The invention relates to a chain looseness detection device, which is a passenger conveyor capable of correctly detecting slack of a chain. The chain looseness detection device is provided with: a drive timing detection unit that detects operation timings, which are timings when a pair of sprockets on which a chain is wound actually start to rotate; and a control unit that determines that the chain looseness above a predetermined reference value is generated under the condition that the difference between the pair of operation timings detected by the drive timing detection unit exceeds a predetermined reference timing difference and is detected.
本发明涉及链条松弛检测装置,能够正确地检测链条的松弛的乘客输送机。该链条松弛检测装置具备:驱动定时检测部,分别检测卷挂有链条的一对链轮实际开始旋转的定时即动作定时;以及控制部,在由上述驱动定时检测部检测的一对动作定时之差超过规定的基准定时差并被检测到的情况下,判断为产生了规定的基准值以上的链条的松弛。
