Abstract: In a server; a ticket allotting unit generates, in response to a first request from a first user, first-type image code and stores the first-type information in a management database (DB) in a manner corresponding to a second user. Moreover, in response to a second request from the first user, generates second-type image code which is different from the first-type image code and stores the second-type image code in the management DB in a manner corresponding to a third user. Then, for example, a QR returning unit invalidates the first-type information stored in the management DB and validates the second-type information stored in the management DB. Then, a QR displaying unit sends the second-type image code to the third user.

Abstract: A thermal head avoids a drop in print quality caused by adhesion of printing chaff. A thermal head 39 that presses against thermal paper that moves from one side to the other side and prints by melting dye contained in the thermal paper has a glazed layer 150 that is formed in an area on one part of a ceramic substrate 43 and stores in-flowing heat, and a heating resistor 140 that is located offset to one side from the center of the glazed layer 150, selectively heats the thermal paper S pressed in contact therewith, and melts a dye material contained in the thermal paper. A smooth surface P against which the thermal paper S heated by the heating resistor 140 slides is formed to the other side of the glazed layer 150 from the heating resistor 140.

Abstract: A head substrate for mounting a driver IC that selectively drives a plurality of driving elements is provided. An input signal wiring pattern electrically connects external connection terminals with the pads in a first pad array and a second pad array. The input signal wiring pattern includes a clock signal line for supplying the clock signal to the driver IC and a logic power line for supplying the logic power to the driver IC. A part of the clock signal line and a part of the logic power line are disposed between the first pad array and the second pad array.

Abstract: A printer avoids scratching or damaging the platen and print defects caused by adhesive. The printer 1 prints to thermal paper S that has an adhesive area 150 formed on one side with the edges of the paper adhesive-free, and color layers formed on the other side of the paper. The thermal paper S is wound sequentially into a roll so that the other side is on the outside without applying a liner protecting the adhesive area 150 on the one side. The printer 1 has a platen 18, a heating element unit 43, and a guide incline 45. The platen 18 is disposed to a main cover, rotates in the thermal paper S transportation direction, and applies pressure to the thermal paper S from the one side. The heating element unit 43 selectively heats the other side of the paper.

Abstract: A multifeed detection apparatus and method for use in a check processing terminal including a paper supply unit for individually feeding a plurality of checks from the paper supply unit along a check transportation path in a given direction; a MICR head having a non-movable contact surface on one side of the check transportation path; a pressure member disposed on another side of the check transportation path opposite the non-movable contact surface for pressing one or more transported checks between the pressure member and the MICR head; and a displacement detection sensor for detecting physical displacement of the pressure member from the non-movable contact surface to indicate check thickness.

Abstract: A multifeed detection apparatus and method for use in a check processing terminal including a paper supply unit for individually feeding a plurality of checks; a check transportation path for conveying each check fed from said paper supply unit in a given direction along said path; a reading unit disposed on one side of the transportation path and having a rigid stationary surface and an image scanning sensor such as an MICR head for reading magnetic ink characters printed on the check with said check multifeed detection apparatus comprising: a pressure member disposed on another side of the check transportation path opposite to and in alignment with said rigid stationary surface for pressing one or more transported checks passing between the pressure member and the rigid surface up against said rigid stationary surface; and a displacement detection sensor for detecting the displacement of the pressure member by the transported check(s); a wherein the displacement detection sensor detects multifeeding based o

Abstract: A printer in which a cover to the roll paper holder in which roll paper is held can be easily opened even when such problems as a roll paper jam occur. Opening and closing a cover (30) to the roll paper loading mechanism (2) of the printer is detected by a photointerrupter (288) detecting whether the locking lever (280) is in a locked or unlocked position. When the lock is unlocked, an cover unlocked signal is asserted to the drive control unit (39). The drive control unit (39) then drives a solenoid (62B) to switch the drive motor (61) torque transfer path from the roll paper gear train to the slip form gear train. This disengages a first gear (71) on the printer and an engaging paper.

Abstract: In a printer which can print both a paper roll and cut paper, when cut paper is printed, a gap between the cut paper and a platen can be keep fixed. In an ink-jet printer 1 wherein a printing position for a paper roll 5 is formed in a part of a printing position 11 for cut paper 5, the surface of a platen for a paper roll 16 defining the printing position for the paper roll 5 is backed at least by a dimension G equivalent to the thickness of the paper roll from the surface of a platen for cut paper 13 defining the printing position for the cut paper 4. When cut paper is printed, a gap between a part of cut paper carried with the part overlapped on a paper roll and the platen is equal to a gap between the other part of the cut paper and the platen. Therefore, the deterioration caused by the variation of the gap of the quality of printing on cut paper can be solved.
