Patent ID: 8351822

Claim:
A cover unit comprising: a cover defining a first end supported on a device case and freely rotatable thereon about a first axis of rotation, the cover being movable between a closed position, in which the cover is adjacent the device case, and an open position, in which a second end of the cover is separated from the device case; a rotation transfer member that is disposed at the second end of the cover, and extends parallel to the first axis of rotation across a width of the cover; an operating part disposed at a first end of the rotation transfer member; a first pressure part disposed at the first end of the rotation transfer member; a second pressure part disposed at a second end of the rotation transfer member; and first and second pressure-bearing parts that are disposed on the device case and are adjacent the first and second pressure parts, respectively, when the cover is in the closed position; wherein the first and second pressure parts are supported freely rotatably on a second axis of rotation parallel to the first axis of rotation, and wherein the operating part and the pressure parts are operably connected, and wherein the operating part, the pressure parts, and the pressure-bearing parts are relatively configured and located such that the operating part is rotatable between: a first position, at which neither of the pressure parts contacts a corresponding one of the pressure-bearing parts, and a second position, at which the second pressure part contacts the second pressure-bearing part and the first pressure part does not contact the first pressure-bearing part.
