Abstract:
1. An image forming device comprising: a recording head having a nozzle surface; a carriage that mounts the recording head and is reciprocatable in a first direction; a first guide member having a first sliding surface extending in a horizontal direction; a second guide member having a second sliding surface extending in the horizontal direction, the second guide member being disposed on a downstream side of the first guide member with respect to a second direction orthogonal to the first direction; and an endless belt that extends in the first direction above the second guide member and is movable in the first direction, wherein: the first sliding surface and the second sliding surface slidably support the carriage and extend parallel to the nozzle surface; the carriage is provided with a first protruding member that contacts the first sliding surface and a second protruding member that contacts the second sliding surface; both the first protruding member and the second protruding member protrude downward from a bottom side of the carriage; the carriage and the endless belt are coupled to each other at a coupling point located between the first protruding member and the second protruding member with respect to the second direction; the second guide member has a third sliding surface extending upward in a direction substantially orthogonal to the second sliding surface, the third sliding surface being located between the first sliding surface and the second sliding surface with respect to the second direction; and the carriage includes a third protruding member that slidably contacts the third sliding surface, a fourth protruding member disposed on an opposite side of the third sliding surface from the third protruding member, and an elastic member that elastically urges the fourth protruding member toward the third sliding surface; and the coupling point between the carriage and the endless belt is located between the second protruding member and the third protruding member with respect to the second direction.
