摘要： A data entry and processing system providing for simple two stroke entry of numerous auxiliary alpha-numeric data in addition to the single stroke entry of numeric data, using conventional data entry keys. The key array includes a set of radial direction indicator keys that are used with the conventional keys to select and enter a given alpha-numeric data item. An LCD display, a pre-programed micro-processor and other electronic components are included to display the data entries, as well as to convert entered data signals to the necessary DTMF tones for telecommunication or ASCII codes for computer data entries. The system is simple for use by ordinary users, and all electronic components are standard, miniscule in size, small in number, low in power need and low in cost. It is particularly adaptable for miniaturized device application.
