Patent ID: 8382102

Claim:
A transportation alignment device having a transportation means that conveys a medium, and an alignment member that can move to a forward position intervening in a transportation path of the medium and a retracted position retracted from the transportation path, the transportation alignment device causing a leading end of the medium to contact the alignment member, thereby aligning the medium, said alignment device comprising: a plurality of optical media detection sensors arranged across a width of the transportation path on an upstream side of the alignment member, each of said plurality of optical media detection sensors detecting a leading end part of the medium touching the alignment member; and a control means that, when the medium is conveyed a specific amount sufficient to contact the alignment member and align the medium and all of the media detection sensors do not detect the medium, determines the medium is a medium having an edge part with higher transmittance than a part other than the edge part, retracts the alignment member from the transportation path, and conveys the medium to a downstream side of the transportation path.
