Patent attributes
An image scanner and image scanning method to reliably image scanned media in an image scanning apparatus with consistent quality. The image scanning apparatus may be included within a printer 10 for printing to the medium. The image scanning apparatus comprises a transportation mechanism for transporting a card C along a transportation path 41 from an insertion opening 41 and an image sensor 44 to image the card on the transportation path 41. Guide walls 54 guide the card C into alignment with the transportation path 41. The transportation mechanism conveys the card C in a forward direction toward the image sensor 44 to a specified indexing position, and then in reverse toward the insertion opening 41a. The image sensor 44 images the card C as the card C is transported in reverse from the indexing position. The card C is then discharged from the card insertion opening 41a.
