Abstract:
First and second signal wiring patterns are formed in a first conductor layer. A first electrode pad electrically connected to the first signal wiring pattern through a first via and a second electrode pad electrically connected to the second signal wiring pattern through a second via are formed in a second conductor layer as a surface layer. A third conductor layer is disposed between the first conductor layer and the second conductor layer with an insulator interposed between those conductor layers. A first pad electrically connected to the first via is formed in the third conductor layer. The first pad includes an opposed portion which overlaps the second electrode pad as viewed in a direction perpendicular to the surface of a printed board and which is opposed to the second electrode pad through intermediation of the insulator. This enables reduction of crosstalk noise caused between the signal wirings.

A printed circuit board (PCB), which can be implemented on a battery set, having a plurality of soldering holes thereon. A soldering portion and a non-soldering portion are separately arranged around each of the soldering holes on both surfaces of the PCB. Each corresponding conductive stick can respectively pierce each soldering hole and be fixed to each soldering portion of the PCB with the fused solder or move from the soldering portion to the non-soldering portion in the soldering hole. Thus, this invention provides a convenient and efficient way for assembling the PCB on the battery set or disassembling the PCB apart from the battery set.

Abstract:
The invention is an optical reader having a plurality of imaging modules. In one method for operating a multiple imaging module reader of the invention, a second frame of image data captured via actuation of a second imaging module is automatically captured and subjected to decoding in the case an attempt to decode using a frame of image data captured via actuation of a first imaging module fails. In another embodiment, a frame of image data captured via actuation of an image sensor of a first module and actuation of illumination of a second imaging module is subjected to decoding. In another embodiment, frames of image data captured via actuation of image sensors of spaced apart modules are combined. The various modules of a multiple imaging module reader can be adapted to have different best focus positions so that a field depth of the reader is improved.
