BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mass storage device for use in an information processing device, and more particularly, to a disk storage device and a rotary actuator using a hard disk as a disk type information recording medium capable of reading / writing both surfaces.

2. Description of the Related Art [0002] Conventionally, a high speed mass disk device representative of a removable hard disk device and a disk cartridge accommodating a hard disk as a storage medium used therein are the disk storage medium 101 and the disk cartridge of the configuration shown in Figs. 120 is proposed.

As shown in FIG. 33, this disk storage device 101 is provided as a main mechanical element in the disk cartridge loading part 103a having an insertion hole 103a on the front surface of the front side of the mechanical chassis 102. As shown in FIG. It consists of the disk rotation drive mechanism 104 and the read / write head mechanism 105 arranged on the rear half side of the mechanism chassis 102.

And the disk rotation drive mechanism 104 is made so that the spindle motor 108 provided with the chucking magnet 107 may be settled in the range of predetermined height from the opening 106 formed in the center part of the bottom face of the disk cartridge loading part 103. And a sub-chassis (not shown) disposed below the mechanical chassis 102 so as to be lifted and lowered.

In addition, the read / write head mechanism 105 is positioned near the disc cartridge loading portion 103 on the rear half side of the mechanical chassis 102 in order to reduce the size of the apparatus, and is pivoted by the shaft 109 to operate the actuator ( The reading / recording head (following record / reading head) H is provided through the suspension 112 which consists of a leaf spring at the front-end | tip of the actuator arm 111 rotationally driven by 110. As shown in FIG.

The actuator 110 of the read / write head mechanism 105 is fixed to the mechanical chassis 102 side corresponding to the movable coil 110a attached to the rear end of the actuator arm 111 and the movable coil 110a. It consists of the flat magnet 110b and the yoke (not shown) which forms a magnetic circuit, and since the recording / reading head H is provided in the upper and lower pairs, for this reason, it is provided in the front-end | tip of the actuator arm 111 As the suspension 112, which is a pair of upper and lower suspensions 112a and 112b, the two suspensions 112a and 112b are extended and attached to the actuator arm 111 in the centerline extension direction with a predetermined interval up and down. The recording / reading head H is attached to the inner surface side of the front end portions of the suspensions 112a and 112b by a slider attached in a direction orthogonal to the center line, and faces up and down. In addition, the rod bar 113 protrudes in the tip extension direction and is fixed to the front end outer surface side of both suspension 112a, 112b.

In the read / write head mechanism 105 configured as described above, the distal end portion of the actuator arm 111 including the suspensions 112a and 112b is positioned with the disc cartridge loading portion 103 facing the disc cartridge to be loaded. Since it is inserted into the 120, the tip end of the actuator arm 111 is formed in the upper and lower bifurcations, that is, the fork, so as not to interfere with the hard disk, and suspensions 112a and 112b are attached to the upper and lower members. .

Further, on the rear half side of the mechanical chassis 102, a ramp 114 of a sliding block is located in the vicinity of the disk cartridge loading section 103 and positioned near the actuator arm 111, which is a guide of the recording / reading head H. It is fixed toward the disc cartridge loading portion 103, and since the lamp 114 is also inserted into the loaded disc cartridge 120, a bifurcated shape, that is, a recess is formed so as not to interfere with the hard disk to form a fork shape. have. The upper and lower surfaces of the lamps 114 make sliding contact with the rod bars 113 at the ends of the suspensions 112a and 112b of the actuator arm 111, so that the intervals between the suspensions 112a and 112b, i.e., both recording / reading heads. The interval of (H) is maintained.

In the second half of the mechanical chassis 102, a circuit board 115 including a control circuit of the actuator 110, a read / write amplifier of the recording / reading head H, and the like is disposed to be flexible with the actuator arm 111 side. It is connected by the sexual wiring board 116.

On the other hand, the disc cartridge 120 is rotatably rotated to the disc storage portion 123 between the right angled quadrangle upper and lower half members 121 and 122 and the both half members 121 and 122, as shown in FIGS. 33 and 35. It is composed of a stored double-sided read / write magnetic disk, that is, a hard disk 124. A hub 125 formed of ferromagnetic material is attached to the center of the hard disk 124 to correspond to the center hole 126 formed in the lower half member 122.

Further, the front end side of the disc cartridge 120 is inserted along with the suspensions 112a and 112b in which the tip end of the actuator arm 111 is provided with the recording / reading head H over the upper and lower half members 121 and 122. An opening 127 is formed, and the opening 127 is provided with a shutter 128 for opening and closing it. The shutter 128 is journaled vertically around the axis 129 of the upper half member 121, and when the cartridge is not in use, the opening 127 is closed to prevent intrusion of dust, fingers, and the like. The disk storage device 101 is configured to be automatically opened by the loading operation to the disk storage device 101.

In this way, as shown in FIG. 33, in order to load the disk cartridge 120 into the disk storage device 101, the front inserting portion (for the disk cartridge loading section 103 on the front half side of the mechanical chassis 102) ( In 103a, when the opening portion 127 is inserted in the horizontal direction, the shutter 128 is automatically opened by a shutter opening / closing mechanism (not shown). The opening portion 127 is opened. Then, when the disc cartridge 120 is inserted to a predetermined position, as shown in Fig. 34, the portion extending from both of the suspensions 112a and 112b and the trapezoidal portion of the lamp 114 at the distal end of the actuator arm 111 are opened. A portion of the outer periphery of the hard disk 124 is located in the recess of the lamp 114 while being located in the cartridge from 127. In this state, both suspensions 112a and 112b have the rod bar 113 in contact with the high position of the lamp 114 so that the gap is widened and held, so that the gap between the recording / reading heads H is the hard disk 124. ) Is larger than the thickness.

In this state, the spindle motor 108 of the disk rotation drive mechanism 104 moves upward, protrudes a predetermined height from the opening 106 of the bottom center portion of the cartridge loading portion 103 by the suction magnetic force of the chucking magnet 107. The hub 125 of the hard disk 124 is sucked through the center hole 126 of the lower half member 122, and the spindle motor 108 and the hard disk 124 are integrated, that is, the hard disk 124 is a spindle. It is chucked to the motor 108.

