To provide a power window controller which can open a windowpane even in a state that a rotary signal ceases to be generated by providing an open switch, a closing switch, a motor, a rotational detection sensor, and a control unit.
This power window controller is formed of an open switch 2, a closing switch 3, an automatic switch 4, an ignition switch 5, an electric source 50, a motor 6, a rotational detection sensor 7, and a control unit 20. The unit 20 is provided with a constant voltage circuit 21, a reset circuit 22, a drive circuit 23, and a microcomputer cpu. When a fall command signal of the switch 2 is given when a pulse signal is not given from the detection sensor 7, the current of the electric source 50 is given to the motor 6 in accordance with the signal. Hence, even when the sensor 7 is submerged and no pulse signal is detected, the current of the electric source 50 is imparted to the motor 6 in accordance with the fall command signal. In this way, the windowpane can be opened.
