Abstract
Provided is 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 including: 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, and having a first surface on which the fan is mounted, in which 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.

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.
A head unit comprising:
- a head including a discharge section discharging, based on a drive signal, a liquid from a nozzle in a first direction;
- and
- a drive circuit unit driving the head, wherein
- the drive circuit unit includes
- 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,
- 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.
A liquid discharge apparatus comprising:
- a transport unit transporting a medium;
- a head including a discharge section discharging, based on a drive signal, a liquid from a nozzle in a first direction;
- and
- a drive circuit unit driving the head, wherein
- the drive circuit unit includes
- 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,
- 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.
