BACKGROUND OF THE INVENTION
The present invention relates to a grand prize opening device used in a pachinko gaming machine.
[0002]
[Prior art]
A large winning opening device of a pachinko gaming machine is also called a variable winning device or an attacker, and is a device that is attached to a game board and greatly facilitates winning of a game ball by a predetermined game signal. For example, a device shown in FIG. 4 has been proposed as this special prize opening device. FIG. 4 is a simplified perspective view showing the mounting board and the special winning opening portion of the special winning opening device, and omitting the rear housing portion.
[0003]
This grand prize opening device has a rectangular prize opening 20 formed in a rectangular shape at the upper center of an arc-shaped mounting board 10 extending to both wings, and an open / close door 30 that opens and closes the grand prize opening 20 is tiltably attached to the front. It is supported on the substrate 10. Decorative plates 11, 12, and 13 are fitted on the front surface of the mounting board 10, on the left and right sides and the lower part of the big prize opening, and cut lenses 14 and 15 for electric decoration are fitted on both wing tips. Is attached by fixing the mounting board 10 to a game board (not shown) with screws (not shown), and also functions as an electrical decoration device for decorating the game board.
[0004]
In the grand prize winning opening 20, there are provided two winning paths 21 and 22 with a built-in game ball sensor which is a non-contact electromagnetic sensor, and a tilting plate 23 which is tilt-controlled is positioned between the two winning paths 21 and 22. Then, the winning path of the winning ball entering the big winning opening 20 is determined with the tilting plate 23 tilted (the winning ball is guided to the winning path 21 in the figure). Usually, one of the winning paths 21 and 22 is set as a specific winning path, and when a winning ball enters the specific winning path, the specific winning state (the big winning opening is again opened) is controlled.
[0005]
The open / close door 30 is integrally molded from plastic, and usually includes a door plate 31 that closes the prize winning opening 20, side plates 32 and 33 provided on both side ends of the door plate 31, and a door plate 31 (back surface). Guide ribs 34 and 35 are formed on the back surface of the door plate 31 so as to be inclined downward so as to guide the game balls that have fallen into the pockets formed by the side plates 32 and 33 into the prize winning opening 20. The gap between the tips of the guide ribs 34 and 35 is located just above the tilting plate 23.
[0006]
In addition, as shown in FIG. 5, pivot shafts 36 and 37 are formed on both sides of the lower end of the opening / closing door 30, and the pivoting shaft 37 tilts (opens) and stands upright (closes). A transmission body 38 that meshes with a driving body such as a solenoid flapper is formed. The open / close door 30 can take an open position and a closed position by the vertical movement of the drive body. Reference numeral 39 denotes a positioning stopper when the opening / closing door 30 is opened.
[0007]
By the way, in such a big prize opening device, as shown in FIG. 5, the game ball B that is falling while the door 30 is being opened is the front upper edge corner E of the door 30, hereinafter this May be sandwiched between the window glass W covering the game board and the opening / closing door 30 may not be opened.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the problem of such a conventional big prize opening device, and provides a big prize opening device that solves an open defect caused by pinching of a game ball.
[0009]
[Means for Solving the Problems]
That is, the present invention closes the big prize opening formed on the mounting board attached to the game board, opens forward by a predetermined signal to form a pocket, and opens and closes the game ball falling in the pocket to the big prize opening in winning opening device having a door, Rutotomoni tilting the edge lines of the door, characterized in that the upper edge of the door were slant in a mountain shape. As a result, even if the falling game ball is sandwiched between the edge line of the opening / closing door and the window glass, it can escape so as to be pushed in the inclination direction of the edge line, and the opening / closing failure of the opening / closing door does not occur. That the front of the door was raised from both ends toward the center, the edge without impairing the well is given and form beauty a simple means either only front upper portion was raised from both ends toward the center of the door The line can be tilted.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments. FIG. 1 is a view showing an open / close door (closed upright) used in an embodiment of the special prize opening device of the present invention, FIG. 1 (a) is a front view, and FIG. 1 (b) is a top view. 2A and 2B are diagrams for explaining the operation of the open / close door of FIG. 1, in which FIG. 2A is a front view, FIG. 2B is a top view, and FIG. 2C is a side view. FIG. 3 is a view showing an open / close door when closed (upright) used in another embodiment of the special prize opening device of the present invention, FIG. 3 (a) is a front view, and FIG. 3 (b) is a top view. .
[0011]
In FIG. 1, the door plate 31A of the open / close door 30A has its front surface raised from both ends toward the center, and has a wall thickness (FIG. 1 (b)) that is symmetrically inclined. Except for the door plate 31A, the other structure of the door 30A is the same as that of the door 30 shown in FIGS. 4 and 5. Therefore, the other parts are denoted by the same reference numerals as those in FIGS. Description is omitted.
[0012]
Thus, since the door plate 31A has a thickness inclined left and right from the center, the edge line EA of the open / close door 30A is also inclined left and right as shown in FIG. 3, and between the edge line EA and the window glass W. Even if the game ball B is pinched, it falls so as to be squeezed in either the left or right direction as shown by the arrows in the figure, and there is no open failure such that the open / close door 30A does not open while the game ball is pinched.
[0013]
In FIG. 1, the entire door plate 31 is inclined. In this case, the shape of the molding die is simplified, but the edge line can be inclined even if the thickness of only the upper end portion of the door plate 31A is changed. The wall thickness was changed symmetrically from the center. In this case, it becomes a symmetrical and balanced and beautiful shape, but in some cases it is not symmetrical from the center, and even if the wall thickness is changed in one direction from one to the other end in one flow good.
[0014]
Further, in order to give the edge line an inclination, it is easy to have an edge line EB in which the upper edge of the door plate 31B is inclined in a mountain shape like the open / close door 30B shown in FIG. Will be understood. Also in this case, it is not always necessary to incline symmetrically as described in the embodiment of FIG. The size and degree of each inclination is an inclination determined experimentally by the size of the door and the coefficient of friction between the game ball and the door.
[0015]
In the above description, the special prize opening device of the present invention has been described based on the special prize opening device shown in FIGS. 4 and 5. However, the present invention is limited to the special prize opening device having such a configuration, structure, and shape. Needless to say, the present invention can be applied to all large winning opening devices having an open / close door (opening and closing and upright closing operation) for opening and closing the large winning opening.
[0016]
【The invention's effect】
The present invention closes a grand prize opening formed on a mounting board attached to a game board, opens forward by a predetermined signal to form a pocket, and an open / close door that guides a game ball falling in the pocket to the big prize opening In the grand prize opening device, the edge line of the opening / closing door is inclined. As a result, even if the falling game ball is sandwiched between the edge line of the opening / closing door and the window glass, it can escape so as to be pushed in the inclination direction of the edge line, and the opening / closing failure of the opening / closing door does not occur.
