摘要： An apparatus for scanning a document, including scanning a photograph, the apparatus including a contact image sensor (CIS), the apparatus designed to reduce the friction between the contact image sensor and the document being scanned. The reduction is achieved by reducing the friction by use of a non-stick material or by reducing the static electricity forces or both. The preferred embodiment is a CIS whose housing is made of a non-stick material which also is static electricity dissipative.

摘要： 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.
