Abstract

Abstract A drive unit for a document feeding machine having: a paper feeding module having a pair of support railings; and a modular drive unit. The drive unit includes: a shaft journaled in the support railings; a conveying belt mounted on the shaft for conveying documents from an upstream position to a downstream position, the upper reach of said belt defining a feed path; a cross bar extending between and removably secured to the pair of support railings; a drive unit support plate secured to the cross bar; and a motor for driving the conveying belt secured to the support plate. When the cross bar is detached from the pair of support railings, the drive unit support plate, the motor and one end of the conveying belt drop below the feed path to facilitate repair of the modular drive unit.
