Abstract
Abstract A card feeding device for feeding a rectangular card along a card feeding direction that intersects a line across the width of the card at a right angle. The card feeding device includes a guide mechanism for leading guide portions provided at side edges of the card along the card feeding direction, a drive roller for elastically contacting a first side edge of the card, and a facing roller positioned opposite to the drive roller for freely and rotatably contacting a second side edge of the card opposite the first side edge of the card contacted by the drive roller. An axis of rotation of the drive roller is displaced, in a direction opposite to the card feeding direction, from an axis of rotation of the facing roller, such that the drive roller and the facing roller hold the card and feed the card directly in the card feeding direction.

Claim 1
Independent Claim
151 words
A card feeding device for feeding a rectangular card along a card feeding direction that intersects a line across the width of the card at a right angle, the card feeding device comprising: a guide mechanism for leading guide portions provided at side edges of the card along the card feeding direction; a drive roller for elastically contacting a first side edge of the card; and a facing roller positioned opposite to the drive roller for freely and rotatably contacting a second side edge of the card opposite the first side edge of the card contacted by the drive roller; wherein an axis of rotation of the drive roller is displaced, in a direction opposite to the card feeding direction, from an axis of rotation of the facing roller, such that the drive roller and the facing roller hold the card and feed the card directly in the card feeding direction.
Claim 2
Dependent Claim
151 words
A card feeding device for feeding a rectangular card along a card feeding direction that intersects a line across the width of the card at a right angle, the card feeding device comprising: a guide mechanism for leading guide portions provided at side edges of the card along the card feeding direction; a drive roller for elastically contacting a first side edge of the card; and a facing roller positioned opposite to the drive roller for freely and rotatably contacting a second side edge of the card opposite the first side edge of the card contacted by the drive roller; wherein an axis of rotation of the drive roller is displaced, in a direction opposite to the card feeding direction, from an axis of rotation of the facing roller, such that the drive roller and the facing roller hold the card and feed the card directly in the card feeding direction.
Claim 3
Dependent Claim
67 words
The card feeding device according to claim 1, wherein the guide mechanism includes a pair of guide channel members having guide channels formed therein for receiving the guide portions provided at side edges of the card, said guide channels being positioned opposite each other along a line intersecting the card feeding direction at a right angle so that the card is guided in the card feeding direction.
Claim 4
Dependent Claim
41 words
The card feeding device according to claim 2, wherein the drive roller is held biased at an operating position such that at least a portion of an external wall of the drive roller projects inward into one of the guide channels.
Claim 5
Dependent Claim
45 words
The card feeding device according to claim 1, wherein the axis of rotation of the drive roller is displaced in the direction opposite to the card feeding direction from the axis of rotation of the facing roller by a distance not greater than 1 mm.
Claim 6
Dependent Claim
34 words
The card feeding device according to claim 1, further comprising a guide roller contacting the second side edge of the card at a position forward of the facing roller in the card feeding direction.
Claim 7
Dependent Claim
31 words
The card feeding device according to claim 1, further comprising a detection switch coupled to the facing roller, said detection switch detecting insertion of the card into the card feeding device.
Claim 8
Dependent Claim
222 words
A card loading device for loading a card into a receptacle, said card loading device comprising: a card feeding device for feeding a rectangular card along a card feeding direction toward the receptacle, said card feeding direction intersecting a line across the width of the card at a right angle; and a card pushing mechanism for contacting a rear portion of the card fed by the card feeding device, and for advancing the card in the card feeding direction until a connector provided a front portion of the card is connected to a connector provided in the receptacle; wherein the card feeding device comprises: a guide mechanism for leading guide portions provided at side edges of the card along the card feeding direction; a drive roller for elastically contacting a first side edge of the card; and a facing roller positioned opposite to the drive roller for freely and rotatably contacting a second side edge of the card opposite the first side edge of the card contacted by the drive roller; wherein an axis of rotation of the drive roller is displaced, in a direction opposite to the card feeding direction, from an axis of rotation of the facing roller, such that the drive roller and the facing roller hold the card and feed the card directly in the card feeding direction.
Claim 9
Dependent Claim
222 words
A card loading device for loading a card into a receptacle, said card loading device comprising: a card feeding device for feeding a rectangular card along a card feeding direction toward the receptacle, said card feeding direction intersecting a line across the width of the card at a right angle; and a card pushing mechanism for contacting a rear portion of the card fed by the card feeding device, and for advancing the card in the card feeding direction until a connector provided a front portion of the card is connected to a connector provided in the receptacle; wherein the card feeding device comprises: a guide mechanism for leading guide portions provided at side edges of the card along the card feeding direction; a drive roller for elastically contacting a first side edge of the card; and a facing roller positioned opposite to the drive roller for freely and rotatably contacting a second side edge of the card opposite the first side edge of the card contacted by the drive roller; wherein an axis of rotation of the drive roller is displaced, in a direction opposite to the card feeding direction, from an axis of rotation of the facing roller, such that the drive roller and the facing roller hold the card and feed the card directly in the card feeding direction.
