Base-material drying device and printing device

A base-material drying device for drying ink adhering to a first surface of a continuous base material having a long band-like shape, the base-material drying device comprising:

• a first transport mechanism that transports the continuous base material from upstream to downstream along a predetermined transport path;
• and
• a first heating mechanism that heats the continuous base material transported by the first transport mechanism, wherein
• the first transport mechanism includes:
• a first transport supporter that supports, in a first position in a first direction, the continuous base material that is transported to one side in a second direction intersecting with the first direction;
• a second transport supporter that is arranged downstream of the first transport supporter and that supports, in a second position away from the first position in the first direction, the continuous base material being transported from the first transport supporter to one side in the first direction to be transported to the other side in the second direction;
• and
• a third transport supporter that is arranged downstream of the second transport supporter and that supports the continuous base material in a third position in the first direction while bending the continuous base material being transported from the second transport supporter to the other side in the first direction so that the continuous base material is transported in a third direction intersecting with the first direction and the second direction,
• the first heating mechanism is capable of heating part of the continuous base material in a position on the transport path between the first transport supporter and the third transport supporter,
• the first transport supporter, the second transport supporter, and the third transport supporter are located on a second surface side of the continuous base material opposite to the first surface,
• throughout an entirety passage in which the continuous base material is transported from the first transport supporter to the third transport supporter, the first surface of the continuous base material is maintained in a non-contact state with the first transport supporter, the second transport supporter, and the third transport supporter,
• the first transport mechanism further includes a fourth transport supporter that is arranged downstream of the third transport supporter and that supports the continuous base material in a fourth position in the first direction while bending the continuous base material so that the continuous base material is transported to the one side in the second direction,
• the fourth transport supporter is arranged on the second surface side of the continuous base material,
• the transport path includes:
• a first path that is part of a path from the second transport supporter to the third transport supporter;
• and
• a second path that is located downstream of the fourth transport supporter and that extends in parallel with the first path,
• the second path is located away from the first path in the third direction, and
• the first heating mechanism includes a heater capable of heating a portion of the continuous base material on the first path and a portion of the continuous base material on the second path at the same time.
