Abstract:
A sheet feeder includes a roller, a reflector, a sensor, and a rotating speed detector. The reflector is integrally attached to the roller, the reflector including first reflecting surfaces and second reflecting surfaces arranged alternately along a circumference direction of the roller. The sensor includes a light emitter and a light receiver. The rotating speed detector is configured to detect a rotating speed of the roller based on a result of the detection by the sensor. Each of the first reflecting surfaces reflects the inspection light at a first reflection ratio, and provides a first reflection light path along which the inspection light is directed to the light receiver. Each of the second reflecting surfaces reflects the inspection light at a second reflection ratio smaller than the first reflection ratio, and provides a second reflection light path along which the inspection light is directed outside the light receiver.

Claim (Index 2):
The sheet feeder according to  claim 1 , further comprising:\n a roller attaching portion to which the roller is attached, wherein in a state that the roller is attached to the roller attaching portion, the roller shaft is inclinable in a predetermined range with respect to a standard attachment direction defined in advance, each of the first reflecting surfaces provides the first reflection light path with the roller inclined in the predetermined range, and each of the second reflecting surfaces provides the second reflection light path with the roller inclined in the predetermined range.
