The latter is called a subscript.

In conventional printers with such scripting capabilities, the l word is typically a standard M! word consisting of 7 bins/parity bits. ICII: Character information is composed of f-codes, and there is a lack of bits for distinguishing attributes of character information such as script instructions.

In the case of script printing, the input information is composed of the character information of the L word [print information] and the L word indicating the script printing instruction corresponding to the attribute of the character information, and this input information is supplied to the print control means. I was printing out the script for that portrait. Therefore, the only way to determine whether or not that character information is to be scripted is to check the word that indicates the attribute of the next character information, which inevitably makes the above-mentioned control means complicated. Ta.

An object of the present invention is to eliminate the above-mentioned drawbacks, add instruction mark tubes for instructing script printing to both ends of a character string to be printed as input information, and control platen rotation in response to the instruction marks. Accordingly, it is an object of the present invention to provide a printing device control method tm that enables script printing using a simple control means.

From the source, the logic values @l' of the antgames l to U are supplied.

Next, the operation of the apparatus shown in FIG. 1 will be explained.

- As an example, let us consider the case of performing a script printing tube shown in Sections II and K. In this case, Section-II (
B) As shown in K, an input information tube is sequentially supplied from the input device I with marks 1↑@ added to both ends of the character string to be printed by script + Jm to indicate script printing.

Therefore, when printing 7k"!""sm' as in No. 8 (A), 1. First, the character information indicating @x" is sent from the input device I. This character information be received. The type and printing hammer control device Ω selects the type 1x” corresponding to the information, drives and controls the type and printing hammer mechanism W/H via the AND gate υ, and prints 1 character @x1. In response to the end of the printing operation of the mechanism W/H.

The middle carriage controller C/ controls the drive of the carriage machine @CG1 via the antagonist/1, and moves it to the right by one column. Note that the carriage control device C/, as in the conventional case, controls the carriage control device III according to the carriage return information and space information CK supplied from the input device I.
He also performs ICG drive control.

Next, specify a specific marker to instruct script printing from the input device I! 1↑”, the corresponding information (instruction code) a is supplied.
The logical value (level value) of Toma output goes from @O# in the 111th period state to @l''!L@.The logical value of this 7th sound 1 F4Tsub 1/1 @6 @ to HL @ of @/II In response, control value 4# is sent from script control device C# to platen mechanism P.

Next, the character string @1÷J sequentially supplied from input device I
The input information indicating ``tube'' is printed under the same @ control as in the case of printing the above-mentioned character @X. Follow, srs.

So, the result printed so far is 2X.

Script printing can be obtained as requested.

Next, when the information corresponding to the specific mark 1↑” is provided again from the input II “11!”
The output logic value of is inverted from 11m to 10". The script control device CII responds to the inversion of this 7-lip F/F by sending a signal with a value of 10" to each ANDG).
-AJ K At the same time as 1 is supplied, a control signal is supplied to the platen a1%P'l'', and the platen is rotated 34 lines in the forward direction and returned to its original position.

In other words, the information on the specific mark 1↑'' supplied to the M-th a-th mark is treated as the completion script printing end instruction information, and the platen mechanism 1! is returned to its original position before printing the script. The input information for the character 1-'' supplied from device I is.

In the same way as in the above-mentioned case of printing the character 'x' in the script print stroke, it is printed on the same line.In this way, the letter 'x' as shown in
A printing result of 1-°' is obtained. In addition, the power control device CJ is a λ blade device as before! In response to information 4 indicating the line field supplied from.

It is also possible to drive and control the 1st axis y@@p'r to move the platen 17 rows B@ in the positive direction.

It is clear that this example can be easily applied not only to the printing of super scripts such as 5 x -1 and 1-'' as described above, but also to the printing of napsticks such as @X and O@. If a certain 0 is printed, for example @lll0", %
Configure the input information as ``H↓ko↓ol'', move the platen in the forward direction t>86 with the first specified! - It is only necessary to control it so that it returns to the original position by one turn with @r.

As mentioned above, in the present invention, a character string to be printed by a script is added to both ends of a character string to be inputted with a setting value for instructing script printing. Since the platen is controlled in response to the data, script printing can be achieved with a relatively simple control means. In addition, when inputting from a keyboard, conventionally it was necessary to press the key indicating script printing with one hand and type the character command to print the script with the other hand, but the present invention has been improved. According to 1, input can be made in the same manner as normal character kukata, so mathematical expressions can be entered with extremely simple operations, thereby making typing work easier. Furthermore, when using the memory am, it is also possible to efficiently store documents containing many numbers, formulas, etc.
