本発明は、文書画等の原稿を読取る装置に関し、特に文
書画等の原稿の位置座標を正確に調整することができる
原稿講取り装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for reading original documents such as document drawings, and more particularly to a document reading apparatus capable of accurately adjusting the position coordinates of original documents such as document drawings.
文書画等を光走査し、電気信号に変換する装置としては
、例えばファクシミリ等があるが、これらは文胃画等に
含まれる情報を伝達することに重点がおかれているので
、情報が文書画等のどの位置にあるかは考慮する必要が
ない。それ故に、光亀変換素子の走査する座標に対する
文書画等に含まれる情報の座標のずれは、相当の範囲に
わたって許容されている。従って、文書画等を装置にセ
ットするに当っては、文賛画等の適当な１辺又は２辺を
装置に刻まれた目盛り等に合わせて、例えば平面ガラス
の上に直くか円筒に巻き込ませれば良かった。Examples of devices that optically scan document images and convert them into electrical signals include facsimile machines, but these devices focus on transmitting the information contained in document images, etc. There is no need to consider the position of the image, etc. Therefore, a shift in the coordinates of information contained in a document image or the like with respect to the coordinates scanned by the optical turtle conversion element is allowed over a considerable range. Therefore, when setting a document or painting on the device, align one or two sides of the document or painting with the scale etched on the device, and place it directly on a flat glass or in a cylinder, for example. I should have gotten him involved.
ところが、技近、文書画を読取って暗号化し、これをさ
らに復号化するような装置が提案されており、このよう
な菱直の場合には暗号化時の原文書画の座標と復号化時
の贈号化画像の座標とを精密に合わせることが必要とな
る。However, a device has been proposed that reads the document image, encrypts it, and then decrypts it. It is necessary to precisely match the coordinates of the gifted image.
なぜならば、仮に両者の座標位置に狂いがあると復号化
時に特有のノイズを発生したり、著しい場合には復号化
が不可能にさえなるからである。しかしながら、従来の
論取り装置では文書画等に含まれる情報の座標を論取り
走査系の座標に正しく合わせることは非常に難しく、事
実上不可能である。This is because, if there is a discrepancy in the coordinate positions between the two, peculiar noise will occur during decoding, or in severe cases, decoding may even become impossible. However, with conventional discussion devices, it is very difficult, and virtually impossible, to correctly match the coordinates of information contained in a document image, etc., to the coordinates of the discussion scanning system.
本発明は、文書画等に含まれる情報の座標を謙取るシス
テム側の走査する座標に容易にかつ正確に合わせること
ができる様に改良することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to improve the ability to easily and accurately match the coordinates of information contained in a document image or the like to the scanning coordinates of a scanning system.

を読取るようにしたものである。The document 1 is illuminated by the illumination device 6, and information is imaged onto the scale plate 9 by the movable reflector 4, the lens 7, and the fixed reflector 5. For example, a grid as shown in FIG. 3 is marked on the scale plate 9 as an index, and the position is determined and fixed in advance so that the position of the image discussion device 8 and the grid correspond exactly. ing. By adjusting the position adjustment mechanism dials 3a, 3b, and 3c in the X, Y, and rotational directions so that the specific coordinates of the projected image match the specific coordinates of the scale plate 9, the original 1 is aligned with the reference scale. This means that the plate 9 has been correctly aligned to the predetermined position. Therefore, if the movable reflecting mirror 4 is then raised to the position indicated by the chain line 4' in FIG. will match correctly. FIG. 4 shows another embodiment of the present invention, in which a fixed reflector 4A is used instead of the movable reflector 4, and after the document position adjustment is completed in the same manner as described above, the platen 2 and the fixed reflector are A second movable reflecting mirror 10 is inserted between the mirror 4A and the information on the document is reflected and deflected upward or downward from the paper surface, and then the information is read by a discussion device 8 provided above or below the paper surface. It is something.
