Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pachinko machine, and more particularly, to a pachinko machine in which the operation of a prize ball dispenser can be reliably detected.

[Conventional technology]

As is well known, pachinko machines are equipped with a prize ball dispenser that operates every time a safe ball is obtained and dispenses a fixed number of prize balls. Such a prize ball dispenser is known, for example, from Japanese Utility Model Application Publication No. 60-25678,
It has a storage section that stores a certain number of prize balls supplied from the prize ball tank. When a safe ball is detected, the entrance of the storage section is closed and the exit of the storage section is opened to pay out a certain number of prize balls all at once.

Further, in consideration of the case where safe balls occur continuously during one payout operation period of the prize ball dispenser, the operation of the prize ball dispenser is electrically controlled. That is, each time a safe ball is detected, the number is counted by a counter, and a solenoid for operating a prize ball dispenser is repeatedly driven until the count value of this counter reaches rOJ. Each time the prize ball dispensing device performs one dispensing operation, the count value of the counter is subtracted by 1, and when the count value of the counter reaches "0", the solenoid is driven. It will stop and go into standby mode.

[Problem that the invention seeks to solve]

By the way, in conventional pachinko machines, in order to detect that the prize ball dispenser has performed a single dispensing operation, the movement of a lever, etc. that is moved by the drive of a solenoid is detected using a photo sensor, micro-sinch, etc. I try to do that. For this reason, for example, if the prize ball tank is empty or a ball is jammed in the path from the prize ball tank to the prize ball dispenser, and the prize balls are not actually paid out. However, − times of payouts will be detected. As a result, the counter that counts the number of safe balls is subtracted, and the number of safe balls does not correspond to the number of prize balls to be paid out.

The present invention has been made to solve the above-mentioned drawbacks of pachinko machines, and is designed to prevent erroneous detection when a prize ball is not actually paid out even if the prize ball payout device operates. The purpose is to provide a pachinko machine with the following features.

Means for Solving Problem C] In order to achieve the above object, in the pachinko machine of the present invention, by detecting the prize balls paid out from the prize ball payout device, It uses a dispensing detector that detects operation. Each time the payout detector performs one count, the count value of the counter that counts the number of safe balls is subtracted by one. That is, instead of detecting the prize balls paid out from the prize ball dispensing device individually, one detection is performed when the prize balls are paid out all at once. therefore,
When consecutively putting out prize balls, it is possible to do so in a short time without interfering with the function of paying out and putting out a fixed number of prize balls at once.

In a preferred embodiment of the present invention, a lamp for confirming and displaying the payout of prize balls is also activated using the signal from the payout detector, so the configuration is simpler than that of the conventional payout confirmation display device. ing. As in the embodiment described later, the payout detector includes a lever that swings once due to the prize balls flowing down all at once from the prize ball payout device, and a switching means that electrically detects the swing of this lever. It is easy to configure from

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

In FIG. 5, which shows the front appearance of a pachinko machine using the present invention, pachinko balls 2 shot out by operating a handle 1 flow down a game board 3. As is well known, the game board 3 has a safe hole 4. Tulips 5, as well as obstacle nails, windmills, etc. (all not shown) are provided. Then, in the middle of the flow, there is a safe hole 4. Balls other than safe balls that have won prizes such as Tulip 5 flow into the out hole 6. When a safe ball is generated, a prize ball dispensing device, which will be described later, is operated and a fixed number of prize balls are dispensed to the upper dispensing lower or the ε upper tray 8. When the upper tray 8 is full of prize balls, the prize balls are dispensed from the lower dispensing port 9 to the lower tray 10.

In addition, a prize ball shortage indicator lamp 1 is placed around one side of the game board 3.
1. Payout indicator lamp 12. A credit lamp 13 is provided. The prize ball shortage indicator lamp 11 lights up when a sufficient amount of prize balls to be paid out when a safe ball occurs is not prepared in a prize ball tank 1B (see FIG. 1) to be described later. The payout indicator lamp 12 lights up when a prize ball is paid out, and the credit lamp 13 lights up until the payout of prize balls corresponding to the number of safe balls is completed when safe balls occur consecutively. It will be lit.

