PROBLEM TO BE SOLVED: To provide an attendant calling device and system which can call parlor attendants quickly. SOLUTION: A control part of an inland managing device 40 refers to an ID number list data and makes a short range wireless communication part transmit an attendant call signal for calling an attendant's portable terminal 80 capable of handling jamming of coins at any inter-machine device 20. The transmission power of the short range wireless communication part is variable within the range of 0.5 to 100 mW for instance and, for example, the attendant call signal is transmitted at a power of about 1 mW for 10 sec after the reception of an error generation signal from a coin jamming sensor 60 by the island managing device 40. Thus, the portable terminal 80A of an attendant working within an area of about 10 m in radium centering around the island managing device 40 is called up from among the attendants' portable terminals 80 capable of handling coin jamming at the inter-machine devices 20.
