Abstract: A data processing device wherein messages are inputted for a plurality of recipients. The recipients' names are displayed along with the number of messages. When a message is inputted for a new recipient, the recipient's name as well as the message are automatically stored. In the event the recipient's name has already been stored only the message is stored.

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 system capable of processing data in a plurality of modes including an input/edit mode is disclosed. The system includes a data name memory, start address memory and edit condition memory wherein the status of data being processed in the input/edit mode is stored when processing in the input/edit mode is interrupted to enable processing in a different mode and based upon which the system resumes processing in the input/edit mode.

Abstract: In a printing device, it is possible to automatically place a print head on the peripheral positions of the print area without actual printing operation.By employing the above arrangement, an operator can exactly determine a proper size of print sheet for the text to be printed, with no waste of sheet and printing time.

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: A word processor with display screen having a search and replace function wherein, when the cursor is positioned at the head of a character queue input area on the display screen in the search and replacement mode, a correction key stroke causes all the characters displayed in the character queue input area to be erased, so the character queues of the SEARCH and REPLACE WORDS can be easily and efficiently entered and the time required for text memorization and editorial operations by the word processor is reduced. Furthermore, the accuracy and ease of conversion of words or phrases in the text is improved, especially with regard to appropriate conversion between capital and small characters.

Abstract: In a data processing device such as a word processor comprising input means for inputting character data and format data, display means for displaying the input data on a screen, and means for processing the input data and displaying the processed data on the display means, the screen on the display means is separated into a line format area for displaying line format data and other area for displaying the other, and the processing device is provided with means for shifting the data displayed on the line format area relative to the data displayed on the other area.
