Patent ID: 7979116

Claim:
A body composition measuring instrument comprising: a plurality of electrodes configured to be contacted to a surface of a body of a user; a first calculating unit for calculating a body composition of the user by using the electrodes; a storage section for storing information of a reference value related to a past body composition of the user; a display control unit determining a position of a body composition calculated for a measurement time during which a current body composition of the user is measured and a position of the reference value calculated by the first calculating unit on a predetermined graph; and a display section providing a display corresponding to an output from the display control unit; wherein the position of the reference value is a predetermined fixed position in the predetermined graph; the reference value corresponds to a body composition calculated by the first calculating unit at a specific time point in the past; the display control unit includes: a first determining unit for determining a display mode of a component in the predetermined graph corresponding to the body composition for this time based on the body composition for this time and the reference value, a second determining unit for determining a range of values of the body composition displayable on the predetermined graph based on the reference value; and the first determining unit determines the display mode based on the range determined by the second determining unit.
