Claim of US Patent No. 9,233,785

1. A lid opening/closing mechanism for switching a lid between a closed position closing an opening portion of a base body,
and an open position opening the opening portion, comprising:
an arm allowing a tip side thereof to turn to a front of the base body as a support point with a base end side thereof pivotally
supported at the base body by a first axis support portion, and connected to the lid turnably by a second axis support portion,
and

a control member provided to be slidably placed in a guide portion provided in the base body, and turnably connected at a
tip side to the lid through a third axis support portion,

wherein the lid is turned in an opening direction or a closing direction in association with a turn of the arm,
in an opening/closing process of the lid, the second axis support portion moves the lid to the front of the base body by the
turn of the arm around the first axis support portion, and

the arm is arranged to turn the lid toward the closing direction when the lid is disposed at a position between the closed
position and a switching mid-course position in which the first, second and third axis support portions are relatively lined
up approximately in a straight line when viewed parallel to hinging axes of the first axis support portion, second axis support
portion and third axis support portion, and to turn the lid toward the opening direction when the lid is disposed at a position
between the open position and the switching mid-course position.
