  • the space between the teeth of the racks 611 and 514 is small, compared with the situation of switching from the second-shaft driving form to the first-shaft driving form, the situation that the racks 611 and 514 are not engaged with each other is difficult to generate. Therefore, as long as the precision of engagement of the racks 611 and 514 is high, for the second-shaft switching treatment, the treatment from the step S204 to the step S206 used for enabling the driving motor 100 to pre-rotate may also be omitted.
