Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a print control device, and more particularly to a print control device suitable for printing and recording required characters or symbols by selecting points in a matrix.

FIG. 1 shows a perspective view of a handy typewriter suitable for applying the printing control device of this embodiment, in which 2 is the main body of the device, 4 is a key for selecting characters or symbols to be printed; Reference numeral 6 denotes a long heat-sensitive recording paper for printing and recording by thermal means, and 8 indicates characters or symbols recorded on the recording paper 6 by a printing means (not shown) provided in the main body 2. Each figure shows a transparent acrylic plate for magnification and reading.

FIG. 2 shows a printing mechanism for use in a handheld typewriter as described above.

In the figure, 10 is a recording paper roll for supplying the thermal recording paper 6, 12 is a thermal head for performing thermal recording on the thermal recording paper 6, and 14u is a head base for holding the thermal head; i6H A spring that presses the thermal head 12 onto the thermal recording paper 6.

18 is a feed roller that rotates in the direction of arrow X and feeds the thermal recording paper 6 in the direction of arrow y; 20 and 22 are used to guide the thermal recording paper 6 from the recording paper roll 10 to the thermal head 12 section; guide roller.

24 is connected to the feed roller 18 via gears 26 and 28.
This figure shows a stepping motor that intermittently drives 1 in the direction of arrow X.

In the above configuration, the thermal head 12 is the third button.
As shown in the figure, seven heating elements 30A to 30G are arranged in a line perpendicular to the feeding direction y of the recording paper 6, and as shown in FIG.
At the time of intermittent stop corresponding to each snap during rotation of 4 by 5 steps, that is, 5 columns P1 to P5 Vc
The heating elements 30A to 3 are placed at the corresponding position on the recording paper 6.
By selectively energizing 0G and coloring the points on the thermal recording paper 6 that correspond to the energized heating elements, 7×5
A single character formed by IJ can be printed without printing.

That is, in the printing control device of the present invention, the 7×5 point matrix is divided in time, and after printing the first episode P1, the recording paper 6 is advanced one step, and then the second Seven heating elements 30A are used to print Yu1NaiP2.
~35 of 7x5 with thermal head 12 with 30G
The desired printed character is obtained by selecting a matrix of points.

To explain the above in more detail, as is clear from the timing chart shown in FIG. is performed, and then a feed control signal S1 for one-step advancement is applied to the stepping motor 24 to advance the recording paper 6 by one step, and then the recording paper 6 is advanced by one step.
After printing the fifth column P5, repeat the operation of 1 to advance the recording paper 6 by one step using the feed control signal S5. By applying the signal S6 for one step increment without inhibiting the print control signal that should be given to the printer and performing printing,
Recording paper 6 that secures the space between the characters to be recorded next and corresponds to the first column P1 of the next printed character.
The print head 12 is placed in the upper position to finish printing the character (■).

By repeating the printing as described above, it is possible to obtain a print as shown in FIG. 6.

Furthermore, the print control signal and feed control signal as shown in the fifth figure can be easily obtained by using a ring counter as shown in the seventh figure.

In the circuit shown in FIG. 7, all flip-flops F
The outputs Q of all the inverters 1 to F12 are tt and u, so the outputs of all the inverters 1 to 1□ are ItO'''.

Therefore, at the D input terminal of flip-flop F1,
oy'' input is applied.

In such a state, if the clock pulse 11 given by AND logic with the print signal PS is manually applied,
The Q output of the flip-flop F1 becomes 0'', and this 110'' output is applied to the D input terminal of the next flip-flop F2, and tt from the inverter ■1.
ljj output is made, and therefore a print control signal is obtained which instructs printing of the first row P1.

Subsequently, when the next clock signal , is input, the Q output of flip-flop F2 becomes O'', and the ``0'' output is applied to the D input terminal of the next flip-flop F2, as well as from inverter ■2. Therefore, in order to make the print head 12 corresponding to the first column P1K on the recording paper 6 correspond to the second column P2, the recording paper 6
A feed control signal S1 is obtained for stepping the column one column out of the column.

Below, flip-flops F3 to F12 are clock TM
Since the tt Opp output is performed in synchronization with P, as a result, as shown in Fig. 5, each column P1 to P
The print control signal to be obtained from the flip-flop F11 after alternately obtaining the print control signal corresponding to 5 and the feed control signal 81 to S5 for advancing the recording paper 6 by one column in order to change the column. In addition, it is possible to obtain a feed control signal S6 for advancing the recording paper 6 one column out of the column in order to obtain more space with the next printed character.

The print control signal and feed control signal obtained as described above are sent to the print control signal terminal PP through an OR gate, respectively.
and are obtained alternately through each terminal of the feed control signal terminal SS.

With the configuration as described above, printing elements corresponding to all the points of the matrix are provided even when printing and recording the required characters or symbols by selecting the points in the matrix. It is possible to obtain a new printing control device that eliminates the need for printing using the number of printing elements corresponding to the number of printing elements in one column, and can therefore constitute an economically superior printing device with a simple structure. be.

In the above embodiment, only the case of thermal printing was described, but the present invention applies to a wire.

It can also be applied to other printing devices such as printers, ink jet printers, etc., and its usefulness is extremely limited.
