リーダ。[Claims for Utility Model Registration] (1) A plurality of photo sensors are arranged corresponding to a plurality of code elements that are binarized due to different reflective surfaces, and the reflection of each of the above code elements when a light source is turned on is provided. In a device that detects light with each of the photo sensors and reads the code represented by the plurality of code elements based on the output of each of the photo sensors, a detection element is provided in proximity to the plurality of code elements, and the detection element A detection photo sensor is installed at a position corresponding to
and a means for determining whether or not the output of the detection photo sensor turns ON/OFF in conjunction with the ON/OFF of the light source, and only when the above-mentioned interlock is confirmed, the plurality of photo sensors A code reader characterized in that the code reader is configured to enable reading of the above-mentioned code by the code reader. (2) The code reader according to claim 1, which is a utility model, and is configured to be able to notify the determination result based on the output of the detection photo sensor.
