Abstract

A card printing apparatus for sequentially printing a plurality of colors on a card has a card supply unit for supplying a card; a card conveyance path provided linearly from the card supply unit for conveying the card; a conveyance device provided on the card conveyance path for conveying the card; a printing unit provided on the card conveyance path; a card cleaning member disposed between the card supplying unit and the printing unit provided within the returning range of the card while printing the card conveyed in reverse; and a card cleaning member moving device for moving the card cleaning member to a retreated position separated from the card cleaning member and the card conveyance path, and an operating position. The card cleaning member is moved to the retreated position when the card is conveyed in reverse while printing.

Claims

1. A card printing apparatus for sequentially printing a plurality of colors on a card, comprising:

a card supply unit for supplying the card;

a card conveyance path provided linearly from the card supply unit to convey the card;

a conveyance device provided on the card conveyance path for conveying the card;

a printing unit provided on the card conveyance path, the printing unit printing a first color while conveying the card and printing a next color while conveying the card in a reverse direction after positioning the card;

a card cleaning member disposed between the card supply unit and the printing unit within a returning range of the card while printing the card conveyed in reverse, the card cleaning member contacting the card supplied from the card supply unit and cleaning the card;

a holder for holding the card cleaning member; and

a card cleaning member moving device having an actuator, the actuator moving the holder holding the card cleaning member between a retreated position spaced from the card conveyance path where the card cleaning member does not contact a surface of the card being conveyed, and an operating position where the card cleaning member contacts the surface of the card being conveyed by advancing into the card conveyance path,

wherein the card cleaning member is moved to the retreated position when the card is conveyed in reverse while printing

wherein the holder is detachably attached to the card printing apparatus,

the actuator comprises a solenoid, a plunger attached to the solenoid to project from or retract into the solenoid by an actuation of the solenoid, a lever member rotationally attached to the plunger at one end, and an engaging member engaging the other end of the lever member, the holder detachably engaging the engaging member, and

the holder and the engaging member include convex and concave portions engaging each other, respectively, so that the holder is attached to or detached from the engaging member by insertion.

2. A card printing apparatus according to claim 1, further comprising:

a card discharging member disposed under the card supply unit and discharging the card printed, and

a moving mechanism for moving a part of the conveyance device to form a discharging path to discharge the card from the card discharging member,

wherein the moving mechanism moves the conveyance device in between a level conveyance path to print and supply cards, and an oblique conveyance path to discharge a printed card.

3. A card printing apparatus according to claim 2, wherein the card cleaning member comprises a cleaning roller having an adhesiveness;

the conveyance device comprises a conveyance roller conveying the card; and

the conveyance roller and the cleaning roller convey the card by nipping the card in a condition that the conveyance roller is positioned in the level conveyance path, and the cleaning roller is positioned in the operating position.

4. A card printing apparatus according to claim 3, wherein said card cleaning member further comprises a cleaner contacting the cleaning roller only when the cleaning roller is in the operation position, to thereby remove dirt adhered to the cleaning roller, the cleaner being disposed away from the card conveyance path.

5. A card printing apparatus according to claim 1, wherein the card cleaning member is moved to the operating position when the card is supplied.

6. A card printing apparatus according to claim 1, wherein the actuator is positioned at a side of the card cleaning member relative to the card conveyance path.
