<p><P>PROBLEM TO BE SOLVED: To make it possible to bypass or reduce the generation of the case that a movable object stops at a position where the movable object interferes with a game in the case operation abnormality is generated in the movable object. <P>SOLUTION: The generation of the case where a movable object 141 stops at a position where the movable object 141 interferes with a game is bypassed or reduced when operation abnormality is generated in the movable object 141 by a drive source moving the movable object 141 in a direction to a first position when a detecting means does not detect that the movable object 141 is present in a second position although a measuring means measures a driving quantity larger than a driving quantity of the drive source required for moving the movable object 141 from the first position to the second position or a driving time more then a driving time of the drive source required for moving the movable object 141 from the first position to the second position. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
