摘要： PROBLEM TO BE SOLVED: To provide a vehicle shape measuring device and its method by which the shape of the wheel of a travelling vehicle can be measured with good precision. SOLUTION: The contours of the rail contact portion and the flange portion of the wheel 2 of a travelling vehicle 1 are photographed by a contour photographing means (a CCD camera 4a), and the outside diameter of the wheel 2 of a travelling vehicle 1 is detected by an outside diameter detection means (a CCD camera 8a) so as to respectively obtain contour image information and outside diameter information. Since various blurring is contained in the image information, the same is corrected by a blurring correction means (an x, y, z correction portion 11a), and the wheel shape is obtained by an image processing means (an image processing portion 11) based on the corrected image information.

摘要： PURPOSE:To shorten the modifying time of a printed wiring board by extracting all remaining conductors after inputting a photographed circuit pattern to a labeling circuit and expanding and contracting the circuit pattern with a logical filter and extracting harmless remaining conductors. CONSTITUTION:The circuit pattern of a printed wiring board 1 photographed with a camera 10 is inputted to a labeling circuit 11 and logical filter 12 and the circuit 11 only extracts remaining conductors 4 and 5 which do not exist in a reference picture. Both sides of the circuit pattern inputted to the filter 12 are expanded by the half of an allowable creep distance specified by a standard. Then the remaining conductor 4 is connected with the expanded section of a conductor 2 at the expanded section, but, when the expanded section is contracted to the original width, the remaining conductor 4 becomes a remaining conductor which connects the upper and lower conductors 2. Then the pattern is inputted to a labeling circuit 13 and only the remaining conductor 5 is extracted and a deciding section 14 takes out the conductor 5 from the remaining conductors 4 and 5 extracted by the circuit 11 to extract only the conductor 4 which may short-circuit the conductors 2 with each other and does not match the standard. Therefore, the modifying time of the board 1 can be shortened.

摘要： PURPOSE:To enable a line sensor to fetch the image of a part even when the moving speed of a mounting head becomes higher. CONSTITUTION:A substrate carrying path 14 along which a substrate 13 is carried and a part supplying section 16 provided with a plurality of tape feeders 19 are provided on the base 12 and a mounting head 21 which is freely moved by means of an X-Y robot 22, is provided above the section 16. A line sensor 23 which detects the position of a part 15 is provided between the path 14 and section 16 so that the sensor 23 can be moved in the Y-axis direction by means of a Y-axis moving unit 24. When the head 21 receives the part 15 from the section 16 and moves the part 15 to the substrate 13, the sensor 23 picks up the cut image of the parts 15 extended in the X-axis direction at a plurality of number of times while the sensor 23 is moved in the Y-axis direction. The positional deviation of the part 15 is detected based on the image data and the mounting work is performed by correcting the position of the part 15.

CONSTITUTION:An image of a part 11 obtained by a transfer head is picked up by an imaging means 16 during its transfer. A position of the part 11 is recognized by a recognition means based on image data acquired by the imaging means 16. In the process, a recognition mark 14 is fixedly provided to a transfer head and the imaging means 16 picks up also an image of the recognition mark 14 together with an image of the part 11.

摘要： PURPOSE:To mount a part on a board with accuracy by detecting difference in temperature between the part and its surroundings to recognize the external form of the part. CONSTITUTION:An electronic part 4 is sucked and held by a suction nozzle 31 at its lower end, and then is transported along the alternate long and dash line in the figure. The electronic part 4 is temporarily stopped direct above an infrared camera 13 on the way to a board 1. The temperature detection signal from the infrared camera 13 is processed in a signal processing equipment 14. Only objects whose temperature is almost equal to that of the equipment's surroundings are displayed on the monitor 15a of a computer 15. The computer 15 calculates the position and posture of the electronic part 4. The rotary driving equipment equipped on an electronic part mounting head 16 is actuated according to the command from the computer 15, and rotates the suction nozzle 31 through a required angle to thereby correct the posture of the electronic part 4. Then the mounting head 16 mounts the electronic part 4 on the printed board 1.

摘要： PURPOSE:To enable measurement of a crystal defect with a high throughput by providing a photosensor having a light-sensing surface being perpendicular to the direction of bending reflection which is different from the direction of regular reflection of a light beam on a complete specular surface and specific to a section gradient of the defect. CONSTITUTION:A scanning direction 9 of a laser beam being parallel to the orientation flat 6 of an Si wafer is made the direction of the axis X, while the direction of an oxidation-induced defect 5 being perpendicular to the orientation flat 6 is made the direction of the axis Y. On the occasion when beam scanning is executed in the direction of the axis X in which the defect 5 exists, an angle of incidence of an incident light 7 is made thetai. When the beam is cast on the defect 5 it is bent by an angle 2theta to the direction of the axis Y by a gradient theta (which is a section gradient of a crystal transformation defect and has uniformity) and reflected. By disposing light-sensing parts 10a and 10b on extensions of reflected lights 8a and 8b deviating by angles + or -2theta from a plane Y-Z in respect to an angle thetai of reflection on this plane, so that the light-sensing surfaces thereof are positioned perpendicularly thereto, only the reflected lights by the defect 5 can be sensed. As to a diffusedly reflected light by a particle or the like, it is advisable to provide a large light-sensing part additionally for receiving it.
