A motorized window blind operator is slidably received in a mounting bracket in the plane of the blind in a window frame. A motor in the operator housing normally opens and closes the blind but can be overridden by a manually operated gear train utilizing a screw driver extending through a hole in the inner window pane into engagement with a slotted hub on a gear in the housing. An upstanding flange on the housing overlaps with the adjacent blind slat to prevent light passing therethrough when the blind is closed. The housing has a V-shaped vertical end which receives the ends of the blind slats which have a similar shape for preventing light passage therebetween.
