Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

A suction device includes a suction hole member including a plurality of suction holes, a suction pump connected to each of the plurality of suction holes, the suction pump configured to suction an air through the plurality of suction holes of the suction hole member to suction a suction target to the suction hole member, and a suction state detector configured to detect a suction state of at least one of the plurality of suction holes corresponding to an end of the suction target suctioned to the suction hole member.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A scanner unit includes a first reading section that reads a medium via a transparent member; and a bracing member that pushes the medium toward the transparent member by a coil spring. The bracing member includes a contact portion coming into contact with the transparent member in a downstream of a first reading region, and a gap forming surface that is positioned in a direction further away from the transparent member than the contact portion, which includes the first reading region, in an upstream of the contact portion, and is formed with a gap in which the medium is configured to be transported between the pushing member and the transparent member. A pressing position of the pushing member by the coil spring is shifted from a position of the contact portion in a medium transporting direction.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.
