Abstract: Disclosed is an automatic tissue microarray apparatus that includes: a sample module being drivable and providing a space for mounting at least one donor block and at least one recipient block; an extract module being drivable in at least two directions and having at least one punching tip for punching a tissue from the at least one donor block and arraying the punched tissue in the at least one recipient block; and a controller for controlling the driving operations of the sample module and the extract module and, in response to an externally applied command, the punching and arraying operations of the extract module. The present invention securely provides convenience in use with improved work efficiency and contributes to precision of punching and arraying operations.
