する平行定規装置。 Vertical rails are provided on both the left and right sides of the drawing board, two overlapping intermediate rope pulleys are arranged at the upper ends of these vertical rails, and one end rope pulley is arranged at the lower end of each vertical rail. A rope for attaching a cursor is stretched between the end rope pulleys in an endless ring, and the middle of the rope is wound around each of the two intermediate rope pulleys, so that the rope moves simultaneously in the same direction along the vertical rails on both the left and right sides. In a parallel ruler device in which a cursor is attached and a scale placed on the drawing surface is provided between the cursors, an end rope pulley is connected to the two intermediate rope pulleys which are overlapped at a predetermined interval. 1. A parallel ruler device, characterized in that the device is inclined so that the distance between the rope pulleys and the distance between the ropes stretched over the end rope pulleys are approximately equal.
