Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a general-purpose Japanese typewriter typewriter, and particularly relates to a Kanji code typewriter that prints characters and codes corresponding to the characters on both the front and back sides of printing paper.

Conventionally, in this type of device, in order to input the printed characters into an optical character reader, etc., the code corresponding to the character was stored integrally with the typeface and printed on the same side of the printing paper. It had become.

Therefore, although the printing mechanism used in conventional Japanese typewriters can be used, uneven printing tends to occur during printing, and clear printing cannot be achieved.

It also had drawbacks such as poor reliability due to abrasion of the type.

In order to eliminate these drawbacks, the present invention includes a printing mechanism that uses a vertical line of wire dot heads in addition to the character printing mechanism, and uses a solenoid magnet to move the wire dot head horizontally by one character. The wire dot head is characterized by being configured such that a plurality of rows of codes corresponding to one character are printed, and the wire dot head is returned by the amount of movement after printing the code corresponding to one character, and will be described in detail below. .

1 and 2 show one embodiment of the present invention, with FIG. 1 being a plan view thereof and FIG. 2 being a side view thereof.

In FIGS. 1 and 2, 1 is a wire dot head;
2 is a solenoid magnet, 3 is a reset splinter,
4 is the code printing platen, 5 is the ribbon, 6 is the rotation center,
7 is a printing paper, 8 is a feed roller, 9 is a pressure roller, 10 is a platen, 11 is a type bar, and 12 is a type.

FIG. 3 shows an example of a code printed by the code printing device of this embodiment, and 13 consisting of 13a to 13t is a dot code.

The type bar 11 and the wire dot head 1 have the same base, and the printing position relationship is such that the printing center is the printing line pitch and (2n+1)S/2 (n is an integer, in this case 4).
) and platen 10 and code printing platen 4.
are arranged on opposite sides of the printing paper 7.

In this configuration, character printing is performed by picking up the type 12 with the type bar 11, and at the same time, printing is performed by the wire dot head lK for printing the code corresponding to the character.

In this embodiment, the wire dot head 1 is a head with five wires in one vertical row, and the wire dot head 101 shown in FIG.
The dotted lines indicate the mounting positions of the wires in one vertical row, and in order to print the dot code 13 as shown in FIG. When the suction is finished, the reset spring 3 returns to its original state.

In this embodiment, when the reset spring 3 is used to return, signals for each row of dot codes 13 are sent to the wire dot head 1. The dot code 13013 is printed with 13p to 13t of the dot code 13 in the fourth column.

Generally, in Japanese typewriters, the front printing mechanism is spaced after printing one character.

In this embodiment, the code printing mechanism is mounted on the same base as the front printing mechanism, so when character printing is completed, the code printing mechanism is moss-based together with the spacing of the front printing mechanism, as described above. characters can be printed, and multiple characters can be printed.

As explained above, in this embodiment, the dot code is printed using a wire dot head on a surface different from the character printing surface.
Advantages include a larger space for code printing, clearer printing, and the ability to simplify the structure of the code printing mechanism because the code printing mechanism is mounted on the same base as the front printing mechanism. There is.

In this example, each row of dot codes was printed when the wire dot head was suctioned by a solenoid magnet and then returned to its original state by a reset spring, but the same effect could be obtained by printing each row of dot codes when suctioned by a solenoid magnet. I can do it.

Further, a rotary solenoid or a motor can be used instead of the linear solenoid magnet to move the wire dot head.

Furthermore, it goes without saying that the same effect can be obtained even if the wire dot head is linearly slid rather than rotated.

As described above in detail with the embodiments, the present invention improves the quality of code printing because characters and codes corresponding to the characters are printed on both the front and back sides of printing paper. There is an advantage that the code printing mechanism can be constructed economically because the number of wire dots for printing by moving the code laterally by one character is only required for one row.

Claims (1)

[Claims] 1. In a Japanese typewriter-style kanji code typewriter in which ordinary characters and codes corresponding to the characters are printed on both the front and back sides of printing paper, ordinary characters are printed on the front side of the printing paper in the general-purpose Japanese typewriter format, At the same time as printing the one character, multiple lines of codes corresponding to the one character are printed on the back side of the printing paper by moving one vertical line of wire dot heads horizontally by one character, and the one character is printed. A kanji character comprising: a mechanism for returning the wire dot head by the amount of movement after printing a code; and a mechanism for spacing both printing mechanism parts after printing the normal character and the code. code typewriter.
