<p>PURPOSE:To enable simple execution of input to CAD without removing a drawing from a table after a drawing operation is ended, by integrating a scanner with an adjustable parallel ruler device. CONSTITUTION:A longitudinal rail 12 which has a relation of a right angle to a lateral rail 8 fixed in the upper edge part of a table 4, which is connected thereto slidably and which has a length making it possible to traverse almost the whole area of a drawing range of the table 4, straight rulers 22 and 24 which are fixed removably to a ruler fitting plate 20 of an operation head 18 connected movably to the longitudinal rail, and a scanner 26 disposed on the longitudinal rail 12 oppositely to the surface of the table 4, are provided. A figure information drawn on paper on the table 4 by using an adjustable parallel ruler device 6 can be turned into electronic data by turning ON the scanner 26, by moving the longitudinal rail 12 manually from left to right along the surface of the table 4 and by scanning the surface of the table 4 by the scanner 26.</p> |
