IMAGE PICK-UP DEVICE AND POS SYSTEM INCLUDING THE SAME
First Claim
1. An image pick-up device which photographs an object to generate an image signal representing the object, comprising:
- a housing including an opening 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, configured to emit light, which is arranged in the housing to illuminate the object and 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 causes an optical path of the light emitted by the lighting device to be refracted such that the light is emitted from a virtual image of the lighting device, the virtual image being placed outside the inner area.

Abstract
An image pick-up device which photographs an object to generate an image signal representing the object, including: a housing including an opening; a transparent plate which covers the opening; an image detector arranged in the housing; an optical lens forming an image of the object on the image detector through the transparent plate; a lighting device arranged in the housing and placed both in an inner area in which an imaging area outside the housing is folded into the housing with reference to one surface of the transparent plate, and in an outer area of the imaging area; and an optical-path modifying element which causes an optical path of the light to be refracted such that the light is emitted from a virtual image of the lighting device, the virtual image being placed outside the inner area.

6. A POS system having an image pick-up device which photographs an object to generate an image signal representing the object, and a POS terminal which executes a sales registration processing in accordance with the image signal, the image pick-up device comprising:
-
a housing including an opening 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, configured to emit 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 causes an optical path of the light emitted by the lighting device to be refracted such that the light is emitted from a virtual image of the lighting device, the virtual image being located outside the inner area. - View Dependent Claims (7, 8, 9, 10)
