A board work machine for performing specified work with respect to a board, the board work machine comprising: a mounting head configured to pick up a component and move the component to a mounting position on the board; a memory section configured to memorize a correction value related to the mounting position of the component and to memorize at least a specific correction value related to the mounting position of a specific component that includes a specified characteristic section on an upper surface of the specific component; an upper imaging device configured to image the component from above; a control device configured to, in a case of performing mounting work of mounting the specific component on the board, acquire a position deviation amount of the characteristic section with respect to the center of the outline of the component based on an upper surface image of the upper surface of the specific component captured by the upper imaging device and control the mounting head to mount the specific component at the mounting position corrected based on the acquired position deviation amount and the specific correction value a lower imaging device configured to image the component from below, wherein the memory section is configured to memorize a non-specific-component-use correction value related to a mounting position of a non-specific component that does not have a specified characteristic section on an upper surface of the non-specific component, and the control device is configured to, in a case of performing mounting work of mounting the non-specific component on the board, acquire a position deviation amount of the non-specific component based on a lower surface image of a lower surface of the non-specific component captured by the lower imaging device and control the mounting head to mount the non-specific component at the mounting position corrected based on the acquired position deviation amount and the non-specific-component-use correction value. a mounting head configured to pick up a component and move the component to a mounting position on the board; a memory section configured to memorize a correction value related to the mounting position of the component and to memorize at least a specific correction value related to the mounting position of a specific component that includes a specified characteristic section on an upper surface of the specific component; an upper imaging device configured to image the component from above; a control device configured to, in a case of performing mounting work of mounting the specific component on the board, acquire a position deviation amount of the characteristic section with respect to the center of the outline of the component based on an upper surface image of the upper surface of the specific component captured by the upper imaging device and control the mounting head to mount the specific component at the mounting position corrected based on the acquired position deviation amount and the specific correction value a lower imaging device configured to image the component from below, wherein the memory section is configured to memorize a non-specific-component-use correction value related to a mounting position of a non-specific component that does not have a specified characteristic section on an upper surface of the non-specific component, and the control device is configured to, in a case of performing mounting work of mounting the non-specific component on the board, acquire a position deviation amount of the non-specific component based on a lower surface image of a lower surface of the non-specific component captured by the lower imaging device and control the mounting head to mount the non-specific component at the mounting position corrected based on the acquired position deviation amount and the non-specific-component-use correction value.
