【考案の詳細な説明】 〔産業上の利用分野〕 本考案は複写機の載設して使用される自動原稿
送り装置の改良に関するものである。
[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of an automatic document feeder installed in a copying machine.

〔従来の技術〕[Conventional technology]

複写機に付設して使用される自動原稿送り装置
は、大型化すると重量も重くなつて操作性が悪く
なり、また製品の価格も増大することもあつて、
一般に原稿給紙皿の大きさをA3判の原稿を載置
出来るサイズに限定されているのが普通である。
As automatic document feeders used with copying machines become larger, they become heavier and less operable, and the price of the product also increases.
Generally, the size of the document feed tray is usually limited to a size that can accommodate an A3 size document.

従つて、かかる自動原稿送り装置を使用して
A3判を超えるサイズ例えばA2判の原稿によつて
複写を行う場合には、原稿のほぼ2分の1の面積
が原稿給紙皿から垂れ下るので、搬送中に落下し
たり、あるいは皺や折れ目を生じて原稿自体を傷
める危険があり、また極端な場合ジヤムを起して
搬送不能となることもある。
Therefore, using such an automatic document feeder
When copying a document larger than A3 size, for example, A2 size, approximately one-half of the document will hang down from the document feed tray, so it may fall off during transport, or it may get wrinkled or folded. There is a risk that the document itself may be damaged due to scratches, and in extreme cases, it may jam and become unable to be conveyed.

そのため、このような場合作業者は原稿の端部

In addition, when copying such large-sized originals, if the copying machine has a switchable copying mode, in order to switch to exposure scanning by moving the original,
Operations such as fixing the exposure and imaging system of the copying machine in a fixed position and retracting the original stopper at the end of the original placing glass are required.

The present invention provides a rotatable auxiliary tray at the end of the document feed tray opposite to the conveyance direction of the automatic document feeder, and when conveying small documents, the auxiliary tray is stacked on the document feed tray. When transporting a large original by placing the original on the surface of the auxiliary tray,
When the auxiliary tray is opened, its back surface forms an inclined surface that connects with the document feed tray to receive the document, and a magnet attached to the auxiliary tray is detected by a magnetic sensor built in the automatic document feeder. It is configured to automatically switch the exposure scanning mode of the copying machine based on a signal, and is pivoted at the side end of the document feed tray, closes to overlap the document feed tray, and opens to overlap the document feed tray. In addition to providing an auxiliary tray serving as an extension of the document feed tray, a detection means for detecting the opening/closing position of the auxiliary tray is provided, and the exposure mode in the copying machine is switched in conjunction with the opening/closing operation of the auxiliary tray. This is achieved by an automatic document feeder having a characteristic copying machine auxiliary tray.
