摘要： An inkjet printer is configured to acquire gap variation information related to a variation of a gap between a specific portion of an ink discharging surface and a recording sheet as a function of an inkjet head position, the specific portion located within a usage nozzle disposed area where usage nozzle rows to be actually used are disposed, determine representative gap variation information related to a variation, as a function of the inkjet head position, of a representative gap representing actual gaps between the usage nozzle rows and the recording sheet, by multiplying the gap variation information by a correction coefficient dependent on a width of the usage nozzle disposed area in a head moving direction and a wavelength of a wave shape of the recording sheet, and determine ink discharging timing based on the representative gap variation information, assuming that the actual gaps are equal to the representative gap.

摘要： A conveyance device includes a linear encoder that outputs an encoder signal corresponding to displacement of a conveyed object. The encoder includes an encoder fence provided on an intersecting plane that intersects a reference plane orthogonal to a direction in which a guide element supports the conveyed object. The encoder fence is configured such that a plurality of light-transmitting portions and light-shielding portions are arranged alternately on a side of the encoder fence. The light-transmitting portions and the light-shielding portions are formed so that a first point on each boundary between each of the light-transmitting portions and each of the light-shielding portions adjacent to each other and a second point on the each boundary, which is positioned separately from the first point with respect to a direction along the side of the encoder fence and perpendicular to the conveying direction, are separately positioned with respect to the conveying direction.

摘要： A sheet-conveying device conveys a recording medium to a sheet support surface positioned downstream of the sheet-conveying device in a sheet-conveying direction when recording an image with an image-recording unit. A drive roller and a follower roller define a nip line therebetween. The nip line is positioned above the sheet support surface. A first support member rotatably supports the follower roller. A moving unit moves the first support member from a first position to a second position upstream of the first position in the paper-conveying direction immediately after a trailing edge of the recording medium leaves the sheet-conveying unit.

摘要： A drive roller and the follower roller defines a nip line therebetween. A recording medium has a leading edge provided with a first corner contactable with the drive roller and a second corner contactable with the follower roller at a contact line when the drive roller and the follower roller provide the nip line. A supporting unit supports the follower roller and is capable of retracting the follower roller away from the nip line in a retracting plane. The retracting plane contains the axis of the follower roller. An angle α1 and α2 greater than the angle α1 is defined between the retracting plane and an imaginary plane that contains the axes of the drive roller and follower roller. The supporting unit allows the follower roller to be retracted in a downstream side of the paper conveying direction with respect to the imaginary plane. The angle α1 is greater than an angle β defined between the imaginary plane and a radial plane passing through the second axis and the contact line.
