Abstract
A slat winding and unwinding control device of window blind includes flexible snap fit portions that are provided on the base to engage directly into the upper beam so that the mounting of the base into the interior of the upper beam is easy. A cord spool is designed to be capable of continuing its rotation in a fitting member so that there is no limitation on the winding direction of the pull cord. Moreover, the fixing of either a connecting strap or a connecting string for connecting each slat of the window blind on a housing member is very easy. Therefore, easiness and handiness in operation can be improved in the overall implementation of the system.
