IMAGE DATA TRANSFER CONTROL DEVICE AND IMAGE DATA TRANSFER CONTROL METHOD
An image data transfer control device includes a first interface, a first and a second memory, a processor, and a second interface. The first interface acquires image data transferred in predetermined units. The first memory stores inclination correction data corresponding to the inclination of a print head, and correction position data indicating a correction position included in at least one divided image line among the predetermined number of divided image lines including each divided image line group. The second memory stores correction target image data at the correction position. The processor selects each divided image line group based on the inclination correction data, and specifies first and second correction target image data. The second interface outputs the second divided image line group including the first correction target image data instead of the second correction target image data.
Scanner module and image scanning apparatus employing the same
A scanner module and an image scanning apparatus employing the same. The scanner module comprises an illuminator for illuminating light on an object to be scanned. The illuminator includes a light emitting diode, a light guide extending in a main scanning direction to change a direction of the light received from the light emitting diode, and at least one elastic member to elastically support at least one longitudinal end of the light guide. As the light guide is elastically supported by the elastic member, convex deformation or bowing of an emission face of the light guide due to thermal expansion can be reduced.

LENS ARRAY UNIT, IMAGE SENSOR UNIT, IMAGE READING APPARATUS, IMAGE FORMING APPARATUS, AND METHOD OF MANUFACTURING LENS ARRAY UNIT
A lens array unit includes a lens array including a plurality of lenses, a first side plate, and a second side plate, the first side plate and the second side plate being configured to hold the plurality of lenses therebetween, and a frame made of resin and including a first supporting portion and a second supporting portion, the first supporting portion being in contact with an outside surface of the first side plate, the second supporting portion being in contact with an outside surface of the second side plate, the first supporting portion and the second supporting portion being configured to hold the lens array therebetween and support the lens array. The outside surface of the first side plate includes a plurality of first concave portions spaced from each other in an array direction of the lenses and configured to fit with the first supporting portion.
Thermal management of an optical scanning device
Thermal variations on an optical scanning device can affect measurements made by that device. Various ways are presented here to control the temperature of a device and compensate for temperature variations of the device.
IMAGE READING APPARATUS AND IMAGE FORMING APPARATUS
An image reading apparatus for reading an image of an original includes an illumination portion for illuminating the original with light, a reflection member including a reflecting surface for reflecting the light from the original; a converting portion for photoelectrically converting the light reflected by the reflection member, and a casing for accommodating the reflection member. The casing is provided with an opening which is open to an outside of the casing. A surface of the reflecting member opposite from the reflecting surface and a portion defining the opening are bonded to each other with an adhesive.
Image reading apparatus provided with guide rail to guide image reading unit to read document and fix the guide rail with an adhesive
An image reading apparatus, including: a guide rail configured to guide an image reading unit; and a fixing portion having configured to fix the guide rail with an adhesive.
Print media scanning system
A print media scanning system enables the rapid acquisition of books, magazines, papers and so on into a digital library. The media is placed on an inclined surface where is held in place and the pages to be scanned are secured by braces. A scanning head is suspended above the media and is adjustable with respect to the media. The data from the scanning head is transferred to a digital library.
Scanning device light guide assembly having compliant member
A light pipe is mounted to a support structure along a length of the light pipe. The light pipe has an end at which light enters the light pipe. Light exits the light pipe at an emissive surface of the light pipe. A reflective backing is positioned at a surface of the light pipe opposite the emissive surface. A compliant member between the reflective backing and the support structure maintains the reflective backing flush against the surface of the light pipe.
Laser control in scanners
An example device including a laser source for generating a laser pulse, a scanner for mounting the laser source, and a motion detector for detecting a motion of the scanner when the laser pulse scans an object. The motion detector includes an optical sensor for generating an optical signal based on the motion of the scanner, and a controller. The controller determines a movement of the scanner and disables the laser source when the scanner ceases to move.
