A sheet material depletion detection mechanism that is provided with: a sheet material information part that indicates information related to a sheet material that is wound onto a core member in which a light transmission part is formed; a reading part that optically reads the sheet material information part; and a detection part that detects when the sheet material has been depleted. A formation part is adhered to an outer surface of the core member and to an inner surface of the sheet material. The sheet material information part is formed at a section of the formation part that corresponds to the light transmission part. The adhesion between the sheet material and the formation part is greater than the adhesion between the core member and the formation part. During an operation in which the sheet material is drawn out, the detection part detects that there is sheet material when a reading signal that indicates that the reading part has read the sheet material information part is received and detects that the sheet material has been depleted when the reading signal is no longer received.