Then, at the portion where the spindle motor 108 rotates, and at a constant angular speed, the actuator arm 111 is rotated by the actuator 110 in the cartridge, i.e., in the direction of the hard disk 124, so that both suspensions 112a and 112b are rotated. ), The load bar 113 slides in the low direction from the high side of the lamp 114, so that the magnetic head H is loosely landing on the surface of the hard disk 124. This landing creates an aerodynamic effect between the rotation of the hard disk 124 and the slider that supports the recording / reading head (H), the so-called film of air between the surface of the hard disk 124 and the slider. In the floating state of nm, the recording / reading head H and the hard disk 124 do not contact each other.

In this state, the recording / reading head H is positioned in a predetermined track by the rotational operation of the actuator arm 111, so that reading / writing of information on the hard disk 124 is performed.

In the disk storage device configured as described above, the actuator arm 111 for moving the recording / reading head H and the lamp 114 for jointly operating the recording / reading head H with respect to the hard disk 124 and Since it is arranged in the state facing the disk cartridge loading section 103, pop-up loading and discharging of the disk cartridge 120 to the disk cartridge loading section 103 is impossible, and the actuator arm 111 and the lamp 114 are not allowed. The opening portion 127 is opened in parallel with the bottom of the loading portion 103 in such a manner that the opening portion 127 is opened so as not to interfere with the loading portion. Therefore, when the insertion portion is inserted into the loading portion 103 of the disc cartridge 120, the loading portion ( It is necessary to keep the bottom of 103 in a flat state without protrusions.

Therefore, the spindle motor 108 which sucks and drives the hard disk 124 in the disk cartridge 120 on the bottom surface of the loading section 103 is used to remove the loading section 103 when the disk cartridge 120 is removed. It is necessary to lower than the bottom surface, and in order to raise and lower the spindle motor 108, the support mechanism of the spindle motor 108 is required for stability and certainty, and the configuration is complicated and the cost has increased.

In addition, the actuator arm 111 is formed in a fork shape so as not to interfere with the hard disk, and is configured as an inline arrangement by extending and attaching a suspension 112 for supporting the recording / reading head H to the front end with a centerline extension, In order to reduce the size of the device, the actuator arm 111 is suspended in the disc cartridge 120 loaded in the disc cartridge loading part 103 because the actuator arm 111 is pivoted in the vicinity of the disc cartridge loading part 103. A portion extending from the side 112 to the vicinity of the pivot is inserted from the side surface, which causes the disc cartridge 120 to have a large opening, whereby the shape of the disc cartridge is remarkably limited, thereby providing a degree of freedom in structural design. It is limited and there is the inconvenience of not being able to produce disc cartridges that match as desired.

In addition, the lamp 114 is also formed in a fork so as not to interfere with the hard disk, and it is necessary to separate it from the hard disk 124 at required intervals during the loading / unloading operation of the recording / reading head H. As a result, the distance between the suspensions 112 must be greatly widened. As a result, the lamps 114 are formed to have a thickness as a whole, so that the thicknesses of the disk cartridges and the disk storage devices become large, which hinders the miniaturization of the device. .

In addition, since the suspension 112 is inline with respect to the actuator arm 111, it is susceptible to the torsional mode, which is one of the resonances of the suspension, and the recording / reading head H is in an unstable corresponding state with respect to the hard disk surface. There is a risk of disruption to the reading / recording.

In addition, the lamp 114 is written when the actuator arm 111 is rotated in a state in which the disc cartridge 120 is not loaded for some reason by the recessed portion being opened on the hard disk 124 side, and this is rotated back. Suspensions 112a and 112b having the read head H attached are inserted into the recesses of the lamp 114 and return rotation is impossible, or the write / read head H is broken.

Further, the actuator arm 111 is inserted into the disc cartridge 120, whereby the solder angle of the wiring of the recording / reading head H is restricted to prevent the interference of the disc cartridge 120, and the wiring and soldering operations are performed. There is an inconvenience that the workability of the back worsens.

In addition, since the disk storage device described above needs to be inserted so as not to interfere with the actuator arm 111, the lamp 114, or the like in the loading of the disk cartridge 120, high precision is required for the guide mechanism. It was causing.

SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and an object of the present invention is to provide a disk storage device which can be reliably operated in a stable manner and that can reduce costs.

(3-2) Shutter opening mechanism (Fig. 2, Fig. 3)

This shutter opening mechanism 40 is for opening the head insertion opening 7 of the disc cartridge 1 mounted on the cartridge holder 16 by triggering the cartridge body side as shown in Fig. 2 and the like, and the cartridge holder. It is arrange | positioned at one side plate 16b of (16). This shutter opening mechanism 40 is provided with the shutter release lever 41 which is a balance arm member, and the coil spring 42 which shows one specific example of the pressing member which presses this shutter release lever 41. As shown in FIG. . The shutter release lever 41 acts as a lever main body 41a having a cross-sectional c-shape, an input member 41b as a mimic end projecting apart from each other in the horizontal direction from both sides of the lever main body 41a, and a working end. The contact part 41d which has the member 41c and protrudes on the movement trace of the disc cartridge 1 is provided in the front-end | tip part of the input member 41b.

In order to attach this shutter release lever 41 to the cartridge holder 16, a pair of front and rear openings 23a and 23b are cut into the side plates 16b of the cartridge holder 16 by cutting up and down a pair. Pin support members 43a and 43b are provided. The lever main body 41a of the shutter release lever 41 is interposed between these pin support members 43a and 43b, and is provided in the pin hole provided in each pin support member 43a and 43b, and the pin main body 41a. The shutter release lever 41 is allowed to swing in the horizontal direction on one side of the cartridge holder 16 by penetrating the shaft pin 44 having a head at one end and caulking the other end of the shaft pin 44 through the pin hole. Supported.

In this state, the input member 41b of the shutter release lever 41 is opposed to the opening 23b after the cartridge holder 16, and the action member 41c is opposite to the opening 23a before. The coil part of the coil spring 42 is loosely fitted to the shaft pin 44 which axially supports this shutter release lever 41 to the cartridge holder 16, and the spring member 42a which continues to one end of this coil part is a side plate. The spring member 42b which abuts on 16b and continues to the other end of a coil part is in contact with the lever main body 41a. By the spring force of this coil spring 42, the input member 41b of the shutter release lever 41 is pressed in the direction which enters into the opening part 23b, and, as a reaction, the action member 41c moves from the opening part 23a. It is pressed in the direction of extraction.

