Abstract
본 발명은 기호를 견향하기위한 북수개의 장치를 제거하고, 어떤 기호에 대하여 레저다이오드로부터의 빔을 주사히기 진 혹은 주사중에 용이하게 견향할수 있도록 하여, 주사전에 레저주사기에 대하여 기호를 정확하게 위치시키고, 주사중에 레저빔기로 상기 기호를 정확하게 추적할 수 있도록 하기 위한 광학척 주사장치에 관한 것으로서, 다음과 같이 구성한다. 휴대용 주사헤드로 기로를 견향하기 위해서, 임사광빔을 발생하는 레저를 헤드내에 형성하고, 헤드밖에 위치하며 또 입사레저빔의 전파방향과 직각인 평면에 있는 기준평면측으로 입사레지빔을 제1의 광학로를 따라서 지향시키는 정렌즈등의 광학적요소도 헤드내에 형성한다. 기호에서 발사된 레저관의 반환부분은 기호로부터 헤드의 방향으로 밀어져나가는 제2의 광학로를 따라서 진행한다. 주사밀러등의 반사면이 취부되고 왕복진동하여 기호를 주사한다. 또한 헤드는 반사된 레저광의 광강도를 나타내는 전기적 아날로그신호를 발생하기 위한 센서수단을 구비하며, 전기신호를 처리하여 주사되고 있는 기로를 나타내는 데이터를 디지탈전기신호로 처리하는 신호처리수단도 헤드에 취부된다.The present invention eliminates the number of devices for biasing a symbol and makes it easy to bias the beam from the leisure diode against any symbol during the scan or during the scan, thereby accurately positioning the symbol relative to the leisure syringe prior to the injection. The present invention relates to an optical chuck scanning apparatus for accurately tracking a symbol with a leisure beam during scanning, and is configured as follows. In order to face the crossroads with a portable scanning head, a leisure is generated in the head, and the incident light beam is directed to the reference plane side located outside the head and in a plane perpendicular to the propagation direction of the incident laser beam. Optical elements such as positive lenses orientated along the furnace are also formed in the head. The return portion of the leisure tube launched from the sign proceeds along a second optical path that is pushed out of the sign in the direction of the head. Reflecting surfaces such as scanning mirrors are mounted and reciprocated to scan symbols. The head also has sensor means for generating an electrical analog signal indicative of the light intensity of the reflected leisure light, and also has signal processing means for processing the electrical signal into a digital electrical signal for processing the data representing the crossroads being scanned. do.
