Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a typewriter head structure capable of displaying characters and Braille on the same recording medium, and more specifically, the present invention relates to a typewriter head structure capable of displaying characters and Braille on the same recording medium. A typewriter for character braille that is positioned so that the inking means used for printing characters can be easily replaced and the braille engraving head part and the braille inscription receiving part are always in the fixed position. Regarding the head.

Various types of typewriters have been proposed and put into practice as Braille devices for the blind. However, it is extremely difficult for sighted people who are not accustomed to reading Braille to understand the content of the Braille printed by these Braille devices for blind people, and it is difficult for blind people to understand the content. It is extremely difficult to decipher and understand the so-called normal printed text.

Therefore, in order to facilitate written communication between blind and sighted people, it is most preferable to display Braille and characters on the same recording medium. Therefore, as a result of repeated efforts, the inventor of the present invention focused on a dot printer, which has been conventionally used as a terminal device for various data processing, and arranged this dot printer and a Braille engraving device consisting of a solenoid to face each other. On the other hand, when a predetermined key is energized, the key operation generates a certain electric signal, and the electric circuit is configured so that the Braille engraving device and the dot printer are energized by this electric signal. Then, a dot-type printer draws type on the front surface of the paper, and a Braille engraving device embosses Braille characters corresponding to the type on the back side of the paper. and the blind man,
Realizing that it was possible to obtain a printing and braille display device suitable for all sighted people, he filed a patent application for his invention ``Simultaneous Printing Device'' as Japanese Patent Application No. 104944 on August 20, 1976.

However, in the device according to the above application, as previously disclosed, the Braille engraving device and the character printing device are configured to face each other, and therefore, when trying to downsize the entire device, it takes up a lot of space that can be reduced. There are limits.

Therefore, as a result of further research and efforts, the present inventor focused on the recently developed ink-impregnated body made of sintered metal or ink-impregnated body made of porous resin, and developed a character printing device and a braille engraving device. The ink-impregnated body and the receiving part of the Braille engraving device are arranged in a vertical relationship, and on the other hand, the ink-impregnated body and the receiving part of the Braille engraving device are arranged with a predetermined distance between these devices, and the recording medium is inserted into the space, thereby forming the character printing device and the Braille engraving device. It has been found that by energizing the typewriter, it is possible to obtain a typewriter for characters and Braille that can print both characters and Braille characters from the back side to the front side of a recording medium, and the above-mentioned disadvantages can be solved at once. Moreover, in this case, since the ink-impregnated body is located at the upper part of the receiver, the ink-impregnated body itself can be easily replaced even if it wears out, and the Braille engraving head and its receiver remain in the same position. It has been found that clear and accurate Braille markings can be made because of the ability to

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a type for character Braille that allows blind people to clearly and quickly confirm the printed Braille characters, promotes downsizing of the typewriter as a whole, and allows for easy replacement of inking means. Provides a writer's head.

In order to achieve the above object, the present invention provides a typewriter for character Braille that displays Braille and characters on the same recording medium, and a character printing head that has a character printing means for printing characters on one side. and a Braille inscription head part which is located below the same side of the head part and has a Braille inscription means for embossing Braille characters, and which are arranged one character apart from each other; A character printing receiving part having a character printing receiving means and a Braille marking receiving part having a Braille marking receiving means located below the same side of the receiving part are arranged so that the two head parts face each other. and a receiving part arranged in a staggered manner, and by alternately energizing the character printing means and the Braille engraving means of the head part, the Braille and the characters are alternately printed one character at a time on the recording medium. It is characterized by the inscription above.

Next, a preferred embodiment of the head of the character/Braille typewriter according to the present invention will be described in detail with reference to the accompanying drawings.

In FIGS. 1 to 3, reference numeral 10 is
A head portion 10 for displaying characters and Braille is shown, and this head portion 10 is supported by a horizontal shaft 12 extending in the horizontal direction and held on a side wall (not shown). In the present invention, the head section 10 is divided into a character printing head section 14 and a braille engraving head section 16, and the character printing head section 14 is located above the braille engraving head section 16. That is, in this case, the head section 10 is supported by a support 18 that is horizontally movable about the horizontal axis 12, and the Braille inscription head section 16 is fixed to this support 18. As can be understood from FIG. 1, the Braille engraving head 16 has an upper surface.
It includes a housing 20 inclined at 90-Θ degrees (see FIG. 2),
Inside this housing 20, three solenoids and three rods whose rear ends are struck by these solenoids are arranged (not shown). Note that the rod can protrude from three holes 22, 24, and 26 that are vertically bored in the front part of the housing 20.

