け得る値にした点にかかる原稿押えの支持構造である。In order to achieve the above-mentioned object, the main means adopted by the present invention is, as its gist, that a document placed on a document table movably arranged on the main body of a copying machine is placed on the upper surface of the document table. In the supporting structure of the document retainer to be fixed to the document retainer, an engaging portion made of an elastic body is formed at an end portion of the document table, and the engagement portion is cantilevered at the end portion of the document retainer. The joint portion is detachably fitted from the axial direction of the joint portion and engaged rotatably, and further, the document retainer is swung around the end portion of the document table or the document retainer about the engaged portion. An abutting portion that is capable of contacting the document retainer or the edge of the document table when closed and that is separated from the document retainer or the edge of the document table when swinging the document retainer to open and remove from the document table. Set the width of the relevant contact part so that the engagement part is positioned when the document retainer is closed. The point is set so that the end of the document retainer is biased toward the end of the document table and the document retainer is elastically stretched horizontally at the corresponding contact portion with the document table so that it can be fixedly attached. This is a support structure for the document pressing member.
原稿押えを閉じると、原稿押えの端部が上記当接部を介

値よりも僅かに大きな値に設定されている。Further, the end of the document retainer 14 can come into contact with the end of the document holder 10 when the document retainer 14 is closed, and when the document retainer 14 is swung and removed from the document holder 10. The manuscript table 10
An abutting portion 17 that is separated from the end portion of is integrally formed. The width L 1 of the abutting portion 17 is the distance L 2 from the end of the document table 10 to the axis of the engaging portion 11 in FIG. It is set to a value slightly larger than the value obtained by adding the distance L 3 to the shaft center.
従って、原稿押え14が原稿台10に対して閉鎖された時

付けられる。Therefore, when the document retainer 14 is closed with respect to the document table 10 (see FIG. 1D), the axial center position of the engaging portion 11 is elastically moved in the arrow 13 direction. As a result, the end of the document retainer 14 is elastically biased toward the end of the document table 10 (in the direction of arrow 12), and the document retainer 14 is elastically urged against the document table 10 by the contact portion 17. And fixed in the horizontal direction.
この場合、上記原稿台10の係合部11,原稿押え14のピン1

う不具合も生じない。As described above, the present invention provides a support structure for a document retainer for fixing a document placed on a document table movably arranged on the main body of a copying machine to the upper surface of the document table, in which the document table is supported. An engaging portion made of an elastic body is formed at the end portion, and an engaged portion formed in a cantilever shape at the end portion of the document retainer is detachably fitted in the engaging portion in the axial direction. It is rotatably engaged, and further, at the end of the document table or document retainer,
When the document retainer is swung about the engaged portion and closed, the document retainer or the end of the document table can be contacted, and the document retainer is swung to open and removed from the document table. An abutting portion is provided which is separated from the document holder or the end of the document holder, and the width dimension of the contact portion is adjusted such that the engaging portion is displaced when the document holder is closed so that the end of the document holder is moved to the original holder. Since the document retainer support structure is characterized in that the document retainer is urged toward the end portion and the document retainer is elastically stretched horizontally at the corresponding contact portion in a horizontal direction with respect to the document holder so as to be fixedly attached. The document retainer can be easily attached to and detached from the document table. Further, since the document retainer does not shake with respect to the document table during the copying process, the problem that the copied image is displaced does not occur.
