Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an effective arrangement of components and components of a mechanism section for controlling the processing of safe balls and out balls, the release of prize balls, etc. of a pachinko machine.

As is well known, in a pachinko machine, the game progresses depending on whether the ball hit on the game board flies into the winning hole or not.
When the ball enters the winning hole, a predetermined number of separately stored prize balls are released to the player and the game can be continued based on this, but the operations after firing these balls are controlled by the game board. The processing is carried out in a so-called mechanism section installed behind the machine.

The main devices in this mechanism can be roughly divided into devices that process winning balls, that is, safe balls, and devices that control prize balls that release prize balls to the player in response to the processing of safe balls. can.

Conventionally, these devices have been unevenly arranged so as to overlap within a limited area on the back side of the base frame board housing the game board, and have been assembled into an extremely complicated structure.

For this reason, the assembly of devices and parts becomes complicated, and not only is manufacturing efficiency low, but also troublesome repairs and maintenance inspections are required, which is extremely inconvenient.

Furthermore, since there was no uniformity in the arrangement of the parts, communication between the parts was poor, which could cause malfunctions or impede the flow of the ball.

The present invention has been researched and developed in view of the above-mentioned circumstances, and includes devices related to detection and control of safe balls,
The parts, the device for controlling the release of the prize ball, and the parts are systematically divided into two parts, and one part is placed on the vertical planar first layer provided along the back of the base frame board, and the other part is placed on the first layer in the form of a vertical plane provided along the back surface of the base frame board. Equipment parts are arranged on a second layer formed behind this first layer to improve communication between the equipment and parts, simplifying the process, and simplifying the molding and assembly of each part, as well as facilitating maintenance and inspection. It is an object of the present invention to provide a pachinko machine that facilitates the operation of the machine and also greatly reduces the risk of failure.

Examples illustrating the present invention will be described below.
Its features will be explained in detail.

Figure 1 is a front view of the mechanism of the pachinko machine, Figure 2 is a front view with a part of the mechanism cut out, and Figure 3 is a view of the mechanism with the mechanism frame that constitutes the mechanism opened. It is a front view. Reference numeral 1 shown in the drawing is a base frame plate formed of a shallow box-shaped metal plate that is fixed to a door frame 2' that is screwed onto the front surface of the machine frame 2 of the pachinko machine, and 3 is a base frame plate formed from a metal plate. A window is opened approximately in the center, 4 is a prize ball storage tank attached to the upper left side of the base frame plate avoiding this window, and 5 is a prize ball guide gutter connected to the bottom of this storage tank, and this guide gutter 5 and the storage tank 4 are fixedly attached to the back surface of the base frame plate.

The surface of the prize ball guiding gutter 5 is covered with a cover 6,
A rectangular cylindrical case 7 extends downward from the lower surface of the left end of the cover 6. The case 7 has a built-in stop device 8 that closes the supply port for supplying pachinko balls to the firing position of the ball firing device to stop the automatic supply of fired balls when there is a shortage of stored balls. The cover 6 and the case 7 enclose the upper left edge, the left edge, and the left half of the lower edge of the window 3 formed in the base frame board.

9 includes parts of a safe ball detection system including a safe ball detector that detects safe balls that fly in through the winning device provided on the game board 10, and a system that detects winning balls in response to safe balls detected by the safe ball detector. It is a mechanism frame that integrally incorporates various parts of the prize ball system, including the prize ball case that releases them, and interlocking members that connect the two systems.

The main body of the mechanism frame 9 is made of a plastic material, and its overall shape is approximately L-shaped as shown in the figure. As shown in FIG. 4, this frame has a chamber 12 with one side open, which accommodates interlocking members and parts of the safe ball detection control system on the back side (the side facing the base frame plate 1) with the board 11 at the center.
On the other side, there is a room 13 for storing parts of a processing control system for winning balls and out balls.

In order to clarify the chamber 13 of the mechanism frame 9 that houses the prize ball system, FIG.
15 is a prize ball case installed following the meandering portion 16 of this guideway 14, and 17 is a prize ball case provided continuously below the prize ball case. A ball extraction passage 18 is provided parallel to the discharge passage.

The prize ball case 15 is formed into a cylindrical shape, and the upper end of a piece 19 extending from the side is connected to the base plate 11 with a pin 20.
The lower end is swingably mounted by pivoting at the lower end, and the opening at the lower end is always exposed to the prize ball discharge path 17 by means of a stopper (not shown).

21 closes the lower end opening of the prize ball case 15 to prevent the release of the stored prize balls, and opens when a safe ball detector described later is activated to release the stored prize balls into the prize ball release path 17. In the case lid, 22 is a control piece for regulating the inflow of balls to prevent subsequent balls from flowing into the prize ball case when the case lid 21 is in an open state, and 23 is a control piece for regulating the inflow of balls into the prize ball case when the case lid 21 is in an open state.
2 is an actuating member pivotably mounted on the back side, that is, on the room 12 side, so that the actuating member always operates in a fixed relationship.

