  • Patent number: 10354698
    Abstract: A rotation cover opening/closing mechanism includes a transparent plate-shaped cover, a shaft body, and a turning mechanism. The cover closes an opening portion formed in a part of an upper surface of device body. One end of the shaft body is perpendicularly fixed to the cover, and at least a part of the shaft body at the other end of the shaft body is inserted into the device body. The turning mechanism rotatably supports the shaft body inside the device body to allow turning of the cover around the shaft body in a plane parallel with the upper surface of the device body. The turning mechanism includes a limitation portion that limits a rotation angle of the shaft body to a fixed range such that the cover turns between a cover closing position where the cover closes the opening portion, and a cover opening position where the cover opens the opening portion.
