<Prior art> As is well known, a wide prize-ball collecting gutter is attached to the back side of the game board in a state of covering the prize-ball discharging ports of all prize-winning tools, and the prize-winning ball collecting gutter ejects each prize-winning tool. The winning balls are collected, and the collected winning balls are controlled to flow down to one by the winning ball flow-down control device to ensure the operation of the winning ball discharging device. Since such a winning ball gathering gutter will protrude from the back surface of the game board, an opening is formed in the back mechanism board equipped with a ball lead-out gutter, a ball flow-down device, etc., and a prize ball discharging gutter is provided in the opening. Designed to fit.

In addition, recent game boards are provided with a central winning device, which is a large-scale winning device such as a so-called attacker that can win a large number of hit balls in a short time in order to enhance the enjoyment of the game, and the number of prize balls discharged is changed for each winning opening. In order to enhance the fun of the game, a prize ball detector for determining the type of prize hole in which the prize ball is won is provided in a predetermined prize hole, or the player is informed of the current game state by a light emission display. The mainstream is to provide a large number of electric decoration devices for enhancing the decorative effect of the game board.

The above-described central winning device, winning ball detector, electrical decoration device, etc. are connected to an electrical control device that comprehensively controls the operation of the pachinko machine via a wiring cord, and various information is supplied to the electrical control device. In addition, it operates based on a command signal or the like from an electric control device.

<Problems to be solved by the invention> However, as described above, on the back side of the game board provided with the central winning device, the winning ball detector, the electric decoration device, etc., winning balls derived from various winning holes are provided. Since the winning ball collecting gutters for collecting in an aligned manner are arranged, various obstacles occur. That is, since the rear part of the central winning device is projected from the winning ball collecting gutter, it is necessary to open the window part so that the rear part of the central winning device does not collide, and a means for pulling out many wiring cords. Must be taken.

Therefore, when a through hole for penetrating various cords is opened in the winning ball collecting trough made of synthetic resin, the physical strength of the winning ball collecting trough is reduced. Moreover, since there are a large number of cords that connect the central winning device that performs a relatively complicated operation and the electrical control device, it is necessary to individually open through holes for penetrating the cords drawn from these central winning devices. Then, the strength in the vicinity of the central winning device is significantly reduced. In addition, the handling of the wiring in each wiring through hole becomes complicated, which leads to a reduction in the efficiency of the game board manufacturing work and maintenance inspection work.

It is also possible to make the window part through which the rear part of the central prize device penetrate a little so that all the wiring drawn from the central prize device can be passed, but if this through window part is too large, the prize ball A prize ball spills out of the gathering gutter, which disadvantages the player, or an employee and a player collude with each other to allow a dishonest act of putting a ball into the prize collecting gutter. Also, even if there is a gap between the winning ball collecting gutter and the opening of the back mechanism board, the overflow ball from the ball storage tank provided in the back mechanism board may enter the winning ball collecting trough. , Balls will be intentionally put into the winning ball gathering gutter, and it will be impossible to discharge the winning balls only with proper winning balls.

Therefore, the present invention is a pachinko machine that can prevent the strength of the winning ball gathering gutter from significantly lowering, improve the work efficiency at the time of manufacturing the game board and at the time of maintenance and inspection, and can expect the prize balls to be discharged by the appropriate winning balls. For the purpose of providing.
