A cover opening and closing device switches a cover body to rotate between a closed position and an open position. The cover opening and closing device includes a single operation button for switching the cover body between the closed position and the open position, a forcing device for forcing the cover body at least toward the closed position from a near closed position when the cover body is closed, and a switching device for releasing the cover body in the open position and allowing the cover body to rotate toward the closed position when the operation button is pushed.
