ABSTRACT:
A sheet receptacle is provided which is capable of carrying a multiplicity of sheets to be separated and conveyed, in theform of a stack. A suction device which shaped like an inverted cup is located above the receptacle and is supported by an associated support member. A piping connects the suction device with an air suction source, which may be operated to apply an air suction. The sucker support member forms part of a mechanism which imparts a rotary motion to the suction device, which is also associated with another mechanism which causes a movement of the suction device in the vertical direction as well as in the fore-and-aft direction. An air intake opening may be formed in the air flow path which connects the suction device with the air suction source, and is provided with a sheet receiver which can be covered by a sheet to be separated and conveyed or a sheet which is equivalent thereto.
