ABSTRACT:
A device (1) for moving a book (2) with a clamping device (3) moved by a first drive (22, 23) and having two clamping jaws (3a, b) that can be displaced in a parallel to open and close the clamping device, with a gear mechanism (8) on the moving clamping device (3) that converts a rotative movement into a linear adjusting movement for the clamping jaw (3a, b) which can be displaced in parallel, with a controllable second drive (21) that is arranged stationarily, and with a permanent driving connection (13, 14, 15) between the second drive (21) and the gear mechanism (8). The second drive (21) is not arranged on the moving system, such that the clamping device (3) can be realized in a lightweight construction. Pneumatic and electric connecting lines and signalling lines (35a, b) for the second drive (21) can be permanently installed.
