からの離脱を防止し得る優れた効果を発揮する。Effects of the invention As illustrated in the examples above, this invention bends a part of the running part of the toothed belt in a detour in a U-shape, inserts it between the guide surface and the support member, and Since the teeth of the belt are configured to engage with the engagement teeth provided on the support member, and the engaged state is reliably maintained by the urging force of the pressing means, the number of parts is small and assembly is easy. It has a structure that is easy to install, and also reliably prevents the toothed belt from lifting off from the support member, which tends to occur when the carriage movement is reversed or when the carriage movement suddenly stops.
It exhibits an excellent effect of preventing the toothed belt from separating from the support member during printer operation.
