Read data of a plurality of optical information reading devices can be compared on a spatial axis. A setting device includes: a communication part for communicating with each of the optical information reading devices; a display part that displays a list of pieces of read data, conveyor, of any one of a plurality of optical information reading devices; an input part that receives an input for selection of any one piece of read data from the list of pieces of read data displayed on the display part; and a control part that acquires a code image having the read data selected by the input part from another optical information reading device connected to the network, and performs comparison display, on the display part, of a plurality of the code images respectively acquired by different ones of the plurality of optical information reading devices.

Setting device for optical information reading device, optical information reading system, and optical information reading method

An optical information reading deviceincludes an aiming moduleconfigured to irradiate aiming light for instructing an imaging area of image data generated by an imaging module, a trigger switchfor starting imaging processing by the imaging module, an aiming switchB for causing the aiming moduleto irradiate the aiming light, and a reading unitconfigured to read information of the symbol. The reading unitis configured to, in an aiming state in which irradiation processing for the aiming light by the aiming moduleis executed by operation of the aiming switchB, detect that the trigger switchis operated and read, based on the image data generated by the imaging processing of the imaging module, information of the symbol included in a predetermined partial area PA corresponding to an irradiation position of the aiming light.

Hand-held scanner

A portable optical reader is provided with: a reading partoptically reading a symbol as a reading object; a head partstoring the reading partand having a reading portfor the reading part; a holding partcontinuously connected to the head partand extending in a connecting direction; and a display partprovided in the head partand displaying at least a reading result. The head partis formed by side surfaces, and the display partis provided in at least two side surfaces which are a side surface facing to a surface providing the holding part, and a side surface in which a reading direction by the reading partand an extending direction of the holding partare substantially orthogonal to each other.

Portable optical reader

A portable optical reader is provided with LED light sourcesto; a diffusion platediffusing the light emitted from the LED light sourcesto; an openingformed on the diffusion platetransmitting diffusion reflecting light; an imaging partreceiving the diffusion reflecting light through the opening; a LED light sourceemitting the light to the symbol; a light projection polarizing elementpolarizing the light emitted from the LED light source; an openingformed in the diffusion platetransmitting the polarized light emitted from the LED light source; and a light reception polarizing elementpolarizing the diffusion reflecting light which is the polarized light emitted from the LED light sourceand reflected on the symbol and transmitted through the opening

There is provided an external illumination apparatus capable of increasing flexibility of illumination, the external illumination apparatus including a CPU and a memory so as to control lighting of a plurality of illumination LEDs with reference to a lighting pattern stored in the memory, wherein this lighting control is executed by a lighting command from an optical information reading apparatus.

External illumination apparatus for optical information reading apparatus

An ionizer of a corona discharge type is configured to increase the yield of ions while minimizing contamination of a discharge electrode by foreign matters. In the ionizer, a gas path unit () supplied with clean gas has internal clean gas paths () in an electrode assembly (), and clean gas is released through each internal clean gas path () to make a clean gas flow enclosing a front end portion of a discharge electrode (). The electrode assembly () has a guard ring () encircling the discharge electrode (), and the guard ring () has external air inlet openings () permitting free passage of atmospheric air. The clean gas flow enclosing the tip of the discharge electrode () inhales atmospheric air through external air inlet openings () of the guard ring () and changes to ionized air.
