Abstract: A printing unit includes a carriage, a printing head mounted on the carriage, a guide pillar configured to support the carriage to be reciprocatingly movable in the front-back direction, a unit frame configured to support the guide pillar to be movable in the left-right direction, and a line-feed mechanism configured to move the carriage in the left-right direction. The line-feed mechanism includes a line-feed plate supported by the guide pillar to be movable in the front-back direction and a guide member configured to engage with the line-feed plate and guide the line-feed plate in the left-right direction together with the guide pillar according to the movement in the front-back direction of the line-feed plate. The line-feed plate includes a forward-path engaging section with which the carriage engages in a process from a forward-path start point to a forward-path end point in the front-back direction and a backward-path engaging section with which the carriage engages in a process from a backward-path start point to a backward-path end point in the front-back direction.

Abstract translation: 打印单元包括滑架，安装在滑架上的打印头，构造成支撑滑架能够沿前后方向往复运动的引导柱，构造成支撑引导柱在左侧可移动的单元框架， 以及配置成使托架沿左右方向移动的换行机构。 送线机构包括由导向柱支撑的可沿前后方向移动的行进给板，以及引导构件，其被构造成与线条进给板接合并且引导线条进给板在左右 方向与引导柱一起，根据线条进给板的前后方向的移动。 线路馈送板包括前向通道接合部分，其在从前沿方向的前进路径起点到前进路径终点的过程中与车辆接合，并且后向路径接合部分 滑架从前后方向的后退路径起点到后退路径终点处理。

Abstract: A printing unit includes: a line feed plate moving with a carriage in a line feed operation area; and guide members provided on a unit frame, engaging with the line feed plate, and guiding the carriage and the line feed plate toward one side in a left-right direction as the carriage and the line feed plate move toward one side in a front-back direction in the line feed operation area. Each guide member includes: a line feed guide extending toward one side in the left-right direction as it goes toward one side in the front-back direction and guiding the carriage toward one side in the left-right direction as the carriage moves toward one side in the front-back direction in the line feed operation area; and regulating sections continuing at least to one end in the front-back direction of the line feed guide and regulating the movement of the carriage in the left-right direction.
