Abstract:
1. A medium cutting device for cutting a conveyed continuous medium to a predetermined length, comprising: a cutting unit including a cutting side rotator provided with a cut blade for cutting the continuous medium on an outer surface, and a receiving side rotator arranged to face the cutting side rotator; and an entanglement preventing unit including a pair of rotators arranged to face each other downstream of the cutting unit in a conveyance direction, wherein the entanglement preventing unit prevents the continuous medium cut by the cutting unit from being entangled with one of the cutting side rotator and the receiving side rotator; wherein a linear speed of an outermost perimeter of the rotators in the entanglement preventing unit is made to be faster than a conveyance speed of the continuous medium conveyed by the cutting unit; wherein a frictional member is provided on an outer surface of each of the rotators in the entanglement preventing unit; wherein the frictional member comprises a plurality of linear members extending in a diameter direction of each of the rotators; and wherein P≧t is satisfied, where an interval between adjacent linear members is P and a thickness of the continuous medium is t.
