PURPOSE: To avoid causing the convulsionary movement of a door during its open and close or reverse movement. CONSTITUTION: An elevator cage 1 includes a door 2 driven by a door driving device 9 comprising a motor 3, a first timing belt 4, a second timing belt 5, a driving roller 6, a first deflection roller 7 and an incremental transmitter. The motor 3 is supplied with electric unit 12 of a door control device 11. The incremental transmitter driven by the first deflection roller 7 is connected to the second interface 10 of a microcomputer 13. An algorithm implemented by the movement curve computer 14 of the microcomputer 13 runs to control the door driving device 9. A constant required for a procedure is freely selected, and then communicated to the algorithm by a terminal unit. The movement curve computer 14 works to communicate an aimed-value of the door position and its present value to a regulator 17 for controlling the power source unit 12. |
