On the mechanical chassis 4, a disk motor (not shown) for driving the turntable 5, an optical pickup 6, and a pickup feed mechanism (a feed motor 7, a guide shaft 8, etc.) are mounted.

The mechanical unit 2 holds a clamper 10 via a clamper holder 9 (see FIG. 2). Further, a drive mechanism (not shown) for tray loading and disc clamping is provided in the mechanical unit 2.
Is provided.

The details of each section will be described below.

The tray will be described with reference to FIGS.

The tray 1 is composed of a tray frame 11 and a movable tray movable portion 12 supported by the tray frame 11 so as to be able to move up and down (in the thickness direction of the disk). A recess 12a on which a disk is mounted,
An opening 12b for inserting a turntable and reading a disk by an optical pickup, and four disk holders 13 for restraining the disk between the bottom of the concave portion are provided.

As shown in FIG. 3, each disk holder 13 is rotatable between a position shown by a solid line and a position shown by a dotted line. When each of the disk holders 13 is at the dotted line position, the disk D is in the state of being restrained in the tray mounting concave portion 12a, and when at the solid line position, the disk is in the released state. FIG. 3 shows that the tray 1 is the mechanical unit 2
In this state, the disk D is restrained in the tray mounting recess 12a.

Each of the disk holders 13 rotates simultaneously with the movement of the movable tray 12 with respect to the tray frame 11.
As shown in FIG. 1 and FIG.
The upper and lower surfaces of the main surface rise and fall between a height at which the upper end of the main surface is flush with the upper surface of the tray frame 11 and the height at which the upper end of the main surface falls a predetermined distance H from the upper surface of the tray frame 11. When the movable portion 12 is at a height flush with the upper end surface of the tray frame 11, each disk holder 13 is located at the disk restraining position, and at a height lowered by a fixed distance H from the upper end surface of the tray frame 11. At one point, it is localized at the disc restraining release position.

A mechanism for interlocking the lifting and lowering of the tray raising and lowering movable section 12 with the rotation of the disk holder 13 will be described with reference to FIGS.

FIG. 4 is a sectional view when the disk holder 13 is located at the disk restraining position, and FIG. 5 is a plan view thereof. FIG. 6 is a cross-sectional view when the disk holder 13 is located at the disk release position, and FIG. 7 is a plan view thereof.

As shown in these figures, the disk holder 13 is rotatably supported by an elevating guide pin 21 protruding from the tray elevating movable part 12. The tip of the elevating guide pin 21 is inserted into a pin insertion hole 11a provided in the tray frame 11, and is positioned at the tip of the elevating guide pin 21 so that the elevating guide pin 21 is not detached from the pin insertion hole 11a. Is provided with a large diameter portion 21a.

The lifting guide pin 21 has a coil spring 2
The coil spring 22 generates an urging force in the direction of lifting the tray lifting / lowering movable portion 12 from the tray frame 11. One end of the coil spring 22 is fixed to a spring stopper 13 a of the disk holder 13, and the other end is fixed to a spring stopper 11 b of the tray frame 11. Accordingly, the coil spring 22 also generates a force for urging the disk holder 13 in the rotation direction of the arrow R with the lifting guide pin 21 as a fulcrum.

Further, a release pin 23 is provided on the disk holder 13 so as to protrude in the disk surface direction. The release pin 23 is in contact with a pin guide 24 provided on the tray frame 11. The pin guide 24 is used for the tray frame 11
The release pin 23 is guided in accordance with the elevation of the tray elevating movable part 12 with respect to the
Rotate around 1 as a fulcrum.

Next, the operation when the disk D is mounted on the tray 1 will be described.

The tray raising / lowering movable portion 12 and each disk holder 13 are in a position state (a state where the disk can be restrained) shown in FIGS. 4 and 5 by the urging force of the coil spring 22.

When the disk D is mounted on the tray 1, the movable member 12 is lowered by the finger or the like to the full inside of the tray frame 11 against the urging force of the coil spring 22. As shown in FIGS. 1 and 2, the tray elevating and lowering portion 12 is provided with a mark 25 indicating the most suitable position as a finger contact position when lowering the tray with a finger. The user can easily understand how to mount the disc.

When the movable member 12 is lowered, the release pin 23 projecting from the disk holder 13 is guided by the pin guide 24 provided on the tray frame 11, and as a result, the disk holder 13 is rotated by the rotation of the coil spring 22. It turns in the direction against the power. When the tray elevating movable part 12 is lowered to the full, as shown in FIGS. 6 and 7,
The disk holder 13 rotates to a position where the disk restraint is released. Then, the disk D is dropped into the concave portion 12a of the tray 1, and the operation of mounting the disk on the tray is completed.

When the finger is released from the movable part 12, the movable part 12 is returned to the original height position by the urging force of the coil spring 22, and at the same time, the disk holder 1 is moved.
3 rotates to the disk restraining position.

