ABSTRACT:
A self-contained, hand-held, portable code reading and processing system within an elongated tubular housing forms a wand that transduces coded data into selected speech or music. A simple-to-use reading and processing system can be used as part of a learning and activity game. In one form, a scanning guide is hingedly attached to a book. When the guide is folded over a page of the book, a path is created across the coded data to enable children and others to easily scan the coded data with the hand-held wand. A contact switch at or near the scanning end of the system is actuated by the scanning guide to activate the code reading and processing system. An energy-saving power shutdown feature turns off the code reading and processing system when no coded data are scanned in a given time period. The contact switch and the automatic power shutdown system act in concert as a safety system to prevent small children from staring at the light source for prolonged periods of time. Audio data may be provided in the form of a removable memory cartridge, to allow use of the system in a variety of applications.
