Abstract
A liquid discharge apparatus includes a liquid discharge head including a nozzle face in which a nozzle is formed and configured to discharge a liquid, a carriage on which the liquid discharge head is mounted, and a guide shaft configured to hold the carriage movably. The liquid discharge apparatus further includes a driver configured to move the carriage, and a coupling between the carriage and the driver. The coupling is disposed on an axis of the guide shaft in a direction orthogonal to the axis of the guide shaft.
Claims8
A liquid discharge apparatus comprising:
- a liquid discharge head including a nozzle face in which a nozzle is formed and configured to discharge a liquid;
- a carriage on which the liquid discharge head is mounted;
- a guide shaft to hold the carriage movably;
- at least one bearing in which the guide shaft is movably fitted;
- a driver to move the carriage, the driver including a crank coupled to the carriage;
- and
- a coupling between the carriage and the crank, the coupling disposed on an axis of the guide shaft in a direction orthogonal to the axis of the guide shaft,
- wherein, in an axial direction of the guide shaft, the coupling is disposed between both ends of the at least one bearing, or the at least one bearing includes two bearings and the coupling is disposed between the two bearings in the axial direction of the guide shaft, and
- the liquid discharge apparatus further comprises an elastic structure disposed between the carriage and a fixed portion of the liquid discharge apparatus, the elastic structure being disposed to pull the carriage obliquely downward with respect to the axis of the guide shaft.
