1. A device for folding a continuous paper having perforations, the device comprising:
a swing arm pivotable about an axis at one end of the swing arm to guide the continuous paper to be accordion-folded along
the perforations with equal widths as a result of a swinging operation of the swing arm, and
a table that receives the folded continuous paper fed via the swing arm,
wherein the swing arm includes a telescopic structure varying the length of the swing arm to at least two different lengths
in a swing,
wherein the swing arm comprises an arm main body, a sub-arm disposed on a free end of said arm main body, and a telescoping
operation motor which extends and retracts said sub-arm from the tip of said arm main body,
wherein said swing arm is pivoted about said axis by a swing operation motor disposed in said axis,
wherein said sub-arm has a pair of plate members that both project from the tip of said arm main body when the swing arm swings
to either side, and
wherein said sub-arm maintains a pre-determined distance between a lowest portion of said sub-arm and an upper surface of
said continuous paper placed on the table, thereby reducing a size of a part of the continuous paper which is subjected to
a wind-pressure.
