Abstract: The X-ray processing device comprises a work table on which a processing object is placed, X-ray processors irradiating the processing object placed in a given processing zone on the work table with an X-ray for processing, a pressing member, and X-ray shielding sheets. The pressing member presses and collapses any remaining raised edges at the sides of the processing object. The X-ray shielding sheets are provided on the side of the pressing member that is closest to the processing zone and shield the X-ray from the X-ray processors.

Abstract: A printed substrate holding device includes: a base member including a recess portion including: a bottom portion; and a side wall portion provided in the bottom portion; and a printed substrate held in the recess portion and having a rigidity, wherein the side wall portion includes a holding portion holding a first surface of the printed substrate, the bottom portion includes a supporting portion supporting a second surface of the printed substrate, the printed substrate slides on the bottom portion and is inserted between the supporting portion and the holding portion, and is held in the recess portion, and the printed substrate is held in the recess portion while being bent.

Abstract: An aperture device includes: a board including an opening; a step motor capable of stopping every predetermined rotational angle; an output member including first and second pins and rotating a predetermined range by the step motor; and first and second blades driven by the output member with first and second blades respectively engaging with the first and second pins, linearly moving in opposite directions, and covering the opening to adjust an aperture area of the opening; wherein an X-axis indicates a phantom line passing through a rotational center of the output member and extending in the moving directions of the blades, and when the aperture area is a minimum, an angle between a directional line, which connects the rotational center with the first pin, and the X-axis is from minus 20 degrees to plus 30 degrees.
