The book support comprises two container parts (1,5) reciprocally pushable together, each with a horizontal support part (2,6) and a pair of outwardly projecting vertical side parts (3,4,7,8). At least the first side part (3) and the third side part (7) are provided with the first (9) and second components, which incline slightly towards the horizontal line. - With mutual horizontal displacement, the container parts are made to alter their reciprocal distance in a vertical direction. |