In order to limit the amount of rotation of the shutter release lever 41, the inner surface of the lever main body 41a has an input side stopper portion 41e which prevents the input member 41b from entering the opening 23b by a predetermined amount or more, and an actuating member. An operating side stopper portion 41f which prevents 41c from entering the opening 23a for a predetermined amount or more is set. The input member 41b of the shutter release lever 41 passes through the introduction portion 10c of the guide groove 10 of the disc cartridge 1 into the wide portion 10a, and the actuating member 41c guides the guide groove. It passes into the narrow part 10b past the operating part 10d of (10).

As the function of the input member 41b of the shutter release lever 41, the function of the input force of the operating force is different, and also serves as the positioning function of the disc cartridge 1 in the horizontal direction, Since it is required to have a suitable elasticity, in this example, it is formed so that the width | variety may become wide in the width direction of the guide groove 10, and the contact part 41d is formed as the front-end part is bent in the depth direction of the guide groove 10. have. Therefore, the rigidity of the width direction (groove width direction) of the guide groove 10 of the input member 41b is higher than the rigidity of the depth direction (groove depth direction) of the guide groove 10 orthogonal to this, whereby the input member Deformation hardly occurs in the groove width direction at 41b.

On the other hand, since the function of the action member 41c of the shutter release lever 41 mainly presses the operation claw 4f, in this example, it is bent in the depth direction of the guide groove 10 from the vicinity of the lever main body 41a. As a result, the horizontal rigidity is formed to be large. Therefore, the rigidity of the groove width direction of the actuating member 41c is lower than the rigidity of the groove depth direction, whereby the actuating member 41c is easily held in the cartridge holder 16 with respect to the groove width direction so as to easily cause elastic deformation. The disk cartridge 1 can be tracked by swinging in the vertical direction.

Further, as a side plate 16b on the shutter release mechanism 40 side of the cartridge holder 16, on the rear side of the pin support members 43a and 43b, misinsertion prevention for preventing the wrong insertion of the disc cartridge 1 is performed. The convex part 26 is provided. The misinsertion prevention convex portion 26 is formed by expanding a part of the side plate 16b inwards in a hemispherical shape, and the misinsertion prevention convex portion 26 is a guide groove ( 10), the disc cartridge 1 can be completely inserted only when the guide groove 10 is inserted in the misinsertion prevention convex portion 26, and when the disc groove 1 is not matched, the disc cartridge 1 ) Is prevented, whereby it is possible to determine whether the disk cartridge 1 is inserted.

Thus, the operation hook 4f of the shutter member 4 is located in the narrow width portion 10b of the guide groove 10 of the disc cartridge 1, and this operation hook 4f acts as the shutter release lever 41. By pressing on the member 41c, the shutter member 4 is rotated against the spring force of the shutter spring 5, and the head insertion opening 7 and the center core hole 9 are opened together.

(3-3) Information recording and reproducing mechanism (FIGS. 1, 6, 12-14)

This information recording and reproducing mechanism 50 is arranged in the rear portion of the mechanical chassis 17, as shown in Fig. 1 and the like, and has a chevron rotary actuator 51 as a rotary support member and the rotary actuator 51. And a pair of upper and lower sliders 52a and 52b which are movably mounted to the front end portion.

The rotary actuator 51 includes a rotary arm 55 rotatably supported by a fixing unit such as an attachment screw on the mechanical chassis 17, a drive coil 56 fixed to the rotary arm 55, and a pair. Mounting plates 57a and 57b, and a pair of suspensions 58a and 58b fixed to the mounting plates 57a and 57b. The rotary arm 55 of the rotary actuator 51 is rotatably supported on the mechanical chassis by a bearing 59 fixedly coupled to the midway portion in the horizontal direction, and has two periphery portions 55a formed on one side thereof. The fan-shaped drive coil 56 wound around the copper wire is held together.

As shown in Fig. 9, end portions are provided on both upper and lower sides of the distal end portion of the rotary arm 55, and the proximal ends of the mounting plates 57a and 57b are fitted to the end portions for spot welding, caulking or adhesive. By affixing by fixing means, such as a pair, the pair of mounting plates 57a and 57b are opposingly provided with a predetermined clearance gap in the up-down direction. The pair of mounting plates 57a and 57b are formed in an inverted L shape, and the proximal ends of the suspensions 58a and 58b are fixed to spot inner surfaces, such as spot welding, caulking or adhesives, on the inner surfaces of the front ends of these mounting plates 57a and 57b. The gaps, which are respectively fixed by means and formed between the bent portions of the mounting plates 57a and 57b between the ends of the suspensions 58a and 58b, communicate with each other openly. In this way, the rotary actuator 51 is formed by the rotary arm 55, the mounting plates 57a and 57b, and the suspensions 58a and 58b in an L-shape, that is, a chevron in plan view.

The pair of suspensions 58a and 58b are made of a leaf spring type member having elasticity, and the rigidity of the proximal end is set low by providing an opening 60 at the center of the proximal end side to lower the rigidity. Thus, by lowering the rigidity of the proximal end portions of the suspensions 58a and 58b and giving the flexibility to the tip side, the sliders 52a and 52b attached to the distal end can be tilted so that they can be easily undulated in the vertical direction. It is supposed to be done. 10, both edges of each of the suspensions 58a and 58b are bent to the inner surface side to form ribs 58a ₁ , 58a ₂ and 58b ₁ , 58b ₂ , and the inner ribs ( 58a ₁ and 58b ₁ delete the tip side (cut back). In this way, by cutting back the ribs 58a ₁ and 58b ₁ on the inner surface side of the suspensions 58a and 58b, the ribs 58a ₁ and 58b ₁ eliminate the fear of interfering with the lamp arm 92 and thus the ribs 58a. ₁ , 58b ₁ ) can eliminate the need to worry about the existence.

In the middle portions of the suspensions 58a and 58b, convex portions 61a and 61b protruding in a hemispherical shape are respectively provided inside. Between the convex portions 61a, 61b of the suspensions 58a, 58b, a lamp to be described later is inserted at the time of loading and unloading, so that the front end sides of both suspensions 58a, 58b are spaced in the vertical direction. The upper and lower sliders 52a and 52b do not come into contact with both the upper and lower sides of the hard disk HD. The convex portions 61a and 61b may be expanded in the hemispherical shape by adding the throttling process to the suspensions 58a and 58b, or may protrude in the hemispherical shape by external insertion molding or may be formed by various other means.

