Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball hitting device for a pinball game, and more particularly to a ball hitting device for a pinball game machine that is capable of detecting a platform where a player makes an illegal ball hitting operation.

BACKGROUND OF THE INVENTION As is well known, in pinball game machines that use pachinko balls to play games such as the one-hole pachinko game machine,
Electric ball hitting devices that use electric power to hit pachinko balls are becoming popular.

FIG. 1 is an external perspective view of a pachinko machine equipped with an electric ball hitting device. The background behind this invention will be explained with reference to FIG.

A game board 2 is provided on the front of the pachinko tJi 100. Further, a ball supply tray 7 into which pachinko balls are placed is installed below the game board 2, and a ball hitting device 1 is further provided on the lower right side of the tray 7. The player puts pachinko balls into the ball supply 1117 and sweeps the ball hitting device 1 to play the game by hitting the pachinko balls one after another onto the game board 2.

The ball hitting device 1 is operated as follows. Operation handle 10
By rotating the ball strength adjusting lever 12, for example, in the right direction, a ball hitting operation is started, and the strength of the ball hitting can be adjusted according to the degree of rotation. Therefore, when a 3H player plays a game, he/she adjusts the strength of the ball hit by controlling the operation handle 10 with his/her hand, and rotates the bar 12 with his/her fingers to perform a 5π trick.

However, when the batting strength adjusting lever 12 is rotated, for example, by inserting a matsushi tool into the gap between the adjusting lever 12 and the operating handle 10, the batting strength adjusting lever 12 is fixed in the rotated state. In addition, there were quite a few players who cheated by playing games with other Bajinko snoring games. Therefore, in order to prevent the above-mentioned fraud, we have proposed a device in which the touch electrode 11 is provided on the operation handle 10.In this device, the player's hand is placed on the touch electrode 11 during normal rubbing. If the touch electrode 11 is touched and the touch electrode 11 is grounded, and if there is an unauthorized operation, the touch electrode 11 is not grounded, and accordingly, for example, a warning is issued.

However, recently, in a ball hitting device provided with such a touch electrode 11, the touch electrode 11 and a metal frame 4 provided around the front surface of a pachinko machine 9100, for example, are connected by a conductive powder 9, and the touch electrode 1 A new fraudulent operation has begun that gives the same effect as if the player's hand had touched the player's hand.

OBJECT OF THE INVENTION The object of the present invention is to prevent the above-mentioned fraudulent acts, and to provide a ball hitting device for pinball players that can detect fraud.

SUMMARY OF THE INVENTION Simply put, this invention uses a touch electrode that detects the touch of a player's hand and a This is a ball hitting device for a pinball game calendar, which is equipped with a touch detection circuit and a circuit for detecting an illegal game state.

The circuit for detecting this illegal gaming state detects an electrical change, for example, a potential difference, between the touch electrode and the metal of the island placed on the metal frame 15j support 1f provided on the front of the gaming machine. Based on the potential difference, it is detected that the touch electrode has been improperly grounded.

The above-mentioned objects and features of the present invention will become clearer from the following description of embodiments with reference to the drawings.

Embodiment FIG. 2 is a perspective view of a ball hitting device according to an example of the present invention. Referring to FIG. 2, the structure and operating method of the ball-striking limb 81 will be explained 7+2.The mounting member 20 has a leg 13 on it.
[operation C] When the nodle 10 is engaged, the Ω of the mounting member 20 is
A fan-shaped float 14A is attached to the shaft 13.

The sweeping handle 10 is provided with a ball hitting strength adjusting lever 12. The batting strength adjustment lever 12 has its own lever 12.
The player grasps this operation handle 10 with his/her hand, places his or her finger on the projection 12a of the adjustment lever 12, and rotates the ball hitting strength adjustment lever 12. However, the sector gear 14A also rotates in the same direction via the shaft 13. The movement of sector gear 14A is gear 14B.
14. It is transmitted to C. And the wire A whose one end was fixed to the car 14C thereby
215 is pulled, and a force is applied to the batting rod 17 attached to the bent end of the wire 15 via a spring 16. this(
As a result, the hitting radius of the pachinko balls hit by the hitting ball rod 17 is evened out.

Further, when the sector gear 14A rotates as described above, the sector gear 14A comes into contact with one end surface of the sector gear 14A.
2 is driven, and the microswitch 21 is turned on. When this switch is turned on, the motor 18 is energized,
The moving rod 17 performs a ball motion.

