ABSTRACT:
An electronic typewriter having a carriage which is automatically returned upon entering of space data through one operation of a space key on a keyboard, which space data is to be executed within an automatic-carriage-return zone which consists of a desired number of columns just before or up to the right-hand margin of the line of printing, comprising: a check device for checking whether printing data entered immediately after space data which causes an automatic carriage return is another space data or not; a timer which is started upon entering of the carriage-return space data; and a control device for comparing data of a time which is given by the timer when the above-indicated another space data is entered, with data of a predetermined reference time, and thereby executing the above-indicated another space data if the data of the time which is given by the timer is found to be beyond the data of the reference time, the control device neglecting the above another space data if the data of the time of the timer is not beyond the reference time.
