READING DEVICE

摘要

A reader device includes a mounting surface on which a passport with a page to be read is placed, a light source for illuminating the page to be read, and a camera for picking up an image of the page to be read. The light source is arranged outside a front area of the page to be read. The page to be read contains a near-edge code positioned close to an edge of the page to be read. The light source includes an infrared LED array and a white LED array. An infrared LED and a white LED included in the infrared LED array and the white LED array, respectively, and located at a near-edge code position corresponding to the near-edge code are arranged closer to the page to be read than the other infrared LEDs and white LEDs in a direction perpendicular to the mounting surface.

主权项

1. A reader device unit for reading a surface of an object, said reader device comprising:
an object placing unit on which the surface is placed; a plurality of light emitting sources, which include a plurality of first light elements and a plurality of second light elements capable of emitting light in different frequency band from the first light elements, capable of illuminating the surface placed on the object placing unit; an imaging unit capable of picking up an image of the surface illuminated by the light emitting source, wherein the plurality of first light elements include at least a left side first light element, a middle first light element, and a right side first light element, the middle first light element is positioned in an area between the left and right side first light elements; the plurality of second light elements include at least a left side second light element, a middle second light element, and a right side second light element, the middle second light element is positioned in an area between the left and right side second light elements and wherein a first distance between the left side first light element and the middle first light element is different from a second distance between the right side first light element and the middle first light element, and a third distance between the left side second light element and the middle second light element is different from a fourth distance between the right side second light element and the middle second light element.
