Title:
POWER WINDOW DEVICE
Document Type and Number:
Japanese Patent JP3211928
Kind Code:
B2
Abstract:
PURPOSE: To improve safety by providing a mechanism for determining whether or not a count value correspons to the position for the opening and closing of a window glass, and a movement control mechanism for stopping the revolution of a motor in the closing direction of the window glass either when a fixed time has passed, or when the window glass has been moved in a fixed amount after start of the motor to the closing direction on the basis of the result of the determination.
CONSTITUTION: Output is conducted once per revolution from a sensor of a pulse generator synchronously with the revolution of a motor 11. When a window glass is moved to a completely closed place and a count value must be set to zero when the count value obtained by up-down counting the number of pulses of a pulse signal PA in the first and second positional counter areas in response to the direction of rotation of the motor 11 reaches a value which does not correspond to the place of the opening and closing of the window glass 51, the revolution of the motor 11 is stopped for a fixed time or stopped facing on the amount of movement by operating a switch 3. Accordingly, the window glass having a posibility of catching a foreign matter can be moved safely in the closing direction.
