A hinge mechanism having first and second pivot shafts held by first and second hinge base members, respectively, which also connect to ends of a hinge arm member. First and second cams on the first and second hinge base members engage first and second control levers on the ends of the hinge arm members. First and second cam portions are provided by the opposed ends of the hinge arm member respectively and engage first and second pivotable check plates. First and second follower members are mounted on the first and second check plates respectively and contactable with the first and second cam portions respectively. First and second springs bias the first and second check plates in a direction to press the first and second follower members on the first and second cam portions respectively. A third spring biases a link member toward the first hinge base member.
