Abstract
A controller writes position information (count value) of the window glass into an EEPROM based on halting of operation of a drive motor and identifies the current position of the window glass based on the position information of the window glass written in the EEPROM at the start of power supply. The controller determines whether the current position of the window glass has been lost or not at the start of power supply. Only when the controller determines that the current position of the window glass has been lost at the start of power supply, the controller shifts to a mode of performing relearning of the origin position for matching the position of the window glass with the position of the window glass corresponding to the position information written into the EEPROM.
