Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a simple Braille typewriter that prints Braille characters for the blind on paper in indentations.

``Conventional Technology J'' The conventional small and lightweight Braille typewriter is
As shown in FIGS. 7 and 8, the front and rear 2 parts on the main body 3 on which the paper 2 is placed have a paper feed guide l on a part thereof.
A printing mechanism section 5 is provided between the rows of guide bars 4 to be slidable left and right along the surface of the guide bars, and is movable laterally on the paper 2. A plurality of pins (not shown) that can be pressed down in accordance with the arrangement and print each dot of Braille on the paper 2 concavely, and a blank body 3 on which the paper facing the plurality of pins is placed. In preparation for this, there is a printing plate 7 on the surface of which recesses 6 into which the lower ends of the plurality of pins are pushed are provided at regular pitches, and a printing plate 7 on the left and right sides of the printing mechanism 5 following the arrangement of the fingers of a hand. a plurality of key levers 8, each of which is arranged in front and back so as to be able to be pushed down in the direction of the paper, and a plurality of key levers 8, each of which has its parts protruding outward from the printing mechanism part and can be pressed down; and the printing mechanism part 5. A return mechanism (not shown) using a coil spring or the like that automatically raises and returns each of the plurality of key levers 8, each pin, and each of the spacer keys 9, which is provided so as to be able to be pushed down when the key levers 8 and the spacer keys 9 are pressed forward. ), and every time one of the plurality of key levers 8 or spacer keys 9 is moved up or down, the printing mechanism section 5 is moved along the surface of the guide bar 4 of the main body.
A feeding mechanism IO that moves the upper part rightward and leftward at a constant pitch so as to be able to return, and a paper 2 portion printed using the printing mechanism section 5 are transferred to the main body together with the paper feeding guide l on the main body and the printing mechanism section 5. Rotating shaft 1L on the left side of the main unit on 3
It consists of a reversing mechanism 12 that inverts the paper 2 in the left-right direction around the center to expose the printed surface of the paper to the main body 3 so that it can be touched with the fingers. After placing it on a predetermined position on the main body 3 and moving the printing mechanism section 5 to the right end of the river paper 2 along the surface of the guide par 4 on the main body, the plurality of key levers 8 provided on the printing mechanism section 5 are moved. After pressing one or several of them down at the same time with your finger according to the arrangement of Braille characters to be printed indented on the paper 2, or pressing down the spacer key 9 with your finger, press each key lever 8. Or release your finger from the sub-key 9. Then, the midway side wall of each pressed key lever 8 or the head of each predetermined pin provided in the printing mechanism section 5 is pressed down toward the paper, and the lower end of each pin is aligned with the paper 2.
The pins bite into the back side of the paper and push into predetermined depressions 6 on the surface of the printing plate 7 on the main body directly below the paper, and the tips of the pins protrude from the front side of the paper 2 to form convex points constituting Braille characters, and When you release your finger from the depressed key lever 8 and the key lever 8 is automatically raised and returned by the return mechanism, the printing mechanism section 5 moves leftward one pitch at a time on the surface of the guide par 4 by the feeding mechanism 10. After moving or pressing down the spacer key 9, the spacer key is automatically raised and returned by the return mechanism, and the printing mechanism section 5 simply moves the paper 2 along the surface of the guide bar 4. IO
By repeating the above operations one by one, the paper 2 inserted in the paper feed guide i on the main body is moved one pitch to the left from the right edge of the paper at regular pitches. Inverted Braille characters, which are normal Braille characters arranged horizontally in reverse, can be printed indented with an appropriate space left in the middle.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional Braille typewriter, while printing convex dots constituting Braille on the front surface of the paper 2 from the back surface of the paper 2 using the Braille typewriter, When checking whether each convex dot of Braille is printed accurately on the surface without any errors,
As shown in FIG. 8, the reversing mechanism 12 is operated and the printing mechanism section 5 is used to transfer the paper 2 with concave printing using the paper feeding guide I on the main body and the printing mechanism section 5, as well as a circuit provided on the left side of the main body. The surface of the paper 2 is exposed to the outside of the main body 3 so that it can be touched with the finger by inverting the paper 2 in the left-right direction around the moving axis l1, and the printed convex points on the exposed surface of the paper 2 are touched with the finger to judge whether the paper is good or bad. Because of this structure, with the conventional Braille typewriter, Braille had to be printed indented on the paper 2 from the right edge of the paper to the left, in a left-to-right manner, which is the opposite of normal. As shown in Figure 9, two rows of left and right rows of upper and lower 3
In the case where 6-dot Braille characters consisting of various combinations of convex dots are to be printed concavely, if the structure of the printing mechanism section 5 is to be simplified, the paper in the printing mechanism section 5 will inevitably be Each convex point of the 6-point Braille is printed concavely on 2, vertically on the left and right 2
Push down the heads of each of the six pins, which are arranged vertically in rows, three at a time. The arrangement of the key levers 8 is arranged to follow the arrangement of the six pins in the printing mechanism, and each of the short key levers 8a at the front left and right of the printing mechanism is arranged at the six points shown in FIG. The convex points e and r on the left and right of the bottom line of the character are used as key levers for printing concave prints on the surface of the paper 2 from the back side of the paper, and the medium-sized key levers 8b at the middle of the left and right sides of the printing mechanism section 5 are used as six-point points. Each convex point on the left and right of the middle line of the character C. d is a key lever that performs concave printing on the front surface of the paper 2 from the back side of the paper, and the long key levers 8c at the left and right ends of the printing mechanism section 5 are used as the key levers 8c for concave printing on the front side of the paper 2 from the back side of the paper. The key lever had to be configured to print concavely on the front side of the paper 2 from the back side of the paper.

However, from a normal human sense, this Braille typewriter is configured so that Braille can be written on the paper 2 from the right, and the left and right key levers 8 of the printing mechanism 5 are
The short key levers 8a at the front are used to print convex dots a and b on the left and right at the top of the Braille indented on the paper 2, and the medium length key levers 8b at the middle are used to mark the middle of the Braille. The convex points c and d on the left and right sides of the line are printed concavely on the paper 2, and each convex point e at the bottom of the braille is printed using the long key lever 8c at the rear end. r to paper 2
Naturally, it would be configured to print concavely on the top, but in the conventional Braille typewriter mentioned above, Braille was configured to be written on the paper 2 from the left, contrary to the usual method, and Since the arrangement of the left and right key levers 8 of the printing mechanism section 5 is opposite to the natural human sense as described above, the conventional Braille typewriter is used to place each convex point constituting the Braille on the paper 2. ．． When printing on the L, the left and right key levers 8 of the printing mechanism are often pressed down by mistake, making it impossible to easily print the convex dots that make up Braille on the paper 2 without making any mistakes. Ta.

Conventionally, Braille is written on the paper 2 from the right side, and convex points constituting the Braille are printed on the paper 2 on the left and right sides of the printing mechanism 5, imitating the natural sense of humans. There is also a Braille typewriter with an array of key levers 8, but this Braille typewriter is constructed using a complicated and large-scale link mechanism, and is large and heavy, making it difficult to carry and use anywhere. It's not possible.

The present invention has been made in view of such conventional problems, and its purpose is to be able to write Braille on the right side of the paper 2, imitating the normal sense of humans, and to write Braille on the left and right sides of the printing mechanism section 5. The key levers 8 that print each convex dot on the paper 2 are arranged to imitate the natural human sense, and each convex dot that makes up Braille can be printed concavely on the paper 2 without any error. Simple structure, small and lightweight, easy to carry and use anywhere.
The purpose is to provide Braille typewriters.
