PURPOSE:To facilitate the retrieving of an assembly drawing to which similar drawings are produced, by showing the retrieving key instantly and in a figure through an electronic computer. CONSTITUTION:An A/D converter 3 converts a plan pattern and its attached character trains, symbols, etc. for significance into electronic signals along with the positioning to the plan pattern. These electronic signals are stored to an electronic signal storage device 7 via a control electronic computer 10. An electronic computer system 12 supplies the information on the electronic signal corresponding to the plan and then processes it by a prescribed program. Then the system 12 displays a pattern corresponding to the above-mentioed information to a display 5 and at the same time compares the information corresponding to the plan with the information stored in the device 7. If both informations have coicidence with each other at some part, the drawing number corresponding to the information of the coincident part is read out of the drawing number that is set previously for each information. A drawing retrieving device 11 retrieves the corresponding drawing on the basis of the drawing number read out through the system 12. |
