  The paper feeding unit 2 feeds the printing medium P to n (n is an integer of 2 or more) printing units 4 by belt conveyance. In the paper supply unit 2, the printing medium P is stacked. When a printing medium input instruction is issued to the printing machine, the vacuum attracts the printing medium P at a set printing speed and inputs it onto the belt conveyance. Alternatively, using a kicker roll, the printing medium P is fed onto the belt conveyance.

  The first transport unit 3a belt-conveys the printing medium P fed from the paper feed unit 2 and supplies it to n (n is an integer of 2 or more) printing units 4. The 1st conveyance part 3a consists of two belts, and it conveys by driving the lower part of the to-be-printed medium P. As shown in FIG.

  The n (n is an integer of 2 or more) printing units 4 perform printing on the printing medium P that is belt-conveyed from the first conveyance unit 3a. The printing method of n (n is an integer of 2 or more) printing units 4 is not particularly limited, and is particularly limited to offset printing, gravure printing, intaglio printing, screen printing, flexographic printing, inkjet printing, and the like. There is no. However, when card printing is considered, offset printing is preferable, and waterless offset printing is more preferable. The offset printing includes an ink input unit for supplying ink, a plate surface portion on which a printing plate surface is mounted, and a fleshing portion for attaching the ink to a roller and transferring it to a printing medium P (not shown). For ink used for printing, basic four colors of cyan, magenta, yellow and black can be employed. Further, in order to print the forgery prevention technique on the printing medium P, it is preferable to print black with carbon black or the like that absorbs infrared rays. Furthermore, in order to print the anti-counterfeiting technology on the printing medium P, optical ink such as magnetic ink, conductive ink, thermochromic ink, ultraviolet light emitting ink, infrared transmitting ink, infrared absorbing ink, pearl pigment, Meric ink etc. are mentioned.
