A foreign matter detection device which detects a foreign matter in an inside of a card reader. The foreign matter detection device includes a control part which performs control for causing an imaging device provided in the inside of the card reader to image a space in the inside of the card reader, and a detection part which detects the foreign matter in the space by image analysis based on a captured image obtained by the imaging device.

Foreign matter detection device, card reader, foreign matter detection method and recording medium preliminary

An information media processing device may include a transport passage in which an information medium having MICR characters printed in a predetermined print position is transported, a magnetic head arranged in the transport passage, an image reading means arranged in the transport passage, a transporting means arranged in the transport passage, which has a shifting mechanism for shifting the information medium into an area in which the magnetic head can make magnetic detection, and a controller which detects the reference edge of the information medium based on the image read by the image reading means to judge if the print position is distanced by a predetermined amount or more from the magnetically-detectable area of the magnetic head based on the reference edge; when the print position is distanced by a predetermined amount or more, the transporting means shifts the information medium into the magnetically-detectable area while transporting the information medium.

Information media processing device

A duplicate feeding detection device for use with sheet-like members may include a control part for controlling an ultrasonic transmission part, a duplicate feeding judging part for judging duplicate feeding of the sheet-like members on a basis of an output from an ultrasonic receiving part, a temperature measuring part for measuring temperature of a vicinity of the ultrasonic transmission part, and a memory part in which a relationship between an oscillation frequency of the ultrasonic transmission part and a temperature is stored. The control part sets an oscillation frequency corresponding to a temperature which is measured by the temperature measuring part on a basis of the relationship between the oscillation frequency and the temperature stored in the memory part.
