In actual practice, an entire stack of cards is usually being placed into a card hopper of the card feeder, and via a feeding mechanism of the card feeder, one card at a time is outputted to the printing area.
- However, in the process of production, the cards in the entire stack of cards are not easily to be separate from each other due to static electricity or furry edges. In addition, according to usage requirements, the cards also have a variety of thickness specification. Therefore, the design of the card feeder has to consider the factors of the cards being difficult to be separated from each other and different in thicknesses, so as to ensure that the cards can be supplied normally.

first feed roller 136 a provides a constant driving force to the cards C, thesecond feed roller 136 b provides a compensation driving force to the cards C, and a sum of the driving forces is greater than a separation force provided by thefriction element 140, so as to ensure that the cards C can be outputted, smoothly. In addition, by driving thesupport 131 to rotate along the axis A so as to enable thesecond feed roller 136 b to push the cards C toward thefriction element 140, when supplying the cards C of different thicknesses, thesecond feed roller 136 b can provide an automatic compensation of normal force in relative to thefriction element 140 to the cards C. - Referring to
FIG. 2 again, in the present embodiment, only onegear 133 a is pivoted on thebase 110. However, in other non-illustrated embodiments, a plurality ofgears 133 a that are sequentially and mutually engaged may also be pivoted on thebase 110 for transmitting the torque generated by thepower source 135 a to thegears 133 a that are coupled to thefirst feed roller 136 a and thesecond feed roller 136 b through the sequentially and mutually engaged gears 133 a that are pivoted on thebase 110, so as to drive thefirst feed roller 136 a and thesecond feed roller 136 b into rotation. -
FIG. 5 is a partial cross-sectional view illustrating a card feeder according to still another embodiment of the invention. Referring toFIG. 5 , different from the embodiment illustrated byFIG. 2 , acard feeder 100 b of the embodiment illustrated byFIG. 5 has an elastomer 150 (such as a spring), and theelastomer 150 is disposed between the base 110 and the conveyingunit 130, so that the conveyingunit 130 applies pressure on the cards C towards thefriction element 140. Specifically, theelastomer 150 can push thesupports 131 of the conveyingunit 130 in relative to thebase 110, so that thesecond feed roller 136 b pivoted on thesupports 131 can apply pressure to the cards c toward thefriction element 140. Under this circumstance, the configuration of theelastomer 137 in the embodiment illustrated byFIG. 2 andFIG. 3A may be replace. - In summary, the invention uses the conveying unit to push the cards into motion, and uses the friction element to provide the friction force to the cards so as to separate the cards. In addition, the invention may uses the transmission mechanism, the first feed roller and the second feed roller to convert the torque generated by a single power source into the driving force of the cards. Moreover, according to the difference in the thickness of the cards, the invention may further provide the automatic compensation of the normal force to the cards via the support, the transmission mechanism, the second feed roller, the elastomer, and the same power source, so as to ensure that the cards of different thicknesses can all be separated by the friction element successfully.
- It will be apparent to those skills in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.

a friction element disposed on the base and located in a path passed by the card, and being capable of providing friction force to the cards so as to separate the cards.
2. The card feeder as recited in claim 1 , wherein the conveying unit comprises:
a support pivoted, along an axis, to the base;
a transmission mechanism disposed on the base and the support;
a power module coupled to the transmission mechanism so as to drive the transmission mechanism;
a first feed roller pivoted on the base, and coupled to the power module through the transmission mechanism so as to be driven by the power module into rotation, so that the cards move toward the exit; and
a second feed roller pivoted on the support, and coupled to the power module through the transmission mechanism so as to be driven by the power module into rotation, so that the cards move toward the exit, and the exit is located between the second feed roller and the friction element.
3. The card feeder as recited in claim 2 , wherein the transmission mechanism includes a plurality of gears, the gears are sequentially and mutually engaged, and the gears comprises at least one gear pivoted on the base and at least one gear pivoted on the support.
4. The card feeder as recited in claim 3 further comprising:
a rotating shaft axially disposed, along the axis, to the base, the support and the gear rotating along the axis, and fixedly connected to the gear rotating along the axis.
5. The card feeder as recited in claim 3 , wherein the conveying unit further comprises:
a driving shaft axially disposed on the base and coupled to the power module and the transmission mechanism.
6. The card feeder as recited in claim 3 , wherein the conveying unit further comprises:
an elastomer disposed between the support and the gear pivoted on the support so as to provide the friction force, so that the gear rotating along the axis is able to drive the support to rotate along the axis, thereby enabling the second feed roller to apply pressure on the cards towards the friction element.
7. The card feeder as recited in claim 2 , wherein the power module further comprises:
a power source;
a deceleration mechanism coupled between the power source and the transmission mechanism, wherein torque generated by the power source is transmitted, sequentially through the deceleration mechanism and the driving shaft, to the transmission mechanism.
8. The card feeder as recited in claim 3 further comprising:
an elastomer disposed between the base and the conveying unit, so as to enable the conveying unit to apply pressure on the cards towards the friction element.