As the shape of the pair of sliders 52a and 52b, for example, those having a structure as shown in Figs. 12 to 14 can be used. Fig. 12 shows a transverse pressure contour slider (hereinafter referred to as " TPC slider ") 52A as the intermediate floating slider. The TPC slider 52A has air flow grooves 62 extending in the front-rear direction at the center of the back surface of the slider main body forming a block shape. The disk facing surface 63a facing the upper and lower surfaces of the HD), the flow groove end portions 63b and 63c continuous in the front-rear direction formed on both sides of the disk facing surface 63a, and the rotational direction of the protrusion 63 A tapered surface 63d formed on the front side is provided.

According to this TPC-type slider 52A, a constant flight altitude performance (hereinafter, referred to as how the parallel between the disk opposing surface and the disk surface of the slider rising from the surface of the hard disk HD fluctuates in and out of the disk radial direction (hereinafter, referred to as " a " "CFH performance" can be improved, and the speed dependence is small, and the performance of the plate can be obtained substantially in either of the inner and outer sides of the disk radial direction, and the slider can be stably floated from the disk surface. Can be.

Fig. 13 shows a catamarin type slider 52B. The catamaran slider 52B forms a basic shape of the TPC slider 52A and has a structure in which the left and right flow groove end portions 63b and 63c are removed from the protrusion 63 in the above-described embodiment.

14 shows the negative pressure slider 52C. The negative pressure slider 52C generates a negative pressure on the rear surface of the slider by the negative pressure generating groove 62a, and the negative pressure slider 52C generates a negative pressure on the differential pressure between the negative pressure and the positive pressure generated by the air bearing surface (absolute value of the absolute negative pressure of the plus pressure). This causes the slider to float from the disk surface. The negative pressure slider 52C has a shape in which the front portion of the air flow groove 62 is closed, and a negative pressure generating groove 62a is formed which is opened from the center of the rear surface of the slider main body to the rear. According to this negative pressure slider 52C, the CFH performance can be satisfactorily obtained in flat performance similar to the TPC slider 52A, and the slider can be stably floated from the disk surface.

At the front end portions of the sliders 52A to 52C having such a configuration, the magnetic heads 8 for recording and reproduction are opposed to each other. In any of these embodiments, these sliders 52A to 52C have a predetermined intersection between the centerline X of the air flow groove 62 or the negative pressure generating groove 62a and the centerline Y of the suspensions 58a and 58b. It is set to intersect at an angle θ.

In general, the slider is set in such a manner that the extending direction of the air flow groove is parallel to the extending direction of the suspension, but in this embodiment, the crossing angle θ is set to about 70 °. In this manner, the bent angles of the sliders 52a and 52b can be reduced by attaching the sliders 52a and 52b by attaching the predetermined crossing angles θ to the extending directions of the suspensions 58a and 58b. In addition, the said crossing angle (theta) is not limited to 70 degrees like this example, It can set an appropriate angle as needed.

In addition, as shown in Fig. 11, the middle portion of the rotating arm 55 is provided with recesses 64a and 64b by partially cutting the inner side of the upper and lower sides, and rotated by the recesses 64a and 64b. The arm 55 is designed to be lightweight.

The arm contact portion of the flexible printed wiring board 65 is adhered to the rotating arm 55 with an adhesive, and is fixed to the boss portion 55c of the rotating arm 55 with the attachment screw 66.

This is to enhance the rigidity by reinforcing the strength of the rotating arm 55 with the flexible printed wiring board 65 supported by a reinforcing plate such as aluminum. This flexible printed wiring board 65 has the structure by which the base board 65a which is a support reinforcement board, such as aluminum, was adhere | attached on one side, and this flexible printed wiring board 65 with a reinforcement board was added, and By making the cross-sectional shape into a box shape, in this example, the strength of the rotating arm 55 is increased. Thereby, while reducing the weight of the rotating arm 55, the strength of the rotating arm 55 can be increased.

This flexible printed wiring board 65 is connected to the connector 68 via the flexible cable part 67. The connector 68 is mounted on the wiring board 35 arranged on the side of the spindle motor 12, and the wiring board 35 is fixed on the mechanical chassis 17. An electronic circuit is printed-molded by the conductor in this wiring board 35, and the amplifier 36 and other electronic components are electrically connected to this electronic circuit, and the control apparatus is comprised.

Thus, the rotary actuator 51 is bent approximately 90 degrees at the portions of the mounting plates 57a and 57b as shown in Figs. 6 and 19 and the like and forms an inverted L-shape called a chevron. From this shape, the rotary actuator 51 of this example is called a chevron.

In the actuator support 53 for rotatably supporting such a rotary actuator 51, a flat magnet 37 curved in an arc shape so as to face the driving coil 56 from below is mounted and fixed. The magnet 37 has the NS anode magnetized in the plane direction (for example, the side close to the spindle motor 12 is the S pole and the far side is the N pole), and the drive coil 56 and the magnet are By adjusting the direction and magnitude of the current flowing through the drive coil 56 in the magnetic field set to 37, the rotational position of the rotary actuator 51 is automatically controlled within a predetermined region. The voice coil motor of the rotary actuator 51 does not generate torque outside the automatic control region, and the rotary arm 55 is rotated by the cam gear of the disk apparatus loading mechanism 70 to be described later. Locking in a rotational position.

In addition, in this embodiment, although the stainless steel is used as the material of the mounting plates 57a and 57b and the suspensions 58a and 58b using magnesium alloy as the material of the rotary arm 55, mechanical strength, such as polycarbonate, It can be molded by a large engineering plastic or the like. In addition, the rotary arm 55 and the mounting plates 57a and 57b can be integrally formed from the same material.

The other end of the coil spring 88 is engaged with one of the regulating pins 89a, and the holder lock member 77 pushes the hydraulic part 77b to the pressing part 76a by the spring force of the coil spring 88. It is pressed in the direction of approach. Then, the amount of rotation of the holder lock member 77 is regulated to a predetermined position by the restricting pin 89a coupled to the arcuate groove 77d. The locking hook 77a of the holder lock member 77 is coupled to the coupling pin 24 in a state where the cartridge holder 16 is inserted into the mechanical chassis 17, whereby the cartridge holder 16 is locked. do.

