The invention provides a media treatment apparatus. When a media(5) approaches to a reference end(13), the end of the media(5) does not conflict with the side of a feed roller(8). In the media treatmeThe invention provides a media treatment apparatus. When a media(5) approaches to a reference end(13), the end of the media(5) does not conflict with the side of a feed roller(8). In the media treatment apparatus(1), the media(5) delivered by the feed rollers(8,10) in the delivery path(3) is delivered by side towards the reference end(13) by utilization of an alignment roller(14); a circular truncnt apparatus(1), the media(5) delivered by the feed rollers(8,10) in the delivery path(3) is delivered by side towards the reference end(13) by utilization of an alignment roller(14); a circular truncated cone shaped roller guider(16) capable of racing is arranged at the opposite side of the feed roller(8) in the reference end(13) direction, the roller guider and the feed roller (8) being coaxial;ated cone shaped roller guider(16) capable of racing is arranged at the opposite side of the feed roller(8) in the reference end(13) direction, the roller guider and the feed roller (8) being coaxial; consequently, when the media(5) is kept to the side by the alignment roller(14), the end of the media(5) does not conflict with the side of a feed roller(8).consequently, when the media(5) is kept to the side by the alignment roller(14), the end of the media(5) does not conflict with the side of a feed roller(8).
