrusion 61 directly contacts the upper surface (label surface) of the disc D while
Correct the posture of. In this case, what should be noted is the occurrence of scratches on the surface of the disc D caused by the direct contact between the protrusion 61 and the disc D. The surface of the disc that directly contacts the protrusion 61 is the label surface opposite to the data recording surface. However, if the scratch on the label surface reaches the reflective layer beyond the protective layer, it may not be possible to correctly read the signal from the disc D. Since the protrusion 61 has a fate of coming into contact with the surface of the disc during the process of inserting the disc, some damage is inevitable. However, this disk reproducing device can minimize the damage. That is, as shown in FIG. 16, since the protrusion 61 is provided inside the width WA of the clamping area D2 in the direction perpendicular to the loading / unloading direction X of the disc D, if the disc D is damaged. Even if it occurs, the scratch will occur almost vertically across the track. In other words, the scratch does not occur so as to destroy the continuous recording data (tracks).
Since advanced error correction technology has already been established in the field of optical disks, data can be correctly reproduced by this error correction function unless the recorded data is continuously destroyed in a long section.

Further, the height of the tip (lower end) of the protrusion 61 is within a range not exceeding the thickness of the disk D, and the chuck 6 is
Since it is set to a position higher than the tip (upper end) of 2, there is no concern that the disc D will come off the turntable 5 during reproduction.
