Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a prize ball device that releases prize balls, a prize ball device that detects the entry of safe balls, and a prize ball device that is installed on the back side of a base frame that houses a game board. Various devices such as a safe ball detection device for operating the ball device are built into a mechanism frame independent of the base frame, and this mechanism frame is screwed to the base frame so that it can be opened and closed freely. This invention generally relates to a pachinko machine in which the mechanism frame can be freely opened and closed on the back side of the base frame.

Generally, pachinko machines operate a prize ball device in conjunction with the entry of a safe ball and release the stored prize ball to the player, but at this time the player is notified that the ball has been released. Therefore, a method has been adopted in which a display lamp is provided on the front of the gaming machine and is turned on to notify the player.

In this case, the most common method is to install a switch in the operating part of the prize ball device, operate the switch in conjunction with the ejection operation, and blink the indicator lamp. In the case of a pachinko machine that is built into a mechanism frame that is screwed on and can be opened and closed freely, it is troublesome to wire between the pachinko machine body and this mechanism frame, and in order to simplify the device as much as possible. It is not preferable to place cords or switches near the prize ball device.

In particular, if the mechanism frame is designed to be removably screwed onto the pachinko machine main body, more precisely, to the base frame provided on the machine main body, the mechanism frame will be attached to the pachinko machine main body and the mechanism frame. It is necessary to make it possible to disconnect and connect the cord wired between the two by some method, and it is not possible to easily attach and detach the mechanism frame.

The present invention relates to a pachinko machine in which a prize ball device is incorporated inside a mechanism frame that is screwed to the base frame so that it can be opened and closed freely, and a member that operates in conjunction with the opening operation of the prize ball device, and a corresponding member therefor. The mechanism frame is provided with a switch that is operated by the switch, and a connector terminal that is detachably connected to a connecting piece extending from the switch is provided on the back side of the base frame, so that the mechanism frame is in a closed state. In some cases, the connection piece of the switch is connected to the connector terminal, and when the switch is activated, the electrical circuit of the display device such as an indicator lamp is connected to the connector terminal.
ON and OFF, and when the mechanism frame is opened, separate the connection piece from the connector terminal connector, so that the switch can be freely separated from the connector terminal as the frame opens, and the switch is placed on the mechanism frame side. This is because the electrical wiring of the display device is omitted, resulting in a simple structure, and the wiring does not become an obstacle to the opening/closing of the mechanism frame or the attachment/detachment work.

Hereinafter, the features of the present invention will be described in detail with reference to the illustrated embodiments, and other features will also be explained.

numeral 15 is a prize ball discharging path continued below the prize ball device, and 16 is a ball ejecting gutter attached to the side of the prize ball device.

The prize ball guiding path 13 meanders along the middle of its length, and is connected to the prize ball device 14 immediately after the meandering, and a door 17 is provided at the meandering portion to restrict the inflow of balls from the prize ball device 14.
It is arranged so that it will appear.

The prize ball device 14 has a cylindrical shape, and is attached in a hanging manner by having a mounting piece 18 provided at the upper end supported by a pin 19 implanted in the base plate 10, and the prize ball device 14 is usually attached to the upper end opening. It faces the guide path 13, and the lower end opening faces the prize ball release path 15.

20 closes the opening at the lower end of the prize ball device 14 to store a fixed number of prize balls inside the device, and when a safe ball detection device (to be described later) detects the entry of a safe ball, the prize ball inside the prize ball device is This is a case lid that releases balls, and this lid is attached to a mounting piece 21 provided on the upper part by pivoting a pin 22 implanted in the board 10 so that it can swing freely.
The opening at the lower end of the winning ball device 14 is closed by passing it through a long hole (not shown) provided in the hole and hooking it onto a notch 25 of an interlocking plate 24 provided on the back side.

The interlocking plate 24 is supported so as to be able to swing up and down about a support shaft 26, and the interlocking rod 12 is attached to the swinging end of the interlocking plate 24.
connects. The lower end of a swinging arm 27 that supports the door 17 is connected to this interlocking plate, and when the case lid 20 is opened, the door 17 can be moved from a notch provided in the middle of the length of the guideway 13 to the interior thereof. The prize ball device 14 is inserted into the prize ball device 14 to stop the flow of prize balls flowing down, and when the case lid is closed, retreat from the notch.
A predetermined number of prize balls can be sent to the player. Of course, this operation is caused by the case lid 20 and the swing arm 2 of the door 17.
7 is performed simultaneously by the rocking movement of each associated interlocking plate 24, and this interlocking plate is activated by the vertical movement of the interlocking rod 12 by a safe ball detection device to be described later.

