Sheet feeder device, image reading apparatus and image forming apparatus

摘要

A sheet feeder device includes a sheet accommodating section for accommodating a stack of sheets. There is a sheet pick-up section which can operate to feed each of the sheets toward a sheet feed path when abutting against the stack. A sheet separating section is also provided and it has a feed roller and a reverse roller which are located downstream of the sheet pick-up section and abut against each other. The reverse roller is supported on a rotation support shaft in a manner to allow the reverse roller to be fitted around and removed from the rotation support. The rotation support has opposite ends supported by a device body.
