DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disk drive device for rotating a flexible magnetic disk called a floppy disk. A conventional floppy disk sliding device places the center of the disk on a disk rotating support that is rotated and slid by a motor, presses the disk against the disk rotating support with a clamper, and connects the disk rotating support and the clamper. It is configured to rotate the disk by holding the disk between the two. The clamper is rotatably supported on the side opposite to the general κ disk insertion opening, and is disposed under an arm or cover that is rotated κ in the disk direction against a biasing spring. and is configured to engage the disk rotation support.

Therefore, the operation of locking and releasing the disc rotating support member 9 of the clumber must be performed in multiple directions, and the disc drive device inevitably becomes thicker. Also,
In a disk drive device of the type in which the clamper is engaged with the disk rotating support by pressing the top cover, it is possible to arrange multiple disk sliding stands of the same type one on top of the other, or place them on top of the disk drive device. It was not possible to place another device or object. Furthermore, there is a problem in that it is difficult to easily judge the condition of the clumper inside the container from the outside. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disk drive device that can clearly determine whether a disk is held or not held and has good operability.

The present invention, which achieves the above object, includes a motor for rotating a recording medium disk, and a motor K coupled to the motor to rotate following the rotation of the motor and supporting the disk. a nine-disk rotation support formed therein; and a disk non-holding position where the disk can be attached to and detached from the disk rotation support, the disk is moved from a disk non-holding position to a disk holding position, and the disk is pressed to the disk rotation support. a disk holding device that fixes and rotatably holds the disk; a suspension device that applies a biasing force to the disk holding device in the direction of the disk non-holding position; and a round opening for attaching and detaching the disk. a container for accommodating at least the motor, the disk rotation support, the disk holding device, and the biasing device; an operating knob that is in a non-covering position that does not block the opening, and a shielding position that covers at least a portion of the opening during a disc holding operation; The present invention relates to a disk sliding device characterized by comprising an interlocking mechanism provided between the disk holding device and the disk holding device.

According to the above-mentioned version 1jH'c, since the disc holding operation knob is provided on the surface having the disc insertion opening, it is possible to hold and release the disc, and to attach and detach the disc with a single operation surface. This makes it easier to handle the disc-driven scissor holder. In addition, when the operation knob is in the disc holding state, at least a part of the disc insertion opening is covered, and when the disc is not being held, it does not cover the opening, so it is possible to clearly judge whether the disc is held or released. I can do it. In addition, it is possible to prevent the disk from being forcibly pulled out or inserting another disk by mistake while the disk is in the disk holding state κ.

The lower surface of the disc assembly (to) is formed in the same way as the upper surface. Also, the jacket 19K has a rounded cutout (to) to prevent accidentally writing another recording onto a recorded disc. is provided. The disk holding device (c) for holding the disk a81 includes a clumper (c) and a rotary arm five fins as a support for the clumber (to), as shown in FIGS. 2 and 3. Consists of #! The broom can be moved between the disk holding position shown in Figure 2 and the disk non-holding position shown in Figure 3. The rotating arm fin receives a biasing force in the disk non-holding direction shown by the arrow (C) due to the plate panel as a biasing device provided at one end (27aJ) and the base body aυ. ) is the shaft ({IK) of the other end (27b) of the forehead of the rotating arm. A force is given to it.This clamper (to) has a through hole (211

It has a retaining part (1) with the moving operation mechanism shown in FIG. , rotation of the arm ■ by the spring @ is blocked at this position.
As shown in the figure, a long and narrow disk insertion opening is provided. The opening surface is shown on a reduced scale in Figure 9.
The rotary support (II
5K is arranged so that the support man is almost the same. The operation surface cl6lvc has a disk holding operation knob, that is, an operation lever. The fulcrum of this operation knob (to) is fixed to -tlK of the rotation shaft, and corresponds to the disk non-holding position of the disk holding device (c) shown in Fig. 4K.
Take the open low non-shielding position shown in FIG. It is formed to take . As can be seen from FIGS. 6 to 8, this operation knob has a 5K disk insertion operation section tune.

