Abstract: A transfer pathway of a mounting head 10 in a component-mounting round during which the mounting head 10 moves back and forth between a component feeding unit 4 and a substrate conveyance mechanism 2 is derived by a transfer pathway calculation unit 25 for each component-mounting round from mounting program data 21a. A focusing processing unit 24 controls an optical system focusing mechanism 18, thereby matching a focusing point of a line sensor camera 14 achieved during imaging operation to the transfer pathway of the mounting head 10 based on data pertaining to the derived transfer pathway. Further, an optical system zooming mechanism 17 adjusts an imaging range according to the focusing point. Accordingly, even when a long substrate 3 is taken as an object, it is possible to detect with high precision whether or not a component exists on the pickup nozzle 11 of the mounting head 10.

On the basis of data pertaining to the thus-derived transfer pathway, image data output from a line sensor camera assigned to a head transfer range segment that the transfer pathway of the mounting head 10 crosses in each of component-mounting rounds are selected and captured by an image selection processing unit 24. The image data output from the line sensor camera whose focusing point substantially matches the imaging target can be used for detecting whether or not a component still exists.

Abstract: An image generation method for distinguishing a shape of a component includes: a color image taking step (S101) of taking an image of the component in color, and a conversion step (S102, S104) of converting the color image taken in the color image taking step (S101) into a black-and-white grayscale image in which the shape of the component is shown in black-and-white grayscale.

Abstract: An apparatus has a holder that receives a component from a component supply and then places the component on a substrate. In operation, it is determined whether the holder would make an interference with another component already mounted on the substrate. If this judgement is affirmative, mounting of the component held by the holder is prohibited. If, on the other hand, this judgement is negative, the component held by the holder is mounted onto the substrate.

Abstract: In an electronic component mounting method and apparatus, an electronic component is taken out from an electronic component feed position, a posture of the component is detected, and the component is mounted on a board based on a detected result. The method includes acquiring image data with a camera of the component from the feed position, processing acquired image data with a plurality of algorithms for detecting postures of components, and detecting a posture of the component.

Abstract: An electronic component mounting apparatus (1) includes a device for illuminating a mark (9) on a printed circuit board (14) for recognition. The illumination device (10) includes a light path adjustable member (5). This light path adjustable member (5) is disposed between an illumination source unit (2) and the object (9) to be illuminated. At least one of the light incidence side and the emission side of the light path adjustable member (5) is divided into a plurality of subareas (6), (7), (8), each having a different index of refraction. Each of the subareas (6), (7), (8) emits light at a respective different index of refraction. The emitted light can be collected on a specific area containing the object (9), and appropriate illumination light can thus be emitted to the object (9).

Abstract: Improved apparatus for collecting effluent oil floating on a water surface. The improvements exist in that the apparatus utilizes a pair of side plates disposed in a forwardly opened arrangement, a weir which is inclined in a rear-downward direction with its opposite side edges contacted to the inner wall surfaces of the side plates under the water surface, and a slant plate which has its rear end positioned above the rear end of the weir in the rear of said side plates and has its opposite side edges fixedly secured to the inner wall surfaces of the side plates. Also, an oil leakage preventing plate is positioned midway between the rear end of the weir and the rear end of the slant plate and has its opposite side edges fixedly secured to the inner wall surfaces of the side plates to form a water discharge port between the oil leakage preventing plate and the rear end of the weir and to form an oily water intake port between the oil leakage preventing plate and the rear end of the slant plate.
