Abstract
A fibrous body accumulating device includes an accumulating section including a drum that introduces and releases a material including fibers, a detection section detecting a presence of the material in the drum, and an estimation section estimating an amount of the material in the drum based on a detection frequency at which the detection section detects the material. The fibrous body accumulating device further includes a storage section in which a calibration curve showing a relationship between the detection frequency and the amount of the material in the drum is stored, and the estimation section calculates information on the detection frequency and estimates the amount of the material in the drum with reference to the calibration curve.
