摘要:PURPOSE: To facilitate the vertical alignment of the pivot pin for movable tape
guide element by installing a material collection section disposed asymmetrically about
the center of the pin leg. CONSTITUTION: A material collection section which is arranged
asymmetrically about the pin leg is provided so as to make a vertical alignment of a pin
which can be determined in advance against the internal face of the pin. For instance, a
narrow ring groove 17 is provided around the leg 16 of a pivot pin 14, and this ring
groove is surrounded by a supporting or rotating margin 18 for a standard roller having a
through supporting hole. Around this rotating margin 18, a somewhat low high place 19
is installed and this high place can possess a four-cornered traversing face or another
type of face. Thus, the pin can be pulled in a specified direction by strong material
contraction in the region surrounding the pin to make a specified vertical alignment of
the pin in advance.