Below the cartridge holder 16, a pop-up spring 78 made of a coil spring showing an example of the pressing member is disposed. The pop-up spring 78 is compressed in a state where the cartridge holder 16 is attached to the mechanical chassis 17, springed up and tilted by releasing the holder lock mechanism, and as shown in Figs. The front part of the cartridge holder 16 is lifted by the pressing force. Incidentally, the lift amount of the cartridge holder 16 is limited by the pop-up inhibiting plate 79 as the gaseous-phase control member. As the pop-up spring 78, not only this example but also spring materials, such as a leaf spring, can be used, and rubber elastic bodies, such as synthetic rubber, can also be applied.

The pop-up inhibiting plate 79 has a J-shaped longitudinal section, and a bearing member 79a is provided on the upper side thereof so as to be parallel to the cross-sectional direction. A shaft pin 79b is fixed to the bearing member 79a of the popup inhibiting plate 79, and the shaft pin 79b is rotatably supported by the support bracket 90. As shown in FIG. The support bracket 90 is fixed to the mechanical chassis 17 by fixing means such as mounting screws, so that the pop-up inhibiting plate 79 is vertically moved to the mechanical chassis 17 through the supporting bracket 90. It is mounted so that it can tilt to float.

As shown in Figs. 1 to 5, the pop-up inhibiting plate 79 is slidably coupled to the small-diameter portion 20a of the holder reinforcement shaft 20 described above with the hook portion 79c on the tip side. The pop-up inhibiting plate 79 restricts the tilting of the cartridge holder 16 to the upper side. As the tilting means of the cartridge holder 16, a means other than the cam mechanism can be applied in addition to the present embodiment. For example, a cylindrical cam having a helically extending cam groove is rotatably installed in the mechanical chassis 17, while a cam pin that is slidably coupled to the cam groove is installed in the cartridge holder to rotate the cylindrical cam. By tilting the cam pin by tilting the cartridge holder.

Further, a lamp 91 for temporarily widening the interval between the pair of sliders 52a and 52b is disposed near the tip end of the rotary actuator 51 described above on the depth side of the mechanical chassis 17. The ramp 91 presses the ramp arm 92 inserted between the pair of sliders 52a and 52b and the back side of the rotary arm 55 to move the sliders 52a and 52b toward the cartridge side. 930 and the like. As the material of the lamp 91, for example, a synthetic resin material such as polyacetal (POM) is suitable, but other synthetic resin materials may be used.

A pair of insertion holes 91b and 91c formed in parallel with each other are drilled through the ramp 91, and the linear guide shafts 94a and 94b are inserted through these insertion holes 91b and 91c so as to be slidable. It is. The front and rear ends of the pair of linear guide shafts 94a and 94b are sandwiched from the top and bottom by the pair of front and rear bearing blocks 96 and the shaft pressing member 96a, thereby being fixed to the mechanical chassis 17 and both ends thereof. Supported. The lamp arm 92 is arrange | positioned above the middle part of these linear guide shafts 94a and 94b.

This ramp arm 92 is set on the movement trajectory of the convex parts 61a and 61b provided in the upper and lower suspensions 58a and 58b of the rotary actuator 51, and the pair of upper and lower sliders 52a and 52b are It is comprised so that the outer side of the lamp arm 92 may be moved. 9, the inclined surface 92a is provided in the upper and lower surfaces of the front-end | tip part of the lamp arm 92 so that the convex parts 61a and 61b may rise easily.

The coil spring 95 for urging the lamp 91 toward the spindle motor 12 is hung on a spring catching member 91a provided at one end of the lamp 91, and the other end is fixed to the mechanical chassis 17. It is caught by the spring support pin 97. Then, the forward movement of the coil spring 95 by the spring force is limited by the stopper pin 98 disposed between the pair of linear guide shafts 94a and 94b and fixed to the mechanical chassis 17. Doing. In addition, the amount of movement of the rotary actuator 51 in the direction away from the spindle motor 12 is limited by the stopper shaft 69 disposed on the rear side and fixed to the mechanical chassis 17.

In addition, a pair of positioning pins 80 and 80 and holder stoppers 81b and 81b are provided on both sides of the front portion of the mechanical chassis 17. Similarly, a pair of cartridge support pins are provided on both sides of the intermediate portion. 81a and 81a are provided. The positioning pin 80 and the cartridge support pin 81a are for positioning and supporting the disc cartridge 1 at a predetermined position, and the two support pins 81a are the head insertion holes 7 of the disc casing 2. While supporting both sides of the side from the lower side, the positioning holes 14a and 14b of the disc cartridge 1 are respectively inserted into the two positioning pins 80, whereby the planar direction of the disc cartridge 1 and Positioning in the vertical direction is performed. In addition, the two holder stoppers 81b are not inserted into the cartridge holder 16 so that the cartridge holder 16 does not enter the mechanical chassis 17 up to a predetermined amount or more. It is an overinsertion prevention member for the cartridge holder 16 for preventing it.

The disk drive mechanism 30, the shutter opening mechanism 40, the information recording / reproducing mechanism 50, and the disk loading mechanism 70 constituted as described above are incorporated. That is, as shown in Fig. 2, the cartridge holder 16 is inserted into the mechanical chassis 17, and the left and right support brackets 19 rotatably supporting the rear end of the cartridge holder 16 are positioned at predetermined positions. Stop the screw. Thereby, the cartridge holder 16 is supported to be tiltable in the up-down direction with respect to the mechanical chassis 17, and the cartridge holding part of the cartridge holder 16 corresponds to the upper side of the spindle motor 12 fixed to the mechanical chassis 17. do.

As described above, the disc recording / reproducing apparatus of the present embodiment is configured.

[4] operation of the disc recording and reproducing apparatus

Next, the operation of the disc recording / reproducing apparatus configured as described above will be described.

(4-1) Initial state of disc cartridge insertion

As shown in Fig. 2 and Fig. 4, in the state where the front portion of the cartridge holder 16 is lifted upward and popped up, the cartridge insertion port 18 is opened to allow the disc cartridge 1 to be inserted.

From this state, as shown in Fig. 16, the disc cartridge 1 is pressed into the cartridge insertion port 18 from the offset arc portion 6 side. At this time, the shutter release lever 41 of the shutter opening mechanism 40 provided in the side face of the cartridge holder 16 has a large tip portion of the input member 41b into the opening 23b by the spring force of the coil spring 42. As the reaction, the acting member 41c enters the opening 23a small. And the contact part 41d provided in the front-end | tip of the input member 41b of the shutter release lever 41 is located in front of the movement trace of the guide groove 10 provided in the side part of the cartridge holder 16. As shown in FIG.

