This paper describes basic study on sheet attitude during decelerated delivery of the nip transport mechanism. The nip transport mechanism with a pair of rollers is widely used in many devices, such as automated teller machines (ATMs), printing machines, etc. In these machines, a sheet is sometimes nipped by two pairs of rollers rotating at unequal speeds. There are two kinds of the conveyance between rollers with unequal speeds, namely, accelerated delivery and decelerated delivery. The sheet attitude during the accelerated delivery and the decelerated delivery can be changed. In this paper, we analyzed the sheet attitude during the decelerated delivery by the geometric modeling and experimental observation. As a result, we have clarified that there are two modes of the sheet behavior during the decelerated delivery and we have found the parameters that affect the sheet attitude.
