Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a typewriter configured to display Braille and characters on the same recording medium, and more specifically, the present invention relates to a typewriter that has both a Braille embossing mechanism and a character printing mechanism. The present invention relates to a typewriter for Braille characters that is configured to display Braille characters and characters on the same recording medium by operating a key commonly used for both.

Conventionally, various types of Braille devices for the blind have been proposed. However, it is extremely difficult for sighted people, especially those who are not familiar with reading Braille, to understand the meaning of the Braille characters displayed by these Braille devices for the blind. On the other hand, it is impossible for a blind person to read the characters printed on a regular typewriter.

Therefore, in order to facilitate written communication between blind and sighted people, it is most preferable to display Braille and characters in correspondence on the same recording medium. However, conventional devices developed for this purpose are large in size and difficult to handle, and it is difficult to imagine that they can be manufactured at low cost. Therefore, such conventional devices have not yet been widely used and remain inconvenient for blind people.

Therefore, an object of the present invention is to incorporate a Braille embossing device and a character printing device into the same typewriter, and to selectively activate one of the many keys arranged on the keyboard. A signal is generated electrically, and this signal causes predetermined Braille characters and corresponding characters to be displayed on the recording medium in a corresponding manner, so that both blind and sighted people can read the same information from the recording medium. To provide a typewriter for Braille characters, which is configured to be able to acquire information on the characters, to be small in size, and to be manufactured at low cost.

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

In FIG. 1, reference numeral 10 indicates a typewriter for Braille characters, and the front exterior of the typewriter 10 for Braille characters includes a keyboard 12 with a large number of keys arranged thereon, and a recording medium, for example, a paper-sized typewriter. A paper switching lever 14 for selecting a paper, a clamp lever 16 for clamping the paper, a count indicator 18 for displaying the number of copies, and a paper insertion slot 22 that can be opened and closed with a see-through plate 20 are provided. . On the other hand, on the rear exterior of the Braille character typewriter 10, there is a power switch 24 for supplying the necessary power, and a mode changeover switch 26 for selecting the mode of information on a recording medium such as text, braille, braille, and text. and hook member 27 for holding several types of roll paper as needed.
Hook hole 2 for attaching paper to set it through
8a and 28b are provided (see FIG. 2).
In FIG. 2, reference numeral 30 indicates a paper feed knob for feeding the recording medium.

The internal structure of the Braille character typewriter 10 having the external configuration as described above will be described next.

The casing 32, which provides the external appearance of the Braille typewriter 10, includes a bottom plate 34. Bottom plate 34
As shown in Figure 3, it is made of a rectangular metal plate with a rectangular cutout in the center so that when a long piece of paper is inserted, the excess length is drawn out. A first paper outlet 36 is formed to allow the paper to flow. At the rear corners of the bottom plate 34, vertically rising corner members 38 and 40 are arranged. The power switch 24 is fitted and fixed into the rectangular notch provided in the section 40. Note that the rubber ring 4 is inserted into the hole 42 provided in the corner member 40.
4, and a power line 46 for electrically connecting a power source (not shown) to the power switch 24 is inserted therethrough.

Next, a chassis plate 48 is placed and fixed in a hollow shape on the bottom plate 34. The chassis plate 48 is a substantially rectangular plate body, as is clear from FIG.
A rectangular second paper outlet 50 corresponding to the paper outlet 36 is formed at the front thereof. A power supply unit 52 incorporating a transformer (not shown) is attached to the rear of the chassis plate 48, and a pair of guide members 54a, 54b are erected between the power supply unit 52 and the second paper outlet 50. Ru. That is, these guide members 54a and 54b are for vertically fixing a printed circuit board 55 incorporating an electric circuit, which will be described later. Chassis board 4
A circular hole 56 is bored in one corner of the hole 8.
A stepping motor 58 for horizontally moving the Braille embossing mechanism and character printing mechanism is fitted into the hole 56. Four support rods 60 are planted adjacent to the hole 56, and these rods 6
The stepping motor 58 is fixed by inserting bolts into the holes of the plate 62 constituting the stepping motor 58 through the bolts 0 and 60, and attaching the motor mounting plate 64 from above. Therefore, the vertical drive shaft 66 of the stepping motor 58 is connected to the motor mounting plate 6.
4, and a rotational driving ring, that is, a pulley 70, is fitted into the tip thereof.

