に着脱可能になっている。1 and 2 show a first embodiment of the present invention. In the figure, 2 is a mounting table on which the image 1 to be read is placed, 3
Is a camera (imaging unit) having a photoelectric conversion unit for reading the image 1, and 4 is a support member for supporting the camera 3.
An illumination unit (not shown) that illuminates the mounting table 2 is provided in the support member 4. A direct current lighting unit is used for this lighting unit so as to prevent flickering due to flicker. Reference numeral 6 denotes a light shielding plate provided with a concave groove m that fits into the horizontal support portion 4a of the support member 4. The light shield plate 6 is attachable to and detachable from the support member 4. That is, all or part of the upper surface of the horizontal support portion 4a of the support member 4 is made of a magnetic material such as iron. On the other hand, a magnet 7 is attached to the concave groove m of the light shielding plate 6 as shown in FIG. Therefore, when the concave groove m is fitted in the horizontal support portion 4a of the support member 4, the light shielding plate 6 is attracted and fixed to the horizontal support member 4a by the magnetic force of the magnet 7. In this state, the concave groove m of the light shielding plate 6 is just fitted to the horizontal support portion 4a so that the end portion 6a does not rotate and come off even if force is applied to the end portion 6a. However, it can be removed by raising it with some force. The light-shielding plate 6 has the structure as described above, and thus the support member 4 is provided.
It is removable.
次に作用を説明する。Next, the operation will be described.
この装置を使用する際、部屋の照明光が原稿１に正反射

のような不都合が起きない場合には、遮光板６を取り付
けないで、あるいは取り外して使用することができるの
で、原稿１の取り扱いや原稿１への書込み等が容易にな
る。When this apparatus is used, when the illumination light in the room is specularly reflected by the original 1 and the original 1 cannot be read cleanly, or when the influence of the flicker of the illumination cannot be removed by the illumination unit in the apparatus, the light shielding plate 6 Should be attached to the support member 4. If such inconvenience does not occur, the light-shielding plate 6 can be used without being attached or removed, so that handling of the document 1 and writing to the document 1 are facilitated.
一方、装置を使用しない時には、遮光板６を取り外して
載置台２に重ねるか、支持部材４に立てかけるかすれば
コンパクトにまとめられるので、収納スペースをとらな
いし、運搬するにも嵩張らないので持ち易くなる。On the other hand, when the apparatus is not used, it can be compacted by removing the light shield 6 and stacking it on the mounting table 2 or by leaning it against the support member 4, so that it does not take up a storage space and is not bulky to carry, so it is easy to hold. .
