Patent ID: 7930021

Claim:
A body composition measuring apparatus comprising in a portable apparatus body: a first electrode to be contacted with one hand of a subject; a second electrode to be contacted with the other hand of the subject; a measurement portion that measures an impedance of a body of the subject using said first electrode and said second electrode; and a detection portion, wherein said apparatus body includes: a cylindrical first grip having said first electrode; a cylindrical second grip having said second electrode; and a display capable of displaying a body composition based on a measurement result measured by said measurement portion, said first grip and said second grip are disposed such that respective axis lines thereof are disposed to overlap with each other on the same straight line, said second grip is coupled, to be slidingly movable in a direction of the axis line thereof, to said first grip in a freely movable manner and is movable between a first position where measurement by said measurement portion is allowed by said body composition measuring apparatus and a second position where measurement by said measurement portion is not allowed by said body composition measuring apparatus, said display is exposed in a state where said second grip is at said first position, and covered with at least one of said first grip and said second grip in a state where said second grip is at said second position, and said detection portion is configured to detect whether said second grip is at said first position, and detection by said detection portion that said second grip is at said first position causes power to be supplied to said measurement portion.
