Description
【発明の詳細な説明】 ト位置合せ装置に関する。[Detailed description of the invention] This invention relates to an alignment device.
周知のように、両面複写型複写機においては、片面に複
写された記録紙(シート)を再び複写機の給紙部に送込
んで、反転した記録紙の裏面に複写を行うが、この両面
コピーの際には、片面複写済のシートを規定の位置に正
確に位置決めした後、再給紙する必要がある。As is well known, in a double-sided copying machine, the recording paper (sheet) that has been copied on one side is fed into the paper feed section of the copying machine again, and the copy is made on the reverse side of the recording paper that has been reversed. When copying, it is necessary to accurately position a single-sided copy sheet at a specified position and then re-feed the sheet.
このため、従来では、搬送シートの受台の両側に定規板

うな構造では、シートの幅方向の位置は正確であっても
、シートの移動方向の位置が不正確になるので、裏面複
写iIIii像の位置がづれ、両面複写の価値が損われ
ている。For this reason, conventionally, it has been proposed to refeed paper by placing ruler plates on both sides of the pedestal of the conveyed sheet, but with this structure, even if the position of the sheet in the width direction is accurate, Since the position in the moving direction of the sheet becomes inaccurate, the position of the reverse side copy image is shifted, and the value of double-sided copying is lost.

するものである。In view of the actual situation of the conventional sheet positioning device as described above, the present invention provides a pair of ruler plates that are movable in a direction perpendicular to the direction of movement of the sheet on both sides of a pedestal that is inclined in the direction of movement of the sheet. A blocking plate is positioned in front of the cradle and tilted in a horizontal plane with respect to the moving direction, and the sheet tilted and blocked by the blocking plate is brought to a specified position by movement of a ruler plate. This is a proposal.
以下、図面について本発明の実施例の詳細部説明する。Hereinafter, details of embodiments of the present invention will be explained with reference to the drawings.

で送られる。The illustrated embodiment is an embodiment in which the sheet alignment device of the present invention is installed in a paper refeeding device 1 of a double-sided copying machine, and the double-sided copying machine has an exposure optical device that optically scans a document a. It has a photosensitive drum 2 housed in the lower part, and around the photosensitive drum 2, a charging electrode 8, a phenomenon device 4, a transfer separation electrode 5, and a cleaning device #6 are arranged. The recording paper is transferred from the paper feed cassette 8 to the paper feed roller 9 by a feeding roller ruff.
The recording paper sheet with the toner image transferred thereto is sent to a conveyance device 10, a heating roller fixing device 11, and a paper ejection roller device 12. In the case of double-sided copying, the recording paper sheet is re-fed from the paper ejection roller device 12. It is sent to the paper device 1. Then, after the recording sheet to be double-sided copied is aligned in the paper refeeding device l as described below, it is placed in the path between the feeding roller 7 and the paper feeding roller 9 by the action of the paper refeeding roller 18. Sent inverted.

。2 to 4 show details of the sheet refeeding device #1, that is, the sheet alignment device of the present invention, and the sheet refeeding device #l is a cradle whose width is narrower than the width of the recording sheet to be moved in the direction of the arrow X. 14, and this pedestal 14 is normally placed in a state where it is tilted down in the moving direction XK of the recording paper as shown in the second figure, and this pedestal 14 is provided with a support shaft 15 as a fulcrum after alignment. As shown in FIG.
また、受台14の両側には移動方向Xに対して直角な方
向に移動できる一対の定規板16A 、 16Bが位置
しである。即ち、これらの定規板16A。Furthermore, a pair of ruler plates 16A and 16B that can be moved in a direction perpendicular to the moving direction X are located on both sides of the pedestal 14. That is, these ruler plates 16A.

角度θだけ傾けられた衝止面20を有している。16B is a device that can be moved in the direction of arrow Y along the elongated hole ]8 inserted into the guide pin 17 of the device fixing part, and the moving direction X
Each has a ruler surface 16a parallel to the . and,
The paper refeeding device 18 according to the present invention has a blocking plate 19 located in front of the pedestal 14, and the blocking plate 19 for receiving the fed recording paper is arranged in a horizontal plane with respect to the moving direction X. It has a blocking surface 20 inclined by an angle θ.
前記実施例における再給紙装置1は、以上のような構造

距離を記録紙すの幅寸法に一致させた状態では、記録紙
すの水平面内での位置は予め定めた規定の位置となる。Since the paper refeeding device 1 in the embodiment has the above structure, the recording paper placed on the pedestal 14 is
4 is descending diagonally, it slides to the right along the pedestal 14, and is stopped by the stopping surface 20 as shown in the virtual drill in FIG. 3. After this, the ruler plates 16A, 16 are spaced apart.
When B are moved closer to each other, the corner C of the recording paper is aligned with the ruler surface 1.
6a, the sheet of paper No. 9 is rotated in a horizontal plane around its center, and its rotation angle and the position of its right edge are automatically corrected by the stop surface 20 and the ruler surface 16F1. As a result, when the distance between the ruler surfaces 16a is made to match the width of the recording paper tray as shown in FIG. 4, the position of the recording paper tray in the horizontal plane becomes a predetermined position.
