Abstract
A coil binding apparatus includes a coil forming mechanism to form a helical coil in different diameters from a wire, a binding mechanism to bind a punched portion of a paper stack with the helical, and a coil introducing mechanism disposed between the coil forming mechanism and the binding mechanism to receive the helical coil drawn out of the coil forming mechanism and to introduce the helical coil to the binding mechanism. The coil introducing mechanism has a center axis shifting unit configured to shift a coil center axis position to a coil rotation axis position. The coil center axis position is a position of a center axis of the helical coil. The coil rotation axis position is a position of a rotation axis of the helical coil when the binding mechanism rotates the helical coil to insert the helical coil into the paper stack.