The case lid 20 is opened by the movement of the interlocking plate 24, and the prize balls thus released flow down along the prize ball release path 15 and pass through the release port 29 while striking the bell 28 along the way. The balls are guided to an upper prize ball tray (not shown) on the front of the pachinko machine, and the overflowing balls further flow down through a gutter 30 to a lower prize ball tray (not shown).

Reference numeral 31 denotes a safe ball passage provided on the back side (opened side in Fig. 2) of the board 10 in the lower half of the mechanism frame 6, and reference numeral 32 designates a safe ball passage that sequentially receives consecutively flying safe balls one by one. The controller 33 that allows passage is a safe ball detector that detects safe balls flowing down the safe ball passage 31.

The save ball passage 31 is formed vertically from the left half of the back side of the base frame 1 to the lower part, and the upper end is vertically formed along the mechanism frame 6 and the left edge of the back side of the base frame 1. The controller 32 opens into a ball collecting chamber 35 that is surrounded by a cover 34 that is
1, it is supported so that it can freely swing around a shaft 36 as a fulcrum. The safe ball detector 33 has a shaft 37 implanted in the substrate 10 supported in the middle of its length near the rear end, and the tip thereof faces the arc-shaped part of the safe ball passage 31. Flows from the chamber 35 into the safe bulb passage, and the controller 32 on the way
The tip of this ball receives the safe ball that falls through it and descends.

This detector 33 is connected to the interlocking rod 12 at its rear end, and normally receives this weight and lifts up the tip to wait for the safe ball to enter. Pull down the swinging end of the connecting interlocking plate 24 and insert the case lid 20 into the notch 25.
The prize ball device 14 is closed by latching the pin 23.

In the figure, 38 is a detection plate that detects when there is a shortage of prize balls in the prize ball guiding path 13, 39 is a swing plate,
Reference numeral 40 denotes a connecting rod passed between the rocking plate and the interlocking plate 24, 41 denotes an actuating member that swings in conjunction with the rocking movement of the rocking plate 39, and 42 stands opposite to this actuating member. This is a switch, and 43 is a connector terminal fixed to the back surface of the base frame 1 in correspondence with the switch 42.

The detection plate 38 is provided directly above the prize ball guideway 13 so as to be able to freely swing around a shaft 44, and one piece of the plate 38 is always allowed to fall into the guideway 13 by its own weight, so that the prize balls are filled in the guideway. When the prize ball has a diameter, it is pushed up, the other stopper piece 38a is erected, and it is separated from the pin 45 provided at the free end of the swing plate 39 so that the swing plate can swing freely. There is.

The swing plate 39 is configured to be able to swing up and down at both ends with the shaft 46 as a fulcrum, and the interlocking plate 24 is attached to the rear end side.
A connecting rod 40 is connected to the connecting rod 40 .

The actuating member 41 is supported on a shaft 47 implanted in the base plate so that it can freely swing, and a pin 49 provided on the swing plate 39 is slid into a long hole 48 provided at the rear end so as to be interlocked. The distal end portion 41a thereof faces the movable contact piece 50 of the switch 42.

The switch 42 is connected to the operating member 4 as shown in the figure.
1, and is fixed to the upper free end of the mechanism frame 6 so that the connecting piece 51 protrudes from the free end. Correspondingly, a connector terminal 43 provided on the base frame 1 side has a connecting terminal 52 facing the connecting piece 51, and is joined together when the mechanism frame 6 is closed, and when opened. , it is set to leave.

FIG. 5 is an enlarged perspective view of the switch 42 and the connector terminal 43, and the connecting terminal 52 is connected to the connecting piece 5.
1 and are simultaneously connected when the mechanism frame is closed.

Reference numeral 53 denotes a holder for an indicator lamp attached to the base frame 1 so as to protrude from the front side thereof, and the connector terminal 43 is connected to a circuit connected to a socket of this holder.

In the figure, 54 is a locking device for closing and restraining the mechanism frame 6 in contact with the back surface of the base frame.
By operating the handle 55, a fan-shaped locking plate 56 is hooked onto the free edge of the mechanism frame, thereby allowing the mechanism frame to be restrained.

