Card attitude correction device and card printing apparatus including the same

A card attitude correction device comprising:

• a first roller set configured to convey a card in a turnable manner while pinching a central region of the card in a width direction perpendicular to a conveyance direction;
• a second roller set disposed separately from the first roller set in one direction of the conveyance direction, and including an intermittent roller configured to generate, during one rotation, a conveyance enabled time of contacting the card and conveying the card and a conveyance disabled time of not contacting the card and not conveying the card;
• a third roller set disposed separately from the second roller set in the one direction, and configured to convey the card in an unturnable manner;
• a reference guide wall movable in a direction perpendicular to the conveyance direction, and configured to receive abutment of a first end portion of the card in the width direction and to arrange a position of the card in the width direction at a reference position;
• an urging guide wall configured to urge a second end portion of the card, the second end portion being opposite to the first end portion, toward the reference guide wall by a first urging force;
• and
• a support wall configured to regulate a movement of the reference guide wall toward the urging guide wall at a position serving as the reference position,
• wherein the reference guide wall is urged by a second urging force larger than the first urging force toward the urging guide wall and made movable in a direction perpendicular to the conveyance direction and separating from the urging guide wall by a force to resist the second urging force,
• wherein, during the conveyance disabled time when the card is located at a position at which it is possible to convey the card by the second roller set, the first roller set and the third roller set are incapable of conveying the card, and the urging guide wall corrects an attitude of the card and a position of the card in the width direction by urging the card by the first urging force to allow the card to abut against the reference guide wall positionally regulated by the support wall,
• and wherein, when the card is conveyed toward the reference guide wall at a position at which the first end portion shifts to an opposite side to the urging guide wall with respect to the reference position, the reference guide wall maintains the position serving as the reference position regulated by the support wall and conveys the card while turning the card in a case in which the card is conveyed by the first roller set, and the reference guide wall is retreated in a direction separating from the urging guide wall and conveys the card without turning the card in a case in which the card is conveyed by the third roller set.
