Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a key-controlled printing device, and more particularly to a printing device that can print frame lines only by key operations.

Conventionally, when trying to write patterns other than letters and numbers on printing paper, such as frame lines, there was no other way than to apply a ruler and write with a ballpoint pen or the like. Therefore, if it protrudes, dirt etc. are likely to occur.

The present invention has been made in view of the above-mentioned difficulties, and allows frame line printing to be performed with σf function by selectively using horizontal line type and vertical line type by key operation.

Furthermore, the corners of the frame lines can also be printed accurately.

fft, Figure 1 is a diagram showing a part of an example of a print head according to the present invention, for example, an example of a petal type type wheel.

In addition to normal type letters CA, the printing type includes at least vertical line type characters CV, horizontal line type characters CHI, and CH2, and printing is performed using vertical lines and horizontal lines as shown in FIGS. 2 and 3. CHI is placed at the center of the type section.

It is used to print a negative sign (minus) as shown in the first row and column ■ of Figure 2, and CH2 is provided on the side of the type part, and the characters are Used for underline printing on the lower sides of E, F, G, and H. Cv is shown in Figure 2 1
~3rd row, 6th to 11th rows, Φth column, Figure 3, 6th to 11th rows, ■th column,
It is used for printing various vertical lines as shown in the 8th to 10th row (■), column (■), row 12 (■), and column (■). As shown in FIGS. 2 and 3, the printing apparatus of this embodiment does not require any special ruler or writing implement, and allows vertical and horizontal lines to be selected only by key operations and printing operations.

Furthermore, in the case of frame line printing in FIG. 2, the frame in the 3rd row and ■ column is blank by the printing pitch, making it difficult to see. Also, the frame in the 5th row and ■ column extends beyond the frame and is difficult to see. Also, 3 rows Ll E, F, G, H
When enclosing a frame using the Angoo line at the bottom of the letters E and F.

It's too close to G and H so it's hard to see.

The present invention can improve this, and FIG. 4 is a block diagram of an example thereof. In the figure, KB is a keyboard, which has a vertical line printing instruction key KV, a horizontal line printing instruction key KH, a continuous printing instruction key KR, a key KP that gives an instruction to change the printing pitch or paper feed pitch, for example, to darning, and keys KP and KH. It is equipped with a shift key KS and other well-known character, number keys, control keys, etc. for everyday use.

CPU is the central processing unit, CD is the control circuit for the carry and paper drive motor CM, and PD is the control circuit for the paper feed motor PM.
CA is a carriage on which the type wheel KH shown in Fig. 1 is mounted, and P is a printing paper. To print vertical lines as shown in FIGS. 2 and 3, a well-known control key such as a right or left key is pressed on the gear ridge CA. The CPU detects this, activates the drive circuit CD, sends the right feed signal IF or the left feed signal 1B to the output line 11 or j2, and outputs the OR gate oR.
The carriage drive motor CM is rotated in the forward or reverse direction via t, and the carriage CA is moved by one print pinch at a time to set it at a predetermined position, for example, the vertical position of the ①th column. Next, when the key KV is pressed, the flip-flop FV in the CPU is set and this is stored, as well as for example 6 on the printing paper P.
A vertical line "rl" is printed at the digit position in the row and column.

After that, when the repeat key KR is pressed, the CPU detects this, sends a paper feed signal IF to the output line J15 of the control circuit FD, drives the paper feed motor PM via the OR gate OR2, and moves the paper feed roller RO one line. Rotate by the paper feed pitch to feed the printing paper P one line.

When the repeat key KR is further pressed, a vertical line "1" is printed at the turn position of the next row since the flip-flop FV remains set. Similarly, each time the key KR is pressed, a vertical line "1" continues to be printed at the same digit position. Furthermore, even if one line is overprinted and extends beyond the printed line, it can be easily erased using a well-known correction ribbon with just a key operation.

Next, press the shift] key KS to print a horizontal line "-" and then press the key KH.
Upon detection of H, flip-flop FV is reset.

Also, change gear ridge CA to V! 11'! Uchi 0 column 1]
If it is printed at this position, it will be printed as shown in Figure 2, row 5, column 1. To avoid this, press the shift key KS and then press the key KP. The CPU detects this, sends a right half feed signal 34F to the output line 13 of the control circuit CD, and moves the carriage CA rightward by the station printing pitch.

As a result, gear ridge CA is positioned between 0th row 1" and 2nd row, and by pressing key KH, the horizontal line
"-" is printed between the 5th row and the 11th column in FIG. 3, and the correct frame line printing is performed.

Also, if the carriage CA is in any other position, press the well-known pack key KA the required number of times.

When the key KP is further pressed, the output line of the control circuit CD becomes 2. The left advance signal IB and the left half advance signal %B are sent out at No. 4, respectively, so that the carriage CA can be stopped between the 0 column 1.1 and the 0 column 11 as described above. Also keys KV and K
P Furthermore, if you press the key KA as necessary, the 31st yJ8
~10th row, ■, ■ column 1-1, if the vertical line rlJ is moved left and right according to the station printing pitch and printed, the characters dl-d3. inside the determinant are printed. It is possible to print in a well-balanced manner with cl to c3, etc. Furthermore, if a half-pitch feed function such as "double-pitch" is applied to paper feed, the print format will become even more legible. Therefore, the paper feed control circuit FD outputs the output lines 5 to 5j! '8, and a 1-pin 11-day reverse feed signal IFP similar to the control circuit CD.

IBF, 'A pinch forward/reverse feed signals y2FF, and BP can be selectively output.

For example, when the key KP is pressed, the CPU detects this and sends a signal to the output line 17 of the control circuit FD. The FP is sent out, and the printing paper P is fed by the i-pitch. Further, when the shift key KS is pressed and then the key KP is pressed, the carriage CA is moved to the right by the station printing pitch by the output line No. 3 of the control circuit CD, as described above. From this state, by pressing the well-known character keys E, F, G, and H, the characters E, F, G, and H can be printed in the middle positions of each row and each column in rows 6 and 7 of Figure 3. This will maintain good balance with the top and left border lines. Further, by this pitch feeding of the printing paper P, the horizontal line "-" in "row 6 column 1" in FIG. This has been made possible by feeding the printing paper P by the pitch even though the horizontal line type character "-" is engraved on the lower side of the type part as shown in FIG.

Further, the vertical line type character "1" is not limited to frame line printing, but can be used for various purposes such as dividing the year, month, and day, as shown in row 9, column 6, column 1 in FIG. 3.

As described above, the present invention provides a print format that is extremely easy to read by providing vertical line type, horizontal line type, carriage pitch feed, printing paper width pitch feed, and a group of control keys for these. It is easier to read than the matrix format and does not strain the eyes, which is extremely preferable.
