a first frame and a second frame which are arranged at a predetermined interval in an axial direction of the plurality of number wheels (3 - 12) and partition the space around the plurality of driven gears (3a - 12a) into a first space that stores the plurality of driven gears and a second space outside the first space; a third frame arranged between the first frame and the second frame; a plurality of first driving shafts each including one end rotatably supported by the first frame, and the other end rotatably supported by the third frame; a plurality of first driving gears which are fixed to the plurality of first driving shafts, respectively, and mesh with a plurality of first driven gears (4a - 6a) included in the driven gears (3a - 12a), respectively; characterized by further comprising a plurality of first motors which are connected to the one end sides of the plurality of first driving shafts, respectively, and arranged in the second space, and drive the plurality of first driving shafts, respectively; a plurality of second driving shafts located on the same axes as the plurality of first driving shafts, respectively, each of the plurality of second driving shafts including one end rotatably supported by the third frame, and the other end rotatably supported by the second frame; a plurality of second driving gears which are fixed to the plurality of second driving shafts, respectively, and mesh with a plurality of second driven gears (10a - 12a) included in the driven gears (3a - 12a), respectively; a plurality of intermediate shafts which are arranged on an outer side than the plurality of second driving shafts in a radial direction of the plurality of number wheels (3 - 12) and extend in parallel to the plurality of second driving shafts, and are connected to the plurality of second driving shafts by gear coupling, respectively, each of the plurality of intermediate shafts including one end rotatably supported by the first frame, and the other end rotatably supported by the second frame; and a plurality of second motors which are connected to the one end sides of the plurality of intermediate shafts, respectively, and arranged in the second space, and drive the plurality of intermediate shafts, respectively. a plurality of number wheels (3 - 12) which are individually rotatable and are arranged on the same axis;
