ABSTRACT:
A pen-recording apparatus capable of recording not only regular letters, but also special letters each of which consists of the regular letters slightly shifted relative to each other. The apparatus comprises a platen supported rotatably to hold a sheet of paper, a pen movable along the platen, a platen drive to rotate the platen, and a pen drive to move the pen. The apparatus further comprises a primary control device for controlling the platen and pen drives to cause movements of the pen and the sheet of paper relative to each other for writing on the paper a first element which is the regular letter, and a secondary control device for controlling the drives, after completion of writing of the first element, to bring the pen to a starting position of a second element which is the same regular letter as the first element, the starting position of the second element being shifted by a predetermined distance from that of the first element in a selected direction.
