摘要： PURPOSE:To reduce the number of key operations necessary to print special letters, by a method wherein, after a given symbol is inputted, a type head is automatically positioned at a printing position thereof. CONSTITUTION:Also in the case of the dead code for printing special letters, printing takes place by sending out to a system (printer) in the same manner as in the case of other code, and a printing head moves by one space to a subsequent printing position. In the case of the dead code, a ROM15 outputs a response signal, and triggers a monomulti-vibrator 17 via a gate 16. A monomulti-vibrator 18 triggers at a rear end of an output wave shape of the monomulti-vibrator 17, and drives a coil of a reed relay 19 with said output. A relay 19 turns on a switch connected in parallel to a back space key (BSP) in a key matrix 10 by means of said drive signal, and the printing head in the system is moved back by one space.

摘要： PURPOSE:To facilitate correction of mistyping by provision of a ribbon universal lever for operating a ribbon take-up device which operates simultaneously with the operation of a typing key, a back spacing key capable of returning a platen on a carriage to the position of mistyping, and a mistyping correction key. CONSTITUTION:Upon mistyping, a back spacing key 26 is depressed. With a mistyping correction key 37 dr depressed, a link 50 moves to project a projection portion 60 of a lever 61 into the rotational locus of a projection piece 16 of a lever having a holding claw for an escapement mechanism 10 through a steel wire 63, to hold the mechanism 10 in off-operation condition. On the other hand, the depression of the key 37 rotates an arm piece 40 counterclockwise through the link 50, an oscillating piece 56, and the like to raise a ribbon holder piece 43, thereby holding a white ribbon portion 49' at the level of a mistyped character K1. With a mistyped key depressed, the mistyped character is eliminated by typing through the white ribbon portion.
