Abstract

PROBLEM TO BE SOLVED: To solve the problem of the constitution of a conventional disk unit being complicated, because various operational states are set by a slide plate or the like. SOLUTION: When a rotary body 15 arranged on the lower surface of a base board 2 is rotated from a stand-by positioning γ2 direction, carry member 14 is moved in Y1 direction, and an MD held by a drawing member is carried to the depth of equipment. Since a support means is turned simultaneously and the MD held by a holder 11 is descended to the drive position, the MD is loaded on a turntable T and the playback operation of the MD is enabled. When the rotary body 15 is rotated farther in the γ2 direction, the carrying member drives a head support member and a magneto-optical head approaches a disk in the MD, enabling recording operation. Since various operational states can be set by the rotary body 15, the constitution of the disk unit 1 can be simplified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device for recording and / or reproducing data on and from a disk such as an MD (mini disk) or a CD (compact disk). The present invention relates to a disk device capable of performing such operations.

[0002]

2. Description of the Related Art In a loading type disk device such as an MD (mini disk) or a CD (compact disk), when a cartridge containing a disk or a disk itself (hereinafter, referred to as a disk, etc.) is inserted through the entrance, the entrance is opened. There is a type in which the disk or the like is temporarily held by a holding member such as a holder at a nearby insertion and ejection position.

In the disk device, a holder holding a disk or the like horizontally moves in the front-rear direction between the insertion / ejection position and a standby position at the back of the disk device, and further moves the standby position and a driving position below the standby position. For example, there is provided a transport unit that moves up and down in the vertical direction to set various operation states such as a reproduction state and a recording state.

The transfer means is movable in the front-rear direction in parallel with the left and right side plates of the disk device, and has a pair of slide plates having cam grooves formed in a plane in an inclined manner; A long groove extending linearly in the horizontal and vertical directions on the plate.

[0005] The holder is provided with a support portion extending outwardly, and the support portion is supported by being inserted into the long groove and the cam groove, respectively. The holder can be moved back and forth and ascending and descending by moving both slide plates constituting the transfer means in the front-rear direction by driving means such as a driving motor.

[0006] At the back of the disk device, a rotation driving means for rotating the disk and recording and / or recording on the disk are provided.
Alternatively, a pickup device for reproducing a disc is provided.

When a disk or the like is held by the holder,
By moving the slide plate horizontally from the insertion / ejection position to the standby position and then from the standby position to the lower drive position, the disk is held by the rotary drive unit at the drive position, Operation state. Then, predetermined rotation is given by the rotation driving means, and recording and / or reproduction of the disk is performed by the pickup device.

[0008]

However, in the above-mentioned conventional disk drive, the rotational force of the drive motor is converted into a linear force in the front-rear direction of the slide plate. It requires a large driving force to overcome. Therefore, the size of the drive motor is increased, and furthermore, a large amount of electric power is required to drive the drive motor itself.

If the moving amounts of the left and right slide plates are different, the horizontal movement and the vertical movement of the holder are hindered, and it is difficult to smoothly shift to the various operation states. For this reason, a link member or the like is required for moving both slide plates by a uniform moving amount in the left and right directions, and there is a problem that the configuration of the transporting means is complicated and easily enlarged.

The present invention has been made to solve the above-mentioned conventional problems, and enables a holding member (holder) to be moved horizontally and vertically by a simple structure using a single member without using a conventional slide plate. It is an object of the present invention to provide a disk device having the above configuration.

Another object of the present invention is to provide a disk drive which can smoothly and surely shift to various operation states by using the single member.

SUMMARY OF THE INVENTION According to the present invention, there is provided a holding member for holding a disk or a case body containing the disk, and a retracting mechanism for pulling the disk or the case body inserted into the holding member to a predetermined position in the holding member. A member, a transfer member for moving the retraction member, a disk driving means for driving a disk pulled into a predetermined position in the holding member or a disk in a case body, and a disk for supporting the holding member and for holding the disk on the disk. In a disk device having a driving unit that moves between a driving position approaching the driving unit and a standby position that separates from the driving unit, a rotating body that is rotationally driven by the power of a motor is provided. The transfer member is moved in a direction in which the disk or the case body is drawn into the holding member, and the supporting means further moves the waiting member. It is characterized in that is moved toward the drive position from the position.

