Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine equipped with an opening/closing panel fitted with a ball supply tray for storing balls used in games.

0002

[Prior Art] Conventional pachinko machines, for example,
As described in Publication No. 160781, one side of a metal plate opening/closing panel is pivotally attached to a metal frame attached to the open edge of the front frame so as to be freely openable and closable, and a ball supply tray is attached to the front of this opening/closing panel. It is installed.

0003

[Problems to be Solved by the Invention] However, the opening/closing panels in conventional pachinko machines are made of metal plates, so they lack decorative properties. I was only able to process it to a certain extent. Furthermore, if the opening/closing panel is made of plastic to make it easier to decorate, the rigidity will be insufficient, and there is a risk that fraud may be committed by melting the opening/closing panel itself with hot piano wire, making a hole, and inserting the piano wire through the hole. Due to this, it cannot be put to practical use.

0004

[Means for Solving the Problems] The present invention has been proposed in view of the above, and has one side pivotally attached to the front frame side so as to be openable and closable.
In a pachinko machine equipped with an opening/closing panel with a ball supply tray arranged on the front side, the opening/closing panel has an outflow opening for passage of prize balls on the base end of the shaft, and a hole from the ball supply tray on the free end side. A substrate made of a metal plate having an inlet opening through which the fallen balls pass in a line, and a plastic plate-shaped body having a surface portion smaller than the surface portion of the substrate; An outflow port is provided at a corresponding position, and a guide gutter that can be fitted backwards is provided from the opening edge of the outflow port, and a design board is overlapped with an inflow port provided at a position corresponding to the inflow opening. They are fixed together so that the storage part faces the outflow port of the design board, and the lower end of the guiding part that causes the balls in the storage part to align and flow down in a line faces the inflow port. This device is characterized by a ball supply tray attached to the front of the design board.

[0005]

[Operation] Since the metal plate substrate is overlapped with the plastic design plate to form the opening/closing panel, the rigidity of the substrate complements the rigidity of the design plate, increasing the rigidity of the opening/closing panel as a whole.

[0006]

[Example] As shown in FIG. 1, a pachinko machine 1 has a machine frame 2.
A frame-shaped front frame 3 is hinged to the front frame 3 so that it can be opened and closed, a glass frame 4 and an opening/closing panel 5 are pivoted to the opening of the front frame 3 so that they can be opened and closed independently, and balls are supplied to the front of the opening/closing panel 5. A plate 6 is attached.

The opening/closing panel 5 consists of a substrate 7 made of a metal plate and a design plate 8 made of plastic. The substrate 7 is formed by forming a thin metal plate into a horizontally long rectangle, and has bent portions 9 formed toward the rear at the upper edge, lower edge, and right edge, and is wound toward the rear at the right edge. A shaft support portion 10 is formed, and the shaft 11 is fixed by the support portion 10, and a downward U-shaped blocking portion 12 is further formed in the bent portion 9 of the upper end edge to prevent the entry of piano wires, etc. . Further, a horizontally rectangular outflow opening 14 is provided at the base end of the surface portion 13, that is, at the upper left side in FIG. A rectangular switch opening 16 is provided, and inlet openings 17 large enough to allow balls to pass in a line are provided on the free end side, that is, on the right side, and on the left, right and center near the top edge, and near the bottom edge. Fixing holes 18 are opened on the left, right, and center sides, respectively.

[0008] The design plate 8 is a thin plastic plate shaped like an oblong rectangle that is the same size as the surface portion 13 of the substrate 7 or slightly smaller, and has edges 19 facing rearward on the four circumferences. The portions where each edge 19 and the surface portion 20 intersect, and the portions where the edges 19 and 19 intersect are formed of curved surfaces. In the surface portion 20, an oblong rectangular outlet 21 is provided at a position corresponding to the outlet opening 14 of the substrate 7, and a guide trough 22 having a substantially rectangular cross section is arranged rearward from the opening edge of the outlet 21 with a design plate. A small sound effect outlet 23 is provided below the outlet 21 at a position corresponding to the speaker opening 15, and a switch is provided at a position corresponding to the switch opening 16. A switch operation member holder 25 protruding forward to hold the operation member 24 is attached to the design plate 8.
An inlet 26 is formed at a position corresponding to the inlet opening 17, and a guide opening 27 whose lower opening edge is slightly inclined is formed in series with the inlet 26.

