Abstract: PURPOSE:To facilitate a proper treatment for improvement of the working state of a controlled device by deciding the degree of the present control output according to a fuzzy rule and producing a warning to urge the change of the fuzzy rule based on the deciding result. CONSTITUTION:A fuzzy inference is carried out with the present control output set to a controlled device used as an input variable. In this case, the membership value of each input variable is obtained at an antecedent part of a prescribed fuzzy rule. The membership value of the present control output is compared with the boundary value by a comparison means. When the former value exceeds the latter value, a warning is produced by a warning generating means 1. Under such conditions, a warning urging the change of a setting range of collection of boards or a warning showing the control limit of the controlled device is selectively produced in accordance with the setting range for collection of boards at a consequent part of the fuzzy rule. Therefore the rule is corrected by a warning if the state is not improved.

Abstract: PURPOSE:To exhaust sheets to different trays from respective exhaust ports by furnishing a direction changeover means downstream an exhaust roller at the outlet from a fixation device, and by actuating interruptive recording when an appropriate signal is given by an interrupt key. CONSTITUTION:Sheet P is exhausted to either of exhaust ports 10j, 10g from a fixation device 9 via an exhaust roller 10a. If an input signal from an interrupt key is entered in a control computer, a displacement solenoid 10k is energized, and an exhaust direction changeover member 10e is moved by an actuator 10l through the action of a spring 10n, and the sheet P is exhausted to the exhaust tray 10j from the exhaust port 10j. In case no input is given by the interrupt key, the solenoid 10k remains off and the changeover member 10e continues to stay in the position shown by solid line, and the sheet P is exhausted from the exhaust port 10g via a guide plate 10c and exhaust roller 10b. This ensures that recording sheets for interruptive and continuous recording are never mixed up.
