A specimen processing system according to the present invention includes a plurality
of specimen processing units each having flat sides and a specimen operating surface
and operated singly. The specimen processing units have at least the same depth
dimension, and the specimen operating surfaces of the specimen processing units
have the same height dimension. The system further includes a coupling section
for closely coupling the right and left sides of the specimen processing units
to each other and a single driving control unit for controlling a related operation
of all of the specimen processing units coupled to each other by the coupling section
and a single operation of a designated one of the specimen processing units.
