Is located directly above the sample pressing table 27 of the feeding device 20, and the groove 11a is located immediately below the opening 22a of the bracket 22. As described above, the case main body 11 is attached to the feeding device 20 by using the hinges 11f and 11g. Therefore, it is not necessary to use another attaching means (for example, a bolt) or the like, and the attachment can be performed with one touch. At this time, the storage state of the test piece TP can be confirmed from the long hole 12a provided in the lid 12.

Thereafter, when the motor 25 of the feeding device 20 is rotated by a predetermined amount in a predetermined direction, the rotation is performed by the screw rod 23 via the gears 24a and 24b.
And the screw rod 23 rotates. As a result, the sample pressing table 27 rises by a predetermined amount through the notch 11d and the opening 11c of the case main body 11, and the plurality of test pieces TP stacked in the groove 11a are pushed up by the sample pressing table 27 and integrally formed. Ascending, the uppermost test piece TP reaches the upper part of the bracket 22 through the opening 22a. At this time, the uppermost test piece TP is positioned by the positioning member 29 which is positioned at a predetermined position (position for positioning the test piece) in the direction in which the test piece TP is pushed up. Thereafter, after the cylinder 28 is contracted to retract the positioning member 29, the vacuum pad 40 is lowered to adsorb the test piece TP, transported to a material testing machine (not shown), set and tested. By repeating the above operation, the feeding and the test of the test piece TP are continuously performed.

During this test, other test piece storage cases
The test pieces TP are stacked and stored in the storage case 10, and when all the test pieces TP in the previous storage case 10 have been fed, the new storage case 10
In this case, the test need only be interrupted for the time required to replace the storage case 10, and the replacement can be performed in a short time, so that the test can be performed more efficiently than before. The same effect can be obtained by stacking and storing the test pieces TP in the plurality of storage cases 10 before the test.

In the above description, the case main body 11 is hinged using the hinges 11f and 11g.
Although an example of positioning and mounting the test piece feeding device 20 is shown, the invention is not limited to the hinge, and for example, a member having a projection provided on the case main body 11 has a concave portion provided on the feeding device side.
