PURPOSE:To make it possible to adjust properly the print interval for printing simultaneous with dotting, by rotating the Geneva following wheel fitted to the dotting frame by a Geneva driving wheel to calculate positions of the dotting material and the printing material through the transmission device. CONSTITUTION:Pin 106 of eneva driving wheel 103 is linked with one groove of Geneva following wheel 113 after completion of the dotting operation corresponding to the input value; and when wheel 113 is rotated at 60 deg., this rotation rotates gear set 116 at 30 deg. intermittently through the bevel gear of tooth ratio 1:2. Consequently, ink pal wheel 133 is rotated at 30 deg. while interlocked with bevel gears 103a and 103b of tooth ratio 1:1, vertical shaft 131, and collar 132 to cause the ink tank of a prescried color for corresponding type part 128 of printing material 110 to be opposite to ink pad wheel 133. As a result, the print interval can be adjusted properly.