This disk insertion operation part 1 has nine parts that protrude in the disk insertion direction, and has an inclined surface t4ut' such that the amount of protrusion decreases as the distance from the axis increases. If the jacket 0 with the disk aa is inserted securely up to the stop flange (6) shown in Fig.
If the insertion of the disk assembly ① in the state shown in Fig. 4 κ is incomplete as shown in Fig. 7, the operating knob ( ) is turned clockwise in 4 directions, the slanted surface 1D hits the edge of the jacket Nil, and following the rotation of the operation knob, the position of the slanted surface 1D relative to the jacket (19tc) changes,
Is jacket 0 yen? llIrc is pushed in, and the final position is as shown in Figure 8.

The interlocking mechanism for transmitting the operation of the operating knob (to) to the disc holding scissors is rotatably supported by a set of 4 bearings mounted on the frame, as is most obvious in Figure 6. A rotary wheel with an operating knob (G) fixed to one end, an arm fixed in the shape of a crank to the other end of this shaft, a bottle 4 installed in the crank shape of this arm, and a bottle 4 attached to this arm. A ghM consisting of nine rotating plates (41) that are engaged and one end of which is rotatably supported by a fixed shaft, and a retaining part decoy consisting of nine bottles that is fixed to the same rotating plate as well as the bolt part.
To explain the interlocking mechanism in more detail with reference to FIGS. 10 to 12, the rotating shaft 1 is connected to the operating knob 1, that is, the fulcrum κ of the operating lever.
It is fixedly fixed and extends in the disk insertion direction shown by arrow 1, and is arranged parallel to the insertion plane of the disk assembly (2). The arm is fixed to the shaft extending from the frame to the right to form a crank arm, and extends parallel to the operating knob.

The pin (C) is placed at a position that serves as a crank pin with respect to the shaft 4. That is, the pin protrudes at right angles from the surface opposite to the fixed surface of the rotating wheel (to) in the arm fin, and is arranged so that its center does not coincide with the center of the axis, and the disk is inserted in the direction shown by the arrow. It's growing. Frame C34
Rotation 11 (4?), which is fixed to JK and rotatably supported by the fixed shaft 1K, is a retaining surface of the bottle (c) consisting of the inner circumferential surface of the slot extending along its longitudinal direction. The arm 44410 is arranged so as to rotate in a plane perpendicular to the disk insertion direction, following the rotation of the arm 44410, that is, the change in the angular position of the crank bin 4. The retaining surface of slot 6110 pin 4 is such that the pin 4 does not move until the straight line connecting the center of the axis and the center of pin 4 becomes almost parallel to the plane containing the movement locus of the disk holding device (c). Formed to forgive, 10,
As shown in Figure 12, the κ slot group is formed so that the straight line connecting shaft 4 and pin 4, that is, the direction in which the arm extends, almost coincides with the vertical direction indicated by arrow 61l. Furthermore, the sut group is provided with a rounded depression (Sea) that performs a click operation. The tip of the rotary plate (mK) is provided with a 9-hook part 1, which consists of a bottle that protrudes in the 10,000-way direction for inserting the disc, as shown by arrow 4, and includes a disc holding device (c).
It is supported by the protruding retaining part Q on the side and engaged with the nine-shaped part 11K. The six pieces shown in Figure 6 are each in color. Referring again to Figures 1 through 3, the magnetic head as a converter for recording and reproduction and the parts attached thereto will be briefly explained. Since this floppy disk drive is a double-sided recording and reproducing type, it has a $1 magnetic head that contacts the top surface of the disk a● and a second magnetic head that contacts the bottom surface. In both cases, a carrier 6eK is attached to receive the feeding of the disk Ql in the radial direction. The transporting member (G) is guided by two guide rails 6TlK extending in the radial direction of the disk Qs, that is, the insertion direction κ of the disk a8, and moves in the radial direction of the disk a●. Furthermore, this carrier ω is #! As shown in Fig. 1, the feed is coupled by the rack ω and the pinion 1t), and moves according to the drive of the motor. The lower head (G) is supported by the Jin Pal Panel II and is directly attached to the carrier ω, while the upper head (B) is fitted with a spring in order to enable the attachment and detachment of the disk assembly (A). Upward K at 13
Biased arm fi3! It is installed with κ Jinparpane. Further, an arm 61K protrusion 1 is provided so that the head support arm 1 moves in the direction K of the disk non-holding position in conjunction with the movement of the disk holding rotary arm (2).
This protrusion 1 extends above the rotating arm ■. The head support arm is biased by the panel in the direction K in which the head (B) comes into contact with the disk QIK, so in order to selectively control the rotation of the head support arm 10 in the direction of the disk aυ, the protrusion is One extends above the leper, which is driven by a planjean.

