Abstract
PURPOSE:To surely detect the abnormality of a driving device by executing a driving control so that a head moves between stoppers at safety speed, and comparing the actual moving distance of the head with a distance between the stoppers. CONSTITUTION:A driving device 12 is controlled so that a head 7 moves to one of stoppers 9L, 9R at safety speed, the speed of the head 7 is detected by position information of a head position detecting means 10, the position of the head 7 is read, when the speed of the head 7 has become '0', and the driving device 12 is controlled so that the head 7 moves to the other of the stoppers 9L, 9R at the safety speed. Also, when the speed of the head has become '0', the position of the head 7 is read, and by comparing the moving distance between these two positions with the distance between the stoppers 9L, 9R, whether the driving device 12 is normal or not is discriminated. That is, in order that the head 7 can move at the prescribed safety speed, even when there is an obstacle in a carrying path of the head 7, the damage of the head 7 and the driving device 12 can be prevented, and also, since the distance between the stoppers 9L, 9R is used as a reference, the abnormality of the driving device 12 can be detected surely.