As shown in FIG. 1, a back mechanism frame 14 is attached to the back of the game board 3, and the safe ball that has entered the safe hole 4 or tulip 5 is passed through the exit passage 15 to the back set plate. The bulbs are sent in bulk to a safe ball passage 16 attached to a tube 18. In the middle of this safe ball passage 16, there is a
A safe sphere detector 17 made of, for example, a photo sensor is provided.

A back set plate 18 is further attached to the back side of the game board 3 so as to be openable and closable. Back set I! j18 includes a prize ball tank 20 that accommodates a large number of prize balls 19, and a gutter 21 for supplying prize balls. A prize ball dispenser 22 and the like are attached. Furthermore, the back set plate 18 has a gutter 23 that forms a ball extraction passage. A gutter 24 is provided for delivering the prize balls 19 dispensed from the prize ball dispensing device 22 to the upper dispensing lower or the lower dispensing port 9. A gutter 25 communicating with the out 66 is connected to the gutter 23 forming the cutout passage.

A lever 26 biased counterclockwise by a spring is pivoted on the left end side of the gutter 21. This lever 26 is
The weight of the prize ball 19 causes it to rotate clockwise against the spring bias. When the lever 26 is rotated clockwise by the prize ball 19, the microswitch 27 is turned on. Further, a ball outlet is formed in a part of the gutter 21, and is normally covered by an opening/closing plate 28. When the opening/closing plate 28 is opened by a ball extraction operation, the prize balls 19 stored in the prize ball tank 20 are collected through the gutter 23.

A payout detection lever 30 is further rotatably attached to the back set plate 18. One end of the payout detection lever 30 faces below the prize ball payout device 22, and a weight 31 is fixed to the other end. This payout detection lever 30 is
In a normal state, it is in a left-rotated position due to the weight 31, comes into contact with a stopper 32 and stops, and the microswitch 33 is in the OFF state. Then, when the prize ball payout device 22 is activated and the prize balls 19 stored there are paid out all at once, the payout detection lever 30 rotates to the right due to the weight of the prize balls 19, and the micro switch 33 becomes ON.

When the prize balls 19 are paid out from the prize ball payout device 22, the prize balls 19 of a certain value are moved to the payout detection lever 30.
Since the coins fall all at once, the microswitch 33 remains in the ON state until the - payout is completed.

In FIGS. 2 and 3 showing the front and partially broken side surfaces of the prize ball dispensing device 22, the prize balls 19 supplied from the gutter 21 are rectified into two rows, and the prize balls introduced into the inlet 34 19 is a storage part 36a after passing through introduction passages 35a and 35b.

36b. The opening 3 is located below each of the outer peripheral walls 37a and 37b forming the storage portions 36a and 36b.
8a and 38b, but both ends are connected to the shaft 39.
When the swing plate 40, which is pivoted by the pivots a and 39b, is in the position shown in FIG. 2, the openings 38a and 38b are closed, so the prize balls 19 in the storage portions 368 and 36b will not fall.

A stop plate 42 is rotatably attached to an upper plate 41 covering the upper surfaces of the storage portions 36a and 36b via a shaft 43. In a normal state, the stop plate 42 is Located in the position shown in FIG. 2, the introduction part 35a
, 35b and the storage portions 36a, 36b. Therefore, the prize balls 19 sent through the entrance 34 are held continuously upwards, with the nest 45 fixed to the lower part of the storage parts 35a, 36b serving as the bottom.

