binding machine including the feature of a flexible spring plate
connected to a second clamp member and defining a concave surface
facing a first clamp member. Independent claim 7 addresses the
feature of a flexible spring plate with a cross sectional shape

feature of plural flexible spring plates.

facing a perpendicular plate 13. As recognized by the examiner,
