Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a disc lift mechanism for safely and reliably storing and taking out a disc from a container that accommodates a plurality of discs in parallel during a hard disc manufacturing process.

(Prior Art) In a hard disk manufacturing process, it is common to store disks in parallel in a cassette case that is open at the top and bottom and has a partition groove on the inner surface as a disk storage container. A lifter is usually used to store or take out disks one by one in the cassette case. That is, when taking out, only one disc is pushed up by the lifter from the lower opening of the cassette case and taken out from the upper opening. Then, at the time of storage, the disc is placed on the pawl of the lifter that has been pushed up from the bottom and lowered along the partition groove of the cassette.

At that time, scratches, stains, etc. may occur due to contact between adjacent disks or between a lifter and an adjacent disk, which is a problem.

Especially when taking out an arbitrary one of a plurality of discs stored in parallel or when storing one disc in a place where there is a space for one disc, the method cannot be used, and the above problem is further reduced. It will be remarkable.

(Problems to be Solved by the Invention) In order to eliminate the above-mentioned adverse effects, the present invention provides a disk lift mechanism which prevents contact with an adjacent disk and enables the desired disk to be taken out or stored safely and reliably. The purpose is to provide.

(Means for Solving the Problems) In order to solve the above problems, the present invention comprises a cassette case having upper and lower openings and a partition groove formed on the inner side surface for accommodating disks in parallel, and a lifter that moves up and down to push up the disks. In a disc lift mechanism to be used, a disc guide having an opening for guiding a lifter, a mountain-shaped structure for supporting a disc to be pushed up, and a valley-shaped structure in which a trough for supporting and guiding a disc adjacent to the disc is provided near the disc. The present invention provides a disc lift mechanism characterized by using.

(Operation) Since the present invention is constructed as described above, it is used as follows in its use. That is, when taking out the disc, the disc guide is slightly pushed up at a desired position immediately before pushing up the lifter. The disc to be taken out is supported by the chevron structure of the disc guide and is lifted just below. Adjacent disks on both sides of the disk are not only supported and lifted by the valley-shaped structure of the disk guide, but also the valley is provided near the disk so that the lower edge of the disk approaches the disk to be ejected and the upper edges of the disks are close to each other. It will move slightly in the direction away.

If the lifter is moved up and down in this state, not only the disc is accurately positioned with respect to the lifter by the disc guide, but also the gap between the adjacent discs increases upward, so that the discs or the lifter and the disc are separated from each other. The contact can be avoided, and the desired disc can be taken out safely and surely without the occurrence of scratches or stains.

If the disc is to be stored in a space where there is one disc, the procedure is the reverse of the above procedure. That is, the disc guide is slightly pushed up to widen the interval between the adjacent discs, and the lifter is pushed up to place the disc on the pawl of the lifter, and the disc guide is lowered after the lifter is lowered along the partition groove.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the embodiments shown in the drawings.

3 to 5 show a conventionally used disc lift mechanism. Reference numeral 10 is a cassette case that can accommodate a plurality of disks in parallel, and has an upper opening 11 and a lower opening 12.
And a partition groove 13 is formed on the inner side wall. The lower opening 12 is somewhat narrower than the upper opening 11, and the partition groove 13 is also narrower downward accordingly, so that the disk can be supported.
FIG. 4 shows a state in which several discs are stored, and FIG. 5 shows a state in which a desired disc is pushed up by a lifter. 14a is a desired disk to be taken out or stored, and 14b and 14c are disks adjacent to it.
The lifter 15 has a valley-shaped tip and is capable of holding one disc by itself.

The above is the cassette case and the lifter which have been conventionally used, but the disc lift mechanism of the present invention also uses the disc guide 16 shown in FIG. First
7A is a plan view of the disc guide 16, FIG. 8B is a sectional view taken along the line AA ', FIG. 8C is a sectional view taken along the line BB', and FIG. The disc guide 16 is used for the cassette case 10 and the lifter.
As with item 15, it is desirable that the disc be made of a material that does not easily scratch. The disc guide 16 has an opening 17 at the center thereof, and the lifter 15 can be moved up and down through the opening 17. Therefore, although the size of the opening 17 is somewhat larger than the size of the lifter 15, by making the gap smaller or making the disc guide 16 thicker, the disc guide 16 simply moves the disc. Not only will it lead to, but will also have the effect of leading the movement of the lifter.

The disc guide 16 comprises a ridge structure 18 for supporting the desired disc to be removed or stored and a trough structure 19 for supporting and guiding the adjacent discs.

FIG. 2 shows how a disc guide 16 is used to remove or store a disc. FIG. 2 (a) shows a state in which the disc guide 16 is arranged directly below the desired disc,
FIG. 2 (b) shows a state in which the disc guide 16 is lifted slightly upward. In FIG. 2B, the mountain-shaped structure 18 of the disk guide 16 lifts the disk 14a upward, and the valley-shaped structure 19 of the disk guide is the disks 14b and 14c.
Are spread apart from each other at the upper edge of the disc. By vertically moving the lifter 15 in this state, the disk 14a can be taken out and stored safely and securely. The lifter 15 moves up and down relatively large, while the disc guide 16 moves up and down only in a narrow range, and if the disc guide 16 rises too much, it will cause distortion of the disc. It is desirable to limit the movable range by providing sensors, stoppers and the like.

Although FIG. 2 shows an embodiment in which there are adjacent discs on the left and right sides of a desired disc to be taken out or stored, the disc guide is firmly held and the disc is opened even when the left and right are unbalanced. By adopting a supporting method that can move up and down with the part 17 facing vertically,
It can also be used when there is an adjacent disk on either the left or right side.

(Effect) By implementing the disc lift mechanism characterized by using the disc guide, which is the point of the present invention, the space between the disc and the adjacent disc at the time of taking out or storing the disc is expanded, and the movable range of the lifter. The two effects of narrowing the contact are obtained, thereby achieving the object of the present invention to prevent contact and thus prevent scratches and stains.