The guiding opening 27 is positioned and tilted so as to follow the bottom surface of a storage section 28 to a guiding section 29 of the ball supply tray 6, which will be described later, and its length in the vertical direction is equal to the diameter of the ball. It is set larger than . In addition, the surface portion 20 of the design board 8 may be provided with appropriate colors or patterns to enhance the decorative effect, or an emblem 30 may be attached to the surface portion 20 to enhance the decorative effect. A relief pattern may be applied to the surface.

Further, on the back surface of the design board 8, as shown in FIG. 4, a fastener 32 having a plurality of bent legs 31 is provided at a position corresponding to the fastening hole 18 of the substrate 7. therefore,
In order to attach the design board 8 to the surface portion 13 of the board 7, each fastening tool 32 of the design board 8 is inserted into the fastening hole 18 of the board 7 from the front, and the bent legs 31 are fastened by bending them. be able to. Note that the switch operating member 24 is fitted into the switch operating member holder 25 so that the operator of the switch body 33 attached to the board 7 is operated by the forward and backward movement of the switch operating member 24 after the switch operating member holder 25 is fixed.

As shown in FIG. 5, the ball supply tray 6 has a storage section 28 with an open rear side and a relatively wide front and rear width, and a storage section 28 with a gradually narrowed flow path on the right side of the storage section 28. Guidance guide part 2 that guides the balls flowing down from the ground while aligning them in a line.
9, and a first plate decoration member 35, a second plate decoration member 36, a third plate decoration member 37, etc. attached to the front and lower part of the plate body 34. A rail 38 made of a thin metal plate with a U-shaped cross section is fitted to the end edge to cover a portion of the bottom of the guide portion 29 and the bottom of the storage portion 28 so as to be flush with the bottom of the other portion. . The rail 38 is fixed in such a manner that its rear edge protrudes rearward from the rear edges of the storage section 28 and the guiding section 29 by approximately the thickness of the design plate 8. Furthermore, a driving operation mechanism 40 for the shutter 39 for extracting the balls from the storage portion 28 is incorporated in the first plate decoration member 35 described above.

In order to attach the ball supply tray 6 having the above-described structure to the opening/closing panel 5, the rear end edge of the rail 38 is inserted into the guide opening 27 of the design plate 8 and comes into contact with the surface portion 13 of the base plate 7. The rear end of the ball supply tray 6 is connected to the surface portion 2 of the design plate 8.
0, and in this state, the tip of a screw inserted from the back side of the board 7 is screwed into the screw hole of the ball supply tray 6, thereby assembling the base plate 7, the design board 8, and the ball supply tray 6 as a trinity. When the ball supply tray 6 is attached to the front surface of the opening/closing panel 5 in this manner, the inclined lower end of the guiding portion 29 is located at the inlet 26 of the design plate 8, and the outlet 26 of the design plate 8 is located at the inlet 26 of the design plate 8.
A storage section 28 is located in front of 1.

Further, as shown in FIG. 3, on the back side of the opening/closing panel 5, a speaker 41, a switch 33, etc. are attached, and a plastic case 42 is attached. Inside this case 42, as shown in FIG. 6, there is a ball introduction channel 44 whose upper end inlet communicates with the inflow opening 17 of the base plate 7, and whose lower end communicates with a ball supply port 43 that opens facing the firing rail. A shutter 39 is provided in the middle of this ball introduction channel 44, a ball supply member 45 is swingably pivoted in front of the ball supply port 44, and a permanent magnet provided on the ball supply member 45 is provided. An electromagnet 47 is attached facing the ball supply tray 46, and the drive operation mechanism 40 for the ball supply tray 6 described above is connected to the shutter 39.