Furthermore, a touch plate 11a, which is an example of a touch electrode, is provided on a part of the outer peripheral surface of the operating handle 10. This touch plate 1'1a is made of a band-shaped metal ib<, and is attached to the outer peripheral surface of the operating handle 1o in the circumferential direction.

Normally, when operating the game control or batting device, you will touch this touch board 11a.Touch board 11a
After that, the touch detection circuit is connected to the touch detection circuit.

In this embodiment, the operation handle 1o has a hemispherical shape with a portion thereof cut off, so that it has the advantage of being easy to grasp and operate.

FIG. 3 is a side sectional view of another embodiment of the ball hitting handle;
The feature of FIG. 3 is that instead of attaching the touch plate 11a to the operating handle 10, at least a portion of the outer peripheral surface of the operating handle is plated to form a plating electrode f7Q i -t l). By forming the plating electrode #X11b instead of attaching the touch plate 11a in this manner, the manufacturing process can be simplified and the number of parts can be reduced.

The embodiments of this invention have been described above in detail from the perspective of accommodation. Next, embodiments of the present invention will be described in detail from an electrical point of view.

FIG. 4 is a schematic block diagram of a circuit according to an embodiment of the present invention. The touch electrode 11 is connected to a touch detection circuit 30. The touch detection circuit 30 detects when the player's hand is touching the touch electrode 11, that is, when the touch electrode 11 is in contact with the player's hand.
When is grounded, for example, a high level output is given to the AND gate 26. The metal frame 4 is electrically connected to a fraud detection circuit 25. Further, the fraud detection circuit 25 is connected to the touch electrode 11. This fraud detection circuit 25
is a circuit that detects the potential between the metal frame 4 and the touch electrode 11. The fraud detection circuit 25 outputs, for example, a high level output when there is a potential difference between the metal frame 4 and the touch electrode 11, that is, when the metal frame 4 and the touch electrode 11 are not electrically connected. do.

The output 1 of the fraud detection circuit 25 is given to the display device 6 and the notification device 5, for example. As a result, when the metal frame 4 and the touch electrode '11 are electrically connected by the conductive wire 9 (the first wire etc.), that is, when fraud is committed, the display device 6 and the notification device 5 notify the user of this fact. .

The output of the fraud detection circuit 25 is also applied to the ant gate 26. Therefore, when the ball hitting device 1 (FIG. 2) is operated normally, the antenna driver 26 supplies a high level output to the motor drive circuit 40.

The motor 18 is thereby driven.

FIG. 5 is a detailed circuit diagram of the Pi schematic block diagram shown in FIG. 4. First, the configuration of the touch detection circuit 30 shown in FIG. 5 and the level of the output signal will be explained in detail.

Noagu 1~. The output of the pulse generating port vI36, which is formed by a resistor and a capacitor, is given to the cell 1 to terminal S of the flip-flop 35 via the variable resistor 34, and
The signal is applied to the reset terminal R of the control flop 35 through the series connection of resistors 33 and 32. The touch electrode 11 is connected to a connection point P between the resistors 32 and 33 via a capacitor 31. Flip-flop 35 is 2
The output of the NOR gate 35S is applied to one input terminal of the AND gate 26.

Next, consider the voltage states of the output voltage EQ of the pulse generating circuit 36, the input voltage VsJ3 to the let terminal S of the flip-flop 35, the input voltage V to the reset terminal R, and the output voltage Vo of the flip-flop 35.

First, adjust the variable resistor 34 to Vs<ν.

Set it so that That is, the resistance 'M Rs of the variable resistor 34 is the resistance value R of the series connection of the resistors 33 and 32.
Set it to be greater than 5.

Here, the Noah gate 3 that constitutes the flip 70 tube 35
58.35-R is composed of, for example, C-MCS, and when viewed from the input side of the Noritsu flop 35, can be thought of as capacitors C7 and C2, respectively. So, now 1. When the voltage Eo is applied from the pulse generation circuit 36 to the Noritub flop 35, the time constant for charging the capacitor 2 is τ. and τ, then τ, ˜R9C5 τt==Ric*. Here, if C, -C□, τ,〉τR(R
s>R1.

Therefore, considering the time constant, EQ,\,'3. \・'1
The relationship is illustrated in FIG. 6. More specifically, the voltage E from the pulse generating circuit 36.

When this is applied, the reset terminal R of the Noritsubu flop 35 becomes high level. Then, after a predetermined time delay (this predetermined time delay arises from the difference in time constant), the set terminal S
becomes high level. And voltage E. If it disappears,
The voltage levels of set terminal S and reset terminal R fall at a predetermined time constant. Note that in FIG. 6, VtH represents the threshold level of the input terminal of the flip-flop 65.

