Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a disk drive device for recording and reproducing information by rotationally driving an information recording medium formed in the shape of a disk, such as a magnetic disk or an optical disk. More specifically, the present invention relates to a disk drive device equipped with an autoloading and autoeject mechanism for the information recording medium.

[Background of the idea]

Among disk drive devices that record and reproduce information on a disk-shaped information recording medium (hereinafter referred to as a disk), a disk cartridge (hereinafter referred to as a disk drive device) stores the disk in a hard case made of synthetic resin, for example. This cartridge is inserted into a cartridge holding means such as a cartridge holder (hereinafter abbreviated as a holder) of a disk drive device, and the disk is placed on a predetermined rotating means through the holder. In the case of devices that are installed to perform recording and playback, the disk is housed in a hard case, and various attempts have been made to autoload the disk because it can be handled indirectly through the case. ing.

As an example of this, for example, the present applicant first applied for
There is a disk drive device proposed as 60-30849. As shown in FIG. 16, this disk drive device includes a lever 5 that is swingable about a predetermined shaft 50.
1, a slider 53 that can freely reciprocate along a guide shaft 52, and a coil spring 54 provided between the lever 51 and the slider 53.

To explain this mechanism in more detail, the coil spring 54 is rotatably attached at both ends to the swinging end of the lever 51 and to a part of the slider 53.
The swinging motion of No. 1 and the sliding motion of the slider 53 are associated with each other. As shown in FIG. 17, the slider 53 is provided with an arm 59 having an engaging pin 58 protruding from the engaging groove 57 of the cartridge 56 that can be engaged from the side where the cartridge 56 is attached to the rotating means. As shown in FIG. 18, the engaging pin 58 is configured to be able to engage with the engaging groove 57 from the bottom side in the figure depending on the insertion depth of the cartridge 56, and the engaging pin 58 is After engaging the groove 57, it becomes possible to move in a predetermined direction, and a loading operation is performed.

The loading operation in the disk drive device is performed using the relationship between the elastic force and displacement of the coil spring 54. FIG. 19 is an explanatory diagram of the operation during autoloading, and in particular, this diagram shows the displacement state of the coil spring 54. The coil spring 54 drawn with a solid line shows the standby position. Since the lever 51 is prevented from rotating by engaging with the eject lever 60, when the slider 53 is pushed backward (in the direction of arrow X) as described above, the coil spring 54 engages the spring hooking hole 61 of the lever 51. Rotate counterclockwise around the center. When the coil spring 54 rotates counterclockwise, the interval between the free ends of the coil spring 54 gradually narrows, and when the free ends come on a straight line P perpendicular to the arrow A, the interval between the free ends becomes the narrowest, and the coil spring 5
The repulsive force at No. 4 is maximum (the position where the coil spring 54 is indicated by a dotted line). Until the coil spring 54 is in the dotted line position, the cartridge 56 is pushed into the disk drive by an external force, such as by hand or other mechanical means.

As the slider 53 moves in the direction of the arrow X while the coil spring 54 is displacing from the position shown by the solid line to the position shown by the dotted line as shown in the same figure, the tip abutting portion 62 of the slider 53 moves to the holder 67 shown in FIG.
gradually returns upward along the inclined surface 64 of the regulating piece 63 that rises diagonally to the right. As a result, the engagement pin 58
protrudes onto the disk insertion path 65, enters the engagement groove 57 of the cartridge 56, and slides the slider 5.
3 engages with the cartridge 56.

Referring again to FIG. 19, the displacement of the coil spring 54 will be explained.
(the free end inserted into the spring hanging hole 66)
When it crosses the straight line P, its free end is continuously pushed in the direction of the arrow X by the accumulated repulsive force of the coil spring 54 (see the coil spring 54 indicated by the two-dot chain line). The action of the coil spring 54 causes the slider 53 to move in the direction of arrow X along a guide groove (not shown) of the holder 67, whereby the cartridge 56 is automatically drawn into the disk drive device halfway.

In this way, before the coil spring 54 reaches the position shown by the two-dot chain line in FIG.
The lock release protrusion 68 provided at the rear end hits a rising piece of a lock lever (not shown), and
It will be located directly above the rotating means. and,
From this position, it is mounted on the rotating means by a mechanism not shown, and recording and reproduction are performed.

