Sheet reverse apparatus

摘要

A sheet reverse apparatus for reversing a paper sheet discharged from an image forming apparatus has a mounting mechanism fixed to the image forming apparatus, and a power transmission mechanism. The power transmission mechanism is engaged with an output gear coupled to a drive source of the image forming apparatus, and transmits a driving force from the image forming apparatus to an input gear. The power transmission mechanism has a swingable plate and a spring for biasing the swingable plate in one direction. A movable gear meshed with the input gear and rotatable therearound is axially supported on the swingable plate. When the sheet reverse apparatus is mounted on the image forming apparatus, driving power from the sheet reverse apparatus can be supplied from the image forming apparatus through the input gear and the power transmission mechanism.