Next, consider the case where the touch electrode 11 (FIG. 5) is touched. At this time, when viewed from the input side of the flip-flop 35, that is, from the output terminal side of the pulse generation circuit 36, it can be thought that the capacitor 31 is connected in parallel to the NOR gate 35R at the connection point P between the resistors 32 and 33. .

Therefore, Noagu 1-35 R considered as a capacitor
The time constant τ, for charging the capacitor 31 is delayed by the amount of time required to charge the capacitor 31, and becomes τ,′. At this time, τR′〉
If the value of the capacitor 31 is selected so that τ5, the voltage waveform at the reset terminal R will rise later than Vs, as shown by the dotted line in FIG.

FIG. 7 shows the output voltage EO output from the pulse generating circuit 36 (FIG. 5) + the differential voltage of the flip-flop 35;
Two lightning pressure v3. Reset terminal voltage and output terminal voltage v
FIG. 3 is a timing diagram showing a temporal change relationship of o. Mainly referring to FIG. 7, (I) touch electrode 11 (FIG. 5)
(11) When the player's hand is not touching the tanner electrode 11, how is the output voltage level of the flip-flop 35 (Fig. 5) for each case? Explain how it changes.

<I) When the pulse voltage output from the platform pulse generation circuit 36 (FIG. 5) when the player's hand is not resting on the touch electrode changes at regular intervals as shown in (A), the flip-flop 35 The voltage at the set terminal S of is increased as shown in (B). However, in response to the rise of the pulse voltage EO, the voltage at the terminals increases by 5 with a time constant, and exceeds the threshold value vTIJ at time t2. In this way, once the threshold value V T8 is exceeded, the flip-flop 3
The set terminal S of No. 5 becomes high level. Also, the voltage EO
In response to the fall of Vs, Vs falls with a time constant τ5.

Similarly, the voltage at the reset terminal S changes as shown in (C). The difference from the voltage of the set terminal ~′ mentioned above is
The only difference is the rising and falling time constants τ6. Therefore, the voltage at the reset terminal R at time t
, the level is high.

When the voltage V of the set terminal S and the voltage V8 of the reset terminal R change at the timing described above, the output Vo of the Noritub flop 35 (FIG. 15) changes as shown in (D). That is, the output voltage Vo becomes a pulse voltage that rises at time t1 and falls at time [2].

(II) When the touch electrode is touched -C In this case, as shown in (B'), the voltage opening of the set terminal S is the same as that of the lifting platform where the touch electrode is not touched, but The voltage state of reset terminal R is different. That is, (C
'), the voltage at the reset terminal S rises with the rise of the pulse voltage EO, but the time constant is τ8.
' and rises slowly. Therefore, first, the set terminal S of the flip knob 35 becomes high level, and then the reset terminal R becomes high level. If the set terminal S and the set terminal R change in this order, the output level of the flip-flop 35 becomes (D'
). That is, the output snow pressure of the flip knob 35 becomes a pulse voltage that rises in response to the fall of the set terminal S and falls in response to the rise of the set terminal S.

The changes over time in the output voltage of the flip-flop 35 have been explained in detail above.

Next, returning to FIG. 5 again, the motor drive circuit 40 will be explained. The motor drive circuit 40 is turned on by a switching transistor 42 (including a no-coil 43), and when the relay contact 44 is turned on by the relay coil 43, the motor 18 can be driven.

A switching voltage applied to the base of transistor 42 is provided from AND gate 26.

As already explained, the outputs of the fraud detection circuit 25 and the touch detection circuit 30 are respectively applied to the input terminals of the AND gate 26. Now, when the touch electrode 11 and the metal frame 4 are not connected, that is, when no unauthorized operation is performed, the output of the unauthorized detection circuit 25 is a high-level snow pressure output as described above. Therefore, the AND gate 26 is in the dynamic ('#lε2 state.By the way,
Touch detection times i? The output of &30, in other words, the output Vo of the flip-flop 35, is output as a pulse voltage as described above. Therefore, the output of the AND gate 26 is almost the same as the output V0 of the touch detection circuit 30.

Now, when the player's hand is not attached to the touch electrode 11, the voltage output from the AND gate 26 is as shown in FIG.
) is a pulse voltage with an extremely narrow pulse width. When this pulse voltage is applied to the motor drive circuit 40, the voltage is absorbed by the C-R circuit 41 provided in parallel to the base of the switching transistor 42, and the switching transistor 42 is not turned on. Therefore, no current flows through the relay coil 43, and the contacts 44 remain open.

