Abstract

PURPOSE:To make the reading of printed dot number possible and to make not only character printing but also graph printing possible, by printing graphs in zigzag patterns. CONSTITUTION:For example, 5 types of zigzag patterns corresponding to numerical values of from 1 to 5 are previously prepared. Then, when the construction ratio (%) of input data is expressed graphically, the user can easily read numerical values from their graphical printing because the graphic printing itself is not in block but is formed in staggered menner. That is, the number of dots forming a block can be readily determined based upon the fact that whether the last printed dot of the graph is composed of two or three dots in vertical line.

Description

[Detailed Description of the Invention] (Field) The present invention relates to a printing method, and more specifically, to a character printing method.
This relates to a printing method that allows not only printing but also graph printing.

(Conventional) The printing devices used in conventional recordable calculators are so-called type printers, which can only print numbers and limited symbols, so they can only be used to record calculation results.

However, with the development and spread of electronic printers in recent years, it has become possible to print numbers, letters, symbols, etc. using, for example, a 5x7 dot matrix.
Now, calculation results can be visually appealing to the user not only by printing them in numbers, but also by using graphs.

For example, if you have a 5x7 Dotomado IJ box, see Figure 1 (
By preparing 5'$fi type printing patterns as shown in a), it is possible to express the composition ratio part of the input data in a graph as shown in FIG. 1(b).

However, although the user can grasp the overall trend of the structure of the input data by printing the graph, it is impossible to decipher how many individual pieces of data there are from the blocks printed in the graph. there were.

(Purpose) The present invention was made to solve this problem, and its purpose is to provide a printed butter (Fig. 2 fa) that allows the user to read numerical values from the printed graph. Five types of staggered patterns corresponding to numerical values from 1 to 5 are prepared in advance.

Then, as shown in Figure 2 (b), the composition ratio (correspondence) of the input data
If expressed in a graph, the graph print itself is not in blocks but in a staggered pattern, making it easier for the user to read the numerical value from the graph print.

In other words, in the example, the last printed dot of the graph is vertically 2
The number of dots in one block can be easily determined by dots or six dots.

FIG. 6 is an example of a control block diagram for realizing the above-described printing method, and CGI and CG2 are dot pattern information generators that generate dot pattern information corresponding to dot patterns 1 and 2 in FIG. 2(a). .

AI and A2 are AND gates, OR is an OR gate, PH is a dot print head, cc is a control unit that uses CGI and CG2 alternately according to the graph information to be printed;
5 in figure (a) is separated from each other as one block, and the second block is separated from each other.
Execute graph printing as shown in Figure (b).

(Effects) As described above, according to the present invention, it is possible to provide a printing method that allows a user to print a readable graph of numerical values in a printing device used in a recording type 2 calculator, etc. , it is extremely useful as a device that expands the uses of printing devices and recording calculators using the same.
