PROBLEM TO BE SOLVED: To provide a Pachinko machine capable of automatically controlling the upward conveyance of Pachinko balls by reducing the size of a Pachinko ball raising device and avoiding jamming of Pachinko balls. SOLUTION: The means for guiding Pachinko balls along the groove inclined and extended upward causes Pachinko balls to roll up under the spiral coil attached along the groove with a part of Pachinko ball riding on the hem wall of the groove. The means is so constructed to have Pachinko ball re-conveyed without jamming at the end of the spiral coil by setting a protrusion, above the hole of the groove guide plate which sends Pachinko balls to the conveyance tube, that pushes Pachinko balls passing over the hole by error back to the inner space side of the spiral coil. Pachinko ball passage sensor is placed in the middle of the means to roll and send Pachinko balls and is structured to acquire the passage information of Pachinko balls and is made possible to control the spiral coil revolution. The Pachinko machine with spiral transfer device of Pachinko balls, thus utilizing the Pachinko balls pay-out information out from the Pachinko game board and the ball passage information, can control the spiral coil revolution and the circulation of Pachinko balls.
