Abstract: An electrophoresis device (analysis system) is an electrophoresis device that electrophoreses a sample in a capillary by applying a voltage to a pair of electrodes in a microchip (analysis tool) provided with the pair of electrodes at both ends of the capillary. The electrophoresis device includes: an installation unit installing the microchip, a first terminal and a second terminal respectively in contact with one and the other of the pair of electrodes of the microchip installed in the installation unit, a power supply device (voltage application unit) connected to the first terminal and the second terminal and applying a voltage in the capillary, and a terminal rotation unit (changing unit) changing a combination of electrical connections between the pair of electrodes, and the first terminal and the second terminal.

Abstract: An omni-directional rotational drive mechanism and a moving body in which production and maintenance can be facilitated, while the size can be reduced, by making the number of components smaller. A rotating body provided for a wheel member rotatable about a ring-shaped shaft having a rotating shaft of the wheel member as its center. The rotating body is configured to rotate integrally with the wheel member about the rotating shaft. A pair of worms rotatable about the same shaft as the rotating shaft of the wheel member. A pair of worm wheels are provided for the wheel member so as to be rotatable by meshing with different worms, and capable of transmitting each of rotations to the rotating body. The rotating body is configured so as to rotate or stop with respect to the wheel member in accordance with the rotational direction and the rotational speed of the respective worms.
