Provided herein is an integrated wireless patch comprising a contact layer, an electronics layer, and a battery layer. This tampon comprises a generally elongated absorbent member and an overwrap substantially covering the exterior surface of the generally elongated absorbent member, wherein the overwrap is fluid wicking and has an Agar Shear Force of no more than about 90 grams per inch of material width. The controller performs the control such that a moving speed of a shift moving unit is reduced when a shift amount of the sheet discharged from an image forming apparatus main body is small.
