Printer and ink cartridge attached thereto

In a printer of the present invention, an EEPROM that carries out sequential access and has a relatively small storage capacity is applied for storage elements mounted on both black and color ink cartridges, which are detachably attached to the printer. Pieces of information relating to each ink cartridge, for example, pieces of information on remaining quantities of respective inks in the ink cartridge, are stored in the storage element of the ink cartridge. A format of addressing adopted in the storage elements of the ink cartridges Is different from that adopted in an EEPROM incorporated in a printer main body of the printer. A control IC provided in the printer accordingly converts the storage format of addressing, before writing the information into the storage elements of the ink cartridges. In the printer, a RAM is mounted with the control IC on a carriage, and the pieces of information to be written Into the storage elements of the ink cartridges are temporarily registered in the RAM. The pieces of information are then written into the respective storage elements of the black and color ink cartridges, for example, at a timing of a powe-off operation. The signal lines and the memory used in the course of writing the information into the storage elements are identical with the signal lines, through which print data are transmitted to a print head mounted on the carriage of the printer, and the memory, in which the print data are stored. The arrangement of the present invention reduces the manufacturing cost of the ink cartridge and also enables size reduction of the whole printer.< / PTEXT>

Inkjet recording apparatus and method

An inkjet recording apparatus includes: a liquid ejection head which ejects an aqueous ultraviolet-curable ink toward a recording surface of a recording medium; a holding and drying unit including: a suction holding drum which conveys the recording medium while holding a back surface side of the recording medium by suction through suction holes formed in an outer circumferential surface of the drum; and a hot air flow drying device disposed to face the outer circumferential surface of the drum; a transfer conveyance device which is arranged at a downstream side of the holding and drying unit and conveys the recording medium while holding a leading end of the recording medium and curving the back surface side in a convex shape; and a fixing unit including an ultraviolet light irradiation device which is arranged at a downstream side of the transfer conveyance device and irradiates ultraviolet light onto the image.

RFID printer system, method of printing and sets of record members

A system and method for printing both record members having RFID transponders disposed thereon and record members not having RFID transponders disposed thereon. In one embodiment, a RFID printer receives data to be printed on a record member and determines if the data includes RFID data to be written to a RFID transponder embedded on a record member. If the received data includes RFID data, the RFID printer prints a RFID record member according to the received data. If the received data does not include RFID data, the RFID printer transmits the data to a non-RFID printer for printing. In another embodiment, a non-RFID printer receives data to be printed on a record member and determines if the data includes RFID data to be written to a RFID transponder embedded on a record member. If the received data does not include RFID data, the non-RFID printer prints a record member according to the received data. If the received data does include RFID data, the non-RFID printer transmits the data to a RFID printer for printing. At least one set of RFID record members in a RFID web is written to and printed with data. At least one set of non-RFID record members in a non-RFID web is printed with the same data. The set(s) of RFID record members are associated with the set(s) of non-RFID members by the same indicium which is printed on at least one RFID record member and in at least one non-RFID record member having related data. When there are plural sets of RFID record members, wherein the sets of RFID record members have different data, and there are plural sets of non-RFID record members, wherein the sets of non-RFID record members have different data, and the data of the sets of RFID record members and the sets of non-RFID record members have related data, differing indicia are printed on at least one record member of each set to associate the sets of RFID and non-RFID record members.

Thermal printing

A conventional thermal printer has had a structure in which a platen roller cannot be removed from a frame. Therefore, it has been necessary to insert a printing paper between a thermal head and the platen roller. Thus, it has been hard to load the printing paper. In order to solve the problem, there has been devised means for engaging the platen roller with the frame by the biasing force of the thermal head pressing the platen roller to forcibly lift up the platen roller, thereby removing the platen roller. However, there have been problems in that great operating force is required for the removal and the precision in a platen roller support position is low. A frame is provided with a slit (1c) having such a shape as to guide a bearing of a platen roller (2), and the bearing of a platen roller (2) is pushed against the slit by a lock arm using the biasing force of a pressure spring (8) for causing a thermal head (5) to come in press-contact with the platen roller (2). Consequently, the platen roller (2) is supported.
