The components of the safe ball detection system and the interlocking device that interlocks both systems are built into one mechanism frame, and this mechanism frame is pivoted to the back of the base frame plate so that it can be freely opened and closed. The present invention relates to a pachinko machine that allows assembly work to be performed efficiently, and maintenance, inspection, and repair work to be performed simply and quickly.

As is well known, pachinko machines, especially detachable pachinko machines in which the game board can be inserted and removed, have the game board removably housed in a base frame that forms the backbone of the device body.
A device that processes safe balls that fly in through the game board, a device that releases a predetermined number of prize balls to the player in response to the safe balls, a device that stores prize balls sent from outside the machine, or stored balls. It is equipped with many parts, such as a ball extraction device that releases water out of the aircraft.

These parts installed on the base frame plate are designed to repeat a certain operation regularly every time a safe ball flies in, and are designed to always release a predetermined number of prize balls, but as the game progresses, The frequency of operation of these parts is extremely high, and the risk of failure is particularly high for the prize ball device that releases prize balls, the safe ball detection device that detects incoming safe balls and prompts the activation of the prize ball device, and surrounding parts. When the temperature is high, damage may occur.

However, in conventional pachinko machines, the parts installed on the back of the base frame board are fixedly attached with screws, etc., which may cause balls to become clogged in the safe ball detection device, for example. , or if the opening/closing operation of the prize ball device stops, it is impossible to quickly inspect the malfunctioning part or replace parts, and the game may be stopped for a long time, or the game may become unusable. There are things to do.

In view of these circumstances, the present invention has been developed to provide systems for prize ball systems such as prize ball devices that operate frequently and always require accurate operation, and safe ball detection systems centered on safe ball detectors. The system device and the interlocking device that connects both devices are housed together in one mechanism frame, and the mechanism frame is installed along one side edge, avoiding the center of the back of the base frame plate, and can be opened and closed freely. A mechanical part of a pachinko machine which is pivotally mounted and whose mechanism frame body is always closed in contact with the back surface of a base frame plate to connect it with related devices such as a prize ball storage device, a safe ball collection chamber, etc., which are installed elsewhere. On the other hand, in the event that a failure occurs inside the mechanism frame, or for maintenance or inspection of internal devices, the back of the base frame plate can be opened using the pivot joint as a fulcrum, and the failure part etc. can be directly repaired. Our goal is to provide pachinko machines with the highest quality.

In addition, in order to effectively achieve the above object, the present invention further includes a safe ball detection device and a prize ball device operating center member on the back side of the mechanism frame (the side facing the base frame plate), and furthermore, the operation center members of the safe ball detection device and the prize ball device are connected to each other.

It is a mechanism frame that integrally incorporates various parts of the prize ball system, including the prize ball ejecting device, and an interlocking device that connects both systems.

The main body of the mechanism frame 6 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 first open side on the back side (the side facing the base frame plate 1) with the substrate 11 in the center, which accommodates the parts of the interlocking device and the safe bulb detection system.
The space part 12 has a two-layer structure in front and back, with a second space part 13 in each longitudinal direction for housing parts of a prize ball system device on the other side.

FIG. 2 is a longitudinal cross-sectional view taken along the center of the mechanism frame 9, particularly the second space 13 in which the prize ball system device is housed; 15 is a prize ball device installed following the meandering part 16 of the supplementary ball guideway 14, 17 is a prize ball ejection path provided below the prize ball device, and 18 is a prize ball release path provided below the prize ball device. This is a ball-extracting gutter installed in parallel.

Prize ball device 15 (hereinafter referred to as prize ball case 15)
is formed into a cylindrical shape, with a piece 19 extending from the side.
The lower end is swingably attached by pivotally connecting the upper end to the base plate 11 with a pin 20, and the opening at the lower end is always exposed to the prize ball discharge path 17 by 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 first space 12 side, so that the actuating member 2 always operates in a fixed relationship.

In addition, in this embodiment, the entire prize ball device includes the prize ball case 15 and the case lid 2 as described above.
1. It is composed of the control piece 22, a part of the supplementary ball guideway 14, and the actuating member 23.

Taxiway 1 from storage tank 4 through ball supply gutter 5
The prize balls guided to the ball 4 enter the prize ball case 15 and are stopped at the position of the lid 21 which closes to 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.

On the other hand, the prize ball discharge 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 is further connected to an overflow ball passage 26. A ball extraction gutter 18 arranged in parallel with 17 is formed as an independent passage so as to reach the lower end of the frame.