Now, when the pachinko machine according to the present invention is in use, the mechanism frame 6 hinged to one side edge of the base frame 1 is closed on the back side of the base frame, and the locking device 54 is closed.
The ball supply gutter 4 communicating with the storage tank 3 is thereby connected to the prize ball guiding path 13 of the mechanism frame 6, and the prize balls from the prize ball tank 3 are restrained in this state by being locked. While guiding the ball to the winning ball device 14 and storing a predetermined number of balls therein, the safe ball passage 31 communicates with the ball collection chamber 35, and the safe ball detector 33 facing this is kept in an upright state.

Of course, at this time, the interlocking plate 24 lowers its swinging end by lowering the interlocking rod 12, engages the pin 23 of the case lid 20 in the notch 25, closes the outlet of the prize ball device 14, and releases the prize ball. While storing, pull down the connecting rod 40 to flip up the tip of the swing plate 39, and attach the pin 49 to this.
The actuating member 41 connected via the switch 42 is pressed against the movable contact piece 50 side of the switch 42.

Figures 1 and 3 show this state.
The switch 42 connects the connecting piece 51 to the connecting terminal 52 of the connector terminal 43 by closing the mechanism frame 6. The switch 42 here is set to OFF when the movable contact piece is pressed.
Therefore, under normal conditions, the power supply circuit of the indicator lamp connected to the connector terminal 43 is open and turned off.

When a batted ball fired in such a state enters the safe ball opening of the game board, transfers to the ball collecting chamber 35, and enters the safe ball passage 31, this safe ball passes through the controller 32 and becomes a safe ball. The user rides on the tip of the detector 33 and presses it down with the weight of the ball.

Therefore, as the detector 33 swings, the interlocking rod 1
2 rises and swings the interlocking rod 24 to open the notch 2.
5, the prize ball device 14 is opened, and the stored prize balls are discharged into the prize ball release path 15, and at the same time,
The door 17 is pushed into the guideway 13 to stop the inflow of prize balls, thereby preventing the release of more than a certain number of prize balls.

Simultaneously with the prize ball release operation, the movement of the interlocking plate 24 is transmitted to the swinging plate 39 via the connecting rod 40, and further to the actuating member 41 via the pin 49, so that the tip 41a is connected to the movable contact piece of the switch 42. Since it is moved away from 50, it will be turned ON and the display lamp will turn on.

FIG. 4 shows that as the safe ball detector 33, interlocking rod 12, and interlocking plate 24 operate due to the entry of the safe ball, the interlocking rod 40 rises, and the swinging plate 39 and the operating member 41 move. The movable contact piece 5 of the switch undergoes an oscillating motion.
This shows the state in which the tip 41a of the actuating member separates from 0 and changes to the ON state. When the safe ball passes and the safe ball detector 33 returns to its original state, the switch 42 changes to OFF again, and then the safe state changes. He will have to wait for the ball to fly in.

The present invention is constructed as described above, and includes prize ball devices such as the prize ball guiding path 13, the prize ball device 14, the case lid 20, the prize ball release path 15, and the safe ball path 3.
1. The mechanism frame 6, which incorporates a safe ball detection device such as the safe ball detector 33, or an interlocking rod 12, etc. that connects both devices, together with these mechanical parts, is a swinging device that operates in conjunction with the prize ball operation. It integrally includes a switch 42 that is operated via a plate 39, an operating member 41, etc.
On the other hand, a connector terminal 43 is provided on the side of the base frame 1 to which this mechanism frame is attached, and is connected to the switch 42 so as to be freely connected and detached.Since this connector terminal is connected to the display circuit, the mechanism Frame body 6
By closing the switch, the switch and the connector terminal can be automatically connected to form an electric circuit, and can be separated by opening the frame 6.
The ejection operation of the winning ball device is always transmitted to the switch 42 through means such as the connecting rod 40, the swing plate 39, and the actuating member 41. Therefore, when the mechanism frame is closed and a prize ball is released due to the flying of a safe ball during a game, this can be immediately displayed through a display lamp or the like.

The mechanism frame housing this winning ball device is equipped with only a switch 42 with a connecting piece 51, and since the power cord for the indicator lamp can be omitted, there is no need for wiring space or effort, and at the same time the mechanism If the hinge part of the frame is made detachable, there is no need to connect or disconnect wiring, making it extremely easy to remove.For example, if there is a failure inside the mechanism frame, It is also possible to immediately convert it to a mechanism frame of the same model.

Of course, the method of displaying the release of a winning ball when a safe ball is won is not limited to the lighting of a display lamp, but may also be a buzzer, a bell, etc. In addition to the display lamp, these buzzers, bells, etc. may be used in the connection circuit of the connector terminal. Needless to say, a bell etc. may be incorporated.
