Patent attributes
To provide a parallel ruler device with which it is easy to obtain a plate material of a constant width having parallel sides. Also, to make it possible to easily carry out a precision adjustment of an amount of parallel movement of a ruler face by means of a visual observation. Also, to enable a precision adjustment of a desired dimension in both a positive direction and a negative direction with a position fixed once as a base point. In a parallel ruler device which includes a moving body movable along a sliding portion provided on a main body, and in which the moving body has a sliding counterpart making contact with the sliding portion, and is configured in such a way that a ruler face set in a portion other than the sliding counterpart moves in parallel along with the movement of the moving body, an inclined sliding portion 12 is set in a direction intersecting a longitudinal direction of the main body 11, a direction of the ruler face 17 of the moving body is set in a direction intersecting that of the sliding counterpart 16 of the moving body 15 which slides along the inclined sliding portion, and the ruler face of the moving body is configured in such a way as to move away from or near to the main body along with the movement of the moving body.