Next, when the player's hand touches the touch electrode 11, the output voltage of the AND gate 26 becomes a pulse voltage with a relatively wide pulse width as shown in FIG. 7(D').

This pulse voltage cannot be absorbed by the C-R circuit of the motor drive circuit 40, and the voltage is applied to the base of the switching transistor 42, turning the switching transistor 42 on. Therefore, the relay 43 operates and the contact 44 closes, allowing the motor 18 to be driven.

Further, referring to FIG. 5, if the touch electrode 11 and the metal frame 4
Consider, for example, a case where a fraudulent connection is made by electrically connecting a conductor. At this time, the output of the fraud detection circuit 25 becomes low level, and a low level signal is applied to one input terminal of the AND gate 26. Therefore, the AND gate 26 becomes inoperable, and even though the output voltage pulse from the touch detection circuit 30 changes as described above, the output body pressure of the AND gate 26 is always at a low level. Therefore, the switching transistor 42 is not turned on and the motor 18 is not driven. In other words, the touch electrode IV and the metal frame 4 are not turned on.
If a mistake is made to electrically connect the ball-hitting device to the ball-striking device, the drive voltage of the motor of the ball-hitting device (:λ) is set to 71, so that there will be no damage.

Furthermore, the output of the fraud detection circuit 25 is inverter: 27
; 2 to the display device 6 and the ÷H device 5.

Hoshisotake 5 is, for example, Pachinko Kei 100 (Figure '1)
A fraud detection circuit installed in the corner of the front of the J3 will detect fraud and alert 9! It makes an I sound.

The display device 6 is displayed in one corner of the game board 2, for example, 1oo (FIG. 1) for pachinko, and performs fraud detection display and the like.

As above, in this embodiment, the touch detection circuit 30
and the output of the fraud detection circuit 25, the batted ball J
Since Tanabata is held at 3 o'clock, the ball hitting device cannot be swept in the event of fraud, and fraud can be detected and prevented more completely.

Furthermore, by providing a display device 6 which operates in response to the output of the fraud detection circuit 25, an attendant at a pachinko parlor, for example, can immediately know that a fraud has been committed.

FIG. 8 is a partial external view of a 6-ball game to which the present invention is applied. The third advantage of FIG. 8 is that an insulating plate 24 is inserted into the gate between the front of the pachinko machine 100 and the ball supply tray 7. Kogumo is next''; for a reason. Batted ball supply f
i! 17 or hit ball supply ■ [The pachinko balls 23 placed in the 17 and the metal frame 4 provided on the pachinko number ia side may be electrically connected. For example, some technicians handle the operation handle with their right hand and use their left hand to handle the n-ball! There is a person who has a habit of touching J7's Pachinko King. In such a case, the touch plate of the operation handle and the metal frame 4 may interfere with the player's body and the Pachinko King 23 or the ball supply! l
It is conceivable that the fraud detection circuit 25 may be connected via 117, causing the fraud detection circuit 25 to become active. Therefore, an insulating plate 24 is provided to prevent such malfunctions.

FIG. 9 is a block diagram of a centralized management system for pachinko machines using the present invention. As shown in FIG. 9, a fraud detection circuit 1 is provided in a plurality of pachinko machines 910 or 1 ON and connected to the input control section 51 of the Rakuchukansanso@50. Input control unit 51: CPU52°ROr, 453, RA
h454 + Display] I; Meno C'RT 5533 and the alarm 56 are mutually connected via the data bus 57.

Therefore, by doing so, it is possible to centrally manage a plurality of pachinko techniques.

FIG. 10 is an external perspective view of an example of the central management device shown in FIG. 9. If such a centralized control device is used, for example, the number of a pachinko machine where a fraudulent act has been committed will be immediately displayed on the CRT 55 and notified by the alarm 56, making it possible to quickly take action against fraudulent acts. Become.

In the above description, the fraud detection circuit 1 is connected to the metal frame 4, but it may also be connected to, for example, a metal coffin forming part of an island on which pachinko machines are arranged side by side. or,
J7 m may be placed on both the island and gold frame 4.

As described in ``Effects of the Invention'', this emission W1 detects when the Tatsuna Air I1, the touch detection circuit, and the touch electrode are grounded illegally through the anti-tamper device in the ball hitting device of the pinball game machine. Since a tampering detection circuit is provided, if the ball hitting device is tampered with, it can be immediately detected. Further, it is possible to prevent or prevent unauthorized operation of the ball hitting device.
