CONSTITUTION:Each door of a car is provided with a limit switch for detecting opening or closing of the door. A measurement starting instruction is sent from a control section 1 to measuring portions 2a-2h via a transmitting section 3, so that operating time of each door is measured in accordance with such signals as indicating the open state and the closed state of the door. After completion of the measurement, the measuring portions 2a-2h sends measured results to the contro section 1 via the transmitting section 3. The control section 1 performs totalization of the measured data and then displays 4 its result. |
