PURPOSE:To reduce the processes of screw driving and screw loosening to improve the efficiency considerably by positioning a taper pin to position a video head. CONSTITUTION:When a video head 5 is set on a rotating jig 7 and a taper pin 9 is allowed to fall, the video head 5 is moved in the direction of an arrow B by a hole of the video head 5 and the force of a taper part in the direction of an arrow (x) of the taper pin 9 and is stopped at the end face of a pats regulating plate 8. Simultaneously, the video head 5 is pressed in the direction of an arrow A by the force of the taper part in the direction of an arrow (y) of the taper pin 9 and is fixed. A parts retaining pin 10 is slid together with the taper pin 9, and its point contact on the taper part due to the taper pin 9 is regulated, and thereafter, its face contact due the pats retaining pin is regulated. In case of release of regulation, the taper pin 9 releases first the regulation of the video head 5 by a difference of force between springs 12 and 13, and the pats retaining pin 10 releases it next. |
