One side edge 16 of a lightweight, freely movable plate- shaped electronic screen 18 bears a manoeuvring device 10 connected to the side edge for guiding a cursor on the screen by action on one of the manoeuvring members of the manoeuvring device in the form of a rotatable ball 20 which can be acted on using the thumb 26 of the hand which holds the manoeuvring device by virtue of the fact that the manoeuvring member is arranged on that side of the manoeuvring device which faces in the same direction as the front side of the screen. The screen with the manoeuvring device can, as a separate unit, be moved to different positions in relation to the user, the thumb of the hand which holds the manoeuvring device having contact with the rotatable ball 20 in all positions of the screen. <IMAGE> |
