Abstract

PURPOSE:To improve synchronization of fed transfer paper, by forming non- forcible contact areas, having rollers of external diameter larger than external diameter of rollers in a forcible contact areas, in a conveyance area of synchronous rollers for a copying machine or the like. CONSTITUTION:Register rollers 2a, 2b are forcibly contacted in forcible contact areas A, to simultaneously form non-forcible contact areas B by toothed rollers 2a', 2b' of external diameter Dm larger than an external diameter D of the rollers in the forcible contact area. The toothed rollers 2a', 2b' are alternately arranged. In this constitution, transfer paper, reaching a forcible contact part of the register rollers 2a, 2b, is blocked by the toothed rollers 2a', 2b' and can not reach the forcible contact area A, and a normal loop is formed. Accordingly, the register roller can be prevented from biting the paper to cause a difference in a shift, and synchronization can be effectively obtained.
