Description

[Detailed Description of the Invention] The present invention relates to a coin gaming machine, and particularly to a coin gaming machine that allows ball hitting games or other various games to be played in response to the insertion of a predetermined number (or a specified number) of coins required for one game. This invention relates to improvements to coin-operated gaming machines.

In general, coin gaming machines have become widespread and are popular among players as a convenient form of leisure.

As is well known, coin gaming machines hit pachinko balls (hereinafter referred to as "balls") only for a fixed number of balls or for a fixed period of time in response to the insertion of a predetermined number of coins required for one game (hereinafter referred to as the "required number"). It is played by playing the game.

In such a coin gaming machine, for example, a plurality of ball sockets are formed horizontally below the game board, and a plurality of winning holes are formed on the game board surface as necessary.

Then, depending on the combination of the ball sockets into which the balls hit by the player fall, points are awarded and prizes (for example, coins) are paid out according to the points.

In addition, coin gaming machines using other gaming methods have multiple winning holes (safe holes or winning ball devices) arranged on the game board, and prizes are awarded based on the balls or number of balls that hit the winning holes. It is something to pay out.

By the way, conventional coin gaming machines have the disadvantage that if more coins than are required for one game are inserted, all the coins are taken in, causing a loss to the player.

Therefore, even if the player accidentally inserts more than the required number of coins, it is desirable to prevent the player from being disadvantaged by returning more than the required number of coins.

Therefore, in order to meet the above-mentioned demands, conventionally, a stopper (or shutter) is provided in conjunction with the coin slot of a coin game machine, and when a predetermined number of coins are inserted, the stopper closes the coin slot. , the insertion of coins was prohibited.

However, some players sometimes try to forcefully insert coins even though they have inserted the required number of coins.

For this reason, there was a problem in that the stopper of the coin insertion slot was deformed and a failure was likely to occur.

Another method is to provide a stopper in connection with the path for collecting coins from the coin slot, and to stop the inserted coins with the stopper after the required number of coins have been inserted.
In some games, when the player presses the return button, the bottom of the passage is opened and the inserted coins are returned from the return slot.

However, with such a structure, the player has to press a return button in order to return more coins than the required number, which is a problem in that the operation is cumbersome.

Furthermore, such coin gaming machines also have the problem that if more coins than the required number are inserted, the collection passage becomes clogged, causing a malfunction.

Therefore, this invention was made to solve the problems of the conventional ones as described above, and when more coins are inserted than the number required for one game, the number of coins exceeding the required number is To provide a coin game machine that prevents failure and eliminates troublesome operations for returning coins by returning them using a prize coin dispensing device.

To summarize, this invention is designed to return coins in excess of the required number to the player using a prize coin dispensing device when more coins than the required number are inserted to play one game. It is.

4A to 4D are illustrative views of the coin guiding and sorting mechanism, in particular, FIG. 4A shows a perspective view thereof, FIG. 4B shows a front view seen from the front side of the coin gaming machine 10, and FIG.
Figure C shows the right side view, and Figure 4D shows the D shown in Figure 4C.
-A cross-sectional portion along D' is shown.

Next, the configuration of the coin guiding and sorting mechanism 40 will be explained with reference to FIGS. 4A to 4D.

The coin slot 3 is attached to the front grade 41 so as to be inclined slightly to the right with respect to the vertical direction.

A coin guide passage 421 is formed below the coin slot 3 so as to be inclined downward.

This coin guide passage 421 is supported by two plate-like members 431 and 432 facing each other with an interval slightly larger than the thickness of one coin and tilting slightly to the right of the vertical direction.

One plate member 432 is fixedly supported by the front plate 41.

The other plate-like member 431 is fitted into a recess formed in the plate-like member 432 with its upper part cut and raised.

The upper portions of both plate members 431 and 432 have a cross section of C.
It is elastically biased by a shaped spring 433.

A parallelogram-shaped opening 434 parallel to the bottom surface of the guide passage 421 is formed on the side surface of the plate member 431 .

In addition, a plate member 43'2 facing the lower side of the opening 434
A bottom portion 435 of the coin guide passage 421 is formed in the bottom portion 435 of the coin guide passage 421.

