摘要： This invention relates to an automatic staining apparatus for staining many slide specimens such as tissue specimens by dipping them sequentially into a large number of chemical solution containers while they are mounted in a slide holder basket.Conventional automatic staining apparatuses have a problem in the staining efficiency because a basket is attached manually to a clamp member of the apparatus, and also have another problem that remaining chemical solution cannot be sufficiently removed from slide specimens.In order to solve these problems, an automatic staining apparatus according to the first present invention has the clamp member which can automatically engage with, and disengage from a basket, so that the staining efficiency is much improved. Preferred embodiment of the invention has a tilting mechanism for the clamp member, so that chemical solution is sufficiently removed from slide specimens.Another automatic staining apparatus according to the second invention has n (an integer of 2 or more) clamp members, each of which is characterized by the same as the first invention, and (n-1) relay stations inside the apparatus, so that a basket can be relayed automatically from one clamp member to another inside the apparatus and staining can be carried out for maximum n baskets at same time and independently from each other. Therefore, the rate of operation of staining apparatus is substantially maximum n-times. Preferred embodiments of the second invention also has a tilting mechanism for each clamp member, so that chemical solution is suffieciently removed.
