Card-flipping device for use in card printers
First Claim
1. A method comprising:
- providing card carrier unit having a cam arm and at least one flip guide for holding a card;
moving the card carrier unit from a starting position along a stationary guide structure in a first direction toward a first flip stop member in an extended position and a second flip stop member in an retracted position, wherein in the extended position the first flip stop member extends toward a cam arm channel for engagement with the cam arm and in the retracted position the second flip stop member extends away from the cam arm channel for avoidance with the cam arm;
exerting a reaction force on the cam arm by the first flip stop member in the extended position so that the cam arm rotates about an axis in a first direction, thereby causing the at least one flip guide to rotate; and
moving the first flip stop member from the extended position to a retracted position such that the first flip stop member extends away from the cam arm channel for avoidance with the cam arm and moving the second flip stop member from the retracted position to an extended position such that the second flip stop member extends toward the cam arm channel for engagement with the cam arm.

Abstract
A card-flipping device for a card printing apparatus is provided. The card-flipping device comprises a card-carrier unit for transporting the card in a vertical direction, a motor drive means for moving the unit in the vertical direction, and an actuator assembly including a rotatable cam arm for flipping the card over. The card-flipping device is particularly suitable for use in thermal dye printers that print images on card substrates such as driver'"'"'s licenses, employee badges, student cards, and the like. After one surface of the card has been printed, the card is conveyed to the card-flipping device, where the card is flipped over so that the reverse, unprinted side of the card can be printed thereon.

9. A method comprising:
-
transporting a card toward a printhead; printing at least one image onto a first surface of the card; transporting the card toward a card-flipping assembly; securing the card to a card carrier unit of the card-flipping assembly, wherein the card carrier unit includes a cam arm and at least one flip guide for holding a card; moving the card carrier unit along a stationary guide structure of the card-flipping assembly in a first direction toward a first flip stop member in an extended position and a second flip stop member in an retracted position, wherein in the extended position the first flip stop member extends toward a cam arm channel for engagement with the cam arm and in the retracted position the second flip stop member extends away from the cam arm channel for avoidance with the cam arm; exerting a reaction force on the cam arm by the first flip stop member in the extended position so that the cam arm rotates about an axis in a first direction, thereby causing the at least one flip guide and the card to rotate; moving the card carrier unit along the stationary guide structure in a second direction toward a flip stop actuator lever; engaging the flip stop actuator lever with the cam arm, thereby causing the first flip stop member to move to a retracted position and the second flip stop member to move to an extended position; moving the card toward the printhead; and printing at least one image onto a second surface of the card, wherein the second surface is opposite the first surface. - View Dependent Claims (10, 11)

12. A method for reorienting media used by a printer, comprising:
-
providing a media flipping unit comprising; a frame comprising at least one guide rail extending relative to a defined media path of a printer; a carrier unit slidably coupled to said guide rail for transporting the media in a first direction and in an opposite direction along said guide rail;
wherein the carrier unit includes at least one rotatable flip guide for holding the media; andat least one flip stop member adjacent said guide rail; inserting media into the rotatable flip guide of the carrier unit; sliding the carrier unit along the guide rail; causing contact between an arm connected to the rotatable flip guide and the flip stop member such that the rotatable flip guide rotates thereby reorienting the media located in the carrier unit;
wherein the flip stop member is locatable in both extended and retracted positions relative to the arm, and wherein in the extended position the flip stop member is positioned to interact with the carrier unit as the arm slides along the guide rail and in the retracted position the flip stop member is positioned to avoid the arm. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