In the above, a support piece is formed in the support means, and a guide path for guiding the support piece is provided in the rotating body, and the rotary body rotates to connect the support piece with the guide path. It is preferable that the support means be moved from the standby position to the drive position by guiding.

For example, the rotating body has a rotation axis directed in the moving direction of the holding member, and the guide path includes a lifting section that lifts the support piece and sets the holding member to the standby position; A recess is provided for guiding the holding member to the driving position by lowering the support piece, and an inclined surface formed between the lifting portion and the recess. Further, the rotating body is provided with a ring-shaped side wall, and the lifting portion and the concave portion are formed so as to be displaced in the side wall and in a circumferential direction and a rotating axis direction of the rotating body. It is.

According to the present invention, the loading operation of the disk and the loading and unloading operations of the disk to and from the turntable can be performed by a single member called a rotating body. Therefore, complicated mechanisms such as a slide member and a link member are not required, and the size can be reduced. In addition, since a motor for loading and a motor for moving the holder up and down can be constituted by one motor without requiring a dedicated motor, the number of parts can be reduced.

Furthermore, it is possible to smoothly and reliably shift to various operations simply by changing the rotation direction of the rotating body.
Therefore, a large driving force required for moving the slide plate is not required, so that the size of the driving motor can be reduced. Alternatively, the drive motor can be driven with small electric power.

The present invention also provides a holding member for holding a disk or a case body containing a disk, a drawing member for drawing the disk or case body inserted into the holding member to a predetermined position in the holding member, A transfer member for moving a member, a disk driving unit for driving a disk pulled into a predetermined position in the holding member or a disk in a case body, and supporting the holding member to approach the holding member to the disk driving unit In a disk device having a support means for moving between a driving position and a standby position to be separated, and a rotating body for applying a moving force to the transfer member, a head for recording data on the disk, Head supporting member movably supporting in a moving direction and a separating direction, and a disk supporting the head supporting member. Biasing means for biasing the head support member in a direction away from the disk, and a lift member for lifting the head support member away from the disk are provided. Then, the lift member is operated in the lifting release direction by the moving force of the transfer member, and the head is urged in the direction approaching the disk.

In the above, the transfer member and the retracting member are engaged with each other in a concave and convex manner, and when the disk or the case body is retracted into the holding member by the retracting member, the transfer member and the retracting member are connected to each other. Move together, when the holding member moves to the driving position,
It is preferable that the concave / convex engagement between the transfer member and the retraction member is released, and the lift member is operated in the lifting release direction by the subsequent moving force of the transfer member.

In the above configuration, since the head supporting member can be driven by using the transfer member, a dedicated member for driving the head supporting member is not required. Therefore, the configuration of the disk device can be further simplified.

In this disk drive, a detection switch for detecting the rotation angle of the rotating body is opposed to the rotating body.
It is preferable that the rotation angle of the rotating body is detected from the detection state of the detection switch, and the timing of each operation is controlled.

According to the above configuration, the operation state of the disk device can be detected from the rotation angle of the rotating body, and the timing of each operation can be assured.

During the transfer operation, the supporting piece 10F of the supporting means 10 is supported by the lifting part 15c of the rotating body 15, and the supporting piece 10F of the supporting means 10 slides on the lifting part 15c of the rotating body 15. Therefore, the support means 10 is maintained at the height position of the standby position I. Therefore, it is possible to smoothly transfer the MD case in a horizontal posture.

During the transfer operation, an opening / closing door (not shown) provided in the MD case is opened by means (not shown), and the disc is exposed from the opening inside the MD case.

