1. A drive circuit unit that drives a head including a discharge section discharging, based on a drive signal, a liquid from a nozzle in a first direction, the drive circuit unit comprising:
a fan; and
a power supply board disposed on a side in a second direction opposite to the first direction with respect to the head, supplying power to a drive circuit generating the drive signal, and having a first surface on which the fan is mounted, wherein
a height of a first object, which is a highest of objects mounted on the first surface in a direction orthogonal to the first surface, is equal to or less than a length of the head in a transport direction, and
the first surface is a surface parallel to the first direction or a surface oblique to the first direction.
