<P>PROBLEM TO BE SOLVED: To change operability of an operation ring to appropriate operability in accordance with an operation item. <P>SOLUTION: A drive control device includes: a fixed member; an operation ring disposed so as to be manually rotatable relative to the fixed member; a vibrator which is disposed on one of the fixed member and the operation ring and is disposed so as to come into contact with an opposite surface of the other of the fixed member and the operation ring; position detection means which detects the position of the operation ring relative to the fixed member; and operation force amount control means which controls drive of the vibrator to change a contact friction force at the time of contact with the fixed member or the operation ring. When the operation ring is manually rotated relative to the fixed member, the operation force amount control means controls the vibrator so that the contact friction force applied to the operation ring gives a click feeling. <P>COPYRIGHT: (C)2013,JPO&INPIT |
