ABSTRACT:
A device for connecting a toothed timing belt to a printhead carriage includes an arcuate member and a pair of posts extending downwardly from the carriage. The arcuate member includes a generally concave surface and a generally convex surface which is complementary to the toothed configuration of the timing belt. The posts are provided with angled surfaces located adjacent to the convex surface of the arcuate member to define passageways into which the belt is placed. Ledges at the lower ends of the posts prevent unintended slippage of the belt from the device when the belt is not under tension.
