Abstract
A frequency control apparatus includes: an input operation unit which detects a presence/absence of an input of a predetermined operation by an operator; and a control unit which, when the input of the predetermined operation by the input operation unit is detected, calculates radio frequencies, each of the radio frequencies being where a minimum value of differences with respect to multiplied frequencies of a current drive frequency of a device is less than or equal to a predetermined value, and which changes the current drive frequency of the device so that minimum values of differences between the calculated radio frequencies and multiplied frequencies of the changed drive frequency are greater than or equal to a predetermined value. The control unit changes the drive frequency to lessen a change width before and after the change by either increasing the drive frequency or decreasing the drive frequency.
