<p>Provided are a driving system including a tooth clutch, and a register employing the driving system. The driving system includes a driving axis; a first tooth gear fixed on the driving axis and rotating according to rotation of the driving axis; a second tooth gear that is meshed with or separated from the first tooth gear and that is coupled to the driving axis so that the second tooth gear and the driving axis form a gap therebewteen; a passive axis coupled to the second tooth gear, coupled to the driving axis so that the passive axis and the driving axis form a gap therebetween, and dependently moved according to whether the first tooth gear and the second tooth gear are meshed or separated; and a first gear installed on the passive axis. Accordingly, a plurality of blocks can be equally used, and thus the lifetimes the block can be similar to one another. In addition, since the necessary number of blocks selected from all the blocks can be used, power consumption can be reduced.</p> |
