摘要： PROBLEM TO BE SOLVED: To provide a device for specifying positional information, enabling an image pickup device to easily read correct positional information of each of positions in a three-dimensional space.
SOLUTION: In this device for specifying positional information device 1, a plurality of laser beam irradiating means 5 each capable of moving the irradiation direction of a laser beam with a universal joint are disposed on the peripheral surface of a casing 3. Consequently, since the laser beam has an exposure point S having a luminance higher than that of surroundings, the distance from to the point S can also be measured with high accuracy, even if the distance is measured by automatic focus detecting method.

摘要： PURPOSE: To automatize a device by controlling the rotational speed of a motor so that the force for pushing out a tube from a straightening device to bending work becomes the sum of force opposing to the reaction force by restraining a straight tube at the time of bending and force for pushing the straight tube from behind. CONSTITUTION: When straightening speed S. is commanded, a coil-shaped long size tube L is pulled in with a motor 5 whose rotational speed is controlled with a computer system 6, straightened into a straight tube with V-straightening rollers 2-1 and H-straightening rollers 2-2 and pushed into a bending device 3. The force P1 for pressing the straight tube from the upside of a die and the force for pushing the straight tube from behind are applied to the straight tube. To continue the working by connecting the straightening device 2 and the bending device 3, it is necessary that the straightening speed S1 and bending speed S2 are equal and the rotational speed control of the motor 5 is executed with a computer controller 6 so that the force F for pushing out the tube to the bending work becomes (P1 +P2 ). In this way, by integrally connecting processes, the device is automatized and working is made efficient.
