This invention relates to a winning ball collection structure for a pachinko machine that can be used over a long period of time and allows winning balls to be processed smoothly even when a game board is replaced.

``Prior Art'' Recently, as is well known, pachinko machines are used to play games such as when a ball hits a particular winning chuck on the game board, or when an electronic roulette is operated and the numbers displayed on the display are set in a predetermined combination. Various electronic control circuits are provided, such as operating the electric prize winning device continuously for a certain period of time to give a profit to the player when the winning state is reached. Furthermore, among the display devices and electric winning devices of the above-mentioned electronic roulette and the like, 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 continues to be on the market in a form that continues to be used for a long time. 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.

``The problem that the invention seeks to solve'' In this way, even if only the game board is replaced,
Since there are various structures on the back of the game board, conventionally, the mechanical plate covering the back of the game board has been processed by forming recesses or openings to fit each game board. The pachinko machine itself was used after being subjected to However, such machining must be done at the game parlor where the pachinko machine itself is installed, which is not only extremely time-consuming, but once the machine board has been machined, it cannot be used again when it is replaced with another game board. This caused the inconvenience that it no longer matched the game board, and the mechanism board eventually had to be replaced.

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 handle various game boards for a long time even when the game board is replaced, 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-mentioned objects, the present invention has 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, the 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 the rear protruding part when the rear protruding part of the electric winning device provided on the gaming 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 being formed into a rectangular size.

"Function" The present invention provides a game board with a winning ball collection cover that covers the main area on the back side of the game board, and a mechanism plate on the side of the pachinko machine main body that has a surface corresponding to the winning ball collection cover. In the case where a box containing a board incorporated in an electronic control circuit is fixed to the outer surface of the winning ball collecting cover, the box and the rear protrusion of the electric winning device provided on the game board are attached to the winning ball collecting cover. Since the rear protruding part and the opening window part of approximately rectangular size are provided, the newly replaced game board has a base box and the back surface structure of the game board protrudes. Even with such a structure, the box and rear protruding part are designed to come out rearward through the opening window provided on the mechanism plate regardless of the amount and range of protrusion, and the box and rear protrusion can be removed without any processing on the mechanism plate. It is possible to replace the game board. 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 protruding part 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, it is possible to play the game board alone. This prevents damage caused by hitting the rear protrusion of the electric winning device when transporting it to the venue.

"Embodiments" The present invention will be described below based on embodiments shown in the drawings.
