[Detailed Description of the Invention] "Industrial Application Field" The present invention is designed to minimize the number of replacement parts on the pachinko machine main body side when replacing only various game boards due to changes in game content. This invention relates to a winning ball collection structure for a pachinko machine that can be used for a long period of time and allows winnings to be processed smoothly even when a game board is replaced.

``Prior Art'' Recently, pachinko machines, as is well known, are used to play games such as when a ball hits a particular winning chutzker on the game board, or when an electronic roulette is activated and the numbers displayed on the display are set in a predetermined combination. The game machine is equipped with a number of electronic control circuits that operate the electric prize winning device continuously for a certain period of time to provide a profit to the player when the game enters a state. Furthermore, among the display devices and electric winning devices for the electronic roulette and the like mentioned above, there are many devices that protrude significantly to the rear of the game board and are fixed to the game board. For machines equipped with electronic control circuits as described above, display devices protruding from the rear of the game board, and electric winning devices, in many cases, only the game board containing those devices needs to be replaced, and the pachinko machine The main body of the machine is on the market in a form that can be used for a long period of time, following on from what was previously used. There is also a form of replacing a game board that does not include an electronic circuit, a display device, or a variable prize winning device.

``Problems to be Solved by the Invention'' In this way, even if only the game board was replaced, there were various structures on the back of the game board. Pachinko machines were used by forming recesses or drilling openings to fit each game board. However, such machining must be done at the same game parlor where the pachinko machine itself is installed, which is not only very time-consuming, but also requires the machine board to be replaced once again with another game board. Sometimes, it would no longer match the game board, and the mechanism board would eventually have to be replaced, which was an inconvenience.

The present invention was made to eliminate the above-mentioned disadvantages, and its purpose is to eliminate the need for special processing on the pachinko machine body when replacing game boards with various back structures. To provide a winning ball collection structure for a pachinko machine that can be used with various game boards for a long period of time, and allows winning balls to be processed smoothly even when the game board is replaced.

"Means for Solving the Problems" In order to achieve the above object, the present invention includes a machine frame, a front frame attached to one front side of the machine frame so as to be openable and closable, and a front frame attached to the back side of the front frame. A game board is detachably installed, and a series of back parts such as a prize ball ejection mechanism are provided on the back side of the game board, which is attached to one side of the back of the front frame so as to be openable and closable so as to cover the back of the game board. In a pachinko machine including a mechanism board, a plurality of winning devices provided on the game board are attached to the back surface of the game board so as to cover the main areas of the back surface and maintain a constant distance from the back surface of the game board. A winning ball collecting cover is provided, and the mechanism plate has an opening window formed on a surface corresponding to the winning winning ball collecting cover, and the opening window is a box in which a board incorporating an electronic control circuit is housed. is fixed to the outer surface of the entered prize ball collecting cover, and a rear protruding part in the case where the rear protruding part of the electric winning device provided on the game board protrudes from the entered prize ball collecting cover. This system adopts the winning ball assembly structure of a pachinko machine, which is characterized by the shape of the ball.

"Function" According to the present invention, the game board is provided with a winning ball collection cover that covers the main area on the back side of the game board, and the mechanism plate on the side of the pachinko machine body is provided with a winning ball collection cover that corresponds to the winning ball collection cover. In the case where a box containing a board with an electronic control circuit incorporated therein is fixed to the outer surface of the winning ball collection cover, the box and the rear protrusion of the electric winning device provided on the game board are connected to the winning ball collection. By providing an opening window large enough to pass through the rear protrusion when it protrudes from the cover, a newly replaced game board has a base box and the back structure of the game board protrudes. However, the box and the rear protrusion can be pulled out to the rear through the opening window provided on the mechanism plate, making it possible to replace the game board without any modification to the mechanism plate. . Moreover, regardless of the structure of the back surface of the game board, since the winning ball collection cover substantially closes the opening window of the mechanism board, winning balls do not leak out and smooth processing of winning balls is performed. Furthermore,
When the rear protrusion of the electric winning device provided on the game board protrudes from the winning ball collecting cover, by providing the winning ball collecting cover with a winning device cover that covers the rear protruding part, the game board can be used alone in the gaming hall. There is no chance of damage caused by hitting the rear protrusion of the electric winning device during transportation.
