PROBLEM TO BE SOLVED: To inform an operator easily of execution by an indication means of the operation indication of an equipment loaded on a car from the outside of the car cognizably. SOLUTION: When the operation of a door locking device is indicated by a transmitter, the brightness L of the periphery of a car is measured (100, 102). When brightness L reaches a maximum value L1 or more (acknowledgement in 104), a buzzer is rung in large sound volume and information is conducted (110), and the door locking device is worked (118). When measured brightness L extends over a minimum value L2 from the maximum value L1, negation 104 and acknowledgement 106 are informed by ringing the buzzer in intermediate sound volume (112). When measured brightness L reaches the minimum value L2 or less, negation 106 and acknowledgement 108 are informed by a sound and light by ringing the buzzer in small sound volume and lighting a dome lamp (114). |
