1 is a boss, 12 is a blade, 80 is a pair of shafts provided in parallel with each other at an interval above and below the transport path 3 in a direction perpendicular to the transport direction of the medium 1 in the transport path 3, 8 is a pair of shafts 80 A plurality of pairs of feed rollers are fixed at a predetermined interval to the conveyance path 3 and are formed of an elastic resin material that respectively protrudes into the conveyance path 3 to nip and convey the medium 1; It is provided coaxially with the feed roller 8, and is made of a flexible and elastic material.
This is an impeller in which the diameter of the boss 11 is set larger than the outer diameter of the feed roller 8, and a plurality of blades 12 are formed radially around the outer periphery.

Therefore, the leading end of the medium 1 being conveyed through the conveyance path 3 is guided by the plurality of blades 12 of the rotating impeller 10 so as to be held between the plurality of pairs of feed rollers 8 and conveyed. .

[Effect]

When the medium 1 conveyed through the conveyance path 3 is flapped by the impeller 10, since the outer periphery of the feed roller is inside the diameter of the boss 11, the leading edge of the medium 1 does not collide with the outer periphery of the feed roller 8. It is guided and conveyed by the plurality of blades 12 of the impeller 10 so as to be held between a pair of feed rollers 8 .

Therefore, even if the medium 1 is folded or curled, it is normally conveyed by the blades 12 of the impeller 10, so that jamming can be prevented.
