Abstract

PURPOSE:To ensure the complete loading of a disk with a simple constitution, by pressing the unloaded part of the disk with a slope of a disk loading control part provided to a disk holding control knob when this control knob is operated to hold the disk. CONSTITUTION:A disk 18 is held by turning a control knob 38. In this case, it is required for the knob 38 to cross the loading part of a disk assembled body 20. Thus the knob 38 is able to turn in case the unloaded amount of the body 20 is large, and this fact can be immediately known. The knob 38 has a disk loading control part 40 containing a slope 41. As a result, the disk unloaded part is pressed by the slope 41 and the disk is inserted up to a prescribed position. Furthermore the thickness of a container is reduced since a rotary arm 27 is controlled with a turn of the knob 38 and via a crank mechanism including a horizontal shaft 39, an arm 44, a pin 45, etc.

[Detailed description of the invention]

The present invention relates to a companion disk drive device for rotationally driving a flexible magnetic disk called a floppy disk. The conventional 7-view disk drive device places the center part of the disk on a disk rotation support that is rotationally driven by a motor, presses the disk against the disk rotation support with a clamper, and connects the disk rotation support and the clamper. The disc is configured to be rotated by holding the disc between the two. still,
The clamper is generally disposed on the lower surface of an arm or cover that is rotatably supported on the opposite side of the disk insertion opening, and supports the rotation of the disk by rotating the arm or cover in the direction of the disk against a biasing spring. configured to engage the body. However, mounting the disk assembly in a box-shaped jacket or enclosure into position is accomplished by inserting the disk assembly into an opening in the device container. However, there is a risk that incomplete insertion may occur, such as an uninserted portion. If the disk is held with a clamper while the disk is incompletely inserted, the disk may be damaged, or if the center of the disk does not match the center of the drive mechanism, the transducer and the track may be placed in a predetermined positional relationship. There was a fear that it would become impossible to maintain and perform recording or reproduction well. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a disk drive device that can reliably insert a disk or an assembly thereof with a simple configuration. To achieve the above object, the present invention includes a motor for rotating a recording medium disk, and a motor coupled to the motor so as to rotate following the rotation of the motor, and supporting the disk and rotating. the formed disk rotation support, and the disk is fixed to the disk rotation support by moving from a disk non-holding position to a disk holding position where the disk can be attached to and detached from the disk rotation support and pressing the disk. a disk holding device for rotatably holding the disk; a container having a round opening for attaching and detaching the disk and accommodating at least the motor, the disk rotation support, and the disk holding device; an operation knob that is disposed on a surface having the opening, that is in a non-shielding position where the opening V is obstructed when the disc is not held, and that is in a shielding position that blocks at least a part of the opening when the disc is held; When the operation knob is integrally formed and moved from the non-shielding position to the shielding position, the disc or the disc assembly including the disc is not completely inserted into the opening, and the disc is not completely inserted into the opening. If there is an insertion portion, a disk insertion operation portion having an inclined surface for pressing and inserting the uninserted portion in the insertion direction into the opening, and for interlocking the operation knob and the disk holding device. Nine interlocking gears are provided at the connection between the operation knob and the disc holding device. l! The present invention relates to a disk drive device characterized by comprising: According to the above-mentioned book @, the disc insertion operation part is installed in the rounding operation knob for holding the disc, so when the operation knob is operated to hold the disc, the uninserted part of the disc is moved by the inclined surface of the disc insertion operation part. It is pushed and inserted into the specified position. Furthermore, if the uninserted portion is too large to be inserted by the disk insertion operation section, the operation knob collides with the disk or its assembly, preventing the disk from being held. Therefore, the disc is prevented from being held with an uninserted portion.