This bottom portion 435 has a plate member 43 along the inclination direction.
A groove 43'6 is formed from one side of the coin to allow defective coins, which are slightly thinner than the thickness of a regular coin, to fall into.

Further, at the top of the plate-like member 431, a bottom 435 is provided with a distance slightly smaller than the diameter of a regular coin from the bottom 435.
A large detection piece 437 extending parallel to 35 is attached so as to be slidable in the vertical direction.

As a result, defective coins having a diameter smaller than the length from the bottom portion 435 to the lower side of the size detection piece 437 are removed from the opening 434 to the outside when passing through the coin guide path 421.

A defective coin guide 438 is formed on the side of the opening 434 to receive small defective coins having such a shape.

This defective coin guide 438 has a stopper piece 4 which will be described later.
53 into and out of the coin guide passage 421
9 is drilled.

Furthermore, a stopper piece 453 (described later) is provided on the plate member 432.
An opening 440 is formed that is slightly larger than the regular coin shape in the portion facing the opening 440 and slightly larger than the radius of the coin in the diagonally upward direction.

A weight detection piece 441 is swingably attached to this opening 440.

This weight detection piece 441 forms a hook-shaped part at a height position of the radius of the regular coin from the bottom part 435, inserts the hook-shaped part into the coin guide passage 421, and is swingably supported at the upper part of the hook-shaped part. It is constructed so that the weight applied to some parts can be adjusted as necessary.

When a regular coin passes through the coin guide path 421, the weight detection piece 441 is pushed outward (to the right in FIG. 4D) and allows the regular coin to pass.

On the other hand, when a defective coin whose weight is lighter than a regular coin passes, the weight detection piece 441 remains inserted into the coin guide passage 421 against the force of the defective coin trying to roll through the coin guide passage 421. This will stop bad coins.

A defective coin guide path 422 is provided below the coin guide path 421 for guiding defective coins to the coin return port 5.

A cut and raised piece 442 is provided on the plate member 431 corresponding to the arrangement position of the coin return button 4.
It is formed so that it touches the rear end of the body at a certain angle.

As a result, when the return button 4 is pressed, the rear end of the return button 4 pushes the cut and raised piece 442, and the lower side of the plate member 431 is pushed out against the spring 433, causing the coin guide path 421 to The coins stopped by the coin guide 438 are dropped into the defective coin guide path 422.

At the end of the coin guide passage 421, there is a coin guide passage 4 for guiding regular coins along the vertical direction.
23 are provided.

A stopper mechanism 45 is installed at an upper position of the coin guide passage 423 on the side of the plate member 431.

This stopper mechanism 45 includes an electromagnet 451 and a support portion 452.
are integrally provided, and this support portion 452 supports the stopper piece 45.
3 is rotatably supported.

The stop collar piece 453 is bent into a V-shape such that its tip (bending portion 455) has a certain angle with respect to the coin passing direction passing through the coin guide passage 421. configured.

The bent portion at the tip of this stopper piece 453 is connected to the opening 4.
39 and is inserted from the bottom 435 of the guide passage 421 to a position slightly below the top position by the radius of the coin.

When the electromagnet 451 is not excited, the stopper piece 453 is pulled by the elastic force of the spring 454 and inserted into the coin guide passage 421.

On the other hand, the other part of the stopper piece 453 is attracted by the excitation of the electromagnet 451 and pulled out from the coin guide passage 421 and the defective coin guide 438.

A notch 443 is formed in the lower part of the coin guide path 423 along the falling direction of the coin.

A detection lever 461 of the inserted coin detection switch 46 is inserted into the notch 443 to detect whether a genuine coin has been inserted.

The coin guiding and sorting mechanism 40 configured as described above always keeps the electromagnet 451 energized and waits for a coin to be inserted with the bent portion 455 of the stopper piece 453 pulled out from the coin guiding path 421.

If the inserted coin is a defective coin, it is detected by the size detection piece 437, the weight detection piece 441, or the defective coin falling groove 436 for detecting the thickness, and is passed through the defective coin guide path 422. The coins are returned from the coin return slot 5.

On the contrary, when a regular coin is inserted, the coin is guided through coin guide passages 421 and 423 and led to the coin chute 211 shown in FIG. 2 described above.

