Abstract: An image reading portion includes a light emitting portion and a plurality of photoelectric conversion elements. The light emitting portion emits detection light to a target area extending over a surface of a conveying belt and a pair of off-belt areas outside the conveying belt in a width direction. The image reading portion outputs a plurality of pixel data items. A reference member forms a pair of boundary lines by the difference in reflectance of the detection light at a pair of reference positions in the pair of off-belt areas. A calibration portion identifies data items corresponding to the pair of boundary lines in the plurality of pixel data items obtained by the image reading portion so as to correct reference position data representing a correspondence relationship between the plurality of pixel data items and positions in the width direction.

Abstract: An inkjet recording apparatus includes a recording head, a waste ink tray, an ink inflow section, an ink detecting section, and a controller. The recording head ejects ink. The waste ink tray recovers the ink. The ink inflow section is located on the waste ink tray. The ink flows into the ink inflow section. The ink detecting section outputs a detection signal indicating whether there is the ink or not. The ink inflow section has a first inflow opening and a second inflow opening. The second inflow opening is located at a position higher than a position of the first inflow opening. The ink detecting section detects whether or not the ink has flown into the second inflow opening. The controller, upon receiving the detection signal, detects that the first inflow opening is clogged.

Abstract: A fixing device includes first and second rollers, a pressure adjustment mechanism, a drive input gear, a ratchet mechanism, and a transmission mechanism. The pressure adjustment mechanism changes a pressing posture of the first and second rollers. The drive input gear device receives a torque of a first rotational direction around an axis of the gear device and another toque of a second rotational direction. The ratchet mechanism, when the drive input gear device receives the torque of the first rotational direction, transmits the torque to the first roller, and in the case of the torque of the second rotational direction, suspends a torque transmission. When the drive input gear device receives the torque of the second rotational direction, the transmission mechanism exerts a driving force to the pressure adjustment mechanism. The drive input gear device includes a housing portion housing a part of the ratchet mechanism.

Abstract: A sheet feed cassette includes an end cursor, a pair of gears, and a pair of racks. The end cursor regulates a rear end position of stored paper sheets in the sheet feed direction. The end cursor is slidable in the conveyance direction. The pair of gears are rotatably provided on a lower surface of a base portion of the end cursor and have the same module and the same number of teeth. The pair of racks are provided on a bottom surface of a cassette main body in parallel with each other along a slide direction of the end cursor. The pair of racks respectively mesh with the pair of gears. This makes it possible to prevent a defect such as skewing, a folded edge, or a wrinkle from occurring, allowing the end cursor to slide smoothly with excellent operability.