Regarding the magnetic head and associated parts
Simply explain. This floppy disk drive is of a double-sided recording/reproducing type, and has a magnetic head #C in contact with the top surface of the disk O&, and a magnetic head #C in contact with the bottom surface of the disk. Disc (il)
It is mounted on a carrier to receive the radial feed of l. The carriage (G) moves in the radial direction of the disk Q8) guided by two guide rails 6η extending in the radial direction of the disk, that is, in the same direction as the insertion direction of the disk 0. As shown in Figure 1, this transport platform is coupled to a feed motor 1t) by a rack mallet and a pinion, and is moved in accordance with the drive of the motor. The lower head can is supported by a gimbal spring and is directly attached to the carrier ω, but the upper head (
(b) is attached to an arm 63 biased upward by a plate spring with a gimbal spring in order to make the disk assembly (b) removable. In addition, a protrusion is provided on the arm so that the head support arm moves in the direction of the disk non-holding position in conjunction with the movement of the disk holding rotating arm, and this protrusion rotates. It extends above the arm. Note that since the head support arm is biased in the direction in which the head contacts the disk a& by means of -p, in order to selectively control the rotation of the head support arm in the direction of the disk (181), , a protrusion extends above a lever driven by a Brangen-Renoid motor. 61 is a nine-point extension which prevents the disk assembly from hitting the lower head when inserted. The shaft I!1#IC is supported by the U-shaped section, and the disk assembly guide portion tssat is imfI1 moved downward by a spring σIVC. And the rotating arm (27) K
When the fixed holding piece σ is in the high position as shown in FIG. 2, corresponding to the disc non-holding position, the holding piece f is fixed.
Push up one end of the lever ■ against the spring ff1K with the tip of the fl, and guide the disk assembly guide part (68aJ-) to the position shown in Figure 2.In addition, in the disk holding state, the third
As shown in the figure, the disk assembly guide @ (68aJ is shake) (moves 11% lower than 19).Next, the method of attaching and detaching the % disk assembly (a) and its operation will be described.Disk assembly When (to) is not inserted and the disc holding device (c) is not held, the operation knob (to) extends horizontally as shown in Figures 2, 4, and 0. and the clamper (to) is in a state separated from the disk rotation support body aυ.
Since the surface of the rotating arm is biased in the direction shown by the arrow (c) in Figure 2 by the spring, the retaining part at the tip of the arm is
The holding part consisting of a bottle is pushed upwards by
The rotating plate 71 is biased in the direction of the counterclockwise hand in the WLlo diagram, and the arm and the operating knob @ are kept almost horizontal as shown in Figure 0. In this state, the opening (
9) Since the operation knob (to) does not cover the value, it is possible to insert the disk assembly (to). Therefore, the disk assembly shown in FIG. 9 is inserted into the opening Cη from its right end first. In other words, as shown by the arrow - in the figure J[], the disk assembly ■
Insert horizontally. At this time, it was not possible to insert the disk assembly ■ to the final position shown in Figure 2, and as a result, only the length L of the rear end of the disk assembly ■ remained as an uninserted part, as shown in Figure 1. It may remain. However, if the length L of the uninserted portion is small, the disk assembly (A) is automatically inserted to the final position by the disk holding operation. That is, since the operation knob is provided with a disk insertion operation having an inclined surface portion υ, when the operation knob is turned counterclockwise as shown in the figure, the inclination FIυ
presses the trailing edge of disk assembly ■, and disk assembly 0
1 word #! It is pushed into the position shown at 3211. 9. If the uninserted length L of the disc assembly (to) is large, the operating knob (to) will hit the top surface of the disc assembly ■, making it impossible to turn the operating knob (to) any further. Therefore, it is immediately obvious that the disk assembly (1) is incompletely inserted, and the incorrect clamping of the nine disks is prevented. Turn on the controls! # from the state shown in Figure 10! ] When the crank arm is turned approximately 90 degrees as shown in Figure 2, the crank arm will follow the rotation of the operating knob (to) and rotate approximately 90 degrees.

It turned out that the end was nine, and the operation turned out (to)
It will remain in this position even if the operating force is released. In this case, the bottle (C) and the shaft are arranged on a vertical line, and the leaf spring (C) is arranged on a vertical line.
This is because almost all of the force applied to the arm from the rotation Ik- due to the biasing force caused by (to) becomes a component in the vertical direction shown by the arrow 6υ, and almost no force is generated in the direction of rotating the arm (goods). be. Note that the right end of the slot is provided so as to limit the rotation angle of the bottle 4 on the vertical line, so
Do not allow the crank arm to turn any further counterclockwise. Incidentally, instead of determining the angular position of the pin 4 by the slot 611K, a stopper may be provided to prevent the crank arm from moving in the counterclockwise direction K beyond the vertical line. If the above-mentioned 9th disc is a recorded disc and it is necessary to prevent the next recording, please use the 9th disc.
A notch shown in the figure is provided. In this device, a light emitting element (not shown) is placed at the -10,000 @ of the notch, and a light receiving element (not shown) is placed at the other 1111.
The presence or absence of the notch @ is detected optically, and it is shown in Figure Ji35.
This is displayed on the display ffa. To release the disk Q#IF) from being held by the clamper (to), 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 as shown in Figure 5I32. The turning plate (471 is rotated counterclockwise in Fig. When the rotating arm is rotated clockwise, the crank of the disc (11) is released, and the disc assembly (7) can be pulled out.As is clear from the above, the method of this embodiment There are the following advantages: (a) Since the disk insertion operation part IIt having the operation knob (to) K and the inclined surface 1 is provided, the disk assembly (to) can be easily
There is no inserted letter! There are two things you can do to prevent IK. (b) When holding the disk retainer, the operating knob (to) must cross the insertion path of the disk assembly ■, so when a large amount of the disk assembly ■ is not inserted,
It became immediately obvious that the operation knob (to) could no longer be rotated, and it was immediately determined that the disk had been inserted incompletely, resulting in a situation where the disk (Ill) was clamped at the wrong insertion position. The knob has an operation surface (I[
9, and when the disk aSt' is held rotatably, the operating knob (to) partially covers the opening (V), so depending on the position of the operating knob on the operating surface (to), The state of the disc holding device (c) can be easily determined. In addition, there is no risk of accidentally inserting the disk assembly GIQ twice, and furthermore, the insertion operation part, which is an example of an operation knob, can be used to easily insert the disk assembly GIQ twice. The ipsilateral positioning of the opening of the tube H1 is achieved. (d) Since the opening (b) and the operation knob (to) are provided on the same operation surface C1619, all operations can be performed using the - surface. Therefore, the operability is not limited to JL- (

It becomes possible to reduce the thickness. (f) The straight line connecting axis - and bin 4 is 1 m perpendicular to disk [8, that is, vertical! Since the dead center coincides with I and is the holding position of the disc a, it is possible to maintain this position without providing a special locking mechanism such as a hook. Therefore, the configuration is simplified. Although the embodiments of the present invention have been described above, the present invention is not limited thereto and can be further modified. For example, jacket l! JK disk Q8) It is also applicable to a device in which only the disk AS is inserted into the opening (b) without inserting the Y. Also, without magnetic disk rc@,
It is also applicable to a disc tl-electrically driven device that performs optical recording or reproduction. Maku, disk rotating support σe
A drive shaft is provided in the center of the disk to be inserted into the center hole of the disk.
It is also applicable to devices that rotate disks. Furthermore, instead of rotating the operating knob, it may be configured to slide in the vertical direction.
