An optical scanning device includes a light source, a deflector, a random number generator, a selection part, a random number assignment part and an exposure control part. The light source includes a plurality of light emitting parts arranged in a predetermined direction at fixed intervals in a sub-scanning direction. The random number assignment part is configured to assign a random number sequence to each light emitting part constituting a set of target light emitting parts as an index for specifying a timing at which a light emitting time of the set of target light emitting parts is set to a correction value different from a reference value and to update the assignment of the random number sequence at a random number update period. The random number update period coincides with a scanning period of each light emitting part constituting the set of target light emitting parts.

One motor is shared for carriage movement and document sheet conveyance. An abutting member stops the carriage, that has moved from a second position located below a first end portion of a platen glass, at a first position located below a contact glass. The carriage supports the motor and first and second main body gears. The main body gears interlock with the motor. A cover input gear meshes with the first main body gear when the carriage is located between the first position and a relay region. A main rack gear meshes with the second main body gear when the carriage is located in a region extending from the relay region to a third position located below a second end portion of the platen glass. A load torque applied to the motor is larger when the carriage is fixed than when the cover input gear is fixed.

An image reading apparatus includes an original illuminator; a reflector for reflecting light reflected by the original; a reading portion for reading the light reflected by the reflector; a holding member holding the reflection member; a first bonding portion connecting the holding member and one end portion of the reflector in a direction along a reflecting surface of the reflection member; and a second bonding portion connecting the holding member and the other end portion of the reflector in the direction along the reflecting surface of the reflection member. The second bonding portion has a hardness less than that of the first bonding portion.

An illumination device and an image reading device are characterized by including: a rod-shaped light guide extending in a longitudinal direction and configured to guide light entering from an exterior and emit the light as linear light from a lateral surface; a light guide holding portion having a hole into which an end surface of the light guide is inserted; a supporter supporting the light guide holding portion slidably along the longitudinal direction; and a housing supporting or housing the light guide, the light guide holding portion and the supporter, at least the supporter being fixed to the housing, a direction of sliding of the light guide holding portion being restricted to the longitudinal direction by a supporter-side concave-convex portion that is a supporter-side groove portion or a supporter-side protruding portion at least one of which is formed on the supporter along the longitudinal direction.

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.

An image reading apparatus includes: a conveyance portion configured to convey a first medium; a first imaging portion; a first reading processing portion configured to cause the first imaging portion to read a first image of a first reading surface of the first medium conveyed by the conveyance portion; a second imaging portion; a second reading processing portion configured to cause the second imaging portion to read a second image of the second reading surface of the second medium by scanning while the second imaging portion is being moved along a second reading surface of a second medium placed on a medium placement surface; a reading control portion configured to control the first reading processing portion and the second reading processing portion to operate in parallel with each other; and a synthesis processing portion configured to generate a synthesized image by synthesizing the first image and the second image.

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.

A system and method provides automated prediction of filenames and storage locations for scan files generated from a user's scan of their financial documents. A prediction model is generated for the user based on weighted values derived from preexisting filenames and preexisting storage locations for their stored electronic files. Text or images from each scan document is analyzed and weighted and compared to the user's prediction model and a suggested name and storage location is automatically generated. The suggestions are confirmed or corrected by the user prior to storage, and any corrections are used to update the user's prediction model.
