Abstract

PURPOSE:To shorten the disk changeover time by adopting a plural multistage rotary shelf system and enabling a spindle motor, a head mechanism and a cone mechanism to be movable vertically and rotatively. CONSTITUTION:A sliding base 25 and a moving base 30 are moved up to the height of a target rotary plate 18 by a rotational driving source 39 and then rotated by the drive of the rotational driving source so as to be moved into a target rotary shelf 15. Simultaneously, the rotary shelf 15 is rotated by the drive of a rotational driving source 21 so that a target disk 10 is selected, thereby conforming the center of the disk 10 with the center of a spindle motor 26. Then, the sliding base 25 is ascended so that the spindle motor 26 lifts up the disk 10 to hold the disk 10 with the cone mechanism 31 between them, and then the disk 10 is rotated by the spindle motor 26 to carry out a read and write work for necessary information, and afterward, the sliding base 25 is descended again so that the disk 10 is brought back to its original recessed groove 17, while the moving base 30 is moved to the position of the next rotary plate 18 and then rotated. By this method, the disk changeover time can be shortened.

It consisted of a disk drive section that performs writing, and a transport mechanism that is disposed adjacent to the storage shelf section and the disk drive section and transports the disks between the storage shelf section and the disk drive section.

[Problems to be Solved by the Invention] In the conventional disk drive device described above, the storage shelf section and the disk drive section are fixedly arranged, so handling of disks between the storage shelf section and the disk drive section is difficult. A transport mechanism is required to carry out this process. In addition, since the transport mechanism handles the disks, the method of replacing the disk is that the transport mechanism returns the disk mounted in the disk drive unit to its original position on the storage shelf, then takes out the required disk and loads it into the disk drive unit again. A method is being taken to do so. Therefore, it takes a long time to replace the disk, and as a result, there are disadvantages such as an increase in the downtime of the disk drive unit.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems of the conventional art. A plurality of rotary plates having concave grooves for holding them at equal intervals are arranged vertically concentrically, in the same phase, and at equal intervals, and rotary shelves that can freely rotate about the concentric shafts are arranged in pairs and at a constant Arranged in parallel with a gap,
A sliding table on which a spindle motor and a head mechanism are mounted in the gap between these pairs of rotary shelves; a cone mechanism forming a sliding pair in a vertical direction with the sliding table and disposed above the spindle motor to face each other; The present invention provides a disk drive device characterized in that it is provided with a movable table that is vertically movable and that is rotatable around an end remote from the rotary shelf.

The feed screw 38 to be moved and these rotary shelves 15. Sliding table 25. Mobile platform 30. It includes a guide shaft 33 and a base frame 40 that supports a feed screw 38.

The rotating shelf 15 includes a plurality of rotating plates 18 and a plurality of rotating plates 18.
The rotary shaft 19 is connected and fixed vertically concentrically, in the same phase, and at equal intervals, and a rotary drive source 21 is concentrically connected to the upper end 20 of the rotary shaft 19 and driven to rotate. 15 are arranged in pairs with a gap in between.

The rotating plate 18 includes a plurality of disks lO having a center hole 11.
It is used to store objects, and is approximately disk-shaped. Further, a plurality of concave grooves 17 corresponding to the disks 10 are provided at equal intervals on the peripheral portion of the rotary plate 18.

The sliding table 25 is located approximately in the center of both rotating shelves 15.15,
On its upper surface, a spindle motor 26 and a disk 10 having a function of moving in the radial direction of the spindle motor 26 are provided.
A head mechanism 27 for reading and writing information between the two is mounted.

The moving table 30 forms a vertical sliding pair with the sliding table 25, and has a cone mechanism 31 disposed above the spindle motor 26 and facing each other at its tip. The width of the moving table 30 and the sliding table 25 is set to be smaller than the gap.

The guide shaft 33 forms a vertical sliding pair with the movable base 30 at an end 34 of the movable base 30, and its upper and lower ends are fixed to an upper plate 35 and a lower plate 36, respectively, and a rotary drive source 3 is attached to the lower end.
7 is connected and fixed.

The feed screw 38 is arranged parallel to the guide shaft 33 in a screw pair with the movable table 3o, and its upper end is connected to a rotational drive source 39.

The base frame 40c*, the upper and lower ends of the rotating shaft 19 and the lower end of the guide shaft 33 are rotatably held, and the rotational drive source 21.39 is fixedly held.

Next, the operation of the disk drive device according to this embodiment will be explained.

Figures 4 to 6 are front views showing the operating states, and Figure vJ4 shows the moving table 30 before and after moving up and down and turning, and Figure 5 shows the rotating shelf 15 rotating and the moving table 30 moving up and down and turning. FIG. 6 shows a state in which the desired disk 10 has been selected. FIG. 6 shows a state in which the disk 10 has been loaded.

1 to 4, when a command to start work is issued from the central control unit (not shown), the sliding table 25 and the moving table 3
0 is moved to the target height of the rotating plate 18 by the rotational drive source 39 via the feed screw 38, and then rotated by the rotational drive source 37 and moved into the target rotating shelf 15. At the same time, the rotary shelf 15 is rotated by the rotation drive source 21, and the target disk 10 is selected. At this time, the center of the disk 1o and the center of the spindle motor 26 match, resulting in the state shown in FIG. 5. Next, as shown in FIG.
5 is raised and the spindle motor 26 lifts the disk 10 and clamps the disk 10 together with the cone mechanism 31.
The disk 10 is rotated by a spindle motor 26. In this state, the head mechanism 27 operates to read and write necessary information. When the work is completed, the disk 10 stops rotating, the sliding table 25 descends again, and the disk 10 is returned to the original groove 17, and the moving table 30 is rotated back into the original gap. Next rotating plate 18
Move to the position and turn. At the same time, the desired rotating shelf 15 rotates to select a target disk, and by repeating the above operations, information is read from and written to the desired disk 10. By repeating this operation, all required information reading and writing operations can be completed.

[Effects of the Invention] As explained above, the disk drive device of the present invention has the following advantages:
Since it uses a multi-stage rotating shelf system, it has the advantage of being able to accommodate a large number of disks and store a large amount of information. In addition, since the spindle motor, head mechanism, and cone mechanism are structured to be able to move vertically and swivelly, a transport mechanism for handling the disk is no longer required, which has the effect of significantly simplifying the structure and reducing the weight of the device. be. Furthermore, since there is no need to handle the discs, the time required to replace the discs can be significantly shortened, making it possible to operate this fruiting device efficiently and maintaining high quality without damaging the discs. effective.
