The cooperative operation of both gripping branches 43 and 44 allows the perforated disk to be stably gripped here.

(Common supplementary information regarding each embodiment) In the present invention, as described later, both gripping branches 3, 4, 23, 24, 43 of an elastic member formed in a U-shape for handling a perforated disk are used. ,44
The inner shape of the tip plays an important role.

This will be further explained based on FIG. 4, which shows an enlarged view of the tip of the gripping branch of the first embodiment.
In order to proceed with handling most efficiently, the shape of the inner surface of each tip should be determined by making tangent lines along the outer edges of the curved parts that open outward from each other, and tangent lines that follow this along the trailing edges of the hooks that protrude inward from each other. It is desirable to make the angle θ ₁ +θ ₂ larger than the image-taking angle of the disk, and to maintain the inclination angles θ ₁ and θ ₂ with respect to the disk surface and the distance between the disk surface and the tip of the hook within the following ranges.

That is, θ ₁ ≧θ ₂ , θ ₁ −θ ₂ ≦20°, more preferably θ ₁ −θ ₂ ≦10°, and θ ₁ =30 to 60°, θ ₂ =25 to 60
°,
When the thickness of the disk is 1.5mm, = 3~6mm
It is.

(Operation of the invention) Next, the operation of the invention will be explained in the fifth section regarding the case where an aluminum disk is taken out from a magazine type disk case using the clamping tool according to the first embodiment.
This will be explained using figures.

In the magazine type disk case 60, the aluminum disks 20, 20, .
61... is housed inside with its edges supported.

To take out the aluminum disk 20 from the case 60, first remove the U provided on the vertical side wall of the case.
The clamping tool 1 is inserted through the letter-shaped outlet (not shown) with the gripping branch 3 facing upward, and as shown in FIG.
1 and 12 to the outer edge 62 of the aluminum disk 20, and the recess 16 provided on the inner surface of the tip of the gripping branch 4 to the inner edge 64 facing the hole 63 of the disk.
For this purpose, a method has been adopted in which the disks 20 are held one by one and taken out from the case 60.

As mentioned above, in operations using instruments, a situation often arises in which the instrument is inserted too deep, as shown in Figure a.

However, in the gripper 1 according to the present invention, the gripping branches 3,
The gripping tool 1 Even if the disc 20 is inserted too far into the back, the curved part will come into contact with the edge of the nearest disc 20, and the tips of the hook parts 9, 10, and 15, which are connected in a position that opens outward from this, will touch the other disc 20. ′
There is no risk of contact.

In addition, in order to narrow down the clamping tool 1 and clamp the disk 20 closest to you in this state, the curved portions 6a and 7
This becomes possible only when the gripping tool 1 is moved back along the outwardly opening curved surfaces of a and 14a and brought into the state shown in Figure b.

Therefore, in this invention, the front disk 2 is always
Since the other disks 20' are not caught and come out together with the disk 20 when only the disk 20 is held and taken out, the work can be carried out efficiently just by feeling the holding tool 1 against the disk 20.

(Supplementary information on configuration) The present invention is not limited to the above-mentioned embodiments, and the present invention can be implemented in other forms as well.

For example, in each of the above-mentioned embodiments, the tip of one gripping branch of the clamping tool is branched left and right and has two mutually symmetrical recesses, and together with the recess of the other gripping branch, the disc is formed in three recesses. Although a clamping tool of the type for clamping is shown, various other embodiments as shown in FIG. 6 are conceivable.

FIG. 6 shows only the positions of the recesses when the perforated disk is clamped using clamping tools having different numbers of recesses.

This figure a shows one in which one recess is formed in each of the two gripping arms of the clamping tool, and in figure b, two recesses are formed in one gripping arm and one in the other gripping arm, as in the previous embodiments.
Fig. c shows the other gripping branch in Fig. b with a wider recess, and Fig. d shows two recesses in each of the two gripping branches. In Figure e, one of the recesses that the outer edge of the disk touches in Figure A is made wider, and its inner surface shape is matched to the curvature of the outer edge. Conceivable.

In addition, gripping branches, side plates, or side branches that are provided parallel to each other in the direction of the disc and held in line contact with the edge of the disc at the edge of the recess, There are two types: one that is held in surface contact with the edge of the disk;

In the fields where contamination is averse, which is the subject of this invention, the less contact there is when using instruments, the less chance of contamination. In addition, from the viewpoint of workability, it is better to have a simple structure. On the other hand, in terms of operability for gripping and transporting the disk, the more points there are for support, the better. In summary, the configuration shown in FIG. b or d is the most preferable in order to achieve the above-mentioned objective.

(Effects of the invention) As described above, according to the clamping tool of the present invention, it is possible to prevent the disk from being contaminated or damaged due to incorrect operation of the fingertips or the instrument, and it is possible to prevent the disk from coming into contact with other disks. Since only one disk can be reliably held by the feel of the holding tool and moved in a stable state, the disk handling work can be carried out extremely efficiently.