At this time, if a legitimate coin is inserted, the coin detection switch 46
Detected in

FIG. 5 is a specific electrical circuit diagram of one embodiment of the present invention.

This implementation sequence includes an inserted coin detection means 51 including the inserted coin detection switch 46 and an addition/subtraction counter 511;
A game skill activation circuit 52, a game state detection circuit 53, a score counting circuit 54, a pulse generation circuit 55, and a coin payout control circuit 5
6, and a stop control circuit 5.
It consists of 7.

Next, with reference to FIGS. 1 to 5, the operation when playing a game with the coin gaming machine 10 of this embodiment will be explained together with the specific configuration shown in FIG.

Normally, in coin gaming machines, termination control is performed when a predetermined relatively large number of coins are paid out as prizes.

However, when the abort control is not reached or after the abort is released, the flip-flop 572 is reset by suppressing the abort release switch 571.

Therefore, during the period in which games can be played with the coin game machine 10, the flip-flop 572 continues to derive a reset output and provides the output to the driver 573.

The driver 573 operates the electromagnet 4 during a period in which games can be played with the coin game machine 10, that is, during a period when the stop control is not performed.
51 is continuously energized.

As a result, the stopper piece 453 of the coin guide and sorting mechanism 40 is pulled out from the coin guide passage 421, allowing coins to be inserted.

In the state where the game is possible as described above, the player inserts the number of coins required for one game before playing the game.

For example, if the number of cards required for one game is 1,
One coin is inserted into the coin insertion slot 3.

This inserted coin is coin guide passage 421, 423
The coins are stored in the coin storage tube 221 via the coin chute 211.

At this time, the inserted coin detection switch 46 detects the insertion of a coin and derives one pulse, and the addition/subtraction counter 51
Give to 1.

In response, the addition/subtraction counter 511 sets its count to 1.

The count value of the addition/subtraction counter 511 is
2.

This comparison circuit 521 is supplied with information indicating the number of coins required for one game (B = 1 coin) set by the required number setting section 522, and the information representing the number of coins required for one game (B = 1 coin) is supplied to the comparison circuit 521. Reset output q
is given as a comparison command signal.

Therefore, when the count value A of the addition/subtraction counter 511 is inputted to the comparator circuit 521 at the end of the game, the comparator circuit 521
and the required number B, and the counted value is greater than or equal to the required number (A≧B)
High level when . A signal (hereinafter referred to as "H" signal) is derived and applied to the monostable multi 524.

In response, the monostable multi 524 remains “H” for a certain period of time.
'' signal is derived and given as a gate opening command signal to the gate circuit 525.

In response to this, the gate circuit 525 is opened. The required number B set in the required number setting section 522 is added to and subtracted from the counter 5.
11 negative information (that is, subtraction information).

As a result, the addition/subtraction counter 511 subtracts the required number from the number of coins inserted, and obtains the difference (usually O).

In addition, the rHJ signal of the monostable multi 524 is OR tart 5
Coin payout control circuit 56 and delay circuit 59 via 8
give to

When the coin payout control circuit 56 receives the "H" signal from the OR gate 58, it controls the payout of prize coins based on the points counted by the score counting circuit 54, but in the initial state, the points are not counted. The count value of circuit 54 is 0
Therefore, no coin payout control is performed.

Furthermore, the "H" signal of the monostable multi 524 is transmitted to the delay circuit 5.
26.

The delay circuit 526 derives the "H" signal after a certain time delay,
It is applied to the set input terminal of driver 527 and flip-flop 523.

The driver 527 energizes the solenoid 254 for a certain period of time.

In response, the solenoid 254 attracts the plunger and pulls the lever 253, thereby rotating the rotary shielding plate 251 and causing the balls stored in the vertical paths 32a to 32p to fall into the path 33.

A ball dropped into this passage 33 is guided to the ball waiting gutter 15.

This allows the player to play a ball hitting game with a constant number of balls.

Then, the player operates the ball hitting handle 16 to adjust the strength of the ball to be hit and issue a command to hit the ball as appropriate.

As a result, the balls guided to the ball waiting gutter 15 are sequentially hit one by one by the electric ball hitting mechanism and are driven into the game board 7.