A pair of side plates 72a and 72b are provided upright on the chassis plate 48 constructed as described above. Left side plate 72a
As is clear from FIG. 5, the right side plate 72b has a linear front part, but a rear part is made of a metal plate having a large number of stepped parts 74a, b. Relatively large diameter holes 76a, 76b and 78a, 78 are provided in the upper portions of the side plates 72a, 72b, respectively.
In addition, semi-elliptic notches 80a and 80b having substantially the same height as the holes 76a and 76b are formed in front of the holes 76a and 76b.
Further, a pair of holes 86a, 88a and 8 are arranged diagonally below the notches 80a and 80b.
6b, 88b are drilled, and further holes 88a, 8
Holes 90a, b are at approximately the same height as hole 7b.
8a and 78b, respectively. hole 90
Relatively small diameter holes 92a, 92b (not shown) located diagonally above a, 90b and close to the stepped portion 74.
Holes 94a and 94b having substantially the same diameter as the holes 92a and 92b are formed diagonally below the holes 86a and 86b, respectively.

Note that reference numerals 95a and 95b are holes through which rods for engaging the eccentric cam and the clamp lever 16 are inserted, as will be described later.

Next, holding fittings 96a, b, and 98 are fixed to the outer sides of side plates 72a and 72b configured as described above. That is, the holding fittings 96a,
96b and 98 are both U-shaped bent plates, of which the holding fittings 96a, 96
b are inclinedly arranged between the holes 86a, 88a and 86b, 88b, respectively, and the holding fitting 98 is arranged between the holes 88b and 90b. The holding fittings 96a and 96b have pulleys 1
00 and 100b are rotatably supported, while a pulley 102 is rotatably supported on the holding fitting 98. In this case, a metal fitting corresponding to the holding metal fitting 98 is not attached to the outside of the side plate 72a. That is, as described above, the stepping motor 58 is disposed on the outside of the side plate 72a. Therefore, if a pulley 70 is pivotally attached to the drive shaft 66 of the stepping motor 58 as shown in FIG. 4, the pulley 70 will face the pulley 102 via the side plates 72a and 72b. become. For this reason, the pulley 100a and the pulley 100b have holes 86a, b and 88a,
b, and hook the wire 104 thereon; on the other hand, the wire 106, which is inserted through the holes 88a, b and 90a, b, is also hooked on the pulley 70 and the pulley 102.
If wire 104 and wire 106 are connected to each other by a portion thereof (see FIG. 5), stepping motor 5
It will be appreciated that the energization of 8 causes all the pulleys to rotate synchronously.

Next, the holes 92a, 92b and 94a, 9
4b is used to bridge the rods 108 and 110, and the rod 111 is bridged through the holes 95a and 95b.

Now, the side plate 72 formed in this way
Rods 108, 110 bridging a and 72b
Next, a head 112 for displaying Braille and characters and a head holder 114 for receiving the movement of this head 112 are attached. Head 1
12, as shown in FIG. 6, can be broadly divided into a braille head section 116, a character head section 118, and a head mounting bracket section 120. The braille head section 116 has three pins 122a, 1
22b, 122c are arranged in the vertical direction, and these pins 122a, 122b, 122c are housed in a casing 124 under the elastic force of a spring 123, respectively. In addition, as can be easily understood from FIGS. 7 and 8, the head mounting plate 126
Inwardly from the end of the lever receiver 12
8. Arrange the solenoid 130 and pin guide 132 in this order, and further engage the operating rod 134 to the pin guide 132. One end of the operating rod 134 engages with a groove 136 formed in the lever receiver 128, while the other end of the operating rod 134 engages with the groove 136 formed in the lever receiver 128.
It is formed so as to come into contact with the rear end portion of 22. Therefore,
When the solenoid 130 is energized, the operating rod 134
is electromagnetically attracted and uses the one end as a fulcrum,
The other end hits the tail end of the pin 122, resists the elastic force of the coil spring 123, is exposed forward from the head tip 138, and comes into contact with the recording medium.

