PROBLEM TO BE SOLVED: To provide a conveying member positional change amount measuring device capable of accurately measuring the positional change amount of a conveying member using detection values obtained by detecting positional changes of the conveying member at predetermined time intervals while the conveying member is rotated one or more turns without depending upon the rotational frequency of the conveying member.;SOLUTION: This conveying member positional change amount measuring device includes the conveying member rotatably supported for conveying the body to be conveyed, a positional change detection means for detecting the positional change when the conveying member conveys the body to be conveyed, and a conveying member positional change amount calculation means which acquires the detection values detected by the positional change detection means at predetermined time intervals while the conveying member is rotated one or more turns, which performs the calculation of the averaged value of the detection values in one rotation of the conveying member to acquire a plurality of averaged values by delaying the predetermined number of predetermined time intervals from the initial detection value, and furthermore averages the averaged values to calculate the positional change amount of the conveying member.;COPYRIGHT: (C)2010,JPO&INPIT
