A curtain reel device with rolling up and down spring motor using pull cords to take-up and let-down a horizontal blind set of the blinds. A take-up and let-down motor installed in the interior is provided with a self-feedback operation that operates pull cords for taking up and letting down blinds. A simple coil spring is installed with a reel device, and the inner circumference of a reposition coil formed by the coil spring directly forms an inner annular hub with a fixed diameter by coiling up the end of an elastic sheet band. The inner annular hub is mounted on a pivot shaft joined to side walls to enable movable free rotation thereof. The inner annular hub is in a separation rotational speed relationship with an idler gear coaxially assembled to one end of the pivot shaft, thereby simplifying the structural components of the reel device.
