The present invention provides an elevator diagnosis device which can easily perform measuring operation for operation likelihood of a detection unit and can perform measuring even when a cage is lifted. The elevator is provided with a door (1A) provided on the cage (1), and a motor (6) which drives the door (1A). The elevator diagnosis device is provided with the following components: a door switch (3) which is provided on the elevator and detects a door closing state of the door (1A), an encoder (7) which is equipped on a shaft end of the motor (6) and transmits a pulse signal correspondingly with the driving of the motor (6), a counting part (10) which receives the pulse signal of the encoder (7) and counts, and a determining part (12). The determining part measures the action likelihood of the door switch (3) which is corresponding with a displacement of the door (1A) between the time when a door closing state of the door (1A) is detected and the time when the door (1A) is stopped based on a counting number after the counting of the counting part (10), and compares the measuring result with a preset value which is taken as an appropriate action likelihood for determining whether the door closing state of the door (1A) is abnormal. |
