Abstract
An upper frame opening and closing mechanism, including an upper frame pivotally attached to a main body, which may include an image forming device, so as to open and close on a hinge, which receives a moment in an opening direction due to gravity when the upper frame is opened at an angle exceeding an inversion angle to expose the image forming device, an arm member, a rail member to guide a leading edge of the arm member along with opening and closing of the upper frame, a biasing member to bias the upper frame in the opening direction, and a cushion member to be pressed by the leading edge of the arm member so as to cushion the opening of the upper frame when the upper frame is opened at a maximum opening angle relative to the main body.
