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.
A method for controlling a door opening and shutting operation of an automatic door apparatus including steps of, memorizing a door opening and shutting stroke value measured at a setting time of the automatic door in a non-volatile memory, and reading out the door opening and shutting stroke value memorized in a memory for the door stroke value of a micro-computer 12 after power is supplied, a memory method for memorizing the door opening and shutting stroke value of said automatic door comprising the steps of: opening and shutting a door at a low speed to measure the door stroke value when the door opening and shutting stroke value is not memorized in said non-volatile memory each time the power is supplied to the automatic door apparatus; memorizing the door stroke value in said memory for the door stroke value of said micro-computer as the door opening and shutting stroke value; calculating the shut side and open side door stroke values in opening and shutting said door at a low speed to measure the door stroke value; and determining the measured stroke value as the door stroke value when both stroke values are about equal to each other.