When recording and reproduction are completed, an auto-eject operation is performed. FIG. 20 is an explanatory diagram of the operation of the rotary lever 51 and the coil spring 54 during auto-eject. In the figure, the rotating lever 51 and the coil spring 54 shown in solid lines are in a state before being ejected. As described above, as the eject lever 60 is pulled, the rotary lever 51
rotates counterclockwise about the pin 50 to the position shown by the dotted line, and this forced rotation causes the coil spring 54 to be displaced to the position shown by the dotted line, so that the spacing between the free ends of the coil spring 54 becomes the narrowest. and a repulsive force is accumulated. When the rotation lever 51 has rotated to the position indicated by the dotted line, the holder 67 has reached a position where it can be ejected.

As the ejector motor (not shown) continues to drive, the ejector lever 60 is pulled back to its pre-eject state, and as the ejector lever 60 returns, the rotary lever 51 rotates from the dotted line position to the solid line position. And the coil spring 54
The coil spring 54 is pushed to the position shown by the one-dot chain line in FIG. 20 by the repulsive force accumulated in the coil spring 54 and the rotational force of the rotation lever 51. With this displacement of the coil spring 54, the slider 53 moves in the direction of arrow Y along the guide groove 52 of the holder 67 as shown in FIG.
The cartridge 56 inside is also pulled in the same direction.

When the slider 53 moves, the distal end abutting portion 62 of the arm portion 59 of the slider 53 touches the regulating piece 63 in the holder 67.
When the slider 53 hits the inclined surface 64, the slider 53 moves further forward (in the direction of the arrow Y).
The arm portion 59 is bent downward along the inclined surface 64. As a result, the engaging pin 58 comes out of the engaging portion 57 of the cartridge cartridge 56 and moves downward from the disk insertion path 65, as shown by the solid line in FIG. is discharged from. In this way, the auto-eject operation of the cartridge 56 is completed.

When ejecting the cartridge 56 manually,
Press the eject button on one end of the eject lever 60. Then, the eject lever 60 and a lever pulling member (not shown) move, and accordingly, the lever 51 rotates and performs the same operation as in the case of the auto eject described above, and the cartridge 56 is ejected. .

This manual ejecting function of the cartridge 56 was provided because it was necessary to take out the cartridge 56 from the disk drive device in the event that auto-ejection became impossible due to a power outage or failure, for example. Since the basic operation of the auto-eject utilizes the change in elastic force due to the displacement of the coil spring 54, it is necessary to secure an operating space for the coil spring 54, and there is a limit to miniaturization.

[Purpose of invention]

From this point of view, the applicant has already proposed a disk drive device equipped with a novel electric autoloading and autoeject mechanism that can be downsized. The present invention is proposed as part of this effort, and its purpose is to provide a disk drive device equipped with a manual change mechanism that is simple in structure, reliable in operation, and has an excellent space factor.

[Summary of the idea]

In order to achieve the above objectives, the disk drive device of the present invention, which is capable of autoloading and autoejection, is always elastically biased toward the cartridge insertion side and can reciprocate on the frame to transport the disk cartridge. a lever member capable of regulating the position of the loading member during disk recording and reproduction; a supporting means for supporting a gear group driven by a loading motor; and a lever member that meshes with the final stage of the gear group to A rack that converts the rotation of the ding motor into a linear reciprocating motion and transmits it to the load member, a springing means that springs the lever member and the support means in opposing directions, and engagement between the lever member and the load member. and a manual change mechanism including an operating member capable of displacing the lever member and the support means in directions away from each other in order to disengage the gear group and the rack, respectively. .

