  • Printer apparatus including a fixed blade pushed toward a movable blade
    Patent number: 9056508
    Abstract: A printer includes a fixed blade block and a movable blade block. The fixed blade block includes an installing member including a rotation shaft, a fixed blade installed in the installing member, a retaining member, and a spring attached to the installing member in a rotatable state with respect to the rotation shaft. The spring includes a first contact part that contacts with the fixed blade and a second contact part that contacts with the retaining member. The movable blade block includes a movable blade that is movable toward the fixed blade. When the fixed blade block and the movable blade block are connected, the retaining member presses the second contact part, causing the spring to rotate and push the fixed blade toward the movable blade.

  • X-RAY TOPOGRAPHY APPARATUS
    Publication number: 20150146858
    Abstract: Disclosed is an X-ray topography apparatus including an X-ray source, a multilayer film mirror, a slit, a two-dimensional X-ray detector, and a sample moving device that sequentially moves the sample to a plurality of step positions. The X-ray source is a minute focal spot. The multilayer film mirror forms monochromatic, collimated, high-intensity X-rays. The direction in which the multilayer film mirror collimates the X-rays coincides with the width direction of the slit. The step size by which the sample is moved is smaller than the width of the slit. The combination of the size of the minute focal spot, the width of the slit, and the intensity of the X-rays that exit out of the multilayer film mirror allows the contrast of an X-ray image produced when the detector receives X-rays for a predetermined period of 1 minute or shorter to be high enough for observation of the X-ray image.

  • Rotary cutter unit and printer device having the unit
    Patent number: 9032850
    Abstract: A simple and compact rotary cutter unit capable of detecting a home position of a rotary cutter, and a printer device having the rotary cutter unit. A radially outwardly extending fin-shaped detected member is arranged on an end portion of the rotating blade opposed to a second gear of the rotating blade. A photosensor is arranged within a main frame of the printer device so that the photosensor may detect the fin-shaped member when the rotating blade is positioned at the home position. The fin-shaped member and the photosensor are not positioned outside relative to both ends of the rotating blade in relation to the direction of the rotational axis of the rotating blade. Therefore, it is not necessary to increase the width of the printer device due to the presence of the fin-shaped member or the photosensor, whereby the printer device may be compactly constituted.