27 is a safe ball passage provided on the back side of the substrate 11 in the lower half of the mechanism frame 9, that is, in the first space 12, and 28 is a safe ball passage that allows consecutively flying safe balls to pass one by one. The controller 29 is a safe ball detector that detects safe balls flowing down the safe ball passage 27, and 30 is an interlocking rod that transmits the operation of the safe ball detector to the operating member 23 of the prize ball device.

The safe ball passage 27 opens and communicates with a sloped ball shifting frame 31 formed by the lower upper edge of the case 7 and the lower upper edge of the mechanism frame, and communicates with the controller 28.
is installed facing the upper folded part of this safe ball passage.

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 have let you.

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, 38 is a detection plate for detecting when a predetermined number of prize balls cannot be supplied to the prize ball case 15 due to a shortage of prize balls in the ball catching guide path 14, and 39 is a detection plate for detecting a shortage of prize balls. A swinging rod that restricts the operation of the interlocking rod 30 when detected, 40 is a swinging rod and an actuating member 2.
It is a link that connects 3.

The detection plate 38 is formed in an L shape, and is connected to the substrate 11.
The detection piece 38a is always placed facing the guideway 14, and if there is a prize ball on it, it is pushed up with the diameter of the ball. , if it is missing, the taxiway 1 will be closed under its own weight.
4, and the stopper piece 38b is made to slip under a pin 42 provided at one end of the swinging rod 39 to prevent its descent. The swinging rod 39 is supported on a support shaft 43 installed on the side of the first space 12 so as to be freely swingable. When the guiding path 14 is filled with prize balls and the detection plate 38 is pushed up and is operating normally, the swinging rod 39 moves the operating member 23 by the vertical movement of the interlocking rod 30.
When the detecting piece 38a of the detecting plate is lowered, that is, when the prize ball is not caught, the stopper piece 38b is moved under the pin 42. This prevents the swinging movement of the ball, thereby restraining the operation of the actuating member 23 and stopping the ejection of the prize ball. Therefore, when a shortage of prize balls is stored in the prize ball case due to the function of this device, the prize balls will not be released in the missing state.

Now, the mechanism frame 9 in which the above-mentioned prize ball device, safe ball detection device, interlocking device, etc. are housed in the first space and the second space has pivot shafts 44 and 45 provided at the top and bottom of one side edge. It is pivoted to open and close freely by being supported by bearing fittings 46 and 47 provided on the upper and lower right side edges of the base frame plate 1, and is normally in contact with the back surface of the base frame plate using this pivot point as a fulcrum. Closed together.
By this closing, in cooperation with the cover 6 and case 7 of the ball supply gutter 5 described above, the back of the window 3 opened in the center of the base frame plate is surrounded all around, and this surrounding A safe ball collection chamber 49 is formed by the game board 10 that is fitted from the front of the base frame board, and a back cover 48 that will be described later.

The back cover 48 is formed to match the size of the safe ball collection chamber 49 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 50 protruding along the edge), and opens and closes the back of the safe ball gathering chamber 49 as the mechanism frame opens and closes. It is now possible to do so.

In the figure, reference numeral 51 denotes a stop plate that locks the free edge of the back cover 48, which opens and closes, in a closed state, and 52 is a box for a control electric circuit for operating the winning device attached to this stop plate.

The stop plate 51 is rotatably connected to a pivot joint 53 provided on the inner side surface of the case 7, and when the mechanism frame is closed, the free edge of the back cover 48 is brought into contact with the inner side surface of the case 7. When it comes into contact with a receiving piece 54 protruding from the back cover, the back cover can be restrained by overlapping the pivot portion 53 on the fulcrum. The electric circuit box 52 is removably fixed to the stop plate 51 with screws, and when the winning device installed on the game board 1 changes due to replacement of the game board 1, it is equipped with a circuit corresponding to this winning device. It is designed so that it can be easily replaced with a new box.

On the other hand, the reference numeral 55 in the figure is a locking device which, together with the stop plate 51, restricts the opening of the mechanism frame 9 when it is closed.

As shown enlarged in FIGS. 7 to 9, this locking device 55 includes a rotating locking plate 57 rotatably supported by a support shaft 56 at the upper part of the outlet of the ball supply gutter 5 fixed to the base frame plate 1. , a stopper member 58 that moves up and down in conjunction with the rotation of the lock plate to open and close the outlet of the ball supply gutter 5. Rotating lock plate 5
7 is a long hole 59 inclined in the plate portion formed in a substantially fan shape.
A box 60 of the stopper member 58 is slidably connected to this elongated hole, and when locking, the handle 61 is raised vertically and a part of the locking plate 57 is projected in front of the ball supply gutter 5. Mechanism frame 9 assembled in a butt-like manner at the tip of this supply gutter
It is configured to engage with an engaging portion 62 provided at the upper free end of the holder to restrict its opening.

