  • Publication number: 20140168342
    Abstract: A portable thermal printer includes a housing and an anti-skew unit. The housing is provided with a thermal printer head and a platen roller, and is configured to convey a paper between the thermal printer head and the platen roller. The anti-skew unit inside the housing is configured to contact both side edges of the paper in a width direction to prevent the paper, which is being conveyed, from skewing, and the setting of the width of the paper by the anti-skew unit is configured to be adjustable from outside the housing.

  • Patent number: 8755487
    Abstract: An X-ray imaging system includes first to third absorption gratings. Initially, the third absorption grating is disposed in a Z axis orthogonal to a detection surface of a FPD, and the position of the third absorption grating is adjusted in ?x and ?y directions based on a dose of X-rays having passed through the third absorption grating. Then, the first absorption grating is disposed in the Z axis so as to produce a moiré pattern. The position of the first absorption grating is adjusted in the ?x and ?y directions so that a frequency of the moiré pattern detected by the FPD becomes uniform. Then, the position of the first absorption grating is adjusted in a Z or ?z direction so that the FPD loses the detection of the moiré pattern. After that, the second absorption grating is aligned in a like manner as the first absorption grating.

  • Patent number: 8632247
    Abstract: A radiation imaging system includes an X-ray source, first and second absorption gratings disposed in a path of X-rays emitted from the X-ray source, and an FPD. The second absorption grating is slid stepwise in an X direction relative to the first absorption grating. Whenever the second absorption grating is slid, the FPD captures a fringe image. From the captured plural fringe images, an intensity modulation signal of each pixel is obtained. A positional deviation detector calculates an amplitude value of the intensity modulation signal. The positional deviation detector compares a measurement of the amplitude value with predetermined first and second threshold values. If the measurement is less than the first threshold value, a warning signal is outputted. If the measurement is less than the second threshold value, an error signal is outputted.
