Abstract: A component supplying apparatus includes a motor, a rotating body, a transmitting mechanism, and a predicting section. The rotating body engages with a carrier tape in which a plurality of components to be mounted on a circuit board by a component mounting apparatus are accommodated at predetermined pitches and pays out the carrier tape at the predetermined pitches for supplying the plurality of components. The transmitting mechanism transmits a driving force of the motor to the rotating body. The predicting section predicts a deviation amount of a supplying position of each of the plurality of components based on a model formula expressing a periodical fluctuation of the supplying position of each of the plurality of components that is due to the transmitting mechanism and caused at a time the carrier tape is paid out by the rotating body.

Abstract: A screen printing apparatus includes: a main squeegee that includes a pair of end portions in a width direction and prints, by sliding in a direction orthogonal to the width direction on an upper surface of a screen that is supplied with a paste-like material and on which a hole is formed, the paste-like material on an upper surface of a printing object provided on a lower surface side of the screen via the hole; and a pair of auxiliary squeegees each including a first end portion provided more on an outer side than the end portion in the width direction and a second end portion provided more on an inner side than the end portion in the width direction, the pair of auxiliary squeegees being tilted a predetermined angle with respect to the main squeegee on a rear side of the main squeegee in the sliding direction.
