(54) Wiring structure, heater driving device, measuring device, and control system


(57) The number of wirings and the number of switching elements are decreased in a heater, a sensors, and the like. First to ninth heaters that heat a hot plate are connected into a matrix form between first power lines in a row direction and second power lines in a column direction. The first power lines are connected to one end of a power supply through three switching elements, respectively. The second power lines are connected to the other end of the power supply through three switching elements, respectively. On-off control is performed to the switching elements to select the heater to be driven. Therefore, the number of power lines and the number of switching elements are decreased compared with a conventional technique in which the heaters are separately wired.
