Embodiment Construction

[0022] Next, embodiments of an imaging device and an object recognition scanner including the imaging device will be described with reference to the drawings. This embodiment is applied to a vertical product recognition device installed at a checkout counter installed in a store such as a supermarket.

[0023] figure 1 It is an external view of a store system including the product recognition device according to the present embodiment. This store system includes a product recognition device 100 and a POS (Point Of Sales: point of sale) terminal 200 . The commodity identification device 100 is installed on the checkout stand 300 . The POS terminal 200 is installed on the drawer 500 placed on the cash register 400 . Commodity recognition device 100 and POS terminal 200 are electrically connected by a communication cable not shown. There is also a case where an automatic change machine is installed instead of the puller 500 .

[0024] The product recognition device 100 inclu...

Abstract

The invention discloses an imaging device and an object recognition scanner, which can suppress excess light incident and take high-quality images of commodities. The imaging device includes: a chassis, a substrate, a light emitting device, an imaging device and a light-shielding component. A case with a camera window formed on one side of the case. The substrate is disposed inside the housing, and at least a part of a surface facing the imaging window is treated to prevent light reflection. A light emitting device is mounted on the substrate and emits illumination light to the outside of the housing through the imaging window. An imaging device for imaging an object illuminated by the illumination light through the imaging window. A light-shielding component is arranged inside the casing, and blocks at least a part of reflected light from various places inside the casing from entering the imaging device in a manner that does not hinder the imaging.

Description

[0001] This application claims the priority of the Japanese application with the filing date of October 25, 2013 and the application number JP2013-222731, and cites the content of the above application. technical field [0002] The invention relates to an imaging device and an object recognition scanner. Background technique [0003] There is a product recognition device that extracts and analyzes the product by barcode extraction and analysis from an image of the product captured by an imaging device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor: Complementary Metal Oxide Semiconductor). The target object is identified to identify the product. [0004] In this kind of commodity recognition device, a light source is often provided inside a housing housing the imaging device, and the commodity is illuminated by the light emitted by the light source. [0005] In the product recognition device configured in this way, the light emitted...