In FIG. 7, reference numeral 26 denotes a hold rib for fixing the disc holder 13 at the disc constraint release position. The disc holder 13 is further turned from the turning position shown in FIG. 7 in a direction against the rotational urging force of the coil spring 22, and the disc holder 1 is
The disc holder 13 is fixed at the disc restraining release position by fitting the hold projection 13b provided on the disc holder 3. When the present DVD-ROM drive is used in a horizontal reclined position, the disk holder 13 is not actually required. In this case, it is desirable to fix the disk holder 13 at the disk restraining release position.

As shown in FIGS. 8 and 9, a taper 13c may be provided on the upper surface of the distal end of the disk holder 13. With this configuration, when the disk D is mounted, the outer peripheral portion of the disk hits the tapered surface 13a, and when the disk D is pushed in as it is, the disk holder 13 rotates in the direction of the arrow and the disk mounting recess 12a is opened. Therefore, the disk D can be mounted on the tray without performing the operation of pushing down the tray lifting / lowering movable section 12 with a finger.

For example, when the present DVD-ROM drive is used in the vertical upright posture, the lower part of the outer periphery of the disk is first fitted inside the lower two disk holders 13, and then the inner part is placed inside the upper two disk holders 13. The lower part of the outer periphery of the disk may be fitted in the above-described manner (by pushing the disk). A taper 13d is provided on the back surface of the distal end portion of the disk holder 13 to allow the disk to be fitted in an oblique posture, so that the fitting at the lower part of the outer periphery of the disk is not enough to push the disk. Thus, the disc can be mounted on the tray with one hand.

The taper 13d on the back surface of the tip of the disk holder 13 hits the outer periphery of the disk when the disk is taken out of the tray, and rotates the disk holder 13 in the same manner as the taper 13c on the top surface of the tip of the disk holder 13. Therefore, the disk can be taken out of the tray with one hand.

Next, the disk clamp mechanism will be described with reference to FIGS. 1, 2, 10 and 11.

As shown in FIG. 2 and FIG.
0 is fitted into a hole 9a provided in the clamper holder 9, and the upper cabinet 5 of the DVD-ROM drive is mounted.
Pressed from above by 1.

The clamper 10 is integrally provided with a leaf spring 10a. The leaf spring portion 10a is provided so as to protrude from the clamper main body 10 toward the back surface of the upper cabinet 51, and the tip portion 10b of the leaf spring portion 10a
When the clamper 10 is in contact with the first surface, an urging force for pressing the clamper 10 against the hole 9a of the clamper holder 9 is generated. Also,
A magnet plate (or a metal plate) 10 b for magnetic attachment to the turntable 5 is attached to the clamper 10.

As shown in FIGS. 1 and 2, the clamper holder 9 has three clamp guide pins 9b and 9c at both side portions bent at right angles to a plate having a hole 9a for holding the clamper. , 9d. Two of these guide pins 9b,
9c is fitted into a vertical guide portion 2b provided on the side surface of the housing of the mechanical unit 2, and another guide pin 9d is inserted into a cam groove 31a provided on the clamp slider 31.

The clamp slider is driven forward and backward in the loading direction of the tray 1 by a driving mechanism described later. As shown in FIG. 1, the guide pin 9d of the clamper holder 9 holds the clamp slider 3 when the tray 1 is being ejected.
2, the tray 1 is located at the lowermost position of the cam groove 31a when the tray 1 is located at the position where the disk clamp is completed in the mechanical unit 2, as shown in FIG. That is, the clamper holder 9 is configured to move up and down by the forward and backward movement of the clamp slider 31.

The vertical guide portion 2b provided on the side surface of the housing of the mechanical unit 2 guides the guide pins 9b and 9c of the clamper holder 9 only in the vertical direction when the clamper holder 9 moves up and down. Moves up and down in the thickness direction of the disk while fixing the position on the plane along the disk surface.

The disk clamping operation will be described with reference to FIGS.

FIG. 10A shows a state during tray loading, which corresponds to a state from (a) to (b) in the plan view of FIG. At this time, the clamper 10 is at the uppermost position, and is almost in close contact with the ceiling surface of the cabinet 51. After this, loading of tray 1 is executed,
When the tray 1 is inserted to a predetermined position in the mechanical unit 2 (after the tray loading in FIG. 11B is completed), the clamp slider 31 starts moving, and the clamper holder 9 starts lowering.

FIG. 10B shows a state where the clamper holder 9 is being lowered. When the clamper holder 9 descends, that is, moves away from the ceiling surface of the cabinet 51, the clamper 10 is brought into close contact with the clamper holder 9 due to the urging force of the leaf spring portion 10a, and accompanying the descending of the clamper holder 9.

When the clamper holder 9 is lowered, the tray operation projection 32 projecting from the lower surface of the clamper holder 9 presses the vertically movable section 12 of the tray 1 from above to lower the tray frame 11 with respect to the tray frame 11. As a result, as shown in FIG. 11C, the restrained state of the disk by each disk holder 13 of the tray 1 is released.

