Abstract

PURPOSE: To provide an automatic door, which is equipped with means for compensating the frequency change of power source for motor, whereby it is enabled to open and close the door always at an appropriate speed through control of the door driving speed.
CONSTITUTION: At least one of output pulley 3 of motor 2 and input pulley 5 of speed-reducing means 4, both disposed in transom 1, is arranged such that its effective pulley diameter can be varied, and a speed-reducing belt 6 is passed around the two pulleys 3, 5. Further, a driving belt 9 is passed around a drive pulley 7 of speed-reducing means 4 and driven pulley 8 associated therewith, and door 10 is suspended from the driving belt 9. With such an arrangement, it is enabled to compensate the frequency change of power source for motor 2 by changing the effective pulley diameter of said one of the pulleys 3 or 5 whose effective pulley diameter is arranged to be variable.