At this time, if the operator accidentally inserts the disc cartridge 1 upside down, the shutter release lever 41 is provided on the side plate 16b on the side where the shutter release mechanism 40 of the cartridge holder 16 is installed. Since the erroneous insertion prevention convex part 26 bulged inward in the vicinity of the pin supporting members 43a and 43b which supports the swivelable part is provided, this erroneous insertion prevention convex part 26 is provided in the cartridge casing 2. Each part of the offset arc part 6 on the side 2d side without the guide groove 10 is in contact with each other. As a result, since the insertion of the disk cartridge 1 or more is prevented, the misinsertion of the disk cartridge 1 can be known in the middle of the insertion operation.

In this misinsertion state, the disc cartridge 1 is taken out, reversed up and down, and inserted again. Then, when the disc cartridge 1 is inserted in the up and down state, the misinsertion prevention convex portion 26 is inserted into the cartridge casing 2 even after the offset arc 6 reaches the position of the misinsertion prevention convex portion 26. Since it enters into the guide groove 10 of, the insertion operation of the disc cartridge 1 becomes possible further.

(4-2) The disc cartridge before shutter release

Next, as shown in Fig. 17, when the disc cartridge 1 is pressed and inserted deeply, the abutting portion 41d of the shutter release lever 41, which is largely inserted into the cartridge holder 16, is formed in the guide groove 10. In contact with the introduction portion 10c, the shutter release lever 41 is rotated clockwise in FIG. 17 against the pressing force of the coil spring 42 by being pressed against the inclined surface of the introduction portion 10c. As a result, the contact portion 41d of the shutter release lever 41 enters into the wide portion 10a of the guide groove 10, and at the same time, the action member 41c of the shutter release lever 41 moves to the guide groove 10. It enters into the operation part 10d. Then, the operation member 41c is guided to the inclined surface 10e of the upper or lower portion and guided to the narrow portion 10b, and enters into the operation hook of the shutter member 4 located at the front portion of the narrow portion 10b. (4f).

(4-3) After opening the disc cartridge shutter

Further, as shown in Fig. 18, when the disc cartridge 1 is further pushed and inserted to a predetermined position, the movement of the disc cartridge 1 is restricted by the stopper members 22a and 22b on the left and right sides of the cartridge holder 16. The hard disk HD accommodated in the disk housing chamber 3 corresponds to the upper side of the spindle motor 12 of the disk drive mechanism 30.

At this time, the operating hook 4f of the shutter member 4 is pressed against the acting member 41c of the shutter release lever 41 of the shutter opening mechanism 40 so as to be after the narrow portion 10b of the guide groove 10. Moving to the end, the shutter member 4 is rotated clockwise in FIG. 17 about the point axis 2f. As a result, since the shutter plate 4a and the core opening and closing plate 4b of the shutter member 4 move in the same direction, the head insertion opening 7 and the core opening and closing which are closed by the shutter plate 4a until then. The center core hole 9 which was closed by the board 4b is opened. Thus, the insertion operation of the disc cartridge 1 to the cartridge holder 16 is completed.

(4-4) Initial state of hard disk loading

2 and 4, the front portion of the cartridge holder 16, from which the front portion protrudes, is pressed against the pressing force of the pop-up spring 78 from the mechanical chassis 17. As shown in FIG. Accordingly, the cartridge holder 16 is inserted into the mechanical chassis 17 so that the two positioning pins 80 of the mechanical chassis 17 are disposed in the pair of right and left positioning holes 14a and 14b of the disc cartridge 1. The disk casing 2 is mounted on the two cartridge support pins 81a while being guided to the cone portion 80a to be coupled to each other.

As a result, the disc cartridge 1 supports the front portion by the two cartridge support pins 81a, and at the same time supports the rear portion by the two positioning pins 80, thus lowering the four corners. At the same time, positioning in the height direction and positioning in the horizontal direction of the disc cartridge 1 are simultaneously performed.

At this time, the center core 11 of the hard disk HD accommodated in the disc cartridge 1 is sucked by the magnet of the spindle motor 12. As a result, the hard disk HD is attracted to the spindle motor 12 and integrally formed in the rotational direction. By driving the spindle motor 12, the hard disk HD is driven to rotate integrally.

Further, as shown in Fig. 19, the cartridge holder 16 is press-fitted into the mechanical chassis 17, whereby the operation start switch manually operated by or after the operation of the operation switch provided to cooperate with this press-in operation. By the operation, the drive motor 71 is driven to rotate. The input gear 73a, the intermediate gear 82a, and the output gear 82b are rotated from the worm wheel 73 in which the rotational force of the pin 72 fixed to the rotary shaft by the start of the drive motor 71 is engaged. It is transmitted from the gear portion 74a to the cam gear 74 through.

At this time, the rotation actuator 51 of the information recording and reproducing mechanism 50 is extruded to the outside of the disc cartridge 1 by the action of the cam gear 74, and the mounting plates 57a and 57b are provided. The upper and lower sliders 52a and 52b attached to the tip of the rotary actuator 51 bent in a chevron form correspond to the outside of the head insertion opening 7 opened by the retraction operation of the shutter plate 4a.

That is, the outer end of the cam protrusion 55b provided on the rotary arm 55 of the rotary actuator 51 is in contact with the cam circumferential surface 74b of the cam gear 74, and the stopper is outside the rotary arm 55. Since the shaft 69 is located, the rotary actuator 51 is locked by being fitted by them. In addition, since the lamp 91 is tensioned to the spindle motor 12 side by the spring force of the coil spring 95, and the lamp arm 92 enters between the upper and lower suspensions 58a and 58b, as shown in FIG. Similarly, the convex portions 61a and 61b of the suspensions 58a and 58b are widened in the direction in which the sliders 52a and 52b are spaced apart from each other. And since the lamp 91 is in contact with the stopper pin 98, the movement to the front surface side is prevented by this.

Moreover, the cam pin 84 couple | bonded with the cam groove 74c of the cam gear 74 is located in the outermost peripheral part of the cam groove 74c. Therefore, the eject lever 76 having the cam pin 84 at one arm tip is in a position as shown in Fig. 19, and the pressing portion 76a provided at the other tip is a holder lock of the holder lock mechanism. It is spaced apart from the hydraulic part 77b of the member 77. Then, the cartridge pressing pin 87 provided at the tip of the eject lever 76 and the eject arm 86 integrally is located outside the rear of the disc cartridge 1.

