|1. An automatic card-cutting apparatus provided with plural transfer rollers to transfer paper, plural slitter heads to cut the paper in a transferring direction, and a lateral cutter portion to cut the paper in a lateral direction at right angles with the transferring direction to conduct divisional cutting of the paper into plural cards comprising a construction in which:
each of the plural slitter heads is provided with a side head [ comprise a pair of side heads and a pair of middle heads, each side head being ] disposed as to be freely position-adjusted in the lateral direction to cut a. [ a ] side edge portion of the paper into belt shape , [ ;] and a middle head [ each middle head ] having elastic pushing members, an upper blade of disc and a pair of lower blades [ , ] each of which contacts each of the left and right side edge portions of the upper blade , [ ; wherein each of the pair of lower blades is ] disposed as to be freely position-adjusted [ and elastically pushed ] in the lateral direction by the elastic pushing members [ respectively toward the left and right side edge portions of the upper blade ] to cut a longitudinal middle waste portion of the paper into belt shape [ ,
the pair of lower blades are rotationally driven by a rotational force transmitting shaft, and the upper blade has a right angle edge portion attached to a short shaft freely supported by a casing of the middle head as to make the upper blade, to which the short shaft is attached, freely idle and rotate together with the pair of lower blades by frictional force of contact portion with the rotationally driven lower blades, the pair of lower blades rotationally driving the upper blade] .
