Abstract: Provided is a user interface apparatus capable of controlling a change speed of a parameter with respect to a user's setting operation. A gauge volume is set according to the setting operation, such as a drag operation, accompanying with change of an operated position Pa operated by the user. The user interface apparatus is provided with a device which is configured to change the set value Pg of the gauge volume according to the change amount ?Y of the operated position Pa, and in the device further provided is a device which is configured to change according to the elapsed time t from a predetermined reference time set in relation to the setting operation, a criterion value Vc which determines the relation between the change amount ?Y of the operated position and the change amount of the set value Pg of the gauge volume.

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.
