In an electronic component feeding apparatus for feeding components with use of a taping component, a brushless motor is used as a drive motor in a tape sending mechanism that transports the taping component so as to improve productivity in an electronic component mounting apparatus equipped with the electronic component feeding apparatus. Also, an electronic component feeding apparatus is provided with a control part that automatically executes initial processing such as sending of the taping component, as well as detects and reports a sending failure of the taping component when the electronic component feeding apparatus is installed in the electronic component mounting apparatus, which makes it possible to provide an electronic component feeding apparatus enabling easy and prompt detection of the sending failure of the taping component.

To provide an image processing device capable of reducing a user operation in production of motion data by simulating a 3D motion of a moving object. A base data obtaining unit obtains a plurality of base data each containing an image and distance data indicating a distance between an object shown in the image and the image capturing unit, the distance data being based on a measured result. An in-image position specifying unit, based on the image obtained, specifies a position in the image, where the moving object is shown. A distance specifying unit specifies a distance between the moving object and the image capturing unit, based on the specified in-image position and the distance data. A position coordinate calculating unit calculates the 3D position coordinates of the moving object, based on the specified in-image position and the specified distance. The motion data producing unit produces motion data describing a motion of the moving object in the 3D space, based on the calculated 3D position coordinates.

摘要:
A metal scuff plate includes a plate made from a light-alloy and having a back side, at least one pin positioned at a portion of the back side of the plate and welded thereto. The at least one pin possesses an engagement groove. The metal scuff plate further includes a synthetic-resin made clip having at least one first hook engaged with the engagement groove of the pin. The clip is engaged with at least one engagement hole defined at a body so as to fasten the light-alloy plate to the body.
