PROBLEM TO BE SOLVED: To reduce damages even in the case that an operation of matching timing of drawing by a drawing part with a winning random number zone is intentionally performed. SOLUTION: A main control board 40 is housed in a board housing case 41 and the board housing case 41 is disposed on a back surface inside an upper housing part 11b. The main control board 40 is provided with a CPU 40a, a ROM 40b, a random number generator 40c, an electronic drawing part 40d, a winning role decision part 40e, a RAM 40f and a discrimination part 40g. The electronic drawing part 40d draws one random number from the random number generator 40c. The discrimination part 40g compares the drawn random number LR with stored random numbers MR1-MR10. In the case of discriminating that the drawn random number LR is a numerical value in the range of±10 from the stored random numbers MR1-MR10 for five times out of ten times of drawing in the electronic drawing part 40d, the CPU 40a drives a camera 20, photographs the face of a player and issues alarm sound from a loudspeaker 38.
