Abstract

Abstract Translated from Japanese (57)【要約】 【目的】コピー原稿に厚さや紙質等の性状が異なるもの が混在するとき、原稿の性状に忠実なシート材を自動的 に選択してこれに画像形成を行なう。 【構成】原稿給送装置Rに原稿Dの性状(例えば原稿D の厚さ)を1枚ずつ識別する識別手段26を配設し、装 置本体1に複数の給紙カセットK1、K2、K3を判別 する判別手段24を配設する。識別手段26からの信号 によって判別手段24を特定する、すなわち、原稿Dの 厚さの違いによって給紙カセットを特定する制御装置2 9を配置する。原稿D中に3種の厚さの原稿D1、D 2、D3が混在するときは、給紙カセットK1、K2、 K3にそれぞれ厚さの異なるシート材P1、P2、P3 を収納しておく。識別手段26が原稿D1を識別する と、制御手段29は、判別手段25を介して給紙カセッ トK1を選択する。つまり、原稿D1の厚さと同じ厚さ のシート材P1を選択する。これにより、原稿Dに忠実 なコピーを自動的に得ることができる。 (57) [Summary] [Purpose] When the originals to be copied have different properties such as thickness and paper quality, a sheet material faithful to the original characteristics is automatically selected and an image is formed on it. [Structure] The document feeding device R is provided with a property of the document D (for example, the document D The identification means 26 for identifying the sheet thickness of each sheet is provided one by one, and the identification means 24 for identifying the plurality of sheet feeding cassettes K1, K2, K3 is provided in the apparatus main body 1. The control device 2 for identifying the discriminating means 24 by the signal from the discriminating means 26, that is, for identifying the paper feed cassette by the difference in the thickness of the document D. Place 9 Documents D1 and D with three different thicknesses in document D When 2 and D3 are mixed, the sheet feeding cassettes K1, K2, Sheet materials P1, P2, P3 having different thicknesses for K3 To store. When the identification unit 26 identifies the original document D1, the control unit 29 selects the paper feed cassette K1 via the determination unit 25. That is, the sheet material P1 having the same thickness as the original D1 is selected. As a result, a copy faithful to the original D can be automatically obtained.
