Abstract: An image scanner is provided to obtain a high quality image by removing an optical interference pattern from a forgery/alteration preventing element recorded on a medium, and keep high preciseness and reliability while obtaining the high quality image by scanning both sides of the medium at the same time. A loading track guides loading of the medium(2) having the forgery/alteration preventing element generating the optical interference pattern. A loader loads the medium by being mounted along the loading track. An image sensor is mounted to obtain image data from the medium loaded along the loading track. The image sensor includes a light source(132), a light receiver(134), the first polarizer(136a) polarizing light output from the light source at a front side of the light source, the second polarizer(136b) polarizing the light reflected from the medium at the front side of the light receiver and having a phase difference of 90‹ to the first polarizer, and a lens(138) guiding the light passing the second polarizer to the light receiver.

Abstract: In an image sensor including a light emitting element for emitting a light beam to be incident on a document, a light receiving element for receiving the light beam reflected by the document, and a lens array for directing the reflected light beam from the document to the light receiving element, there is located a mirror between the lens array and the light receiving element for changing the direction of the light beam passing through the lens array. The light emitting element and the light receiving element are located on the same substrate. With this arrangement, a compact and inexpensive image sensor can be achieved. This compact image sensor causes an increased amount of light to be incident on the document.

Abstract: An illumination device includes a light guide made of plastic, and a light source including a light emitting element whose dominant wavelength is a light emission wavelength in an infrared region, and identifies a banknote. White reference plates are provided at positions that are at opposite ends of a rod lens array and cover respective areas external to an image region across the banknote. A correction coefficient is acquired by calculation. The calculation is made by correcting an illuminance such that IR correction data is substantially identical to IR reference data preliminarily stored in a memory circuit in a signal processor on the basis of IR white reference data representing a white reference illuminance generated from light reflected from the white reference plates. The correction coefficient is used for correcting IR image data when the banknote is read.
