Abstract (en)
[origin: EP3281899A1] Provided is a sheet material end detection mechanism including: a sheet material information part indicating information on a sheet material wound around a core member in which a light passing part is formed; a reader configured to optically read the sheet material information part; and a detection unit configured to detect that the sheet material is used up, wherein a forming part is attached to an outer surface of the core member and an inner surface of the sheet material, the sheet material information part is formed in a portion of the forming part corresponding to the light passing part, adhesive force between the sheet material and the forming part is larger than adhesive force between the core member and the forming part, and the detection unit is configured to detect that the sheet material is present when a read signal of the sheet material information part read by the reader is received and that the sheet material is used up when the read signal disappears, during the operation of withdrawing the sheet material.
