本発明は原稿給紙台に関し、特に原稿サイズに合わせて
、ＪＭ稿給紙台の幅及び長さを調節するのに好適な原稿
給紙台に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a document feeder, and in particular to a document feeder suitable for adjusting the width and length of a JM document feeder depending on the document size. Regarding the stand.
従来の装置は、実開昭５６−８３１６５号に記載のよう
に、原稿サイズ幅に合わせて一対の原稿ガイドが共動動
作するだけの機構になっていた。The conventional apparatus, as described in Japanese Utility Model Application No. 56-83165, has a mechanism in which a pair of document guides operate together in accordance with the width of the document size.
又、これに加えて原稿の長さ方向に伸縮する補助給紙台
を備えたものもあるが、原稿の幅方向のガイドとは連動
せず、調節を別々に行う必要があった。In addition to this, some devices are equipped with an auxiliary paper feed table that expands and contracts in the length direction of the document, but it does not work in conjunction with the guide in the width direction of the document, and the adjustment must be made separately.

た。また、長さ方向の調節として補助給紙台を設けたも
のにおいても、原稿給紙台の調節は、原稿ガイドの調節
及び補助給紙台の調節の合計２回行う事が必要である問
題があった。In the above-mentioned prior art, no particular consideration was given to adjusting not only the document width but also the length of the paper feed table for long documents. Furthermore, even in the case where an auxiliary paper feed tray is provided for adjustment in the length direction, there is a problem in that adjusting the document feed tray requires a total of two adjustments: adjustment of the document guide and adjustment of the auxiliary paper feed tray. there were.
本発明の目的は、原稿幅だけでなく原稿の長さ方向につ

稿給紙台を供給することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a document feed table that allows adjustment of not only the width of the document but also the length of the document in a single adjustment.
上記目的は、一対の原稿ガイドを共動動作させるピニオ
ンを２段に構成し、補助給紙台に設けられたラック部を
ピニオンに結合する事により達成される。The above object is achieved by configuring two stages of pinions for cooperating the pair of document guides, and by coupling a rack section provided on the auxiliary paper feed table to the pinions.
一対の原稿ガイド板は、ピニオンにより共動動作する。 The pair of document guide plates are moved together by a pinion.
ピニオンは２段で構成させているので、原稿ガイド板の
共動動作に使用しない他殺のピニオンを、補助給紙板に
設けたラック部に結合する事ができる。それによって、
補助給紙台は、原稿ガイド板の共動動作に連動する事が
でき、原稿大きさに合わせた°、原稿給紙台の調節が一
回で行なう事ができる。Since the pinion is constructed in two stages, the additional pinion that is not used for the co-operation of the document guide plate can be connected to the rack section provided on the auxiliary paper feed plate. Thereby,
The auxiliary paper feed table can be linked with the cooperative operation of the document guide plate, and the document feed table can be adjusted in one go according to the size of the document.
以下本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第１図は本発明の一実施例の斜視図である。図において
一対の原稿ガイド２が給紙台３の中心に対し左右対称に

に、引出し収納可能に給紙台３に設けられている。FIG. 1 is a perspective view of an embodiment of the present invention. In the figure, a pair of document guides 2 are provided symmetrically with respect to the center of a paper feed tray 3. The auxiliary paper feed tray 1 is provided on the paper feed tray 3 in a direction opposite to the document feeding direction so that it can be pulled out and stored.
第２図は一対の原稿ガイド２間が最も狭く、かつ補助給

。FIG. 2 shows a state in which the distance between the pair of document guides 2 is the narrowest and the auxiliary paper feed tray 1 is moving the most in the paper feeding direction.
第３図は本発明の一実施例のうち給紙台を除いた機構部
の正面図、第４図はその側面図を示す。FIG. 3 is a front view of a mechanical section of an embodiment of the present invention excluding the paper feed tray, and FIG. 4 is a side view thereof.
第３図及び第４図において、一対の原稿ガイド２には、
それぞれラック部材７が固着されており。In FIGS. 3 and 4, the pair of document guides 2 include

材６は、給紙方向に設けられ、上記ピニオン第一段５に
一体成形されたピニオン第２段４に契合されている。A first stage pinion 5 engages the pair of document guides 2 at their central positions. A rack member 6 provided on the auxiliary paper feed table 1 is provided in the paper feeding direction and engaged with a second pinion stage 4 integrally molded with the first stage pinion 5.

に移動する。The diagram of the embodiment shown in Fig. 1.3.4 shows a state in which the space between the pair of document guides 2 is widest and the auxiliary paper feed table 1 is moved the most in the opposite direction to the paper feeding direction. It shows. If one document guide 2 is moved toward the center of the pair of document guides, one rack member 7 will move, causing the first stage pinion 5 to rotate once, and the other rack member will move toward the center. The other document guide moves toward the center. At this time, due to the rotation of the first stage pinion 5, the second stage pinion 4 also rotates in the same direction, and the rack member 6 provided on the auxiliary paper feed table 1 moves in the paper feeding direction. moves in the paper feeding direction.
補助給紙台１を給紙方向に移動した場合も、上記連動機
構が作動し、原稿ガイド２が中心方向に移動する。When the auxiliary paper feed table 1 is moved in the paper feeding direction, the above-mentioned interlocking mechanism is activated and the document guide 2 is moved toward the center.
又、第２図の実施例のように原稿ガイド間が最も狭く、

置から離れる方向に移動する。Also, as in the embodiment shown in Fig. 2, the distance between the document guides is the narrowest,
If the auxiliary paper feed tray 1 is in the state where it is moving the most in the paper feeding direction, move the pair of document guides 2 away from the center position, or move the auxiliary paper feed tray 1 in the opposite direction to the paper feeding direction. By moving, the first stage of the pinion 5. Pinion 2nd
Since the rotation direction of the stage 4 is reversed, the auxiliary paper feed tray 1 moves in the opposite direction to the paper feeding direction, or the pair of document guides moves in a direction away from the center position.
本実施例によれば、補助給紙台１及び原稿ガイド２のど
ちらか一方を動作させれば他方が共動動作し、原稿の幅
