| abstract |
A card stacker includes a stack support that supports a stack of card substrates, a card lift mechanism, a card feed mechanism, and a retraction mechanism. The card lift mechanism is configured to support the card substrate in a lift position below the stack support, and drive the card substrate to a raised position, in which the card substrate is supported on the stack support at the bottom of the stack. The card feed mechanism includes a first transport roller having a feed position, in which the first transport roller engages a top surface of the card substrate in the lift position, and a retracted position when the card substrate is in the raised position, in which the first transport roller is on the bottom side of the stack support. The retraction mechanism is configured to move the first transport roller between the feed and retracted positions. |