A step portion 47 having a stopper and a pin 46 is fixed to the upper surface of the swing plate 40. When the control plate 50, which is rotatable about the shaft 48 implanted in the upper plate 41, is located on the upper surface of the step portion 47, the swing plate 40
is held in the position shown in FIG. The control plate 50 is interlocked with the stop plate 42 via a link lever 51. That is, when the solenoid 52 attached to the upper plate 41 operates and the solenoid arm 53 protrudes, the stop plate 4
2 is swung to the position shown in FIG. 3 against the spring 44, and the control plate 50 is rotated to the left via the link lever 51.

When the solenoid 52 is driven, the stop plate 42 passes through the opening 41a formed in the upper plate 41 to the introduction parts 35a and 3.
5b and the storage parts 36a and 36b.

As a result, the prize balls 19, including the prize balls 19a and 19b shown in FIG. be done. Further, when the control plate 50 rotates to the left and escapes from the stepped portion 47 as the stop plate 42 swings,
The swing plate 40 swings as shown in FIG. 3 due to the weight of the prize balls 19 in the storage parts 36a and 36b, and falls downward.

When the prize balls 19 in the storage sections 36a' and 36b are discharged in this manner, the swing plate 40 returns to the position shown in FIG. 2 due to its own weight. When the solenoid 52 stops driving, the stop plate 42 is returned to the position shown in FIG. 2 by the bias of the spring 44. As a result, the control plate 50 rotates and returns to the upper surface of the stepped portion 47, and after regulating the rocking of the rocking plate 40, the prize balls 19 after the prize balls 19a and 19b are returned to the storage portion 36a. , 36b, and return to the initial state.

Conductive pieces 55a and 55b are fixed to the upper sides of the storage parts 36a and 36b, respectively, so as to be in contact with the topmost prize balls 19 in the storage parts 36a and 36b. Also, storage portions 362.36b are provided on both sides of the nest 45.
The conductive piece 56a is placed in contact with the prize ball 19 at the bottom of the
, 56b are attached. By detecting that the conductive piece 55a and the conductive piece 56a1 and the conductive piece 55b and the conductive piece 56b are electrically connected via the prize balls 19 in the storage parts 36a and 36b, respectively, a specified number of prize balls 1
9 is stored in the storage parts 36a and 36b.

The operation of the pachinko machine configured as described above will be explained with reference to the circuit configuration shown in FIG. 4. When a safe sphere occurs, the safe sphere detector 17 outputs a pulse signal corresponding to the number of safe spheres. The pulse signal thus obtained is input to the counter 60 as an addition pulse. If the count value in the counter 60 is other than rOJ, a high level signal (hereinafter referred to as H signal) is sent to the payout signal generation circuit 61 and lamp drive circuit 62.
is being supplied.

While the H signal is input to the payout signal generation circuit 61, the solenoid drive circuit 63 drives the solenoid 52 at regular intervals. During this certain period of time, the prize ball dispenser 2
2 performs one payout operation, and the payout detection lever 30 swings once to turn off the microswitch 33 again.
The setting is longer than the time it takes to do so.

When the solenoid 52 is driven in this way, the prize ball payout device 22 is activated as described above, and the storage portion 36a of the prize ball payout device 22 is activated.
, 36b, a certain number of prize balls 19 are paid out all at once. The prize ball 19 thus paid out causes the payout detection lever 30 to swing once, turning on the microswitch 33 only once. A signal indicating that the microswitch 33 is turned on is input to the counter 60 as a subtraction pulse, and is also input to the lamp drive circuit 64 . As a result, the count value of the counter 60 is decremented by "1", and the payout indicator lamp 12 is turned on to confirm that the prize ball has been paid out.

If there is only one safe ball, the count value of the counter 60 becomes "0", so the payout signal generation circuit 61.
Since the H signal is no longer supplied to the lamp drive circuit 62, the credit lamp 13 is turned off and the operation of the solenoid 52 is also stopped, thereby completing the payout.