In this case, as can be understood from Fig. 7, the lever holder, solenoid, and pin guide are set in two stages vertically on the left side of the head mounting plate, and in one set on the right side of the head mounting plate. Only installed. Therefore, the other end of each operating rod 134 is connected to the pins 122a, 122b, 122, respectively.
It will come into contact with c.

By the way, the character head section 118 is arranged adjacent to and below the Braille head section 116 (see FIG. 6).

In particular, it should be noted that in the present invention, the plurality of wires 140 that make up the printer head are offset by one character from the tandem pins 122 that make up the braille head section 116. (See Figure 7). That is, the wire 140 is not placed directly under the pin 122. This is to avoid simultaneous printing of Braille and characters, and to significantly reduce the power consumption of the excitation circuit for driving both pins and wires when energizing them. Note that a plurality of solenoids 141 as constituent elements of the character head section are connected to the head mounting plate 12 at the rear of the wire 140.
Stick to 6.

As described above, the head mounting plate 1 to which the Braille head part 116 and the ink character head part 118 are fixed is shown.
26 is further fixed to the head mounting bracket 120 by a conventional fixing means such as a screw. The head mounting bracket 120 includes a bearing part 142 and a bearing part 14.
A semicircular recess 144 is formed in the upper part of 2.
When the rod 108 is positioned within this recess 144, the head 112 is supported by the rod 108 and the rod 146. In this case, by fastening one point of the head 112 to the wire 106, the head 112 can be connected to the rods 108 and 146 under the force of the stepping motor 58.
will be moved above. At this time, Rod 108
Bearing 148 and rod 1 in contact with a part of
Linear ball bearing 150 that fits into 46
This helps ensure smooth movement of the head 112. In this case, the wire 106 is preferably engaged with the head 112 in the following manner.
That is, the support portion 142 of the head mounting bracket 120
A recessed portion 152 is formed in a part of. On the other hand, a part of the wire 106 is cut out, and an elastic member, for example, a coil spring 154 is attached to one end formed thereby.
4 is locked to a bolt 158 fixed to a part of the recess. According to the above configuration, even if the limit switch (not shown) that controls the reciprocating movement of the head 112 provided on the side plate 72b breaks down, the coil spring 154 can sufficiently absorb this forward movement and prevent the mechanical movement of the head 112. The pressing force is relaxed, and damage to the printer head and the like is prevented. Further, an effect of avoiding overload operation of the stepping motor 58 can be obtained.

Next, the head receiving fitting 114 will be explained.

The head receiving metal fitting 114 is connected to the upper receiving metal fitting 160.
and a lower receiving metal fitting 162. A roller 164 is rotatably supported at the center of the upper receiving metal fitting. The roller 164 has an O-ring 165 fitted around it. The collar 166 is coaxially pivoted to the bottom of the roller 164, and a roller 170 having an O-ring 168 is closely supported on the bottom surface of the collar 166. A shaft 172 passes through the roller 164, collar 166, and roller 170 stacked in this manner, and these elements are rotatably supported. Note that these are firmly held by the lid member 174. At this time, it should be noted that the O-ring 168 is exposed to the outside through the opening. This O
The ring is in pressure contact with the shaft, as will be described later.

On the other hand, an ink roller 176 is rotatably supported below the front half of the upper receiving fitting 160 so as to be in contact with the O-ring 165. A portion of the ink roller 176 is exposed to the outside through an opening 177 provided on the front surface of the upper receiving metal fitting 160 (see FIG. 9). The ink roller 176 needs to have enough strength to withstand even if the wire 140 of the head section 112 comes into contact with the recording medium under impact. Therefore, the ink roller 176 is preferably made of sintered nylon or sintered metal. Note that a series of three recesses 178 extending vertically are formed in the front surface diagonally above the opening 177.
These recesses 178a, 178b and 178c are
Pins 122a and 122b that constitute the head 112
and 122c, and serve as receiving portions for the three pin members.

