Optical code reader having plural spot beams which intersect one another a preset distance away from a reading window of the optical code reader
摘要：
An optical code reader includes a reading window, a reading control circuit for sensing an image of a 2-dimensional code via the reading window in a state where the reading window is set within a preset distance from the 2-dimensional code and converting the sensed image into image data, a guide light source for applying a guide light beam to permit the 2-dimensional code to be guided within the reading range of the reading control circuit, and a portable frame having an opening used as the reading window, for accommodating the reading control circuit and guide light source. In the optical code reader, the guide light beam indicates the center of the reading range and is applied from the guide light source except for a period during which the image of the 2-dimensional code is sensed by the reading control circuit.
摘要（中）：

光学代码阅读器包括读取窗口，读取控制电路，用于在将读取窗口设置在与二维代码预设的距离内的状态下经由读取窗口感测二维代码的图像，并且将感测到的 图像转换成图像数据，用于施加引导光束以允许在读取控制电路的读取范围内引导2维代码的引导光源，以及具有用作读取窗口的开口的便携式框架，用于容纳 读取控制电路和引导光源。 在光学代码读取器中，引导光束指示读取范围的中心，并且除了由读取控制电路感测到二维码的图像的时间段之外，还从引导光源施加。
