ABSTRACT:
An image sensing device includes: a light source, a recording member on which an image is formed and conveyed in one direction, illumination system for causing a light beam emitted from the light source to obliquely illuminate the recording member and, imaging system for condensing specularly reflected light from the image on the recording member and causing the reflected light to travel to a surface of a photodetector, so that the image sensing device obtains positional information of the image on the recording member on the basis of a signal obtained by the photodetector. When the amount of displacement of the recording member in a vertical direction during conveyance of the recording member is d, an angle between the optical axis of the imaging system and a normal to the recording member is θ (degrees), and resolution of the image formed on the recording member is R (dpi), the components are set so thatin-line-formulae description="In-line Formulae" end="lead"?d·tan θ<(25.4/R)×1000 is satisfied.in-line-formulae description="In-line Formulae" end="tail"?
