Abstract

A card transport device transports one or more cards while reducing failures of its feed unit in feeding the cards. A card transport device includes a support surface that supports one or more cards thereon, a feed unit facing the support surface for feeding the one or more chards, a separator located downstream from the feed unit in a transport direction, a slope connected to a downstream support end of the support surface in the transport direction and extending obliquely upward downstream in the transport direction toward the separator, and a restrictor located on the support surface. The restrictor restricts a position of an upstream end of a particular card directly supported on the support surface, out of the one or more cards, thereby positioning a downstream end of the particular card to be downstream from the feed unit in the transport direction.

Claims

1. A card transport device, comprising:

a support surface configured to support one or more cards thereon;

a feed unit facing the support surface, and configured to feed the one or more cards supported on the support surface downstream in a transport direction along a transport path;

a separator located downstream from the feed unit in the transport direction, and configured to transport the cards fed by the feed unit downstream in the transport direction while separating the cards from one another;

a slope connected to a downstream support end of the support surface in the transport direction and extending obliquely upward downstream in the transport direction toward the separator; and

a restrictor located on the support surface, and configured to restrict a position of an upstream end in the transport direction of a particular card directly supported on the support surface, out of the one or more cards, thereby positioning a downstream end of the particular card to be downstream from the feed unit in the transport direction.

2. The card transport device according to claim 1, wherein the restrictor is spaced upstream in the transport direction from the downstream support end of the support surface by a distance which is substantially equal to a card length standardized by ISO/IEC 7810 ID-1.

3. The card transport device according to claim 1, wherein:

the support surface has a recess conforming to an outline of each of the one or more cards, and

the restrictor includes a first inner wall included in inner walls defining the recess, and the first inner wall is located upstream from the other inner walls in the transport direction and extends in a width direction perpendicular to the transport direction.

4. The card transport device according to claim 3, wherein the inner walls defining the recess include a second inner wall defining a bottom of the recess, and the second inner wall extends obliquely downward and downstream in the transport direction.

5. The card transport device according to claim 3, further comprising a friction member located on a second inner wall included in the inner walls and defining a bottom of the recess, the friction member being adjacent to and downstream from the restrictor in the transport direction.

6. The card transport device according to claim 3, wherein the inner walls defining the recess include a third inner wall located downstream from the other inner walls in the transport direction, and the third inner wall extends in the width direction and is flush with the slope.

7. The card transport device according to claim 1, wherein the restrictor includes a rib protruding from the support surface.

8. The card transport device according to claim 7, wherein the restrictor protrudes from the support surface by a protruding length which increases from upstream to downstream in the transport direction, a protruding end of the restrictor extending obliquely relative to the support surface.

9. The card transport device according to claim 8, wherein the protruding length is greater than a card thickness standardized by ISO/IEC 7810 and smaller than twice the standardized card thickness.

10. The card transport device according to claim 7, further comprising a friction member located on the support surface, the friction member being adjacent to and downstream from the restrictor in the transport direction.

11. The card transport device according to claim 1, further comprising a stopper movable between a first position at which the stopper intersects at least one of the support surface and the slope to restrict downstream ends in the transport direction of the one or more cards supported on the support surface, and a second position at which the stopper is withdrawn from the at least one of the support surface and the slope to allow transportation of the one or more cards.

12. The card transport device according to claim 11, wherein:

the feed unit includes a feed roller configured to rotate about a first axis extending in a width direction perpendicular to the transport direction,

the separator includes a separation roller configured to rotate about a second axis parallel to the first axis,

the card transport device further includes a holder supported to be swingable about the second axis and holding the feed roller rotatably about the first axis, and

the stopper has an upper end configured to contact and move the holder away from the support surface in response to the stopper moving from the second position to the first position.

13. The card transport device according to claim 1, wherein the restrictor includes:

a first restricting member configured to restrict a short side at the upstream end of the particular card when the particular card is directly supported on the support surface with a long side thereof extending parallel to the transport direction, and

a second restricting member configured to restrict a long side at the upstream end of the particular card when the particular card is directly supported on the support surface with a short side thereof extending parallel to the transport direction.

14. The card transport device according to claim 1, further comprising a reader located downstream from the separator in the transport direction, and configured to read an image of the one or more cards transported along the transport path.

15. The card transport device according to claim 1, wherein the restrictor is immovable relative to the support surface and has a receiving surface configured to receive the upstream end of the particular card.

16. The card transport device according to claim 15, wherein the receiving surface of the restrictor extends by a predetermined length in the direction perpendicular to the transport direction and away from the support surface, the predetermined length being greater than a card thickness standardized by ISO/IEC7810 and smaller than twice the standardized card thickness.

17. The card transport device according to claim 1, wherein the support surface extends substantially horizontally.

18. The card transport device according to claim 1, wherein the one or more cards supported on the support surface are made of plastic.
