Abstract: A dust-proof structure for a measuring tool, includes: a case provided with an opening formed through a surface opposed to a protection plate thereof; a solar panel accommodated in the case through the opening of the case; an intermediate panel pressing an outer circumferential portion of the solar panel against a bottom wall of the case; a display device disposed at an inward portion of the intermediate panel and opposed to the solar panel with a gap; a cover attached to close the opening of the case; a screw used to secure the cover and the intermediate panel to the case; and a temporary-fixing unit disposed between the intermediate panel and the case, the temporary-fixing unit temporarily fixing the intermediate panel to the case while the outer circumferential portion of the solar panel is pressed against the bottom wall of the case.

Abstract: A position detection encoder includes a scale that has a position detection pattern and a linear pattern that is formed in a direction parallel to a length direction of the position detection pattern; and a position detector generating a position detection signal with a different value due to a displacement of the position detection pattern in the length direction. In the position detector, a position confirmation pattern is formed that includes two markers arranged at an interval equal to or less than an offset tolerance value for a positional relationship of the position detector and the scale in a width direction of the position detection pattern.