Next, the lower receiving fitting 162 will be explained. As is clear from FIG. 9, the lower receiving fitting 162 has a bulged front portion to form a relatively large hole extending in the horizontal direction, into which the linear ball bearing 180 is fitted. inserted.

In addition, in FIG. 6, reference numeral 182 is a leg portion extending to the back of the upper receiving metal fitting 160,
Further, reference numeral 184 is a roller pivotally attached to the leg portion 182.

The head receiving metal fitting 114 integrated as described above is then supported by two rods. That is, the rod 110 is inserted into the linear ball bearing 180, while
A rod 186 is inserted into a semicircular space formed by the leg portion 182 and the back of the upper receiving fitting 160. At this time, both ends of the rod 186 are
Notches 80a, 80b of side plates 72a and 72b
Moreover, the O-ring 168 and the roller 184 abut against the side of the rod 186. Therefore, as will be described later, since the rod 186 can move within the notch 80, the head receiving fitting 114 is able to move inside the rod 110.
It is understood that it is possible to swing freely using the fulcrum as the fulcrum. That is, this serves to press the paper presser roller against or separate it from the paper supply roller, as described below. In addition, the head receiving metal fitting 114
is attached to the wire 104 at any location. Therefore, like the head 112, when the stepping motor 58 is energized, the wire 104 is pulled, so the head receiving fitting 114
12, it will move horizontally. At this time, linear ball bearings 180 and rollers 184 facilitate this movement. In this case, the O-ring 168 is in sliding contact with the rod 186, so when the head receiving fitting 114 moves, the O-ring 168 and the roller 184 rotate, and the roller 164 also rotates accordingly. As the roller 164 rotates, the other ink roller 176 also rotates in the opposite direction due to friction. Therefore, as the roller 164 rotates, the surface of the ink roller 176 that is impregnated with ink is always
It is exposed to the outside as a new side.

Next, the paper supply means will be explained. Specifically, the paper feeding means includes a paper feeding roller 188, a paper pressing roller 190, and the paper feeding roller 1.
88 rotation driving means, that is, a stepping motor 192. As clearly shown in FIG. 5, the paper feeding stepping motor 192 is mounted on the side plate 72b, and its drive shaft
94 is fixed so as to pass through the hole 78b and extend inward of the side plate. Therefore, one end of the paper feed roller 188 is rotatably supported by the side plate 72a, and the other end is connected to the drive shaft 194.
It will be attached to. In this case, the first
As shown in FIG. 0, a protrusion 195 is provided perpendicularly to the drive shaft 194, and a tube member 196 made of silicone is used as a part of the paper feed roller 188. a recess 197 into which the protrusion fits into the end of the recess 196;
If the stepping motor 192 is started, the tube member 1
Since the roller 96 is twisted, the rotational driving force thereof is not directly transmitted to the paper feed roller 188, but acts as a buffer. The paper pressing roller 190 is the fifth
As shown in the figure and FIG.
It is held by support means 199 loosely fitted to 6b. That is, the eccentric cam 201 is fixed to one end of the rod 111 bridged between the holes 95a and 95b, and the clamp lever 16 is fixed further outside the eccentric cam. Support means 1 consisting of a plate
99 is formed with a large hole 203 into which the end of the paper pressing roller 190 loosely fits, and a notch 8 is formed in the front.
It has a notch 205 corresponding to 0a. The support means 199 is held by pins 207 set on the side plate 72a. Therefore, when the clamp lever 16 is tilted forward, the cam 201 comes into contact with the end of the support means 199, the support means moves forward, and the paper pressing roller 190 also moves forward. That is, when the clamp lever 16 is tilted forward, it reaches the release state, and the paper pressing roller 190 separates from the paper feeding roller 188, and at the same time, the circumferential surface of the roller 188 comes into contact with the head receiving metal fitting 114, so that the receiving metal fitting The whole body will also swing forward. Therefore, by utilizing the space defined between the receiving metal fitting 114 and the head 112 and the space defined between the paper pressing roller 190 and the paper feeding roller 188,
As shown in FIG. 6, if paper for Braille characters is supplied through the first paper outlet 36 and the second paper outlet 50 using the guide member 200, the paper is ready for printing operation. become.

