An apparatus for conveying a circuit substrate, including: two belts which are provided at respective positions apart from each other in a first direction, and which include respective flat portions extending parallel to each other in a second direction perpendicular to the first direction; two substrate guides one of which extends over one of opposite sides of the flat portion of a corresponding one of the two belts, and the other of which extends over one of opposite sides of the flat portion of the other belt, the one side of the flat portion of the one belt being remoter from the other belt than the other side of the flat portion of the one belt in the first direction, the one side of the flat portion of the other belt being remoter from the one belt than the other side of the flat portion of the other belt in the first direction, the two substrate guides having respective guide surfaces opposite to each other; the respective other sides of the respective flat portions providing respective substrate-convey portions; and each of the respective substrate-convey portions including at least one support projection, respective upper ends of the respective support projections cooperating with each other to define a substrate-support plane, the substrate-support plane being higher than respective lower edge lines of the two guide surfaces and being lower than respective upper edge lines of the two guide surfaces.

[ What is claimed is:] [1.] An apparatus for conveying a circuit substrate; comprising;two first rotatable members;two second rotatable members;a first belt which is wound on the two first rotatable members and includes a substantially horizontal, flat portion extending between the two first rotatable members;a second belt which is wound on the two second rotatable members and includes a substantially horizontal, flat portion extending between the two second rotatable members;the first and second belts being provided at respective positions apart from each other in a first direction, the respective substantially horizontal, flat portions of the first and second belts extending parallel to each other in a second direction perpendicular to the first direction, the first and second belts being circulated such that the two flat portions thereof are moved at a same speed and in a same direction;a first substrate guide which extends over an outside portion of the flat portion of the first belt, the outside portion of the flat portion of the first belt being remoter from the second belt than an inside portion of the flat portion of the first belt in the first direction;a second substrate guide which extends over an outside portion of the flat portion of the second belt, the outside portion of the flat portion of the second belt being remoter from the first belt than an inside portion of the flat portion of the second belt in the first direction, the first and second substrate guides having respective guide surfaces opposite to each other;the respective inside portions of the respective flat portions of the first and second belts providing respective substrate-convey portions which support opposite end portions of the circuit substrate and which convey the circuit substrate while opposite end surfaces of the circuit substrate are guided by the respective guide surfaces of the first and second substrate guides; andeach of the respective substrate-convey portions of the first and second belts including at least one support projection which projects upward from an upper surface of said each substrate-convey portion, respective upper ends of the respective support projections of the two substrate-convey portions cooperating with each other to define a substrate-support plane on which the support projections support the circuit substrate, the substrate-support plane being higher than respective lower edge lines of the two guide surfaces and being lower than respective upper edge lines of the two guide surfaces.
