    • A range sensor includes a charge generating region, a signal charge collecting region, an unnecessary charge collecting region, a photogate electrode, a transfer electrode, and an unnecessary charge collecting gate electrode. Outer peripheries of the charge generating region extend to sides of a polygonal pixel region except for corner portions thereof. The signal charge collecting region is disposed at a center portion of the pixel region and inside the charge generating region so as to be surrounded by the charge generating region. The unnecessary charge collecting region is disposed in the corner portion of the pixel region and outside the charge generating region. The photogate electrode is disposed on the charge generating region. The transfer electrode is disposed between the signal charge collecting region and the charge generating region. The unnecessary charge collecting gate electrode is disposed between the unnecessary charge collecting region and the charge generating region.

    • A sheet conveyer, including a manual-feed conveyer path; a first sensor to detect presence of the sheet inserted in the manual-feed conveyer path; an upstream-side conveyer and a downstream-side conveyer to convey the sheet toward a downstream side; a second sensor to detect presence of the sheet in a downstream position with respect to the upstream-side conveyer, the second sensor being switchable between a presence-detectable state and an absence-detectable state; and a controller is provided. The controller measures presence-detecting duration of the sheet by the second sensor and controls the downstream-side conveyer to continue conveying the sheet if the first sensor is detecting presence of the sheet when the second sensor is switched to the absence-detectable state, and if a difference between a value calculated based on the measured presence-detecting duration and a reference value obtained based on a reference sheet length is smaller than a predetermined threshold.
