Abstract

A thermal transfer ribbon is prevented from sticking to a brake post in a high humid environment when passing between the brake post and a brake pad. A thermal transfer ribbon 1, which includes a substrate and a transfer layer on the substrate, passes clockwise around a brake post 2, which is supported on a base 3. The brake post 2 includes a lower circular stationary portion 4 having a lower flange 5 therebeneath and integral therewith. A post 6, which extends from the base 3 through openings in the circular portion 4 and the flange 5, has a pair of rollers 7 and 8 rotatably supported thereon. The upper end of the post 6 is of smaller diameter than the remainder of the post 6 to support an upper circular stationary portion 9 having an upper flange 10 thereabove and integral therewith.

Multi-Roller Brake Post

A thermal transfer ribbon is prevented from sticking to a brake post in a high humid environment when passing between the brake post and a brake pad. A thermal transfer ribbon 1, which includes a substrate and a transfer layer on the substrate, passes clockwise around a brake post 2, which is supported on a base
3. The brake post 2 includes a lower circular stationary portion 4 having a lower flange 5 therebeneath and integral therewith. A post 6, which extends from the base 3 through openings in the circular portion 4 and the flange 5, has a pair of rollers 7 and 8 rotatably supported thereon. The upper end of the post 6 is of smaller diameter than the remainder of the post 6 to support an upper circular stationary portion 9 having an upper flange 10 thereabove and integral therewith. Each of the rollers 7 and 8 and each of the circular portions 4 and 9 have the same diameter. Circular portions 4 and 9 have the same height, which is less than the height of the rollers 7 and 8. A brake pad 11, which is supported in structure (not shown), continuously urges the ribbon 1 against the brake post 2 with the transfer layer of the ribbon 1 riding around the brake post 2 while the brake pad 11 bears against the substrate of the ribbon 1. The distance from the bottom of the upper flange 10 to the top of the lower flange 5 is greater than the width of the ribbon 1 so that the upper edge of the ribbon 1 rides along the circular portion 9 and the lowe...
