PURPOSE:To eliminate an evil, generated by a clerk in charge carrying a key freely opening a door, by constituting a device so as to enable the front door to be automatically opened and closed by utilizing a transmission mechanism, operating a machine being associated with a command room, and a remote control switch device. CONSTITUTION:By turning on a lamp D by a button C from an in-shop clerk in charge, a corresponding number, agreeing with a machine B, set up in a command room A is simultaneously turned on. A connecting button is pressed in the command room A, and a door of the machine B is opened by a publicly known remote control system. When the clerk in charge closes the door finishing a suitable process, lamps in both the command room and the machine are simultaneously turned off, and the machine B is reset to a condition able to play a game. By the method thus obtained, an unfair practice can be prevented such that the clerk in charge in the shop delivers balls secretly communicating with a customer freely opening the door by a key stock in hand.
