ABSTRACT:
The door can be safely and exactly opened and shut even when the door opening and shutting stroke value is not memorized in the non-volatile memory. The door opening and shutting stroke value measured in the setting time of the automatic door is memorized in the non-volatile memory 14. Then, the memorized door opening and shutting stroke value is read in the plant memory 15 for the door stroke value of the micro-computor 12. In the automatic door for opening and shutting the door 5 according to the door opening and shutting stroke value, when the door opening and shutting stroke value is not memorized in the non-volatile memory 14 after the power supply, the door 5 is opened and shut at the low speed to measure the door stroke value. And the door stroke value is memorized in the plant memory 15 for the door stroke value of the micro-computor 12 as the door opening and shutting stroke value, and the door 5 is opened and shut in accordance with the memorized value.
