摘要：
A disclosed to-be-transferred object length measurement device includes a first rotating body; a passage detection unit detecting a passage of the to-be-transferred object; a rotation amount measurement unit measuring a rotation amount of the first rotating body in a first measurement period; a second rotating body feeding the to-be-transferred object; a speed detection unit detecting a first feeding speed and a second feeding speed of the to-be-transferred object; and a calculation unit calculating a feeding distance of the to-be-transferred object per a predetermined rotation amount of the first rotating body based on the first feeding speed, and further calculating a length of the to-be-transferred object based on the rotation amount of the first rotating body in the first measurement period, the feeding distance, and the second feeding speed of the to-be-transferred object in the second measurement period.