Next, the internal structure of the typewriter according to the present invention will be explained with reference to FIG.

First, the keyboard 12 consisting of keys for each valve is
The keyboard 12, which constitutes input means, introduces a predetermined signal to the mode determination means 202. The mode determining means 202 determines whether the signal input from the keyboard 12 is in a mode in which Braille and characters issued from all normal input keys are displayed at the same time, in a mode in which only Braille is displayed, or in a mode in which signals input from the keyboard 12 are already stored. Based on the information displayed, it is determined whether the copy mode is to output a predetermined number of copies of characters and Braille or only Braille. The mode determination means 202 is connected to a large-capacity character code storage means and a large-capacity Braille code storage means, which will be described later, and is connected to an ASC code conversion means 204, and the output side of the ASC code conversion means 204 is connected to a character code output means. 206 and Braille code output means 208.
Therefore, the signal determined by the mode determining means 202 is converted by the ASC code converting means 204.
After being converted into an ASC code, it is sent to the character code output means 206 in the case of a character input code, or to the Braille code output means 208 in the case of a Braille input code.
It will be introduced in Note that the output side of the ASC code conversion means 204 also includes a corresponding character presence/absence determination means 210 that determines whether or not a character corresponding to the input signal exists, and a corresponding character presence/absence determination means 210 that determines whether or not a character corresponding to the input signal exists, and a corresponding character presence/absence determination means 210 that determines whether or not a character corresponding to the input signal exists. It is connected to Braille grammar conversion means 212 for conversion. Therefore, in the case of a Braille input code, the signal is sent to the corresponding character presence/absence determination means 210, while in the case of a character input code,
The signal will be introduced into the Braille grammar conversion means 212.

The corresponding character presence/absence determination means 210 is connected to the character code output means 206, and the corresponding character presence/absence determination means 210 and the character code output means 2
06 has the function of reading out a large amount of stored data from the character data storage means 214 based on the input signal.

Next, one output side of the character code output means 206 branches to a large capacity character code storage means 206.
16 and the small capacity character code storage means 218 to store the read data signal in the large capacity character code storage means 216, while the small capacity character code output means 218 sequentially outputs the character code output means 2.
The data read by 06 is output.
The other output side of the character code output means 206 is connected to the movement amount control means 220, and its output signal is used as a control signal for the next stage. The output sides of the large-capacity character code storage means 216 and the small-capacity character code storage means 218 are connected to the character output control means 2, respectively.
22, the character output control means 222 is connected to
The character output means 22 is connected to the character output means 224 and controlled by the control signal of the character output control means 222.
Control 4. By the way, Braille code output means 2
08 is connected to the Braille data storage means 226, and one output side is branched and connected to the large capacity Braille code storage means 228 and the small capacity Braille code storage means 230, and the other output side is connected to the Braille data storage means 226. , is connected to the movement amount control means 220.
Therefore, based on the input signal, the Braille code output means 208 reads a predetermined signal from the data stored in the Braille data storage means 226 and stores it in the large-capacity Braille code storage means 228. The capacitive character code output means 230 sequentially outputs the data read out by the braille code output means 208. The output sides of the large-capacity Braille code storage means 228 and the small-capacity Braille code storage means 230 are connected to the Braille output control means 232.
2 is further connected to the Braille output means 234 and controls the Braille output means 234 by a control signal from the Braille output control means 232.

As will be described later, the movement amount control means 220 is for controlling the horizontal movement of the head 112 of this typewriter and the so-called paper feed in which the recording medium, that is, paper is fed out one line at a time. , the control signal is the stepping motor 58
and will be fed to the stepping motor 192. Note that the circuit is configured such that signals from various detection means 236 such as a micro switch for detecting the position of the head 112 are introduced into the movement amount control means 220, and the movement amount control means 220 is configured such that signals from various detection means 236 such as a micro switch for detecting the position of the head 112 are introduced.
Output mode selection means 238 is arranged so that each output mode of Braille only or copy can be selected,
The selection signal from the selection means 238 is configured to be introduced into the movement amount control means 220, and the signal is further configured to be introduced into the character output control means 222 and the Braille output control means 232.