(4-5) Status during hard disk drive loading

As shown in Fig. 20, when the cam gear 74 is rotated slightly in the clockwise direction by the drive of the drive motor 71, the spring force of the coil spring 95 is pressed against the rotary actuator 51 by the lamp 91. Since it is always input from the part 93, the counterclockwise pressing force acts on the rotary actuator 51 by the spring force of this coil spring 95. As shown in FIG. As a result, the cam projection 55b of the rotary arm 55 winds up the cam action end 74e provided at one end of the cam circumferential surface 74b of the cam gear 74 to enter the cam relief portion 74d. The actuator 51 is rotated counterclockwise.

As a result, the upper and lower suspensions 58a and 58b provided at the rotary end of the chevron rotary actuator 51 enter the head insertion opening 7 of the disc cartridge 1, and the upper and lower sliders 52a and 52b mounted at the leading end thereof. Accesses the outer periphery of the hard disk HD. At this time, since the cam pin 84 of the eject lever 76 is located at the outermost circumference, such as the cam groove 74c of the cam gear 74, the change in the attitude of the eject lever 76 and the eject arm 86 does not occur. It does not occur

In this case, the length (hereinafter referred to as " slider rotation radius ") from the rotation center O of the rotation arm 55 to the center of the sliders 52a and 52b is SR and the rotation center O of the rotation arm 55. From PR to the length of the suspensions 58a and 58b to the centers of the convex portions 61a and 61b (hereinafter referred to as the "convex rotation radius"), the sliders 52a and 52b come into contact with the lamp arm 92. The slider rotation radius SR is set to be larger than the convex rotation radius PR so as not to (SRPR). Therefore, the sliders 52a and 52b do not interfere with the lamp arm 92 within the rotation range of the rotary actuator 51, so that the sliders 52a and 52b are damaged due to contact with the lamp 91. Can eliminate concerns. In addition, since the upper and lower suspensions 58a and 58b are cut out of a part of the inner ribs 58a ₁ and 58b ₁ to provide a cutback, the ribs 58a ₁ , 58a ₂ and 58b ₁ and 58b ₂ are further provided. The strength of each suspension 58a, 58b can be reinforced with a rib, and can be set to an appropriate thing without concern.

(4-6) Loading status of hard disk drive

By rotating the cam gear 74, as shown in Figs. 21 and 22, when the cam protrusion 55b of the rotary arm 55 completely enters the cam relief portion 74d of the cam gear 74, While rotation control of the rotation actuator 51 by the cam gear 74 is released, automatic control by the voice coil motor composed of the drive coil 56 and the magnet 37 is started. Accordingly, the loading of the hard disk HD is completed, and the upper slider 52a is opposite to the upper surface of the hard disk HD, and the lower slider 52b is opposite to the lower surface.

As a result, the upper and lower sliders 52a and 52b are slightly lifted from the surface of the hard disk HD due to the aerodynamic effect of the rotation of the hard disk HD, and the hard disk HD is lifted in the injured state. The sliders 52a and 52b are movable in the radial direction. Thereby, the magnetic head 8 provided in each slider 52a, 52b moves on the information recording surface of the hard disk HD, and this magnetic head 8 carries out the data signal previously recorded on the information recording surface. Information is read and reproduction is executed, or information recording is performed to newly record a data signal on the information recording surface.

In this case, the rotary actuator 51 of the present embodiment has a chevron shape, and the suspensions 58a and 58b and the mounting plates 57a and 57b on the front end side enter and exit in a direction substantially perpendicular to the head insertion opening 7. Therefore, the width of the head insertion port 7 can be made small. Therefore, the head insertion opening 7 which is most likely to infiltrate into the disc cartridge 1 can be made as small as possible, and the intrusion of dust can be reliably prevented or the intrusion can be effectively suppressed. Since the disc cartridge 1 has a structure in which the offset arc portion 6 is provided at the front end side thereof, the space in the mechanical chassis 17 can be effectively used as compared with the conventional rectangular disc cartridge.

(4-7) Unloading status of the hard disk drive (when the cartridge is ejected)

After the recording or reproducing of information, or at the time of recording or reproducing, if a command to eject the cartridge is instructed by the operation of the eject operation button (not shown), the speed control of the voice coil motor of the rotary actuator 51 is performed. As a result, the distal end side of the rotary arm 55 moves to the outer circumferential side of the hard disk HD, and as shown in Figs. 23 and 9, the suspensions 58a and 58b lift and unload the lamp arm 92. Thereafter, the drive motor 71 is driven to rotate in the reverse direction, so that the cam gear 74 starts to rotate in reverse with the disc loading.

As a result, as shown in Fig. 24, the cam gear 74 is rotated counterclockwise, so that the cam action end 74e of the cam gear 74 is counterclockwise to the cam protrusion 55b of the rotary arm 55. In contact with the rotation, the rotary actuator 51 is rotated clockwise about the rotation axis 54. As a result, the cam protrusion 55b rides up the cam circumferential surface 74b of the cam gear 74, so that the rotary actuator 51 changes to the original posture shown in Fig. 24 (see Fig. 19). At the same time, since the pressing part 93 of the lamp 91 is pressed against the back side by the counterclockwise rotation of the rotary actuator 51, the lamp 91 is moved to the back side against the pressing force of the coil spring 95. Retract Move and lock to the unloaded state.

In this case, the length (hereinafter referred to as "arm length") from the rotation center O of the rotation arm 55 to the tip ends of the sliders 52a and 52b is referred to as SL and the rotation center O of the rotation arm 55. If the length (hereinafter referred to as "compression length") to the contact portion between the cam working end 74e and the cam protrusion 55b is PL, the rotary arm 55 is retracted to move the sliders 52a and 52b to retract the head. When positioning at the position, the pressing length PL from the acting position of the cam working end 74e which presses the cam projection 55b to the rotation center O becomes longer than 1/3 of the arm length SL. Therefore, since the rotation arm 55 can be rotated by pressing the part farther than 1/3 of the arm length SL, the enlargement ratio of the displacement amount of the arm by a cam can be made small, and the rotation control can be performed precisely. have. In addition, in this type of disk storage device, the compression length is 1/5 to 1/10 of the arm length, and the arm side is greatly displaced according to the minute displacement on the cam side, so that it is difficult to achieve precision for rotation control.

