Abstract
A hand held scanner having recording capabilities is provided. The invention comprises a scanner which reads bar codes, converts the codes to electrical signals, which are then relayed to a palm size data processing unit. The data processing unit contains signal synthesizing, memory, recording, playback and erasure means. The device has six operating modes: the identification or I.D. mode during which scanning takes place and an audible output is generated; memo mode during which data (some of which may not relate to a particular object) may be input into, deleted from or replayed by the device; search mode during which a sequentially audible listing of recorded information is played back; memory mode during which the amount of remaining available memory is audibly displayed; date/time mode during which the current day and time are audibly displayed; and help mode which contains a brief overview of the device's functions. A record button permits verbal input during the I.D. mode and memo mode. An erase button deletes voice input data during the I.D., search, and memo modes. The previous and next buttons move to the desired message during the search and memo modes. A removable flash memory stores recorded information, and a speaker, microphone, headphone jack, and on/off and volume control systems are also provided.
