ABSTRACT:
An automatic sheet stack loading mechanism of a paper sheet feeding apparatus has a main lift for supporting a stack of sheets to be fed thereon. The main lift is incrementally moved upwardly to place the uppermost sheet of the stack at a predetermined height position with respect to a sheet separator disposed over the stack and operating to separate the sheets one by one from the stack. When the stack of sheets is consumed considerably, parallel horizontal spits are inserted under the stack from both transverse sides of the stack thereby to support the load of the stack and to enable the main lift to be lowered to receive a new stack of the sheets. The insertion of the spits in the transverse direction of the stack is advantageous in that the central portion of the sheets of the stack along the direction of feed of the sheets is maintained at constant height irrespective of downward deflection of the spits so that adjustment in position of the sheet separator is not required.
