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.

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.

Digital dial gauge

A digital indicator () includes: a main body (); a spindle () being axially slidable and having a contact portion () on one end, the contact portion abutting a to-be-measured portion; a detector () that detects an absolute displacement amount of the spindle () relative to the main body (); and a display () that digitally displays the displacement amount of the spindle () relative to the main body () detected by the detector. The spindle () is slidable in a direction away from the contact portion () beyond the detectable range of the detector ().
