Filed: 2020-03-02
Abstract: To provide a metal-made chute which is enhanced in the transport efficiency and versatility of a product or a scrap in press working.SOLUTION: A metal plate being flat plate is bent, and formed into an M-shape in a cross section view. Legs are formed at both end parts in a width direction by bending the metal plate, a height of a center portion in the width direction is set low, and heights of both the end parts in the width direction are set high when the metal plate is installed at a press machine.

Filed: 2020-03-03
Abstract: To provide a game machine capable of optimally entering a game ball to a specific area that produces a game state advantageous to a player.SOLUTION: When a jackpot lottery is won, the game machine produces a special game state formed by combining a plurality of rounds (16 rounds) and, when a game ball enters a specific passage TA in a specific round (a sixth round) in the special game state, produces a probability variable game state. In a round immediately before the specific round, flow-down of game balls on a route leading to the specific passage TA is controlled by operation of an upper large winning device, and rejection of game ball entry in the specific passage TA is controlled by a difference in an interval time of 0.5 second or 3.0 seconds immediately before the subsequent specific round. Therefore, control patterns of a plurality of types of special game states can be commonalized excluding the interval time so as to easily simplify the control and easily differentiate entry probabilities of game balls to the specific passage TA.SELECTED DRAWING: Figure 33
