Abstract

PURPOSE:To make a petal-type type wheel available for braille types and to obtain a low-cost and low-noise printer having good workability for writers of a braille composition, by a method wherein the petal-type type wheel comprises a type portion consisting of a set of normal characters and dots for braille capable of printing braille letters corresponding to the respective normal characters by being combined. CONSTITUTION:A petal-type type wheel consists of a mount hole 2 to a printer body, a center disk 1 having square holes 3 regulating a rotating direction, a spoke portion 4 extending radially from the disk 1, and a type portion 5 provided at the tip end of the spoke portion 4. In this construction, with a standard dimension of the longitudinal arrangement of two dots, only the following 3 sorts of types are used: Type-I wherein two dots are spaced longitudinally 1.1mm from a type center line 6 respectively, Type-II wherein only one dot is spaced 1.1mm from the type center linen outwards, and Type-III wherein only one dot is spaced 1.1mm from the type center line inwards. All braille letters can be printed by use of the 3 sorts of types.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a petal-shaped Braille wheel that has type characters at the tips of radially projecting spokes and is used as a printer to print Braille text and regular text.

[Conventional technology]

Braille text is expressed by the character pattern in Table 2, which is a combination of the presence or absence of the six dots displayed in Table 1. Figure 10 shows 5 Braille characters having the above 6 dots 16.
FIG. 2 is a diagram illustrating a petal type type wheel arranged under the conditions shown in Table 1 and overlapping on a petal type type wheel consisting of type type 15 attached to the tips of spokes 14; According to Fig. 10, when three dots are arranged vertically, the Braille character corresponding to the normal character of 1 (km) has a vertical length that exceeds the normal character size limit and a width that exceeds the normal character size limit. also has a width equivalent to the width of two normal characters.

Table 1 Table 2 [Problems to be solved by the invention] As mentioned above, the Braille characters corresponding to each ordinary character are 1
Because each individual character occupies a large area, it is difficult to create a Braille printing device using a printer using a petal-type type wheel.As a result, the product price as a printer is expensive and the noise level is high. There was a problem in that it was quite inconvenient for the creator of Braille text.

The present invention makes it possible to produce Braille type using a petal type type wheel, and at the same time provides Braille text creators with an easy-to-operate, inexpensive, and low-noise printer that enables them to create texts with stable Braille quality. The purpose is to

[Means for solving problems]

The petal type type wheel of the present invention is characterized in that the type part consists of a set of regular characters and Braille dots that can be combined to print Braille characters corresponding to each regular character,
This braille dot is up to 12 dots vertically, or M
It consists of an array of up to three dots in one row.

Therefore, it is possible to print normal sentences and Braille sentences with one set of petal type type wheels, and to provide an inexpensive, low-noise printer with good operability, and to make it possible to create sentences with stable Braille quality.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a top view of an embodiment of the petal type type wheel of the present invention, FIG. 2 is an enlarged view of a type having two dots arranged in a vertical line, and FIGS. b) is a front view and a side view showing the dimensions of a type in which two dots are arranged in a vertical line, and FIG. 4 is a diagram showing the types of Braille type used in this embodiment.

Plink - A central disk 1 having a mounting hole 2 for attaching to the main body and a square hole 3 for regulating the direction of rotation, spoke portions 4 extending radially from the disk 1, and type portions 5 provided at the tips of the spoke portions 4. A petal type type wheel is constructed. Table 3 shows the typeface corresponding to each finger in FIG.

Table 3 According to Table 3, finger number is 28.30 and 8.
4 are provided with Braille type. Braille type is based on the dimensions of two dots arranged in a vertical line as shown in Figures 3 (a) and (b), and the size of two dots arranged vertically as shown in Figure 4. 1.1 each for center line 6
mmflfl! and type II, which is arranged with only one piece 1, 1 mdlk outside the center line of the type.
It is composed of only three types of m-type type letters arranged at a distance of 1.1 mm inside the type center line, and all the Braille characters shown in Table 2 can be printed using these three types of type letters.

Now, in order to print all characters in Braille using these three types of type, move the carriage equipped with the petal type type wheel and other printing mechanisms to the digit spacing #3 as shown in Table 1. F3
If printing is performed by moving the paper by tmra, the left and right columns can be printed, and the vertical direction can be printed by moving the paper feed system by 2.2 mm. To explain this using Figure 5,
The Braille characters corresponding to A and H only need to be printed with ■ and ENG, respectively, and C1D and E are II and II, II and I, and 1.
For 1 and ■, move the carriage 3.8 mm each, for K, print II first, then feed the paper 2.2 mm, then print ■, and for Z, first! It is sufficient to print (2), advance the paper 2.2 mm, then print m, and then print the cutting by moving the carriage 3.8 mm.

FIG. 6 is a top view of a petal type type wheel according to another embodiment of the present invention, and the reference numbers are the same as in FIG. In this example, the type is composed of up to three dots in one vertical column, the center line of the type passes through the center of the center dot, and the dots are arranged 2.2 cm apart on each side and bottom. ing. Figures 7(a) and 7(b) show front and side views of the dimensions of the three reference dots; in this case, the type of type compared to the first embodiment is as shown in Figure 8. Like i-Vi
i, but all Braille characters can be printed by simply moving the carriage by 3.8 mm, and there is no need to feed the paper. FIG. 9 shows examples of the characters used when printing A, B, C, D, and E and the movement of the carriage.

〔Effect of the invention〕

As explained above, in the present invention, in addition to a set of regular characters, up to 2 or up to 3 Braille dots are arranged in a vertical column on the type part formed at the tip of the spoke part of the petal type type wheel. By using this in conjunction with paper feeding or carriage movement, it is possible to create Braille text by simply adding several types of Braille type to the petal type type wheel normally used for text, making it easy to use and inexpensive. This has the effect of providing a noisy printer.