When inserting the disk assembly ■, this is the lower head f.
In order to prevent BK collision, this is a disc guide lever with a nine U-shaped cross section, and is supported by the shaft II at the U-shaped cross section. It is biased to move downward. Then, the retaining piece σ°C fixed to the rotating arm 50IK corresponds to the disc non-secure position and reaches the high 1 position as shown in the JIIZ diagram, and at 9 o'clock the tip of the retaining piece n resists the spring fflK. push up one end of the lever 17) and guide the disk assembly guide (681) to the position shown in FIG.
In the case of the disk holding state, the disk assembly guide portion (6813) moves downward κ relative to the jacket (19) as shown in FIG.

Next, we will discuss how to attach and detach the disk assembly 1 and its operation. When the disk assembly 4 is not inserted and the disk holding device (c) is in the non-holding state, κ is shown in Fig. 2, Fig. 4, and #! As shown in Fig. 10, the operating knob extends horizontally in all directions] IIK, and the clamper (to) is spaced apart from the disk rotating support Ql, so that it is in a nine-shape IIIc. Since the five faces of the rotating arm are biased by the spring in the direction shown by the arrow (to) in Figure 2, the engaging part 1 consisting of the pin is pushed upward by the engaging part RO at the tip of the arm. As a result, the rotating plate ρη is offset counterclockwise as shown in Figure 10, and the arm and operating knob are moved almost horizontally as shown in Figure 10. In this state, as shown in Fig. 4, the opening Clη
Since the operating knob (to) is not layered, the disc assembly ■
It is possible to insert . Therefore, insert the disk assembly (to) as shown in Figure 9k into the opening (b) from its right end first. First, insert the 5K disk assembly (A) horizontally as indicated by arrow 1 in the figure. At this time, it is not possible to insert the disk assembly ■ to the final position shown in Figure 2, and only the length L of the rear tin of the disk assembly remains as an uninserted part, as shown in Figure 11. Sometimes. but,
If the length L of the uninserted part is small, the disc assembly (7) will be automatically moved to the final position by the disc holding operation.
is inserted. In other words, since the operation knob (to) is provided with the disk insertion operation part 1 having an inclined surface [(4υ), when the operation knob @t-1] is turned K counterclockwise as shown in the figure, the inclined surface υ By pressing the rear edge of the disk assembly (7), the disk assembly (A) is pushed into the position shown in Fig. 12K.If the uninserted length L of the disk assembly (■) is large, the operation Since the knob (to) hits the top surface of the disk assembly ■ and it is impossible to turn the operating knob (to) any further, it is immediately determined that the disk assembly (to) is incompletely inserted. The 9th disc will not be clamped incorrectly.If you turn the operating knob (up) @ from the state shown in Fig. 30 by approximately 90 degrees as shown in Fig. 12, it will follow the rotation of the operating knob (up). The crank arm also rotates about 90 degrees, and the moving mold (47) is pressed by the crank bottle μ gloss and rotates clockwise by a predetermined angle, and the retaining part (47) consisting of a bottle at the tip C) presses the engagement part of the rotating arm, and rotates the rotating arm counterclockwise κ against the biasing force of the plate panel (to);
Shaft part tzga of Kurareba (c)) Through hole 3υ of cutisque Ql and recess (151
The middle part of the disc (18aJ) is clamped between the flange-like part (26b) of the clamper (toward) and the support surface of the disc rotating support aO. The crank arm is held in place with the help of a locking mechanism, i.e. the crank arm is held in place with the help of a locking mechanism.
If it almost coincides with the vertical direction indicated by arrow 6υ in Figure I13,
Slot} 61m right @ flc The bottle (c) is inserted into the slight depression (501J), and the specified clamp operation is completed by the click operation. Even if the sensor is moved, this position K will be maintained.

