<P>PROBLEM TO BE SOLVED: To provide a substrate conveyance apparatus that can uniformly press even a printed substrate with a small length in the conveyance direction to the engaging part of a conveyance chute from the lower side. <P>SOLUTION: When a substrate conveyance chute stops lowering, an air cylinder 15 corresponding to the size of a printed substrate P is activated to take in a rod. A pressing member is decided according to a guide member 16 against the energizing force of a coil spring. For a printed substrate P with small length in the conveyance direction, only a pressing member 10A is used, and when the length is ordinary, the pressing members 10A and 10B are used, and when the length is large, the pressing members 10A, 10B and 10C are raised to press down the printed substrate P to the engagement part of the substrate conveyance chute from the lower side, so as to position the printed substrate P in the vertical direction. In this case, in the pressing member 10A corresponding to the printed substrate P with small length, each of cylinders 15 is located outside the respective guide members 16 at the end of the positioning reference side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
