摘要： A bar code label comprises a recording medium and a bar code recorded on a recording medium. The bar code includes a plurality of bar elements lined up parallel. Each width of bar elements is different in accordance with the kind of bar elements. The width of the bar elements is made wider than it would normally be based on its distance from the center of the bar code toward the end of the bar code.

摘要： Apparatus for optically reading printed information by radiating light onto printed information to be reflected thereby, receiving the reflected light through an optical system and converting the image of the reflected light into a corresponding electric signal. The light source employs red light emitting diodes which radiate highly bright red light having a wavelength peak at about 660 nm so that the image sensor can receive a highly contrasting reflected light from the information printed in black on a white base. The light source further or alternatively employs infrared light emitting diodes for radiating the light having a peak wavelength at about 925 nm so that the image sensor can also received a highly contrasting reflected light from information printed in black on a blue or green base.

摘要： Apparatus and method for recognizing optical information such as bar code has a light source and an image sensor which converts intensity of light reflected by the optical information into an electric image signal. The electric image signal is sample-and-held to detect the average intensity of light from the light source. The time interval for activating the light source is pulse width modulated in accordance with the detected average intensity in a previous operational cycle.

摘要： In an optical reading apparatus having a reading sensor for converting optically readable information into an electrical signal by electronically scanning an image of optical information, such as a bar code, a detector is provided to detect the intensity of light incident on an information label on which the information is provided. Data indicative of the light intensity is used to determine a subsequent scanning period in such a manner that the scanning period of the reading sensor is shortened when the light intensity increases or vice versa. Since the decrease in the scanning period results in lower output voltage from the reading sensor, undesirable saturation in circuitry following the reading sensor is effectively prevented, providing stable operation of the reading sensor, such as a bar code reader.
摘要翻译：在具有用于通过电子扫描光学信息的图像（例如条形码）将光学可读信息转换为电信号的读取传感器的光学读取装置中，提供检测器，以检测入射在信息标签上的光的强度，提供信息。使用指示光强度的数据来确定随后的扫描周期，使得当光强度增加时读取传感器的扫描周期缩短，反之亦然。由于扫描周期的减少导致来自读取传感器的较低的输出电压，因此有效地防止了读取传感器之后的电路中的不期望的饱和，从而提供诸如条形码阅读器的读取传感器的稳定操作。
