  • Publication number: 20060000086
    Abstract: Recognition of a position of a printed board is performed both before and after a chip component is mounted on the printed board. When a difference between the positions recognized before and after that is out of a predetermined allowable range, the printed board is treated as a defective. A CPU compares positions of a positioning mark provided on a printed board recognized both before and after a chip component is mounted on the printed board, the positions being taken an image by a board recognition camera and recognized by a recognition processing device. The CPU checks whether or not a difference between the positions is within a predetermined range stored in a RAM, that is, within a range from ?0.100 mm to +0.0100 mm, in both X and Y directions. When judging that the difference is within the range, the CPU controls an electronic component mounting apparatus to stop because of an error.

  • Patent number: 6822767
    Abstract: In a case where minute dirt is lain between light source and an original, since the light source moves in case of the fixing original reading which is an original reading system of reading an original image by fixing the original, the dirt is momently lighted by the light source and influence by the dirt for the read image is appeared in sight by only a minute dot. However, in case of the shifting original reading of reading the original image by shifting the original, since the relationship between the light source and the dirt is in a fixed state, the light source is always to light the dirt and the influence by the dirt for the read image is appeared in sight by a line or a plane. Therefore, in the present invention, edge emphasis degree of edge emphasis processing for the read image data is varied in accordance with a fact that the original reading system is the fixing original reading or the shifting original reading. Accordingly, the influence by the dirt in the shifting original reading can be reduced.
