Abstract
In an elevator apparatus, an operation control section controls an operation of a car. Further, a safety monitoring section detects an abnormal state of targets to be monitored during running of the car to stop the running of the car. A safety-monitoring-function inspection section inspects a function of the safety monitoring section. The safety-monitoring-function inspection section causes the safety monitoring section to detect a transition of a state of the targets to be monitored to the abnormal state regardless of an actual state of the targets to be monitored while the car is running under control of the operation control section.