On the other hand, if, for example, safe balls come in consecutively, additional pulses will be supplied to the counter 60 while the prize balls are being paid out as described above, so the solenoid 52 operates continuously at the predetermined time intervals. Then, each time the micro switch 33
The subtraction pulse is supplied to the counter 60, and the counter 6
The payout ends when the count value of 0 reaches rOJ. Of course, the credit lamp 13 remains lit until the prize ball dispenser 22 is activated the number of times that matches the number of safe balls, but it is turned off when the count value of the counter 60 reaches "0". Ru.

The amount of prize balls 19 in the prize ball tank 20 decreases and the lever 26 cannot be rotated to the right against the bias (then the lever 26 is rotated to the left and the microswitch 27 is turned oFF'.

When the OFF signal from the microswitch 27 is input to the lamp drive circuit 66, the prize ball shortage indicator lamp 11 lights up to indicate that there are no prize balls 19 in the prize ball tank 20. At the same time, the OFF signal is
Input is input to a ball firing device 67 that is activated by the operation of the handle 1 to fire pachinko balls 2, and a ball supply device 68 that sends prize balls 19 to the prize ball detector 20, which prohibits the operation of the ball firing device 67 and supplies balls. Activate device 68.

The OFF signal obtained from the microswitch 27 is
It is also input to the solenoid drive circuit 63. When the prize balls 19 become insufficient in the prize ball tank 20, driving of the solenoid 52 is prohibited. In other words, an action is performed to prevent in advance that the prize balls 19 will become insufficient and the prize ball payout device 22 will not be able to pay out a certain number of prize balls 19. During this time, the count value of the safe balls in the counter 60 is maintained as it is, so when the lever 26 turns right and the micro switch 27 is turned on as a result of replenishing the prize balls 19, the prize balls 19
The payout will continue.

Note that even if the microswitch 27 is turned off,
Since a certain amount of prize balls 19 are prepared in the gutter 21 from the lever 26 to the prize ball payout device 22, it is possible to pay out prize balls several more times. Therefore, in order to effectively use the prize balls 19, a prize ball dispenser 22 is installed instead of the lever 26 and the microswitch 27, as shown by the two-dot chain line in FIG.
A prize ball detector 71 made of a photo sensor or the like may be provided at a position close to the entrance of the ball.

A continuity signal from the continuity detection circuit 70 is also input to the solenoid drive circuit 63 . The continuity detection circuit 70 connects the continuity pieces 55a and 56a provided in the storage parts 36a and 36b of the prize dispenser 22, and the continuity pieces 55b and 56.
Each of b outputs a conductive signal when electrically connected via the prize ball 19. That is, the continuity detection circuit 70 detects that the prize ball payout device 22 is in a state where it can pay out a fixed number of prize balls 19. Therefore, when the conduction signal cannot be obtained, by prohibiting the operation of the solenoid drive circuit 63, it is possible to prevent the prize ball 19 from being paid out with the valency below a certain value.

If a continuity signal is not obtained from the continuity detection circuit 70,
Normally, the microswitch 27 is also turned off, and there is often a shortage of prize balls 19, but the microswitch 27 is turned off even though the conductive signal cannot be obtained.
If it is N, it means that a ball is jammed between the microswitch 27 and the prize ball dispenser 22.

Therefore, when the conduction signal is not obtained and it is detected that the microswitch 27 is turned on, it is also effective to display a warning of a clogged bulb.

〔Effect of the invention〕

As described above, in the pachinko machine of the present invention, one activation of the prize ball dispenser is detected by detecting a certain number of prize balls that are dispensed all at once from the prize ball dispenser, and thereby the safe The count value of a counter that counts the number of balls is subtracted. Therefore, when the prize ball dispensing device operates but no prize balls are actually put out, the counter is not decremented, so that the action of putting out the prize balls is very reliable. Furthermore, although the prize balls to be paid out are detected, it is not necessary to detect each prize ball one by one, so the high-speed payout function of the prize balls is not hindered.
