Abstract:
1. A recording apparatus comprising: a recording section configured to discharge the liquid; and a transport mechanism configured to transport the recording medium for which an image is recorded by the liquid discharged from the recording section, the transport mechanism including: wherein each of the at least one spur includes a plurality of teeth protruding in a first direction, which is perpendicular to an axis of a rotational shaft of the driven spur as viewed from a direction of the axis, and arranged in a circumferential direction with the axis of the driven spur; each of the teeth includes two side surfaces and a front end surface, each of the two side surfaces inclining to come closer to an imaginary line perpendicular to the axis from a base to a tip of each of the teeth, as viewed from the direction of the axis, the front end surface being formed at a position closer to the axis than a line of intersection of two imaginary planes extending along the two side surfaces; and in a graph, in which a length X (mm) of the front end surface in a second direction, which is an in-plane direction of the front end surface and is perpendicular to both of the direction of the axis and the first direction, is a horizontal axis and an angle Y (degree) between the axis and the imaginary line perpendicular to the guide surface passing through a point of intersection between the axis and the guide surface is a vertical axis, the length X of the front end surface of the driven spur and the angle Y of the driven spur are configured to be within a first area surrounded by mathematical expressions 1 to 6: wherein
