摘要： PROBLEM TO BE SOLVED: To enable correct recognition of codes. SOLUTION: Since printing is carried out by nozzles excluding nozzles 3a and 3b at one end part among nozzles 3a-3p of a printer head 2, codes printed by scanning the printer head 2 are prevented from overlapping for every scanning as indicated by a part surrounded by an elliptic part in the drawing. Codes are thus correctly printed. Moreover, since code columns 11 for synchronization are printed, a position of printed dots can be correctly detected, enabling correct recognition of codes.

摘要： PROBLEM TO BE SOLVED: To make accurately readable a two-dimensional dot code. SOLUTION: Timing marks 32L and 32R are printed on the left and right sides of the data marks 33 of a two-dimensional dot code in every row. The existence/absence of the data mark 33 is judged with the position on a straight line obtained by connecting the centers of the marks 32L and 32R at its left and right edges as a reference.

摘要： PROBLEM TO BE SOLVED: To communicate with the opposite party by simply storing data with which the opposite party is specified. SOLUTION: A code reading part 11 reads a dot code including data for specifying the opposite party. A memory 35 stores the data for specifying the opposite party. A communication part 32 communicates with the opposite party on the basis of the data stored in the memory 35.

摘要： PROBLEM TO BE SOLVED: To represent plural kinds of information with one code by obtaining a 1st code when an element color is read with 1st color light and obtaining a 2nd code when the element color is read with 2nd color light. SOLUTION: A data processing part combines plural kinds of inputted data and generates a color pattern corresponding to the combination. In color decision processing of an element, a code 1 corresponding to 1st data is a code capable of being read with red light, and a code 2 corresponding to 2nd data is a code capable of being read with green light. When both the codes 1 and 2 are '1', the color of a print element is defined as white (W). When the code 1 is '1' and the code 2 is '0', a print element is defined as magenta (M). When the code 1 is '0' and the code 2 is '1', a print element is defined as cyan (C). When both the codes 1 and 2 are '0', a print element is defined as black (BL).

摘要： PROBLEM TO BE SOLVED: To correctly read dots in a small printing area by arranging the dots at a pitch being about two times as long as their diameter between respective columns and also shifting dots to a column direction from the arrangement positions of dots in a 1st column by almost the diameter of a dot in a 2nd column to arrange them. SOLUTION: A printing part performing printing on a card defines the value of the best resolution pitch as, e.g. P0. Then, in a pixel (dot), its diameter becomes a value being equal to or slightly larger than the value P0. Even though the dot is not a perfect circle but regarded as a circle. Then, the diameter of the dot is defined as equal to the value P0 of the best resolution pitch. When the printing part prints a two-dimensional code on a card, it defines a length being about two times as long as the dot diameter as a printing pitch P in both horizontal and vertical scanning directions. However, when dots are observed in the direction of each column, a dot adjacent to the left or right side is shifted in the column direction for the value P0 of the best resolution pitch.

摘要： PROBLEM TO BE SOLVED: To detect an overlapped feeding of papers without being influenced by a thickness of the papers and an environment of the surroundings. SOLUTION: A supersonic wave transmitted from a supersonic transmitter 1 is received by a supersonic receiver 2 through papers 4. A receipt signal is inputted to an extraction part 19 and is compared with a phase of a standard signal which a standard signal reproducing part 18 outputs and then is converted to a signal of level corresponding to a phase difference. The signal of level corresponding to the phase difference is compared with a threshold value set in a threshold value setting part 20 in a comparator 21. When only one sheet of the paper 4 is fed, the comparator outputs a signal of a high level and when the paper 4 is overlapped-fed, the comparator outputs a signal of a low level.

摘要： PURPOSE:To allow even a personal computer with a slow processing speed to read picture data by continuously reading an FIFO with a request signal produced when an address by a read address counter and an address by a write address counter are in noncoincidence. CONSTITUTION:A write address counter 15 is sequentially incremented, parallel picture data read from a handy image scanner 10 are written in a buffer memory 13 of an FIFO 12 and read by a personal computer 13 with a slow processing speed through a read address counter 16. After an output of the counter 16 whose processing speed is slow based on the difference from the processing speed is made coincident with an output of the counter 15, they are made noncoincident afterward. The noncoincidence is detected by an exclusive OR circuit 17, the personal computer 14 is controlled to read the data continuously independently of the read clock after the noncoincidence and the system acts like an interface for a handy image scanner in which the data are read by the personal computer with a slow processing speed.

摘要： PROBLEM TO BE SOLVED: To prevent an image from being expanded or contracted. SOLUTION: An amplifier circuit 16 amplifies an analog image signal outputted from a CCD 14, an A/D converter 17 applies A/D conversion to the amplified signal and a buffer 42 stores the signal temporarily. A line counter 41 counts how many lines of analog image signals the CCD 14 outputs. A line management circuit 32 outputs image data by specific 4 lines among the image data stored in the buffer 42 to an image memory 18 to thin the image data.

摘要： PROBLEM TO BE SOLVED: To perform a binarization capable of eliminating random noise. SOLUTION: In a step S2, a histogram is generated from read-in picture data; and in a step S3, a threshold to binarize data to a maximum level below the normal distribution due to the random noise, and five threshold Th1 to Th5 in total are set on the basis of this set threshold. In a step S4, areas of which the parts judged to be black are made wider by changing the threshold from the threshold Th3 to the threshold Th1 and the parts judged to be black are made narrower by changing the threshold from the threshold Th3 to the threshold Th5 are detected, and detected areas are processed as code pictures (step S5), and the other areas are processed as pictures affected by the random noise (step S6).