The prize ball device in this embodiment is composed of the prize ball case 15, case lid 21, control piece 22, a part of the guideway 14, and the operating member 23, and passes from the storage tank 4 to the prize ball guiding trough 5 into the guideway. The prize balls guided to the prize ball case 14 enter the prize ball case 15 and are stopped at the position of the lid 21 which closes the lower end opening, and the case is filled. At this time, the control piece 22 is retracted from the guideway 14 and is in an open state, allowing the subsequent ball to flow in.

The prize ball release path 17 is equipped with a bell 24 at its lower end, and its opening faces a communication window 25 provided in the base plate 11, and continues to an overflow ball path 26. The ball extraction passages 18 arranged in parallel with each other are formed as independent passages so as to reach the lower end of the frame.

On the other hand, in FIG. 3, the mechanism frame 9 is opened and the board 11 is opened.
The back side, that is, the room 12 side, is opened, and 2
7 is a safe ball passage, 28 is a controller that allows consecutively flying safe balls to pass through one by one, 29 is a safe ball detector that detects safe balls flowing down the safe ball passage 27, and 30 is a safe ball detector. This is a connecting rod that is an interlocking member that transmits the operation of the ball detector to the operating member 23 of the prize ball device.

The safe ball passage 27 is opened and communicated with a sloped ball gathering frame 31 formed by the lower upper edge 7' of the case 7 and the lower upper edge 9' of the mechanism frame, and the controller 28 is connected to the safe ball passage 27. It is installed facing the upper part of the passageway.

The controller 28 is equipped with a weight at the rear end (right side in FIG. 2), and always urges the front end upward with the pivot 32 as a fulcrum, waits for the safe ball to flow in, and places the safe ball in the concave receiving portion 33. When the ball enters the ball, the ball receives its weight, converts into a forward-leaning position, and sends it out into the path formed in a loose arc shape, and at this time, the safe ball that flies in consecutively is blocked by the stopper part 34, and the two balls are simultaneously This prevents it from flowing into the above passage.

The safe sphere detector 29 has a shaft 3 implanted in the substrate 11.
5 has a shaft bearing near its rear end so that its tip faces the safe ball passage formed in the arc shape,
When a safe ball flows through the controller 28, it receives this ball at its tip and swings about the shaft 35 as a fulcrum to detect the safe ball, and an interlocking rod 30 is connected to the swinging rear end. I've let it happen.

The interlocking rod 30 is made of a heavy metal rod, and its upper end is connected to the operating member 23 of the prize ball device.
The weight of this interlocking rod is connected to the detector 29 at all times, that is, when there is no safe ball passing through.
Jump up the tip of the ball and prepare for the passage of the safe ball,
The actuating member 23 is pulled down using its spindle 36 as a fulcrum, and a pin (not shown) installed in the case lid 21 of the award ball case is hooked into the notch 37 formed at the lower edge of the actuating member 23, and the case lid is closed. 21 is restrained in a closed state.

In the figure, reference numeral 38 denotes an out-ball passage with an entrance 40 opened on the chamber 12 side corresponding to the out-ball opening 39 provided in the base frame plate 1, and this passage is entirely connected to the chamber as shown in FIG. Prize ball release path 1 provided on the 13 side
It is arranged so that it is aligned on the same side as 7.

Now, the mechanism frame 9 in which the above-mentioned award ball device, safe ball detection device, interlocking members, etc. are built in has a pivot shaft 41 provided above and below one side edge, and a bearing fitting 42 provided above and below the right edge of the base frame plate 1. It is pivoted so that it can be opened and closed freely by being supported by a shaft, and is normally closed in contact with the back surface of the base frame plate 1 using this pivot portion as a fulcrum. By this closing, in cooperation with the cover 6 and case 7 of the prize ball guiding gutter 5 mentioned above, the window 3 opened in the base frame plate is surrounded all around, and this enclosure and the front side of the base frame plate are A safe ball-closing chamber 44 is formed by the game board 10 that is fitted from the top and a back cover 43, which will be described later.

The back cover 43 is formed to match the size of the safe ball collection chamber 44 surrounded by the cover 6, the case 7, and the mechanism frame 9. It is fixed to the mechanism frame by screwing one side edge to a mounting piece 45 protruding along the side, and the safe ball abutment chamber 4 is fixed to the mechanism frame as the mechanism frame is opened and closed.
The back of 5 can be opened and closed.

In the figure, reference numeral 46 denotes a stop plate that locks the free edge of the back cover 43, which is opened and closed, in a closed state, and 47 is a box for a control electric circuit for operating the winning device attached to this stop plate.

