<p>PURPOSE:To eliminate an increase in tape tension in pinch roller pressing operation and to eliminate the elongation and damage of a tape, the breakage of a head, etc., by moving a guide post associatively with the pinch roller pressing operation. CONSTITUTION:When a cassette 1 is loaded and a cassette detection switch detects the cassette 1, a base 29 where posts 5 and 6 are implanted, a base 31 where posts 8 and 9 are implanted, and a base 32 where a post 10 and a pinch roller 11 are implanted begin to move along groove parts 30a, 30b, and 30c respectively and a tension regulator post 7 begins to rotate around a shaft 33 to draw the tape 4 out of the cassette 1. The base 29 is positioned by a catching member 13 and a base member 14 and the base 32 is positioned by a catching member 15; and the post 7 stops at a specific position and thus the loading is completed. Thus, the tape 4 is wound helically around a drum 28 and opened to the right and left by the posts 7 and 10 to abut on a fixed head and other posts, thereby forming a tape path.</p> |
