本発明は入力装置の改良に係シ、特に異なる原稿を同一
の検知手段によって読取る入力装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an improvement in an input device, and particularly to an input device that reads different documents using the same detection means.
従来ファクシミリ装置等に用いられる画像入力装置とし
ては
(1) ドラムに原稿を取付けメイクロイツクミラー
によって色分解読取シを行う方式。Conventional image input devices used in facsimile machines and the like include (1) a method in which a document is mounted on a drum and the color separation is read out using a makeroit mirror;
(2)密着センサにストライプフィルタを取付は色分解
読取シを行う方式。(2) A method in which a stripe filter is attached to the close contact sensor performs color separation and reading.
(3)1次元ラインアレイセンサを3本並列に配置し、
色分解フィルタを重ね画像読取りを行う方式。(3) Three one-dimensional line array sensors are arranged in parallel,
A method of reading images by overlapping color separation filters.
等の方式が存した。There were other methods such as
ところが最近、画像入力装置に対して紙等の印刷物原稿
とフィルム原稿との両者の処理をできることが強く要望
されている。However, recently, there has been a strong demand for image input devices to be able to process both printed matter originals such as paper and film originals.
しかるに前述した3つのタイプの画像入力装置では以下
に示す欠点を有する。However, the three types of image input devices described above have the following drawbacks.
(1)の方式ではドラムに原稿を取付けるので原稿がフ
ィルム又はシート原稿に限定されスライド及び本等の原
稿からの情報を読みとることは不可能である。In the method (1), since the original is mounted on a drum, the original is limited to a film or sheet original, and it is impossible to read information from originals such as slides and books.
(2)の方式は通常セルフオフ等のレンズアレ・イヲ密
着センサとして使用し、等倍でセンサ上に結像させるの
であるが、原稿面の分解能は12 pe1程度が限界で
ある。ところがフィルムを読取る為には50 pa1程
度で読取る必要があるので、セルフォック等の7レイレ
ンズで印刷物とフィルムとを兼用して読取ることは困難
である。The method (2) is usually used as a close-contact sensor such as a self-off lens array and forms an image on the sensor at the same magnification, but the resolution of the document surface is limited to about 12 pel. However, in order to read film, it is necessary to read it at about 50 pa1, so it is difficult to read both printed matter and film using a 7-ray lens such as SELFOC.
(3)の方式は比較的欠点の少ない色分解入力系を形成
出来る方式であるが、従来のこの方式の画像入力装置に
おいては、フィルムと印刷物を同一装置にて読取るもの
はなかった。これは原稿サイズが異なりすぎるためと、
フィルム入力の場合はネガフィルムもあるので印刷物原
稿と異なシ、処理が複雑化するためと考えられる。The method (3) is a method that can form a color separation input system with relatively few defects, but no conventional image input device of this method reads film and printed matter in the same device. This is because the original sizes are too different.
This is thought to be due to the fact that in the case of film input, negative film is also used, which is different from printed originals, making the processing more complicated.
この為印刷物原稿とフィルム原稿を別々の装置により入
力することが考えられるが全体の装置構成が大きくなシ
価格的にも高いものとなる。For this reason, it is conceivable to input the print original and the film original using separate devices, but the overall device configuration is large and the cost is also high.
又原稿走査にはCODの様々1次元センサアレーを使用
するのが一般的であるが、画像は2次元情報のため一方
向は1次元センサによりミ予約走査が可能となるが、他
方向は機械的に移動させねばならず読取り精度が劣ると
いう欠点があった。In addition, it is common to use COD's various one-dimensional sensor arrays for document scanning, but since the image is two-dimensional information, it is possible to perform scheduled scanning in one direction using a one-dimensional sensor, but in the other direction, it is possible to use a machine. This has the disadvantage that the reading accuracy is poor because it has to be moved in a specific manner.
そこで本発明の目的は前記欠点を解消すべく反射原稿(
例えば印刷物等)と透過原稿(例えばフィルム等)を同
一のセンサにより高精度に、検知でき、更に高精細化が
可能な走査方式を有する入力装置を提供することにある
。Therefore, an object of the present invention is to solve the above-mentioned drawbacks.
It is an object of the present invention to provide an input device that can detect a transparent document (for example, a printed matter, etc.) and a transparent original (for example, a film, etc.) with high precision using the same sensor, and has a scanning method that can further increase the definition.
前記目的を達成すぺ〈本発明は異なる原稿を同一の検知
手段によって検知することを特徴とする。To achieve the above object, the present invention is characterized in that different documents are detected by the same detection means.

る。A film cassette insertion slot 28 is provided on the top surface of the housing 2 . At the bottom of the film cassette insertion slot 28 is a second motor which is movable in the direction E in the figure by a second motor (not shown).
A second illumination means 34 consisting of a light source 30 and a second reflective shade 32 is provided. 36 is a film which is a second read force medium;
A film holder 38 holds the film 36 and fixes the film surface. As a result, when the film 36 is moved and scanned, it is possible to prevent pique due to patter on the film surface due to the depth of the lens, and the feeding of the film 36 becomes stable. While the film 36 is moved in the direction F in FIG. 2 by a third motor (not shown), the film 36 in the film holder 38 is irradiated with light emitted from the second illumination means 34. The light transmitted through the film 36 is the third
It is reflected by the mirror 46, passes through the lens system 42, is partially reflected by the half mirror 44, is reflected by the rotary mirror 26 located at the dotted line in FIG. 2, and is detected by the sensor array 22. A part of the light passes through the half mirror 44, and that light is transferred to the fourth mirror.
After being reflected by a mirror 46 and diverted, the image is formed on a monitor 50 provided on the top surface of the housing 2 via a second lens system 48, allowing a person to observe the position of the film, the degree of picketing, etc.

This is performed by the sensor array 22 while irradiating the sensor array 6 in a linear manner. Therefore, at the time of film reading 9, the second illumination means 34,
The mirror system such as the third mirror 40, the third lens 42, and the sensor array 22 are fixed.

Accordingly, g2 is placed at the position shown by the solid line in the figure. In this case, the light reflected by the reflective original 4 is detected by the sensor array 22 without being reflected by the rotating mirror 26.

同志の合成が可能となる。Further, in this embodiment, the two originals are a reflective type original and a transmissive type original, but both can be made into a transparent type original or a reflective type original. Also, by using a half mirror as the rotating mirror 26 at this time, it becomes possible to combine the transmission-type originals and the reflection-type originals.