The stop plate 46 is rotatably connected to a pivot joint 48 provided on the inner side surface of the case 7, and when the mechanism frame is closed, the free edge of the back cover 43 is attached to the case 7.
When the back cover comes into contact with a receiving piece 49 protruding from the inner side surface of the back cover, the back cover can be restrained by overlapping the pivot portion 48 on the fulcrum. The electric circuit box 47 is removably fixed to the stop plate 46 with screws, and when the winning device installed on the game board 10 changes due to replacement of the game board 10, the circuit corresponding to this winning device can be installed. It is designed so that it can be easily replaced with the box provided.

In addition, the reference numeral 50 in the figure is a locking device which, together with the stop plate 46, restricts the opening of the mechanism frame 9 when it is closed, and which locks the fan-shaped plate to the upper free end of the mechanism frame 9. It is restrained in a closed state by.

By the way, in the pachinko machine configured as described above, the game board 10 is attached to the front side of the base frame board 1, and the back side thereof faces the window 3. In use, the mechanism frame 9, which is attached to the back surface of the base frame plate via a pivot joint so that it can be freely opened and closed, is always closed in contact with the locking device 50, and is restrained in the closed state. A guide path 14 and a prize ball guide gutter 5 are communicated, and stored prize balls from a storage tank 4 are guided to a prize ball case 15 through the guide path 14, while a safe ball passage 27 is made to face a safe ball collection chamber 44. At the same time, the back cover 43, which is integrally screwed to the mechanism frame 9, is placed over the back of the safe ball-closing chamber 49 to make this chamber into a sealed chamber, and its free edge is placed in contact with the receiving piece 49 provided on the cover 7. A stop plate 46 is placed over the overlapping portion and clamped between the receiving piece and the back cover, thereby restraining the back cover.

Now, in the pachinko machine of the present invention having the above configuration, the balls stored in the storage tank 4 are guided to the prize ball case 15 through the prize ball guiding trough 5 and the guide path 14, where a predetermined number of balls are stored and prepared for release. Then, as the game progresses, the safe ball flies into the safe ball guide, travels through the ball guide frame 31, and transfers into the safe ball passage 27.
First, operate the controller 28, then push down the safe ball detector 29 facing the passage and push up the interlocking rod 30.
The case lid 2 engages with a notch 37 formed in the actuating member 23 supported by the support shaft 36 by swinging it.
The pin 1 is removed, the case lid is opened, and the prize balls stored in the prize ball case 15 are discharged, and the prize balls are sent through the discharge port 25 to the prize ball tray, and at the same time, the actuating member 23 is interlocked with the prize ball tray. The upper part of the prize ball case is closed with the inflow control piece 22, and only the predetermined number of stored prize balls are released.

This prize ball discharge operation is performed once as the detector 29 pressed down by the safe ball returns to its original state, the interlocking rod 30 rises, and the operating member 23 returns to its original state as well. The motion is completed and the ball is ready for the next safe ball to fly in.

The pachinko machine of the present invention is configured as described above, and among the mechanical parts provided on the back side of the base frame plate, the safe ball passage 27 for processing and controlling safe balls, the controller 28, the safe ball detector 29, and Various devices and parts such as operating members that transmit the operation of this safe ball detection system to the winning ball device are housed in a room 12 provided along the back of the base frame board, and these devices and the safe ball approach chamber 44 are placed on the same surface. In line with this, all the mechanisms related to safe ball processing control are housed in one layer along the back of the base frame plate, so balls that have become safe balls are smoothly guided to the exit of the safe ball passage.
During this time, ball clogging will not occur, and at the same time, the prize ball system devices are housed in the chamber 13 of the mechanism frame and are neatly arranged along the back of the layer where the safe ball processing control mechanism is housed. Therefore, the prize ball can be released smoothly as well.

In particular, because the devices of the two systems mentioned above are separated into two vertical layers along the front and back planes, there is no intersection between the flow of the safe ball and the flow of the prize ball. It has the advantage that the various devices of the mechanical section can be installed simply, and furthermore, since all the devices can be contained within two layers, the thickness of the front and back of the entire Pachinko machine can be minimized.

Further, as explained in the above embodiment, the present invention includes a safe ball control device and a prize ball control device that are housed in one mechanical frame and hinged to open and close freely.
This allows one surface along the back of the base frame board, that is, the room 12 side, to be opened and exposed to the front, making it possible to clearly see the parts housed in the two layers. Can be quickly repaired and inspected.

In particular, the safe ball detection device and prize ball device need to be sealed in the assembled state to prevent tampering, but at the same time they are precisely made to react sensitively to balls, so It is easy to cause troubles such as clogging, and there has been a demand for a device that can be opened easily.However, according to the present invention, the sealed state can be immediately released by releasing the locking device, so it is easy to perform not only repair work but also maintenance and inspection work. It is also extremely advantageous.

Since this mechanism frame is pivoted by inserting a pivot shaft 41 provided on the mechanism frame into a bearing fitting 42 provided on the base frame plate, if a malfunction occurs in the entire built-in device, It has become possible to easily remove the entire mechanism frame and replace it with a new one.
