Abstract
A Braille cell having a pressure-exerting member in the form of a bar or leaf spring, of which one end can be displaced with the aid of a first displacement mechanism in a direction that is perpendicular to a longitudinal direction. One end of the pressure-exerting member is configured for placement in either a first or second position. In the first position, the pressure-exerting member does not place touch pins in a high position, while in the second position, the pressure-exerting member does place the touch pins in a high position. A second displacement mechanism is configured to displace the end of the pressure-exerting member, after the end has been disposed in one of the first or second positions, in the longitudinal direction, in such a manner that a touch pin is placed or is not placed in the high position. This allows a touch pin to be fixed in the correct position with respect to the touch surface of the touch board in a very simple manner.
