  • Patent number: 9332623
    Abstract: A high-voltage discharge lamp illumination device comprises a pulse generation part which generates pulse waves, and a power supply part which receives a DC voltage and converts the DC voltage into the AC current in correspondence to a frequency of the pulse waves so as to supply the AC current to the lamp. The pulse generation part repeats a cycle of outputting a first pulse wave over a first period, and thereafter outputting a second pulse wave having a lower frequency than the first pulse wave over a second period shorter than the first period. The pulse generation part returns to the cycle after outputting a third pulse wave having a frequency which is further lower than the second pulse wave in place of the second pulse wave, at a predetermined timing.

  • Patent number: 9162487
    Abstract: An arrival of a joint member at a detection position provided at an upstream side of a recording unit on a transportation path is detected. A second distance, which is a distance from the detection position to the recording head along the transportation path, is longer than a first distance, which is a distance of a transportation of the continuous medium in the case where, because of an existence of a liquid already landed on an area of the continuous medium at the detection time, the area being located at a position being on the transportation path and facing the recording unit, the continuous medium is transported during a period until at least hardening of the liquid is completed by a light radiation portion.

  • Patent number: 9122961
    Abstract: A mask generating unit generates a show-through area mask in accordance with inverted front printed image data, obtained by inverting front printed image data in a horizontal direction, and back printed image data. Then, a determining unit inspects a show-through area of the back inspecting image data corresponding to the show-through area mask with a show-through inspection threshold. Consequently, an area where the show-through exists with high possibility is inspected with the looser show-through inspection threshold. This achieves suppression of determination error due to the show-through. On the other hand, an area where no show-through exists with high possibility is inspected with a tight normal inspection threshold. This achieves accurate determination of printing error. As a result, accurate printing inspection is obtainable even to web paper with the show-through.
