Abstract
PURPOSE:To secure normal operation by preventing the cumulated error of an angle of rotation, by returning a CT scanner to the set origin of a scanning operation start position by detecting the absolute position of the CT scanner by the collation of the output signal of a limit switch with the content of a counter. CONSTITUTION:In a CT scanner, when a limit switch LSW 1 or LSW 2 is pushed by the striker 51 of a CT scanner rotating plate 5, a scanning operation start signal S is inputted to the CPU 11 of a control apparatus 1. The CPU 11 drives a DC motor 2 on the basis of said signal S and the CT scanner rotating plate 5 is rotationally moved in a direction (a) or (b) through a speed reducer. The absolute position of the striker 51 of the CT scanner rotating plate 5 can be detected by the collation of the signal of the LSW 1 with the content of a counter 17 and the start position of scanning in the direction (a) in the LSW 1 can be initially set each time. Even when the CT scanner rotating plate 5 is stopped at an erroneous position, said CT scanner rotating plate 5 can be stopped at a normal position by initial setting and the cumulated error of an angle of rotation caused by the repetition of the scanning operation of the CT scanner in the directions (a), (b) can be removed.
