An imaging device provides a mobile device multi-feed scanner, which may utilize remote data capture for multi-sheet feed scanning by using mirrors to form a reflective path allowing the viewing of the reverse side of the check on a platform to capture the check image on a mobile device. A camera on the mobile device may either sequentially or simultaneously capture a picture of both the front and back sides of the check. The platform may include a transparent portion, which may be adjacent to a stage portion. The first and second mirrors may be positioned such as to allow imaging of a reverse side of an object through the transparent portion of the platform while the object rests on the stage portion.

Generally, a scanner of the present embodiment, which reads a first surface with a first reading section configured to read the first surface of a sheet and a second surface with a second reading section configured to read the second surface opposite to the first surface of the sheet, executes individual processing on a first reading image of the first surface and a second reading image of the second surface.

A read sensor generates front side image information indicating an image on a front side of an object to be read, and front side measurement information indicating a line of an image in a main scanning direction on the front side of a correction chart. A read sensor generates back side image information indicating an image on a back side of the object to be read, and back side measurement information indicating a line of an image in the main scanning direction on the back side of the correction chart. The image correction device calculates an amount of misalignment of read positions based on the front side measurement information and the back side measurement information, and corrects misalignment of images on the front side and the back side of the object to be read, indicated by the front side image information and the back side image information.

An image reading device includes a reading section having a plurality of optoelectronic transducers aligned in a main scanning direction, a sub-scanner causing the reading section to scan a first sheet and a second sheet in a sub-scanning direction, and a controller determining an adjustment value defining a length in the sub-scanning direction of image data output by the reading section based on first image data and second image data. The first sheet and the second sheet have the same size. In the first image data, an angle at which the first edge intersects with the main scanning direction is smaller than an angle at which the second edge intersects with the main scanning direction. In the second image data, an angle at which the second edge intersects with the main scanning direction is smaller than an angle at which the first edge intersects with the main scanning direction.

It is determined based on processing to be performed on image data generated by reading by a first reading unit and a second reading unit, whether to separate, into image data of the first surface and image data of the second surface, image data that has been generated by reading by the first reading unit configured to read the first surface of a document, and the second reading unit configured to read the second surface of the document, and that includes the first surface and the second surface. When it is determined to separate the image data, the image data including the first surface and the second surface is separated into the image data of the first surface and the image data of the second surface.

A document reading device including an image reader. The image reader includes a first reader to read a first image from a first face of a document fed by a document feeder and a second reader to read a second face of the document. An operation mode is switchable between a normal operation mode in which the image reader is in an operation enabled state and an energy-saving mode in which the image reader is in an operation stop state. In a return from the energy saving mode to the normal operation mode, the image reader performs a start-up operation including a first initial operation for returning the first reader to the normal operation mode and then performs a second initial operation for returning the second reader to the normal operation mode.

An image reading device includes a first unit to read one surface of a document in a first area facing a document path, a second unit disposed in the first area to read the other surface of the document, a first reference member facing the first unit at a first distance therefrom at a second position in a second area not facing the path, a second reference member facing the first unit at a second distance therefrom at a first position in the first area, a third reference member facing the second unit at the second distance therefrom, and a correction unit to correct, based on a difference between first data generated through reading of the first member by the first unit and second data generated through reading of the second member by the first unit, third data generated through reading of the third member by the second unit.
