Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a dot pin plate set at one end for dots, and a group of dot pins corresponding to the number of rows of dots forming one line of Braille characters, which are slid up and down. A group of solenoids are provided on the machine base, and when energized, the solenoid group disengages from the notch of the braille pin plate due to the force of a spring and allows the solenoid to slide, and the dot pin of the dot pin plate group A pressing punch and a supporting punch, each equipped with an engagement hole that engages with each other, are mounted on a machine so that they sandwich the Braille pin plate group from above and below and move as one, and the pressing village and the point of the dot pin plate group This invention relates to a Braille line printer in which dots are made to appear on Braille paper installed between a pin group and a Braille pin plate group corresponding to a group of non-energized solenoids and an underlay of a Ujimura and a support punch. It was devised to dramatically improve the dot efficiency of Braille by dotting the dots corresponding to one horizontal row of one line of Braille at a time.

Next, to explain this in detail using the example shown in the figure, 1(1,...ln
) is a dot pin plate, and at its upper end there are dot pins 2 (2...2n) for Braille pointing upwards (forward in Figure 3).

Engagement notches 4 (4, . . . , 4n) are bored in the substantially central edge of one side.

Reference numeral 5 denotes a machine stand, and this machine stand is provided with a base plate 6, both side frames 7, 7 erected on the base plate, and located between these side frames 7, 7, respectively. a stop plate 8, a pair of spacing plates 9, 9, a guide plate 10, and a stand positioned approximately at the center of the front and back (in the front-rear direction in FIG. 2) of the stop plate 9 and the guide plate 10. A pair of support plates 11, 1 provided on the board 6

Furthermore, the necks of each of the numerous Braille pin plates 1 (1,...ln) are inserted into the uppermost hole 12 of the stopper plate 8 from below, and the lower parts of each of the braille pin plates 1 (1,...ln) are inserted into the elongated hole 13 of the guide plate 10 from above. A pair of spaced plates are arranged so that the notches 4 (4, to 4n) of adjacent Braille pin plates are positioned in opposite directions and alternate. Between 9 and 9 in the vertical direction (

One end of the point pin plate 1 (1...ln) has a protrusion 21 (21

It is now possible to release the parking operation of the Braille pin plate 1 (1...ln) due to the engagement with the notch 4 (4,...4n) of the dot pin plate 1 (1,...ln). There is.

Reference numerals 25 and 25 are a pair of operating punches, and the forked portions 26 and 26 formed at one end of each are connected to the pins 2 of the connecting villages 16 and 16.
7 and 27, respectively, so that the pressure village 14 and the support punch 15 can be moved up and down integrally through the connecting punches 16 and 16 by the operation of the operating punches 5 and 25.

Figures 2, 3 and 7 show the normal state, in which the pressure village 14 and the support village 15 are positioned at the uppermost position (at the front in Figures 3 and 7) using the operating punches 25, 25. Then, use the support punch 15 to push the dot pin plate 1 (1,...ln) onto its stepped portion 3 (

After selectively energizing the sole and the node and releasing the temporary parking of the Braille pin board by the parking punch as described above, the operating punch 2
5 and 25, the pressure plate 14 and the bearing punch 15 are moved downward (in the direction not shown in FIG. Even if the pressure point 14 moves downward in the direction indicated by the arrow in FIG. Braille pin board 1 that does not work
Since the dot pin 2 is slightly protruded from the upper surface of the stop plate 8 as described above, the downward movement of the press 14 causes the dot pin 2 to be inserted through the Braille paper 29 into the receiving hole 28.
By engaging with the Braille paper 29, a dot is placed on the Braille paper 29.

(Figures 8 and 9 show the operating state.) Next, the braille pin plate 1 is moved back by the return movement of the actuating punches 25, 25, and then the selective excitation of the solenoid 19 is released. According to
Each part operates in the opposite direction to that described above to return to its normal state. After dotting, the Braille paper 29 is fed in a predetermined direction and the above-mentioned operations are repeated one after another, thereby making it possible to dot one horizontal row and one column of the Braille characters one after another. As described above, according to the Braille line printer of the present invention, after selectively energizing the solenoid, the pressure punch and the support punch are operated to print one row of dots in one horizontal line forming the basis of Braille on the Braille paper. Not only is it extremely efficient because it allows dots to be placed all at once, but its structure is such that the loquat plate, which is not selectively energized, is fixed to the machine base by the tension of a spring. It has many benefits, such as being sure to hit the ball.

In the figure, numeral 30 indicates Braille dotted on the Braille paper.
