1. An electric wire printing device, comprising:
an inkjet head injecting ink to perform printing on an electric wire;
a transportation device transporting the electric wire; and
a drying device provided downstream, in a transportation direction of the electric wire, with respect to the inkjet head, the drying device blowing air toward a printed portion on the electric wire; wherein
the transportation device transports the electric wire in a longitudinal direction of the electric wire;
the drying device includes a tubular member provided so as to surround a transportation path of the electric wire;
an inner space is provided in the tubular member through which the electric wire is to pass; and
the tubular member includes:
a large area portion demarcating an upstream portion of the inner space in the transportation direction of the electric wire and including an entrance opening through which the electric wire is inserted, the entrance opening being provided at an upstream end of the upstream portion;
a small area portion demarcating a downstream portion of the inner space in the transportation direction of the electric wire and including an electric wire exit through which the electric wire exits, the electric wire exit being provided at a downstream end of the downstream portion and having an opening area that is smaller than an opening area of the entrance opening;
a tapering portion demarcating an intermediate portion of the inner space between the large area portion and the small area portion and having a tapering shape which has a cross-sectional area decreasing toward the small area portion; and
a supply inlet opens toward the large area portion to allow compressed air to be supplied therethrough.
