摘要:
A plurality of small loop antenna cells (61,62 and 63) are magnetically coupled to an antenna coil of a non-contact type data carrier. In the plurality of small loop antenna cells, the directions of the magnetic moments of the signals transmitted to the non-contact type data carrier are opposite to each other, the sum of the magnetic moments generated from all the small loop antenna cells (61 to 63) is zero and a conductor forming a short ring pattern 67 is provided collectively for the plurality of small loop antenna cells. Thus, imbalance caused between the small loop antenna cells (61 to 63) can be compensated for by the short ring pattern (67).

A plurality of terminals (210-270) are provided on a circuit board (200) of a structural body (100A,100B,100Aa,100Ab, 100Ac,100Ad), and a plurality of lines (L1,L2) are formed by contact portions (210c-270c) of the plurality of terminals (210-270). In a first line (L1) among the plurality of lines, contact portions of two terminals (210,250) for detecting attachment are arranged, and a contact portion (220c) of a power supply terminal (220) is arranged therebetween. The first line (L1) is located at a leading side when the structural body is moved in a predetermined direction and is mounted on a recording material-consumption device (1000) or the first line (L1) is the line closest to an opening of a recording material delivery member (110).

A circuit board (10) mounted on a marking material receptacle and having a storage device for storing data relating to a marking material for print, said circuit board (10) comprising a plurality of terminals (21-27) arranged on said circuit board (10) in a single direction and connected to the storage device, wherein two of said plurality of terminals (21-27) arranged at two edges of the circuit board (10) are ground terminals (24, 27) used for determining if the marking material receptacle has been installed correctly, wherein one of said ground terminals (24, 27) receives ground potential from a printer when the marking material receptacle is installed on the printer, and another of said ground terminals (24, 27) is connected to the one of said ground terminals (24, 27) on the circuit board (10) and to be connected to a cartridge out detecting pin of the printer when the marking material receptacle is installed on the printer.
摘要:
A circuit board (10; 200) for a marking material receptacle (40, 48), comprising a storage device (30) for storing data relating to a marking material for print, a plurality of terminals (21-27; 201-207) arranged on said circuit board (10; 200), said terminals comprising a power supply terminal (22; 202) and being arranged in a plurality of rows, characterized by two ground terminals (24, 27; 204, 207) arranged for allowing a printing device (100) to determine if said marking material receptacle has been installed correctly, where said ground terminals (24, 27; 204, 207) are located at the outermost ends of a row that is different than the row that contains said power supply terminal (22; 202), and where said ground terminals (24, 27; 202, 204) are not the terminals in closest proximity to said power supply terminal (22; 202).
摘要:
An information communicating member (400) is adapted to be disposed on a liquid container (200,201) for supplying a liquid to a liquid ejecting head (1) of a liquid ejection apparatus. The information communicating member (400) includes: an information storing portion (410) storing therein liquid information with regard to the liquid contained in the liquid container; an antenna portion (430) for communicating the liquid information stored in the information storing portion (410) between the information communicating member (400) and the liquid ejection apparatus in a wireless manner; and a base member (440) on which the information storing portion and the antenna portion (430) are disposed. The base member (440) has an electric insulating property and an ultraviolet ray shielding property.
摘要:
A plurality of terminals are provided on a circuit board of an ink cartridge, and a plurality of lines are formed by contact portions of the plurality of terminals. In a first line among the plurality of lines, contact portions of two terminals for detecting attachment are arranged, and a contact portion of a power supply terminal is arranged therebetween. The first line may be located at a leading side when the ink cartridge is moved in a predetermined direction and is mounted on a printing device, or the first line may be the line closest to an opening of an ink supply port, or the first line may be the line closest to an ink supply needle.
