PROBLEM TO BE SOLVED: To provide a biological data measuring instrument 10 capable of omitting the troublesome work of having a user input height in a body composition analyzer of a type provided with a grip electrode part 11.SOLUTION: The biological data measuring instrument 10 includes: the grip electrode part 11 which can be held by a person P to be measured and are integrally provided for both hands a mounting measurement part 13 connected with the grip electrode part 11 by a cord 12 a distance measuring mechanism 21 for measuring a distance between the grip electrode part 11 and the mounting measurement part 13 using an infrared ray transmission part 22 and an infrared ray reception part 23 an estimation part 24 for estimating the height of the person P to be measured from the positive correlation of a middle finger dactylopodite height B23 and the height H on the basis of the distance and a body composition calculation part 25 for obtaining a value relating to the body composition of the person P to be measured by utilizing the height H of the person P to be measured and data measured by the grip electrode part 11 or the like. The measurement is executed at a prescribed position so that the grip electrode part 11 is at the front of the body of the person P to be measured and is not brought into contact with the body except both hands.COPYRIGHT: (C)2009,JPO&INPIT【課題】グリップ電極部11を有するタイプの体組成計において、ユーザに身長を入力させるという面倒な作業を省くことができる生体データ測定器10を提供する。【解決手段】生体データ測定器10は被測定者Pが把持可能なグリップ電極部11であって両手用に一体に設けられたものと、グリップ電極部11とコード12により接続された載置測定部13と、グリップ電極部11と載置測定部13との間の距離を赤外線送信部22と赤外線受信部23とを用いて測定する距離測定機構21と、上記距離に基づき中指指節高B23と身長Hとの正の相関関係から被測定者Pの身長を推定する推定部24と、被測定者Pの身長Hとグリップ電極部11等により測定されたデータとを利用することにより被測定者Pの体組成に関する値を求める体組成計算部25とを備えている。測定はグリップ電極部11を被測定者Pの体の前方且つ両手を除く体に触れない所定の位置で行う。【選択図】 図1