(Mounting and Demounting Operation of Disk, etc.) When the rotating body 15 is rotated in the γ2 direction, the supporting means 10
Reaches the inclined surface 15b of the rotating body 15 and starts to descend along the inclined surface 15b to the position of the concave portion 15a. Accordingly, since the support means 10 is rotated in the illustrated α2 direction, the holder 11 is moved to the drive position II in the illustrated Z2 direction.
Is lowered.

The fact that the transfer member 14 has been moved to the reproduction position shown in FIG.
2 and SW3. Upon obtaining the detection signal, the control unit stops the rotation of the rotating body 15.

At this time, the retracting member 12 in the holder 11
Is lowered to the driving position II while holding the MD case, so that the clamping plate of the disk in the MD case is brought close to the turntable T. Then, the clamping plate is magnetically attached to a magnet in the turntable T, and the disk is clamped on the turntable T.

At this time, as shown in FIGS. 7A and 7B, the engaging convex portion 12f of the retraction member 12 moves down the engaging concave portion 14b of the transfer member 14 vertically in the Z2 direction as shown in FIG. From 14b, it reaches the inside of the notch 1A1 of the long groove 1A. Therefore, the engaging convex portion 12f and the engaging concave portion 14b
Is disengaged, and only the transfer member 14 can move in the front-rear direction (Y1-Y2 direction).

When removing the MD case,
The rotating body 15 is rotated in the γ1 direction,
The zero support piece 10F starts to climb up to the lifting portion 15c along the inclined surface 15b of the rotating body 15. Therefore, the support means 1
0 is rotated in the illustrated α1 direction, the holder 11 is raised from the drive position II in the illustrated Z2 direction to the standby position I, and the clamping plate of the disk in the MD case can be detached from the turntable T. .

(Reproduction Operation of Disk and the Like) When a disk in the MD case is mounted on the turntable T, the control unit drives the spindle motor 3 and the pickup device. That is, the spindle motor 3 is rotationally driven to give a predetermined rotation to the disk. Further, the motor M1 is driven to rotate the feed screw shaft 4 in the normal rotation direction or the reverse rotation direction, thereby moving the moving base 6A in the radial direction of the disk. At this time, the optical head L provided on the movable base 6A reads information recorded on the disk, thereby reproducing the disk.

The transition to the reproduction operation is performed by the holder 1
1 may be performed as a series of operations when an MD case is inserted, or may be performed when a play button (play button) provided outside the disk device is operated.

(Recording Operation of Disc and the Like) Next, when a recording button (not shown) (not shown) is operated at the reproduction position, the disc device 1 is shifted to a recording state.
That is, the rotating body 15 is further driven to rotate in the illustrated γ2 direction.

When the rotating body 15 is further rotated in the γ2 direction at the reproducing position shown in FIG.
Rack 14a is disengaged from the gear 15d of the rotating body 15 and reaches the sliding portion 15G. In this state, the end of the transfer member 14 in the Y1 direction is in contact with one of the urging arms 19a of the urging member 19, and the transfer member 14 is constantly urged in the Y2 direction. Therefore, the rack 14a of the transfer member 14
The contact portion 14a1 at the tip (see FIG. 4) is
Sliding part 15G (part where gear 15d is not formed)
Slides in a state where the outer peripheral side surface is pressed in the illustrated Y1 direction.

When the rotating body 15 is further rotated in the γ2 direction, the projection 15F of the rotating body 15
a1 to push the transfer member 14 in the Y1 direction.
Is further moved to the recording position shown in FIG.

At this time, the pressing portion 14 of the transfer member 14
Since c presses the abutted portion 17d (see FIG. 1) of the lift member 17 in the Y1 direction in the figure, the state in which the lift member 17 is rotated in the δ2 direction in the figure is maintained. Therefore, both the support arm 9B and the magneto-optical head 8 supported by the support arm 9B become β2 due to their own weight.
The magneto-optical head 8 is
Approach the top of the disc through the opening in the case.