Moreover, in the voice coil motor which performs rotation control of the rotation arm 55 in this way, the part superposed | polymerized with the magnet 37 of the drive coil 56, ie, the left and right edge parts 56a, 56b of the drive coil 56. Torque occurs at As shown in Fig. 21, the side edge portions 56a and 56b of the drive coil 56 generate a large torque when located inside the N pole and the S pole of the magnet 37, but any one side edge portion When 56a and 56b are caught by the center line MC of the magnet 37 (the boundary between the magnets of the N pole and the S pole), the torque is drastically lowered, which adversely affects the performance of the rotation control.

On the other hand, according to the present embodiment, as shown in Fig. 23, when the sliders 52a and 52b are on the outer circumference of the hard disk HD, both side edge portions 56a and 56b of the drive coil 56 are formed. Since both are not caught by the center line MC of the magnet 37, the torque can be transmitted reliably without causing a torque down, and the rotating arm 55 can be rotated by a predetermined amount. Then, both side edge portions 56a and 56b of the drive coil 56 move without crossing the centerline MC of the magnet 37, and as shown in Fig. 22, the sliders 52a and 52b are hard to move. Even when moving to the innermost circumference of the disc HD, since both edge portions 56a and 56b are not caught by the center line MC, no torque down occurs. Therefore, according to this rotation actuator 51, in the area | region where automatic control by a voice coil motor is needed, the rotation arm 55 can be rotated precisely and precisely, without making a torque down in all the ranges. .

At this time, when returning to the state of FIG. 19 through FIG. 20 or going to the state of FIG. 24 via the state of FIG. 23, in either case, one side edge portion 56a of the drive coil 56 is the center line MC. ) And torque down, and as shown in FIG. 25, one side edge portion 56a moves over the center line MC and moves to the same side with the other side edge portion 56b, and the rotating arm ( 55) and the ramp 91 are in a fully retracted state, the voice coil motor does not generate any torque at all, but since the movement here is performed by the cam of the cam gear 74, the torque down is a problem It doesn't happen.

At the time of retraction of the rotary arm 55, the lamp 91 is retracted by the retraction operation of the rotary arm 55, and the lamp arm 92 is discharged from the head insertion port 7. In this case, since the two straight guide shafts 94a and 94b supported in parallel with the mechanical chassis 17 are inserted through the insertion holes 91b and 91c of the lamp 91 so as to be slidable, the both sides are guided linearly. Guided to shafts 94a and 94b, ramp 91 retreats linearly. In addition, the retraction operation | movement of the lamp 91 can also be set as the structure which moves two guide axes as a curved axis to circular arc shape.

Next, since the cam pin 84 of the eject lever 76 moves from the outermost part of the cam groove 74c of the cam gear 74 to the innermost part, the eject lever 76 moves the point shaft 85. Rotate clockwise around the center. Accordingly, on the one hand, the pressing portion 76a of the eject lever 76 contacts the hydraulic pressure portion 77b of the holder locking member 77 of the holder lock mechanism, and against the spring force of the coil spring 88, the holder The lock member 77 is rotated counterclockwise.

As a result, the locking hook 77a of the holder lock member 77 is separated from the engaging pin 24 of the cartridge holder 16, and the locked state in which the cartridge holder 16 is held horizontally with respect to the mechanical chassis 17. Is released. As a result, while the front part of the cartridge holder 16 is lifted by the spring force of the pop-up spring 78, the small diameter part 20a of the holder reinforcement shaft 20 hypothesized by the cartridge holder 16 was raised. It is limited by the pop-up inhibiting plate 79 to which the hook portion 79c is coupled. As shown in Figs. 2 and 4, pop-ups of a predetermined amount or more are prevented and returned to the original state. By appropriately changing the length of the hook portion 79c of the popup inhibiting plate 79, the tilting amount of the cartridge holder 16 can be set arbitrarily.

At the same time, the ejection arm 86 is rotated in the same direction in conjunction with the eject lever 76, so that the cartridge pressing pin 87 provided at the tip end thereof from the rear side to the offset arc portion 6 of the disc cartridge 1. Contact. Then, the disc cartridge 1 pressed against the holding plates 16d and 16e side of the cartridge holder 16 by a pair of left and right pressing leaf springs 25 is moved forward by the pressing force of the eject arm 86. Extruded. As a result, as shown in Fig. 25, the grip groove portion 2h side of the disc cartridge 1 projects only a predetermined amount from the cartridge insertion port 18. As shown in Figs. Therefore, by holding and pulling out this grip groove 2h, the disc cartridge 1 can be easily taken out from the cartridge holder 16.

At this time, for example, when a device breaks down or a user attempts to prevent the ejection operation by pushing the disc cartridge 1 by hand, a large resistance force is exerted on the eject arm 86 which extrudes the disc cartridge 1. Since the eject arm 86 is formed of a plate-like spring member, the resistance force is absorbed by the elastic deformation. Therefore, failure of the apparatus due to excessive ejection operation of the disc cartridge 1 can be prevented, and smooth ejection operation can be ensured. In addition, since the pop-up operation of the cartridge holder 16 and the ejection operation of the disc cartridge 1 are performed by one ejection member in which the eject lever 76 and the eject arm 86 are integrated, this kind of operation is simplified. And reliably, operation reliability can be improved.

Next, an embodiment example of a disc recording / reproducing apparatus showing the second embodiment as the disc storage apparatus of the present invention will be described with reference to FIGS. This second embodiment is applied to an elevator type disc recording and reproducing apparatus in which a cartridge holder holding a disc cartridge inserted in such a manner that the disc cartridge is inserted into a slot is lifted and mounted.

The disc recording and reproducing apparatus 200 has a disc driving mechanism, a shutter opening mechanism, an information recording and reproducing mechanism, and a disc cartridge mounting mechanism as in the first embodiment, but with the disc driving mechanism 30 and the shutter opening mechanism 40; Since the information recording and reproducing mechanism 50 is the same as in the first embodiment, the same reference numerals are given to the main components of these mechanisms 30, 40, and 50, and the description thereof is omitted and the disc loading mechanism 201 is described in detail. Explain.

The disc loading mechanism 201 of the disc recording / reproducing apparatus 200, as shown in Figs. 27 to 32, includes a cartridge holder 203 which is supported by the mechanical chassis 202 so that it can be lifted up and down.