Next, the character braille head section 14 will be explained. The character printing head section 14 is attached to the upper surface of the housing 20, and is connected to the solenoid 28.
It basically consists of a plurality of wires (not shown), and a guide section 30 that guides the protrusion of these wires. Therefore, it will be understood that since the upper surface of the housing 20 is inclined by 90-Θ degrees as described above, the guide portion 30 is also inclined by Θ degrees (see FIG. 2).

A receiving portion 32, which is connected by a wire or the like and configured to move integrally, faces the head portion 10 configured as described above.

The receiving section 32 includes a character printing receiving section 34 corresponding to the character printing head section 14 and a braille engraving head section 1.
It basically consists of a character engraving receiving part 36 corresponding to 6. Therefore, the head portions 14, 16
A character printing receiving part 34 is arranged above the character engraving receiving part 36 in correspondence with this. in this case,
The lower part of the support body 38 constituting the receiving part 32 is bulged out and extended perpendicularly from the bulged part 40 to form a rectangular parallelepiped 42, and one side of the rectangular parallelepiped 42 corresponds to the holes 22, 24, and 26. hemispherical groove 4
4, 46, 48 are engraved. Further, a character printing receiving portion 34 is fixed to the upper surface of the rectangular parallelepiped 42 . The character printing receiving part 34 includes a cylindrical ink-impregnated body 54 rotatably mounted inside the deformed housing 50 by a shaft 52, and a rotating body 58 that is in pressure contact with the impregnated body 54 and rotated by a shaft 56. It consists of One circumferential surface of the ink-impregnated body 54 is connected to the housing 50
It is exposed to the outside through a window 60 formed on the front side of the. Note that a recess 62 is formed by extending the upper part of the support body 38 toward the rear side, and this recess 62 is used as a support for the shaft 64.

In the figure, reference numeral 66 is a roller disposed above the recess 62 and in contact with the shaft 64 to ensure smooth movement of the support 38 in the horizontal direction. is a shaft for penetrating a hole formed in the bulging part 40 to hold and move the receiving part 32.

The present invention is basically constructed as described above, and its operation and effects will be explained next.

As shown in FIG. 4, first, the recording paper 70 is automatically inserted between the head section 10 and the receiving section 32 from below. Then, perform the necessary key operations to connect the character printing head section 14 and the braille engraving head section 1.
When a predetermined electrical signal is sent to the head 6, both the heads 14 and 16 are energized by the signal. That is, rods (not shown) protrude from the holes 22, 24, 26 in response to the signals and are directed to the grooves 44, 46, 48 via the recording paper 70.
As a result, three points of Braille out of the six points are drawn on the recording paper 70. Next, support 1
8 is moved by half a point by a stepping motor (not shown), the remaining three points are inscribed in Braille, and the Braille is completed, and the support 18 is moved again for the next Braille engraving operation. Become. On the other hand, in the present invention, the character printing head section 14 is not biased during the braille marking operation. That is, as described above, when the support body 18 moves for the next Braille engraving operation, the head portion 14 is biased. Therefore, since the support body 18 is biased while moving in the horizontal direction, from the guide part 30 inclined by Θ degree,
Wires (not shown) are fed out one after another, but after printing is completed, normal characters are clearly displayed due to the correspondence between the running speed of the support 18 and the feeding speed of the wires. This is to avoid simultaneous energization of the braille engraving head section 16 and the character printing head section 14, to prevent the use of a large amount of current at once, and to downsize the power supply device.

Note that when printing characters, the wire brings the recording paper 70 into pressure contact with the ink-impregnated body 54. Accordingly, the color contained in the ink-impregnated body 54 will be transferred to the surface of the paper 70 as a character representation by the selective energization of the wire.

Further, the support body 38 is connected to the support body 18 by a wire (not shown). Therefore, when the support 18 is moved on to the next Braille inscription operation, the support 38 will also move equally in the same direction. For this reason, the shaft 64
The rotating body 58 that is in pressure contact with the ink impregnated body 58 also rotates, and the ink impregnated body 54 also rotates together with this. That is, a surface different from the peripheral surface of the ink-impregnated body 54 used in the previous character printing operation is always exposed in the window 60, thereby ensuring a clear next printing operation. Note that when the ink-impregnated body 54 is worn out, the shafts 52 and 56 may be loosened, the housing 50 may be removed, and a new one may be replaced. In this case, it will be easily understood that the exchange operation is easily performed. At this time, since the Braille inscription head part 16 and the Braille inscription receiving part 36 remain fixed, for example, the holes 22, 24,
26 and the grooves 44, 46, 48 will not be misaligned and the next braille engraving operation will not be inaccurate.

According to the present invention, as described above, in a typewriter for character printing, the ink-impregnated body can be easily replaced, and there is no need for complicated work such as moving other parts and redoing them. Therefore, this type of device has the advantage of being easier to handle.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and various improvements and design changes may be made without departing from the spirit of the present invention. Of course.
