A word processor having an output function for adding margin text, such as a heading or a footing to a main text, includes main text editor, margin text editor, print controller, display device and display device controller. The display controller displays the main text and the margin text simultaneously on the display device in the same form as they are printed out on a paper. Thus, the margin text can be set without printing while an operator confirms its print form.

Word processor with a margin text edit function

The present invention relates to a printing apparatus such as a typewriter which prints data from an inputting means on a printing medium. In the case of the normal printing apparatus, a feed amount setting means is installed which sets the amount of feed of line feeding or space feeding for relatively moving a printing head and the printing medium, and for the line feeding or for the space feeding, a desired one among about four kinds of amounts of feed is required to be selected. This printing apparatus comprises a unit feed amount selecting means for selecting a unit amount of feed, a feed amount setting means which selects a coefficient to multiply the unit amount of feed selected by this unit feed amount selecting means and sets the actual amount of feed, and a controlling means controlling a feeding mechanism so that the amount of feed of the relative movement is the amount of feed set by the feed amount setting means. Lamps are lit to indicate the feed amount.

A printing apparatus comprising a print wheel having a multiplicity type elements, and a detecting unit for detecting angular positions of the print wheel including its fixed home position. The apparatus further comprises a control unit which includes a first counter which stores data representative of an angular distance of a type element currently located at the printing position as measured from the home position, and a second counter which stores data representative of an angular position of a type element designated by a print signal. Both counters are operated as they receive position signals from the detecting unit. The control unit is so arranged that in the event of an unexpected rotation of a wheel driving rotary shaft which is not a result of the actuation of a wheel driving motor in response to the print signal, the print wheel is first reset to the home position before it is rotated to bring a designated type element to the printing position, whereby chances for printing errors due to such unexpected rotation are eliminated. A method for controlling to prevent the printing errors is also disclosed.
