    摘要: An image forming apparatus includes a carriage carrying a recording head configured to discharge a droplet. A landing position error detecting pattern is formed on a pattern forming member. Based on a result of reading the landing position error detecting pattern, a landing position error of the droplet discharged by the recording head is corrected. Either a first pattern or a second pattern is selected as the landing position error detecting pattern, depending on a surface condition of the pattern forming member. The first pattern produces a relatively small amount of specular reflection compared with diffused reflection, while the second pattern produces a relatively large amount of specular reflection compared with diffused reflection, upon irradiation with light.

    摘要: A side wall surface of a carriage is disclosed with two first projection parts and a second projection part that define the inclination of a reflective optical sensor in its vertical direction. The two first projection parts are arranged at the same height position with a detection surface as a reference, and the second projection part is arranged at a position higher than the first projection parts with the detection surface as the reference. The second projection part has a first part higher in position from the side wall surface of the carriage than the first projection parts and has a second part lower in position than the first part. The second part has a screw hole into which a clamping member for fixing the reflective optical sensor to the second part is tightened.

    摘要: An apparatus includes: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the source to the subject. When a specular position of the source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the source toward the first specular position and an incident angle from the source toward the second specular position is a reference value or more.
