The invention relates to a person-transporting apparatus (1), which has at least one drive sprocket (17) for driving and deflecting a transport belt (26) and at least one sensing apparatus (20) for sensing the rotational speed of the drive sprocket (17). Slit-shaped cut-outs (37) are arranged on at least one annular side surface (35) of the drive sprocket (17), wherein the longitudinal extent of the slit-shaped cut-outs (37) extends over the annular side surface (35) in the radial direction with respect to the center of rotation of the drive sprocket (17). By means of the sensing apparatus (20), a signal representing the rotational speed of the drive sprocket (17) can be produced by scanning the slit-shaped cut-outs (37), which can be moved relative to the sensing apparatus (20), and scanning the elevations (36) present between the slit-shaped cut-outs (37).
