An apparatus for conveying and positioning a substrate of a printed-wiring board, comprising: a conveyor system for transferring the substrate, including a pair of parallel spaced-apart side frames at least one of which is movable relative to the other; a positioning device including a support member, a pair of parallel spaced-apart holder members disposed on the support member and movable relative to each other so as to be engageable with opposite sides of the substrate parallel to the side frames, to thereby hold the substrate, and a device for moving the support member along X and Y axes, so as to position the substrate within a predetermined area; a device for moving the support member between an aligned position in which the holder members are aligned with the side frames, and an unaligned position for positioning the substrate in the predetermined area; and a device for connecting the movable holder member and the movable side frame when the support member is in the aligned position. The distance between the holder members is variable with a change in the distance between the side frames. |