This ball is placed in the special prize hole 9j, 9g or the winning ball device 9f,
9k or replay hole 9R, or directly into any of the ball sockets 8a to 8p without falling into these holes.

Now, assume that the ball falls into the ball socket 8a.

In order to guide the falling ball to the vertical passage 32a through the ball socket 8a, the lever 311 of the detection switch 31a is pressed.

In response, the detection switch 31a is closed and the display section 11a is lit.

Thereafter, in the same manner, when the ball falls into one of the ball sockets or the winning ball device, the detection switch corresponding to the ball socket into which the ball fell is closed, and the ball is placed in the ball socket. The corresponding display section lights up.

As described above, the output of each detection switch 31a to 31p corresponding to the ball socket where the ball fell is detected by the gaming state detection circuit 5.
3.

This combination establishment detection circuit 530 is composed of, for example, a combination matrix circuit, and is configured to detect the establishment of each combination in one vertical column, each combination in one horizontal row, or the four combinations in the center of the combination display 11. It is composed of

For example, when a combination in the leftmost vertical column is established, the rHJ signal is continuously derived from the output terminal corresponding to the combination, and the rHJ signal is sent to the differentiating circuit 531 and the score display driving circuit 6.
Give to 1.

The differentiating circuit 531 differentiates the rHJ signal at the rising edge and supplies the differentiated pulse to the score counting circuit 54 via the OR gate 53a as a signal for instructing to add one point.

In response, the score counting circuit 54 adds one point to the score based on the establishment of a combination in one vertical column, and provides the number of scores to the decoder 62.

The decoder 62 provides a decoded output of numerical information corresponding to the number of points counted by the score counting circuit 54 to the numerical display 12, thereby causing the numerical display 12 to display the score.

At the same time, the score display drive circuit 61 lights up the display section 131 corresponding to the score (1 point) that will be awarded when the combination in the leftmost vertical column is established.

Further, when the combination in the horizontal row at the top is established, the combination establishment detection circuit 530 outputs an "H" signal from the corresponding output terminal.
The signal is derived and given to the differentiation circuit 535.

The pulse differentiated by this differentiation circuit 535 is output to the OR gate 5
3b to the score counting circuit 54 as a pulse input representing two points.

Furthermore, when a combination of the four central display sections is established, an "H" signal is derived from the corresponding output terminal and provided to the differentiating circuit 539.

Differentiating circuit 539 differentiates the rising edge of the "H" signal and supplies it to score counter 54 as score pulses representing three points.

In this way, points are awarded depending on the combination of ball sockets into which the balls have fallen, and the points are counted by the score counting circuit 54.

Further, the score display section for each combination is displayed by lighting up.

By the way, when the ball lands in the special prize hole 9j or 9g, the ball is detected by the special prize ball detection switch 241 or 242 as it passes through the passage 231 or 232 on the back side, and then the ball corresponding to the special prize hole is detected. It is guided to the vertical passage 32j or 32g on the back side of the socket.

As a result, the display section 11j or 11g corresponding to the special prize hole 9j or 9g is lit and displayed, and one pulse derived by closing the special prize ball detection switch 241 or 242 is sent to one point via the OR gate 53a. It is added to the score by the score counting circuit 54 as a pulse that gives .

Therefore, when a prize is won in the special prize hole, points corresponding to the special prize hole are awarded to the player even if no combination is established.

As described above, when a certain number of balls have been hit during the ball hitting game, a game end signal is derived by an appropriate detection means.

This game end signal causes the 7 flip-flop 523 to be reset.

If the player wishes to continue playing the game, he or she inserts the required number of coins into the coin slot 3 again.

Accordingly, the desired number of copies can be created in the same manner as described above.
It is determined that the input has been input, and the monostable multi 524
again derives the rHJ signal.

This "H" signal is applied to the coin payout control circuit 56 and the delay circuit 59 via the OR gate 58.

At this time, the coin dispensing leg circuit 56 is connected to the score counting circuit 54.
Based on the score counted in the solenoid 22
3 is energized intermittently to control the payout of the number of coins according to the score.

Thereafter, the delay circuit 59 delays opening for a certain period of time and resets the score counting circuit 54.

Note that if the player wishes to finish the game without continuing the game, he or she presses the settlement button 6.

