Abstract: An electronic typewriter including a memory storing therein text data which is printed as printing signals are produced. The electronic typewriter enables the operator to pass judgment as to whether printing can be performed on a portion of a sheet of paper between the last printed line and the trailing end of the sheet when the sheet of paper has been set in the typewriter in a usual manner, so that printing can be continued when it is possible to do so. When it is judged that it is impossible to continue printing due to a lack of space, printing is stopped and the existence of the condition of "paper empty" is indicated, prompting the operator to insert a new sheet of paper.

Abstract: An electronic typewriter with data storage and editing capability having a keyboard for entering printing data including character data representative of a text, a text memory for storing the character data from the keyboard, and a printing assembly for printing the stored text according to the printing data. The typewriter comprises a first control device for printing all lines of characters of the text stored in the text memory, a designating device for designating in an editing mode a group of character data corresponding to a desired line of characters of the stored text, a second control device for printing only the desired single line of characters designated by the designating device, and a third control device for printing the designated and all subsequent lines of the stored text.

Abstract: An electronic typewriter provided with a display unit giving visual display of data in a number of positions of characters shorter in length than one line of characters printed on a sheet of paper which includes a cursor for indicating the next following position of data input. The cursor may be shifted out of the display unit when necessary, and when the data imputted to the last position in the display unit is dead key data, the position of the dead key data is indicated by the cursor, so that the display unit can display data greater by one character than display units of the prior art.

Abstract: An electronic typewriter equipped with a text memory for storing data including character data representing characters to be printed, and format data for arranging the characters to be printed, comprising a line deleting device for deleting data for a line stored in the text memory, a detector for detecting the format data associated with the line to be deleted, and a device for saving the detected format data so that the format data are not deleted from the text memory during a line deleting operation.