FIGS. 7 and 8 show this restrained state. At this time, the stopper member 58 rises and lifts its lower end from the outlet of the ball supply gutter 5, and connects it to the ball catching guide path 14 of the mechanism frame 9 facing this outlet. It is designed to communicate.

In this state, when the handle 61 is next tilted to the right, the protruding portion of the lock plate 57 retreats from the engagement portion 62 of the mechanism frame, disengages it, and at the same time frees the mechanism frame to open. As the lock plate 57 rotates, the elongated hole 59 pushes down the boss 60 that slides into it, so the stopper member 58 descends, closing the ball supply gutter 5 and stopping the flow of the prize balls stored.

That is, the locking device 55 equipped with the stopper member 58 normally restrains the mechanism frame 9 in the closed state, and connects the supplementary ball guide path 14 to the ball supply gutter 5 fixed to the back surface of the base frame plate to store the balls. The ball is set to be able to be supplied to the winning ball device, and when the mechanism frame is released from the back of the base frame plate 1 if necessary, the lock plate 57 is rotated to disengage from the engaging portion 62 and the ball is released. At the same time, the stopper member 58 is lowered to close the ball supply gutter 5, thereby preventing balls from flowing out from the gutter, which opens when the mechanism frame is opened.

In addition, in the figure, 63 is a prize ball discharge path 17 in a prize ball tray attached to the front of the base frame board 1, a discharge port opened in the base frame board for sending out prize balls released through the window 25, and 64 is a discharge port opened in the base frame board 10. A through hole is formed in the base frame plate to communicate with the out ball opening of the mechanism frame, and this through hole communicates with an out ball passage 65 provided vertically in the lower part of the mechanism frame.

Now, in the pachinko machine constructed as described above, a game board 10 is mounted on the front side of the base frame board 1, and the back side faces the window 3 as shown in FIG. In use, the mechanism frame 9, which is attached to the back of the base frame plate via a pivot joint so that it can be opened and closed, is always closed in a tangential manner, and the locking device 55 is engaged to restrain it in the closed state ( (See Figure 2) The supplementary ball guide path 14 and the ball supply gutter 5 are connected to each other, and the stored prize balls from the storage tank 4 are guided through the guide path 14 to the prize ball case 15, while the safe ball passage 27 is connected to the safe ball collection chamber. 49. At the same time, in the embodiment described above, the back cover 48, 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 the end edge of the back cover 48 is attached to the cover 7. Piece 54
The back cover is restrained by placing the stop plate 51 over the stack and sandwiching it between the back cover and the receiving piece (see FIG. 4).

As described above, in the pachinko machine of the present invention, the balls stored in the storage tank 4 are led to the prize ball case 15 through the ball supply gutter 5 and the guide path 14, where a predetermined number of balls are stored and prepared for release. When a safe ball flies into the safe ball passage during the game, passes through the ball collection room frame 31 and enters the safe ball passage 27, first the controller 28 is activated, and then the safe ball detector 29 facing the passage is activated. Press down to push up the interlocking rod 30, and press the support shaft 36.
The pin of the case cover 21 that is engaged with the notch 37 formed in the operating member 23 is swung, and the case cover is opened to open the prize ball case 15.
The prize balls stored inside are released and sent out to the prize ball tray through the window 25 and the discharge port 63, and at the same time, the inflow control piece 22 interlocked with the operating member 23 closes the upper part of the prize ball case, and the ball is stored. Only a predetermined number of prize balls will be 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 descends, and the actuating 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 includes a safe ball detection device that operates frequently during games,
If a malfunction occurs in the winning ball device, etc., the lock device 5
5. By disengaging the stop plate 51, the mechanism frame 9 containing these devices is released from the back of the base frame plate 1 using the pivoting part as a fulcrum, and the mechanism frame 9 in which the operating mechanism part is installed is opened. Since the first space 12 can be exposed to the front, repairs and inspections can be carried out extremely quickly through the opening of this space.

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.

This mechanism frame is attached to bearing fittings 46, 47 provided on the base frame plate and pivot shafts 44, 4 provided on the mechanism frame.
Since it is pivotally attached by inserting 5, it is possible to easily remove the entire mechanism frame and replace it with a new one in the event that a malfunction occurs in the entire built-in device. ing.

On the other hand, as described in detail in the embodiment, the mechanism frame 9 in the present invention is made of plastic and has a second space 13 on one side of the substrate 11 as the center.
