Publication number: 20190381515Abstract: A magnet is disposed close to and outside a container held by a container holding part, and relatively moves along the container, so as to move the magnetic particles in the container by a magnetic force. A housing accommodates the magnet and the container holding part in the housing in a state where a position of the magnet relatively moving along the container is not visually recognizable from the outside. A display unit is provided on the housing so as to be visually recognizable from the outside and has light emitting regions that can emit light. A processing step execution unit sequentially executes a plurality of processing steps by relatively moving the magnet. When the plurality of processing steps are sequentially executed, a light emission control unit causes the light emitting regions to emit light according to a position of the magnet.Type: ApplicationFiled: May 2, 2019Publication date: December 19, 2019Applicant: SHIMADZU CORPORATIONInventors: Akira MURAMATSU, Masamitsu SHIKATA, Ayaka YAMANO
