1. An article transport vehicle, comprising:
a travel unit that travels to a set position that has been set so as to correspond to each of a plurality of storage units configured to store an article;
a support portion configured to support an article;
a lighting unit that emits light; and
a control unit that controls the travel unit and the lighting unit;
wherein the plurality of storage units includes at least one target storage unit, and the at least one target storage unit is a removal source where an article to be supported in the support portion is being stored, or the at least one target storage unit is a storage destination where an article being supported in the support portion is to be stored,
wherein the control unit executes a travel control that controls the travel unit such that the travel unit travels to the set position that has been set to correspond to the target storage unit, and the control unit further executes a lighting control that controls the lighting unit to emit light to a lighting position that corresponds to the target storage unit
wherein each of the storage units is provided with an opening face having an opening portion where an article is inserted or removed,
wherein the plurality of storage units are arranged with their opening faces facing in the same direction,
wherein in a vertical direction view viewed in a vertical direction, where the direction in which the plurality of storage units are arranged is an arrangement direction, a side where a worker performs work relative to the support portion in the arrangement direction serves as a working side,
wherein the set position is set on an opposite side to the working side with respect to the target storage unit,
wherein the lighting unit emits light in a direction that, in the vertical direction view, is inclined with respect to a direction orthogonal to the arrangement direction, and is directed more toward the working side as the light moves to a storage unit side, and
wherein the lighting unit is further configured to emit light to display number information indicating a number of articles to be removed from the target storage unit at the lighting position, and-the control unit executes the lighting control, and controls the lighting unit to display the number information at the lighting position.
 
7. An article transport vehicle, comprising:
a travel unit that travels to a set position that has been set to correspond to each of a plurality of storage units configured to store an article;
a support portion configured to support an article;
a lighting unit that emits light; and
a control unit that controls the travel unit and the lighting unit;
wherein the plurality of storage units includes at least one target storage unit, and the at least one target storage unit is a removal source where an article to be supported in the support portion is being stored, or the at least one target storage unit is a storage destination where an article being supported in the support portion is to be stored,
wherein the control unit executes a travel control that controls the travel unit such that the travel unit travels to the set position that has been set to correspond to the target storage unit,
wherein
the plurality of storage units are arranged in a state lined up in the vertical direction,
wherein the lighting unit is configured to emit light to display position information indicating the position of the target storage unit in the vertical direction,
wherein the control unit further executes a lighting control and controls the lighting unit to emit light to a lighting position and to display the position information at the lighting position, and
wherein the lighting position corresponds to the target storage unit and is set on a floor where the travel unit travels, and
wherein the lighting unit is further configured to emit light to display number information indicating a number of articles to be removed from the target storage unit at the lighting position, and the control unit executes the lighting control, and controls the lighting unit to display the number information at the lighting position.
