同図(a)に示すように原稿lが斜めに挿入されると、
円錐状ローラ7と原稿1との接触点Bでは周速はbであ
り、接触点Cでは周速Cである。When the original l is inserted diagonally as shown in Figure (a),
At the contact point B between the conical roller 7 and the document 1, the peripheral speed is b, and at the contact point C, the peripheral speed is C.
従って、周速b>cである為に原稿1は円錐状ローラ7
の仮想中心りを中心にして矢印E方向に回動を開始する
。Therefore, since the circumferential speed b>c, the document 1 is transferred to the conical roller 7.
It starts rotating in the direction of arrow E about the virtual center of .
原稿1が回動して同図(b)の如き状態になると、左側
の円錐状ローラ7゛ も同図(a)と同様に仮想中心F
を中心に原稿1を矢印G方向に回動しようとする。When the document 1 rotates and reaches the state shown in FIG. 2(b), the left conical roller 7' also moves to the virtual center F as in FIG.
The document 1 is attempted to be rotated in the direction of arrow G around .
然し乍ら、原稿1と円錐状ローラ7及び7゛の接触長さ
矢印7!、とlLは2.>4.であるから、原稿lは仮
想中心りを中心にして矢印E方向に回動する。However, the contact length between the original 1 and the conical rollers 7 and 7'' is 7! , and LL are 2. >4. Therefore, the original l rotates in the direction of arrow E around the virtual center.
そして、原稿1が同図(C)に示すように接触長さ矢印
IRとlLが等しくなると、円錐状ローラ7及び7”の
搬送力は釣り合い原稿1はこの侭の状態で送りローラ3

move in the direction of
移動した原稿1は同図(diに示すように原稿1の突出
した端部1aが停止している送りローラ3に突当たる。The moved original 1 hits the stationary feed roller 3 with its protruding end 1a, as shown in FIG.
この状態で更に円錐状ローラ7及び7゛を回転すると、
原稿1は送りローラ3と突当たった点Hを中心に矢印M
のモーメントを受け、同図(めに不す如くその端部を均
一に送りローラ3に突当てる。In this state, when the conical rollers 7 and 7 are further rotated,
The document 1 moves in the direction of the arrow M centered on the point H where it collides with the feed roller 3.
As shown in the same figure, the end uniformly hits the feed roller 3 as shown in the figure.
この突当った状態は両端のセンサ8に依って検出され、
検出と同時に従来のモータ12aと共にモータ12bを
駆動して、円錐状ローラ7及び7゛ と送りローラ3と
