Disclosed is a pair glass window and door system movably installed in a window frame. The pair glass window and door system includes a pair glass structure including spacers and glasses attached to front and rear portions of the spacers such that the spacers are sealed by means of the glasses, a door frame for surrounding an outer peripheral portion of the pair glass structure, a blind driving unit fixed to an inner upper portion of the pair glass structure, and an auto blind accommodated in the pair glass structure while being suspended to an upper portion of an internal cavity of the pair glass structure, the auto blind being developed or shrunken by means of the blind driving unit. The blind driving unit includes a motor, a reduction gear box for adjusting driving force and an R.P.M of the motor, a coupler connecting a rotating shaft of the reduction gear box with a blind rotating shaft so as to transfer rotational force of the rotating shaft of the reduction gear box to the blind rotating shaft, adjustment wires connected to the blind rotating shaft and the blind in order to adjust an up/down movement and angular positions of the blind according to rotation of the blind rotating shaft, a counter gear formed with gear teeth and fixedly coupled to one of the rotating shaft of the reduction gear box, the blind rotating shaft and the coupler, a photo sensor aligned adjacent to the counter gear so as to detect an operation of the blind caused by the adjustment wires through counting an R.P.M of the blind shaft by detecting a rotational movement of the counter gear, and a controller including a signal receiving section for receiving remote-control signals and a CPU for controlling the operation of the blind by adjusting a driving direction of the motor and power supplied to the motor based on signals from a remote controller and the photo sensor.
