Abstract: Part of a first signal path for amplifying a signal includes circuits for detecting a signal, and a second signal path connected to an input portion of the first signal path includes circuits for detecting the signal. A signal strength detector circuit adds outputs from the respective detector circuits in the first and second signal paths. The first signal path has a function of expanding the dynamic range in a smaller signal region as compared with the second signal path, while the second signal path has a function of expanding the dynamic range in a larger signal region as compared with the first signal path. When a radio transmitted output is variably controlled in a radio transmitter section based on a field strength detection output for a received signal, the transmitted output is optimized, resulting in minimizing consumed power and unnecessary radiation of radio waves.

Abstract: The present invention relates to an optical reader for scanning a surface to be scanned by using information beam ray such as laser beam ray and optically reading a recorded information such as bar code recorded in the surface to be scanned. The optical reader is constituted such that optical beam emitted from a light source is reflected on a first rotary multiface mirror to scan on a surface to be scanned, and information beam reflected on the surface to be scanned is reflected on a second rotary multiface mirror to guide to an opto-electric transforming means. A scanning optical path for permitting the optical beam from the light source to pass therealong is formed independently from a reflecting optical path for permitting the information beam from the surface to be scanned to pass therealong.
