To easily arrest a criminal by letting a fleeing criminal pass through inside a room exit booth which is a closed area and shutting him/her up inside the room exit booth at the time.

In the case that a crime act of robbery or the like occurs inside a bank X, a special activation button is operated and the electric locks of respective door parts are respectively locked and unlocked by command signals from a control means. That is, the primary door part 1a of a room entrance booth 1 for repeating locked/unlocked states at normal time is switched to the locked state in the case that a room presence confirmation sensor 8 does not output detection signals and general outsiders such as customers or the like are prevented from being involved in a trouble under the occurrence of the crime. Also, the primary door part 2a in the room exit booth 2 is switched so as to be left in the locked state as it is at the time of being opened/closed after being opened/closed and a secondary door part 2b is left in the locked state as it is without being switched to the unlocked state even when the primary door part 2a is opened and turned to the locked state. Thus, the criminal is shut up inside the room exit booth 2 which is the closed area.