This is because the bottle 4 and the shaft 1 are arranged on a vertical line, and the arm 141 is rotated fE@η by the biasing force κ caused by the leaf spring @k.
This is because almost all of the force applied to K becomes a component in the vertical direction shown by arrow 6υ, and almost no force is generated in the direction of turning the arm. The right end of the slot 61) is provided to limit the rotation angle of the bottle on the vertical line, so the crank arm will not rotate any further counterclockwise. Incidentally, instead of determining the angular position of the pin 4 by the suit 1G, a stopper may be provided to prevent the crank arm from turning counterclockwise beyond the vertical line.

If the disk Qυ installed as described above is a recorded disk and it is necessary to prevent the next recording,
In this device, an emitter (not shown) is provided on one side of the cutout shown in Figure 9, and a light receiving element (not shown) is placed on the other side. Arranged, optically notched■
Detects the presence or absence of , and displays this in display 1}ffa shown in figure l//L5. To release the clamper (28K) from holding the disc AL, turn the operation knob (to) clockwise as shown in Figure 12 and counterclockwise as shown in Figure 5.This will cause the crank arm to move #!] In Figure 2, it is possible to rotate clockwise, and by the biasing force of the leaf spring (to) and/or the operating force of releasing the operating knob (to), the rotation plate (4η is rotated counterclockwise in Figure 12). The rotation arm rotates clockwise, the clamp on the disk a8 is released, and the disk assembly (to) is pulled out at Illfl:K.As is clear from the above, the method of this embodiment includes the following steps. There are advantages.

(Al The operation knob (G) is the operation surface clb with an opening.
The operating knob (to) covers a part of the opening row when the disc is held so that it can be rotated seven times, so the operating knob (to) at 1 m (to) κ is arranged so that it can rotate freely. The shape mv of the disc holding device (c) can be easily determined by the position of the disc holding device (c). Also, there is a risk of accidentally inserting the disk assembly twice. Also, positioning of the opening 07) of the jacket }Q9 is achieved by the insertion operation part 1 of the operation knob (to).

b) Since the opening surface and the operation knob (to) are provided on the same operation surface 061, all operations can be performed with one @K. Therefore, not only is the operability good, but it is also possible to stack a plurality of disk drives or to place another object on top of this disk drive, which is convenient in terms of space.

(C) The operating knob @ is rotated, and the rotating arm is operated via a crank mechanism with four horizontally extending shafts, arms, and hinges, so the thickness of the container Q can be reduced. It becomes possible. (d) The straight line connecting the axle and bottle 4 is the vertical line on the disk Qe, that is, the vertical line Ii! Since the points scattered along I are used as the holding position of the disc bet, it is possible to maintain this position without providing a special locking mechanism using a hook. Therefore, the configuration is simplified.

(e) Since the operation knob @ is provided with a disk insertion operation part mt having an inclined surface (4υ), it is possible to prevent the disk assembly (to) from being in the uninserted state IIK. (holding the fl disk Qll) At this time, the operation knob (to) must cross the insertion path of the disk assembly (■), so when the amount of disk assembly (■) that has not been inserted is large, the operation knob (to) cannot be rotated. It was immediately discovered that the disc was inserted incompletely, and the disc A8 was inserted in the incorrectly inserted position.
There will be no situation where this happens. The above description has focused on the implementation of the present invention, but the present invention is not limited to this, but can be further modified. For example, it is also applicable that only the disk aa is inserted into the opening (9) without inserting the jacket 09K disk a8v. Furthermore, it is not limited to magnetic disks, but can also be applied to devices that drive disks that perform optical κ recording or reproduction. (9) A drive shaft inserted into the center hole of the disk is provided in the center of the disk rotating support QB to rotate the disk.
