    Abstract: An image reading device includes reading devices arranged in a main scanning direction perpendicular to a sub-scanning direction, position reference members each including a reference pattern for correcting relative positions of pixels in each of the reading devices or relative positions of the reading devices, and circuitry. The reference members move in the sub-scanning direction relative to the reading devices, and include first reference members for correcting the relative positions of the reading devices and second reference members for correcting the relative positions of the pixels in each of the reading devices. While switching between the first reference members and the second reference members, the circuitry calculates a correction value for a deviation of the pixels in each of the reading devices and a correction value for a deviation of the reading devices based on a result of reading of the reference members.

  • Publication number: 20200006398
    Abstract: To make the dimension of an electrostatic protection circuit small with the same maintained high in sensitivity. The electrostatic protection circuit is of the configuration that a first diode and a second diode are connected in series, wherein a semiconductor layer owned by each diode is configured to be sandwiched between a gate electrode and a conductive light shielding film. The light shielding film is formed to overlap with the semiconductor layer and has a wider area than the semiconductor layer. This results in having a gate covering the semiconductor layer from an upper side and a back gate covering the semiconductor layer from a lower side, so that the sensitivity can be maintained high irrespective of decreasing the electrostatic protection circuit in dimension.
