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.

Abstract: A protruding locking pawl is provided at an end of a light guide which corresponds to a first light input surface. A recessed locking portion is formed in a frame so that the locking pawl can be locked in the locking portion. A light blocking member is slidably loosely inserted into a position where the light blocking member covers a longitudinal end of the light guide which corresponds to a second light input surface. Even if expansion and contraction occurs in the longitudinal direction of the light guide, the design dimensions of a first gap A and a second gap B can be maintained; the first gap A is formed between the first light input surface and a first light source, and the second gap B formed between the second light input surface and a second light source. Therefore, possible leakage current can be prevented.
