【考案の詳細な説明】
本考案は前後に２分割された原稿圧板即ち原稿
押え板を有する新規な複写機用原稿圧着装置を提
供することにある。DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to provide a novel document pressing device for a copying machine, which has a document pressing plate, that is, a document pressing plate, which is divided into front and rear parts.
従来、複写装置においては弾性部材を常時機械
本体に接触させるか又は本体ケースに凸部を設け
て原稿の落下を防止していた。しかしながら前者
においては圧板の開閉時に負荷が加わり、操作性
が悪くなる欠点がある。又、後者では原稿の落下
防止だけの為に本体ケースにわざわざ凸部を設け
る無駄がある。 Conventionally, in a copying apparatus, an elastic member is kept in constant contact with the machine body or a convex portion is provided on the main body case to prevent the document from falling. However, the former has the disadvantage that a load is applied when opening and closing the pressure plate, resulting in poor operability. Moreover, in the latter case, it is wasteful to provide a convex portion on the main body case just to prevent the document from falling.
そこで、本考案は従来の複写装置の上記諸欠点
を克服する為になされたものである。 Therefore, the present invention has been devised to overcome the above-mentioned drawbacks of conventional copying apparatuses.
本考案の目的は原稿圧着装置を開けることを利
用して受止部材を原稿載置面に圧接する事により
原稿の落下を防止しうる構造が簡単でしかも操作
性のよい原稿圧着装置を提供することにある。 The purpose of the present invention is to provide a document crimping device which has a simple structure and is easy to operate, which can prevent the document from falling by pressing the receiving member against the document placement surface by opening the document crimping device. There is a particular thing.

なる事は上述した通りである。 FIG. 1 is a schematic side sectional view showing a conventional document pressing device, and FIG. 2 is a view similar to FIG. 1 showing a document pressing device according to the present invention. In the figure, 1 is a front document pressure plate or a presser plate, 2 is a rear document pressure plate or a presser plate, 3 is a hinge, 4 is a rotation shaft, and 5 is a support shaft. The front document pressing plate 1 is opened around the hinge shaft 3' and stops at an angle where it abuts the side surface of the rear document pressing plate 2. Thereupon, both the front and rear document pressure plates are rotated as a unit around the rotating shaft 4 and opened.
As mentioned above, in this type of document pressing device, a large load is applied to the rotary shaft 4 when the pressure plate is opened and closed, resulting in poor operability.

によつて元の状態に復帰する。 As mentioned above, FIG. 2 is a diagram showing a preferred embodiment of the present invention, and FIG. 3 is an enlarged partial side sectional view showing the receiving portion thereof in an enlarged manner. One end of the receiving actuation electric wire 6 is fixed to the lower protrusion 13 of the front document pressure plate 1, and the other end is fixed to the upper end of the receiving member mounting bracket 10 via an optional spring 8. Return spring 1
2 has one end attached to the upper end of the receiving member mounting bracket 10, and the other end attached to the lower protrusion 14 of the rear document pressure plate.
Fixed to . Reception member mounting bracket 10
A receiving member 9 made of an elastic material is attached to the lower surface of the holder 9 by an arbitrary method. When the front document pressure plate 1 is opened upward, the receiving actuation electric wire 6 is thereby pulled. The spring 8 is used to maintain the receiving wire 6 in a tensioned state, and is an optional component that can be omitted depending on convenience. FIG. 4 is a schematic diagram for explaining the principle of the present invention. As can be seen from this figure, the hinge shaft 3' is located above the receiving actuating electric wire 6, so when lifting the front pressure plate 1 , the receiving actuating electric wire 6 is l2 − l1 )
It will be pulled only. When the receiving actuating electric wire 6 is pulled by (l 2 - l 1 ), the upper end of the receiving member mounting bracket 10 is pulled to the left in the same figure, so it moves counterclockwise around the receiving member bracket axis 11. Rotate. Therefore, a receiving member 9 made of an elastic material attached to the lower surface of the bracket 10 is pressed against the original on the original placing table 7 to prevent the original from falling backward. Furthermore, when the pressure plate is closed, it returns to its original state by the action of the return spring 12.
