AI summary

A linear conveyor includes a plurality of modules constituting a conveyance path and a slider that travels along the conveyance path. The linear conveyor includes at least one relay unit disposed across adjacent modules. The modules are configured such that each of the modules has first and second module-side connection sections provided at both ends in a direction along the conveyance path, the modules being connected in a row along the conveyance path. The relay unit includes a first unit-side connection section that is connected to the second module-side connection section of one of a set of the adjacent modules, a second unit-side connection section that is connected to the first module-side connection section of the other of the set of the adjacent modules, and a first circuit that electrically connects the first and second unit-side connection sections to each other.
