Abstract: A data processor for speedier processing of input data includes a data processing system for executing a text editing process and a text printing process by the time slice method and a preference control unit for selecting between the above processes. When data is entered into the processor, the entering process or text editing process is generally preferred to the text printing process. Therefore, no delay occurs in inputting data through a keyboard from data entry to its display. If desired, it is possible to prefer the text printing process to the text editing process.

Abstract: A data processing apparatus having an input device for entering data, and a timer connected to the input device for measuring a predetermined time duration during which a data entry operation through the input device is interrupted. The apparatus is provided with a display, buzzer or any visual, audio or optical device for providing information associated with the data entry operation interrupted, when the timer has measured the predetermined time duration. The associated information may be a candidate word or words to be substituted for a word in the process of entry into an electronic typewriter or a word processor. The associated information may also be information such as addresses or telephone numbers of persons or companies whose data have been entered prior to the data input interruption. Further, the associated information may be a message prompting the operator to enter a specific kind of data, or information indicative of an operation that should be performed after the interruption of data entry.

Abstract: A word processor with a merge print function which permits an insertion data file to be easily formed without troublesome operations an insertion data field can be adaptively expanded or has the capability to adaptively expand or contract an insertion data field to cope with either longer or shorter lengths of input data. The expansion or contraction is executed either manually by a specific key operation, or automatically according to the data length.

Abstract: An information processing apparatus includes input means for inputting data such as characters or symbols, a display device for displaying the input data successively, an information memory for storing information corresponding to the input data, retrieving means for retrieving information corresponding to the input data from the information memory, display means for displaying information which is retrieved by the retrieving means to a position corresponding to a position at which the input data is displayed in the display device, and instruction means for indicating the completion of input of at least one input data, instructing the retrieving means to conduct a processing for retrieving information concerning the input data, and instructing the display means to conduct a processing for displaying the information retrieved by the retrieving means.