In response, the OR gate 58 derives an "H" signal and supplies it to the coin payout control circuit 56, thereby controlling the payout of the number of coins corresponding to the points earned in the previous game.

Next, the operation when more coins than the number required for one game are inserted, which is a feature of the present invention, will be explained.

For example, assume that a player accidentally inserts three coins even though the required number for one game is one.

Now, when three coins are inserted, the inserted coin detection switch 46 outputs three pulses, and the addition/subtraction counter 51
Give to 1.

In response, the addition/subtraction counter 511 sets its count to three.

This count value (A=3) is given to comparison circuit 521.

The comparator circuit 521 detects that more than the required number (B=1) of coins have been inserted and sends an "H" signal to the monostable multi 524.
give to

When the monostable multi 524 derives the rHJ signal for a certain period of time, the gate circuit 525 is opened and the required number B is given to the addition/subtraction counter 511 as subtraction information.

Therefore, the addition/subtraction counter 511 counts the number of coins inserted (A=
3), the required number (B=1) is subtracted (3-1) and the subtracted value is given to the pulse generation circuit 55.

At this time, the pulse generating circuit 55 does not perform any operation since it has not yet been given the activation signal.

Then, after the monostable multi 524 derives the rHJ signal, the delay circuit 526 conducts the rHJ signal after a certain period of time to set the flip-flop 523, and the set output is sent to the pulse generation circuit 55 as an activation signal. Given.

Accordingly, the pulse generation circuit 55 adds and subtracts the counter 511.
The number of pulses corresponding to the count value is derived and given to the coin payout control circuit 56 as a coin payout command pulse.

In response to this, the coin payout control circuit 56 intermittently energizes the solenoid 223 a number of times corresponding to the number of pulses input from the pulse generation circuit 55, and collects coins equivalent to the number of coins inserted in excess of the required number. The payout is controlled using the prize coin payout mechanism 22.

At the same time, the output pulse of the pulse generating circuit 55 is applied as a subtraction input pulse to the addition/subtraction counter 511.

The addition/subtraction counter 511 subtracts the number of pulses given from the pulse generation circuit 55.

In this way, even if the player accidentally inserts more coins than are required for one game, the coins can be automatically returned using the prize coin payout mechanism 22.

In this way, there is no disadvantage to the player, and there is an advantage that malfunctions such as coin jams can be reduced compared to the case where a stopper piece is provided in the coin slot.

Furthermore, since prize coins are paid out from the coin payout port, coins that are not used for games are always stored in the coin tray.

Therefore, it is possible to prevent the player from leaving the coin gaming machine forgetting that the coin has been returned to the coin return slot, and to prevent the player from being disadvantaged as much as possible.

In addition, in this implementation row, the combination status on the combination display 11 is displayed on the score display 13 including a display section for each combination, and this display status continues even after the number of coins corresponding to the score is paid out. To prevent trouble between an attendant and a player when the number of coins corresponding to the points obtained in one game is not paid out.

In that case, an electromagnetic counter may be provided to count the coins paid out from the coin payout mechanism 22 for each game, if necessary.

In addition, if the coin gaming machine 10 pays out more coins than the predetermined number of coins, the following procedure will be performed. Abort control is performed.

That is, in this case, the stop switch 574 is closed either manually by an attendant at the game parlor or automatically when it is detected that coins have been paid out as prizes equal to the number of coins to be stopped.

In response, flip-flop 572 is set and provides the set output to driver 575.

The driver 575 lights up the end indicator 14 to notify that the process has been discontinued.

At the same time, the reset output of the flip-flop 572 becomes a low level signal, so the driver 573 de-energizes the electromagnet 451.

Accordingly, the bent portion 455 of the stopper piece 453 is inserted into the coin guide passage 421 to prevent coins from being accepted thereafter.

Therefore, after the termination control, the inserted coins are returned from the coin return port 5 through the opening 440 and the defective coin guide path 422, and the game is prohibited.

As described above, according to the present invention, a player can
Even if you insert more coins than the required number for the game, by using the prize coin payout mechanism to return the excess number of coins, you will not be disadvantaged by the player, and you will be able to use the coin input slot. It has unique effects such as being able to prevent malfunctions if coins become jammed.
