Claims

[Claims for Utility Model Registration] It is erected on the base 21, and has a male threaded portion 22a formed in the upper part of the cylindrical surface, and a female threaded hole 22b with a smaller pitch than the male threaded portion 22a formed in the upper end surface. a shaft 22 whose lower end abuts the base 21 and a preload spring 23 fitted into the shaft 21; an outer cylindrical surface abuts the tape 25 to restrict vertical movement of the running tape 25; , a flanged guide roller 24 having large diameter portions 24b, 24c at the upper and lower portions of the inner cylinder surface, and a small diameter portion 24d formed in a step shape approximately in the center; A first bearing 26 whose lower surface is pressed by the preload spring 23, whose upper surface is in contact with the lower stepped wall surface of the small diameter portion 24d of the guide roller 24, and which rotatably supports the guide roller 24; and an inner ring. a second bearing 27 through which the shaft 22 is inserted, the lower surface of the inner ring abuts the upper stepped wall surface of the small diameter portion of the guide roller 24, and rotatably supports the guide roller 24; Screwed into part 22a,
The lower surface presses the inner ring of the second bearing 27, and has a nut 28 for regulating upward movement of the guide roller 24, and a male threaded portion 29a that is screwed into the female threaded hole 22b of the shaft 22, A tape guide roller position adjustment device comprising: a cap 29 that presses the upper surface of the nut 28;
