Claim 6:
7. The folding control method according to claim 6, wherein
in a case in which the difference between the number of first pulses and the number of second pulses is equal to or greater than the predetermined value a in the primary comparison step and the difference between the number of first pulses and the number of second pulses is less than the predetermined value b in the secondary comparison step, the step of the control module controlling at least one of the first motor and the second motor based on the difference between the number of first pulses and the number of second pulses comprises:
the control module reducing the duty ratio of a driving signal applied to a motor having a larger number of pulses, which is one of the first pulses and the second pulses;
the control module determining whether the difference between the number of first pulses and the number of second pulses for a predetermined time is equal to or greater than a predetermined value c (a tertiary comparison step); and
the control module restoring the reduced duty ratio of the driving signal to an original value upon determining that the difference between the number of first pulses and the number of second pulses for a predetermined time is less than the predetermined value c.
