Optoelectronic data entry means having plurality of control means to direct part of radiation in channel from radiation source to output channel

摘要: An optoelectronic data entry means which employs radiation and radiation-responsive elements as a of converting information from manually entered form to electrical signal form. A plurality are mounted in chambers housing row-and-column arrangement. communication channels output disposed generally planar orientation the housing. The provide access source disposed, paths said detectors capable signals. Beam splitting devices on inner ends effective, upon selective operation elements, deflect portion admitted through into for detection by corresponding detectors, while permitting another pass beam splitters possible interception splitter element associated with same channel. Two arrangements disclosed, one includes mechanical encoding input information.
