Baseline values for metal detection readings associated with an item inserted into an infeed mouth of a depository are obtained before the item is pinched on a pathway of the depository. The baseline values are adjusted by additional readings obtained when the item is pinched on the pathway for transport. The adjusted baseline values are processed with calculated values from ongoing and fluctuating current readings to determine at least one final value. A determination is made as to whether the item includes at least some metal based on comparison of the at least one final value and a predefined value.

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.

In a bank-note processing machine, bank notes are guided through between two components of a checking device by means of a transport band. The transport band is led away at least partly from the checking device by means of deflection rollers to enable a better check of the bank notes and a trouble-free transport of the bank notes.

A device for detecting a foreign object attached on a surface of a sheet-like medium, comprising a static electricity providing part (A) for providing static electrical charges, a medium transporting part (B) for transporting a medium under detection, and a static electricity sensor and identifier part (C). The medium transporting part comprises a static electricity receiving unit and a static electricity absorbing unit sequentially connected. The static electricity receiving unit is connected to the static electricity providing part (A), and the static electricity absorbing unit is connected to the static electricity sensor and identifier part (C). The static electricity receiving unit is configured to transfer the static electrical charges obtained from the static electricity providing part (A) to the medium under detection. The static electricity absorbing unit is configured to absorb the static electrical charges of the medium under detection.

An apparatus and method for checking value documents, in particular bank notes, and a value document processing system having at least one sensor for capturing an electromagnetic radiation transmitted by a value document and generating corresponding transmission signals, and an evaluation device for checking whether the value document has a foreign object taking into account the transmission signals. From the transmission signals an edge course of the value document is derived and a rectangle is approximated to the edge course. By comparing the edge course of the transmission image with the rectangle, the presence of a foreign object such as an adhesive tape, can be ascertained.

An image sensor and a banknote processing apparatus are provided. The image sensor includes a first photosensitive assembly and a first light source assembly which is configured to irradiate light to an original, and further includes a first lens array configured to aggregate light reflected by the original to the first photosensitive assembly, and a light-entering surface of the first lens array is located in a transmission path of reflected light generated due to specular reflection occurred when light emitted from the first light source assembly irradiates on the original. According to different image grayscale values generated by the image sensor, the banknote processing apparatus judges whether a banknote surface is stuck to an adhesive tape.

A paper-sheet-thickness detecting sensor of the present invention includes: an oscillator that outputs high-frequency signals with frequencies corresponding to positions in a horizontal direction that is orthogonal to a direction in which a paper sheet is transported; a signal electrode to which the high-frequency signals output by the oscillator are applied; a plurality of detection electrodes that face the signal electrode across a transportation path for the paper sheet and that individually detect detection signals that correspond to the positions; a plurality of resonance circuits that each have one end connected to one end of each of the plurality of detection electrodes and that have resonance frequencies equal to the frequencies allocated to the positions; and a broadband amplifier to which another end of each of the plurality of resonance circuits is connected and that outputs outputs of the plurality of resonance circuits as one piece of sensor output information.
