Abstract: A drinking water server includes a raw water storage unit that stores raw water containing chlorine and a cover that defines an inner space of the raw water tank by blocking an upper opening of the raw water tank; a purification unit that receives and filters the raw water and discharges the filtered raw water as purified water into a purified water tank which stores or discharges purified water in response to closing or opening of the purified water discharge path; a drinking water storage unit in which a drinking water discharge path is provided and which stores or discharges purified water in response to closing or opening of the drinking water discharge path by a float valve body based on an amount of the purified water by floating on the purified water, an inner space of the drinking water tank (40) being closed; and an air tube portion that communicates between the raw water tank and the drinking water tank.

Abstract: The present invention provides a displacement detector for a relative displacement of a fixed member and a movable member, which includes a first member and a second member. The first member is secured to the fixed member and composed of an insulator. The second member moves relative to the fixed member, integrally with the movable member. The second member is disposed opposite to the first member. The second member is composed of an insulator. Either of the first member and the second member includes an IC tag for detection performing non-contact communication, and the other includes a blocking member composed of a conductor blocking the communication performed by the IC tag. When the second member moves a predetermined amount relative to the first member, starting from an initial state, the IC tag for detection moves from inside to outside a region of the blocking member or vice versa.
