(57) [Summary] [Purpose] To provide an automatic paper feed mechanism for reducing the device size by installing a printing mechanism, a reading mechanism, etc. within a paper size range. [Structure] A roller 1 for moving a sheet 6, a pressing plate 4 and a pressing mechanism 5 for pressing the sheet 6 against the roller 1, a guide iterator 2 arranged so as to contact the upper surface of the sheet within a range of the sheet size, and a sheet. A cassette 3 for storing is provided.
Description
【０００１】[0001]
本考案は、自動給紙機構に関し、特に定形紙を一枚一枚分離し給紙する自動給 紙機構に関する。 The present invention relates to an automatic paper feed mechanism, and more particularly to an automatic paper feed mechanism that separates and feeds standard paper one by one.
【０００２】[0002]
従来の自動給紙機構は、図３に示すように、用紙走行方向前方の端につめのつ いた用紙積載のためのカセット７を使用する。ローラ１を矢印方向に回転させる ことで、ローラ１に圧接された用紙６のうち最上位の一枚がカセット７のつめを のりこえ走行され、一枚ずつ分離給紙していた。 As shown in FIG. 3, the conventional automatic sheet feeding mechanism uses a cassette 7 for loading sheets, which is provided at the front end in the sheet traveling direction. By rotating the roller 1 in the direction of the arrow, the uppermost one of the sheets of paper 6 pressed against the roller 1 has run over the pawls of the cassette 7 and separated and fed one by one.
【０００３】[0003]
従来の自動給紙機構は、図３に示すとおり、カセット７の端にあるつめに用紙 ６を引っかけることにより、用紙６のうち一枚だけ分離し走行させる構造のため 、カセット７の用紙走行方向前方に印字機構や読取機構等８を設置しなければな らず、装置のサイズが大きくなるという欠点があった。 As shown in FIG. 3, the conventional automatic paper feeding mechanism has a structure in which one of the papers 6 is separated by running by hooking the paper 6 on the claw at the end of the cassette 7, so that the paper running direction of the cassette 7 is changed. Since the printing mechanism, the reading mechanism, and the like 8 must be installed in the front, the size of the device is large.
【０００４】 本考案の目的は印字機構、読取機構などを用紙サイズ範囲内に設置し、装置サ イズを小さくさせる自動給紙機構を提供することにある。An object of the present invention is to provide an automatic paper feed mechanism that reduces the apparatus size by installing a printing mechanism, a reading mechanism, etc. within a paper size range.
【０００５】[0005]
本考案の自動給紙機構は、複数枚積載した用紙を収納するカセットと積載した 用紙のうち最上位のものから順次送るためのローラと、ローラに用紙を圧接させ るための手段とを備え、かつ最上位の用紙に常時圧接しているガイドイタをロー ラより用紙走行方向の前方に配置することよりなる。 The automatic paper feeding mechanism of the present invention comprises a cassette for storing a plurality of stacked sheets of paper, a roller for sequentially feeding the topmost stacked sheets of paper, and a means for pressing the sheets against the rollers. In addition, the guide iter, which is always in pressure contact with the uppermost sheet, is arranged in front of the roller in the sheet traveling direction.
【０００６】[0006]
まず、用紙が走行方向と逆方向に走行するようにローラを回転させて、ローラ 側最上位の一枚だけ他の用紙から分離させ、次いでローラを逆回転させて分離し た用紙一枚を走行方向前方に走行させて、用紙上面に圧接するように配置された ガイドイタに導きいれ、用紙サイズ範囲内で他機構へ給紙する。 First, rotate the roller so that the paper runs in the direction opposite to the running direction, and separate only the uppermost sheet on the roller side from the other paper, and then rotate the roller in the reverse direction to run the separated sheet. In the direction of the paper, the paper is guided to a guide iter that is pressed against the upper surface of the paper, and the paper is fed to another mechanism within the paper size range.

次に本考案について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.

【０００９】 押圧板４は、上下方向に揺動し、押圧機構５（図では、コイルバネ）の押圧力 により用紙６をローラ１に押しつけている。先ず、図２−Ａに示すように、ロー ラ１がａ方向に回転することで、用紙６は図の右方向へ走行し他の用紙からロー ラ側の一枚だけ分離する。用紙の端面イがガイドイタ２の右側にくるまでローラ １はａ方向に回転する。次いで図２−Ｂに示したように、ローラ１はｂ方向に回 転し、用紙を図左方向へ走行させ、用紙上面に配置されたガイドイタ２へ導き、 用紙サイズ範囲内で他機構へ用紙を送る。The pressing plate 4 swings in the vertical direction and presses the sheet 6 against the roller 1 by the pressing force of the pressing mechanism 5 (coil spring in the figure). First, as shown in FIG. 2-A, when the roller 1 rotates in the direction a, the sheet 6 runs to the right in the figure and separates only one sheet on the roller side from other sheets. The roller 1 rotates in the direction a until the end face a of the sheet comes to the right side of the guide iter 2. Next, as shown in FIG. 2-B, the roller 1 rotates in the b direction, runs the paper in the left direction of the drawing, guides it to the guide iterator 2 arranged on the upper surface of the paper, and transfers it to another mechanism within the paper size range. To send.
