Abstract
A method and apparatus for preparing a microscopic specimen by lifting up coverslips in a piled state one by one, comprises a step of means for holding the upper-most coverslip on one spot on its upper surface and pushing the same on another spot on one end portion of its upper surface apart from the holding spot in a longitudinal direction of the coverslip. The holding spot of the coverslip is then lifted and, with a delay time; the pushing spot of the coverslip is lifted so as to bend the coverslip while it is held, within its elastic limit edge of the coverslip is then pushed downwardly to bend the coverslip and cause another coverslip which may be stuck to the bottom of the uppermost coverslip, to drop off. The curvature is then eliminated.
