Abstract: A sheet depositing device for a sheet processing apparatus, includes a feeding section for sequentially feeding sheets or sets of sheets from the sheet processing apparatus, at least one sheet stacking element movable along a guide, for facilitating depositing the sheets or sets of sheets fed by the feeding section, and a sensor arrangement for detecting the position of a sheet stacking element along the guide. The sensor arrangement includes a stationary linear array of active elements and a passive element moving in unison with the sheet stacking element. The active and passive elements are of a kind that interact through the use of electric or magnetic fields. Examples of such sensors are an array of conductive fields arranged in parallel to a conductive strip or a second array of conductive fields, and a conductive plate connected to a capacitance meter; and an array of Hall-effect sensors and a magnet.

Abstract: A sheet depositing device for depositing sheets or sets of sheets fed sequentially from a paper processing apparatus onto a depositing platform and against a depositing registration barrier, the sheet depositing device including a sheet catcher adapted to rest on said depositing platform or adapted to rest on sheets stacked on the depositing platform, the sheet catcher being movable in a direction substantially perpendicular to the depositing platform and engaging the leading edge of incoming sheets before they abut with the depositing registration barrier, and further containing a sheet engaging member suspended from the sheet catcher.
