<p>PURPOSE:To prevent the position change of a contact part between a tilted pole and a tape by designing each turning member so that the turning direction position of each turning member is adjusted on each base while the vicinity of a vertical line is used as a turning center and passing through a point on the center line of a tilted pole having the same height as the midpoint of the tape center line with which the tape is brought into contact. CONSTITUTION:A line RC passing through a point Y on a tilted pole center line PC having the same height to a reference face, i.e., a chassis 15 and the midpoint X of a tape center line TC at a part surrounded by points A-D contacted by a tape T to a tilt pole 6 and vertical to the chassis 15 and a support shaft 16 are made coincident. The line RC is used as the turning center, each turning member 14 is turned on a base 13 to change the tilt direction of the tilt pole 6 thereby adjusting the tilt angle of the tape T to a drum 3, then the position where the tilt pole 6 is brought into contact with the tape T is almost unchanged. Further, the loading member 12 at the tape winding side has the similar structure and the position where the tilt pole 7 is brought into contact with the tape T is almost unchanged. Thus, the relation between a guide roller 5 and the tilt pole 7 is entirely unchanged.</p> |
