PURPOSE: A sunbeam adjustment and advertisement change system using dual glass window film is provided to promote reduction of noise from outside, energy saving and excellent visual effects as well as to prevent the mechanism from being freezing and frost caused by difference between indoor and outdoor temperature. CONSTITUTION: A sunbeam adjustment and advertisement change system is available for repeating or stopping the vertical reciprocation in an inner space by connecting multi-changing advertising picture or phrase films sequentially. The sunbeam adjustment and advertisement change system adopts the dual air space glass window frame structure for flexible films depending on changes in indoor and outdoor temperatures caused by the sunlight of summer and the cold air of winter. A frame opening isolates all of dust and caulks in and out of two sheets of frames. When a free wheel gear bearing(1) is driven in one direction and a roller(3) is rotated, films are drawn or pulled through a film path. Rolling of the films is controlled as a tensile coil spring(7) supports or rubs each shaft(4,5) and a bearing holder(2) together with a washer(7). The sunbeam adjustment and advertisement change system is installed by driving of a deceleration clutch motor(M) or a motor(M) or by frequent or single operation. The system reduced outside noise, saves energy and increases indoor and outdoor visual effects by adopting the dual structure of frame. A direct ray of light introduced into a window is prevented from discoloring or changing in quality of indoor articles.
