Abstract: A fluid distribution valve which selectively distributes a fluid supplied from a fluid supply source to a plurality of flow channels, includes first and second branch pipes communicated with the fluid supply source; and a valve body selectively closing either one of the two branch pipes, and including a through hole allowing a circulation of the fluid into the second branch pipe from the fluid supply source in a case wherein the first branch pipe is closed. While the valve body closes the first branch pipe in an initial state thereof, the valve body is displaced or deformed according to a pressure difference of the fluid in the a first branch pipe side and the a second branch pipe side when the fluid is supplied from the fluid supply source so as to open the first branch pipe, and to close the through hole.

Abstract: Contact terminals (24 and 26) are arranged on a support base (12) at a distance in a circumferential direction of a rotating drum (14). A conductive part (30) extending at least for a distance between the contact terminals (24 and 26) in the circumferential direction is provided on a perimeter surface (14A) of the rotating drum (14) in correspondence with the positions of arrangement of the contact terminals (24 and 26). The rotating drum (14) is rotated in the circumferential direction in a state in which the perimeter surface (14A) has been brought into contact with the contact terminals (24 and 26), and the conductive part (30) is brought into contact with the contact terminals (24 and 26), whereby switching between conducting and non-conducting is performed.
