DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a game board provided with various game devices such as a variable winning device and a variable display device, and game nails, a hitting ball launching device and a prize ball discharging device. The present invention relates to a pachinko machine equipped with a game board mounting mechanism for making it possible to replace a front frame provided with various game function device groups such as devices.

<Prior art> The pachinko machine installed in the game store does not have to replace the entire pachinko machine each time the game content is changed, but only the game board that can play various game contents can be replaced. It has become. In other words, for the front frame that is fixedly equipped with various game function device groups necessary for realizing a pachinko game such as a ball launching device and a prize ball ejecting device, various game devices according to specific game contents are provided. By installing the provided game board, it is possible to change to a different game machine. The front frame is installed in the game shop in a state of being openably and closably stored in the machine frame.

By doing this, every time a pachinko parlor exchanges the model, the entire pachinko machine including the machine frame and the front frame is replaced, and a large amount of expense is not compelled, compared to the replacement of the large and heavy pachinko machine body. Replacing the game board is also a great merit for the game store in that the work can be efficiently performed with relatively little labor.

And, as one of the game board mounting mechanisms included in the above-mentioned pachinko machine capable of exchanging game boards, a game board storage frame is provided on the back side of the front frame that is hinged to the machine frame, and the front frame is provided. With the game board inserted into the game board storage frame from the window of the game board, by operating the locking levers provided on both the left and right sides of the game board storage frame, the locking pieces of the required shape can be placed on both the left and right sides of the game board. It is known that the game board is locked in a predetermined part of the game board so that the game board can be mounted in the game board storage space.

<Problems to be Solved by the Invention> However, in a pachinko machine equipped with the above-mentioned conventional game board mounting mechanism, the work of inserting the game board into the game board storage space and the operation of operating the locking lever are performed. There were also points that could not be said to be easy and efficient.

That is, in the conventional pachinko machine, there is nothing that supports the game board placed on the game board mounting portion of the game board storage frame so as not to tilt until the game board is fixed by operating the locking lever. Since there is no such thing, the work of positioning the game board at a predetermined position in the game board storage space is complicated so that the game board can be locked by the locking pieces provided on both left and right sides, and the locking lever is operated. Until the game board is locked by the operator, the operator must manually support the game board in the predetermined position of the game board storage frame.

Therefore, in the work of mounting a recent game board having a plurality of relatively large and heavy game devices on the game board storage frame, a considerable amount of labor is required, and such a heavy game board is used.

In addition to not being able to spend sufficient time for adjusting the nails, if there are bent nails during the game board replacement work, the nail adjustment work will take more time.

Moreover, this work is performed on the front frame that is hinged to one side of the machine frame, and unless the front frame is opened from the machine frame, it is provided on both left and right sides of the game board storage frame. The stop lever cannot be operated. That is, although the locking lever located on the open side (anti-hinge side) of the front frame can be operated relatively easily, the locking lever located on the hinge side of the front frame moves the front frame to the machine frame. It cannot be operated unless it is wide open.

Thus, in order to operate the locking lever on the hinge side, the operator has to open the front frame largely while holding the game board in a predetermined state with respect to the open front frame. The work of mounting the game board becomes very complicated, and the work efficiency is significantly reduced.

In addition, if the gaming board needs to be attached or removed in order to repair a pachinko machine that has malfunctioned during the business hours of the pachinko parlor, in order to attach or remove the gaming board, the front frame Therefore, the player who is playing a game with another pachinko machine adjacent to the pachinko machine concerned is annoyed because it must be opened to a large extent.

Therefore, the present invention can easily perform the work of inserting the game board into a predetermined position in the game board storage space of the game board storage frame and the work of fixing the inserted game board to the game board storage frame. An object of the present invention is to provide a pachinko machine capable of effectively preventing a game nail from being accidentally bent during a game board replacement operation.
