An image forming system includes an image reading device which reads an image of a sheet conveyed along a conveyance path. The image reading device includes a reading sensor and a moving mechanism. The reading sensor optically reads the image. The moving mechanism moves the reading sensor to a reading position closer to the conveyance path and readable the image and a non-reading position separated from the conveyance path farther than the reading position.

An image scanning system of the present invention uses an image capturing unit moving unidirectionally along an optical axis direction, such that an object is positioned within a range of the depth of field of the image capturing unit. The optical axis direction is perpendicular to a plane, and a platform bearing the object and the plane form an included angle, such that multiple inclined surfaces of the object face the same end of a scanning direction, or such that one of the multiple inclined surfaces is parallel to the plane and other inclined surfaces face the same end of the scanning direction, wherein the scanning direction is parallel to the plane. Therefore, in the process of one-time scan, the scanning height of the image capturing unit only rises unidirectionally or descends unidirectionally and has no turning point, and thus, no backlash problem will happen.

There is provided an image scanner apparatus, including: a platen; a carriage including an image sensor that captures an image of a script on the platen; an antenna unit on the carriage; and a controller circuit that controls the carriage to move in a forward way and a backward way in a sub-scanning direction over the platen, detects a position of an NFC (Near Field Communication) tag on the script in the sub-scanning direction via the antenna unit, and then detects a position of the NFC tag in a main-scanning direction via the antenna unit.

An image reading apparatus includes a medium reading unit that extends in a main scanning direction and reads an image of a medium while moving in a sub-scanning direction which is a direction crossing the main scanning direction; a signal transmission cable that is a flexible cable having a curved section and connected to the medium reading unit and that deforms following a movement of the medium reading unit; a power supply that supplies power to the medium reading unit; and a housing that accommodates the medium reading unit and the power supply. At least a portion of an insertion/extraction space for inserting/extracting a plug of a power cable from outside the housing to the power supply and at least a portion of an area where the signal transmission cable deforms following the movement of the medium reading unit overlap in a height direction of the medium reading unit.

The disclosure provides a scanning device including a flatbed scanner and an ADF. The flatbed scanner includes a first body, a transparent substrate disposed on top surface of the first body, a first film disposed on top surface of the transparent substrate, and an image capturing module disposed under bottom surface of the transparent substrate. The ADF includes a second body, a backplane disposed at bottom of the second body for covering top surface of the flatbed scanner, a paper passage disposed inside the ADF, and a second film. An open portion is configured in the paper passage corresponding to top surface of the transparent substrate, and results communication between the paper passage and top surface of the transparent substrate. The second film is disposed at paper entrance of the open portion. Wherein, the first film and the second film are not overlap on top surface of the transparent substrate.

An image reading apparatus is provided. The image reading apparatus includes: a platen glass; a moving member; a reading section held by the moving member, the reading section having a reading surface, a light-receiving element, a substrate section, and a case section; a transmission member; and a first biasing section. The moving member includes a facing surface that faces the substrate section. The case section includes a first wall and a second wall. The transmission member includes a first contacting section, a second contacting section, and a connecting section. The first biasing section is disposed such that its one end makes a contact with the facing surface of the moving member and its other end makes a contact with the connecting section of the transmission member.

A scanning device includes a transparent platen which receives a sheet to be scanned. A backing assembly is spaced from the platen by the sheet during scanning. The backing assembly includes a backing plate of a fixed color and an electrochromic layer intermediate the backing plate and the platen. The electrochromic layer has a first state in which the electrochromic layer is opaque and has a different color from the fixed color, and a second state, in which the electrochromic layer is transparent to expose the backing plate through it. A sensor is positioned to acquire an image of the sheet based on light passing through the platen. A controller selectively applies a voltage across the electrochromic layer to change the electrochromic layer between the first and second states.

In order to mitigate image defects caused by unwanted disturbances as a carriage module travels from a continuous velocity transport module across a CVT ramp to a platen module, a bottom surface of the CVT ramp is recessed relative to bottom surfaces of the CVT glass and platen glass to facilitate a smooth transition as the CIS carriage passes the CVT ramp during scanning. An additional carriage button is also provided on the carriage surface to ensure that at least two carriage buttons are biased against the CVT-platen assembly at all times, thereby mitigating vibrational disturbance in the system during scanning motion. The carriage module may be a contact image sensor (CIS) carriage module, a Full Width Array (FWA) carriage module, or a folded Charged Coupled Device (CCD) carriage module.

An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.

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, arid setting the density value of the emphasis color to zero.
