<p>A control unit starts a first operation when a first detection unit detects rotation of an operation member in a first direction by an angle not less than a first angle and changes a control value for the first operation when a second detection unit detects rotation of the operation member in the first direction by an angle not less than a third angle larger than the first angle. Furthermore, the control unit starts a second operation when the second detection unit detects rotation of the operation member in a second direction by an angle not less than a fourth angle and changes a control value for the second operation when the first detection unit detects rotation of the operation member in the second direction by an angle not less than a second angle larger than the fourth angle.</p> |
