Abstract: Provided is a secure payment device. The secure payment device includes: a payment terminal on which a pin-pad including a keypad module is mounted and which is capable of communicating with a mobile terminal via a short-range communication; a mobile terminal accommodation unit coupled to one surface of the payment terminal to detachably couple the mobile terminal to the payment terminal; and a mounting unit screw-fastened to one surface of the payment terminal and including at least one fixing protrusion configured to slide into and be fixed at a fixing groove formed on one side surface of the mobile terminal accommodation unit, wherein the payment terminal includes at least one flexible protrusion configured to slide into and be fixed at a fixing groove formed on the other side surface of the mobile terminal accommodation unit.

Abstract: A pin-pad and pin-pad security method are provided. The pin-pad includes: a keypad module including a plurality of buttons; a main board comprising an encryption circuit configured to encrypt a key signal input from the keypad module; a first flexible circuit board to protect an upper portion of the main board; a second flexible circuit board to surround a side surface of the main board; a double cover to block access to a circuit in the main board; and an information blocking circuit unit configured to erase information stored therein to block leakage of the information when disconnection or a short-circuit of an electric circuit is detected from at least one of the main board and the first and second flexible circuit boards. When the pin-pad is disassembled or cut, information stored in an internal memory is erased to block leakage of the information remaining in the internal memory.

Abstract: The present invention relates to an ink cartridge for an inkjet printer, the ink cartridge comprising a head chip of a print head to be surface-mounted on an FPCB by means of BGA so as to have each contact terminal, which is formed on the FPCB and the head chip, to be formed over a relatively wide area and therefore not require a high level of integration technology. Therefore, the ink cartridge enables easy manufacturing of the FPCB and the head chip and lowering of manufacturing cost. Also, since relatively low precision needs to be maintained during the mounting of the head chip on the FPCB such that each contact terminal comes into contact, the ink cartridge enables more convenient and faster manufacturing of the print head.

Abstract: The present invention relates to an array-type ink cartridge. The present array-type ink cartridge comprises: a plurality of ink cartridge modules which each have a pair of heads arranged so as to cross each other in the longitudinal direction so that the print width expands; and a fixing plate for fixing the plurality of ink cartridge modules and aligning the fixing position so that the plurality of ink cartridge modules are in an array configuration in the longitudinal direction of the ink cartridge modules or the width direction of the ink cartridges. The array-type ink cartridge according to embodiments of the present invention can embody various colors and print widths of various sizes by using a plurality of ink cartridge modules, and can optionally expand the number of ink cartridge modules used according to the characteristics of a printing device.

Abstract: The present invention relates to an ink cartridge for an inkjet printer, the ink cartridge having a separate refilling port formed on the upper surface of a main body housing in which ink is stored and having mounted a port cover for opening and closing the refilling port, thereby enabling convenient refilling of ink through the refilling port by an individual user even without using a separate working tool or a specialized company for refilling ink. In addition, by having formed a display window for observing, with the naked eye from the outside, the amount of ink being refilled, the ink cartridge enables the user to easily perceive time for refilling ink. Also, by preventing the ink from being refilled too much or too little when the ink is being refilled, the ink cartridge enables refilling of an appropriate amount of the ink.

Abstract: The present invention relates to an ink cartridge. The ink cartridge comprises: a space for storing ink; an ink cartridge module having a pair of heads arranged in an offset manner such that a print width is extended; and a flexible printed circuit board connected to the ink cartridge module on a circuit configuration, wherein the ink cartridge module has a cross sectional shape in which two rectangular shapes having long sides and short sides respectively come in close contact with each other such that the long sides of the two rectangular shapes overlap in part, and thus can configure an array in the direction of either the long side or the short side. The ink cartridge according to the present invention can implement various sizes of print widths and various colors by arranging one or more ink cartridge modules adjacent to each other.

Abstract: An ink cartridge for an inkjet printer is provided, in which since contact terminals formed on a flexible printed circuit board (FPCB) and a head chip of a print head are formed on a large area by surface-mounting the head chip on the FPCB in a ball grid array (B GA) manner, a high level of integration technology is not required, hence the FPCB and the head chip are easily manufactured and manufacturing costs are decreased, and since a low level of precision needs to be maintained while mounting the head chip on the FPCB such that the contact terminals contact each other, the print head is conveniently and quickly manufactured. Also, since a high level of precise manufacturing technology is not required by disposing the contact terminal formed on the FPCB to have optimum space efficiency, the ink cartridge is easily manufactured and the head chip and the FPCB are easily connected to each other.
