There is disclosed an elevator speed control apparatus, in which a final signal representative of a traveling speed to be detected is determined by changing a first provisional signal depending on the traveling speed in accordance with a second provisional signal, when a difference between the two provisional signals exceeds a predetermined value; the first provisional signal being obtained on the basis of a pulse width of a pulse from a rotary encoder rotating with the travel of the elevator and the second one being obtained on the basis of a number of pulses in the pulse train for a predetermined sampling period. |
