An endless conveyer belt is stretched between drive and idle rollers. A carriage is arranged so as to reciprocate along the endless conveyer belt. A suction box is arranged between upper and lower belt portions of the endless conveyer belt and fixed to the carriage. A stopper plate is fixed to the carriage and extends across a conveyer surface and upward from the conveyer surface. A conveyance roller pair is arranged at the upstream end of the conveyer surface. A region of the conveyer surface from a stopper plate to the upstream end u forms a sheet accumulation area. A cover sheet covers a region upstream of the suction box in the sheet accumulation area. The cover sheet is subjected to tension in the longitudinal direction by a winding-type constant force plate spring and continually tensed spaced apart from the endless conveyer belt.

Sheet conveyance apparatus

Perforated endless conveying belts are stretched between drive and idle rollers. A suction box is arranged between upper and lower belt portions of the perforated endless conveying belts. Abutment members are attached to positions of a support corresponding to the perforated endless conveying belts and pressed against the perforated endless conveying belts. The upstream of the suction box from the abutment members forms an attracting area, and intake holes are formed therein. Lifting plates extend to at least an intake hole range of the attracting area between the perforated endless conveying belts. The lifting plates move between a first position to vertically open the intake holes and project from conveying surfaces of the perforated endless conveying belts and a second position to close the intake holes and retract from the conveying surfaces of the perforated endless conveying belts.

Sheet feeding apparatus, control method of the same, and non-transitory computer storage medium storing control program of the same

A sheet conveyance apparatus includes a control unit () that controls driving of a belt drive mechanism (). The control unit () performs control such that the sheet is conveyed from the sheet accumulation area if (a) it is determined that the number of sheets currently accumulated in the sheet accumulation area is two or greater, while the sheet is not conveyed from the sheet accumulation area if (b) it is determined that the number of sheets currently accumulated in the sheet accumulation area is one.
