Description

Изобретение относитс к средствам воспроизведени тактильной информации в коде Брайл и может быть использовано в средствах преобразовани информации дл воспри ти ее слепыми, прежде всего в качестве тактильного диспле ЭВМ.The invention relates to means of reproducing tactile information in the Braille code and can be used in means of converting information to perceive it blind, primarily as a tactile display of a computer.

Цель изобретени - расширение возможностей при воспроизведении информации в коде Брайл .The purpose of the invention is to enhance the ability to reproduce information in Braille code.

На фиг. 1-2 изображено устройство дл воспроизведени тактильной информации, ортогональные проекции.FIG. 1-2 depicts a device for reproducing tactile information, orthogonal projections.

Устройство дл воспроизведени тактильной информации состоит из носител информации, включающего установленные на общей оси 1 одну или несколько пар 2 восьмигранных дисков 3 и 4 (на фиг. 1 условно изображены две пары). На каждую из граней 5 каждого из дисков 3 и 4 нанесены символы трехточечного полукода Брайл в виде выступов 6, образующие одну из возможных рельефных комбинаций, включа пустую грань 7. По взаимному расположению комбинаций выступов все диски одинаковы.A device for reproducing tactile information consists of a storage medium, including one or several pairs of 2 octahedral disks 3 and 4 mounted on a common axis 1 (two pairs are conventionally shown in Fig. 1). On each of the faces 5 of each of the disks 3 and 4, three-point Braille semi-code symbols are applied in the form of protrusions 6, forming one of the possible embossed combinations, including the empty edge 7. According to the mutual arrangement of the combinations of projections, all the disks are identical.

Наружные торцы дисков 3 и 4 каждой пары 2 снабжены зубчатыми насечками, образующими ведомые шестерни 8 и 9 Носитель информации соединен с механизмом шагового перемещени , состоит из промежуточных шестерен 10 и 11, установленных на ос х 12 и 13, и ведущих шестерен 14 и 15, установленных на ос х 16 и 17 шаговых двигателей 18 и 19.The outer ends of the disks 3 and 4 of each pair 2 are provided with gear notches, which form the driven gears 8 and 9. The information carrier is connected to the stepping mechanism, consists of intermediate gears 10 and 11, mounted on axes 12 and 13, and leading gears 14 and 15, installed on axles 16 and 17 stepper motors 18 and 19.

На пустой грани 7 каждого из дисков 3 и 4 заподлицо установлен посто нный магнит 20. Параллельно грани 7 с зазором, обеспечивающим свободное вращение дис ка 3, установлен геркон 21, подключенный к контроллеру управлени устройством . Двигатели 18 и 19 подключены к формирователю импульсов (формирователь импульсов и контроллер не показаны) Сверху устройство закрыто панелью 22 с окнами 23 дл считывани информации.A permanent magnet 20 is flush mounted on the empty face 7 of each of the discs 3 and 4. Parallel to the face 7 with a gap to allow the disc 3 to rotate freely, a reed switch 21 is mounted to the device control controller. The motors 18 and 19 are connected to a pulse shaper (the pulse shaper and the controller are not shown). The device is closed from above by a panel 22 with windows 23 for reading information.

Устройство работает следующим образом.The device works as follows.

Двигатели 18, 19 - двухполюсные шаговые двигатели известной конструкции. При подаче на них импульса посто нного напр жени ротор совершает поворот наThe motors 18, 19 are bipolar stepper motors of known design. When a DC pulse is applied to them, the rotor makes a turn by

Таким образом, за один такт двигател 18 и 19 (поворот на 180°) диски 3 и 4 поворачиваютс на 1/8 оборота , т. е. смещаютс на одну грань. Установка любой комбинации выступов обеспечиваетс не более чем за четыре такта. После включени питани управл ющего средства формирователь импульсов выдает на все двигатели 18 и 19 серию импульсов чередующейс пол рности, в результате чего происходит дискретное, шаговое180 °. The direction of rotation is determined by the polarity of the pulse. The ratio of the number of teeth on the driven gears x 8 and 9 and the leading gears x 14 and 15 is chosen to be 4: 1. Thus, in one stroke of the engine 18 and 19 (180 ° turn), the disks 3 and 4 are rotated 1/8 of a turn, i.e. they are shifted by one face. Installation of any combination of protrusions is provided in no more than four cycles. After turning on the power of the control means, the pulse former generates a series of alternating polarity pulses on all the motors 18 and 19, as a result of which a discrete, stepwise

In window 23 of panel 22, the required symbol is set. RAM 5 records information about the position of each of the disks 3 and 4 and about the polarity of the last rotating pulse, replacing the previous information. When the next character is played, the cycle is repeated.

Claims

1. A device for reproducing tactile information, consisting of the rotation of their rotors, which, through gear-ig l information connected to the mechanism

Neither 4–10–8 (15–11–9) is transferred to discs 3 and 4. Before each clock cycle, including the first one, the controller checks whether the switch is closed. If closed, the pulses to the corresponding motor are stopped. As a result, all disks 3 and 4 are installed in the same (initial) position. The information of the polarity of the last pulse supplied to the corresponding engines 18 and 19 is entered into the RAM of the control means. Information about the current position of each disk 3 and 4 is also entered into the RAM (after setting to the initial position, this information is the same for all disks).

The ROM of the control means contains information on the position of each of the disks 3 and 4 for any character of the Braille code. To play the character controller based on ROM information and RAM information
