The invention relates to a gear skipping detection device of a passenger conveyor. The gear skipping detection device comprises a motor; an input shaft of the speed reducer is connected with a rotating shaft of the motor; a plurality of steps connected in a ring shape; the step chain wheel is used for driving the steps; the first chain wheel and the step chain wheel are coaxially arranged; the annular driving chain is erected between an output chain wheel of the speed reducer and the first chain wheel; the handrail driving wheel is driven by the step chain wheel; the handrail driven wheel and the handrail driving wheel are driven by clamping a handrail belt; a first speed sensor outputting a first pulse signal corresponding to a first rotational speed of the input shaft; the second speed sensor outputs a second pulse signal corresponding to a second rotating speed of the armrest driven wheel; and a control unit that detects the skipping of the output sprocket on the basis of the second pulse signal output during a period in which the first pulse signal having a predetermined number of pulses is output.