The load member 4 on the side of the cartridge holding section 7a
A load member drive mechanism 8 is provided on the frame 1 on the distal side of the frame 1 . Load member drive mechanism 8
consists of a loading motor 8a, a gear group 8b driven by the motor 8a, and a rack 8c in which the final stage gear of the gear group 8b meshes, and a support shaft 33 disposed on the lower surface of the frame 1. It is attached to a support plate 8d (FIG. 12) as a support means that can swing parallel to the plane of the paper in FIG. As shown in FIGS. 1a and 1b, the support plate 8d has a protrusion on the holder 7 side that protrudes from the lower surface of the frame 1 and is provided with an engagement groove 8e that engages with an operating member 15a of a manual change mechanism 15, which will be described later. An engaging portion 8h of a spring 8g is formed at the upper portion on the same side as the piece 8f, and the spring 8g biases the support plate 8d toward the frame 1 side. Furthermore, an engagement groove 8i with which a part of the load member 4 engages is formed on the upper surface of the rack 8c on the load member 4 side. This groove 8i is formed with a predetermined stroke that allows the load member 4 to perform a switching action, which will be described later. Further, a notch 8j is formed on the lower surface side of the approximately central portion of the rack 8c, and a part of the lock lever 15e shown in FIGS. 1 and 13 is freely installed in the notch 8j when the rack 8c is not loaded.

A manual change mechanism 15 disposed on the lower surface side of the frame 1 has a fourteenth
The operating member 15a shown in the figure, the support plate 8d,
The device shown in FIG. 13 is equipped with a switch 15b of the loading motor 8a, a lock pawl 15c of the loading member 4, and a lock release pawl 15d loosely attached to the notch 8j of the rack 8c, and is capable of swinging about the support shaft 33. The support plate 8d and the lock lever 15e are biased toward each other by a spring 8g. The switch 15b, in which the switching rod 15f protrudes from the side surface of the lock lever 15e so as to come into contact with the lower surface of the frame 1, is activated by the end surface of the load member 4 coming into contact with the lock pawl 15c and pushing the lock lever 15e downward. Bar 15f
is set so that the loading motor 8a is extended and the switching operation of the loading motor 8a is performed. Also,
The operating member 15a includes an operating end 15g that can be pressed on the cartridge insertion side A of the frame 1, and an abutting portion 1 that can come into contact with the lock claw 15c when pressed.
5h, and the operating member 15a is always urged toward the cartridge insertion side by a spring 15i.

The holder 7 further includes a shutter opening/closing member 3 that opens the shutter 3b when the cartridge 3 is inserted.
4, and a metal top cover 38 is attached to the top of the frame 1, which protects the internal mechanism and serves as an electrical shield.

<Autoloading Operation> Next, the autoloading operation of the disk drive device configured as described above will be explained step by step.

First, as shown in FIGS. 7 and 9, when the cartridge 3 is inserted from the cartridge insertion opening 7d of the holder 7, if the orientation of the cartridge 3 is correct, a part of the cartridge 3 will be inserted into the joint 30.
It is inserted to the deepest part of the holder 7 without contacting the locking part 30d of the cartridge 3, and the distal end 3 of the cartridge 3
The inclined portion 3f formed at one end of c is the joint inter 3.
0, and the cartridge 3 is set in a predetermined position. Then, when the inclined part 3f of the cartridge 3 comes into contact with the inclined part 30b, the joint inverter 30 rotates clockwise in the drawing around the shaft 30c, and the escape groove 7g of the holder 7
The tip portion 30a of the joint inter 30, which was protruding laterally from the cartridge, engages with the engagement groove 3a of the cartridge 3, and
It becomes possible to load the cartridge 3 toward the turntable 9.

On the other hand, if the cartridge 3 is inserted in a direction other than the predetermined direction, the corner portion of the cartridge 3 other than the inclined portion 3f, for example, the corner portion 3g of the distal end portion 3c of the cartridge 3, will be closer to the cartridge than the inclined portion 30b. It comes into contact with the locking portion 30d formed on the side of the insertion port 7d. Then, approximately the locking portion 30
It becomes impossible to insert beyond the d position, and the jointer 3
Since the tip 30a of the cartridge 3 is also unengageable, the cartridge 3 is simply inserted loosely into the holder 7.
It cannot be loaded.