When the shaft 11 of the opening/closing panel 5 is inserted into the bearing on the front frame 3 side and the opening/closing panel 5 is closed, the guide trough 22 that passes through the outflow opening 14 of the base plate 7 and protrudes to the rear of the opening/closing panel 5 opens into a pachinko machine. It is connected to a prize ball discharge gutter (not shown) on the main body side of the machine 1, and a ball supply port 43 is located above the firing rail.

Therefore, when the player throws balls into the ball supply tray 6 in this state, these balls flow down while being aligned in a line by the guide guide section 29, and the balls that flow down the guide guide section 29 are placed on the design board. The ball passes through the inlet 26 of the ball 8 and the inflow opening 17 of the base plate 7 and flows down the ball introduction channel 44 in the case 42, and the first ball hits the ball supply member 45 and stops. Note that when the player throws a ball into the storage section 28, the ball located in the front of the opening/closing panel 5 is supported with the lower end of the spherical surface in contact with the metal rail 38, and the side end of the spherical opening/closing panel 5 Since the part enters the guide opening 27 of the design plate 8 and contacts the surface of the metal plate base plate 7, the rolling resistance is smaller than when it rolls in contact with plastic. Therefore, the ball can flow down smoothly with little rolling resistance. Therefore, even if the bottom surface has a slight downward slope, the ball will hardly stop in the storage section 28 or the guiding section 29. In addition, in the surface portion 20 of the design plate 8, the portion that is likely to come into contact with the metal ball is opened as the guiding opening 27, so that the surface of the plastic design board 8 may become rough due to contact with the metal ball. , it hardly gets dirty.

When the player operates the firing operation handle 48, the firing device is activated and the firing rod rotates back and forth, and the electromagnet 47 repeats energization and demagnetization in synchronization with the rotation of the firing rod. When the electromagnet 47 repeats excitation and demagnetization, the ball supply member 45 swings around the shaft 49, so that the balls in the ball introduction channel 44 are sent one by one from the ball supply port to the launch rail. is supplied to the firing position. The ball supplied to the firing position is fired into the game section on the surface of the game board by rotation of the firing rod. When the ball fired into the gaming section wins, the prize ball discharge device is activated and a predetermined number of prize balls flow down the prize ball discharge gutter, and these prize balls are discharged from the guide gutter 22 into the storage section 28. . Further, when the player performs an external operation such as operating the operating member 24 of a switch provided on the opening/closing panel 5, predetermined technical intervention is possible, such as stopping the variable display of the variable display device.

Furthermore, when the game is over and the balls in the ball supply tray 6 are exchanged for prizes or moved to another pachinko machine 1, the ball removal operation section of the ball supply tray 6 is operated. As a result, when the shutter 39 is moved, the balls in the ball supply tray 6 and the guide portion 29 are discharged into the lower tray 50 through the ball discharge flow path.

Note that the opening/closing panel 5 in the present invention includes the following:
In addition to the speaker 41 and the external operation switch 33 described above, other members related to the game can be assembled. For example, as shown in FIG. 7, a card insertion slot 51 is formed in the surface portion 20 of the design board 8, and a card insertion guide part 52 having an inclined surface is integrally formed around the card insertion slot 51, and the board 7 Alternatively, an opening 53 may be formed at a position corresponding to the card insertion slot 51, and a card reader/writer 54 may be attached to the back surface of the board 7.

[0019]

[Effects of the Invention] As explained above, the present invention constitutes an opening/closing panel by overlapping a metal plate substrate on the back side of a plastic design plate. Decorations that were previously impossible are now possible. Therefore, compared to conventional pachinko machines, the decorative effect can be greatly enhanced. In addition, in the opening/closing panel according to the present invention, even though the design board facing the player is made of plastic and easily melted by heat, the back side is provided with a metal board, so the design can be created by the player using a heated piano wire or the like. Even if a hole is made in the board, the board can prevent piano wire, etc., from penetrating the board. Therefore, it is possible to deal with fraudulent acts using a piano wire or the like. Furthermore, since the metal plate substrate also functions as a reinforcing material, the rigidity of the opening/closing panel as a whole can be increased.
