Claims

[Claims for Utility Model Registration] 1. A tape guide cylinder formed by rolling a rectangular plate-like body into a cylindrical shape, and having engaging notches formed at both ends of the facing edges of the rectangular plate-like body, and this tape guide. The tube is fitted onto the outside, and a guide tube mounting shaft is formed with an engagement protrusion that engages with the notch at a position corresponding to the engagement notch, and the tape is guided by the engagement notch and the engagement protrusion. In a tape guide device designed to prevent the tube from rotating on the mounting shaft, the engagement protrusion is formed protruding along the axial direction near the base of the mounting shaft, and the tape guide tube is shaped like a rectangular parallelepiped. The engaging notch is formed of a rectangular notch having the same width as the engaging protrusion and an expanding notch formed in the open end of the notch so as to gradually expand in the opening direction. A tape guide device featuring: 2- The tape guide device according to claim 1, wherein the expanding cutout is formed into an isosceles trapezoid shape by diagonally cutting both edges of the open end of the rectangular cutout. 3' Expansion notch is made into a right-angled trapezoid by diagonally cutting one edge of the open end of the rectangular notch and leaving the other edge as it is so that it continues to the edge of the rectangular notch. A tape guide device according to claim 1 of the patent registration claim.
