Abstract: Промежуток между боковой направляющей и внешним лопастным колесом задается короче интервала в вертикальном направлении между выпускным отверстием и верхней поверхностью самой верхней банкноты, помещенной на платформу. Вследствие этой конфигурации, даже если один концевой участок в направлении ширины банкноты, расположенной между боковой направляющей и внешним лопастным колесом, деформирован так, чтобы сгибаться в сторону выпускного отверстия, один край банкноты может быть предотвращен от достижения высоты выпускного отверстия. В результате, ситуация, в которой один край банкноты сталкивается с последующей банкнотой, которая должна быть выпущена через выпускное отверстие, и вызывает замятие банкноты, может быть устранена. 2 н. и 9 з.п. ф-лы, 20 ил.
