摘要： There is provided a recording medium imaging device capable of properly selecting pixels used for determining the kind of the recording medium from the captured surface image to remove pixels from which the surface property of the recording medium cannot be properly determined because the pixels extremely high in light quantity are affected by some sort of dirt or scratches in determining the kind of a recording medium. This allows the determination of kind of the recording medium based on the normally captured surface image to reduce the decrease in accuracy in determining the kind of the recording medium.

摘要： A recording material determination device obtains a difference between a peak time, which is a first measurement result when an ultrasonic wave has passed through a recording material, and a peak time, which is a second or subsequent measurement result. The recording material determination device compares the difference with a double feed determination threshold value set based on the difference between the peak times, to precisely determine double feed of the recording materials without being influenced by an environment and the kind of the recording material.
