<p>A revolving type bulletin apparatus providing information is disclosed. The revolving type bulletin apparatus providing information comprises a rotation plate that is installed between a lower cover and an upper cover and rotated by a power transfer part. A photovoltaic part is installed on the upper surface of the upper cover. The photovoltaic part is obliquely installed on the upper surface of the light collection panel of the photovoltaic device. A lower surface comprises an installation frame bearing-combined with the upper cover, a first internal gear formed on the lower inner surface of the installation frame, and a power transfer shaft having a second internal gear engaging with the first internal gear and vertically coupled to a part of the upper cover through a shaft. The power transfer part comprises a main shaft coupled to the upper cover and the lower cover through the shaft, a driving motor transferring a rotation force to the main body and installed to the lower cover, a first power transfer gear formed on one surface of a guide protrusion and an operation protrusion and coupled to the upper part of the main shaft through the shaft, and a second power transfer gear comprising rotation protrusions rotating to guide the guide protrusion of the first power transfer gear and coupled to the lower part of the power transfer shaft, and an operation groove partly rotating at an angle due to the operation protrusion and prepared between the rotation protrusions.</p> |
