Abstract

PURPOSE:To maintain pressure of a pair of register rollers almost constant even when a size of a paper changes, by bringing the ends of thee rollers into cotact with the paper with a constant pressure in the side of a standard position, but with a different pressure in the other side. CONSTITUTION:Different sizes of transfer papers 24 are fed along the fixd position O on the one-side ends of register rollers 16(c), 16(d) as a standard. These rollers are pressed with a fixed pressure in the side of the standard position O, but applied pressure is variable into 4 steps on the other side. Width of the paper 24 fed is read with a paper width reader 163, this width signal is sent to a rotation angle controlling circuit 162, a rotary shaft 16(w) is turned by a given angle in accordance with the paper width with a motor 161, and a pressure of the rollers 16(c), 16(d) is maintained almost constant at both the ends of the paper 24.
