Abstract: To simplify a data reading apparatus for two-dimensional code data, a line sensor detection unit (30) for reading two-dimensional data includes an optical fiber band cable (3) bundling multiple optical fibers (31) of specified diameter in a band, and an upper end of the fibers is connected to a line sensor element (2) unit incorporated in the reading apparatus (S), and a lower end of the fibers is disposed opposite to an opening (11) of a specified size in the region of one or more two-dimensional code data in the bottom of the reading apparatus (S). The line sensor detection unit (3) including the optical fiber band cable (3) is disposed reciprocally parallel along the surface to be detected in an orthogonal direction, and the line sensor detection unit (30) is set movable within the range of the opening (11). A detection unit moving device (4) is disposed so as to read the two-dimensional code data.

Abstract: A system and method for locating and reading digital data in data regions within a data field disposed on a surface of an object to be identified include the capability of compensating for optical or physical distortions of the data field as viewed by an optical reader. The data field is defined by X-axis and Y-axis intersecting basic lines disposed at a predetermined angle with respect to each other and a corner mark disposed on the opposite side of the data field from those basic lines. A plurality of positions marks for marking predetermined distances between a plurality of imaginary X and Y axis internal lines are also provided. The positions of the imaginary X-axis internal lines within the data field are determinable from their spacings and angles with respect to the Y-axis basic line. The positions of the imaginary Y-axis internal lines are determinable from their spacings and their angles with respect to the X-axis basic line.

Abstract: A method for decoding and processing at high speed by reading two-dimensional code symbol marks by a code reader in a small memory capacity. The X-axis side indication line 4 or Y-axis side indication line 5 in an information area 8 recording the code symbol mark 2 is read by the code reader 3, and division marks 7 recorded on the X-axis side indication line 4 or Y-axis side indication line 5 are detected. At every interval of dividing the division marks 7 in the Y-axis direction or X-axis direction by a specific integer value, the code mark 9 of the binary signal recorded in the information are 8 is sequentially read by the code reader 3 up to an end part of the Y-axis side indication line 5 or the X-axis side indication line 4 and the region formed in each square, of which one side is the interval of the division mark 7 is read by the code reader 3, or the length between the division codes divided by an integer value is processed, thereby decoding the code symbol mark 2.

Abstract: An identification code sheet includes of codes of merchandise, a character string or a document etc. The sheet can be read by a sensor. The identification code sheet including a representation area defined by both a X-axis and a Y-axis intersecting mutually either orthogonally or skewedly and sub-areas of identification code printed in are representation area. The said representation area is divided into sixteen or more sub-areas, in each of which an identification code of encoded indicia is recorded. With the coding and method much more informations relative to the conventional techniques may be handled and more particularly much more Kana-Kanzi, Arabic and Chinese letters etc. as well as numerical characters, symbols, and alphabets may be represented which can be easily read.

Abstract: An identification code sheet for representing codes for merchandise, or the like and a method for reading the identification code sheet. The identification code sheet for identification of merchandise or the like, according to the invention, comprises a representation area defined by both a X-axis and a Y-axis intersecting mutually either orthgonally a skewedly and sub-area of identification code printed in said representation area. According to the invention, said representation area is divided into sixteen or more sub-areas, in each of which an identificiation code of signal codes of binary type is recorded. In this manner, more information may be stored compared to conventional techniques and more particularly more Kana-Kanzi, Arabic and Chinese letters etc. as well as numerical characters, symbols, and alphabets may be represented and easily read.
