Abstract: The invention provides a mounting apparatus with a beam which is free from adverse effect on its performance due to thermal distortion and misalignment of its guide rails, on which the beam for mounting operation travels. One end of the beam is rotatably supported on a slide, which moves along the guide rails. Another end of the beam is also rotatably supported on another slider through a moving element. The slider and the mounting element move along the guide rail. The moving element moves in a direction perpendicular to the guide rails.

Abstract: A recognition camera images an electronic component, and a recognition processing unit performs recognition processing of the electronic component based on the result of the imaging. The recognition processing is performed using the component data of group 1 data, group 2 data, group 3 data, and group 4 data that are stored for the images taken in a random access memory (RAM). The group 1 data is used for lead inspection (for inspecting positioning error and bending of the lead), the group 2 data and the group 3 data are used for calculating amounts of adjustment in the X and Y directions, and the group 4 data is used for calculating the amount of adjustment in the &thgr; direction. This makes it possible to mount accurately components with pins and extrusions extruded from the molding, such as connectors, such that the pins and extrusions are accurately engaged with the holes formed in a print board.

Abstract: In a component feeding apparatus, forwarding pitches of the storage tape are reduced without using an alternative forwarding gear corresponding to the reduced pitches. The component feeding apparatus feeds chip components by intermittently forwarding the storage tape having the chip components by predetermined pitches. Thy apparatus has a sprocket for intermittently forwarding the storage tape, a forwarding gear supported by the same axis as that of the sprocket and rotating together with the sprocket, a forwarding lever turnably supported, and first and second forwarding pawls both attached to the forwarding lever. Every time the forwarding lever turns in a predetermined direction, the first forwarding pawl and the second forwarding pawl engage with the forwarding gear alternately to rotate the forwarding gear by half a tooth pitch.
