Abstract
A drive unit is located on an opposite side in relation to an ejecting orifice of a liquid ejecting head unit. The drive unit includes a first board including a first connector coupled to a head connector of the liquid ejecting head unit; and a second board on which a drive circuit configured to generate a drive signal is mounted. The second board is disposed in an upright position with respect to the first board by being B-to-B coupled to the first board, and the drive signal is supplied from the second board to the first connector via the first board.

A drive unit located on an opposite side in relation to an ejecting orifice of a liquid ejecting head unit, the drive unit comprising:
- a first board including a first connector coupled to a head connector of the liquid ejecting head unit;
- and
- a second board on which a drive circuit configured to generate a drive signal is mounted, wherein
- the second board is disposed in an upright position with respect to the first board by being B-to-B coupled to the first board,
- the drive signal is supplied from the second board to the first connector via the first board, and
- the second board has a greater length in a first direction that is an opposite of the ejecting orifice of the liquid ejecting head unit than in both directions orthogonal to the first direction.
A liquid ejecting head unit, comprising:
- a drive unit;
- and
- a head,
- the head including
- an ejecting orifice that, upon receiving a drive signal supplied from the drive unit, ejects liquid from a nozzle provided in a nozzle surface, and
- a collective board that includes a head connector,
- the drive unit being located on an opposite side in relation to the ejecting orifice and including
- a first board including a first connector coupled to the head connector, and
- a second board on which a drive circuit configured to generate a drive signal is mounted, wherein
- the second board is disposed in an upright position with respect to the first board by being B-to-B coupled to the first board,
- the drive signal is supplied from the second board to the first connector via the first board, and
- the second board has a greater length in a first direction that is an opposite of the ejecting orifice of the liquid ejecting head unit than in both directions orthogonal to the first direction.
A liquid ejecting apparatus, comprising:
- a plurality of sets each including a plurality of liquid ejecting head units and a transportation unit, the liquid ejecting head unit including a drive unit and a head,
- the head including
- an ejecting orifice that, upon receiving a drive signal supplied from the drive unit, ejects liquid from a nozzle provided in a nozzle surface, and
- a collective board that includes a head connector,
- the drive unit being located on an opposite side in relation to the ejecting orifice and including
- a first board including a first connector coupled to the head connector, and
- a second board on which a drive circuit configured to generate a drive signal is mounted, wherein
- the second board is disposed in an upright position with respect to the first board by being B-to-B coupled to the first board, and
- the drive signal is supplied from the second board to the first connector via the first board.
