Abstract
A platen conveyance device includes a first conveyance path, a platen supporter, a second conveyance path, and a positioner. The first conveyance path is configured to convey a platen to a pretreatment device. The platen supporter is configured to support the platen conveyed by the first conveyance path. The second conveyance path is provided with the platen supporter. The second conveyance path is configured to convey the platen supporter to a printer. The positioner is configured to position the platen supported by the platen supporter at a prescribed printing position in a first direction in a horizontal direction.
