| 摘要 |
The invention relates to a device for the punctiform representation of graphical information which may be read by touch, in particular for the representation of Braille script, comprising a support sheet, a number of systematically-arranged touch points and actuators for activating or deactivating selected touch points, whereby the touch points are formed such as to be integral with the support sheet. The touch points (2) have a touch region, which, in the activated state, extends above the plane formed by the touch surface of the support sheet and a flexible boundary region between the support sheet and the touch region and an erasing element is provided to bring all the touch points into the activated state, or into the deactivated state, by means of a return spring action on the touch region on or below the plane formed by the touch surface on the support sheet.
