Claims

[Claims for Utility Model Registration] (1) A guide means for guiding a frame onto a bonding stage where bonding work is performed, and a conveying surface of the guide means arranged in parallel with the height of the frame guide surface, which is approximately the same height as the frame guide surface. a frame supply conveying means arranged in a direction parallel to the frame guiding direction of the guiding means, and a conveying means provided in parallel with a plurality of conveying mechanisms capable of conveying frames in a direction parallel to the frame guiding direction of the guiding means, The plurality of transport mechanisms are configured to be movable in a direction orthogonal to the direction, and the plurality of transport mechanisms can be moved back and forth so that at least one frame guide surface is at approximately the same height as the frame guide surface of the guide means and lower than the frame supply transport means. A frame conveyance switching mechanism characterized by comprising a switching means for switching to a frame. (2) The frame conveyance switching mechanism according to claim 1, wherein the switching means is formed of a cam.
