<p>PROBLEM TO BE SOLVED: To provide a handrail inspection device of a passenger conveyor capable of accurately inspecting bulge of a handrail with a simple structure.SOLUTION: A handrail inspection device of a passenger conveyor includes: a range measurement sensor scanning laser beam to the front face in a width direction crossing a direction in which a handrail is driven and obtaining a first distance up to the front face and two-dimensional distance data up to the front face of the width direction; a distance sensor which is provided to face the range measurement sensor across the handrail so as to obtain a second distance up to a rear face; and an arithmetic section performing a first determination to determine a change in the shape of the front face by performing a comparative analysis between front face shape data generated from the two-dimensional distance data and reference data set in advance, performing a second determination to determine an increase in thickness by performing a comparative analysis between thickness of the handrail obtained using the first distance and second distance and the reference data and determining bulge of the handrail on the basis of the first determination and the second determination.</p> |
