PURPOSE: To reduce the number of required lead wires, by dividing signals into groups.
CONSTITUTION: When an abnormality is detected by a sensor S2, the output level of a signal processing circuit B2 becomes H, the output level of a NOR gate NG becomes L, a stationary contact O of a changeover switch is set at L level, stationary contacts 2, 6 are set at H level and the output level of an OR gate OG becomes L. Then, a motor M rotates a drum DD and a short bar SB. When the short bar SB comes on the stationary contact 2, a signal of H level is entered into a motor drive circuit MDC through a segment Dl and the OR gate OG to stop the motor M. At that time, an indicated item corresponding to the sensor S2 is indicated in a display frame to indicate the abnormality.
