Abstract:
1. A sheet feeder device, comprising: a sheet accommodating section for accommodating a stack of sheets; a sheet pick-up section operative to feed each of the sheets toward a sheet feed path when abutting against the stack; and a sheet separating section having a feed roller and a reverse roller which are located downstream of the sheet pick-up section and biased to abut against each other, wherein: 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 shaft in an axial direction of the rotation support shaft; the rotation support shaft has opposite ends, which are rotatably supported by a device body via a respective first support and a respective second support; and the first support is selectively switchable between a first position in which the reverse roller is not removable from the rotation support shaft, and a second position in which the first support allows the reverse roller to move away from the feed roller and allows a first end of the rotation support shaft to be disengaged from the first support, the first support, located at one end of the rotation support shaft, having a first support member pivotally supported by the device body, and a second support member that is removable from the first support member and includes a shaft hole through which the rotation support shaft extends, the first support member being attached to a resilient member providing rotational tension on the first support member about its pivoting axis, the second support member being removable from the first support member while the resilient member maintains the tension on the first support member.
