PURPOSE:To decrease the number of display elements, to improve the operability, and to reduce the cost by providing number display elements as many as development parts and contents display elements as many kinds as troubles, and turning on those elements. CONSTITUTION:When a trouble occurs to one of the development parts 1-4, the sensor of a development part operates and supplies a signal to a control means 5. The means 5 inputs a signal to a signal processing part through an interface and the signal is processed and stored in a RAM. Then the data is sent back to the processing part a constant time later through the operation of a clock and judges, and the result is displayed on a display means 6. The means 6 is provided with the development number display elements as many as the development parts and the trouble contents display elements as many kinds as the troubles, and the elements are turned on. The total number is the number of the elements, so the number of the elements is decreased, the operability is improved, and the cost is reduced. |
