The conversion circuit includes a plurality of driver circuits coupled to a plurality of strobe signals from at least one strobe signal generator, wherein each of the plurality of driver circuits comprises a plurality of gating groups respectively coupled to the plurality of strobe signals, wherein each of the plurality of gating groups includes a plurality of gate units respectively coupled to a plurality of heating elements wherein at least one gate unit controls at least one coupled heating element according to a corresponding strobe signal. | 08-02-2012 |
| 20150085054 | CONTROL DEVICE, PRINTER, AND CONTROL METHOD OF A PRINTER - When printing a first line, a control device controls energizing heat elements corresponding to pixels where a dot is formed on a second line that is printed continuously. A control device of a thermal head having a plurality of heat elements arranged in a line includes: an acquisition unit that acquires information of pixels forming dots when printing the second line during line printing of a first line and a second line by continuous line printing by the plural heat elements; and an energization control unit that controls energizing the heat elements during the first energizing period based on image data related to printing the first line when printing the first line, and controls energizing the heat elements in the second energizing period when printing the first line based on the image data related to printing the first line and the pixel information acquired by the acquisition unit. | 03-26-2015 |

| 20100253758 | THERMAL PRINTER - When printing is performed by dividing a thermal printer head into segmented blocks, the number of dots to be printed in one line is changed, depending on the case, high-speed printing with a small division number of the segmented blocks, or low-speed printing with a large division number of the segmented blocks. When the division number of the segmented blocks is large and printing is performed at a low speed, paper feeding within one line is performed by multiple pitches to prevent the paper sheet from halting in one line, and energization is performed for each pitch to prevent occurrence of gaps between dots and between lines, by increasing the number of dots to be printed in one line. In the multiple pitches in one line, the ratio of energization amount to be fed in each pitch is changed to reduce a difference in density among pitches in one line. Accordingly, when printing is performed by using segmented blocks of the thermal printer head, even though the division number of the segmented blocks is large and printing is performed at a low speed, printing without generating a gap between dots is possible. | 10-07-2010 |

| 20100134580 | THERMAL PRINTER AND DRIVE CONTROL METHOD OF THERMAL HEAD - A thermal printer includes a first thermal head which is so provided as to be brought into contact with one side of a paper, a second thermal head which is so provided as to be brought into contact with the other side of the paper, and a controller. The first thermal head energizes a plurality of heater elements to print dot image data on one side of the paper. The second thermal head energizes a plurality of heater elements to print dot image data on the other side of the paper. The controller is configured to shift the energization times between the first thermal head and second thermal head. | 06-03-2010 |
