Abstract
PURPOSE: To supply no power to a power transformer except during the use of an apparatus and heighten the safety and reliability, by connecting a switch in series to the primary side of the power transformer.
CONSTITUTION: When the apparatus is not used, the switdh 15 and a non-locked switch 14 are open. Thus, the power transformer is not energized and no voltage is applied to a control circuit 10. Thereby, the reliability and safety of the control circuit are heightened.
