Abstract: A transport-sort conveyor in which a pin of the sliding block of the sort conveyor traveling at high velocity does not cause any trouble at the sorting point and which is suitable for sorting small sized articles is provided. A pusher is provided on any one of the mounting member on one side of the bearing surface defining member and the sliding block to urge the sliding block in the sorting direction while being engaged on one side, and release engagement of the sliding block to be used for sorting operation by the actuating device in the upstream of the sorting point to move the sliding block sideways from the straight-ahead path toward the sorting path. The sliding block that has changed its direction is carried and guided by the sorting guide rail extending from the sorting point in the sorting direction, and thus no movable device such as switch rail or the like is provided at the sorting point.
