Ink-jet recording apparatus

摘要

An ink-jet recording apparatus includes: a base member; a conveyor unit for conveying a sheet in a first direction; and a recording unit for ejecting ink when opposed to a sheet in a second direction. The base member includes: a first side base portion; a second side base portion; a center base portion located between the first side base portion and the second side base portion in a third direction; first and second side walls extending in the first direction and projecting in the second direction from opposite edge portions of the center base portion in the third direction; and a main board connecting the first side wall and the second side wall and configured to support the conveyor unit and the recording unit. The main board is greater in stiffness than the first side wall and the second side wall.

主权项

1. An ink-jet recording apparatus comprising:
a base member made of resin material; a conveyor unit supported by the base member and configured to convey a sheet in a conveying direction that is parallel to a first direction; and a recording unit supported by the base member and configured to eject ink to record an image on the sheet in a state in which the recording unit is opposed to the sheet in a second direction perpendicular to the first direction; wherein the base member comprises:
a first side base portion and a second side base portion each extending in the first direction and spaced apart from each other in a third direction that is perpendicular to each of the first direction and the second direction;a center base portion located between the first side base portion and the second side base portion in the third direction;a pair of side walls opposed to each other in the third direction and comprising
(i) a first side wall extending in the first direction and projecting in the second direction from an edge portion of the center base portion near the first side base portion in the third direction; and(ii) a second side wall extending in the first direction and projecting in the second direction from an edge portion of the center base portion near the second side base portion in the third direction; anda connecting member connecting the first side wall and the second side wall to each other and configured to support the conveyor unit and the recording unit; wherein the ink-jet recording apparatus further comprises:
a pair of metal walls supported by the connecting member and spaced apart from each other in the third direction; anda guide rail supported by the pair of metal walls and extending in the third direction, wherein a stiffness of the connecting member is greater than that of each of the first side wall and the second side wall; wherein the recording unit comprises:
a carriage supported by the guide rail and reciprocated in the third direction; anda recording head mounted on the carriage and configured to eject ink from a plurality of nozzles; and wherein the conveyor unit comprises:
a conveyor roller supported by the pair of metal walls at a position located upstream of the recording head in the conveying direction; andan output roller supported by the pair of metal walls at a position located downstream of the recording head in the conveying direction.
