Electronic appliance e.g. VTR controlling method - employing function dedicated bar codes read by fibre=optic light pen in microprocessor which decodes order and enables selected devices

摘要

An electronic device, such as a video tape recorder is set into a desired, but complex mode, such as automatic recording of a desired programme, by manual scanning with a fibre-optic light pen of one or more bar code groups printed groups upon them for selecting, for example, mode, channel, day of the week, recording start time (including AM or PM), and recording end time. Code signals provided from the scanning instrument are processed in a microprocessor, and included in the VTR to provide control signals to the VTR in response to information contained in the scanned code groups. Alternatively, a combination of an FM receiver and high fidelity audio recorder can be set into an auto record mode or other complex operating mode by scanning of selection cards.
