A second conveyance roller group includes at least one of the plurality of conveyance rollers downstream from the leading end of the sheet stopped by the stop control in the conveyance direction, to which the driving force is transmitted without the clutch.

Print data generator, printer, method, and computer-readable medium for generating print data in the HSV color space reducing colorants used

A print data generator includes a storage storing processor-executable instructions causing a processor to perform a process to generate print data from original full-color data. The process includes when a hue value of a pixel is within a specific hue range for an emphasis color, setting a density value of a reference color of the pixel based on a value value of the pixel, and setting a density of the emphasis color of the pixel based on a saturation value of the pixel and a difference value between the hue value of the pixel and a hue value of the emphasis color, and when the hue value of the pixel is out of the specific hue range, setting the density value of the reference color based on a luminance value of the pixel derived from RGB data, and setting the density value of the emphasis color to zero.

GUIDING STRUCTURE ADAPTED FOR A SCANNER AND CAPABLE OF PREVENTING IMAGE DISTORTION AND SCANNER THEREWITH
20190007577 · 2019-01-03 ·

A scanner includes an image capturing module, a drive roller assembly, an idle roller assembly, and a guiding structure. The image capturing module is for capturing an image of an object. The drive roller assembly is for driving the object to move along a feeding direction. The idle roller assembly is for preventing a moving direction of the object away from the feeding direction by resiliently pressing the object. A feeding passage is formed between the drive roller assembly and the idle roller assembly. The guiding structure is disposed in front of the feeding passage and for guiding a normal direction of a leading edge of the object to be oblique relative to the feeding direction at an oblique angle. Therefore, the present invention can effectively reduce variation of a resistance force acting on the object as the object moves in the feeding path, which prevents image distortion.

Image reading apparatus and image forming system

An image reading apparatus includes an image reading sensor, a transparent plate, a guiding member, a first roller pair, and a second roller pair provided upstream of the first roller pair with respect to a sheet feeding direction. The first roller pair and the second roller pair are disposed so as to nip a sheet in each of nips of the first roller pair and the second roller pair when a leading end of the sheet enters between the guiding member and the transparent plate.

An image reading apparatus includes a conveyance member, a transparent member, a background member, and a reading unit. The reading unit arranged on an opposite side to the background member with respect to the transparent member. The reading unit includes a light source and a reading sensor. The light source emits light toward a sheet. The reading sensor reads a shadow of a sheet and an image of the sheet through the transparent member. The shadow of the sheet is projected onto the background member. As viewed in a width direction perpendicular to a conveyance direction, an irradiating direction of the light inclines downstream in the conveyance direction toward a downstream side in the irradiating direction. The background member has a planar shape that is inclined to approach the transparent member from an upstream side toward a downstream side in the conveyance direction.
