PURPOSE:To simplify and transfer and to reduce the number of interface circuits by equipping the title machine with a main CPU and a sub CPU which carries out all control in relation to variable power functions. CONSTITUTION:The main CPU is mounted on a main substrate 13, while the sub CPU is mounted on a variable power controlling substrate 14. The main CPU controls the read and display for various key input not related to the variable power functions through a first operation display board 15. On the other hand, the sub CPU performs the read and the display for key input related to variable power through a second operation display board 23. As a result, the transfer of data is minimized between the main and the sub CPUs. The data transfer is thus simplified, and the number of the interface circuits can be thereby reduced. |
