Abstract
A device incorporated in image forming equipment for transporting a paper sheet fed from any one of a plurality of vertically spaced paper feeding sections along a vertically extending common transport path. The common transport path is defined by an endless dielectric belt whose volume resistivity is selected to be 10.sup.8 to 10.sup.13 .OMEGA..multidot.cm. The belt transports a paper sheet upward while attracting it electrostatically thereon. A charging section implemented with a corona discharger and a counter electrode that face each other with the intermediary of the belt is located at each position where a path extending out from a particular paper feeding section merges into the common transport path.
Claims6
A device incorporated in image forming equipment for transporting vertically a paper sheet fed from any one of a plurality of paper feeding sections which are arranged one above another, said device comprising:
- an endless dielectric belt defining a common transport path for transporting vertically paper sheets which are selectively fed from said plurality of paper feeding sections;
- a plurality of charging sections disposed for charging said belt at positions where paper sheets fed from respective ones of said paper feeding sections are guided onto said common transport path;
- wherein each of said charging sections comprises a corona discharger and a counter electrode facing each other, with said belt being between the corona discharger and the counter electrode;
- and
- further comprising a plurality of grounding means each connecting said belt to ground at a position intermediate two adjacent ones of said charging sections.