Next, after inserting the cartridge 3 in a predetermined direction and setting it at a predetermined position, when the cartridge 3 is slightly pushed in the cartridge insertion direction, that is, in the direction of the magnetic head 19, the load member 4 is slightly moved accordingly. Move in the same direction, groove 1c of frame 1
Lock lever 15e protruding from the bottom surface to the top surface side
Press the lock claw 15c against the lower side of the frame 1. When the lock lever 15e is pushed downward, the switch rod 15f of the switch 15b
extends to the bottom side of the switch 15b and closes the contact point of the switch 15b.
The loading motor 8a is turned on via a control circuit (not shown). Loading motor 8a
When turned ON, it starts rotating in the loading direction,
The rack 8c moves in the loading direction via the gear group 8b, and the loading member 4 moves in the same direction. When the cartridge 3 reaches the end of the guide groove 7h in the advancing direction while being pulled by the jointer 30 as the load member 4 moves, the hub 3d of the cartridge 3 is positioned directly above the turntable 9. I will do it. When the rack 8c further moves in the loading direction from this position, the holder 7 is moved as shown in FIG.
Since the load member 4 moves further in the same direction in accordance with the movement of the rack 8c while keeping its position in the direction parallel to the frame 1, the moving protrusion 7f engaged with the cam groove of the cam portion 6 moves. It descends along the inclined cam portion 6a, and the entire holder 7 descends accordingly. Then, the moving protrusion 7f is connected to the parallel cam portion 6b.
When this is reached, the fixing protrusion 7e engages with the guide groove 5c of the side plate of the load member 4, and the cartridge 3 is housed in a predetermined position. At this time, the lock pawl 15c fits into the groove 5d formed in the loading member 4, and at the same time, the lock lever 15e moves up toward the frame 1, the switch 15b opens, and the loading motor 8a stops.

On the other hand, since the load arm 12a is supported by a support member 29 disposed on the upper surface of the holder 7, the load arm 12a is spaced apart from the lower carriage 12 while the holder 7 is in the upper position. A cartridge 3 can be inserted between a load arm 12a and a magnetic head 19 provided on the carriage 12. Therefore, cartridge 3
The load arm 12a is in a position away from the cartridge 3 until it is located directly above the turntable 9. Then, as the holder 7 descends, the load arm 12a also gradually descends, and the disc 11
When placed on the turntable 9, the magnetic head 19 of the load arm 12a is brought into contact with the upper surface of the disk 11. In this state,
The lower surface of the disk 11 contacts the magnetic head 19 on the carriage 12 side, making it possible to record and reproduce data on both sides (FIGS. 8 and 11).

In addition, the shutter 3b of the cartridge 3 is configured such that the tip of the shutter opening/closing member 34 provided in the cartridge holding portion 7a of the holder 7 is rotated as shown in FIG. The shutter 3b is engaged with a shutter opening/closing groove 3e formed in the tip 3c to slide the shutter 3b in the lateral direction, and is completely opened when the cartridge 3 is positioned directly above the turntable 9. Since the shutter opening/closing member 34 is shaped to push the side surface of the shutter 3b in the lateral direction when the shutter is opened or closed, due to the action of a spring (not shown) that constantly biases the shutter 3b in the closing direction within the cartridge 3, At the time of ejection, the shutter 3b is closed as the cartridge 3 retreats.

<Auto-eject operation> Next, the auto-eject operation will be described.

The operation during auto-eject is roughly the opposite of the operation during auto-loading, so it will be briefly explained. First, recording and playback of disk 11 is completed,
When an eject signal is output from a control circuit (not shown), the loading motor 8a starts rotating in the opposite direction to that during loading. Loading motor 8a
When the gear starts rotating in the opposite direction, the rack 8 is rotated through the gear group 8b.
c begins to move to the cartridge insertion side A. When the rack 8c starts to move, the tip of the rack 8c comes into contact with the lock release pawl 15d, and the lock lever 15
Push e down to the bottom of frame 1. When the lock lever 15e is pushed down, the lock lever 15e
eThe lock claw 15c at the tip also lowers, and the load member 4
It comes off from the groove 5d. When the load member 4 is disengaged from the groove 5d of the lock pawl 15c, it becomes movable in the eject direction, and the load member 4 is moved in the eject direction by the action of the loading motor 8a and gear group 8b. When the load member 4 reaches a predetermined position (initial position upon insertion), the lock pawl 15c that was in contact with the lower surface of the load member 4 projects upward from the groove 1c of the frame 1 and locks the tip of the rack 8c. At the same time, the lock lever 15e goes up, opening the switch 15b, stopping the rotation of the loading motor 8a, and completing the ejecting operation. At this time, the cartridge 3 protrudes a predetermined amount from the holder 7 with the shutter 3b closed, and the cartridge 3 is taken out by grasping this protruding end.

