PROBLEM TO BE SOLVED: To provide a pulse measuring device capable of accurately measuring a pulse rate even when body motion of a subject to be measured is frequently generated.SOLUTION: A pulse measuring device comprises: a pulse wave signal acquisition section for detecting a pulse wave of a subject to be measured by a pulse wave sensor 15 and acquires a pulse wave signal indicating pulsation a body motion signal acquisition section for detecting body motion of the subject to be measured by an acceleration sensor 33 and acquires a body motion signal including an acceleration component a rest period detection section for detecting a rest period which is included in a predetermined analysis object period on the basis of both of the pulse wave signal and the body motion signal and substantially has no body motion of the subject to be measured and a pulse rate calculation section for finding a pulse rate of the subject to be measured on the basis of the pulse wave signal acquired within the analysis object period. When the rest period detection section detects the rest period within the analysis object period, the pulse rate calculation section finds the pulse rate on the basis of the pulse wave signal only which is acquired within the rest period in the analysis object period.COPYRIGHT: (C)2016,JPO&INPIT【課題】被測定者の体動が頻繁に発生するような状況においても精確に脈拍数を測定することができる脈拍測定装置の提供。【解決手段】被測定者の脈波を脈波センサ15によって検知して脈動を表す脈波信号を取得する脈波信号取得部と、被測定者の体動を加速度センサ33によって検知して加速度成分を含む体動信号を取得する体動信号取得部と、脈波信号と体動信号との両方に基づいて予め定められた解析対象期間に含まれ被測定者の体動が実質的に無い期間である安静期間を検出する安静期間検出部と、解析対象期間内に取得された脈波信号に基づいて被測定者の脈拍数を求める脈拍数算出部と、を有し、安静期間検出部が前記解析対象期間内で前記安静期間を検出した場合、脈拍数算出部は前記解析対象期間のうち当該安静期間内に取得された脈波信号のみに基づいて脈拍数を求める、ことを特徴とする脈拍測定装置。【選択図】図3
