PERSON-TRANSPORTING APPARATUS HAVING SPEED-MEASURING DEVICE

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). 本发明涉及一种人员运送设备(1)，其具有用于驱动和转向传送带(26)的至少一个驱动链轮(17)，以及具有用于检测驱动链轮(17)的转速的至少一个检测装置(20)。在所述驱动链轮(17)的至少一个环形侧面(35)上布置有狭缝形的内凹(37)，其中，狭缝形的所述内凹(37)的纵向伸展参照所述驱动链轮(17)的
