【考案の詳細な説明】 産業上の利用分野 本考案はファクシミリ装置等の印字装置に用いられる給
紙装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a sheet feeding device used in a printing device such as a facsimile device.
従来の技術 従来、ファクシミリ装置等においてセットした原稿を一
枚ずつ分離、搬送する給紙装置が広く利用されている。2. Description of the Related Art Conventionally, a sheet feeding device that separates and conveys set originals one by one in a facsimile device or the like has been widely used.
以下従来の給紙装置の構成について説明する。第２図は

稿で、８は原稿７を挿入する紙挿入口である。The configuration of a conventional paper feeding device will be described below. FIG. 2 is a cross-sectional view of a main part of a conventional sheet feeding device. 1 is a document feeding roller, 2 is a separation plate that is in pressure contact with the roller 1 to separate and convey documents, and 3 is a separation plate 2 in the direction of the roller 1. Leaf spring that urges to
Reference numeral 4 denotes a leaf spring which is pressed against the roller 1 to hold and convey the original.
Is a document placing plate, 6 is a cabinet, 7 is a set document, and 8 is a paper insertion port for inserting the document 7.
以上のように構成された給紙装置について、以下その動
作を説明する。The operation of the sheet feeding device configured as described above will be described below.
オペレータは原稿を原稿挿入口８より原稿載置板５に沿

番上の原稿7aから順番に一枚ずつ分離しながら搬送して
いく。The operator sets a document from the document insertion port 8 along the document placing plate 5, and when the document is set, in the case of a facsimile machine, the transmission button or the copy button is pressed to perform a transmission operation or a copying operation. As shown in FIG. 2, the paper feeding device sequentially conveys the original document 7a while separating it one by one in accordance with the rotation of the document feed roller 1.
考案が解決しようとする問題点 しかしながら、上記従来の構成では第３図に示すように
オペレータが原稿をセットする場合に原稿を必要以上に
強く分離板方向に押し入れると板バネ３がたわみ、原稿

原稿を分離板２に当てると分離板２は多少たわむため、
少し強く原稿を押しこむと原稿は所定の位置より奥には
いってしまうという問題点も有していた。However, in the above-described conventional configuration, when the operator sets the original document as shown in FIG. 3, if the original document is pushed in the direction of the separating plate more than necessary, the plate spring 3 is bent, and the original document is bent. A plurality of originals are inserted between the feed roller 1 and the separation plate 2. If the sending operation and the copying operation are performed in this state, the originals are not normally separated, and there is a problem that two or three originals are sent together. In addition, the original must be inserted to a position where the leading edge of the original comes exactly where the original feeding roller 1 and the separating plate 2 are in contact with each other.
When a document is applied to the separating plate 2, the separating plate 2 bends a little, so
There is also a problem that if the document is pushed a little strongly, the document will go deeper than a predetermined position.
問題点を解決するための手段 本考案は、上記問題点を解決するため原稿をセットする
場合に原稿が原稿送りローラに最初に突き当たり、かつ
板バネにも分離板にも押し当たらないように、保持用板
バネの高さよりも高く原稿案内部材を形成して設けたも
のである。Means for Solving the Problems The present invention, in order to solve the above problems, when the original is set, the original does not hit the original feeding roller first and does not press against the leaf spring or the separating plate. The document guide member is formed to be higher than the height of the holding leaf spring.
作用 本考案は上記構成の通り、原稿案内部材を備えたことに
より、オペレータが原稿をセットする場合、原稿は原稿
送りローラに突き当たり、板バネにも分離板にも押し当
たらないように案内される。As described above, the present invention is provided with the document guide member, so that when the operator sets the document, the document is guided so as not to hit the document feed roller and not to hit the leaf spring or the separation plate. .
従って、オペレータは用紙が原稿ローラに突き当たった
ことを容易にかつ正確に認識することができる。そのた
め無理に原稿を押し込むことが無くなり、重送を防止す
るために必要な適切な原稿の装着が容易に実現される。Therefore, the operator can easily and accurately recognize that the sheet has hit the document roller. Therefore, it is not necessary to force the document to be pushed, and it is possible to easily mount an appropriate document necessary to prevent double feeding.

枚ずつ確実に分離、搬送される。The operator inserts a document from the document insertion port 8 along the document placing plate 5. Since the document guide member 9 supports the document 7 without being bent or distorted, the inserted document 7 advances along the slope of the document guide member 9 and strikes the side surface of the document feed roller 1. Here, the operator confirms the position where the document 7 hits the document feed roller 1 by the feel of the hand, and holds the document 7 at this position. The abutting position is the holding leaf spring 4 and the separation plate 2 with respect to the rotation direction of the document feed roller 1 (counterclockwise direction in FIG. 1).
It is located on the upstream side. In this state, a document detection sensor (not shown in the drawing) detects that the document 7 is set, and the document feed roller 1 rotates. When the document feeding roller 1 starts to rotate, the operator releases the document 7 from his hand. Since the edge of the document 7 is in contact with the surface of the document feed roller 1, when the document feed roller 1 rotates, the document 7 moves with respect to the rotation surface of the document feed roller 1. Therefore, all the originals 7 inserted by the rotation of the original feed roller 1 are fed until they hit the separation plate 2. The force with which the document 7 is fed is determined by the coefficient of friction between the document 7 and the surface of the document feed roller 1. Therefore, the material of the surface of the document feed roller 1 is appropriately selected and the friction coefficient of the surface of the document feed roller 1 is set appropriately. Then, the original 7 is pressed against the separating plate 2 with an appropriate force. Therefore, the originals 7 are reliably separated and conveyed one by one by the original feeding roller 1.

搬送することができる。As described above, according to the present invention, when a document is set, the document guide member is provided to guide the document so that the document does not hit the document feed roller and press against the separation plate. In this case, the operator can clearly know the position where the document hits the roller, so the operator can easily insert it in the correct position.Because the separation plate does not deform when inserting the document, the documents are separated one by one with certainty. ,
Can be transported.