<Manual Reject Operation> Even if the disk drive device is equipped with an autoloading/auto-eject mechanism configured as described above, there may be cases where the cartridge 3 cannot be removed from the disk drive device due to a power outage or malfunction during use. arise. In order to prevent this, it is necessary to provide a mechanism for ejecting the cartridge 3 using only a mechanical system without intervening an electrical system. The manual change mechanism 15 provided in this device is for the above-mentioned emergency, and the operation member 15
The cartridge 3 can be ejected simply by pressing the operating end 15g of the cartridge a. The manual reset operation in this embodiment will be explained below.

FIG. 1a is a partially omitted perspective view showing the state of each component of the manual change mechanism 15 when it is not in operation. In this state, the support plate 8d and the lock lever 15e are pulled together by the spring 8g, so the final stage of the gear group 8b is engaged with the rack 8c, the lock lever 15e is in contact with the lower surface of the frame 1, and the lock claw is in contact with the lower surface of the frame 1. 15c and a lock release claw 15d protrude from the upper surface of the frame 1. The operating end 15j of the operating member 15a is engaged with the engagement groove 8e of the protruding piece 8f formed on the lower side of the support plate 8d on which the gear group 8b is installed. The engagement groove 8e is formed in the shape of a cam groove and includes a parallel portion 8k and an inclined portion 8m. Normally, the operating end 15j is connected to the cartridge insertion side A of the parallel portion 8k by the action of the spring 15i.
is in contact with.

At the time of manual adjustment, as shown in FIG. 1b, the operating end 15g of the operating member 15a is
When pushed in the direction, the operating end 15j comes into contact with the inclined portion 8m of the engagement groove 8e of the support plate 8d. When pushed further from this position, the support plate 8d rotates in the direction of arrow C about the support shaft 33 along the inclined portion 8m. When the support plate 8d rotates in the direction C, the gear group 8b is lifted upward, the final stage of the gear group 8b is separated from the rack 8c, and the rack 8c becomes free. Then, the contact portion 15h contacts the lock pawl 15c of the lock lever 15e, and the lock lever 15e rotates in the direction of arrow D about the support shaft 33. By further pushing the operating member 15a, the lock pawl 15c comes into contact. It comes into contact with the lower surface of the portion 15h. When the lock pawl 15c comes into contact with the lower surface side of the contact portion 15h, the lock pawl 15c is unlocked, and the load member 4 returns to the cartridge insertion side A by the elastic force of the spring 5k. During this time, the holder 7 also rises, the load arm 12a is also released, and the cartridge 3
also returns to the state at the time of insertion. After that, when you release your hand from the operating end 15g, the operating member 15a also returns to its pre-operation state due to the elastic force of the spring 15i. Along with this, all mechanisms return to their state before the cartridge 3 was inserted, and the next operation is performed. It will be ready for.

In this return mechanism, the support plate 8d is pushed up,
The lock lever 15e can be pushed down by a slight stroke using the slope of the cam, and the return operation is entirely based on the elastic force of the spring, so the manual reset operation can be performed with an extremely small force.

Furthermore, since the operating stroke amount of the operating member 15a in the direction parallel to the frame 1 surface and the operating stroke amount of the lock lever 15e and the support plate 8d in the direction perpendicular to the frame 1 surface are extremely small, there is no space for these operations. There is no need to secure a wide range of
It has a good space factor and can contribute to miniaturization of disk drive devices.

[Effect of idea]

As described above, in the disk drive device of the present invention, which can be ejected by flipping up and down the support plate and the lock lever with respect to the frame surface using the operation member to release the lock on the load member, all that is required is to release the lock. Since the mechanism has been formed into a mechanism that can be easily ejected, the ejection structure is simple and reliable manual eject operation can be guaranteed, and all operating strokes are minimized, making it extremely space-efficient. This has the effect of providing an excellent disk drive device.