Therefore, the actual use of the typewriter for Braille characters configured as described above will be explained.

First, by tilting the clamp lever 16 forward, the space between the head 112 and the head holder 114 as well as the paper feed roller 18 is removed as described above.
A predetermined space is created between the roller 8 and the paper pressing roller 190. Next, if the recording medium is a continuous book type,
Insert the paper upward from the back of the typewriter. If the recording medium is a single book type, paper insertion slot 2
2 to insert the medium downward.

Next, when the typewriter 10 for Braille characters is turned on, this typewriter waits for inputting information, and the operator selects the normal mode, Braille mode, or copy mode for output using the mode changeover switch 26. You can choose which. By selecting this mode, as shown in the circuit diagram above,
The output is the character output means 222, that is, the character head section 118 and/or the Braille output means 234.
In other words, the braille head section 116 is biased. That is, in the normal mode, the solenoid 130 of the braille head section 116 is energized based on the input signal, and the pins 122a to 122c are activated.
Any or all of them selectively protrude forward and are received in recess 178. Therefore, the recording medium between them is thereby divided into one vertical column, that is, three
Braille characters were printed on only one row of dots. Next, the stepping motor 58 is energized by the remaining one row, the head 112 is moved horizontally, and the pins 122a to 122c are energized again by one row. In the end, the braille is formed into two parts via the movement amount control means 220, so that the shape can be made smaller. Furthermore, since the power consumption is not consumed all at once for six Braille characters, the power supply unit can be made smaller. At this time, it must be noted that the character head 118 has already completed its printing operation before the corresponding Braille characters are completed. That is, when half a character of Braille has been etched, the head 112 moves horizontally by half a character under the control of the movement control means 220 for the next Braille operation. During the moving operation, the character head section 118 is controlled by the control means 220.
The wire 140 is energized and protrudes outward from the head tip 138 in response to the input signal. Since the ink roller 176 exists there through the recording medium, the ink contained therein is transferred to the recording medium in response to the protrusion of the wire 140, thereby backing the characters. However, since the pins 122 and the wires 140 are arranged one character apart from each other, when the recording medium is taken out, they will be unevenly aligned in position. After the last character is pressed, if the space key is pressed, the Braille corresponding to that character will be printed.

Of course, when the Braille mode is selected, only Braille is output among the above operations.

Next, a case where copy mode is selected will be explained.

Once the copy mode is selected, the number of copies is then input using the numeric keys on the keyboard 12. When you press the start button, the data will be output for the set number of sheets. In this case, the copy mode is selected by switching the mode changeover switch 26, the mode determining means 202 determines that it is the copy mode, and the signal is already stored in the large capacity character code storage means 216. The character output control means 222
On the other hand, the signal reads data already stored in the large-capacity Braille code storage means 228 and outputs the data to the Braille output means 234 via the Braille output control means 232.
will be energized. In this case, as will be described later, whether or not both or one of the character output means 224 and the braille output means 234 are energized depends on the selection of the output mode.

When the head 112 moves to the set margin, the stepping motor 192 is driven by the biasing of the detection means 236, the paper feed roller 188 is rotated, and the recording medium is moved upward by one line.

According to the typewriter of the present invention, as described above, not only can characters and/or Braille be selectively output, but the typewriter can also be made smaller and consume less energy. It is manufactured economically and inexpensively, and its continued use is not particularly expensive. Moreover, since a storage means is provided to store input data, it is possible to provide necessary information in Braille on a plurality of pages. Furthermore, since the Braille head and the text head are arranged in a vertical relationship, the Braille text is always brought out before the text. Therefore,
The function of the Braille itself will not be impaired due to the bulging part of the Braille that emerges from the narrow space between the head and the receiving member being crushed, and the characters will not be rubbed and become difficult to read.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that various improvements and design changes can be made without departing from the gist of the present invention. It is.
