PURPOSE: A triangular prism-shaped rotary advertising system is provided to display advertising images to 360 degrees and maximize an advertising effect by arranging six triangular prisms on each side and each vertex of a regular triangle and rotating the arranged triangular prisms. CONSTITUTION: A triangular prism-shaped rotary advertising system includes six triangular prisms(11a-11f), a plurality of top/bottom rotary discs, a driver(20), a supporter(15), and a motor(17). Advertising images are formed on each side of the six triangular prisms(11a-11f). The top/bottom rotary discs are used for supporting the triangular prisms. The top/bottom rotary discs and a main shaft(12) are rotated simultaneously. The driver(20) rotates the triangular prisms. The supporter(15) is installed under the driver in order to support the main shaft(12) and the driver. The motor(17) is installed under the supporter.