The fact that the transfer member 14 has reached the recording position is detected by the detection switches SW1, SW2 and SW3 and is notified to the control unit. The control section gives a predetermined rotation to the disk on the turntable T by stopping the rotation of the drive motor M2 and driving the spindle motor 3 to rotate. Further, the motor M1 is driven to rotate the feed screw shaft 4 in the normal rotation direction or the reverse rotation direction, thereby moving the moving base 6A in the radial direction of the disk. At this time, the head support member 9 is moved in the radial direction integrally with the moving base 6A, and the magneto-optical head 8 records information on the disk.

(Release of Recording State) When a stop button (stop button) (not shown) provided on the disk device 1 is pressed,
The disk device 1 stops the recording operation. That is, while the rotation of the spindle motor 3 is stopped, the drive motor M2 is driven to rotate to rotate the rotating body 15 slightly by γ.
Rotate in one direction. Accordingly, the pressing of the rotating body 15 in the Y1 direction by the protrusion 15F against the pressing portion 14c of the transfer member 14 is released. Accordingly, the transfer member 14 is moved from the recording position shown in FIG. 6D to the reproduction position shown in FIG. 6C by the urging force of the urging member 19.

At this time, since the transfer member 14 separates from the lift member 17, the lift member 17
The pressing portion 17c presses the operating portion 9B1 of the support arm 9B. Therefore, the support arm 9
B is rotated in the illustrated β1 direction, and the support portion 9B3 at the tip of the support arm 9B connects the flexible cable 8A to the illustrated Z1.
Lift in the direction. Therefore, the magneto-optical head 8 can be kept away from the disk.

(Ejection) When an unillustrated ejection button (ejection button) provided on the disk device 1 is operated, the control unit drives the motor M1 to
A is moved to the innermost peripheral position in the X2 direction in the figure. At the same time, the drive motor M2 is further rotated to rotate the rotating body 15 by γ.
Rotate in one direction. In the first stage of this rotation, the pressing portion 14c of the transfer member 14 is
Since the outer peripheral side surface of G is slid, the transfer member 14 is kept stopped at the reproduction position. As shown in FIG. 6C, the rotating body 15 is further rotated in the γ1 direction,
When the portion of the rotating body 15 that is in contact with the pressing portion 14c is switched from the sliding portion 15G to the gear 15d, the transfer member 14
Rack 14a meshes with the gear 15d of the rotating body 15. Therefore, the transfer member 14 starts to move in the Y2 direction in the figure by the rotational driving force of the rotating body 15.

Before the transfer member 14 and the rotating body 15 are engaged with each other, the supporting piece 10F of the supporting means 10
5 has started climbing the inclined surface 15b in the side wall 15B and has reached the lifting portion 15c. That is, the holder 11 is moved to the standby position I in the Z1 direction before the transfer force acts on the transfer member 14. At this time, the retracting member 12
The engagement convex portion 12f moves perpendicularly in the Z1 direction from the inside of the notch portion 1A1 of the long groove 1A to reach the inside of the engagement concave portion 14b of the transfer member 14. Therefore, the engagement convex portion 12f and the engagement concave portion 14b are re-engaged, and the retraction member 12 and the transfer member 14 can be integrally moved in the front-rear direction (Y1-Y2 direction). Then, the rotating body 15 becomes γ
By rotating the transfer member 14 and the retraction member 12 in one direction, the transfer member 14 and the retraction member 12 are moved to the insertion and discharge positions in the illustrated Y2 direction. Therefore, at the entrance 11A of the holder 11, the MD case held by the pull-in member 12 can be taken out of the disk device 1.

In the above embodiment, the recording medium in which the disk is housed in the case, such as an MD (mini disk), has been described. However, the recording medium in the present invention is a CD (compact disk) that is not housed in the case. )
Or a recording medium such as a DVD (Digital Versatile Disk). In this case, the disc may be placed and held on a tray instead of the holder, and the tray may be transferred in the insertion and ejection directions, and may be moved between the standby position I and the drive position II.
