A rollover judging device adjusts the magnitude of an angular velocity component ω of a vehicle in a direction of a rollover, which is measured by an angular velocity sensor 1, by using an ω adjusting unit 3c on the basis of an acceleration component of the vehicle in its rightward or leftward direction or in its upward or downward direction, which is measured by an acceleration sensor 2, calculates an angle component θo by integrating with respect to time this adjusted angular velocity component ωo by using an integrator 3d, carries out predetermined multiplication and addition processes by using a judging means 4 on the basis of this angle component θo and the measured angular velocity component ω, and, when the result of this addition process exceeds a preset threshold Th, outputs a signal indicating judgment of occurrence of a rollover to an air bag control device 5.

In an array of dies (31) on a dicing sheet (34), a plurality of reference dies (45) images of which are recognizable are arranged at predetermined distances. In the case where a distance from a position of a die (31(a)) adsorbed this time to a position of a die (31(b)) to be adsorbed next that is estimated according to the position of the die (31(a)) adsorbed this time is equal to or greater than a predetermined value, the position of the die (31(b)) to be adsorbed next is recognized, and in addition to this, a reference die (45) close to the die (31(b)) to be adsorbed next is selected from a plurality of reference dies (45) and an image of the selected reference die (45) is picked up by a camera (42) so that the position of the reference die (45) is recognized. Based on the position relationship between the recognized position of the reference die (45) and the recognized position of the die (31(b)) to be adsorbed next, whether or not the recognized position of the die (31(b)) to be adsorbed next is a position of a correct die (31(c)) to be adsorbed next is determined. If it is determined that the recognized position of the die (31(b)) to be adsorbed next is not the position of the correct die (31(c))to be adsorbed next, the position of the die (31(c)) to be adsorbed next is re-estimated with reference to the recognized position of the reference die (45), an image of the die (31(c)) is picked up by the camera (42) so that the position of the die (31(c)) is recognized, and a pushing-up operation and an adsorption operation are executed.

When a plurality of image-recognizable fiducial dies 45 are disposed at predetermined intervals in an arrangement of dies 31 on a dicing sheet 34, and an interval from a position of a die 31(a) which is subjected to a present adsorption operation to an estimated position for a next adsorption die 31(b) is equal to or greater than a predetermined value, in addition to recognizing the position for the next adsorption die 31(b), a fiducial die 45 adjacent to the next adsorption die 31(b) is selected from the plurality of fiducial dies 45, the fiducial die 45 is imaged by a camera 42, a position of the fiducial die 45 is recognized, and it is determined whether or not a recognition position for the next adsorption die 31 (b) is a proper position for a next adsorption die 31 (c) based on a positional relationship between a recognition position of the fiducial die 45 and the recognition position for the next adsorption die 31(b). When it is determined that the recognition position for the next adsorption die 31 (b) is not the proper position for the next adsorption die 31(c), the position of the die 31(c) to be adsorbed next is reestimated based on the recognition position of the fiducial die 45, the die 31(c) is imaged by the camera 42, the position of the die 31(c) is recognized, and push-up operation and adsorption operation are executed.