The disk D mounted on the tray 1 is lifted by the turntable 5 from the bottom surface of the tray mounting concave portion 12a by the lowering of the tray lifting movable section 12. By further lowering the tray elevating movable part 12, the distance between the disk chuck part 5a of the turntable 5 and the clamper 10 is reduced, and the disk chuck part 5a is completely fitted into the center hole of the disk D by the magnetic attraction force between them. Thus, the disk clamp by the turntable 5 and the clamper 10 is completed.

FIG. 10C shows the completed state of the disk clamp. In the disk clamp completed state, the clamper 10 is at a position floating above the clamper holder 9, and the leaf spring portion 10 a of the clamper 10 is separated from the inner surface of the cabinet 51. A centering member 5b is elastically supported by the disk chuck portion 5a via a spring for centering the disk.
The centering member 5b has a tapered surface in the periphery, and is pressed downward by contacting the center hole of the disk D with the tapered surface during disk clamping.

Next, the tray loading and disk clamp driving mechanism will be described with reference to FIGS.

FIGS. 12 and 13 show the whole components of the tray loading / disk clamp driving mechanism, and FIGS. 14 and 15 show only the mechanical part relating to the disk clamp therein.

FIGS. 12 and 14 show the state when the tray is discharged before the tray loading (the state shown in FIGS. 1 and 11 (a)). FIG. 13 shows the state when the loading of the tray 1 is completed (FIG. b)), and FIG. 15 shows a state at the time of completion of disk clamping (a state shown in FIGS. 2 and 11C).

In FIG. 12, reference numeral 35 denotes a motor. The power of the motor 35 is transmitted to a gear 37 via a worm gear 36, and further transmitted to a slider 39 through a gear 37a coaxial with the gear 37 and a rack gear 38.
Thereby, the slider 39 slides in the directions of arrows Y1 and Y2 in the drawing (however, it moves in the direction of Y2 from the state of FIG. 12).

The slider 39 has two cam grooves 40 and 41.
Is provided. The guide pin 42a of the arm 42 is inserted into one cam groove 40 shown by a solid line, and the guide pin 31c of the clamp slider 31 is inserted into the other cam groove 41 shown by a dotted line. Therefore, the movement of the slider 39 causes each of the guide pins 42a and 31c to
Arm 42 and clamp slider 3 guided by
1 each operate.

The arm 42 rotates in the directions of arrows R1 and R2 around the fixed shaft 43 as a fulcrum by the guide of the guide pin 42a by the movement of the slider 39 (however, the arm 42 moves in the direction R2 from the state of FIG. 12). A rack gear 42b is provided at the tip of the arm 42, and a gear 44 is meshed with the rack gear 42b. The gear 44 is meshed with a load rack gear 45 provided on the tray 1. Therefore, the tray 1 is loaded into the mechanical unit 2 by the rotation of the arm 42 in the direction of the arrow R2.

The rotation range of the arm 42 is limited by the cam groove 40 provided on the slider 39. That is, the arm 42 rotates between the time when the guide pin 42a is at the position shown in FIG. 12 of the cam groove 40 and the time when it is at the position shown in FIG. However, the cam groove 40 for guiding the guide pin 42a of the arm 42 is provided with the guide pin 37a further than the pin position of the arm rotation end shown in FIG.
In the moving direction (Y2 direction).

On the other hand, as shown in FIGS. 14 and 15, the clamp slider 31 is supported by the mechanical unit 2 by a guide member (not shown) so as to be movable within a predetermined distance range in the loading direction of the tray 1.

Guide pin 31c of clamp slider 31
Is a guide of the cam groove 41 by the movement of the slider 39.
2 and from the position shown in FIG. 14 to the position shown in FIG. Until the guide pin 42a of the arm 42 reaches the arm rotation end position shown in FIG.
Is not guided in the tray loading direction, and the clamp slider 31 does not move.

The slider 39 is connected to the guide pin 4 of the arm 42.
2a continues to slide in the same direction even after reaching the arm rotation end position shown in FIG. By the movement of the slider 39 after the end of the arm rotation, as shown in FIG. 15, the guide pin 31c of the clamp slider 31 is guided in the unloading direction of the tray, whereby the clamp slider 31 moves in the same direction.

The movement of the clamp slider 31 in the tray unloading direction causes the clamper holder 9 described above to move.
The disc is clamped by guiding the guide pin 9d of the clamper holder 9 to the lowest position of the cam groove 31a provided on the clamp slider 31, as shown in FIG.

In FIG. 15, reference numeral 47 denotes a switch for detecting the position of the slider 39. The push rod 47a is pressed by the slider 39 when the position of the slider 39 reaches the tray discharge completion position during unloading of the tray and when the position of the slider 39 reaches the disk clamp completion position when loading the disk. Each state is electrically detected by falling down in the opposite direction.
