摘要： A non-scanning type optical reading apparatus for reading patterns such as a bar code. The optical reading apparatus comprises an imaging lens for imaging a bar code as a pattern to be read, a CCD line sensor for reading the information of the image of the pattern, and a light damping mirror and/or filter that is provided between the pattern and the CCD line sensor. The central part of the light damping mirror filter is denser than the periphery to achieve a uniform distribution of light on the sensor. According to one embodiment, the filter is a bandpass filter.

摘要： A surveying instrument comprising optical system means having an optical axis to be coincided with an object to be observed, positional deviation detecting means for detecting the deviation of said optical axis with respect to the object and either means for displaying the detection result of said positional deviation detecting means or means for driving said optical system according to the detection results of said positional deviation detecting means so as to bring said axis in coincidence with the object. According to the present invention, an observer can achieve surveying operation over watching the display, and thus easy and accurate operation is possible.
