IMAGE PICK-UP DEVICE AND POS SYSTEM INCLUDING THE SAME

摘要

An image pick-up device, which photographs an object to generate an image signal, including: an opening formed to pass light therethrough; a transparent plate which covers the opening; an image detector arranged to generate the image signal; an optical lens forming an image of the object on the image detector through the transparent plate when the object is positioned in an imaging area; a lighting device arranged to illuminate the object and is placed both in an inner area in which the imaging area outside the housing is folded into the housing with reference to the transparent plate, and in an outer area of the imaging area in the housing; and an optical-path modifying element which modifies an optical path of a potential stray light.

主权项

1. An image pick-up device, which photographs an object to generate an image signal representing the object, comprising:
a housing to which an opening is formed to pass light therethrough; a transparent plate which covers the opening and has a first surface facing the object and a second surface opposite to the first surface; an image detector arranged in the housing to generate the image signal; an optical lens forming an image of the object on the image detector through the transparent plate when the object is positioned in an imaging area from which light reaches the image detector through the optical lens; a lighting device for emitting light which is arranged in the housing to illuminate the object and is placed both in an inner area in which the imaging area outside the housing is folded into the housing with reference to the first surface, and in an outer area of the imaging area in the housing; and an optical-path modifying element which modifies an optical path of a potential stray light resulting from the light which is emitted by the lighting device and is reflected by at least one of the first and second surfaces.
