<p>A sheet changer which cyclically changes the distribution of a pile of sheets comprises a housing and a drawer which can be slid out of the housing. The pile of sheets is compressed by a spring arrangement against a window arranged in the housing. When the drawer moves, the pressure causes excessive friction, which is reduced by friction-reducing elements arranged between the drawer and the housing or the compression arrangement at the points on which the force of the spring is exerted.</p> |
