PURPOSE:To position and adjust the change of arrangement for television cameras with short time and high reproductiveness by providing each measuring head in matrix shape and also forming such constitution as to drive each of said measuring heads symmetrically each other in respect to the center line and the center column. CONSTITUTION:Since a center measuring head 2e is accorded with the center 26a of a cathode ray tube in the state of mounting the cathode ray tube in position, firstly, measuring heads 2a, 2b, 2c, 2g, 2h, 2i are moved symmetrically in respect to the center axis along the direction of the center axis X to align each column of all measuring heads with each column of measuring points by driving the motor 45 of a forward and backward driving mechanism 3. And thereafter, the measuring heads 2a, 2c, 2d, 2f, 2g, 2i are symmetrically rotated in respect to the center axis X each other in a vertical surface by driving the linear motor 55 of an angular driving mechanism 4 and the arrangement is completed by slanting them so as to enable optical axis 20 of each mesuring head to pass through the opposite measuring point. |
